As described above, the case where the present invention is applied to the camera has been described as an example, but the present invention can be applied to portable electronic devices other than the camera.

As described above, according to the first embodiment of the present invention, air can be supplied into the battery chamber. In addition, air can be supplied simply and reliably without complicating the structure.

In the above-described first embodiment, air is supplied into the battery chamber by providing an opening such as an air hole. Here, for example, assuming a camera as a portable electronic device, the camera is carried by the user, and the opening is closed by the hand that is gripped. At the time of required use, it may not be possible to supply sufficient air to the fuel cell.

Therefore, it is sufficient if the camera can be operated in a short time, so it is enough to use it at the same time as a secondary battery and prepare electric means that plays the role of a backup power supply, or make the battery room sufficiently larger than the battery. However, by increasing the capacity of the battery compartment, it is conceivable to extend the power generation time even when the inflow of outside air stops.

However, these methods have the problems of increasing costs and increasing the size of the camera.

Accordingly, a second embodiment of an electronic device to which the present invention is applied will be described.

13 to 16 show configuration examples of a digital camera as an electronic device to which the present invention is applied. Figure 13 shows the configuration of the front appearance of the digital camera 101. ing.

As shown in FIG. 13, a lens barrel 106 is disposed slightly to the right of the center of the housing 102. The lens barrel 106 holds a taking lens 107 used for photographing inside. At the upper end of the digital camera 101, at the upper left of FIG. 13, a shirt button 103 is arranged. In the figure of the lens barrel 106, a finder 105 is arranged on the upper side. The user looks at the viewfinder 105, confirms the subject (not shown), and presses the shutter button 103 at a predetermined timing to photograph the subject.

In the figure of the lens barrel 106, a flash 104 that emits a flash when the amount of light is insufficient and illuminates the subject is arranged at the upper left. In the figure of the casing 102, a battery cover 108 is provided at the lower left, which is opened and closed at the time of maintenance or replacement of the fuel cell 123 (FIG. 15) of the battery chamber 112 (FIG. 14).

FIG. 14 shows the layout of main components as viewed from the front of the digital camera 101. The battery compartment 1 12 is located at the lower left of the lens barrel 106 in the figure, and is located on the bottom surface of the digital camera 101. On the left side of the lens barrel 106, a flash condenser 113 for storing electric power to be supplied to the flash 104 is arranged. On the left side of the flash capacitor 113, a flash circuit 114 for controlling the operation of the flash 104 is arranged. A memory card 115 for storing image data of a photographed subject is disposed below the flash circuit 114 in the figure and above the battery chamber 112 in the figure.

At the lower right of the lens barrel 106, a lens barrel motor 111 is arranged. The rotation of the lens barrel motor 111 is transmitted to the gear 109 via the lens barrel drive gear system 110. The gear 109 is engaged with the lens barrel 106, and when rotated, moves the lens barrel 106 forward and backward. FIGS. 15 and 16 show the configuration of a vertical section near the lens barrel 106 of the digital camera 101. FIG. 15 shows the state when the lens barrel 106 is collapsed (the power is off). FIG. 16 shows a state when the lens barrel 106 is protruding (power is on). An air hole 122 communicating with the battery compartment 112 is formed in the bottom surface 102A of the housing 102, and a lower portion of the fixed cylinder 116 holding the lens barrel 106 communicates with the battery compartment 112. I will do it T JP2003 / 016924

14

Thus, an air hole 120 is formed.

Inside the lens barrel 106, there is arranged a shirt unit 119 for controlling the supply of light from a subject incident through the taking lens 107 to the image pickup device 118. Behind the lens barrel 106, a mounting board 117 on which various circuits for controlling the digital camera 101 are incorporated is arranged. An image pickup device 118 that converts a light signal from the object into an electric signal and converts it into a digital image is also disposed on the mounting substrate 117.

A water-repellent sheet 1 2 4 that has both air permeability and water repellency is attached to the battery compartment 1 1 2 side of the air hole 1 2 2 so that air can pass through, but water and dust can pass through the battery compartment 1 1 2 They are not allowed to enter. Similarly, a water-repellent sheet 121 is attached to the battery room 112 side of the air hole 120.

When the user turns on a main switch (power switch) (not shown), the lens barrel motor 1 1 1 is driven, and the rotation is performed via the lens barrel drive gear system 110 and the gear 109. When the lens barrel 106 protrudes, the state shown in FIG. 16 is obtained, and between the shirt unit 1 19 on the rear side of the lens barrel 106 and the image sensor 1 18 However, a storage unit 125 for storing air is generated (the volume of the storage unit 125 is increased). Therefore, at this time, the air pressure in the storage section 125 decreases, and outside air is taken in from the air hole 122 and supplied to the storage section 125 from the air hole 120 through the battery compartment 112. , Stored.

As a result, after that, when the digital camera 101 is used, even if the air hole 122 is closed by the user's hand, the air in the storage unit 125 flows into the battery chamber through the air hole 120. Since it is supplied to 112, the fuel cell 123 can generate power for a while (while the air hole 122 is closed by the user's hand).

As described above, according to the digital camera 101 of FIG. 13, when the digital camera 101 is used (when the power is on), the storage unit 1 generated by the projection of the lens barrel 106 is generated. Even if the flow of air from outside the digital camera 101 stops due to the air accumulated in the fuel cell 25, the power generation of the fuel cell 123 can be continued.

When the LCD monitor 3 8 4 is closed, the rubber 3 8 9 located on the right side in Fig. 4 3 of the LCD 3 9 9 'comes into contact with the air hole 3 9 2 and adheres closely to the surface with the air hole 3 9 2 Therefore, the dust resistance of the LCD monitor 384 when not in use can be improved.

A water-repellent sheet 94 having both air permeability and water repellency is affixed to the battery compartment 3 8 3 side of the air hole 3 9 2 so that air can pass therethrough, but water and dust can pass through the battery compartment 3 8 3 So that they do not enter. In the digital camera 381, shown in Fig. 41, when the LCD monitor 384 is not used, the air hole (not shown) on the bottom of the battery compartment 3883 of the digital camera 381, is connected to the battery compartment 383. Supply outside air.

According to the digital camera 381 shown in FIG. 41, the air hole 392 supplements the air supplied from another air hole (not shown) when using the LCD monitor 384, which consumes a large amount of power. The LCD monitor 384 can block the air holes 392 when the LCD monitor 384, which consumes less power, can be supplied to the room 383, thereby preventing the accumulation of dust. Can be.

In the digital camera 3381 shown in Fig. 41, the LCD monitor open / close detection switch 391 is used as a power supply switch for the LCD monitor 38.4 because of the presence of the viewfinder 386. 6 is not provided, and the camera that shoots while viewing the display image of the LCD monitor The detection switch 391 can be a power switch.

As described above, the case where the present invention is applied to a digital camera has been described as an example. However, the present invention can be applied to a camera using a film and other display devices.

As described above, according to the third embodiment of the present invention, it is possible to prevent a user from manually closing an opening for supplying air of a fuel cell, and to prevent dust from accumulating in the opening. Can be prevented.

In the third embodiment, the opening is closed by the grasped hand, so that the air can be sufficiently supplied to the fuel cell particularly during use when power supply is required. In order to cope with the problem of disappearance, the problem of dust accumulating in the openings, or the appearance that is not desirable, the openings are usually not visible from the outside, but allow air to be taken in during operation. Part was provided.

In addition, the camera consumes a considerable amount of power.For example, when using a stop port, it is difficult to supply sufficient oxygen to the fuel cell because sufficient power is required. In such a case, it may be difficult to perform the strobe operation normally. In other words, the opening alone may not supply enough oxygen to perform the strobe operation.

In response to this, a fourth embodiment of an electronic apparatus to which the present invention is applied will be described as another embodiment using a strobe.

FIG. 44 is a block diagram illustrating an example of an electrical configuration of a camera 401 as an electronic device to which the present invention has been applied.

The camera 401 has a CPU (Central Processing Unit) 411, a fuel cell 412, a main switch (switch) 413, a release button 414, a distance measuring section 415, a photometric section 416, Strobe 4 17, stop port position detector 4 18, feed motor 4 19, shutter 4 20, display 4 2 1, AF (Auto Focus) LED 4 2 2, It is composed of LEDs 4 and 3 for the mouthpiece.

The fuel cell 4 1 2 uses methanol as fuel and uses oxygen in the air, It generates energy and supplies necessary power to each part of the camera 401 when the main SW 413 is turned on.

When the user starts using the camera 401 (when turning on the power), the user operates the main SW 413. The release button 414 is operated by the user when operating the shirt 420. The CPU 411 controls the operation of the camera based on inputs from the main SW 413 and the release button 414.

The distance measuring section 415 measures the distance to the subject. The photometry section 4 16 measures the brightness of the subject. The strobe 417 generates a flash and illuminates the subject. The strike port position detecting section 418 detects whether the strobe 417 is at the storage position or the use position. The feed motor 419 performs a feeding process of winding or rewinding one frame of the film. The shirt 420 exposes the film by opening and closing. The display unit 421 performs display according to the operation of the camera, such as display of the number of films and a warning display.

Based on the measurement results (distance to the subject and brightness of the subject) of the distance measuring unit 4 15 and the photometry unit 4 16, the CPU 411 determines the speed of the shutter 420 during shooting and the flash 4 17 The necessity of the camera 401 is determined, and the overall operation of the camera 401 is controlled. Further, the CPU 411 controls the AF LED 422 in accordance with whether or not the distance measurement has been normally performed by the distance measuring section 415 (the distance has been measured). For example, the CPU 411 turns on the AF LED 422 when the distance measurement is successfully performed by the distance measurement unit 415, and the distance measurement is not normally performed by the distance measurement unit 415. If not, blink the AF LED 422.

Further, the CPU 411 controls the strobe LED 423 according to whether or not the strobe 417 is being charged. For example, the CPU 411 blinks the strobe LED 423 when the strobe 417 is being charged.

FIG. 45 is a flowchart illustrating the photographing processing in camera 401 in FIG. In step S1, the CPU 411 determines whether the main SW 413 is turned on. If it is determined that the main SW4 13 is not turned on, the CPU Step 41 1 waits until the main SW 4 13 is turned on.

If it is determined in step S1 that the main SW 413 has been turned on, the CPU 411 advances the process to step S2, activates the camera, and supplies necessary power from the fuel cell 412 to each unit. At this time, the CPU 411 blinks the strobe LED 423, turns on the strobe SW (not shown), and supplies power from the fuel cell 412 to the strobe 417 for charging. Also, the CPU 411 moves the strobe 417 from the storage position to the use position (for example, from the state of FIG. 49 described later to the state of FIG. 48).

In step S3, the CPU 411 controls the strobe position detection unit 418 to determine whether or not the strobe 417 is at the use position. If it is determined that the strobe 417 is at the use position (the position shown in FIG. 48 described later), the CPU 411 advances the process to step S4, and the photographing is instructed (the release button 41 4 has been operated). As shown in FIG. 48, when the strobe 4 17 is in the use position, air is supplied to the battery compartment 452, the description of which will be described later.

If it is determined in step S4 that photographing has not been commanded, the CPU 411 waits until photographing is commanded. If it is determined that the shooting has been commanded (the release button 414 has been operated), the CPU 411 controls the distance measuring section 415 and the light measuring section 416 to determine the distance to the subject and the brightness. Let me measure.

In step S5, the CPU 411 determines whether or not the distance has been measured by the distance measuring unit 415. If it is determined that the distance measurement has been successfully performed, the CPU 411 advances the process to step S6, turns on the AF LED 422, and shoots an object.

Specifically, the CPU 411 calculates the exposure time based on the measurement results measured by the distance measuring unit 415 and the photometric unit 416. The shutter 420 is operated only for the calculated exposure time, and the taking lens (not shown) of the lens barrel 432 (FIG. 46 to be described later) transmits light from the subject at the moment when the shutter 420 operates to a film (not shown). Exposure to After one frame has been shot, the CPU 41 1 controls the feed motor 4 19 to fill 03016924

31

The camera is transported by one frame (the part exposed by shooting).

If it is determined in step S5 that the distance measurement unit 415 has not measured the distance, the CPU 411 causes the AF LED 422 to blink, and the process proceeds to step S7. In step S7, the CPU 411 performs an error process such as displaying a message on the display unit 421 indicating that the distance measurement has not been normally performed.

When the main SW 4 13 is turned on, the strobe 4 17 should have been moved to the use position in the process of step S1, but an error has occurred for some reason and the strobe 4 17 has not been moved to the use position. is there. Therefore, in step S3, when it is determined that the strobe 417 is not in the use position (it is in the storage position shown in FIG. 49 described later), one of the openings 45 1 of the air holes 451 in FIG. Since A is closed and air cannot be supplied to the battery compartment 452, the CPU 411 proceeds to step S8 and warns the display 421 with characters, symbols, figures, LEDs, etc. Is displayed. This warning indicates that if the operation is continued as it is, sufficient oxygen (air) is not supplied to the fuel cell 412 and power is insufficient, so that the user must take measures to supply oxygen (air) to the fuel cell 412. When the user sees this warning, the user will take measures such as placing the strobe 417 in the use position.

After the processing in step S6, step S7, or step S8, the CPU 411 advances the processing to step S9, and determines whether the main SW 413 is turned off. If it is determined that the main SW 413 has not been turned off, the CPU 411 returns the process to step S3 and repeats the subsequent processes. As a result, the subject is photographed or a warning is displayed.

If it is determined in step S9 that the main SW 413 has been turned off, the CPU 411 advances the process to step S10, deactivates the camera 401, and ends the process. The user performs an operation of returning the strobe 417 to the storage position.

As described above, according to the processing in FIG. 45, the camera 401 allows photographing when the strobe 417 is in the use position of the strobe 417, and prohibits photographing when the strobe 417 is in the stowed position. FIG. 46 is a diagram showing the configuration of the front of the camera 401. A lens barrel 432 is provided in the center of the front of the housing 43 1 of the camera 401. A finder 433 is provided at the upper right of the lens barrel 432 in the figure, and a strobe light 4 17 is provided at the upper right of the view of the finder 433. Further, a release button 414 is provided on the left side of the upper surface in the drawing of the housing 431.

FIG. 47 is a diagram showing the configuration of the rear surface of the camera 401. In this example, a display unit 421 is provided in the center of the rear surface of the housing 431 of the camera 4 • 1. In the figure of the display section 42 1, a main SW 4 13 is arranged at the upper right. For example, when the main SW 413 is moved by the user to the right in the figure, the main SW 413 supplies an ON signal to the CPU 411, and when moved to the left in the figure, the main SW 413 is turned on by the user. W413 provides an off signal.

In the figure of the display unit 42 1, in the figure of the strobe 4 17 arranged at the upper left, in the figure of the display unit 421, in the figure of the display unit 421, at the upper left, a viewfinder eyepiece unit 441 is arranged I have. The user checks the subject by looking at the viewfinder eyepiece 441 during shooting. On the right side of the finder eyepiece 441, an AF LED 422 and a strobe LED 423 are respectively arranged above and below.

FIG. 48 shows the operation state of the camera 401, in which the strobe 4117 is rotated clockwise in the figure around the shaft 417A, and is in the use position protruding from the storage section 461. 2 shows a configuration of a side cross section in a state. The strobe 4 17 has a built-in lamp 462 that emits light and a reflector 463 that reflects light from the lamp 462. The fuel cell 412 is housed in a battery room 452. The air hole 45 1 communicates from the battery chamber 452 to the outside of the housing 43 1, and air outside the housing 43 1 of the camera 401 passes through the air hole 45 1 to the battery room 452. It is supplied and used for power generation by the fuel cell 412.

In addition, a drop-in position detector 418 is provided inside the housing 431 in the upper right part of the battery compartment 452 in the figure. The strobe position detector 4 18 has a conductive plate support 471, a conductive plate 472A, 472B, a support plate 473, and a lead wire 474A, 474B. It is composed of A conductive plate support 471 is arranged on the bottom of the strobe position detector 4 18 in the figure, and a non-conductive support plate 473 is partly on the top of the conductive plate support 471 in the figure. The conductive plate 472 A and the conductive plate 472 B are mounted therebetween. Lead wires 474 A and 474 B are connected to the conductive plates 472 A and 472 B, respectively. Further, the hole 481 is formed at a position corresponding to the projection 491 provided on the flash 4117 so that the flash position detecting section 418 and the storage section 461 communicate with each other. I have.

Therefore, as shown in FIG. 48, the tropo 4 17 is rotated clockwise in the figure around the shaft 4 17 A, and is in the use position protruding from the storage section 4 61. In this case, the conductive plate 472A and the conductive plate 472B are separated from each other, and the stop position detector 418 is connected to the lead wire 474A or 4 Even if a current flows through one of 74B, no current flows through the other, and the strobe position detecting section 418 can detect that the strike port 417 is at the use position.

FIG. 49 shows the camera 40 1 in a state where the strobe 4 17 is rotated counterclockwise around the axis 4 17 A in the storage position stored in the storage section 4 61. The configuration of the side cross section is shown. The air hole 451, which communicates with the battery compartment 452, has one of its openings 451A closed by the strobe 417, and the camera 4 External air is not supplied to the battery compartment 452, or even if supplied, not enough. Therefore, in step S8 in FIG. 45, the CPU 411 displays a warning on the display section 421 that oxygen is insufficient, and prohibits the photographing of the subject.

Specifically, when the strobe 417 is stored in the storage part 461, the projection 419 of the tropo 417 is inserted through the hole 481 of the housing 431. Then, since the conductive plate 472 A of the strobe position detecting portion 418 is pressed, the conductive plate 472 A is elastically deformed and comes into contact with the conductive plate 472 B. Therefore, when the strobe position detection unit 4 18 supplies a current to one of the lead wire 474 A or the lead wire 474 B from a circuit (not shown), the conductive plates 4 7 2 A and 4 7 2 B The current flows to the other through PT / JP2003 / 016924

34

The position detector 418 can detect that the strobe 417 is in the storage position. The CPU 411 displays a warning on the display unit 4 21 when the determination result indicating that the flash unit 4 17 is in the storage position is supplied from the storage port position detection unit 4 18.

As described above, in the present invention, when the strobe 417 is in the use position, air is supplied from the air hole 451, so that the fuel cell 412 can generate the required large energy. It can be supplied to each part of the camera 401. Also, if the camera 401 is in operation and the strobe 417 is in the stowed position, a warning message will be displayed and shooting of the subject will be prohibited, so shooting will be performed in a power shortage condition and malfunction will occur. This can be prevented, and the user's shooting operation can be made more reliable.

Another configuration example of a camera to which the present invention is applied is shown in FIGS. Portions corresponding to those shown in FIG. 46 are denoted by the same reference numerals, and description thereof will be omitted as appropriate. In this example, air holes 501a, 501b, and 501c are provided in the lower part of the strobe 417 in the figure and on the right side of the lens barrel 432. FIG. 51 shows a side cross-sectional configuration in a state where the camera 401 is in an operation state and the strobe light 4 17 is in the use position. The battery compartment 452 communicates with the outside through the air holes 451, and also communicates with the outside through the air holes 501a, 501b, and 501c. Therefore, the air outside the housing 431 of the camera 401 is not only supplied through the air holes 451, but also through the air holes 501a, 501b, and 501c. 4 52 is supplied.

Also, as shown in FIG. 52, when the strobe 4 17 is in the storage position, one opening 4 51 A of the air hole 45 1 communicating with the battery compartment 45 2 is Although closed by 4 17, the air outside the housing 4 3 1 of the camera 401 is supplied to the battery compartment 4 52 through the air holes 5 O la, 5 0 1 b and 5 0 1 c. You. Therefore, in the case of this embodiment, it is possible to allow the photographing even when the strobe light 4 17 is in the storage position. Of course, air holes 501 a, 501 b, 501 At least one of c may be opened only in the normal operation state, like the air hole 451.

As described above, in the present invention, when the strobe 417 is used, more air is supplied, so that the fuel cell 412 supplies necessary large energy to each part of the camera 401. can do.

In the above description, the number of the air holes 451 is one, but the air holes 451 may be divided and provided.

As described above, the case where the present invention is applied to a camera has been described as an example. However, the present invention can be applied to an imaging device other than a camera.

As described above, according to the fourth embodiment of the present invention, air can be supplied into the battery chamber. In addition, air can be supplied simply and reliably without complicating the structure. In addition, if more energy is required, more air can be supplied.

In the above-described fourth embodiment, when using a strobe, sufficient oxygen is supplied so as to perform a strobe operation.However, even when not using a strobe, sufficient oxygen is supplied. As a fourth embodiment, a fifth embodiment of an electronic apparatus to which the present invention is applied will be described.

FIG. 53 is a block diagram showing an example of an electrical configuration of a camera 600 as an electronic apparatus to which the present invention is applied.

The camera 61 has a CPU (Central Processing Unit) 611, a fuel cell 612, a main switch (switch) 613, a zoom switch (switch) 614, a release button 615, and a distance measuring section 6. It comprises 16, a photometry section 6 17, a lens barrel drive motor 6 18, a feed motor 6 19, and a shutter 6 21.

The fuel cell 612 uses methanol as a fuel, generates energy using oxygen in the air, and supplies power to the entire camera 601.

The user operates the main switch 613 when starting to use the camera 601 (when turning on the power). The zoom SW 6 14 is used by the user to perform zoom operations. Is operated by The release button 615 is operated by the user when the shirt 621 is operated. The CPU 611 controls the operation of the camera based on the inputs from the main SW 613, the zoom SW 614, and the release button 615.

The distance measuring unit 6 16 measures the distance to the subject. The photometry section 6 17 measures the brightness of the subject. The lens barrel drive motor 618 moves the lens barrel to a commanded position. The feeding motor 610 performs a feeding process of winding or rewinding the film 620 by one frame.

Based on the measurement results (distance to the subject and brightness of the subject) of the distance measuring unit 6 16 and the photometric unit 6 17, the CPU 611 determines the shutter speed and the flash (not shown) at the time of shooting. Judgment of presence / absence and the like is performed, and the overall operation of the camera 601 is controlled.

FIG. 54 is a flowchart for explaining the photographing process in the camera 601 in FIG. This process is started when the main switch 613 is turned on by the user.

In step S101, when a signal indicating that the main SW 6 13 has been turned on is input, the CPU 6 11 activates the camera.

In step S102, the CPU 611 determines whether or not the user has operated the zoom SW 614 to instruct zooming (instructing to change the magnification of photographing). If it is determined that the zoom command has been input, the process proceeds to step S103, in which the CPU 611 controls the lens barrel drive motor 618 to control the lens barrel 6 as shown in FIG. 3 Move 5 to the commanded position. When the lens barrel 6 35 moves, air is supplied to the fuel cell 6 12, which will be described later.

After the processing in step S103 or in step S102, when it is determined that the zoom instruction has not been input, the processing proceeds to step S104, in which the CPU 611 issues an instruction to shoot. Is determined (whether the release button 615 has been operated by the user). Shooting is not commanded (Release button

6 1 5 has not been operated), the process returns to step S102, Subsequent processing is repeated.

If it is determined in step S104 that shooting has been commanded (the release button 615 has been operated by the user), the process proceeds to step S105, in which the CPU 611 executes a process of shooting the subject. I do. Specifically, the CPU 611 controls the distance measuring unit 6 16 and the light measuring unit 6 17 to measure and obtain the distance to the subject and the brightness. Then, based on the measurement result, the CPU 611 controls the lens barrel drive motor 618 to finely adjust the position of the lens barrel 635 and calculate the exposure time. The shutter 621 is operated only for the calculated exposure time, and the shooting lens 638 of the lens barrel 635 (see FIG. 55 described later) is used to shoot light from the subject at the moment when the shutter 621 operates. Expose to 620. After the photographing of one frame is completed, the CPU 611 controls the feed motor 6 19 to transfer the film 620 for one frame (the portion exposed by the photographing).

After the processing in step S105, in step S106, the CPU 611 determines whether or not the main SW6 13 has been turned off. If it is determined that the main SW6 13 has not been turned off, the process proceeds to step S102. And repeat the subsequent processing.

If it is determined in step S106 that the main switch 613 has been turned off, in step S107, the CPU 611 sets the camera 6001 in a non-operation state as shown in FIG. The tube 635 is stored), and the process ends.

As described above, the subject in the camera 601 can be photographed by the processing in FIG.

FIG. 55 shows a horizontal cross-sectional configuration in a state where the camera 601 is in an operating state and the lens barrel 635 is extended to a predetermined position. FIG. 56 shows a horizontal cross-sectional configuration in a state where the camera 601 is not operated and the lens barrel 635 is housed in the camera 601. FIG. 57 shows a configuration of a vertical section of the camera 601.

In FIG. 55, a patrone chamber 632 is provided on the left side, a lens barrel 635 is provided substantially in the center, and a film chamber 634 is provided on the right side of the lens barrel 635. . A battery chamber 636 is provided between the patrone chamber 632 and the lens barrel 635. The fuel cell 6 12 is housed in the battery compartment 6 36, and the power from the fuel cell 6 12 is supplied to each unit that needs the power of the camera 61. The space 635 A behind the taking lens 638 included in the lens barrel 635 is in communication with the space of the battery chamber 636 by an air hole 651. Outside air flows into and out of the battery compartment 636 through an air hole 661 formed on the bottom surface of the camera cover 631 so as to communicate with the battery compartment 636.

The patrone chamber 632 contains a patrone 633, which is wound around a spool 637 of the film chamber 634 that is drawn from the patrone 633.

When the photographing process shown in FIG. 54 is performed, the feed motor 6 19 is controlled by the CPU 6 11, and the spool 6 of the film chamber 6 3 4 3 7

Next, the operation of supplying air to the fuel cell 612 performed with the movement of the lens barrel 635 will be described.

When the lens barrel 635 is extended from the stored state, the space 635A behind the lens barrel 635 changes from the state shown in FIG. 56 to the state shown in FIG. In other words, at this time, since the volume of the space 635 A increases, the pressure inside the space 635 A decreases, and the space of the battery compartment 636 communicates with the outside of the camera cover 631. Air holes 6 6 1 Air is taken in. The air taken in from the air hole 6 61 is supplied to the electricity chamber 6 3 6 and is further supplied to the space 6 3 5 A of the lens barrel 6 3 5 through the air hole 6 5 1 And stored.

When the lens barrel 635 is retracted from the extended state, the space 635 A behind the lens barrel 635 changes from the state shown in FIG. 55 to the state shown in FIG. Change. At this time, the air in the space 635 A behind the lens barrel 635 passes through the air hole 651. Then, the air is supplied to the battery chamber 636, and the air in the space of the battery chamber 636 is exhausted from the air hole 661.

As shown in FIGS. 55 and 56, the lens barrel 635 repeats the forward and backward movements in the space of the battery chamber 636 in which the fuel cells 612 are stored. The operation of supplying air is performed, and the air is refreshed. The fuel cell 6 1 2 performs a power generation operation using this air.

As described above, the battery chamber 636 in which the fuel cell 612 is stored, the air hole 661 communicating with the outside, and the air communicating with the space 635A behind the lens barrel 635 A hole 651 is provided, and each time the photographing process (the movement of the lens barrel by the process of step S103 in FIG. 54) is performed, the air in the lens barrel is supplied through one air hole, and Since the air is exhausted through the air holes, the air can be easily and reliably supplied to the fuel cell 612 without providing a special air blowing mechanism.

In FIG. 57, the air holes 661 are provided on the lower surface of the camera 601, but may be provided on the upper surface. Although only one air hole 651, 661 is provided, a plurality of air holes may be provided.

The case where the present invention is applied to a camera using a film (film camera) has been described above as an example. However, the present invention can be applied to a digital camera or to a portable electronic device other than a camera. You can also.

As described above, according to the fifth embodiment of the present invention, air can be supplied to the fuel cell. In particular, it is possible to supply air simply and reliably at a low cost, without providing a complicated mechanism for blowing air. ■

In the fifth embodiment described above, the case of a normal camera or a digital camera has been described. However, air is taken in a drip-proof camera having a drip-proof function that requires the camera to be sealed in a watertight manner. Since the place is limited and it is difficult to supply sufficient air, there is a problem that the performance of the fuel cell is not maximized and the performance is degraded.

In response, a sixth embodiment of an electronic device to which the present invention is applied will now be described. Will be explained.

FIG. 58 is a front view showing a configuration example of an external appearance of a drip-proof camera as an electronic apparatus to which the present invention is applied.

It is taken in and out of the camera 700.

FIG. 61 is a block diagram illustrating an example of an electrical configuration of the drip-proof camera 701. Note that, in FIG. 61, the portions described in FIGS. 58 to 60 are repeated, and the description thereof will be omitted.

A CPU (Central Processing Unit) 756 controls the entire operation of the drip-proof camera 701. In addition, the CPU 761 is based on a signal input from the zoom switch 771, the main switch 772 or the release switch 773, and an output from the distance measuring section 774 or the light metering section 775. Then, the lens barrel drive motor 715, the feed motor 776 or the shutter 777 is driven.

The zoom switch 771 is a switch for changing the focal length of the taking lens 728. By operating this zoom switch 7 71, the lens barrel 7 11 holding the taking lens 7 28 moves forward and backward, and the focal length of the taking lens 7 28 changes. The main switch 772 is a switch for putting the drip-proof camera 701 into an operating state. By operating the main switch 772, power is supplied from the fuel cell 714 to the drip-proof camera 701.

The release switch 773 is a switch for cutting the shirt 777 for shooting. By operating the release switch 773, the film is exposed by the shirt 777.

As described above, the user operates the drip-proof camera 701 by operating each switch according to the purpose. Based on the user's operation, a signal is input to the CPU 761 from the zoom switch 771, the main switch 772, or the release switch 773.

Distance measuring section 774 measures the distance to the subject based on the light from the subject, and outputs the measurement result to CPU 761. The photometry unit 775 measures the brightness of the subject based on the light from the subject, and outputs the measurement result to the CPU 761.

The lens barrel drive motor 715 moves the lens barrel 711 forward and backward in accordance with the control of the CPU 761. The feed motor 776 drives the sprocket 733 in accordance with the control of the CPU 761, and performs winding and rewinding of the film. The shirt 777 exposes the film under the control of the CPU 761.

Next, the lens barrel operation processing of the drip-proof camera 701 will be described with reference to the flowchart in FIG.

The user operates the zoom switch 771 to change the focal length of the taking lens 728. The zoom switch 771 outputs a signal corresponding to this user operation to the CPU 761. In response to this, in step S201, the CPU 761 determines whether or not the lens barrel 711 is to be advanced.

If it is determined in step S201 that the lens barrel 711 is not to be advanced, in step S203, the CPU 760 determines the lens barrel 7 based on the signal from the zoom switch 771. 1 It is determined whether or not 1 is to be retracted.

If it is determined in step S203 that the lens barrel 71 1 is to be retracted, in step S204, the lens barrel drive motor 7 15 Retract the cylinder 7 1 1. As a result, the volume of the lens barrel space 732 of the drip-proof camera 700 becomes small, so that the air in the lens barrel space 732 passes through the ventilation port 735, the battery compartment 733, and the ventilation non-flow. The water is released to the outside of the drip-proof force 701 through the aqueous filter 742 and the through hole 741.

If it is determined in step S203 that the lens barrel 711 is not to be retracted, the processing ends.

As described above, the air in the lens barrel space 732 is moved in and out of the drip-proof camera 701 by the forward and backward movements of the lens barrel 711. In addition, the operation of the zoom switch 771 for changing the focal length of the taking lens 728 is an operation that is often performed when a user takes a picture. The air in and out of 32 are also frequently executed.
