Description

TECHNICAL FIELD The present invention relates to a remote control device, and more particularly to a remote control device using light (including an infrared ray, a laser, etc.) as a signal transmission medium. Control device. 2. Description of the Related Art Today, many home appliances have a remote control device, and since the remote control method differs depending on the manufacturer, a remote control device is required for each device, and the storage and management of such devices are extremely complicated. Become ', Therefore, it is desirable to provide a remote control device that can control multiple types of devices with one device.

Conventionally, a so-called learning remote control is used, which receives a remote control modulated signal from each company, detects it, forms a remote control signal, and stores and uses this remote control signal in a memory designated by a remote control key. Device.

However, the carrier frequency of the remote-modulated signal depends on the manufacturer. Different and, also the range tooth force is quite wide and _{3 0 KH Z ~ 4 0 KH} Z. For this reason, conventionally, a detection circuit and a modulation circuit capable of covering such a wide frequency range were required, and this type of learning remote control device was complicated and expensive.

Conventionally, there is a remote control mounting device in which a remote control signal emitted from a remote control device is diffused by a reflection diffuser so that one remote control signal is diffused throughout the room.

However, if one remote control signal is spread in this way, the reception power on each side of the room is significantly reduced or uneven, and stable remote control of the equipment in the entire room cannot be performed.

Also, today, many home appliances are equipped with an emergency function. For example, in the case of an air conditioner, the use of this timer function enables power supply after sleep 〇 FF or power supply 0 N before waking up, making the living environment even more comfortable. In today's home automation industry, if you do not care about the cost, you want to add a timer function to the power terminals and individual lighting devices. This timer function is not only controlled by a timer provided in a curtain or individual lighting device or a centralized control device provided separately as in the case of TY or air conditioner, but also from a cost perspective. The spread of automation was alienated. Disclosure of the invention The present invention has been made to eliminate the above-mentioned drawbacks of the prior art. An object of the present invention is to provide a remote controller capable of controlling a plurality of types of equipment from a hand or by setting it in a holder. Provide a trolling device;

In order to achieve the above object, a remote control device of the present invention includes a remote control device having a light emitting element for each of a plurality of controlled devices, a remote control device for holding the remote control device detachably, and a remote control device. A holder having a beam reflector at a position corresponding to each light emitting element of the device. As a result, the remote control device emits a remote control beam from the light emitting element corresponding to each device, and the beam reflex of the holder relays each beam to each device without fail.

Also preferably, the remote control device comprises: a time keeping means for keeping time; a memory for storing information of a designated time and a remote control key; and a time keeping information of the time kept by the time keeping means and a designated time which is stored in the memory. Timer means for generating a remote control signal corresponding to the information of the remote control key stored in the memory by detecting a match with the information. Therefore, if this remote control device is set in a holder, it functions as a centralized control device that performs centralized timer control for not only TVs and air conditioners, but also curtains and individual lighting devices.

More preferably, the remote control device reads the remote control modulated signal from a corresponding address of the memory by pressing a remote control key, and a light emitting element. Transmitting means for driving W 1, receiving means for receiving an external remote control modulation signal, and sampling the remote control modulation signal received by the receiving means at a frequency higher than the carrier frequency of the remote control modulation signal Storage control means for storing the data at an address designated by a remote control key of the memory. Therefore, this remote control device faithfully learns the remote control signal of each company despite the difference in carrier frequency.

The remote control 100 has a built-in timer function. To set the timer, press the “TIMER” key. As a result, the display 120 displays the contents of the timer register (TMR). The _c timer registers are for TV, AC, and Right for ON and OFF, respectively, and the user can select any of these. For example, pressing the “0N” key on T \ 'selects the timer register for TV-0N and displays its contents. Press the TY “0 '” key again to select Τ \' — 0 FF timer register and display its contents: In the same way, press the AC or Right “0N” key. The corresponding timer register can be selected and its contents can be displayed. To adjust the timer time, press the “H” key. To adjust the minute, press the “M” key to add +1 to each display content. After adjusting the timer in this way, press the “SET” key to store the display contents in the corresponding timer register. As described above, since the remote control 100 has a timer function, it is possible to perform: Timer centralized control of a plurality of devices simply by placing the remote control 100 in the holder unit 200.

The control target of the remote control 1 • 0 is various electronic devices (home appliances), and the wireless remote control method of each company is also different. In addition, the remote control 100 of the embodiment has a function of learning (storing) the remote control signal of each company. That is, the remote controller 100 has a remote control signal receiving unit (not shown) on the bottom surface, and “MEM! Pressing key 1 63 activates the remote control signal receiver and the learning function. Details will be described later.

The remote control 100 can be seated and fixed to the holder unit 200 by one-touch operation as shown in the figure. The backrest part 201 of the holder part 200 supports the back of the remote control 100, and the left and right protruding parts 203 sandwich the left and right side faces of the remote control 100 so as to sandwich the remote control. The horizontal position of 100 is fixed. Furthermore, the claw portion 202 projecting halfway downward is latched in a concave portion (not shown) provided on the upper surface of the remote controller, and the upper, lower, left, right, and inclination of the remote controller 100 are always fixed at the proper positions. In addition, the remote controller 100 can be securely fixed to the holder unit 200 by one-touch operation, and the remote control signal light emitting unit 110 and a reflector 22 to 22 to 22 or 230, which will be described later. The optical system between 2 and 3 is always kept stable.

An arm portion 204 located in the upper middle portion of the holder 200 is provided so as to protrude so as to hold the front of the holder, and a proximity sensor 24 1 and an illuminator 25 1 are held at a tip portion thereof. The proximity sensor 24 1 detects the approach of a hand extended to the front of the holder 200, and the Illuminator 25 1 illuminates the operation surface of the remote control 100.

The protrusion 237 provided on the upper portion of the holder 200 supports the reflectors 230 to 232 via a shaft 236 that penetrates through the protrusion 237, and The infrared beams emitted from the signal emitting unit 110 are reflected in the desired directions by the respective reflectors 230 to 232, and are reflected to the remote control signal receiving unit of the corresponding device. Incident. Thus, the user can centrally control a plurality of devices by key operation or by a timer function.

The holder unit 200 has an intercom function, 253 is a speaker, 255 is a microphone (MIC), and 255 is a talk (TALK) button.

The cover 230 of the holder portion 200 can be attached by a one-touch operation from the front of the holder portion 200, and is preferably transparent to infrared rays and translucent to human eyes. It is composed of dark-colored acrylic material.

Fig. 2 (A) is an enlarged perspective view of the reflector 230 to 232 of the embodiment, Fig. 2 (B) is a rear perspective view of the reflector, and Fig. 2 (C) is an assembled view of the reflector. It is. In FIG. 2 (A), the shaft 236 is pushed into the hole of one of the projections 237, and further into the side hole of each of the pits 234 of the reflectors 230 to 232. 6, and both ends of the shaft 236 are axially fixed at both projections 237. As a result, the shaft 2 3 6 itself does not rotate _c

In FIG. 2 (B), since there is a suitable friction between the side hole of the pit 234 and the shaft 236, the pit 234 is shuffled by applying a force with a hand or a tool. G around 2 3 6 (X car). Also, when you release your hand, pit 234 is held at that angle. Since the shaft 236 is fixed on the shaft, for example, applying a force to the reflector 233 has no effect on the angles of the other reflectors 231 and 232. In FIG. 2 (C), push the pin 235 through one of the vertical holes of the pit 234, and then pass the pin 235 through the vertical hole provided in the reflector 233. The tip of the pit into the other vertical hole of pit 2 3 4 Since there is appropriate friction (preferably the pit 234 is larger) between the vertical hole of the pit 234 and the vertical hole of the reflector 233 and the pin 235, respectively, the reflector 233 is It is rotated around pin 2 3 5 (Y axis) by applying force by hand or tool. When the hand is released, the reflector 2 33 is held at that angle. Preferably, fine adjustment of the reflection angle is performed by inserting a screwdriver into a groove such as “+” or “one” provided in the head of the reflector 233. Thus, the reflectors 230 to 232 can be set at any angle, and the infrared beams emitted from the remote control 100 have different directions depending on the reflectors 230 to 232. The light is reflected to the remote control signal receivers such as televisions, air conditioners, and lights.

The reflecting plate 233 is made of a plastic material having at least a chrome plating on the reflecting surface, a polished surface of a substance (metal, etc.) that scatters and absorbs little infrared light, a total reflection of a prism, and a mirror. Or a diffraction grating can be used.

FIG. 2 (D) is an enlarged front view of the reflectors 220 to 222 of another embodiment. In the figure, a plurality of protrusions 210 provided on a holder portion 200 have a concave portion 211 on the side surface as shown in the figure, and the concave portion 211 has a concave portion 211 on the reflector ring 222. The reflector ring 2 2 3 rotates around the X axis by fitting the projection Supported as possible. The reflector ring 23 has a support member 224 on the Y-axis orthogonal to the X-axis as shown in the figure, and the reflector 225 is fitted into the support member 224 so that the reflection is achieved. The plate 225 is supported rotatably about the Y axis. In this way, there is an advantage that the reflection position of the reflector becomes constant regardless of the direction in which the infrared beam is emitted. Thus, the infrared beams emitted from the light-emitting diodes 111 to 113 of the remote control 100 are converted into substantially parallel bundles by the lenses 114 to 116, respectively. The light is reflected in different directions by 0 to 222, and is directed to a remote control signal receiving section for a television, an air conditioner, a lighting, etc. FIG. 2 (E) is a rear perspective view of a reflector of still another embodiment. In the figure, one of the non-flexible wire members 227 is adhered to the back surface of the reflection plate 226, and the other of the wire members 227 is fixed to the wall surface of the holder part 200. Thus, when a force is applied to the reflector 222 by hand or tweezers, the wire 227 also bends in a direction corresponding to the force, and when the hand is released, the reflector 222 is held at that angle : According to this configuration, there is an advantage that the cost can be extremely reduced.

FIG. 3 is a block diagram of the holder 200 of the embodiment. In the figure, the proximity sensor 241 has a concave mirror 242 inside the cylindrical member, thereby restricting the field of view to the front part of the holder part 200 and bringing it closer to the holder part 200. Sensitive heat rays from the hands. The silicon interference filter 243 blocks out visible light and provides high sensitivity to wavelengths (infrared rays) near body temperature (36 ° (~ 37 ° C)). For example, it is configured to have a power-on characteristic at a wavelength of about 3 m. A pyroelectric infrared sensor 244 is provided at the focal point of the concave mirror 244, and the infrared sensor 244 outputs a positive signal according to the increase when the incident infrared energy increases. When the infrared energy decreases, a negative signal corresponding to the decrease is output. The detection output of the infrared sensor 244 is input to the AMP 245 via the coupling capacitor C 1, where it is amplified to a signal that swings positively and negatively around about 2.5 V. Roh emissions de-pass filter (BPF) 2 4 6 are to have a high sensitivity to and out motion of the hand within the field of view, having a band pass in the vicinity of example. 1 to 3 H _z. Thus, when the hand is within the field of view of the proximity sensor 241, the comparator (CMP) 247 force is set to 0 N, and the flip-flop (FF) 249 is set. (EL, LED, etc.) Turn on 25 1. This brightens the hand and makes remote control operation easier. When the hand goes out of the field of view of the proximity sensor 241, the comparator 248 force s0K is applied to reset the FF249, and the light emitting element 251 disappears. In addition, make sure that capacitor C2 is reset at power-on by FF249 force s.

An audio signal (including a buzzer sound) sent from an interphone (not shown) is amplified by the AMP 252 and sounds the speaker (SP) 253. On the other hand, when the user presses the “TALK” button 255, the inverted output of the inverter 257 activates the AMP 256 and the speaker's voice from the microphone (MIC) 254 is output. Signal is AM P 2 5 6 Is amplified and sent to the phone.

The DC power supply 300 converts the input AC 100 V into DC + V and supplies it to the holder 2 ◦ 0. The + V of DC is further supplied to the remote control 100 set in the holder unit 200 via the contact type terminal 258, and a nickel-powered nickel battery (not shown) in the remote control 100 is supplied. Charge.

FIG. 4 is a block diagram of the remote controller 100 of the embodiment. In FIG, CPU 1 6 0 _c also CPU 1 6 0 performs main control of the remote control 1 0 0 Ru a clock (CLOCK) function (not shown). R0M140 stores the control programs of FIGS. 6 to 8 executed by the CPU 16◦ and the various address tables of FIG. 5 (A). The RAM I 50 is used by the CPU 160 as a work area and also stores various temporary data shown in FIG. 5 (B). The display (DISP) 120 emits time data or timer data in response to key operations. The key switch (KSW) 130 has keys for timer control in addition to control keys for various remote control. When interrupt input is permitted by the CPU 160, the user inputs an interrupt to the CPU 160 by pressing any key. 16 1 is a common bus of the CPU 160. The interface 162 interfaces the CPU 160 with the remote control signal circuit at the bottom of the drawing.

Here, an example of a conventional wireless remote control signal is shown in FIG. Generally, remote control devices in Japan are PPM (Pulse Position Modulation) method. The PPM method consists of a combination of “representative codes” as shown in the figure, where T is a unit time (500 to 8◦0 S). The form of the representative code varies from company to company, but the `` code signal '' is a form in which the data of `` read '' and `` stop '' are inserted between the code of `` reader '' and `` stop '' as shown in each company . Signal actually emitted from the remote control device is a "code signal" pulse-modulated with a 3 3 KH _{_Z} ~40 KH _Z "modulated signal". However, it is practically difficult to analyze and learn each remote control signal with a different form or modulation frequency, and accurate learning is not possible. Therefore, the remote controller 100 of the embodiment stores and reproduces the “modulated signal” itself. In FIG. 4, when storing the remote control signal of the device, the user presses, for example, the “0N” key of the TV in advance. As a result, an interrupt is input to the CPU 160, and the CPU 160 supplies the address data of the selector corresponding to the “0N” key of the TV to the latch 169. The decoder 170 outputs the decode signals DI and DO for selecting each input line of the selector (SEL) 174 and the selector (SEL) 176 to 178 according to the address data of the latch 169. Is output. In the case of storing a remote control signal, the decoded signal D 0 is not important. Next, when the user presses the “MEM” key 16 3, the AND gates 16 6 and 18 1 are energized, and the decoded signal DI is output to the corresponding selector 17 4. As a result, of the selectors 174, only the selector corresponding to the “0N” key of the TV selects the upper input. other All selectors 1 7 4 select the lower input. Next, press the key corresponding to “TV-0 N” of the remote control device of the device you want to learn, and send the remote control signal to the light-receiving unit (PIN photodiode 117) of the remote control 100. The received signal of the PIN photodiode 117 is amplified by the AMP 171, then passes through a non-pass filter (BPF) 172, further passes through a waveform shaping circuit 173, and outputs a pulse signal ( (Modulated signal in Fig. 9). When the first pulse signal satisfies the AND gate 166, the output is input to the flip-flop (FF) 167 via the OR gate 165. FF 1 6 7 can be set at the next click lock signal CLK (e.g. 8 0 KH ₂ or higher), the output of counter (CNTR) 1 6 8 and shift register (SR) with a 1 7 5 Energize. The shift register 175 has, for example, 6 K bits per channel. Shift register 1 Ί 5 FIF 0 and R AM Good _c shift register 1 7 5 be constituted by instead the modulated signal received freshly for Channel corresponding to "0 N" key of the TV The shift is performed, but the contents of the shift register 175 are circulated for other channels. When the counter 1668 reaches the cycle count value of the shift register 1775, the decode output of the counter 1668 resets FF167 and ends the storage operation. After saving, release the “MEM” key 16 3. When performing the above-described storage operation, the remote control signal light emitting unit 110 is oriented in a direction unrelated to the device.

If you want to send the stored remote control signal to the device, For example, press the "0 N" key on the TV. As a result, an interrupt is input to the CPU 160, and the CPU 160 supplies the address data corresponding to the “ON” key of the TV to the latch 169. Decoder 1 7 〇 is now _c to output decode signal DI, the DO according add-Resude Isseki is important decode signal D 0. As a result, of the selectors 176 to 178, only the selector 176 corresponding to the “ON” key of the TV corresponds to the “0N” key of the TV of the shift register 175 Is selected and output. Next, the CPU 166 outputs a trigger signal, which is input to the flip-flop 167 via the 0R gate 165, and the FF 166 is the next clock signal. Set on CLK, its output activates counter 168, shift register 175, and selector 176-178. This causes the shift register 1775 to cycle through the stored contents of all channels: At the same time, the infrared emitting diode 1 11 emits a remote control signal corresponding to the TV's "◦ ヽ '" key. When the count value of the counter 168 reaches the cycle count value of the shift register 175, the decode output of the counter 168 resets the FF 167 and terminates the transmission operation. Of course, the above remote control signal can be skipped by timer control. Details will be described later.

FIG. 5 (A) is a diagram for explaining an address table of the embodiment. The address table is stored in the ROM 140: In the figure, the timer address table 141 is referred to as “TMA_ _”, where “T \ '1 0 Γ \'” is ΤV Ν ”key, — AC 1 0 N” is AC “0 N” key, “Light— 0 1 \-one is Address data of the selector corresponding to the “0N” key of Light. The key switch address table 1 4 2 is referred to as “KSAT”, where “TV—V 0 L Δ” is the “V◦L Δ” key on the TV and “TV—V 0 L ▽” is the “V 0 L ▽” on the TV. L ▽ ”key,

“TY—CHA” is the TV “CHA” key, and “TV—CHV” is the address data of the selector corresponding to the TV “CHV” key. The same applies to other address data. The key switch group table 144 is referred to by “K S G T”, where data 0, 2, and 4 are stored.

In this embodiment, the correspondence between the control key and the address table is determined as described above. However, in practice, the remote control 100 stores and reproduces the remote control signal of any function of any device as it is. Because it is possible, the meaning of the above control keys can be freely set.

FIG. 5 (B) is a diagram illustrating a software register of the embodiment. The software register is located in RAM1δ0. In the figure, clock register 15 1 is referred to by “CLKR” and stores and updates clock data. Here, (Η) is time data and (Μ) is minute data. _E Display register 152 is referred to by “DSPR” and stores display data of display 120. The timer register 15 3 is referred to as “λλ4R”, where “TV—ON time” is the time data for turning on the TV, and “Γ Υ—OFF time” is the time for turning off the TV. Store the data respectively. The same applies to other time data. You. The flag “F” at the beginning of each time data is set to logic 1 when the time data is used as ON or OFF by the timer by the timer processing routine described later, and the value of the clock register 151 (M ) Is updated to all logic 0s when updated. The various index registers 154 are referenced by "I", "P", "A", and "G", respectively. Evening flag (TMF) 1 56 is set by pressing the “TIMER” key and reset by pressing the “CLOCKJ key”.

FIG. 6 (A) is a flowchart of the main process of the remote controller 100 of the embodiment. When power is turned on to the remote control 100, input is made to this process. In step S1, initial settings (TMF-〇, a1IF-0, etc.) are performed. In step S2, the key switch 130 is enabled to interrupt (INT-EN). In step S3, the index register I for scanning the timer register 153 is cleared, and in step S4, it is determined whether TMF = 1. When TMF = 1, the timer is set, confirmed or updated, so the flow advances to step S6 to set the contents of the timer register 15 3 pointing to the register P to the display register 15 2. If TMF is not 1, the clock mode is set, so the flow advances to step S5 to set the contents of the current time of the clock register 151 to the display register 152.

Step S7 and subsequent steps are a timer processing routine. That, _c to determine whether stearyl Tsu or the contents of the flop S 7 in the clock register 1 5 1 of contents of register I force s fingers to the timer register 1 5 3 equals When CLKR = TMR (I), the timers match, so the flow advances to step S8 to determine whether the flag is 1 or not. If F = 1, the timer data is not used, so the flow advances to step S9, and the timer address table 1441 is read with the contents (I s) of register I shifted down by 1 bit, and the address data is read. Set the latch to latch 169. In step S10, a trigger signal is output. Thus, the remote control signal is emitted from the light emitting section 11 ◦ of the remote control 100 by the timer control. In step S11, 1 is set to the flag. If CLKR is not equal to TMR (I) in step S7 or F = 1 in step S8, the process proceeds to step S12 without emitting a remote control signal. In step S12, +1 is set to register I. In step S13, it is determined whether or not I = 6. If not, the process returns to step S4, and if I = 6, returns to step S3.

FIG. 6 (B) is a flowchart of the clock interrupt processing of the embodiment. When the clock function of CPU 16 ◦ counts 1 minute, it interrupts this process. There are no restrictions on clock interrupts. In step S21, the key switch 130 is set to disable interrupts (INT-DS). In step S22, the hour and minute (H, M) of the clock register are updated. In step S23, all flags F of timer register 15 3 are set to "0". In step S24, the key switch 130 is set to enable interrupts (IN-E-EN).

Fig. 7 (A) is a flowchart of the interrupt processing of each key of "CL0CK", "TIMER", and "SETj". _{g Q}

Press the "CLOCK" key to enter step S31 and set the evening flag 1 56 to 0. Pressing the “TIMER” key inputs the value to step S32 and sets the timer flag 156 to “1”. Also

When the "SET" key is pressed, an input is made to step S33, and it is determined whether or not TMF = 1. When TMF = 1, the timer is in the set mode, so the flow advances to step S34 to set the contents of the display register 152 to the timer register 1553 indicated by the register P. If TMF is not 1, do nothing.

In the figure, in step S41, the key switch 130 is not allowed to interrupt (INT- In step S42, it is determined whether or not TMF is 1. When TMF is not 1, the clock mode is set, so that the flow advances to step S43 to determine the input key, and the determination result ( Key number 0 ~

In step S44, the contents of the key switch address table 14 2 pointed to by register A are read out, and the address data is set in latch 16 9 ₌ slave S 45 outputs a trigger signal . Thus, the remote control signal is manually emitted from the light emitting portion 110 of the remote control 100: When the determination in step S42 is TMF = 1, the timer set mode is set, so that step S42 is performed. 4 Proceed to 7 and enter the key

(Group) Performs the discrimination and sets the discrimination result (group number 0 to 2) in register G. In step S48, it is determined whether or not the current determination group is the same as the previous determination group. In the case of the same group, the keys within the same frame in Fig. 1 (B) (not only the "0N" key, but also the "VOL" key or the "CH" key) are pressed again. Then, the exclusive OR (E0R) of the lower one bit of the register P and data 1 is calculated, and the result is set in the register P. This allows the user to read “TV-ON time” data or “TV-OFF time” data by, for example, pressing the “0N” key of TY repeatedly. If it is determined in step S48 that the grooves are not the same, the flow advances to step S49 to read the contents of the key switch group table 144 indicated by the register G and to store the result (0, 2, or 4) in the register. Set to P. In step S46, key switch 130 is enabled for interrupt (INT-EN).

Fig. 8 (A) is a flowchart of the "H" key interrupt processing. In step S61, it is determined whether or not TMF = 1. When TMF = 1, the flow advances to step S63, and the time data (H) in the display register 152 is incremented by one. When TMF is not 1, the flow advances to step S62, and the time data (H) of the clock register 151 is incremented by one.

When TMF = 1, the flow advances to step S73, and the value of the display register 152 is incremented by one (M). If TMF is not 1, the flow advances to step S72 to increment the minute data (M.) of the clock register 151 by one. FIG. 10 is a diagram showing an example of use of the remote control device of the embodiment. Remote control manually or by timer function

The infrared beam emitted from the sensor 100 is reflected in a predetermined direction by a plurality of reflectors of the holder unit 200, respectively, and is used in a living room, a hospital room, or the like (or a blind, a shirt, etc.) 400, Lights reach 500, TV (or VTR, stereo, etc.) 600, air conditioner 700, door remote lock mechanism 800 and other remote control signal receiving sections. In addition, communication with the interphone 900 can be made via the holder 200.

Elderly and sick people can also send emergency signals from a remote control device installed at the bedside to an emergency warning receiver on the wall.

Further, it is possible to provide a simple reflector adjuster having the same contour as the remote control 100 and capable of emitting a visible light laser beam from the remote control signal light emitting unit 110. According to this reflector adjusting device, since the laser beam is visible, the angle of the reflector can be easily adjusted while visually checking whether or not the laser beam has reached the remote control signal receiving section of the device.

In the above-described embodiment, the remote control signal is transmitted by an infrared beam. However, the present invention is not limited to this. For example, visible light may be used.

In the above-described embodiment, the remote control signal is transmitted from the remote control device to various devices. However, the present invention is not limited to this. For example, a remote control signal light-receiving unit is provided near each of the light-emitting diodes 111 to 113 of the remote-control signal light-emitting unit 110, and remote control signals from various devices (abnormal alarm Signal, etc.) may be received. Even if the infrared beam sent from each device spreads, the angle of each reflector plate 23 corresponds to each device, so that the remote control signal receiver of each device can reliably receive the remote control signal for each device.

As described above, according to the present invention, each beam from a plurality of light emitting elements is guided to each device by a plurality of beam reflectors, so that devices in a room can be reliably controlled with uniform beam power.

Also, since the remote control device of the present invention has a timer control function inside, not only can it be used as a conventional remote control device at hand, but also if a timer is set and placed in a holder, it is possible to concentrate on multiple devices. It becomes a shape control device. Therefore, not only TVs and air conditioners, but also curtains and individual lighting devices can be managed wirelessly with a total timer, and the timer function that previously had to be provided for each device can be omitted. From the point of view, it also has the effect of promoting the transition to home talent.

Also, since the remote control device of the present invention stores the remote control modulation signal in its original form, regardless of the current and future manufacturers, despite the fact that the carrier frequency of the remote control signal varies greatly among manufacturers. It can be learned with high fidelity and easily reproduced even with a remote control signal.

It is evident that a wide variety of embodiments can be constructed without departing from the spirit and scope of the invention, and thus the invention is not limited to any particular embodiment except as limited in the appended claims. Absent.
