That is, thereceiver 42, thefirst pin 43, and thesecond pin 44 are arranged in this order in the direction opposite to the inserting direction. - As shown in
FIG. 5 , the throughhole 45 and the first and second screw holes 46 and 47 are formed in the mountingsurface 41. Specifically, the throughhole 45 and the first and second screw holes 46 and 47 are formed in the reinforcingmember 52 and are exposed to the outside of the mountingportion 40 through the throughholes wall portion 51. - The layout of the through
hole 45 and the screw holes 46 and 47 is not particularly limited. In this embodiment, for example, thesecond screw hole 47 is provided between the first andsecond pins hole 45 and the first and second screw holes 46 and 47 may be provided on the front side or the rear side of the first andsecond pins hole 45 communicates with a screw hole (not shown) of a boss provided on themain base 21. - As shown in
FIGS. 2 and 10 , themain portion 35 of thehinge fixing portion 33 is mounted on the mountingsurface 41 of the mountingportion 40. Themain portion 35 is supported by the mountingsurface 41 from below. The insertingportion 37 is inserted into theinsertion groove 70 and comes into contact with the receivingsurface 75 from below. The insertingportion 37 is supported by thereceiver 42 from the side opposite to the mounting surface 41 (that is, from above). In this way, thefirst hinge 4 connected to thedisplay unit 3 does not fall backward before it is screwed. - As shown in
FIG. 3 , themain portion 35 comprises anelongated hole 81, acircular hole 82, and first to third insertion holes 83, 84, and 85. Theelongated hole 81 is provided at a position corresponding to thefirst pin 43, and thefirst pin 43 engages with theelongated hole 81. For example, theelongated hole 81 includes a pair of arc portions that are away from each other and a substantially straight portion that connects the pair of arc portions. The arc portion may be a semicircle or an arc shorter than the semicircle. The substantially straight portion may be a strict straight line or a line with a small curvature. Theelongated hole 81 is formed such that the width thereof in a specific direction (longitudinal direction) is larger than the width thereof in other directions. - The
elongated hole 81 is elongated in the inserting direction (that is, the front-rear direction) of the insertingportion 37. When thefirst pin 43 engages with theelongated hole 81, the position of thehinge fixing portion 33 in the front-rear direction is adjastable, and the movement of thehinge fixing portion 33 in a direction (that is, the left-right direction) orthogonal to the inserting direction of the insertingportion 37 is regulated. - The
circular hole 82 is provided at a position corresponding to thesecond pin 44, and thesecond pin 44 engages with thecircular hole 82. Thecircular hole 82 has an inside diameter corresponding to the diameter of thesecond pin 44. When thesecond pin 44 engages with thecircular hole 82, the movement of thehinge fixing portion 33 in the front-rear direction and the left-right direction is regulated. - The first to third insertion holes 83, 84, and 85 are provided so as to correspond to the through
hole 45 and the first and second screw holes 46 and 47 and communicate with the throughhole 45 and the first and second screw holes 46 and 47, respectively. Afirst screw 87 passes through thefirst insertion hole 83 and the throughhole 45 and is then engaged with a screw hole (not shown) of themain base 21. First andsecond screws hinge fixing portion 33 is firmly fixed to the mountingportion 40. - As shown in
FIGS. 2 and 3 , thehinge fixing portion 33 comprises apressing portion 91. Thepressing portion 91 faces acable 92 that extends between thedisplay unit 3 and themain unit 2 from above and suppresses thecable 92 from coming off. - Next, the assembly of the electronic apparatus 1 will be described.
- The reinforcing
members 52 are fixed to themain cover 22 before the first andsecond hinges screw portions 62 are fixed by thescrews 64 to position and temporarily fix the reinforcingmembers 52 to themain cover 22. Then, a jig for welding is used to weld and fix the plurality of welding and fixingportions 63 at the same time. In this way, the reinforcingmembers 52 are firmly fixed to themain cover 22. - Meanwhile, the
hinge bracket 32 is fixed to thedisplay unit 3 to connect thehinge rotating portion 31 and thehinge fixing portion 33 to thedisplay unit 3. Then, thehinge fixing portion 33 is fixed to the mountingportion 40 to connect thedisplay unit 3 to themain unit 2. - Specifically, as shown in
FIG. 9 , the insertingportion 37 is obliquely inserted into theinsertion groove 70 from the upper side. Then, themain portion 35 is put down so as to be substantially parallel to the mountingsurface 41 using the inserted insertingportion 37 as a pivot, while rotating the hinge fixing portion 33 (inFIG. 9 , movement in the direction of an arrow A). In this process, first, thefirst pin 43 engages with theelongated hole 81 to temporarily determine the position of thehinge fixing portion 33 in the left-right direction. - Then, the
second pin 44 engages with thecircular hole 82 to determine the position of thehinge fixing portion 33 in the front-rear direction and the left-right direction. In this case, the insertingportion 37 comes into contact with the receivingsurface 75 at the same time as themain portion 35 is mounted on the mountingsurface 41, and the insertingportion 37 is supported by thereceiver 42 from above. - As shown in
FIG. 10 , moment M that allows thedisplay unit 3 to fall backward due to the weight of thedisplay unit 3 is applied to thehinge fixing portion 33. However, since themain portion 35 comes into contact with the mountingsurface 41 and the insertingportion 37 is supported by thereceiver 42 from the upper side, thedisplay unit 3 does not fall. That is, the mountingportion 40 supports thedisplay unit 3 such that thedisplay unit 3 does not fall, without using screws. - For example, the assembler tightens the
first screw 87 into the screw hole of themain base 21 through theinsertion hole 83 and the throughhole 45, without holding thedisplay unit 3 with hands. Then, the assembler tightens the second andthird screws hinge fixing portion 33 is fixed to the mountingportion 40. Then, thehinge cover 94 is attached to themain unit 2. - According to this structure, it is possible to improve the assemblability of the electronic apparatus 1. That is, the inserting
portion 37 inserted into theinsertion groove 70 and supported by thereceiver 42 from the side opposite to the mountingsurface 41 makes it possible to support thedisplay unit 3 so as not to fall, without being screwed. Therefore, the assembler can perform a screwing operation without holding thedisplay unit 3 with hands. This structure improves the assemblability of the electronic apparatus 1. In addition, since the first andsecond pins elongated hole 81, and thecircular hole 82 are used to perform positioning, the assemblability of the electronic apparatus 1 is further improved. - According to the above-mentioned structure, it is possible to perform an assembly process capable of absorbing the tolerance of each component. That is, the main cover, the hinge, and the display unit each have a dimension error (component tolerance) and an assembly error (assembly tolerance) related to manufacturing. For comparison, an electronic apparatus is considered in which a first hinge bracket extending in the display unit, a second hinge bracket extending in the main unit, and a hinge rotating portion are integrated into a hinge assembly.
- In this case, the hinge assembly includes the dimension errors of the first and second hinge brackets and the hinge rotating portion. In addition, the hinge assembly includes assembly errors when the hinge assembly is assembled. When the hinge assembly is connected to the display unit, the dimension error of the hinge assembly is added to the dimension error of the display unit, and an assembly error is additionally involved in the connection. Therefore, a large amount of error is included.
- In addition, the main unit has a dimension error. Therefore, when the hinge assembly connected to the display unit is connected to the main unit, the dimension errors of the display unit and the hinge assembly are added to the dimension error of the main unit, and an assembly error is involved in the connection. Therefore, there is a large amount of error in the electronic apparatus.
- In order to enclose the errors, the hinge assembly is forcibly fixed to the main unit. In this case, stress is likely to be applied to the fixing portion for fixing the hinge assembly. When the display unit is repeatedly opened and closed, the stress applied to the fixing portion may damage the hinge fixing portion.
- Meanwhile, in the structure according to this embodiment, there are the dimension and assembly errors (hereinafter, referred to as the errors of the display unit 3) of the
display unit 3 and thehinge bracket 32 between thedisplay unit 3 and thehinges main cover 22 and the reinforcingmember 52 between themain cover 22 and the reinforcingmember 52. - However, in the structure according to this embodiment, one of two positioning holes is the
circular hole 82, and the other positioning hole is theelongated hole 81. Therefore, thesecond pin 44 engaged with thecircular hole 82 is a standard for positioning, and thefirst pin 43 is naturally engaged with theelongated hole 81 at the position to which the errors are reflected. Therefore, the error of thehinge fixing portion 33 in the front-rear direction is reduced. - It is possible to reduce the error of the
hinge fixing portion 33 in the left-right direction by rotating thehinge fixing portion 33 on the mountingsurface 41 in the left-right direction and utilizing the shape of theelongated hole 81. That is, before thesecond pin 44 engages with to thecircular hole 82, thehinge fixing portion 33 can be slightly inclined in the left-right direction to adjust the position of thehinge fixing portion 33 with respect to thefirst pin 43 according to the shape of theelongated hole 81. In this way, it is possible to adjust the position of thecircular hole 82 with respect to thesecond pin 44 without applying a load to theelongated hole 81 and thefirst pin 43. Therefore, it is possible to naturally fit thesecond pin 44 to thecircular hole 82. As a result, the error of thehinge fixing portion 33 in the left-right direction is reduced. - That is, in this embodiment, it is possible to absorb the error of the
display unit 3 and the error of themain unit 2 between thehinge fixing portion 33 and the mountingportion 40. Therefore, the error which is to be enclosed in thehinge fixing portion 33 is reduced. As a result, little stress is applied to thehinge fixing portion 33, and the reliability of the electronic apparatus 1 is improved. - As shown in
FIG. 9 , when the inclinedhinge fixing portion 33 is rotated toward the mountingsurface 41, theelongated hole 81 elongated in the inserting direction of the insertingportion 37 is less likely to come into contact with thefirst pin 43 than the circular hole. Therefore, it is possible to smoothly attach thehinge fixing portion 33. - When the
receiver 42 deviates from the upper area of the mountingsurface 41 and the space S to which the insertingportion 37 escapes is provided below thereceiver 42, it is possible to obliquely insert the insertingportion 37 into theinsertion groove 70 and rotate the insertedhinge fixing portion 33 to the mountingsurface 41. This structure improves the attachment of thehinge fixing portion 33. - According to the structure in which the first and
second pins hinge fixing portion 33 is rotated to the mountingsurface 41, thehinge fixing portion 33 is less likely to come into contact with the first andsecond pins hinge fixing portion 33 is improved. - The
receiver 42 may be provided in themain housing 6 made of a synthetic resin. When thereceiver 42 is provided in themetal reinforcing member 52, it is possible to form thereceiver 42 with a relatively small size to which a relatively strong force or moment is applied, while maintaining the strength. This contributes to reducing the size and thickness of the electronic apparatus 1. - The screw holes 46 and 47 may be provided in the
main housing 6 made of a synthetic resin. When the screw holes 46 and 47 are provided in the metal reinforcing member, it is easy to ensure the strength of the screw holes 46 and 47 to which a relatively strong force is applied. - The
second pin 44 is not an indispensable component. When thesecond pin 44 engaged with thecircular hole 82 is provided, it is possible to more accurately position thehinge fixing portion 33, as compared to when only thefirst pin 43 engaged with theelongated hole 81 is provided. - The
second pin 44 is arranged on the rear side of thefirst pin 43 in the inserting direction of the insertingportion 37. In this case, when thehinge fixing portion 33 is rotated and attached, it is possible to make theelongated hole 81 correspond to thefirst pin 43 engaged at a relatively large angle and to make thecircular hole 82 correspond to thesecond pin 44 engaged at a relatively small angle. Therefore, it is possible to smoothly fit thesecond pin 44 to thecircular hole 82. - When the
main housing 6 forms at least a part of the mountingsurface 41 and comprises thewall portion 51 interposed between the reinforcingmember 52 and themain portion 35, themain housing 6 is reinforced by thewall portion 51. Therefore, it is not necessary to provide an additional reinforcing portion in themain housing 6. When the reinforcingmember 52 comprises the supportingportion 66 that supports thewall portion 51 from below and theconvex portion 67 that is higher than the supportingportion 66 and forms a part of the mountingsurface 41, theconvex portion 67 functions as a beam. Therefore, it is possible to increase the strength of the reinforcingmember 52. - For comparison, an electronic apparatus is considered in which a hinge bracket, which is a portion of the hinge assembly, is attached to the main unit. In the electronic apparatus, the hinge bracket connected to the
display unit 3 is inserted into the opening of the main housing and is fixed. Therefore, the display unit is an obstacle to welding and fixation and makes it difficult to weld and fix the hinge bracket. In addition, the size or shape of the hinge bracket is limited by the size of the opening of the main housing. - In the structure according to this embodiment, the first and
second hinges main unit 2. Therefore, it is possible to fix the reinforcingmember 52 to the inner surface of themain cover 22 independently from the attachment of the first andsecond hinges member 52 and the size or shape thereof is hardly limited. The welding and fixation process makes it easy to reduce costs and the number of processes, as compared to a screwing process. - Next, an electronic apparatus 1 according to a second embodiment will be described with reference to
FIG. 11 . In the second embodiment, components having the same or similar functions as those in the first embodiment are denoted by the same reference numerals and a description thereof will be omitted. The second embodiment is similar to the first embodiment except for the following structure. - The electronic apparatus 1 according to this embodiment comprises a relatively
large keyboard 11 including a ten-key (i.e., a numerical keypad). Therefore, as shown inFIG. 11 , the electronic apparatus 1 comprises akeyboard mounting portion 12 with a width close to the overall width of themain cover 22. The size of the reinforcingmember 52 is smaller than that in the first embodiment, and is provided on the rear side of thekeyboard mounting portion 12. - A
metal sheet 101 for reinforcement is connected to the reinforcingmember 52. Thekeyboard mounting portion 12 is recessed to themain housing 6. Themetal sheet 101 is formed with a thickness smaller than that of the reinforcingmember 52 so as to correspond to the recess of thekeyboard mounting portion 12. Themetal sheet 101 is attached to the lower side of thekeyboard mounting portion 12 along the side end portion of themain cover 22. Themetal sheet 101 reinforces thekeyboard mounting portion 12. - According to the above-mentioned structure, similar to the first embodiment, it is possible to improve the assemblability of the electronic apparatus 1. According to the above-mentioned structure, the shapes of the reinforcing
member 52 and themain cover 22 of the electronic apparatus 1 according to this embodiment are different from those of the electronic apparatus 1 according to the first embodiment, but the electronic apparatuses 1 according to the first and second embodiments have other common parts. According to the electronic apparatus 1, it is possible to relatively simplify customization such as of the type of thekeyboard 11. - The electronic apparatuses 1 according to the first and second embodiments have been described above, but the invention is not limited thereto. The components according to the first and second embodiments may be appropriately combined with each other. The invention is not limited to the above-described embodiments, but various modifications and changes of the invention can be made without departing from the scope and spirit of the invention.
