Summary of the Invention

Problems to be Solved by the Invention

[0004] Since the push buttons are resin molded products, it is necessary to prepare different molds for forming the boss portion on the front surface of the central push button. Since the number of parts increases, it is also disadvantageous in terms of management cost.

[0005] An object of the present invention is to provide a remote controller capable of reducing the number of parts and achieving cost reduction.

Means for Solving the Problems

[0006] The remote control according to claim 1 comprises a plurality of push buttons, a case body having a switch and a light-emitting part on the front side for each of the plurality of push buttons, and a cover case attached to the front side of the case body and supporting the plurality of push buttons on the front side, wherein the cover case has a mounting part provided for each of the push buttons corresponding to the switch and mounted so that the push button moves in the front-rear direction, the mounting part is provided at a position facing the switch and has a first mounting side hole that penetrates in the front-rear direction, and is provided at a position facing the light-emitting part, The mounting portion comprises a second mounting side hole portion that penetrates in the rearward direction, and a light guide portion is provided between the mounting portion and the push button, at a position facing the light-emitting portion and the second mounting side hole portion, which is light-transmitting and guides light from the light-emitting portion forward, and the push button is provided at a position facing the light guide portion and comprises a button side hole portion that penetrates in the front-rear direction and a contact portion provided on the rear surface that contacts the switch via the first mounting side hole portion, and the first light guide portion, which is the light guide portion provided between a predetermined first push button among the plurality of push buttons and the mounting portion, protrudes rearward, and 2nd The device comprises a first rear light guide portion inserted into the mounting side hole and a first front light guide portion protruding forward, the first front light guide portion comprising an insertion portion inserted into the button side hole and a protruding portion that protrudes forward from the front surface of the push button, and the second light guide portion, which is the light guide portion provided between the mounting portion and a second push button different from the first push button among the plurality of push buttons, protrudes rearward, 2nd The device is characterized by comprising a second rear light guide portion that is inserted into the mounting side hole, and a second front light guide portion that protrudes forward and is inserted into the button side hole, with its front end not protruding further forward than the front surface of the push button.

[0007] Between the mounting portion and the push button of the remote control according to claim 2, a sheet-like elastic member is arranged to bias the push button forward, the elastic member is provided at a position opposite the first mounting side hole portion and comprises an elastic side hole portion that penetrates in the front-rear direction and a light guide portion, and the contact portion of the push button may contact the switch via the first mounting side hole portion and the elastic side hole portion. [Effects of the Invention]

[0008] According to the remote control of claim 1, in the case of the first push button among the multiple push buttons, the protruding portion of the first front light guide portion of the first light guide portion is made to protrude further forward than the front surface of the first push button, and this protruding portion functions as a tactile guide, thereby allowing the first push button to be distinguished from the second push button. This makes it possible to perfectly match the shapes of the first push button and the second push button without directly providing a protrusion on the first push button. Therefore, the molds for mass-producing the push buttons can be standardized and the number of parts can be reduced, thus reducing manufacturing and management costs. In addition, since a part of the first light guide portion also serves as a tactile guide, the cost of providing a tactile guide on the push button can be reduced.

[0009] According to the remote control of claim 2, when a push button is pressed, the impact from the switch can be absorbed and mitigated by the elastic member. Furthermore, since the elastic member can be incorporated into the cover case and unitized, the assembly process can be simplified. An example of a switch is a tact switch.

Cylindrical pins 933 and 934 are provided on the upper and lower left sides of the central light guide 98. Cylindrical pins 935 and 936 are provided on the upper and lower left sides of the right light guide 99. These pins 931 to 939 are solid.

[0040] As shown in Figure 6, an edge 911 is provided on the left side of the upper end of the elastic sheet 9, an edge 912 is provided in the center of the upper end, and an edge 913 is provided on the right side of the upper end. These edges 911 to 913 are cut out to form a roughly U-shape when viewed from the front. An edge 914 is provided at the lower left corner of the elastic sheet 9, and an edge 917 is provided at the lower right corner. Edges 914 and 917 are cut out to form a roughly inverted L-shape when viewed from the front. An edge 915 is provided to the left of the center of the lower end of the elastic sheet 9, and an edge 916 is provided to the right of the center of the lower end. Edges 915 and 916 are cut out to form a roughly inverted U-shape when viewed from the front.

[0041] Furthermore, the elastic sheet 9 with the above configuration is preferably coated in black in all parts except for the left light guide portion 97, the central light guide portion 98, and the right light guide portion 99. In other words, the left light guide portion 97, the central light guide portion 98, and the right light guide portion 99 are transparent and have the property of transmitting light, while the other parts are black and have the property of not transmitting light. Thus, the elastic sheet 9 can transmit light from LEDs 31-33 forward in the left light guide portion 97, the central light guide portion 98, and the right light guide portion 99, while preventing that light from leaking to the surroundings.

[0042] Referring to Figures 4 and 5, the shapes of the push buttons 11 to 13 will be described. Note that the structure of the push buttons 11 to 13 is the same except for the characters printed on the front, so in this embodiment, the shape of push button 11 will be described in detail. As shown in Figure 4, push button 11 is a roughly rectangular resin plate member that is long in the left-right direction when viewed from the front. A rectangular hole 113 is provided on the left front side of push button 11 and passes through the push button 11 in the front-to-back direction. The characters "Oidaki" are printed to the right of the hole 113.

[0043] As shown in Figure 5, on the rear surface of the push button 11, a pair of protrusions 111 and 112 are provided, aligned horizontally, approximately in the middle of the vertical direction. The protrusions 111 and 112 project backward from the rear surface of the push button 11, forming a roughly cross shape when viewed from the rear. A rib 117 is provided between the protrusions 111 and 112. The rib 117 extends linearly horizontally between the protrusions 111 and 112, and projects backward from the rear surface of the push button 11. The height of the rib 117 is lower than the height of the protrusions 111 and 112.

[0044] An upper projection 114 is provided slightly below the upper end of the rear surface of the push button 11 and in the center in the left-right direction. The upper projection 114 has a leg portion 14A and a locking portion 14B. The leg portion 14A is a straight line extending in the left-right direction when viewed from the rear and protrudes rearward from the rear surface of the push button 11. The locking portion 14B is provided at the rear end of the leg portion 14A and is roughly triangular in side view and protrudes upward. A lower projection 115 is provided at the lower left corner of the rear surface of the push button 11. The lower projection 115 has a leg portion 15A and a locking portion 15B. The leg portion 15A protrudes rearward from the rear surface of the push button 11. The locking portion 15B is provided at the rear end of the leg portion 15A and is roughly triangular in side view and protrudes downward. A lower projection 116 is provided at the lower right corner of the rear surface of the push button 11. The lower projection 116 comprises a leg portion 16A and a locking portion 16B. The leg portion 16A protrudes rearward from the rear surface of the push button 11. The locking portion 16B is provided at the rear end of the leg portion 16A and, in side view, is approximately triangular in shape and protrudes downward.

[0045] A reinforcing rib 118 is provided in a straight line at the lower end of the rear surface of the push button 11, protruding rearward. A reinforcing rib 119 is provided at the upper end of the rear surface of the push button 11, excluding the central part in the left-right direction, and protruding rearward.

[0046] Although not described in detail here, the push button 12, like the push button 11, has a rectangular hole 123 on its front left side. The word "Automatic" is printed to the right of the hole 123. As shown in Figure 5, the rear side of the push button 12, like the push button 11, has a pair of protrusions 121, 122, a rib 127, an upper projection 124, lower projections 125, 126, and reinforcing ribs 128, 129. The push button 13, like the push buttons 11 and 12, also has a rectangular hole 133 on its front left side. The word "Priority" is printed to the right of the hole 133. The rear side of the push button 13, like the push button 11, has a pair of protrusions 131, 132, a rib 137, an upper projection 134, lower projections 135, 136, and reinforcing ribs 138, 139.

[0047] Referring to Figure 2, the shape of the lid cover 10 will be described. The lid cover 10 is roughly rectangular in front view. An edge portion 101 is provided in the central part of the lid cover 10, excluding both the left and right sides of the upper end. The edge portion 101 is cut out to form a roughly U-shape in front view. The length of the edge portion 101 in the left-right direction is such that the push buttons 11-13, which are arranged side by side, can be placed inside. A metal plate 103 is embedded in the upper left part of the lid cover 10, and a metal plate 104 is embedded in the upper right part. The lower end of the lid cover 10 is pivotally supported by pivot supports 631 and 632 on the lower front of the cover case 8, making it possible to open and close it. When the lid cover 10 is closed, the metal plates 103 and 104 face the magnets 701 and 702 of the cover case 8. As a result, the lid cover 10 is attracted by the magnetic force of the magnets 701 and 702, and its closed position is maintained.

[0048] The assembly process of the remote control 1 will be explained with reference to Figures 2, 9, and 10. In this embodiment, for the sake of explanation, the lid cover 10 is omitted in Figures 9 and 10. The case body 3 is best assembled as a single unit beforehand. As shown in Figures 2 and 9, the worker attaches the elastic sheet 9 to the front of the mounting portion 62 of the cover case 8 from the front. At this time, the protrusions 902, 904, and 906 provided on the rear surface 9B of the elastic sheet 9 are fitted into the grooves 77, 78, and 79 provided in the mounting portion 62. Furthermore, the pins 931 to 936 provided on the rear surface 9B of the elastic sheet 9 are fitted into the holes 84 to 89 provided in the mounting portion 62. Furthermore, the rear light guide portion 972 of the left light guide portion 97, the rear light guide portion 982 of the central light guide portion 98, and the rear light guide portion 992 of the right light guide portion 99 are fitted into the rectangular holes 81 to 83 provided in the mounting portion 62. As a result, as shown in Figure 9, the elastic sheet 9 is positioned in a predetermined location within the mounting section 62.

[0049] With the elastic sheet 9 positioned on the mounting portion 62, the rear surface 9B of the elastic sheet 9 is in close contact with the front surface of the mounting portion 62. Each of the circular holes 91 to 96 provided in the elastic sheet 9 faces each of the circular holes 71 to 76 provided in the mounting portion 62. When the cover case 8 is viewed from the front in this state, the locking holes 801 to 803 provided in the mounting portion 62 are exposed on the inside of the upper edge portions 911 to 913 of the elastic sheet 9. The locking holes 804 to 807 provided in the mounting portion 62 are exposed on the inside of the lower edge portions 914 to 917 of the elastic sheet 9.

[0050] Next, as shown in Figure 9, the push buttons 11 to 13 are sequentially assembled to the mounting portion 62 of the cover case 8 to which the elastic sheet 9 is assembled. To assemble the push button 11, the upper projection 114 provided on the upper end of the rear surface of the push button 11 is inserted into the locking hole 801 provided in the mounting portion 62, and the lower projections 115 and 116 provided on the lower end of the rear surface of the push button 11 are inserted into the locking holes 804 and 805 provided in the mounting portion 62.

[0051] Here, the legs 14A of the upper projection 114, the legs 16A of the lower projection 116, and the legs 15A of the lower projection 115 are longer than the plate thickness of the mounting portion 62. This allows the push button 11 to move forward from the front surface of the mounting portion 62 by a predetermined stroke. When the push button 11 has moved to its maximum extent from the front surface of the mounting portion 62, the locking portion 14B of the upper projection 114 locks against the inner edge of the locking hole 801 from the rear. The locking portion 15B of the lower projection 115 locks against the inner edge of the locking hole 804 from the rear. The locking portion 16B of the lower projection 116 locks against the inner edge of the locking hole 805 from the rear. As a result, the upper projection 114 and the lower projections 115 and 116 cannot be dislodged forward from the locking holes 801, 804, and 805, thus preventing the push button 11 from coming off the mounting part 62 of the remote control 1.

[0052] Then, as described above, by assembling the push button 11 to the mounting portion 62, a pair of protrusions 111 and 112 protruding from the rear surface of the push button 11 are inserted from the front into the round holes 71 and 72 of the mounting portion 62 via the round holes 91 and 92 of the elastic sheet 9. At this time, the front light guide portion 971 of the left light guide portion 97 of the elastic sheet 9 is fitted into the hole 113 of the push button 11. The rear surface of the peripheral edge of the hole 113 of the push button 11 engages with the outer circumference of the front surface of the base portion 973, which is formed to surround the base end of the front light guide portion 971. Furthermore, the right side of the rear surface of the push button 11 comes into contact with a pair of contact portions 921 and 922 provided on the front surface 9A of the elastic sheet 9.

[0053] Here, the base portion 973 and contact portions 921, 922 of the elastic sheet 9 contact positions on both the left and right sides of the rear surface of the push button 11. Since the heights of the contact portions 921, 922 and the base portion 973 are the same, the rear surface of the push button 11 contacts these contact portions 921, 922 and the base portion 973 in parallel. As a result, the push button 11 can be assembled parallel and evenly to the front surface of the mounting portion 62 with the elastic sheet 9 in between.

[0054] Next, the push button 12 is assembled in the same way as the push button 11. The upper projection 124 provided on the upper end of the rear surface of the push button 12 is inserted into the locking hole 802 provided in the mounting part 62, and the lower projections 115 and 116 provided on the lower end of the rear surface of the push button 12 are inserted into the locking holes 804 and 805 provided in the mounting part 62. As a result, the pair of projections 121 and 122 protruding from the rear surface of the push button 12 are inserted from the front into the round holes 73 and 74 of the mounting part 62 via the round holes 93 and 94 of the elastic sheet 9.

[0055] The front light guide portion 981 of the central light guide portion 98 of the elastic sheet 9 is fitted into the hole 123 of the push button 12. The rear surface of the peripheral edge of the hole 123 of the push button 12 engages with the outer circumference of the front surface of the base portion 983, which is formed to surround the base end of the front light guide portion 981. At this time, the protruding portion 98B of the front light guide portion 981 protrudes forward from the inside of the hole 123, beyond the front surface of the push button 12. Furthermore, the right side of the rear surface of the push button 12 comes into contact with a pair of contact portions 923 and 924 provided on the front surface 9A of the elastic sheet 9. As a result, the push button 12 can be assembled parallel and evenly to the front surface of the mounting portion 62 with the elastic sheet 9 in between.

[0056] Next, the push button 13 is attached in the same manner as push buttons 11 and 12. The upper projection 134 provided on the upper end of the rear surface of the push button 13 is inserted into the locking hole 803 provided in the mounting part 62, and the lower projections 135 and 136 provided on the lower end of the rear surface of the push button 13 are inserted into the locking holes 806 and 807 provided in the mounting part 62. As a result, the pair of projections 131 and 132 protruding from the rear surface of the push button 13 are inserted from the front into the round holes 75 and 76 of the mounting part 62 via the round holes 95 and 96 of the elastic sheet 9.

[0057] The front light guide portion 991 of the right light guide portion 99 of the elastic sheet 9 is fitted into the hole 133 of the push button 13. At this time, the rear surface of the peripheral edge of the hole 133 of the push button 13 engages with the outer circumference of the front surface of the base portion 993, which is formed to surround the base end of the front light guide portion 991. Furthermore, the right side of the rear surface of the push button 13 comes into contact with a pair of contact portions 925 and 926 provided on the front surface 9A of the elastic sheet 9. As a result, the push button 13 is mounted parallel to the front surface of the mounting portion 62 without bias, with the elastic sheet 9 sandwiched in between. In this way, as shown in Figure 10, the three push buttons 11 to 13 are assembled in parallel to the mounting portion 62 of the cover case 8.

[0058] Next, the worker attaches the cover case 8, which has the elastic sheet 9 and push buttons 11-13 assembled, to the front of the case body 3. Since the cover case 8, elastic sheet 9, and push buttons 11-13 can be assembled together as a single unit to the case body 3, work efficiency can be improved.

[0059] When assembling the cover case 8 to the front of the case body 3, the window portion 56 of the case body 3 is inserted from the rear into the upper opening 611 of the cover case 8. At this time, the round holes 71-76 of the mounting portion 62 are positioned opposite the switch holes 41-46 on the front of the case body 3. The operating portion 57, which is provided on the lower front of the case body 3, is positioned inside the opening 64 of the lower frame portion 63 of the cover case 8. In this way, the assembly process of the remote control 1 is completed.

[0060] As shown in Figures 10 and 11, in the internal structure of the remote control 1, the respective tips of the protrusions 111 and 112 on the rear surface of the push button 11 contact the switches 21 and 22 on the circuit board 6 via the round holes 91 and 92 in the elastic sheet 9, the round holes 71 and 72 in the mounting part 62, and the switch holes 41 and 42 in the case body 3. Similarly, the respective tips of the protrusions 121 and 122 on the rear surface of the push button 12 contact the switches 23 and 24 on the circuit board 6 via the round holes 93 and 94 in the elastic sheet 9, the round holes 73 and 74 in the mounting part 62, and the switch holes 43 and 44 in the case body 3. Furthermore, the respective tips of the protrusions 131 and 132 on the rear surface of the push button 13 contact the switches 25 and 26 on the circuit board 6 via the round holes 95 and 96 in the elastic sheet 9, the round holes 75 and 76 in the mounting part 62, and the switch holes 45 and 46 in the case body 3. In this state, the elastic sheet 9 sandwiched between the mounting part 62 and the push buttons 11 to 13 constantly biases the push buttons 11 to 13 forward.

[0061] As described above, according to the remote control 1 of this embodiment, as shown in Figures 10 and 11, the front end surface of the front light guide portion 971 of the left light guide portion 97 provided on the elastic sheet 9 is positioned flush with the front surface of the push button 11 inside the hole 113 of the push button 11 located on the left side of the remote control 1. Similarly, inside the hole 133 of the push button 13 located on the right side of the remote control 1, the front end surface of the front light guide portion 991 of the right light guide portion 99 provided on the elastic sheet 9 is positioned flush with the front surface of the push button 13. In contrast to these, in the case of push button 12, the protruding portion 98B of the front light guide portion 981 of the central light guide portion 98 provided on the elastic sheet 9 protrudes forward from the inside of the hole 123, beyond the front surface of the push button 12. By using this protruding portion 98B as a guide, the push button 12 can be easily distinguished from push buttons 11 and 13. Furthermore, the shapes of the push buttons 11-13 can be made perfectly identical without directly providing a protrusion on the front surface of the push button 12. Therefore, the molds for mass-producing the push buttons 11-13 can be standardized, reducing the number of parts and thus lowering manufacturing and management costs. In addition, since a part of the central light guide 98 also serves as a grip, the cost of providing a grip on the push button 12 can be reduced.

[0062] Furthermore, an elastic sheet 9 is sandwiched between the mounting portion 62 of the cover case 8 and the push buttons 11-13. The protrusions 111 and 112 on the rear surface of the push buttons 11 contact the switches 21 and 22 on the front side of the case body 3 via the round holes 71 and 72 in the mounting portion 62 and the round holes 91 and 92 in the elastic sheet 9. As a result, when a push button 11 is pressed, for example, the impact transmitted from the switches 21 and 22 on the circuit board 6 to the fingertip can be absorbed and mitigated by the elastic force of the elastic sheet 9. Therefore, the remote control 1 can improve the click feel (operation feel) when a push button 11 is pressed. In addition, as described above, the elastic sheet 9 and the push buttons 11-13 can be integrally assembled into a unit with the cover case 8, which simplifies and improves the efficiency of the assembly process.

[0063] Furthermore, rectangular holes 81 to 83 are provided in the mounting section 62 at positions opposite to the holes 113, 123, and 133 of the push buttons 11 to 13, respectively. On the other hand, the elastic sheet 9 is directly provided with a left light guide section 97, a central light guide section 98, and a right light guide section 99, and the rear ends of these sections, the rear light guide sections 972, 982, and 992, are inserted and fixed into the rectangular holes 81 to 83. Then, the front ends of the left light guide section 97, the central light guide section 98, and the right light guide section 99, respectively, the front light guide sections 971, 981, and 991, are inserted and fixed into the holes 113, 123, and 133 of the push buttons 11 to 13. In this way, the remote control 1 can reliably guide the light from LEDs 31-33 to the push buttons 11-13 through the left light guide section 97, the central light guide section 98, and the right light guide section 99.

[0064] Furthermore, the mounting portion 62 provided on the cover case 8 is formed to extend in the left-right direction, and three push buttons 11-13 are mounted side-by-side on its front surface. In this configuration, magnets 591 and 592 are embedded in the portion of the front panel 7 of the case body 3 corresponding to the mounting portion 62, and metal plates 771 and 772 are embedded in the mounting portion 62 at positions corresponding to the magnets 591 and 592. This allows the mounting portion 62 to be magnetically attached to the front panel 7, preventing it from floating away from the front panel 7. This prevents the aesthetic appearance from being compromised and allows light from LEDs 31-33 to be more reliably guided to the push buttons 11-13.

[0065] Furthermore, holes 84-89 are provided in the mounting section 62, into which pins 931-936 provided on the rear surface 9B of the elastic sheet 9 are fitted. In addition, ribs 117, 127, and 137 are provided on the rear surface of each of the push buttons 11-13, and are fitted into grooves 901, 903, and 905 provided on the front surface of the elastic sheet 9. This prevents the positions of the left light guide section 97, the central light guide section 98, and the right light guide section 99 from shifting when the push buttons 11-13 are pressed, and ensures that the light from the LEDs 31-33 is guided more reliably to the push buttons 11-13.

[0066] Furthermore, the left light guide 97, the central light guide 98, and the right light guide 99 are each positioned to the left of the push buttons 11-13. Contact portions 921-926 are provided on the elastic sheet 9 to the right of the push buttons 11-13. The contact portions 921-926 protrude forward and contact the rear surface of each of the push buttons 11-13. This allows the push buttons 11-13 to be uniformly supported from the rear in the left-right direction, preventing the push buttons 11-13 from being misaligned or causing discomfort during operation.

[0067] Although I will omit the explanation, it is preferable to adopt an assembly structure that includes an elastic sheet, similar to that used for buttons 11-13, for push buttons 14 and 15. This will reduce the click feeling when pressing push buttons 14 and 15, just as it does for buttons 11-13.

[0068] In the above description, push buttons 11 to 15 are examples of the "push buttons" of the present invention. The central push button 12 is an example of the "first push button" of the present invention, and push buttons 11 and 13 are examples of the "second push buttons" of the present invention. The round holes 71 to 76 of the mounting portion 62 are examples of the "first mounting side holes" of the present invention. The rectangular holes 81 to 83 of the mounting portion 62 are examples of the "second mounting side holes" of the present invention. The holes 113, 123, and 133 of the push buttons 11 to 13 are examples of the "button side holes" of the present invention. The protruding portions 111, 112, 121, 122, 131, and 132 of the push buttons 11 to 13 are examples of the "contact portions" of the present invention. The central light guide portion 98 of the elastic sheet 9 is an example of the "first light guide portion" of the present invention, and the left light guide portion 97 and the right light guide portion 99 are examples of the "second light guide portion" of the present invention. The elastic sheet 9 is an example of the "elastic member" of the present invention. The round holes 91 to 96 of the elastic sheet 9 are an example of the "elastic side holes" of the present invention. The LEDs 31 to 33 of the circuit board 6 are an example of the "light-emitting part" of the present invention.

[0069] It should be noted that the present invention is not limited to the above embodiments, and various modifications are possible. Remote control 1 is a remote controller for remotely operating a gas appliance (e.g., a water heater), but the present invention can also be applied to remote controls for other uses. For example, remote control 1 is a bathroom remote control, but it may also be a kitchen remote control. Remote control 1 is a roughly rectangular shape that is long in the left-right direction when viewed from the front, but it may have other shapes.

[0070] In the above embodiment, a protrusion 98B is formed on the front light guide portion 981 of the central light guide portion 98 of the elastic sheet 9, and this protrusion 98B is made to protrude forward from the hole 123 of the push button 12. For example, instead of the central light guide portion 98, a protrusion may be formed on the front light guide portion of the left light guide portion 97 or the right light guide portion 98, and this protrusion may be made to protrude forward from the hole 113 or 123 of the push button 11 or 13.

[0071] The front of the remote control 1 is provided with five push buttons 11-15, but the number, shape, and arrangement of the push buttons are not limited to the above embodiment. For example, three push buttons 11-13 are provided below the window section 56, but there may be one or three or more. The push buttons 11-13 are not arranged horizontally, but may be arranged vertically or diagonally. For example, the position of the window section 56 may be moved downward, and the push buttons 11-13 may be placed above the window section 56. They may also be arranged vertically to the left or right of the window section 56. The liquid crystal 36 on the circuit board 6 may be omitted.

[0072] The case body 3 of the remote control 1 has a circuit board 6 fixed to the front of the rear case, and a front panel 7 fixed to cover the front of the circuit board 6. However, the front panel 7 may be omitted, for example. In this embodiment, since the remote control 1 is a bathroom remote control, it is preferable to fix the front panel 7 from the viewpoint of waterproofing the circuit board 6.

[0073] A pair of protrusions 111 and 112 are provided on the rear surface of the push button 11, so as to contact and press a corresponding pair of switches 21 and 22 on the circuit board 6. The number of protrusions should correspond to the number of switches to be pressed, so there may be two or more pairs, or even just one. The positions of the protrusions 111 and 112 do not have to be on both the left and right sides of the push button 11, but to evenly distribute the force applied to the push button 11 when pressed, positions on both the left and right sides of the push button 11 are preferable.

[0074] The elastic sheet 9 has a left light guide portion 97, a central light guide portion 98, and a right light guide portion 99 integrally formed from the same material, but these may be provided as separate components. If the circuit board 6 does not have LEDs 31-35, they may be omitted. If omitted, the elastic sheet 9 does not need to be transparent. Also, LEDs 31-35 are just one example of the "light-emitting portion" of the present invention, and may be light bulbs such as lamps.

[0075] The left light guide portion 97 of the elastic sheet 9 includes a front light guide portion 971, a rear light guide portion 972, and a base portion 973, but these may be omitted and the left light guide portion 97 may be formed on the same plane as the front and rear surfaces of the elastic sheet 9. The same applies to the central light guide portion 98 and the right light guide portion 99. For example, in an elastic sheet 9 coated in black, the portions of the left light guide portion 97, central light guide portion 98, and right light guide portion 99, which are formed on the same plane, may be made transparent.

[0076] Magnets 591 and 592 are embedded in the part of the front panel 7 of the case body 3 that corresponds to the mounting part 62, and metal plates 771 and 772 are embedded in the mounting part 62 at positions corresponding to the magnets 591 and 592.
