The input unit 7 includes a front panel 8 bonded to the front surface of the first housing 3, and a plurality of push buttons 9 (operation members) protruding forward through a plurality of openings 8 a formed in the front panel 8. Is provided. For example, in this embodiment, five push buttons 9 arranged at predetermined intervals in the left-right direction are arranged in the input unit 7.

  As shown in FIG. 2, a plurality of push switches 10 (switches) are mounted on the substrate 5 so as to correspond to the positions of the push buttons 9. When the push button 9 is pressed, the corresponding push switch 10 on the substrate 5 is pressed, and a predetermined function is executed. Further, light emitting elements 11 for illuminating the push buttons 9 from the inside of the housing 2 are mounted in the vicinity of the push switches 10 on the substrate 5.

  3 is a cross-sectional view taken along the line AA in FIG.

  As shown in this figure, the push button 9 is integrally provided with a key top portion 9 a that is pressed and a flange portion 9 b that engages with the back side of the front panel 8 and prevents the push button 9 from being pulled out. . A gap for allowing the pressing operation of the push button 9 is secured between the front panel 8 and the push button 9, and water may enter the inside of the front panel 8 through this gap.

  The first housing 3 includes a plurality of openings 3 a that form a space between the push button 9 and the push switch 10. In these openings 3 a, pushers 12 that are pressed according to the pressing operation of the push button 9 and press the corresponding press switch 10 on the substrate 5 are arranged. The pusher 12 has a shape in which the pressing switch 10 side has a smaller diameter than the push button 9 side, and is integrally fixed to the back side of the push button 9.

  In the portable electronic device 1 configured in this way, water that has entered the inside of the front panel 8 from the gap between the front panel 8 and the push button 9 passes through the opening 3a of the first housing 3 and the substrate 5 or the like. In order to prevent the pressing switch 10 from being reached, a waterproof structure using packing is required.

  In the portable electronic device 1 of this embodiment, the push button 9 and the packing are used as separate parts to obtain a good feeling of operation, and the packing shape is simplified to reduce the cost. Therefore, in the portable electronic device 1 of the present embodiment, a sheet-like sheet member 13 is used as a packing for waterproofing the inside of the housing 2 in which the substrate 5 and the press switch 10 are arranged. For example, a resin sheet such as a polyurethane sheet or a PET sheet, or a breathable waterproof sheet such as Gore-Tex (registered trademark) can be used as the packing.

  As shown in FIG. 3, the sheet member 13 is disposed along the inner surface of the first housing 3 so as to close the opening 3 a and is sandwiched between the pusher 12 and the push switch 10. A fixing member 14 is provided between the sheet member 13 and the inner surface of the first housing 3, and the end portion of the surface of the sheet member 13 on the side of the pusher 12 is located through the fixing member 14 of the first housing 3. Fixed to the inner surface. For example, the fixing member 14 can be configured using a waterproof adhesive or a tape coated with a waterproof adhesive, and the latter is used in this embodiment. If it does in this way, the board | substrate 5 and the press switch 10 can be waterproofed using the sheet | seat member 13. FIG. In addition, according to such a waterproof structure, even when a plurality of push buttons 9 are provided, a plurality of push buttons can be formed with a single sheet member 13 without providing packing for each push button 9 as in the prior art. The opening 3a corresponding to 9 can be covered.

  The sheet member 13 preferably has a protrusion 13 a that is formed corresponding to the position where the pusher 12 comes into contact with the pressing switch 10. For example, in the present embodiment, the protrusion 13 a that contacts the center position of the pressing switch 10 is integrally formed on the surface of the sheet member 13 on the pressing switch 10 side. In this way, regardless of the displacement of the pusher 12 due to the backlash of the push button 9, the center position of the push switch 10 is favorably pressed through the protrusion 13a of the sheet member 13, and the push switch 10 is turned on well. It can be operated.

  Further, the push button 9, the pusher 12, and the sheet member 13 are all translucent, and the push button 9 is moved from the inside by the light of the light emitting element 11 mounted in the vicinity of the push switch 10 on the substrate 5. Illuminated. And in the portable electronic device 1 of this embodiment, since the sheet | seat member 13 is used as packing of the input part 7, translucency can be improved compared with the packing of the conventional complicated shape. By adopting such a configuration, in the present embodiment, it is possible to increase the illumination brightness to the inside of the push button 9.

  When the push button 9 is illuminated from the inside, it is preferable to provide the light shielding member 15 so that the light from the light emitting element 11 does not leak to the surroundings and have an adverse effect. In the present embodiment, a light shielding member 15 extending from the sheet member 13 toward the substrate 5 is provided. The light shielding member 15 is formed so as to surround a mounting area on the substrate 5 where the pressing switch 10 and the light emitting element 11 are arranged, and prevents the light from the light emitting element 11 from leaking outside the mounting area. Is radiated to the outside through the sheet member 13, the pusher 12 and the push button 9.

  Next, a configuration useful when a plurality of push buttons 9 are provided in the input unit 7 will be described with reference to FIGS. 3 and 4.

  FIG. 4 is a view showing a sheet member and a light shielding member of the portable electronic device according to the present embodiment, and is a perspective view of the lower part of the first housing as seen from the back side.

  As shown in this figure, in the portable electronic device 1, when a plurality of push switches 10, push buttons 9, and pushers 12 are provided, a plurality of light emitting elements 11 and light shielding members 15 correspond to each of the plurality of push switches 10. The light shielding member 15 is provided so that the light from the light emitting element 11 does not leak into a region where the pressure switch 10 different from the pressure switch 10 corresponding to the light emitting element 11 is disposed. Thereby, it becomes possible to radiate light by distinguishing each push button 9 from other push buttons.

  Moreover, when providing the several push button 9 in the input part 7, it is preferable to have the connection sheet | seat 16 for connecting the several push button 9. FIG. For example, the portable electronic device 1 of the present embodiment includes a resin connection sheet 16 that is bonded between the push button 9 and the pusher 12 and connects the plurality of push buttons 9 and the pusher 12. According to such a connection sheet 16, not only the assembly of the push button 9 and the pusher 12 is facilitated in the assembly process of the mobile electronic device 1, but also the position of the push button 9 and the pusher 12 by the connection sheet 16. And the rattling of the push button 9 and the pusher 12 can be suppressed.

  In the case where a plurality of light shielding members 15 are configured according to the number of push buttons 9, the light shielding members 15 are preferably composed of a sponge 15a having a light shielding property. In this way, as shown in FIG. 4, a plurality of light shielding members 15 are formed with a single sponge 15a, so that the cost of parts can be reduced and the assemblability can be improved. In addition, in the present embodiment, the sponge 15a is disposed between the substrate 5 and the sheet member 13 in a compressed state, and the fixing member 14 is pressed by the repulsive force of the sponge 15a. The accompanying decrease in waterproofness can also be reduced.

  The sponge 15a is preferably bonded to the sheet member 13 but not bonded to the substrate 5. For example, the sponge 15a of this embodiment is bonded to the sheet member 13 via the double-sided tape 15b, and is pressed against the substrate 5 during assembly. If it does in this way, the light shielding member 15 can be provided, maintaining the assembly property of the portable electronic device 1. FIG.
