【Example】

 An embodiment of the present invention will be described in detail with reference to the drawings shown in FIGS.

FIG. 1 is an overall view of an electronic device, and FIG. 2 is an exploded perspective view of a push button device provided in an escutcheon. In these figures, 1 is an electronic device main body, 2 is an escutcheon attached to the front surface of the main body 1, 3 is a push button attached to the escutcheon, 5 is a switch attached to a printed circuit board 6, and 10 is a main button device. Show.

The electronic device main body 1 has a flat box shape, and an escutcheon 2 is detachably attached to an opening on the front surface. The front surface of the escutcheon 2 has square holes 2a for mounting a push button 3 including one main button 3a and a plurality of, for example, two sub-buttons 3b. The main button 3a and the sub-button 3b are inserted from the inside of 2.

The main button device 10 includes an elastic member 4 that is also a push button connection body, and the main button 3 a of the plurality of push buttons 3 is integrally formed on the elastic member 4.

The elastic member 4 is formed of a resin having elasticity, and a slave button pressing portion 4a is formed behind each slave button 3b so as to be positioned. Further, these sub-button pressing portions 4a are connected to the connecting portion 4b provided in the vertical direction via the elastic portion 4c, and the upper end of the connecting portion 4b is elastic by the connecting portion 4d provided in the lateral direction. It is connected to the main button 3a via the portion 4e.

On the front and rear surfaces of each of the connecting portions 4b and 4d in the vertical and horizontal directions, a protrusion-shaped fulcrum having a length substantially the same as the clearance between the escutcheon 2 and the printed circuit board 6 housed in the escutcheon 2. The portions 4f and 4g are provided so as to project.

On the other hand, the printed circuit board 6 is a member provided with a switch, and the switch 5 is soldered to the printed circuit board 6 so as to be positioned behind the main button 3a and the sub button 3b. The switches 5 can be operated by pressing the push button 3 attached to the escutcheon 2.

To explain the operation, when assembling the push button device into the escutcheon 2, first, the plurality of secondary buttons 3b are inserted into the square holes 2a of the escutcheon 2, and then the elastic member 4 is integrated. The main button 3a is inserted into the square hole 2a of the escutcheon 2.

Next, in this state, the printed circuit board 6 to which the switch 5 is attached is assembled into the escutcheon 2, and the tips of the fulcrum portions 4f and 4g projecting from the front surface of the elastic member 4 are set on the inner surface of the escutcheon 2. Then, the print substrate 6 is brought into contact with the tips of the fulcrum portions 4f and 4g provided on the rear surface.

Since the elastic member 4 is fixed by this, the main button 3a integrated with the elastic member 4 is attached to the escutcheon 2 without rattling, and the sub button pressing portion 4a of the elastic member 4 is attached to the sub button. Since 3b is pressed against the inner surface of the escutcheon 2, the secondary button 3b can be attached to the escutcheon 2 without play.

After the assembly, when the main button 3a is pushed, the elastic portion 4e elastically deforms with the fulcrum portion 4g as a fulcrum, so that the switch 5 behind the main button 3a can be operated by the main button 3a and the sub button 3b can be operated. When pushed, the elastic portion 4c elastically deforms around the fulcrums 4f and 4g as fulcrums, so that the switch 5 behind the sub button 3b can be operated by the sub button 3b.

FIG. 3 is an exploded perspective view of a push button device showing another embodiment in which a light guide plate 7 for illuminating the push button 3 is provided, and FIG. 4 shows that the sub button 3 b is attached from the front side of the escutcheon 2. In the exploded perspective view of the push button device, the push button device in which the slave button 3b is attached from the front side of the escutcheon 2 is configured so that light leaks from the gap between the square hole 2a of the escutcheon 2 and the slave button 3b. In order to prevent this, a light shielding portion 4h is provided on the secondary button pressing portion 4a of the elastic member 4.

Further, in each of the embodiments, the light guide plate 7 has the openings 7a in the switch 5 portion, in which the respective switches 5 can be accommodated, and the light guide section side of these openings 7a is as shown in FIG. The inclined surface 7b has an angle of about 45 °, and the incident light from the light source 8 is reflected by the inclined surface 7b toward the push button 3 side so that the push button 3 is illuminated from the inside. In the case of FIG. 3, if the flange portion of the secondary button 3b is made opaque by painting or the like, the light shielding portion 4h is unnecessary.

When it is not necessary to illuminate the secondary button 3b, that is, when it is not necessary to mold the secondary button 3b with a material such as brittle acrylic, the secondary button 3b may be integrally formed with the primary button 3a. . Furthermore, it is desirable that the number of fulcrums is (total number of primary buttons and secondary buttons-1).

[0024]

[Effect of device]

 As described in detail above, in the present invention, since the primary button and the secondary button are elastically pressed by the elastic member by the escalation, there is no backlash. As a result, the feel during operation is further improved, and since a proper gap can be provided between each push button and the switch, smooth switch operation can be obtained.
