に設けられている。 The cover 7 is provided with holes 11 and 12 into which the operating portion 3a of the slide switch 3 and the jack 4 are inserted, as well as a plurality of holes 13. This hole 13
A pressing part 14 for operating the keyboard switch 2 is arranged inside, and this pressing part 14 is integrally molded with the cover 7 via hinge parts (thin parts) 15 at two places on both ends of one side edge. . The above pressing part 1
A push button 16 is attached to the upper surface of the button 4. Further, on the back surface of the pressing part 14, as shown in FIG.
14c and second regulating ribs 14d and 14e are integrally provided.

復帰力はヒンヂ部15の弾性復帰力による。 As shown in FIG. 3, the operating rib 14a comes into contact with the keyboard switch 2 to operate it when the pressing part 14 is pressed.On the other hand, the lower height of the four regulating ribs Second regulating rib 1
4d and 14e are for preventing overstroke of the pressing portion 14 against forces in the AB direction, as shown in FIG. That is, when a force is applied in the A direction, the rib 14d hits the cover 7, and when a force is applied in the B direction, the rib 14e hits the cover 7 to prevent overstroke. Also, the tallest one
As shown in FIG. 4, the regulating ribs 14b and 14c are designed to have an appropriate gap between them and the printed circuit board 1 during normal operation of the pressing part 14, but when operated with a large force, the printed circuit board It's starting to hit number 1. Note that the return force of the pressing portion 14 after being pressed is based on the elastic return force of the hinge portion 15.

ことにより押釦装置を完成させることができる。 By the way, as mentioned above, the pressing part 14 is covered with the cover 7.
Although forming the hinge part 15 integrally with the hinge part 15 is very advantageous in terms of cost and work, the molded hinge part 15 becomes weak in strength. Conventionally, there are materials that are advantageous in terms of strength as molding materials for hinges, such as polypropylene, but these are highly brittle at low temperatures, the hinge properties change depending on the orientation of the crystals, and they are not very strong in terms of strength. It has drawbacks such as poor dimensional stability during molding. In this embodiment described above, the cover 7 is formed using a normal molding material (ABS resin);
The pressing portion 14 is controlled by the second regulating ribs 14d and 14e.
The structure is such that the load applied to the hinge part 15 during overstroke is reduced, and the first regulating ribs 14b, 14c contact the printed circuit board 1 to protect the hinge part 15 when the pressing part 14 is abnormally operated. In addition, in the case of ABS resin, it is possible to process plating and sputtering, so the push button 1 can be attached to the pressing part 14.
Even without attaching the push button 6, the push button device can be completed by integrally molding the pressing portion 14 and the push button 16 and using the dough as is or by performing secondary processing.

頼性の高い押釦装置を提供することができる。 As explained above, the push button device of the present invention has a small number of parts, so it is easy to assemble and can be manufactured at low cost.In addition, the push button device of the present invention can be easily assembled and manufactured at low cost, and overstroke is achieved by the function of the regulating ribs of two different heights provided on the pressing part. Therefore, damage to the hinge portion due to abnormal loads can be prevented, and an inexpensive and highly reliable push button device can be provided.
