の操作が行われる構造が用いられるようになった。The mounting substrate has been reduced in size due to the high-density integration of semiconductor devices, and active elements such as switches have become smaller and can be mounted on the mounting substrate. On the other hand, when the switch is operated by a human, the size of the human finger does not change, and it is difficult to reduce the size of the operation button. Conventionally, switches with built-in operation buttons were attached to the housing and connected to the mounting board by wiring.However, to simplify the process, the operation buttons and switches were separated and the operation buttons were mounted on the housing. Attach the switch with a small pressing part to the mounting board, arrange the pressing part close to the operation button of the housing, and physically transmit the pressing of the operation button to the pressing part of the switch, Structures in which operations are performed have come to be used.

In the third embodiment, the left and right ribs 222 are divided into two pieces, respectively. The other configurations and operations are the same as those of the first embodiment, and the description is omitted. 9 and 10, the second protrusion 233 corresponds to one rib 222 on each of the left and right sides, so that the resistance to the pressing of the operation button 203 is small. Here, when the width of the second convex portion 233 is increased so that the second convex portion 233 corresponds to the two ribs 222 on the left and right sides, the second convex portion 233 pushes the two ribs 222 and the operation is performed. The resistance to the pressing of the button 203 increases.

とができるという効果がある。When it is desired to increase the pressing force of the operation button, the thickness of the rib in contact with the convex portion of the operation button is increased,
Conversely, if you want to reduce the pressing force of the operation button, you can reduce the thickness of the rib so that the pressing force of the operation button matches the target user or the operation button function. If necessary, change the elasticity of each, and select and combine appropriate operation buttons from a plurality of operation buttons with protrusions with different numbers of contact with the ribs to match the target user or operation button function There is an effect that the pressing force can be reduced.
