摘要：
With respect to a push button, a part of a depressing portion is detected by a photo sensor when the depressing portion urged upward by a spring is depressed and stroke of the depressed depressing portion reaches a predetermined distance. Thereby, switch between OFF and ON is carried out. Also, the push button includes a metal dome. Load of the spring works on the depressing portion when depressed. Further, when the stroke of the depressed depressing portion reaches a predetermined distance so as to switch between OFF and ON, the load of the spring and that of the metal dome integrally work on the depressing portion.
