ABSTRACT:
An image forming apparatus includes a button member having an operation button portion, a part of which is translucent, an LED arranged behind the operation button portion, a switch arranged behind the button member and a button supporting member, which supports the button member rotatably. The button member is rotatably supported by a shaft portion provided at the button supporting member and the operation button portion is pressed by a plate spring portion out of the image forming apparatus. When the operation button portion is pressed against the pressing force of the plate spring portion, a button contact portion provided at a front end of the plate spring portion allows the switch to operate. In this configuration, the shaft portion, the plate spring portion, the button contact portion, the switch and the LED are arranged so as to overlap the button member for simplification.
