ABSTRACT:
Electronic apparatus that can be disposed in a small space and allows multidirectional input without impairment of a click feeling. A cross key including a plurality of pins is elastically held by an operating member holding mat including a plurality of holes into which the respective pins are insertable. An analog switch overlapped on the operating member holding mat outputs a signal when one of the pins comes into direct contact with the analog switch in response to operation of the cross key. A metallic dome sheet overlapped on the analog switch outputs a signal when one of the pins comes into contact with the metallic dome sheet via the analog switch in response to operation of the cross key. The metallic dome sheet outputs a signal after the analog switch outputs a signal.
