Patent ID: 8228424

Claim:
An electronic device comprising a casing with an opening, and a cover member for covering said opening, said cover member including: a cover part for covering said opening; a shank projecting from a rear surface of said cover part, while passing through a hole defined in said casing; and a protrusion sticking out of said shank, at a position opposite to said cover part with respect to said hole, in a direction crossing an axis of said shank, said cover member being capable of moving back and forth along said axis of said shank, between a depressed position where said cover part covers said opening and a pulled-out position where said cover part is apart from said opening, said casing having a first receiving part for receiving said protrusion to prevent the pivotal movement of said cover member about said shank when said cover member moves back and forth between said depressed position and said pulled-out position, and receiving said protrusion to prevent the pressing-in of said cover member after having moved pivotally about said shank while enabling the pivotal movement of said cover member about said shank when said cover member is in said pulled-out position.
