Patent ID: 8289682

Claim:
An electronic apparatus, comprising: a first member; a second member provided on said first member for rotation in a first direction which is a circumferential direction around a first imaginary axis which passes said first member and a second direction reverse to the first direction; and a stopper mechanism for defining a range of rotation of said second member around the first imaginary axis; said stopper mechanism including first and second slide members provided on said first member, and a stopper provided on said second member for integral rotation with said second member, said first and second slide members selectively moving between a retracted position and an abutting position; said first and second slid members being moved, when said fist slide member is abutted by said stopper which rotates in the first direction in a first state wherein said first slide member is positioned at the abutting position and said second slid member is positioned at the retracted position, to establish a second state wherein said first slid member is positioned at the retracted position and said second slid member is positioned at the abutting position; said first and second slide members being blocked from movement, when said second slide member is abutted by said stopper which rotates in the first direction in the second state, to stop the rotation of said second member; said second slide member being moved, when said second slide member is abutted by said stopper which rotates in the second direction in the second state, to establish the first state; said first and second slide members being blocked from movement, when said first slide movement is abutted by said stopper which rotates in the second direction in the first state, to stop the rotation of said second members; and an accommodation box in which said first and second slide members are accommodated such that, at the abutting position, said first and second slide members project from said accommodation box, but at the retracted position, said first and second slide members are accommodated in the accommodation box, said stopper mechanism further including a third slide member interposed between said first and second slide members and accommodated in said accommodation box.
