Claims

[Scope of Claim for Utility Model Registration] A fixed key part is provided on the back cover side, and a slidable movable key part is provided on the camera body side, and the movable key part is directed by a spring to the engagement position with the fixed key part. When the back cover is closed, the fixed key part pushes the movable key part and once it is retracted to the non-engaged position, the two key parts are engaged by the above biasing force. In a camera in which the back cover is held in a closed position with respect to the camera body, a protrusion is provided integrally with the movable key portion on the camera body side, and the movable key is attached to the camera body side from a first position protruding toward the back cover side. The second part facing the protruding part of the part
The third switch that opens and closes the camera back opening/closing detection switch via the position
A camera back opening/closing detection member is provided which moves from the first position to the second position by the closing operation of the camera back.
position, and then by moving the movable key part to the engagement position, the protruding part moves the detecting member from the second position to the third position. .
