Abstract: A camera includes a camera body, the camera body including a cartridge compartment, the cartridge compartment having a cover, the cover being movable between an open and a closed position. The camera includes a lock mechanism, the lock mechanism having a locking state in which the cover is prevented from being moved to the open position from the closed position, even if an operation to open the cover is executed, and an unlocking state in which the cover is movable from the closed position to the open position. The camera further includes a drive mechanism which drives a photographing lens, and an actuating mechanism, the actuating mechanism being movable between a first and a second position of the actuating mechanism by the drive mechanism. The actuating member switches the lock mechanism to the locking state when the drive mechanism moves the actuating mechanism to the first position of the actuating mechanism.
