Abstract:
A camera, comprising:a photographic lens barrel having a lens moving path along which said photographic lens barrel is movable between a photographing-possible position and a photographing-impossible position; a barrier having a barrier moving path along which said barrier is movable between a closed position at which said photographic lens barrel is covered by said barrier and a retreated position at which said barrier is retreated from the front face of said photographic lens barrel, and which said barrier moving path crosses the lens moving path of said photographic lens barrel; a lock member that is movable to a lock release position so that said barrier is allowed to move to the closed position by using the movement of said photographic lens barrel to the photographing-impossible position, and movable to a lock position to prevent the movement of said barrier in the closing direction when said barrier is located at the retreated position; a lock engaging portion, by engaging with the lock member, that starts movement of said lock member from the lock release position toward the lock position by using a manual closing operation of said barrier; a photographic lens barrel driving portion for driving said photographic lens barrel between the photographing-possible position and the photographing-impossible position; a lock release engaging portion for moving said lock member from the lock position in a lock releasing direction using the movement of said photographic lens barrel to the photographing-impossible position by said photographic lens barrel driving portion; and an urging member, wherein said lock member is a rod-shaped member that is rotatable and movable in the axial direction, and said lock member is driven from the lock release position to the lock position by said urging member, said lock member is rotated against the urging force of said urging member through the engagement with said lock engaging portion, and moves in the axial direction from the lock release position to the lock position.
