Patent ID: 6966709

Claim:
A camera comprising: a photographic lens barrel movable along a lens movement path between a photographable position and a non-photographable position; a barrier movable along a barrier movement path between a closed position where the barrier covers the photographic lens barrel and an open position where the barrier is withdrawn from a front surface of the photographic lens barrel, the barrier movement path intersecting the lens movement path; a locking member being supported so as to be movable along an optical axis of the photographic lens barrel between an engaging position where it is possible to engage the barrier when the barrier moves to the closed position and a withdrawn position where it is displaced from the barrier; a pressing member for pressing the locking member towards the withdrawn position and; a locking member movement restricting means for restricting movement of the locking member responsive to movement of the photographic lens barrel, enabling the locking member to move against the pressing force of the pressing member to the engaging position to engage the barrier when the photographic lens barrel is at the photographable position, and enabling the locking member to be withdrawn by the pressing force of the pressing member to the withdrawn position and disengaged from the barrier when the photographic lens barrel is at the non-photographable position; wherein the locking member engages the barrier, and prevents movement of the barrier from an attempt to move the barrier from the open position to the closed position when the photographic lens barrel is located in the barrier movement path of the barrier, and furthermore, engagement of the locking member with the barrier is maintained so that an operation force applied to the barrier in the closing direction does not affect the movement of the photographic lens barrel if the operation force is continuously applied even in a state in which the photographic lens barrel is displaced from the barrier movement path of the barrier.
