ABSTRACT:
A device for restricting a movement of a sliding cover of a camera includes a photographing lens which is movable between a photographing position and a retracted position. A sliding cover is movable between fully-closed and photographing positions, at which the sliding cover covers the photographing lens when the photographing lens is at the retracted position and does not cover the photographing lens when the photographing lens is at the photographing position, respectively. A locking lever can move to a position at which it can engage a locking section of the sliding cover, when the sliding cover is at the fully-opened position. A lock releasing member is actuated when the photographing lens moves to the retracted position. An intermediate member is actuated by an actuating force of the lock releasing member. A clutch mechanism, provided between the locking lever and the intermediate member, rotatively moves the locking lever and the intermediate member together to a lock releasing position when a force applied to the locking lever is less than a predetermined value. The clutch mechanism allows the intermediate member to run idle relative to the locking lever when the force exceeds the predetermined value.
