Abstract
A sound cine camera with a cassette-receiving compartment, in which a pinch roller is movable toward a continuously rotating capstan to drive a motion-picture film, is provided with a manually operable control member whose displacement into an off-normal position, against the force of a restoring spring, prepared or completes an energizing circuit for the film drive. The control member is linked with a pinch-roller support through a releasable coupling which remains effective only as long as the compartment cover or a latch thereof is in a closure position. Clamping pressure is exerted upon the pinch roller by a biasing spring engaging its support and acting upon the control member through a camming or toggle mechanism which reduces the holding force required to maintain that pressure when the control member is in its off-normal position.
