Abstract
A pinch roller actuating device for a sound motion picture camera including portion connected to a rotatable pinch roller to maintain the roller out of and in engagement with a capstan responsive to a movable camera actuating member having a limiting stop which defines the maximum displacement of the actuating member. A spring member is provided to move the pinch roller into engagement with the capstan after the actuating member is displaced beyond its mid-point. A bracket is arranged to prevent movement by the spring when the stopper engages the connecting portion, and instantly engages the pinch roller with the capstan by being suddenly moved by the spring member when the connection between the stopper and the connecting portion is released.
