ABSTRACT:
A roll of film placed in a camera is restrained from completely free movement by a lever which frictionally engages the support shaft holding the film roll. When the leader is wound on the take up roll, the friction on the support shaft prevents bunching or misalignment of the film by keeping it taut. When the camera back is closed the lever is moved so as to be out of frictional engagement with the support shaft.
