Abstract
A plate slidable on a film back has a hook which abuts a pin on a camera body as the film back is inserted. The hook is forced to slide as the film back is inserted and pulls a locking pawl on the film spool gear out of engagement until inserting is completed at which time the hook snaps back and locks the film back into the camera.
