Abstract

PURPOSE: To prevent the idle shooting of a film owing to the failure in its winding by warning the failure in sure winding of the film through release locking of the shutter.
CONSTITUTION: A film 8 is wound on a spool 7 and the broad part 8b of the film 8 is detected by means of the projection 4a provided to a film guide 4 and the inserting part 7a provided to the spool 7. This detecting mechanism is abled only when the lever 5 detects the existence of patrone loading. The detecting mechanism detects the failure in sure winding of the film 8 on the spool 7 from the insertion motion of the projection 4a into the inserting part 7a, then, it locks the releasing of the shutter by its detection output. It detects the sure winding of the film 8 on the spool 7 from the disengagement motion of the projection 4a from the inserting part 7a, then, it releases the locking of the releasing of the shutter.
