ABSTRACT:
A camera is arranged such that when a film housed in a film cartridge is loaded into a film cartridge chamber of the camera with a leader portion of the film remaining outside the camera and upon closure of the film cartridge chamber, the leader portion of the film is automatically retracted into the camera and the film is wound onto a winding spool. This camera is characterized by providing a detector for detecting occurrence of an abnormal state of movement of the film during operation of retraction of the leader portion of the film into the camera, or during operation of winding the film onto the winding spool, and a warning system responsive to the abnormal-state detector to stop the movement of the film or to produce a warning of the occurrence of the abnormal state.
