To shorten time required for rewinding a film by shortening time required for detecting the finish of the rewinding of the film.

A perforation signal obtained by detecting perforations moved according as the film is fed by a photoreflector 33 and provided with at least a first and a second states corresponding to the existence of the perforation is outputted from the film 28 of a film cartridge 26 loaded in a camera. When the perforation signal of the first state from the photoreflector 33 is continuously outputted in first prescribed time or more or the perforation signal of the second state is continuously outputted in second prescribed time or more, the rewinding of the film 28 by a film feeding mechanism 38 is stopped by an instruction from a microcomputer 11.
