To prevent double exposure from occurring by inhibiting the reuse of a film cartridge when an abnormality is detected at the rewinding of a film.

This camera is provided with a control means 1 driving a magnetic head by using a magnetic recording circuit 2, reading out the information of the magnetic storage part of the film with a magnetic storage part and discriminating the existence of a frame on which the information is not written when the halfway rewinding of the film is executed by a halfway rewinding means (a halfway rewinding switch 14, a control circuit 1 and a film feeding driving circuit 3) and controlling the display means of the film cartridge so as to display 'all the frames are already exposed' when it is discriminated that there is the frame on which the information is not written. Then, the film cartridge is inhibitted from being loaded again and used.
