ABSTRACT:
An apparatus using a film cartridge in a system that a leading portion of a film contained in a cartridge is thrust to be conveyed from the cartridge, wherein an indicator showing an exposure condition is reset to an original state when an initial loading, which is executed on a film cartridge loading in an apparatus, is not executed normally, and the film is rewound, thus, it indicates "unexposed" when a new film cartridge is loaded. While, when a winding up operation is not executed normally during a photographing, a film is rewound and an indicator showing an exposure condition, is set so as to indicate that the film is exposed. Thus, it prevents from causing a double exposure.
