ABSTRACT:
A camera according to the present invention which uses a film cartridge equipped with an indicating section for indicating an exposed state of a film housed within the film cartridge. The camera comprises a film compartment for accommodating the film cartridge, a cover member for closing the film compartment, and an ejector formed within the film compartment. The ejector blocks the mounting of the film cartridge when the exposure-state indicating section takes a development-completed condition indicating position, a completely exposed condition indicating position or a partially exposed condition indicating position, while allowing the film cartridge to be mounted therein when it takes a non-exposed condition indicating position. In addition, the ejector pushes the film cartridge out of the film compartment when the cover member is opened after a completion of photography.
