ABSTRACT:
A camera which includes a film cartridge whose spool is adapted to be set in different rotational positions with respect to a film cartridge main body between unused state and used state of the film cartridge, and a camera body having a film cartridge accommodating portion, and is arranged to show that the film cartridge is in the used state when the used film cartridge is inserted in the accommodating portion of the camera body.
The film cartridge is provided with shaped portions having different shapes from each other corresponding to the two rotational positions, while the film cartridge accommodating portion of the camera body is provided with an ejecting member, a detecting member for detecting the state of use of the film cartridge through its movement controlled by the differently shaped portions of the film cartridge upon insertion of the film cartridge into the film cartridge accommodating portion, and a display member for detection to be shown at a predetermined position in responsive movement to the detecting member, upon detection that the film cartridge is in the used state by the detecting member.
