ABSTRACT:
A film cartridge permits efficient resetting of a film stored in a film container. A cover is mounted on a cartridge body so as to be movable between an open position and a closed position. In the closed position, a film storage space is defined by the cover and the cartridge body. A film inlet/outlet slit communicates with the outside of the film storage space. A mounted in the film storage space are a spool and a guide plate for guiding a film inserted into the film storage space onto the outer periphery of the spool. The guide plate is pivotally supported. A roller is rotatably mounted on the end of the guide plate opposite the outer periphery of the spool. The guide plate is biased by a spring so that the roller is pressed against the spool. A film inserted through the film inlet/outlet into the film storage space is guided into between the spool and the roller by the guide plate. The spool is rotated in this state to wind the film around the spool.
