ABSTRACT:
A film cartridge control device is provided for controlling a film cartridge provided with a data disk which rotates in association with a cartridge spool and indicates given information depending upon a position at which the data disk is stopped when a film is completely rewound in the film cartridge. The film cartridge control device includes a drive device that drives and rotates the cartridge spool, a control circuit that performs stop control for causing the drive device to stop the data disk at a predetermined position, and a storage circuit that stores stop control information that indicates that the stop control is being performed. The stop control information is set when the stop control is started and reset when the stop control is finished. The control circuit restarts the stop control after the cartridge spool is rotated by a predetermined amount by the drive device, if the stop control information is set in the storage circuit when the film cartridge control device is started.
