Abstract
A film cartridge in which a supply spool incorporated in a cartridge body is rotated to supply a film wound on the supply spool out of the cartridge body. A film supply unit rotates the supply spool to supply the film out of the film cartridge. A first control unit controls the film supply unit such that a supply operation of the film is started in response to a closing operation of the rear cover of a camera body. A film take-up unit takes up the film supplied by the film supply unit. A second control unit controls the film take-up unit to operate the film take-up unit upon completion of the supply operation of the film performed by the film supply unit. A third control unit interrupts a take-up operation of the film performed by the film take-up unit and reoperates the film supply unit when the take-up operation of the film is impossible during the take-up operation of the film performed by the film take-up unit.
