Abstract
An apparatus adapted to a film cartridge in which a film is contained, comprises an operation device which is operable for arbitrarily rewinding the film into the film cartridge before the film is wholly used, an indication device for causing the film cartridge to provide an indication that the film is partly used upon a film rewinding operation of the operation device and a determination device for determining whether a predetermined transporting action of the film is performed. The indication device causes the film cartridge to provide the indication that the film is wholly used, if the determination device determines that the predetermined transporting action of the film is not performed and the film has been rewound.
