Abstract
The time after film is rewound up to a first frame until a film cartridge holding the film is allowed to be taken out is divided with the time required for rewinding the film by the currently-exposed frames. A delayed frame number is displayed at the time which is delayed from a time when the actual frame corresponding to the delayed frame number has been rewound for a delay time which is found based upon a number of the currently-exposed frames. Thus, a time in which a displayed number '1' changes to such a mark as 'E' can be decreased, thereby preventing the user from opening a film cartridge chamber before the film is completely rewound.
