Abstract
A film feeding device of a camera includes a film feeding mechanism which has an initial winding mode to feed film mounted in the camera and wind a first frame to a shooting position, a first frame winding mode to wind the film by one frame subsequent to shooting, a manual rewinding mode to rewind the film into a film cartridge when a rewinding operation member is operated, and an automatic rewinding mode to rewind the film into the cartridge when the film is rewound through the final edge during rewinding of the film by one frame. A frame number counting mechanism counts a number of shootable frames remaining each time one frame is wound, and counts a number of frames remaining to be rewound each time one frame is rewound. An initial value setting mechanism sets a total number of frames of film as an initial value of the number of shootable frames remaining for the frame number counting mechanism subsequent to initial winding, and sets concurrently the number of frames already shot as the initial value of a number of frames remaining to be rewound for the frame number counting mechanism prior to rewinding. A display displays the frame number counted by the frame number counting mechanism. The initial value setting mechanism computes the number of frames already shot using different methods for the manual rewinding mode and for the automatic rewinding mode.
