Abstract
Disclosed is a photographic film-feeding apparatus for positioning picture frames of a film to an exposure position in a camera, wherein there is provided a feeding mechanism which is controlled so as to wind or rewind the film by two frames in response to every picture-taking operation. When starting the rewinding process, the feeding mechanism is further controlled so that the film is rewound so as to position a picture frame being adjacent to the latest exposed frame in the winding process to the exposure position and thereafter the film is rewound by two frames.
Claims3
A photographic film-feeding apparatus for positioning picture frames of a film to an exposure position of a camera comprising,
- a film-feeding means for winding and rewinding a film in said camera by using an electric motor;
- a frame signal-generating means for generating a frame signal representing a picture frame passing through the exposure position while the film is wound or rewound by said film-feeding means;
- a wind control means for controlling said film-feeding means to wind the film by two frames based on the frame signal from said frame signal-generating means in response to every picture-taking operation;
- a return control means for letting said film-feeding means to start rewinding the film when judging the latest exposed frame to be the last picture frame in the winding process;
- and
- a rewind control means for controlling said film-feeding means to rewind the film so that, when starting the rewinding process, the film is rewound so as to position a picture frame being adjacent to the latest exposed frame in the winding process to the exposure position on the basis of the frame signal from said frame signal-generating means, and thereafter the film is rewound by two frames in response to every picture-taking operation.
