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.
