Abstract:
The film feed control apparatus performs frame feed operation in which a photographic film is fed in a specific direction when a given photographic frame of the photographic film is being set at a specific position, and the photographic film is stopped when a next photographic frame is set at the specific position. The film feed control apparatus is provided with a feed device that feeds the film, and a control device that controls the feed device in such a manner that, when an unfinished film, which includes exposed frames and unexposed frames, is loaded, stops the film if an unexposed frame is set at the specific position while the unfinished film is being fed in the specific direction, which is the same as the direction of film feed during the frame feed operation.
