Abstract
The present invention relates to a method of stopping a film containing a plural number of frames having images recorded thereon. First and second detectors each having at least one photo-electric transducer element are arranged along the feed path of the film. The first and second detectors are disposed in such a manner that when the first detector receives the light from the frame, the second detector receives the light from the blank portion (non-image portion) between frames. A signal is produced only when the first detector detects a desired frame and the second detector detects the blank portion at the same time during the feeding of the film. After the generation of the signal, the film is further advanced in a determined direction by a determined length of the film and then the film feeding is stopped to stop the desired frame in the film at a determined position.
