Abstract
A scanner as a film analyzer, which inspects a frame on photo film, is consecutively supplied with the film by a notcher, which forms a notch in the film. The scanner includes an image area sensor which subjects the frame on the film to photometry. A pair of feeding rollers feed the film, so the film passes the photometric station. A winding shaft winds the film fed from the photometric station. A dancer roller displaces one portion of the film from a feeding path to form a loop. A set of loop checking sensors is disposed with the dancer roller, and checks displacement of the film in comparison with a predetermined upper limit. The notcher is disabled if the film displacement is greater than the upper limit. The displacement of the film is checked in comparison with a predetermined lower limit. The image area sensor is disabled if the film displacement is smaller than the lower limit.
