Abstract
Abstract A mechanism, for reproducing images of a developed film, which reads film information recorded in a magnetic track formed along a pair of edges extending longitudinally of a leader of the film. The reading of the magnetic track is carried out by pressing a magnetic head against the magnetic track of the film leader at the time of rewinding into a cartridge case the film which is once fed out a predetermined length from the cartridge case. When the film is rewound into the cartridge case at the time of reading the film information, the surface of the film leader is pressed by the magnetic head uniformly because the film leader is tightened even and flat by a tension working between the cartridge case and the magnetic head.
