ABSTRACT:
A film pressure plate is provided with a magnetic head which records magnetic information in a magnetic recording section at lower edge of photographic film. A saddle-shaped pad is arranged at the front of a rail plate in such a manner as to face the magnetic head. There is provided a leaf spring for pushing the pad from an opening formed in the rail plate in a direction for the pad to advance onto a film feed path such that a longitudinal direction of the leaf spring corresponds to the film feed direction. A fixed end of the leaf spring is fixed at the upstream of a direction in which the film is fed when the magnetic data are recorded. Thereby, the pad can stably contact with the face of the film while the film is being fed, and the magnetic recording section on the film can come into contact with the magnetic head in a stable manner.
