Abstract
An improved film pressure plate of a camera for use with a film having a magnetic recording portion is provided. The film pressure plate comprises a magnetic head for recording magnetic information onto the magnetic recording portion of the film and a film contact surface which may include a plurality of small projections formed on a portion of a surface of the film pressure plate. The projections are not provided on at least one of a lengthwise elongated area, which includes the magnetic head, and a widthways elongated area, which may also include the magnetic head. As a consequence of this arrangement, a flatness of the film is assured by pressing the film against the exposure aperture of the camera.
