ABSTRACT:
A camera capable of magnetic recording includes a pressing pad for a magnetic head. The pressing pad is secured to the camera body and the head is made movable in order to increase the proximity of the head to the film and to enable reliable application to a low-cost, compact focal plane shutter camera. Above and below the aperture in the camera body, there are provided a pair of film rails and a pair of pressure plate rails formed so as to be higher than the film rails. An extended portion is formed on the film rail, and in the center of the extended portion, a recessed portion is made. A graded portion is formed to the left side of the extended portion, and a circular arc portion is formed to its left side. Below the pressure plate, there are provided a hole through which the magnetic head is secured to an actuating member with a mounting portion pressing the film, and a pair of stoppers for limiting the displacement of the magnetic head in the optical axis direction.
