The adhesion of the film 11 to the magnetic recording portion 11a is improved, and data such as shooting information is recorded more accurately. Further, a uniform pressing force acts on the photographing screen portion 11c, which also has the effect of flattening the photographing screen portion 11c. Furthermore, since it is not necessary to dispose the pressure bonding pad, the roller, the biasing spring and the like, the film feeding load is small and the camera can be miniaturized.

いる。As a modified example of the second embodiment, it is possible to propose a camera to which the photographing screen portion of the film is offset with respect to the width of the film. FIG. 6 is a view showing the arrangement of the magnetic head 22 on the film 21 of the camera of the above modification. As shown in FIG. 6, the film 21 is provided with a photographing screen portion 21c, a magnetic recording portion 21a, and a perforation 21b as in the case of the second embodiment. Then, the magnetic head 22 is provided on the magnetic recording portion 21a of the film 21.
It has a shape capable of being continuously pressed along the width direction which is substantially orthogonal to the film running direction D3. The position of the end face of the magnetic head 22 on the film 21 is determined by the film traveling direction D3 of the photographing screen portion 21c.
Equidistant to the centerline C3 in the width direction (distance Y7
= Y8). In FIG. 6 , the distance Y5 from the center line C3 to the upper and lower edges of the photographing screen portion 21c,
The distance Y6 is equal, but is offset with respect to the full width of the film.
