PURPOSE: To achieve the flatness of film and to prevent the occurrence of frictional force by constituting a camera in such a way that a means regulating the position in the optical axis direction of a film abuts on the film face at the time of photographing and retreats to a position away from the film face at the time of feeding the film.

CONSTITUTION: After the film 13 is fed, an aperture frame 64 is brought into press-contact with a stopper 71 with the energizing force of a spring 70. Consequently, the film 13 is brought into press-contact by an aperture face 64a to show flatness. Simultaneously, since the film 13 is position-regulated by the stopper 71, the position on which a photographing lens focuses can be found precisely. The aperture frame 64 regulating the position in the optical axis direction of the film 13 is retreated from the film face during feeding the film, whereby the occurrence of frictional force can be prevented.
