ABSTRACT:
A photographic camera is provided with a light emission diode which emits light toward a photographic film loaded in the photographic camera in response to shutter release, and a mark recording mechanism which records marks on the film by light emitted from the light emission diode in a number which is changed in response to movement of an external control member which is operated to designate an aspect ratio of a print. The mark recording mechanism includes a light-shielding plate member which is provided with a plurality of windows and is fixed in the camera body with the windows opposed to the photographic film and a rotary light-shielding plate which is disposed between the light-shielding plate member and the light emission diode and is rotated to selectively close and open the windows in response to movement of the external control member.
