ABSTRACT:
A photographic printer has a film carrier which shifts by 90 degrees in accordance with a frame size of a photographic film. An anisotropic diffusion plate having a light diffusion property only in one direction is attached to the bottom of the film carrier. The anisotropic diffusion plate prevents the quality of photoprints from being degraded by comspicuous scratches on a photographic film which might otherwise be printed on a photographic paper. As the direction of the film carrier is changed in accordance with the frame size, the direction of the anisotropic diffusion plate is changed together with the film carrier.
