Patent

CA 2113602

A photographic printing apparatus having a single light source and a reflecting mirror. The mirror is provided between the light source and the light-modulating device having light-modulating filters, a mirror tunnel and diffusers and has a light-passing portion. Most part of the light from the light source is reflected by the mirror and used for exposing negative films after passing it through the light-modulating device. The remainder of the light from the light source passes through the light-passing portion and is used for scanning.

L'invention est un appareil d'impression photographique comportant une seule source lumineuse et un miroir. Ce dernier est monté entre la source lumineuse et un modulateur de lumière doté de filtres de modulation, d'un tunnel à miroir et d'un diffuseur, et comporte une partie de transmission de lumière. La plus grande partie de la lumière émise par la source est réfléchie par le miroir et est utilisée pour l'exposition des négatifs après avoir traversé le modulateur de lumière. Le reste de la lumière émise par la source traverse la partie de transmission de lumière et est utilisée par le balayage.
