Abstract

L'invention concerne une machine à photocopier comportant un ensemble d'éclairage et de formation d'images à élément de fibres optiques. L'ensemble comprend une rangée linéaire de fibres optiques destinée à remplacer les lentilles classiques d'une machine à photocopier. Cette rangée de fibres fait passer les images de lignes éclairées successivement et portées par un original sur une surface réceptrice en mouvement. La lumière d'une source est dirigée sur un organe de captage qu'elle traverse avant de passer dans les fibres optiques pour éclairer directement une ligne de l'original. Domaine d'application : machines de photocopie, etc
