Abstract

L'invention concerne un dispositif d'impression photographique permettant de produire une image visible à partir d une information reçue sous forme de signaux électriques distincts. Les signaux sont appliqués, via une source lumineuse de données 40 et un dispositif de commande 38 à plusieurs dispositifs 32, 34 qui font fonction chacun de source lumineuse en réponse à la réception d'un signal électrique et qui sont disposés suivant un réseau au voisinage d'une surface photosensible 4. Selon une forme préférée, le dispositif d'impression est du type électrophotographique et la surface photosensible est une surface photoconductrice 4 qui reçoit une charge en un poste de chargement 16 de sorte que la lumière venant des sources lumineuses produit une image latente électrostatique qui peut être développée dans un poste de développement 42, puis transférée sur papier ordinaire. L'invention permet d'appliquer à l'impression d'une information codée sous forme électrique les avantages, notamment de rapidité, des processus mis en oeuvre dans les appareils de photocopie.The invention relates to a photographic printing device for producing a visible image from information received in the form of separate electrical signals. The signals are applied, via a data light source 40 and a controller 38 to several devices 32, 34 which each function as a light source in response to the reception of an electrical signal and which are arranged in a network in the vicinity of a photosensitive surface 4. According to a preferred form, the printing device is of the electrophotographic type and the photosensitive surface is a photoconductive surface 4 which receives a charge at a charging station 16 so that the light from the light sources produces an electrostatic latent image which can be developed in a development station 42 and then transferred to plain paper. The invention makes it possible to apply to the printing of information encoded in electrical form the advantages, in particular of speed, of the processes implemented in photocopying apparatus.
