Provided is a photographic processing device comprising at least one pair of a tray section and an upper section, which are each made by integral molding, arranged so as to form a space. A photosensitive material is passed through the space with its emulsion side turned to the upper plane of the tray section. The upper plane of the tray section and the lower plane of the upper section are equipped with free-rotation rollers for supporting the conveyance of a photographic material. For the adaptation to the width of a photosensitive material to be passed therethrough, two or more of the pairs of the sections are joined together in the width direction with packing. Further, there is provided an automatic developing machine using the foregoing processing device, wherein just before the passage of a photosensitive material through the processing device a processing solution is supplied to the emulsion side of the photosensitive material and spread in a thin layer over the emulsion side during the passage to effect the processing.
L'invention est un dispositif de développement photographique comportant au moins une paire de sections moulées constituée d'un plateau, lequel est l'une des sections, et d'une section supérieure, ces sections étant agencées de façon à former un compartiment. Un matériau photosensible est passé dans ce compartiment, le côté de l'émulsion faisant face au plan supérieur du plateau. Ce plan et le plan inférieur de la section supérieure sont munis de rouleaux porteurs qui servent à faire avancer le matériau photographique. Selon la largeur du matériau photosensible, deux paires de sections ou plus sont jointes au besoin dans le sens de la largeur. L'invention comprend en outre une tireuse automatique utilisant ce dispositif de développement et dans laquelle, juste avant le passage du matériau photosensible dans le dispositif de développement, un mince couche de révélateur est appliquée à l'émulsion du matériau photosensible durant le passage pour effectuer le développement.
