Abstract: An improved diazo film processing and developing system has warm-up and steady state heaters along with gravity loading of the film drive rollers and cast aluminum pre-heat and developing chambers. The chambers use resilient or leaf spring seals and a stainless steel aqueous ammonia separation chamber is contiguous and directly connected with the developing chamber for maintaining a temperature differential between the two chambers.

Abstract: A processor for developing diazo film has flat platens disposed within a housing and spaced apart a distance to accommodate the thickness of the film. The housing includes an inlet and an outlet aligned with the space between the platens and means for advancing a film from the inlet and through the space between the platens in a preheat chamber and in a developing chamber and for discharging the developed film. The platen facing the emulsion side of the film is heated in the preheat chamber so that the film is heated to a desired temperature prior to developing. A metered amount of aqueous ammonia is supplied through a lower chamber at the inlet end of the developing chamber wherein the ammonia is separated from the water by reason of the differential temperature and ammonia vapor rises to contact the emulsion side of the film for rapidly developing thereof and the water is drained from the lower chamber.

Abstract: A microfiche recorder has an X carriage movable along a guide in the X direction and a Y carriage mounted on the X carriage and movable in the Y direction. The guide provides a pivot connection wherein the X carriage and the Y carriage are swingable in a Z direction toward an away from a microfiche holding platen.
