Abstract
Abstract An apparatus for processing dry silver recording material includes a heated first curved platen over which a continuous belt is driven to heat the belt before engaging the recording material, and a second heated curved platen over which the recording material and continuous belt pass. The second curved platen is heated by a plurality of heaters to maintain constant belt and platen temperature while the recording material is passing therebetween, ensuring uniform and fast development of the recording material.

An apparatus for processing dry silver recording material, comprising: insulated housing means having an input opening through which the recording material is introduced into said insulated housing means and an output opening out of which the recording material is extracted from said insulated housing means; first platen means disposed in said insulated housing means extending from said input opening to said output opening along which the recording material moves; heating means provided on said first platen means for heating said first platen means therealong for developing information on the recording material; continuous belt means disposed in said insulated housing means; roller means disposed in said housing means including input roller means adjacent said input opening, output roller means adjacent said output opening, and intermediate roller means between said input roller means and said output roller means, said continuous belt means movably mounted onto said input roller means, output roller means, and said intermediate roller means, said continuous belt means adapted to be moved via said roller means so that said continuous belt means engages said first platen means thereby frictionally moving the recording material along said first platen means; second platen means disposed in engagement with said continuous belt means between said input roller means and said intermediate roller means; and heater means provided on said second platen means for heating said second platen means which heats said continuous belt means above the temperature of said first platen means whereby said continuous belt means raises the temperature of the emulsion side of the recording material to development temperature at a fast rate.
