Abstract
Abstract Described herein is a compact photographic processor which uses small volumes of processing solution to achieve effective processing without the need for process control. The processor comprises an applicator element (50) having a plurality of orifices formed along its length, a plurality of reservoirs (54, 56, 58) each containing processing solution, and a pressure system (60, 61, 62). The element (50) is connected to one side of the reservoirs (54, 56, 58) by means of a manifold (52), the other side of the reservoirs (54, 56, 58) being connected to the pressure system (60, 61, 62). The processing solutions may be dispensed from the element (50) as jets.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
121 words
Photographic processing apparatus for processing photographic material comprising: support means for supporting the material to be processed; at least one reservoir containing processing solution; applicator means connected to each reservoir and operable for applying processing solution to the material; and control means for controlling the applicator means to provide an appropriate amount of processing solution to effect processing of the material; characterized in that the applicator means comprises at least one applicator element having at least one orifice formed therein through which processing solution is directed for application to the material, and valve means for controlling the flow of processing solution through the orifices in each applicator element, wherein at least one reservoir contains developer solution made from a developer precursor.
