PROCESSING LIQUID FILTERING MECHANISM FOR AUTOMATIC DEVELOPING MACHINE

摘要

PURPOSE: To provide the processing liquid filtering mechanism for an automatic developing machine capable of removing sludge of fine particles without decreasing the capacity to stir the developer. ;CONSTITUTION: A first filter 80 of a first circulation system 70 is formed to the size of the meshes to exclusively remove the sludge of somewhat large sizes in the developer, hardly clogs, generates a pressure drop in this section and does not degrade the capacity to stir the developer. A separately provided second filter 106 which is fitted into a drain port 108 of a second circulation system 72 is formed to the size smaller than the size of the meshes of the first filter 80 and a third filter 104 is formed to the size smaller than the mesh size of the second filter 106. The sludge which is not completely removed by the first filter 80 is removed by the second filter 106 and only the sludge finer than the size of the meshes of the second filter 106 is removed by the third filter 104 and, therefore, the clogging rate is low.;COPYRIGHT: (C)1994,JPO&Japio
