ABSTRACT:
An apparatus for processing a web or sheet of photosensitive material by passing it through a processing tank is provided. The apparatus includes a processing tank of the closed type having an inlet slit and an outlet slit for the photosensitive sheet. The tank is filled with processing solution and replenished with solution from an external supply. Each of the inlet and outlet slits has such a small opening that the processing solution may not leak through the slit due to its surface tension. The photosensitive sheet is carried into the tank via the inlet, through the tank along a predetermined path, and then out of the tank via the outlet by means of rollers or other conveyors.
