ABSTRACT:
A photographic processing apparatus for processing film includes processing units, such as developing, fixing and rinsing units, each of which is constructed to cause the film to be conveyed in a straight horizontal path between conveyance rollers, none of which are immersed in processing liquid. Each processing unit includes at least one processing chamber defining member extending longitudinally across the path of said film and carrying processing liquid in a chamber defined therein. The chamber is open to the moving film via an inlet slot and an exit slot. Pairs of conveyance rollers are positioned just upstream and just downstream of said inlet and outlet slots, respectively. Liquid conveyance means pumps a processing liquid through said chamber and picks up the processing liquid exiting the chamber via the slots and being squeezed off the film by the rollers.
