ABSTRACT:
A photographic film processing apparatus comprises a water tank for containing a constant quantity of fresh water, and one or a plurality of processing units each comprising a pair of feed rollers disposed with their circumferences in close contact with each other, a pair of delivery rollers spaced apart from the pair of feed rollers and disposed with their circumferences in close contact with each other, a pair of sealing rollers disposed with the circumference of one of them in close contact with the circumferences of the top feed roller and the top delivery roller and with the circumference of the other in close contact with the circumferences of the bottom feed roller and the bottom delivery roller, and a pair of support plates disposed respectively on the opposite sides of the rollers so as to support the rollers for rotation and to define a liquid-tight processing chamber by the circumferences of the rollers and the inner surfaces thereof. The processing unit or units are immersed completely in fresh water contained in the water tank, and a processing liquid is circulated through each processing chamber, at a high velocity across the direction of travel of a film in the processing chamber.
