Abstract

Apparatus for developing a photographic emulsion carrier. The carrier travels through a succession of tanks of photographic processing fluid. The apparatus includes mechanisms that forward the carrier through the tanks, a drive device that operates the forwarding mechanisms, guides that guide the carrier from one tank into the next, and means that connect an inlet for each processing fluid with its associated tank. The apparatus also includes at least one separate assembly associated with at least one tank, for forming a cascade which includes means for conveying the processing fluid from at least one cascade stage to the tank. The assembly, for forming the cascade is a separate module that rests as a cover on the tanks and has a separate inlet for receiving processing fluid. The cascade assembly accommodates a mechanism that forwards the carrier through it. This mechanism couples with the mechanisms that forward the carrier through the tanks while the cascade assembly is resting on them.
