ABSTRACT:
A photographic material processing module usable alone for all the processing steps in a processing procedure, or with like modules in side-by-side relation, each module performing one or more of the processing steps. Exposed photographic material is mounted in a cylindrical container having at one end a cover provided with an opening for receiving and discharging processing liquids. The module has a mechanical arrangement for rotating the container a few revolutions in one direction followed by a few revolutions in the opposite direction, and, in preferred form, a mechanism for simultaneously reciprocating the container axially, such movements providing optimum shear relation between processing liquid and photographic material for streak-free processing. A liquid supplying system is provided for feeding measured amounts of processing liquid at proper temperature into the container, and for elevating one end of the container to discharge the processing liquid at the conclusion of a timed processing step. Finally, the module has a transport device for moving the container from the module to an adjacent module at the conclusion of the processing step or steps performed in that module.
