ABSTRACT:
An improved photographic film processing apparatus is generally of the type wherein an upright processing rack is located within a processing tank adapted to contain a processing liquid for treating the emulsion side of a filmstrip, wherein a timing belt is moved through a vertical guide slot for advancement along the rack to draw successive sections of the filmstrip through a vertical processing channel within the tank, and wherein a plurality of liquid distribution openings to the processing channel direct the processing liquid against the emulsion side of a film section in the processing channel. According to the invention, the tank has respective integral portions shaped to define a first vertical side of the guide slot for the timing belt and to define a first vertical side of the processing channel for the filmstrip. The rack has respective integral portions shaped to define a second vertical side of the guide slot, opposite the first vertical side of the guide slot, and to define a second vertical side of the processing channel, opposite the first vertical side of the processing channel. The integral portion of the rack which defines the second vertical side of the processing channel includes the plurality of liquid distribution openings to the processing channel. This arrangement provides a relatively simple, compact assembly.
