Photographic processing apparatus

摘要

Apparatus for processing a photographic sheet material in at least one processing stage which includes a feed roller array for transporting the material to or from the stage. The feed roller array has a pair of rollers supported on shafts for rotation and mounted with one superposed generally above the other. The upper roller is driven in a transport direction by a drive mechanism acting on an end of its shaft. The opposite ends of the shafts of the two rollers are journaled in frame members with the lower roller being supported for limited independent movement toward and away from the upper roller. The lower roller is normally biased into contact with the upper roller and is adapted to be displaced vertically away from the upper roller by a cam arrangement acting on the ends of its shaft. The upper roller is adapted to be shifted axially to disengage an end of its shaft from its journal to permit the upper roller to be removed manually from the apparatus.
