  • Patent number: 4690535
    Abstract: An automatic film processor arrangement is provided, which comprises a plurality of processing tanks each being charged with a processing liquid, and plural sets of a pair of rollers mounted within the respective processing tanks to continuously pass a photosensitive film through the processing liquids. Shafts projecting from both ends of the rollers are provided with sleeve-like bearings. Each bearing is formed on the inner face with a projection in the circumferential direction, is formed with a split groove extending axially from a mouth thereof which is open on the roller side, and includes opposing flat portions on the outer face. The bearing is locked in place by engaging its projection within the groove formed in the shaft of each roller. Each pair of roller are held by supporting the adjacent bearings by the lock plate on the same side.
