ABSTRACT:
A processing apparatus has a processing chamber configured to receive a plurality of cylindrically-shaped film units. The film units comprise a plurality of film discs supported by a central aperture on an elongated shaft, in spaced relation and with the disc faces normal to the shaft axis, and end drive discs slightly larger in diameter than the film discs. The drive discs have a guide lug extending from their exposed sides and guide grooves are provided in the processing chamber interior. The first inserted film unit is directed into driving engagement with a drive means located at the lower portion of the chamber and subsequently inserted film units are directed into driving relation with the unit therebeneath. Processing fluids are sequentially introduced and discharged from the chamber with the film units rotating to effect film development.
