ABSTRACT:
Apparatus is described for the processing of a film contained in a cassette. The cassette comprises a substantially cylindrical body formed with a light-tight, longitudinally extending film exit slot, end caps to the body and a spool held between the caps and having the film wound thereon. The apparatus comprises a light-tight enclosure, preferably in the form of a columnar body, provided with means shaped to receive and retain the cassette body and provided with a space sufficiently large to receive from the cassette the spool with the film wound thereon. A plunger is provided for engaging the spool of the cassette and for moving it to force an end cap off the cassette body and to move the spool and the film wound thereon into said space where the film can be treated with processing liquid. The processing liquid may be present in the space or can be introduced into it and drained from it through light-tight channels and/or passages. The plunger may pass through a lid of the enclosure or be fixed to it. Rotation in both directions of the plunger in the apparatus causes the film to wind and unwind in the spool and to be washed evenly with processing liquid.
