Abstract
When gears which drive rollers for transporting photographic printing paper are rotated to thereby transport the photographic printing paper, shutters retract from a photographic printing paper passage and rollers rotate so that the photographic printing paper is transported. When the gears are reversed after the completion of the transport of the photographic printing paper, the shutters block the photographic printing paper passage and are located above the rollers which protrude in the photographic printing paper passage to thereby prevent floating materials such as silver, sulfide, soiling and the like from precipitating on the surfaces of the rollers.
Claims16
A photosensitive material processing apparatus comprising:
- a processing tank for processing a photosensitive material by immersing said photosensitive material in a processing solution contained therein;
- feed rollers provided in said processing solution for nipping and transporting said photosensitive material;
- and
- shutters retractably provided above said feed rollers in said processing solution.
A photosensitive material processing apparatus comprising:
- a processing tank for processing a photosensitive material by immersing said photosensitive material in a processing solution contained therein;
- feed rollers provided in said processing solution for nipping and transporting the photosensitive material;
- a photosensitive material feed path provided in said processing tank along which said photosensitive material passes;
- and
- shutters provided retractably with respect to the photosensitive material feed path situated above said feed rollers in said processing solution.
A photosensitive material processing apparatus comprising:
- a processing tank for processing a photosensitive material by immersing said photosensitive material in a processing solution contained therein;
- feed rollers provided in said processing solution for nipping and transporting the photosensitive material;
- a driving means for driving said feed rollers;
- and
- a control means for intermittently driving said driving means when the processing of a photosensitive material is not conducted.
A photosensitive material processing apparatus comprising:
- a processing tank for processing a photosensitive material by immersing the photosensitive material in a processing solution contained therein;
- feed rollers provided in said processing solution for nipping and transporting the photosensitive material;
- a circulation means for circulating the processing solution in said processing tank;
- and
- a control means for intermittently driving said circulation means when the processing of a photosensitive material is not conducted.
