  • Patent number: 6158904
    Abstract: A carriage has a support shaft for supporting a plurality of film rolls and can be closed by a light shield cover to place the film rolls in a light-shielded state. A film roll storage mechanism is disposed in a dark room and has a shank for receiving the film rolls from the carriage. The film roll storage mechanism can transfer the film rolls one at a time from the shank onto a film unwinding shaft. A positioning mechanism positions the support shaft and the shank coaxially with each other and locks the carriage with respect to the film roll storage mechanism.

  • Patent number: 5579073
    Abstract: A compact integrated system for film and print processing has chemical processing trays, sink, water filter and faucet, chemical storage, and drying screens integrated into a single multi-purpose unit. The wheeled chemical processing trays are vertically stacked and rolled in horizontal corrugations traversing the length of the sink. A print under development is directly transferred vertically between chemical processing trays across a print sponge with a print gripper. Each print is uniformly processed in a chemical processing tray by rolling the tray, ensuring uniform distribution of the processing chemical without manually agitating the print. The water rinse step of the print development process is accomplished in an oscillating wash bath wherein the water is continuously circulated over and between the prints being rinsed. Each of the processing chemical trays may be angled downward for emptying into a basin which can also provide a sink as well as safe recycling/disposal following print processing.
