Abstract
A processing apparatus is provided for immersion treating a photograhic film unit with a low viscosity processing liquid. The apparatus comprises a flexible bag-like liquid container having a film unit receiving section and a communicating liquid reservoir section, and a device for manipulating the container to selectively change the configuration of the container and the distribution of liquid therein. The device includes a pivoting frame which moves components of the receiving section between an open position for facilitating film insertion and withdrawal and a closed position defining the receiving section which is flooded with liquid from the reservoir section to treat a film unit therein.
Claims13
Processing apparatus for treating a sheet-like film unit with a processing liquid, said apparatus comprising:
- a liquid container having a reservoir section and a pair of wall members coupled to said reservoir section and being movable relative to each other between a closed position, wherein said wall members cooperate to define a compliant film unit receiving section disposed in communicating relation to said reservoir section, and an open position wherein said wall members are spaced further apart than when in said closed position to facilitate movement of a film unit into and out of said receiving section, said liquid container being configured to hold a volume of processing liquid, at least sufficient to have a film unit immersed therein, which is selectively distributed within said container to establish a first condition whereby said receiving section is substantially dry and substantially all of the liquid is in said reservoir section, and a second condition whereby said receiving section is flooded with liquid from said reservoir section to immersion treat a film unit therein;
- means for supporting said liquid container;
- means operable for selectively moving at least one of said wall members relative to the other between said open and closed positions;
- and
- pressure applying means operable when said wall members are in said closed position and configured to engage the exterior of said compliant receiving section for selectively pressing portions of said wall members against a wet immersion treated film unit therein to squeegee excess liquid from the film unit.
