Abstract
A low volume photographic material processing apparatus that utilizes a narrow horizontal processing channel with an upturned entrance and exit to contain processing solution within the channel. The apparatus accurately maintains the processing solution level by keeping the upper surface of the processing solution below the high impingement devices solution exit.
Claims12
An apparatus for processing photosensitive materials, said apparatus comprising:
- a processing module comprising a container, at least one processing assembly placed in said container and at least one transport assembly disposed adjacent said at least one processing assembly, said at least one processing assembly and said at least one transport assembly forming a substantially continuous channel through which a processing solution flows, said at least one processing assembly and said at least one transport assembly substantially filling said container and being dimensioned so that a small volume is provided for holding and moving processing solution and photosensitive material through said processing module, at least one discharge opening is provided in said at least one transport assembly or said at least one processing assembly for introducing processing solution through said channel;
- means for circulating the processing solution from said small volume in said module to said at least one discharge opening;
- means for managing processing solution volume in order to reduce the formation of processing solution disturbances;
- and
- means coupled to said circulating means for maintaining the processing solution level in a small volume at a predetermined level.

An apparatus for processing photosensitive materials, said apparatus comprising:
- a processing module comprising a container and at least one processing assembly place in said container, said at least one processing assembly form a channel through which a processing solution flows, said channel having an entrance and an exit and at least one discharge opening is provided in said at least one processing assembly for introducing processing solution to said channel;
- transport means for transporting the photosensitive material from the channel entrance through said channel to the channel exit, said transport means being disposed adjacent said at least one processing assembly and forming a portion of said channel, said container, said transport means and said at least one processing assembly are dimensioned so that a small volume is provided for holding and moving processing solution and photosensitive material through said processing module;
- means for circulating the processing solution through the small volume providing the said processing module;
- means for managing processing solution volume in order to reduce the formation of processing solution disturbances;
- and
- means coupled to said circulating means for maintaining the processing solution level in a small volume at a predetermined level.
