Automatic replenishment, calibration and metering system for a photographic processing apparatus

摘要

A low volume photographic material processing apparatus that utilizes a tank having integral means through which processing solution is pumped and a rack which has integral means to facilitate its insertion and removal from the tank, the rack and the tank are relatively dimensioned so that a small volume for holding processing solution and photosensitive material is formed between the rack and the tank. The apparatus accurately maintains the processing solution level by keeping the upper surface of the processing solution below the high impingement devices solution exit.
