ABSTRACT:
An apparatus for processing photosensitive materials, which comprises: a tank through which a processing solution is pumped; a rack having 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; means for filling the small volume and the circulating means, from the lowest elevation point of the small volume and the lowest elevation point of the circulating means, with processing solution to prevent air from being entrapped in the processing apparatus; and means for emptying the small volume and the circulating means, from the lowest elevation point of the small volume and the lowest elevation point of the circulating means, of processing solution to prevent processing solution and particulate matter from being entrapped in the processing apparatus.
