Abstract
In photographic processing apparatus in which continuous processing is carried out in a tank having a low volume, it is difficult to obtain sufficient agitation of the processing solution. This problem arises because processing solution adheres to the emulsion surface of the material being processed access of fresh processing solution to the emulsion surface is restricted in the narrow confines of the tank. Described herein is an arrangement in which the agitation of the solution is improved. The arrangement includes an element (16) which is positioned over a feed slot (18) through which processing solution enters the tank (10). The element (16) serves to keep the emulsion surface of the material being processed away from the tank wall and allows access of processing solution to the emulsion surface.
