Abstract
It is known to apply processing solution to photographic material using a high speed moving surface. High speed rotating drums have been used to transfer processing solution from a reservoir to the material. Horizontal belts are also known. However, such arrangements require large volumes of processing solution in order to operate effectively. Described herein is a processor comprising a vertically mounted high speed belt which both transfers processing solution from a reservoir onto photographic paper being processed, and provides agitation at the paper surface. Two transport belts are provided, one on either side of the belt to assist in the transport of paper through the apparatus. An arrangement according to the invention has the advantages that only low volumes of processing solutions are required, good surface agitation is provided, and it can be fitted into conventional photographic processing apparatus.
