Document Type and Number:

WIPO Patent Application WO/1992/001244

Kind Code:

A1

Abstract:

A plurality of processing tanks filled with a liquid for processing silver halide photosensitive material are provided side by side, in which processing is performed with a replenisher supplied in proportion to the quantity of the photosensitive material to be processed. Crossover rollers are provided between processing tanks for conveying said photosensitive material, and rinsing tanks filled with rinsing water are provided so as to immerse at least a part of each crossover roller into said water. In addition, at least a part of said rinsing water fed into each rinsing tank is used as at least a part of water required for diluting concentrated replenisher for processing liquid in a processing tank positioned in front of each rinsing tank. In this way, the quantity of developer or fixer to be replenished is decreased and thereby the quantity of waste liquid can be reduced. The crossover roller can be fully cleaned and special cleaning operation is not required, thereby enabling easy maintenance. The total quantity of water to be used can be reduced. Furthermore, excellent photographing functions such as freedom from physical uneveness in developing are available, and size reduction of the device as well as easy operation in preparing liquid is possible.
