Abstract
Abstract A processing solution tank specifically adapted for an office-type microfilm processing apparatus in which the operation of changing the processing solutions is eased. The tank is divided into two sections, each of which is composed of plural processing vessels. The two sections are joined together by a hinge so that they can be folded together. A carrying handle is fitted to the main body of each of the two sections, and the two handles come together when the tank is folded. The height of the handles is such as to prevent the processing solutions in the two sections from mixing with one another.
