Abstract

PURPOSE: To keep the vol. of a soln. in the separated soln. tank of a dry diazo copying machine constant by providing the tank with a float switch and carrying out control so as to introduce the soln. into the recovered soln. tank by a vol. exceeding a predetermined vol. and to evaporate a part of the soln.
CONSTITUTION: In a dry diazo copying machine a developing gas and an ammonia- free separated soln. are generated from an ammonia soln., ammonia in used developing gas passed through the developing chamber is recovered by absorption in the separated soln., and this recovered soln. is recycled for developing gas generation. The separated soln. tank of the machine is provided with a float switch, and when the surface of the soln. in the tank exceeds a predetermined height, the switch is actuated to open the bypass of the tank leading to the recovered soln. tank. Simultaneously the means for evaporating part of the soln. flowing out of an overflow duct is actuated. Thus, the vol. of the soln. in the separated soln. tank can be kept constant.
