ABSTRACT:
Disclosed is a method of supplying replenishing solution in an automatic developing machine which processes exposed film by means of pump. A time required for the pump to operate is determined using a discharge rate of the pump and a total quantity of replenishing solution to be supplied which is determined in accordance with the amount of exposed film to be processed, and the pump is continuously operated accordingly in that operating time. In consequence, a small size pump can be employed, and the variations in pump discharge rate can be compensated for by controlling the operating time of the pump.
