PURPOSE:To make the instantaneous outflow of a developing replenisher proper and reduce the time required to supply the replenisher by producing a negative pressure state in the lower edge part of the tube of the liq. feeder of a copying machine in a moment at the time of opening the value of the feeder to accelerate the forced outflow of the replenisher. CONSTITUTION:Liq. feeder body 1 is composed of grip section 3 screwed down on discharge section 5a of replenishing tank 5, tube 4 piercing through the central part of section 3 and value unit 6 liftably placed in tube 4. After attaching tank 5 to a developing section, by moving stopping piece 6c of unit 6 into unit 6 against spring 6b, ringlike lip 6d2 of value 6d is separated from the inner edge of tube 4 and pulled out of the opening of tube 4. At this time, a negative pressure state is produced in the tightly sealed inner edge part of tube 4 fo force a replenisher to be sucked into the outside of valve 6d. Thus, the instantaneous forced outflow of the replenisher is accelerated. |
