Zusammenfassung:	Provided downstream of an on-off valve are a needle and a diaphragm that cooperates with the needle. The needle is driven by a motor. A controller causes the motor to move the diaphragm cooperating with the needle for increasing a volume of a flow path downstream of the on-off valve. Accordingly, this allows suck back, leading to prevention of drips of the processing liquid. In addition, the controller causes the motor to move the needle for regulating the flow rate of the processing liquid when the on-off valve is opened. This facilitates flow regulation of the processing liquid by the motor which is current1y made by the operator's sense. Moreover, since prevention of the drips of the processing liquid as well as the flow regulation of the processing liquid are performable with the same motor, a needless configuration is omittable to achieve space saving.
