On the other hand, when the diluting liquid is sent and the metering liquid sending pump of the desired original liquid stock tank is driven, the amount of the original liquid proportional to the number of revolutions is immediately sent from the discharge port of the pump. The whole amount is dispersed in a diluting solution, sent to a diluting solution together with the diluting solution, and stirred and mixed in the diluting tank. Then, at the time of stop, the flow of the diluting liquid and the sending of the original liquid are stopped in a state where the diluting liquid fills the liquid feeding pipe and the discharge port of the metering liquid feeding pump is immersed in the diluting liquid. In addition, the discharge port of the pump is washed with the diluent, and at the same time, the discharge port is prevented from being dried.
