PROBLEM TO BE SOLVED: To solve the problems that correction means in a pressure controller of a conventional dispenser determines a pressure target value by using correction means of the same setting and an initial correction value when the correction value is reset simultaneously as detaching a barrel, and the barrel is replaced with a new barrel, however, when the pressure target value is determined to perform a discharge process with the initial correction value as it is for many times, it is difficult to achieve quantitative discharge even when the above correction is performed in accordance with variation of room temperature, humidity, etc.SOLUTION: In a pressure controller of a pneumatic dispenser, a quantitative discharge pressure controller has: input means for inputting discharge liquid variation in the pressure controller; calculation means for calculating a pressure target value after that from the variation; changing means for changing a pressure command value into the pressure target value; means for storing the pressure target value; and learning correction means for correcting the pressure command value so that the pressure target value becomes the stored pressure target value in a discharge process after replacing barrels. |
