Abstract
In order to increase the accuracy of dispensing liquid from a sealed liquid holding container without increasing device complexity, pressures inside and outside the sealed liquid holding container are measured with a pressure sensor connected to a dispensing probe, and the amount of discharge operation of a pump is corrected in accordance with the measured pressures. The amount of operation of the pump is corrected by calculating the amount of deformation of a dispensing flow passageway due to pressure change.
