ABSTRACT:
In obtaining an accurate mixing ratio of a liquid mixture, an actual mixing ratio of at least two different liquids mixed together is obtained, wherein the two kinds of liquids have a predetermined mixing ratio and are mixed by setting switching valves for the liquids. A mixing ratio error is calculated as a difference between the actual mixing ratio and the predetermined mixing ratio, and is stored. A switching timing of the switch valves is corrected based on the stored mixing ratio error.
