PROBLEM TO BE SOLVED: To supply the accurate amounts of respective liquids to a mixing apparatus even when there are three or more liquids and by any mixing ratio, and to mix coating materials by a highly accurate mixing ratio. SOLUTION: A plurality of cylinders of a cylinder pump 2 driven by a servo motor for discharging a fixed quantity corresponding to a pulse number are connected and simultaneously driven, the liquids supplied from a supply liquid container into the respective cylinders are discharged in a discharge process, respective discharge paths are communicated with a mixer 1 through respective switch valves, and the other paths of the switch valves are configured to return flow to the supply liquid container of the respective cylinders. The switch valve is controlled so as to perform discharge to the mixer side during the pulse number corresponding to the required discharge amount of the respective liquids and to return the flow to the supply liquid container during the other case in the discharge process. After supplying the respective liquids to the mixer, they are mixed and agitated by an agitation means. COPYRIGHT: (C)2011,JPO&INPIT
