PURPOSE:To easily vary the discharge ratio of liquid agents and to adjust the ratio finely by connecting pumps to plural driving motors which rotate at rotational ratio set by a control means equipped with a ratio setting circuit capable of setting the pumps to an optional discharge ratio. CONSTITUTION:A control part 10 inputs the output signal of a reference voltage generating circuit 11 to a motor speed setting circuit 12 and a two-liquid metering ratio setting circuit 13. Then the output signal of the motor speed setting circuit 12 is inputted to a curing liquid-agent side motor pulse generation circuit 16 through a main-liquid-agent side pulse motor pulse generation circuit 14 and the two-liquid-agent ratio setting circuit 13. Input signals to the motor pulse generating circuits 14 and 16 are converted into pulse signals, which are outputted to to a main-liquid-agent side motor drive circuit 15 and a curing liquid-agent side motor drive circuit 17. The reference voltage generating circuit 11 outputs a reference voltage for determining the discharge speed of a liquid agent as its output signal and its value is optionally settable by an operator.
