Abstract
PURPOSE:To improve the unstable working of an actuator driven by a piezoelectric element that is caused by the temperature change, by detecting the temperature of the piezoelectric element and controlling a heating unit which heats up the piezoelectric element based on the detected temperature of the piezoelectric element. CONSTITUTION:A temperature controller 11 supplies the temperature detection signal detected by a temperature sensor 8 from an A/D converter 10 and compare the detection signal with a reference temperature Ts. When the detected temperature Tm is lower than the temperature Ts, a transistor (TR) 13 is turned on to start energization to a heater 12. Then the TR 13 is turned off and the energization is cut off to the heater 12 when the Tm is higher than the Ts. As a result, the temperature of a piezoelectric element 2 never exceeds the temperature Ts. Thus an actuator performs the stable working.
