Title: Piezoelectric element driving circuit
Inventor: SAKAIDA ATSUO
IPC: B41J2/295
Filed: 1988-05-11
Abstract: PURPOSE:To improve the operation responsiveness of a piezoelectric actuator by allowing a displacement duration of the piezoelectric element to be set independently of a resonance cycle time. CONSTITUTION:First state control means made up of a transistor TR1, a diode D1, and a drive control device AC is set to a charge ready state with a drive command SS and is reset to a charge or discharge blocking state before a terminal voltage of a piezoelectric element P completes one cycle displacement. Although second state control means made up of a transistor TR2, a diode D2, a resistor R, and a drive control device AC is always in a charge ready state, it is brought to a discharge ready state after a predetermined time has passed from receipt of the drive command SS and is reset to the charge ready state by the time when the first control means is set to a next charge ready state. Thus, a displacement duration of the piezoelectric element P is set independently of the length of the resonance cycle time, thereby improving the operation response of the piezoelectric element P.
