Title: Driving method for capacitive actuator and driving method for ink jet recording head
Inventor: SAKAI MARI
IPC: B41J2/055
Filed: 1997-04-21
Abstract: PROBLEM TO BE SOLVED: To drive a piezoelectric vibration element while suppressing the inrush current without prolonging the driving time. SOLUTION: A piezoelectric vibrator is formed on the surface of a resilient plate and a physical action is imparted to a driven body by applying a driving voltage to the piezoelectric vibrator thereby charging/discharging an actuator. A driving voltage v1 having a low time variation rate is applied in the initial charging state where the capacitance is high in order to suppress inrush current. When a voltage V1 is reached and the capacitance is lowered, the actuator is charged with a driving voltage v2 having a high time variation rate thus making constant the time to be elapsed before a specified voltage V2 is reached.
