摘要： In a drive unit and a drive method for liquid ejection head, a voltage applied to a piezoelectric thin film has an electric potential stable period in the course of returning from an electric potential, when pressure chamber has contracted for the ejection of liquid, such as ink, to another electric potential prior to a drive for the next ejection. Intermittently disconnecting a circuit during residual vibration of meniscus suppresses changes of the electric potential. Deformation of the piezoelectric thin film and vibrations of the diaphragm are also suppressed. Compliance of the diaphragm and the natural vibration period Tc of pressure chambers are decreased. A significant effect can be obtained when using a piezoelectric thin film. Thus, a liquid ejection head drive unit and drive method are provided which effectively suppress the vibration of meniscus with a simple configuration and apparatus. The diaphragm can be sufficiently deflected during liquid ejection and the residual vibrations can be rapidly attenuated after the ejection.
