ABSTRACT:
An ink jetting device having plural ink channels whose volume is variable in accordance with deformation of piezoelectric elements, and a controller that applies a voltage to the piezoelectric elements and includes at least two timing generating circuits that oscillate timing signals for ink jetting with a time lag for a period that is shorter than the period from the time when the voltage is applied to the piezoelectric elements until the time when the voltage application is stopped, and a driving circuit that is provided in correspondence with each ink channel and serves to latch a signal representing whether ink jetting is performed and apply the voltage to the piezoelectric elements on the basis of the latched signal when receiving the signals from the timing generating circuits.
