Abstract:
In accordance with an embodiment, an inkjet head comprises a pressure chamber, an actuator, a nozzle plate, and a head drive circuit. The pressure chamber accommodates ink. The actuator is arranged in correspondence with the pressure chamber. The nozzle plate has a nozzle communicating with the pressure chamber. The head drive circuit applies a drive pulse signal, which includes a first pulse for returning a volume of the pressure chamber after expansion, a second pulse for returning the volume of the pressure chamber after contraction, and a third pulse for returning the volume of the pressure chamber after contraction, to the actuator in such a manner that the second pulse is applied without providing a standby time before the first pulse, and the third pulse is applied without providing the standby time after the first pulse.

Claim (Index 9):
A driving method by an inkjet head, comprising:\n applying a drive pulse signal, which comprises a first pulse for expanding and then returning a volume of a pressure chamber after expansion, a second pulse for contracting and then returning the volume of the pressure chamber after contraction, and a third pulse for contracting and then returning the volume of the pressure chamber after contraction, to an actuator provided corresponding to the pressure chamber for accommodating ink so that the second pulse is applied without providing a standby time before the first pulse, and the third pulse is applied without providing the standby time after the first pulse; and discharging ink droplets from a nozzle communicating with the pressure chamber corresponding to the actuator.
