Inkjet head and inkjet printer |
摘要 |
An inkjet head in which cross-talk between adjacent pressure chambers is suppressed. The inkjet head has a channel unit having pressure chambers and nozzles communication with the pressure chambers, and an actuator unit fixed to one surface of the channel unit for changing the volume of the pressure chamber. The actuator unit includes individual electrodes provided opposed to the plurality of pressure chambers for receiving a drive signal to change the volume of the pressure chamber; a common electrode provided over the plurality of pressure chambers; a piezoelectric sheet provided between the individual electrode and the common electrode; and an independent electrode provided between adjacent individual electrodes and electrically isolated from the common electrode and the individual electrodes. An inductor is electrically connected between the independent electrode and a portion whose electric potential is substantially the same as that of the common electrode.
