ABSTRACT:
In order to provide an ink jet print head effectively ensuring a stable print quality or capable of reducing the voltage applied to piezoelectric: elements while maintaining the volume displacement of the pressure chambers, and to provide an ink jet printer using the same, the ink jet print head of the present invention comprises a plurality of pressure chambers circularly arranged in a hounds tooth manner for allowing the passage of ink, and a plurality of ink flow paths acting as flow paths for ink flowing from the pressure chambers. It further comprises a diaphragm defining one surface of the pressure chambers, and a plurality of piezoelectric elements which apply a pressure to the pressure chambers to discharge the ink within the pressure chambers from the nozzle through the ink flow paths for printing. The pressure chambers disposed in the external portion of the hounds tooth arrangement have a circumferential length equal to or greater than that of the pressure chambers disposed in the internal portion of the hounds tooth arrangement, and have a radial length equal to or smaller than that of the latter.
