装置。 multiple pressure chambers, each with a nozzle at one end;
an ink chamber that supplies ink to the pressure chamber and has an ink hole opening on an outer surface; a printer head that includes a plurality of piezoelectric ceramics bonded to the outer surface near each of the pressure chambers; an ink reservoir that is fixed to a certain outer surface and that stores ink that supplies ink from the ink hole to the ink chamber; and an ink reservoir that selectively drives the piezoelectric ceramic to apply pressure to the pressure chamber and selectively supplies ink from the nozzle. In the inkjet recording device, the piezoelectric ceramic has a first portion having a polarization direction substantially perpendicular to the outer surface of the printer head, and one end adjacent to one end of the first portion. a second portion having a polarization direction opposite to the polarization direction of the first portion; and a second portion having one end adjacent to the other end of the first portion and having the same polarization direction as the polarization direction of the second portion. An inkjet storage device comprising: a third portion having a third portion having a third portion having a third portion having a third portion having a third portion having a third portion having a third portion having a third portion having a third portion having a third portion having a third portion having a third portion having a third portion having
