摘要： The present invention is directed to a method for driving a piezoelectric ink jet head comprising a piezoelectric actuator AC that includes two piezoelectric ceramic layers 7a, 7b having such a size that covers the plurality of pressure chambers 2, wherein an electric field of opposite sense to the polarizing direction is applied to the second piezoelectric ceramic layer 7b by using the common electrodes 8a, 8b and, (1) for the pressure chambers 2 from which the ink is discharged, an electric field of the same sense as the polarizing direction of the layer is applied to the first piezoelectric ceramic layer 7a by using the individual electrode 10 and the first common electrode 8a, thereby causing the region of the piezoelectric actuator AC to deflect toward the pressure chamber 2, while (2) for the pressure chambers 2 from which the ink should not be discharged, an electric field of the opposite sense to the polarizing direction is applied to the first piezoelectric ceramic layer 7a by using the electrodes 10, 8a, thereby to maintain the region of the piezoelectric actuator AC in the initial state, so as to discharge an ink droplet selectively through the nozzle 3 that communicates with the pressure chamber 2 described in (1) and form a dot.

摘要： The present invention is directed to a piezoelectric ink jet head wherein the partition walls that separate the adjacent recesses that make the pressure chambers are formed to have such a cross sectional shape as the width W1 in the planar direction at the upper end on the side of the substrate where the drive section is formed and height H in the direction of substrate thickness satisfy the expression (1): W1≧H (1) while the width W1 and W2 of the lower end at the bottom of the recess of the substrate in the planar direction satisfy the expression (2): W1≦W2 (2) in order to prevent the dot size and dot shape of the picture to be formed from varying as the state of driving the individual drive regions or the state of driving the individual piezoelectric elements are influenced by the state of driving the other plurality of drive regions or the state of driving the individual piezoelectric elements that surround the former.
