にドツトを打つ印字動作を行なう。FIGS. 1(a) and 1(bl) are a perspective view and a side view, respectively, of a conventional impact print head.
The print head shown in ) has a plurality of printing units l arranged and attached to one end of the head stand 2, and a pin 11 fixed to the end of each printing unit l is provided at the other end of the mounting member 2. Each printing unit 1 is configured by passing through the guide holes of the alignment member 21 and aligning them.As shown in FIG. A pin 11 for printing dots is attached and fixed to one end of a piezoelectric vibrator which is fixed and further has conductor electrode plates 51 and 52 fixed to both outer surfaces thereof, respectively. Electrode plates 51 and 52 are connected to one of a pair of conductive wires 6 via metal attachment member 2, and electrode plate 50 is connected to the other conductive wire 6. The piezoelectric plates 41 and 42 have been polarized in advance, and when a driving voltage is applied between the electrode plates 51 and 52 and the electrode plate 5o via the conductor 6, the piezoelectric plates 41 and 42 are polarized due to the piezoelectric transverse effect. The piezoelectric plate 42 contracts and causes a strain in the direction of the broken line arrow A, and the piezoelectric plate 42 expands and causes a strain in the direction of the broken line arrow B. Along with this, the piezoelectric vibrator is deflected, and the pin 11 moves in the direction of the broken line arrow C, thereby performing a printing operation of striking dots on the printing surface.

めには大きな駆動電力（約５倍の電力）を必要とする。As explained above, the conventional impact print head has the disadvantages of large size and high power consumption.In other words, the printing unit 1 used in the conventional impact print head has the disadvantages of large size and high power consumption. The printing operation is performed by generating dimensional distortion in the piezoelectric body using the piezoelectric transverse effect, but compared to the piezoelectric longitudinal effect, the resulting distortion is small (Poisson's ratio times, or approximately twice). ) Therefore, in order to store the specified mechanical energy, it is necessary to have a large lifetime volume (the square of the bore run number, that is, approximately 9 times the volume), and since the electromechanical coupling coefficient is small, in order to obtain the specified strain requires large driving power (approximately 5 times as much power).

ドの大形化は避けられない。In a conventional impact print head equipped with a plurality of printing units 1 that utilize such a piezoelectric transverse effect, each printing unit 1 is large in size as described above, and each printing unit 1 does not interfere with other printing during printing operation. They must be arranged with a sufficient distance from each other so as not to come into contact with the unit 1, and an increase in the size of the print head is unavoidable.
