ABSTRACT:
An ink droplet jet device having a piezoelectric ceramic plate is provided with ink chambers having partitions. The front half of each partition is opposite to the rear half in the direction of polarization. When a voltage is applied to the electrodes of a given partition, the front and the rear half thereof deform in the opposite directions because of their inverse directions of polarization. This prevents the introduction of air through the nozzles into the ink chambers adjacent to the activated ink chamber and the speed of printing is increased.
