Abstract
A print head for a piezoelectric ink jet printer includes a piezoelectric actuator in the form of a plate, which lies on one side of a metallic cavity plate. The actuator includes drive electrodes and side electrodes. The side electrodes are formed on a side face of the actuator and each connected with one of the drive electrodes. The cavity plate has pressure chambers each aligned with one of the drive electrodes. The cavity plate also has nozzles each communicating with one of the chambers. The cavity plate further has a recess formed on the one side. The side electrodes are aligned with the recess to be kept out of contact with the cavity plate. Another print head for a piezoelectric ink jet printer includes a piezoelectric actuator in the form of a plate, which lies on a cavity plate. The actuator has recesses formed in a side face of it, and includes drive electrodes and side electrodes. Each side electrode is formed in one of the recesses and connected with one of the drive electrodes.
