ABSTRACT:
A piezoelectric printer including: a frame; a plurality of printer units mounted on the frame; each unit including an asymmetric piezoelectric bender including one or more piezoelectric members and having a mounting portion and an actuating portion, the actuating portion being moveable in an actuating direction; the bender being tapered in its lateral dimension and being larger at the mounting portion and smaller at the actuating portion; first and second metal reinforcing layers externally mounted on said bender, the first on the side of the actuating direction, the second on the opposite side; and a printing element driven by the actuating portion; means for applying an actuating voltage to the bender in the poling direction for actuating the bender to drive the printing element to the printing position and guide means attached to the frame for guiding the printing elements; the printer units are arranged in sets of stacked arrays, which may be overlapped and may include holes in each of the inferior printer units for receiving printer elements from superior printing units.
