Abstract
A printing head provides an array of stylii and stylii drivers for forming characters in accordance with a desired matrix of dots. Each driver comprises a flat piezoelectric ceramic wafer and a levered beam having a stylus secured to one end and providing at the stylus end a multiplication of the movement of the wafer of approximately 4 to 1 to 7 to 1. The wafers and supporting structure are circular and structured to nest preferably coaxially, with each levered beam lying at a small angle relative to its adjacent beams so that the printing ends of the stylii may be constrained to lie along a straight line perpendicular to the direction of movement of the head.
