Abstract
A piezoelectric printing head includes an annular base frame and a plurality of piezoelectric actuator assemblies mounted on the base frame. Each actuator assembly includes a piezoelectric element having one end rigidly secured to the base frame and another free end, an armature having a base end and a tip end to which a printing wire is rigidly connected, and a magnifying mechanism. When the piezoelectric element is electrically energized, a displacement of the piezoelectric element is magnified and then transmitted to the printing wire. Between the base frame and the base end of the armature there is provided a vibration damping buffer member.
