Abstract
A piezoelectric actuator device adapted for use in a printing machine and comprising a piezoelectric assembly and a movement magnifying mechanism for magnifying the movement of the piezoelectric assembly and for transferring the magnified movement to the printing wire. The movement magnifying mechanism includes a rigid member, a first spring connecting the second end of the piezoelectric assembly to the rigid member, and a second spring connecting the rigid member to the support base. A vibration absorbing means preferably comprising silicone rubber resin is inserted between the first and second springs to damp the vibration of the movement magnifying mechanism.
