Abstract

PURPOSE:To simplify the device and increase its operating speed, in a printing head for a wire dot printer of electrostriction-type wire driving system, by employing such a design as to fix the wire onto the top of a bimorph type electrostriction oscillator formed into an isosceles triangular shape. CONSTITUTION:A bimorph type electrostriction oscillator 1, which is composed of a metallic sheet 2 and two piezoelectric conversion elements 3 and 4 joined to both sides of the metallic sheet 2, is formed into an almost isosceles triangular shape, and a wire 6 is fixed onto the top. When a voltage is applied onto the side of a terminal 9, the piezoelectric conversion element 4 on the rear side displaces in the direction of contraction, and the top of the metallic sheet 2 displaces and moves from a stationary position N to a resting position 1. When the switching is made from a to b by a switching circuit, the piezoelectric conversion element 3 on the front side displaces in the direction of contraction, the top of the metallic sheet 2 displaces and moves from the resting position 1 to a printing position 2, and printing motion is performed by the wire 6.
