Abstract

PURPOSE:To obtain the captioned structure which allows a bimorph to fly freely, consumes little power, gives a large stroke action and has simple structure. CONSTITUTION:According to a signal for the print to be recorded, voltage is impressed selectively on a piezoelectric body 2. By this impression, a bimorph 2' composed of the piezoelectric body 2 and a metal plate 1 is curved sharply forwards. On the occasion, by the effect of an inertia energy conserved in the bimorph 2', the bimorph 2' is let to fly freely forwards, surpassing the force of a spring 5. Thus, it strikes against recording paper 10 through an ink ribbon 9 at the tip of a print wire 4, thereby dot printing being performed.
