Abstract

PURPOSE:To enable high speed driving with the charging of small energy by driving a hammer of an impact printer utilizing a capacitive electrostrictive element and an Yieden spring mechanism. CONSTITUTION:An electrostrictive element 1, a member 1a for the element to be connected to a frame and a working member to be connected to a spring 5 are combined to form an electrostrictive section 6a and the spring 5, a striking section 3 and a spring 4 form an expanded convertion section 6b. One end of the spring 4 is bent at the right angle and clamped to the frame with a member 7 through a spacer 8. The member 1b and the spring 5 are parmanently combined together at the ends thereof. The extended section 1c of the member 1b is arranged along the spring 5 and lightly contacts the side of the spring 5 near the fastened section with a beam 2 with a clearance in the course thereof.
