description PURPOSE:To make the rate of enlargement bigger and to make therewith structure of a printing head compact by a method wherein a spring member with a piezoelectric element connected thereto at its other end, a first lever that is extending toward the other end of a fixing base plate with the spring member connected thereto at its other end, a second lever that is connected to the other end of the fixing base plate with the first lever connected thereto at its other end and a printing wire connected to the second lever are provided. CONSTITUTION:One end of a first lever 4 is connected to one end 2a of a fixing base plate 2, and the other end of a spring member 3 is connected to the lever 4. One end of a second lever 5 is connected to the other end 2b of the fixing base plate 2, and the other end of the lever 4 is connected to the lever 5, and a printing wire 6 is connected to the other end of the lever 5. As voltage is applied to an electrode of a piezoelectric element 1, the other end 1b of the piezoelectric element 1 moves diagonally toward upper left by longitudinal piezoelectric effect, and thereby the curvature of the spring member 3 becomes large, making the angle of the lever 4 to its original position widened by theta1, and the angle of the lever 5 to its original position is widened therewith by theta2, making the front end of the printing wire 6 displaced upward. As the above-mentioned is a structure of two-stage enlargement, the rate of englargement can be made sufficiently large.
