PURPOSE:To enhance the reliability and durability of a printer and to attain to more accelerate the speed thereof, by a method wherein the projection part provided to a second lever is engaged with the recessed part provided to the second lever holding part in a base and an engaged part is supported in a pressure contact state by a spring. CONSTITUTION:An electrostriction element 101 is connected to a base 102 through a hinge 107 and to a first lever 103 through a hinge 108 while the first lever 103 is connected to the base 102 through a hinge 109 and to a second lever 104 through a hinge 110 and a wire 106 is connected 106 to the second lever 104 through an arm 105. In addition, a projection part 113 is provided to the part of the second lever 104 and engaged with the recessed part 118 provided to the second lever holing part 112 in the base 102 and the inlay part is supported in a pressure contact state by a spring 114. By this mechanism, the shaking of the engaged part is eliminated while the lever 104 is smoothly rotated and high speed printing with reliability can be performed. |
