PURPOSE:To reduce the rebound of a rocking lever, by providing a stopper having a shape increasing a contact area as the rocking lever for protruding a wire is pressed gradually. CONSTITUTION:When a current is supplied to a copper wire 16, magnetomotive force is generated and the movable core 26 being the movable part of a closed magnetic path is attracted toward a coil core 14 and, therefore, an armature lever 23 revolves around the engaging part with a post 21 and the wire 10 fixed to the armature lever 23 moves toward the surface of paper to print a dot and returns to a stand-by state by an armature return spring 22 after printing. A stop part at the time of return is a stopper 27. This stopper 27 is made of rubber and integrated with a stopper metal jig 28 by baking, and the leading end part of the stopper 27 and the surface of the armature lever 23 are inclined by an angle theta. |
