PURPOSE:To decrease number of the parts and the working amount by providing the bent part extended to the plate thickness direction and hardened and utilizing this part as the printing wire on the arm tip of the wire drive part made of magnetic material. CONSTITUTION:Wire driving member 6 as a whole is formed like the crank composed of the plural cut grooves 8, 9 along the radius direction and the cut groove 10 made nearly along the peripheral direction so as to connect the both grooves 8, 9. The cranklike formed parts 6e, 6c and 6b function as the armature part, the torsion spring part and the base part respectively. Also the bent part 6d of the inner end 6a composing printing wire, which is extended to the plate thickness direction and almost at right angle, is hardened. |
