PURPOSE:To improve the radiating property with a larger stroke of a printing wire by arranging the printing wire almost at the center of a plate spring with one end thereof fixed and the other end thereof pivoted on a mobile core of an air-core coil to move the mobile core along the length of the spring. CONSTITUTION:A printing wire 3 is welded on the plate surface of a long and narrow plate spring 2 on the side facing a platen 9 almost at the center thereof. One lengthwise end of the plate spring 2 is retained with a support 1 and the other end thereof is pivoted at the tip of a mobile core 4 inserted into an air- core coil 5 through a link 6. The mobile core 4 is provided lengthwise with respect to the plate spring 2 and as the mobile core 4 moves downward, the plate spring 2 springs up, projecting the wire 3 to the platen 9. |
