PURPOSE:To make an operation simple and compact, further to contemplate a weight lightening, and to improve a durability and a printing character by providing an inlay body which is inlayed a hard material in a dot wire body, and an engaging section which can be engaged by a screw fastening, a fitting, a calking and the like to the dot wire mounting section of an armature formed at a rear end outer periphery of the dot wire body. CONSTITUTION:A dot wire 12 is positively fixed to a dot wire mounting section 16 of an armature 11 by a soldering, metallic bond, calking and the like, so that it can not be disconnected from there, after the dot wire is fastened with a screw to a threaded section 19 formed as an engagement section at the dot wire mounting section 16 of a dot wire supporting member 14 of the armature 11. A machining of the engage means such as the screw, a serration, and the calking and the like to the dot wire body is easy, since the dot wire body is made of materials such as nickel group alloys, maraging steels which are easy to manufacture, hard to break, and obtainable a necessary hardness, and high elastic material named Erujiroy popularly, and stainless materials and the like. |
