Abstract

PURPOSE:To print without using any ink ribbon and enable to accomplish simultaneous copying, by a method wherein a printing wire is constituted of a core member and a cylindrical member covering it, either one of said members is made of a hygroscopic material and an ink is infiltrated into it. CONSTITUTION:The printing wire 7 is composed of a solid core member 8 and the cylindrical member 9 covering it, either one of the two members 8, 9 is made of a right material such as tungsten, while the other one is made of the hygroscopic material such as felt. The ink is supplied into the hygroscopic material by spraying, impregnation or the like. For example, a free end 5a of an armature 5 is inclined toward a platen 1 by deenergizing an electromagnet 4, and the paper 12 is printed by advancing the tip of the wire 7. In this case, even when a carbon paper is inserted to accomplish simultaneous copying, the copying is effected securely by the rigid member (e.g., the member 8) of the wire 7, whereas the outermost paper is printed with the ink infiltrated in the hygroscopic material.
