PURPOSE:To enable the execution of printing without bringing a dot wire into contact with a wire guide by a method wherein either one of the dot wire and the wire guide is constructed of a magnetic material and the other of a superconducting material. CONSTITUTION:While a dot wire 2 is constructed of a magnetic material, a wire guide 3 is constructed of a superconducting material and the environment of the wire guide 3 is kept at a critical temperature of superconduction or below by an appropriate means. By a Meissner effect of the superconducting material constituting the wire guide 3, according to this method, a repulsive force is generated between the dot wire 2 and the wire guide 3, and the the dot wire 2 is made to pass through the central part of a guide hole 3a by the repulsive force and dose not come into contact with the guide hole 3a when it is inserted through and guided by the guide hole 3a. Accordingly, a problem of frictional heat or a frictional force caused by the contact of the dot wire 2 with the wire guide 3 is eliminated, and thus the execution of continuous printing for a long time and high-speed printing is enabled. |
