(2) Background of the technology A wire guide for a wire dot printer is included in the print head shown in FIG. A second support plate 3 and a wire guide 4 that support the tip of the wire l in a straight line are provided in parallel in sequence. Here i
The tips of the wires are arranged in a straight line &, but they may also be arranged in a staggered manner. The wire guide t is provided to prevent lateral vibration of the wire during printing, and is required to minimize mutual wear between the wire and the guide due to friction with the wire.

The printing wire has a diameter of, for example, 0.35 m1, and the pitch of the wires on the guide is narrow, for example, 0.47 sieves, so it is impossible to perforate each piece of hard material with such high precision. The disadvantages are that the work is complicated and the product is expensive.

(4) Purpose of the invention The purpose of the present invention is as follows: 1. The purpose is to eliminate the above drawbacks1.
(5) Structure of the Invention The above object of the present invention is to fill a castable resin with at least wear-resistant particles, and to apply this resin to a plurality of wires having a diameter slightly larger than the diameter of the guide wire. After pouring into a mold with drawing wires arranged inside and allowing it to harden, the mold is released and the wires are pulled out to form a block with holes [2. This block is cut perpendicular to the direction of the holes. C1 can be achieved by a method of manufacturing a plurality of wire guides having a predetermined thickness.

Nine pieces were arranged in a row. A mold release agent was applied to this, and the resin mixed earlier was injected into the mold and cured. After releasing the mold, the tungsten wire is pulled out from the hardened block, and the shape of the block is adjusted to the specified T1 method by polishing to produce the perforated block 7 shown in Fig. 3, which is cut to the specified thickness using a wire saw. The wire guide 4 shown in FIG. 4 was manufactured in multiple pieces by slicing. After polishing both main surfaces of this wire guide 4, it was mounted on a print head equipped with a printing wire 9 having a diameter of 0.35 fi, and a printing test was performed at a speed of 180 characters/second.
