用されている。This 477,428 type printer is further divided into two types: those that use specific type, and wire dot printers that construct characters from multiple points without using type. Of these, wire dot printers use specific type. It is widely used in Japanese word processors that require a large number of characters.

されている。Printing wire 4 of such a wire dot printer...
As described above, because it is pressed toward the platen 7 via the armature due to the suction or release of the electromagnet, the tip is struck and an image is printed on the printing paper 8 while sliding on the printing medium such as the printer 9. Therefore, printing wires are required to have wear resistance, impact resistance, etc., and various materials have been developed, such as cemented carbide, powdered HSS, pure tungsten, or cobalt alloys. and used.
゛（発明が解決しようとする問題点）
しかし乍ら、従来公知の印字ワイヤ材料２例えば超硬合
金は、すべり、摩耗等に対しては強いが脆いため曲げモ
ーメントに対しては弱く折れが発生し易い。(Problem to be solved by the invention) However, conventionally known printing wire materials 2, such as cemented carbide, are strong against slipping and abrasion, but are brittle, so they are weak against bending moments and breakage occurs. Easy to do.
しかも、高価で比重が大きく（比重１４．０）ドツト時
のエネルギー消費が多くランニングコストも高くなる等
の不具合を免れない。In addition, it is expensive and has a large specific gravity (specific gravity 14.0), which causes problems such as high energy consumption during dotting and high running costs.
また、純タングステンは比較的安価ではあるが。Also, pure tungsten is relatively cheap.
超硬合金より更に比重が大きく（比重１９．２）。It has a higher specific gravity than cemented carbide (specific gravity 19.2).

更に、粉末ハイス（比重８．１５）或はコバルト系合金
（比重８，３）は２価格的には純タングステンより高い
が超硬合金よりは安く、シかも比重も小さい。Relatively high-speed printing is possible with around 7 or 9 wires, but in order to print complex characters like kanji, around 24 or 36 wires are required. For example, it was practically unusable as a printer for a Japanese word processor.0 Furthermore, powdered HSS (specific gravity: 8.15) or cobalt-based alloy (specific gravity: 8.3) are cheaper than pure tungsten. Although expensive, it is cheaper than cemented carbide and has a lower specific gravity.
従って９例えば粉末ハイス製２４本ワイヤ型プリンタの
印字速度は漢字のみの場合で約４０〜８０字／秒、仮名
混りの場合、約１２０〜２４０字／秒の高速印字が可能
であるため、現・在２４本或は３６本等ワイヤ本数の多
いプリンタの印字ワイヤの主流をなしている。Therefore, for example, the printing speed of a 24 wire type printer made of powdered high-speed steel is approximately 40 to 80 characters/second when printing only kanji, and approximately 120 to 240 characters/second when printing kana. Currently, it is the mainstream printing wire for printers with a large number of wires, such as 24 or 36 wires.

ものはなかった。However, in the case of powdered HSS or cobalt-based alloy,
When joining head parts (armature) - If soldered with silver solder, etc., brazing will undergo a phase transformation at temperature (approximately 700 to 800°C) and become brittle, so it is the strongest and most stable. Brazing is actually difficult to use, and mechanical joining methods such as caulking have to be used, and the joints with the head parts tend to come off. As mentioned above, any material
The material also has the abrasion resistance, impact resistance, and
There was no soldering device that satisfactorily satisfies all functions such as price, weight, etc.

しまうという問題がある。Additionally, automated equipment is mostly used to assemble the printing wire and armature. If assembly is performed automatically, weak printing wires may bend, causing errors in clamping the printing wire moving device, etc., and productivity is significantly hindered. Moreover, when a weak material is printed all the way through the guide 5, it cannot withstand the printing pressure and bends, getting caught in the guide 5 and losing its function.
本発明の目的は、自動組立にも十分耐え得る印字ワイヤ
全提供することである。The object of the invention is to provide a complete printing wire that is sufficiently durable for automatic assembly.
（間笛点を解決するための手段） 本発明者は、印字ワイヤの腰の強弱が、硬度。(Means for resolving the gap) The inventor has determined that the stiffness of the printing wire is determined by its hardness.
比例限度及びヤング率に依存していることを発見し、こ
れらの因子を向上させる手段を見い出した。We discovered that it depends on the proportionality limit and Young's modulus, and found means to improve these factors.
具体的に言えば、ビッカース硬度（ＨＶ２０１）を３０

0 or more, proportional limit by tensile test to 60' 9f/key 2
By setting the Young's modulus in the two cantilever bending tests to 25.000 and 9 f/N or more, a printing wire that can withstand automatic assembly can be obtained.
更に具体的に言えば、ビッカース硬度、比例限度、及び
ヤング率を上記した値以上にするために。More specifically, in order to make the Vickers hardness, proportional limit, and Young's modulus greater than or equal to the above values.

A dot printing test was conducted 100 million times. The test results are shown in Table 1 and FIG. Note that the diameter of the molybdenum alloy wire was 0.2 mφ.

を行った。After brazing at 845° C., it was fixed in an armature LT-clamp C as shown in FIG. 2, and a 90 degree bending test was performed. The proportional limit is the value of stress at the elastic limit measured by a tensile tester. Young's modulus was determined by a two-cantilever support bending test using an Amsler universal testing machine as shown in FIG.

０に９ｆ／ｗａ以下と低いことも認められた。From the above test results, it was recognized that the wear resistance was correlated with the Co content in the case of ZrO□ containing 1T. Furthermore, when the Co content is less than 0.05% and does not contain Z r O2, the wear amount may exceed 80 μm, and these have a low proportional limit of 45 kyf/■ and a Young's modulus of 20.00.
It was also observed that the power consumption was as low as 9f/wa or less.
また同様に、耐衝撃性では１本材料は軟らかく。Similarly, in terms of impact resistance, a single material is soft.

It was demonstrated that it was possible to obtain a strength of W2 or higher and that it could be sufficiently used as a printing wire for wire dot printers. Although omitted from the paper, a molybdenum alloy containing 0.05 to 5.0% by weight of other metals, oxides, carbides, nitrides, and nitrides could also be sufficiently used as a printing wire. .
