【発明の詳細な説明】
本発明はデータ通信装置および情報処理装置における出
力機器として用いられるワイヤドツトプリンタのワイヤ
ガイドに関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a wire guide for a wire dot printer used as an output device in a data communication device and an information processing device.
かかるワイヤドツトプリンタのワイヤガイドにおいて、
その先端ガイド部は、プリンタ使用中作動している印字
ワイヤと接触摺動状態、となるため特に耐摩耗性が要求
され、フレーム部分は長期的な使用に耐え、かつ温度、
湿度等の環境に変化があってもｆ４Ｊ字面とめギャップ
を一定に保持しなけ扛はならないので、寸法安定性も必
要とされる。In the wire guide of such a wire dot printer,
The tip guide part must be especially wear resistant because it comes into contact with the printing wire that is in operation while the printer is in use, and the frame part must be able to withstand long-term use and be able to withstand temperature fluctuations.
Even if there are changes in the environment such as humidity, the f4J-shaped face stopper gap must be kept constant to prevent it from being removed, so dimensional stability is also required.
このため、従来はワイヤガイド全体を焼入鋼等の金め五

、コストも高くなるという欠点を有［−ていた。For this reason, in the past, the entire wire guide was made of gold metal such as hardened steel, or the tip guide part was made of ruby-containing ceramic and the frame part was made of metal. However, wire guides made of metal do not necessarily have sufficient wear resistance at the tip guide portion, and require time and labor to manufacture, making them unsuitable for mass production and resulting in high costs. Wire guides whose tip guides are made of ruby-containing shoulder ceramic have excellent wear resistance at the tip, but because of the bonding and manufacturing processes involved, they are more difficult to mass produce than metal-only wire guides and are costly. It also had the disadvantage of being expensive.

イヤガイド、である。The wire guide of the present invention has excellent wear resistance at the tip guide portion, and has excellent dimensional stability and durability as a whole.
Since it can be easily molded using a general plastic molding method, mass production and cost reduction can be achieved. It is made of a resin composition containing a fibrous base material and an inorganic powder base material, and the fibrous base material is selected from carbon fiber, silicon carbide fiber, metal fiber, aromatic polyamide fiber, and polyacetal resin. A wire guide for a wire dot printer, which is characterized by:

向上し、ワイヤガイドの先端ガイド部として金属と同等
以上の特性を有するものとなる。In the wire guide of the present invention, at least the tip guide portion is molded from a wear-resistant resin containing a fibrous base material. When a fibrous base material is added as a reinforcing material, the wear resistance is further improved, and the tip guide portion of the wire guide has properties equal to or better than those of metal.

定性が向上する。Historically, in the present invention, inorganic powder can be used in combination as a reinforcing material. This inorganic powder base material is not particularly limited, but silica, alumina, glass, silicon carbide, etc. are preferable. By adding these inorganic powder base materials, wear resistance, heat resistance, thermal conductivity, and dimensional stability are improved.

（好ましくは５〜１５％）である。Regarding the blending amount of these reinforcing materials, the fibrous base material should be 5750% (weight f%, the same hereinafter) of the entire composition, preferably 10 to 40%. Fibrous base material accounts for 5 to 40% (preferably 10 to 35%), and inorganic powder base material accounts for 5 to 20% of the entire product.
(preferably 5 to 15%).
フレーム部は前記先端ガイド部と同じ材料を使用するこ

。In order to manufacture the wire guide of the present invention, injection molding,
Plastic molding methods such as transfer molding can be used. When the tip guide portion and the frame portion are molded from different materials, the tip guide portion is first molded 2 and then the other portions are molded, or vice versa. In this case, the purpose of the present invention is to improve mass productivity and reduce manufacturing costs, so it is most effective to use the so-called two-color molding method.
An insert molding method for molding the second part is also possible.
