Abstract
Improvement in a wire for a dot printer. The wire is made of a very tough base metal with a very hard, highly wear-resistant film coated onto the base metal. The conventional wire of this type has the technical problem that irregular wear is produced when it is used in a dot printer, this problem is eliminated by covering the base metal with the film.

A ring-shaped permanent magnet fixed to the rate 1, 4 magnet coils respectively fitted to the plurality of cores 2, and 5 at positions facing the plurality of cores 2, respectively. A second plate having holes 5a and forming a common magnetic path. Rate, 6 is a spacer, 7 is a force at one end, connected in a ring shape, the second frame. A plate panel having a hole 7a opposed to the hole 5a of the plate 5 and divided into a plurality of pieces and provided with end portions 7b each of which can be independently biased, 8 is the plate panel 7' To tip 7 . A wire 9, which is fixed by a single attachment or the like, is attached to the hole 7a of the plate panel 7 to form a frame. The hole 5a in the base 5 and the armature o fixed against the core 2 A pin 10 is a guide frame, and 11 is a pin guide attached to the tip of the guide frame 10 to guide the wire. A guide member is formed by the arm 10 and the pin guide 11 .
前記構成の も のにおいて、 動作を説明する。 まず、 マグネ ッ ト コ ィ ル 4 に通電していない と き には永久磁 石 3 の磁力に よ り 板パネ 7 の端部 7 b のァーマチュア ン 9 がコ ア 2 に吸引 -される。 したがって、 こ の と き には前記板パネ 7 の端部 7 t> は偏倚されている。 次に 前記マグネッ ト コ イ ル 4 に通電する と該マ-グネ ッ ト コ ィ ル 4 に発生する磁界が前記永久磁石 3 の磁界を打消 すので前記板パネ 7 上のァ ーマチュアピ ン 9 がコ ア 2 に吸引されな く なる。 したがって、 前記板パネ 7 の端 部 7 ¾ は前記偏倚から解放され、 当該板パネ 7 の先端 に固着されたワ イ ヤ ー 8 は ンガイ ド 1 1 に案内され 駆動される。 次に前記マグネ ィ ル 4 の通電を断つ と前 記板パネ 7 の ァ ー マ チュ ア ピ ン 9 は前記永久磁石 3 の 磁力に よ り再び前記コ ア 2 に吸引される。 The operation of each of the above configurations will now be described. First, when the magnet coil 4 is not energized, the magnetic force of the permanent magnet 3 attracts the armature 9 at the end 7 b of the plate panel 7 to the core 2 . Therefore, at this time, the end portion 7t> of the plate panel 7 is biased. Next, when the magnet coil 4 is energized, the magnetic field generated in the magnet coil 4 cancels the magnetic field of the permanent magnet 3, so that the armature pin 9 on the plate panel 7 is engaged with the coil. It will not be sucked into A2. Therefore, the end portion 7 of the plate panel 7 is released from the bias, and the wire 8 fixed to the tip of the plate panel 7 is guided by the guide 11 and driven. Next, when the power supply to the magnet nail 4 is cut off, the armature pin 9 of the plate panel 7 is again attracted to the core 2 by the magnetic force of the permanent magnet 3 .

δ 題 と なっている。 Then force it to return the dot file as above. The wires in the printing head H for the linter are guided by the pin guide 11 and aligned substantially in a line, but the portion fixed to the plate panel 7 is arranged in a substantially elliptical shape. It is designed so that it contacts the printing surface at an angle of about 1 inch during printing. The problem is that the whole becomes obscure. It is a δ problem.

However, although these materials have excellent wear resistance, they are vulnerable to shocks and are difficult to weld, making it difficult to fix them to the plate panel. be. Therefore, it is desired to develop a superior wire for dot linter that eliminates these drawbacks. Invention disclosure
