本発明はワイヤドツトプリンタ用の印字ヘッドに関し
特に該印字ヘットを（Ｒ成するコイルの組立性を向上す
るのに好適な印字ヘッドに関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a print head for a wire dot printer.
In particular, the present invention relates to a print head suitable for improving the ease of assembling the coils that make up the print head.
第１図は従来のワイヤドツトプリンタ用印字・＼ノドの
概略図である。FIG. 1 is a schematic diagram of a printing gutter for a conventional wire dot printer.

の駆動機構は。The plurality of printing wires 3 are individually fixed to the tips of corresponding armature levers 1, and the rear ends of the armature levers 1 are fixed to the armature 5. A plate spring 2 is attached to the armature 5, and the temporary spring 2 is biased by the suppressing means 4, so that the printing medium 1 is always attached to the armature 5.
It exerts a force that rotates in the direction of 0. Armature 5
The drive mechanism is.
永久磁石６、ヨーク部７、ヨーク部７の一部であるコア
部７ａ、等から成る磁気回路により構成される。It is constituted by a magnetic circuit including a permanent magnet 6, a yoke portion 7, a core portion 7a which is a part of the yoke portion 7, and the like.

ン９を介して印字媒体ＩＯ上をプラテン１１上で衝撃し
ドツトの印字を行う。When not printing, the C armature 5 resists the rotational force of the leaf spring 2.
is attracted to the permanent magnet 6, and the printing wire 1 is attracted to the printing medium 10.
and is in a non-contact state. During printing, when the coil 8 is energized to generate a magnetic flux in the magnetic circuit that cancels the magnetic flux of the permanent magnet 6, the armature 5 is released from the attractive force of the permanent magnet 6, and the printing wire 1 is rotated by the rotational force of the leaf spring 2. A dot is printed by impacting the printing medium IO on the platen 11 via the ink ribbon 9.
ところで、コイル８は、その巻初め、巻終りのリード線
がプリント基板１２の所定位置にはんだ付は固定さ九て
いる。このリード線は、巻枠本体から直接引き出されて
いるもの、良導電材からノ戊る細径ピンにからげられて
いるもの等がある。Incidentally, the lead wires of the coil 8 at the beginning and end of the winding are fixed at predetermined positions on the printed circuit board 12 by soldering. This lead wire may be drawn out directly from the main body of the winding frame, or may be tied to a small diameter pin cut out of a highly conductive material.
一般に、印字ヘッドのコイル８は印字ヘッドの小型化の
ために極力小さくすることが必要であり、また、吸引力
を高めるために巻線の巻数を多くする必要がある。この
ため１巻枠は薄くせざるを得ず、リード線の位置寸法精
度は非常に悪かった。Generally, the coil 8 of the print head needs to be made as small as possible in order to downsize the print head, and the number of turns of the winding wire needs to be increased to increase the suction force. For this reason, the first winding frame had to be made thinner, and the positional and dimensional precision of the lead wires was extremely poor.

ル組込の合理化の防げとなっていたはかりか、組込から
はんたイ」けまでに多大な作業時間を要していた。Therefore, when the coil is installed, the tip of the lead wire will be largely displaced from the predetermined solder pads on the printed circuit board 1 to J2, and the lead wire material or small diameter bottle will be placed in the predetermined position on the printed circuit board 12. Soldering requires guidance to the position, and this guidance has to be done manually, which prevents the rationalization of coil installation. It took a lot of work time.
本発明の目的は、Ｌ記の如き従来技術の欠点を解消し、
