上られることになる。Next, each component of the print head will be explained in more detail with reference to FIGS. 2 and 3. A drive coil 8 for driving the printing wire 5 is inserted into a plurality of printing yoke 7.
a and a yoke member that integrally has a notched long hole 7b for wiring the coil 8 provided on both sides of the magnetic pole yoke into which the coil 8 is inserted, and 9σ is sandwiched between the printed wiring board 6 and the print head yoke member 7. an insulating rubber plate that insulates the two, 1
For tilted printing, insert the coil 8 into the Rad Yoke member 7 and connect it to the printed circuit board, and at the same time, insert and fix the print head yoke member 7 into the print head base 1, and at the same time, connect the print head base 1 and the print head yoke member 7. a yoke set screw for fixing the printed wiring board 6 in a state where it is held between the two;
1, a protruding wall 7C provided on the periphery of the print head yoke member 7;
The armature guide 12 fitted into the armature guide 11 is an armature whose one end is rotatable about the guide pin 111L of the armature guide 11. This armature 12 turns the signal current to the coil 8 on and off Accordingly, the armature is rotated in a direction approaching the yoke 71L against the armature torsion spring 13, and the printing wire 6 crimped to the end of the armature 12 is pushed out and moved to the outside of the tip of the nozzle 3 to print. It is supposed to be done. 14
There is an armature stopper 15 (4, which is a stopper for the cover 2).For example, there is a 6x7 dot matrix for printing, and in this case, the printing wire 6, armature 12, drive coil 8
etc., 36 wires 5 and related members are each strung up.

数だけ行なえばコイルの配線作業は完了する。The present embodiment has the above configuration, and the wiring at the end of the winding of the drive coil 8 is connected to the notch of the yoke member 7 provided near the insertion position of the coil 8. After inserting it into the long hole Ab, insert it into the hole 6b of the printed wiring board 6 and insert the copper foil 6C.
All you have to do is solder and connect the wires, and the coil wiring work is completed by doing the same work for the number of dots.
したがって、コイル8の配線が短く出来るとともに、巻
線挿入孔6bを順番に埋めていくことで配線ミスをする

リンタ一本体間の電気的結合もワンタッチで行なえる。Therefore, the wiring of the coil 8 can be shortened, and by sequentially filling the winding insertion holes 6b, there is no possibility of wiring mistakes, and the reliability is high against wire breakage and the like. In addition, since the printed wiring board 6 connector protrusion 6a is integrally formed, simply inserting it into the printer 16 of the printer body (not shown) will allow the connection between the head and the printer body. Electrical connections can also be made with one touch.
以上のように本発明によれば簡単な構成で配線作業性が
優れ、信頼性が高い印字ヘッドが得られる。As described above, according to the present invention, a printing head with a simple configuration, excellent wiring workability, and high reliability can be obtained.
