本発明はドツトマトリックス状に文字や記号を構成して
印字するドツトインパクト形マトリックスプリンタに関
する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a dot impact matrix printer that prints characters and symbols arranged in a dot matrix.
従来、この種の印字ハンマ駆動装置の磁気回路では同一
穴径のコイルを使用している九め、所費轡数に対するコ

に、印字ハンマの応答周波数が低下した艶、コイルの発
熱が大きくなるという欠点を有していた。Conventionally, the magnetic circuit of this type of printing hammer drive device uses coils with the same hole diameter. Since the magnetic flux does not change rapidly when it is excited, it has the drawbacks of a decreased response frequency of the printing hammer and increased heat generation of the coil.

る。Figure 1 shows a conventionally proposed printing hammer drive wheel at, in which a permanent magnet l is sandwiched between a yoke 2.3,
A coil spool 6 is attached to the yoke 5 that corresponds to the printing hammer 4.
is inserted, and a coil 7 for releasing the printing hammer 4 is wound around it. The printing hammer 4 is a type of cantilever leaf spring, and a printing wire 8 for printing dots is attached to the free end of the leaf spring, and the other end is fixed to the yoke 3.

ンマ４の吸引力は低下しない。Normally, the printing hammer 4 is bent and attracted to the yoke 5 by the permanent magnet 1O1 and the attractive force as shown by the real edge in FIG. 1(b), but it is not necessary! At this time, when current is applied to the coil 7 to erase the permanent magnet 1) 41, the printing hammer 4 is released from the yoke surface, and the secondary strain energy stored in itself is converted to kinetic energy, resulting in b
) K ,a Moves and prints as shown in II. Although Figure 1 shows a magnetic circuit using permanent magnets, this may be replaced with an electromagnet, however,
In this case, the printing hammer is attracted by the electromagnet tm, and the printing hammer is released by cutting off the current in the coil. In such a printing hammer drive device, the first
As shown in Figures (a) and (b), the leakage magnetic flux 11 from the yoke 5 increases as it goes from the root 9 to the tip 10 of the yoke 5, so the cross-sectional area of the yoke 5 increases from the root 9 to the tip 1.
The attraction force of the printing hammer 4 does not decrease even if the magnetic flux is reduced by the amount corresponding to the leakage magnetic flux.

くする磁気回路を提供するものである。However, in the conventional printing machine drive device as shown in Figure I1, the cross-sectional area of the yoke 5 is made to be the same as the cross-sectional area of the base 9 at the tip 101. The diameter must also be the same -IIC over the entire length, so the resistance of the coil 7 increases with respect to the required number of turns, and the response frequency of the printing hammer 4 decreases because the magnetic flux does not change suddenly when the coil is 7'kmal. The disadvantage is that the coil generates more heat, which makes it impossible to print at high speed.The present invention has a tapered coil! The present invention provides a magnetic circuit that can print at high speed by winding the coil and reduce the heat generated by the coil.
次に本発明について図面を参照して詳細に説明する。Next, the present invention will be explained in detail with reference to the drawings.
第２図は本発明の一実施例を示したもので、永久磁石１

。FIG. 2 shows an embodiment of the present invention, in which a permanent magnet 1
2 is sandwiched between the yokes 13 and 14, and the printing hammer 15
A coil spool 17, which is tapered like the yoke 16, is inserted into the friend yoke 16, and a coil 18 is wound around its rotation.
ヨーク１６は根元１９から先端２０に行くに従ってヨー

積を小さくし第２図に示すように先細履にしても印字ハ
／７１５の吸引力は低下しない。The leakage magnetic flux 21 from the yoke 16 increases as it goes from the root 19 to the tip 20.
Even if the cross-sectional area is reduced by an amount commensurate with the leakage magnetic flux from 9 to the tip by 20K, and the tapered shoe is made as shown in FIG. 2, the attractive force of the printing C/715 does not decrease.
従って１本実施例のような先細１１０コイル【使用する

られる。Therefore, a tapered 110 coil as in this embodiment [one length for the required number of turns of the thick and thin coil to be used is shortened to 1!
Since the resistance of the coil can be reduced, the magnetic flux changes rapidly when excited, resulting in a magnetic circuit in which the response frequency of the printing hammer is high and the coil generates little heat.
さらに、第３図は別の実施例を示すものでヨーク１６の
形状を片テーパー状にしたものである。Furthermore, FIG. 3 shows another embodiment in which the shape of the yoke 16 is tapered on one side.
このようにしても第２図に示した実施例と同様の効果が

旨によるものであることは明白である。It is safe to assume that the same effect as the embodiment shown in FIG. 2 can be obtained even with this method! i. It is clear that this is also in accordance with the gist of the present invention.

でも同様な効果が得られることは明らかである。In FIGS. 2 and 3, the cross-sectional shape of the yoke 16 is shown as a t-square, but it is clear that similar effects can be obtained with a yoke having a circular or other cross-sectional shape.
