【考案の詳細な説明】
本考案はマグネツトコイルによりアーマチユア
を吸引又は解放して印字ワイヤを駆動する印字ワ
イヤ駆動装置に関し、特に前記アーマチユアを板
ばねで支持する印字ワイヤ駆動装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a printing wire driving device that drives a printing wire by attracting or releasing an armature using a magnetic coil, and more particularly to a printing wire driving device that supports the armature with a leaf spring.

イヤ１を前方に駆動する。 FIG. 1 shows an example of a conventional printing wire drive device as described above, which is of a so-called release drive type. In the figure, 1 is a printing wire, 2 is an armature to which the printing wire 1 is fixed, 3 is a leaf spring that supports the armature 2, 4 is a permanent magnet,
5 is a core around which a coil 6 is wound, and 7 and 8 are yokes. In the non-printing state, the armature 2 is attracted to the core 5 by the magnetic force of the permanent magnet 4, and the leaf spring 3 is bent in the opposite direction to the driving direction. During printing, the magnetic field of the permanent magnet 4 is canceled out by energizing the coil 6, and the leaf spring 3
The restoring force releases the armature 2 and drives the printing wire 1 forward.
印字ワイヤ１が第２図に示すようにプラテン９
と衝突すると、アーマチユア２の印字ワイヤ取付
け端と反対側の端部は慣性により矢印Ａ方向に運
動し、板ばね３を第３図に示すように撓ませる。
その結果印字ワイヤ１の復帰が遅くなり、第４図
に示すインパクト時間t1が長くなる。これは印字
速度の高速化を妨げ、又インクリボンの寿命を早
めると共に印字のぼけを生ずる原因となる。 The printing wire 1 is connected to the platen 9 as shown in FIG.
When the armature 2 collides with the print wire, the end of the armature 2 opposite to the print wire attachment end moves in the direction of arrow A due to inertia, causing the leaf spring 3 to deflect as shown in FIG.
As a result, the return of the printing wire 1 is delayed, and the impact time t 1 shown in FIG. 4 becomes longer. This prevents the printing speed from increasing, shortens the life of the ink ribbon, and causes blurring of the print.
そこで本考案は上記のような印字ワイヤ駆動装
置において、インパクト後の印字ワイヤの戻りを
早めんとするもので、以下図面に従つて本考案を
説明する。 Therefore, the present invention is to speed up the return of the printing wire after impact in the above-mentioned printing wire drive device.The invention will be described below with reference to the drawings.
第５図は本考案の一実施例を示すもので、第１
図と同一の構成要素については同一の番号を付し
ている。 FIG. 5 shows one embodiment of the present invention.
Components that are the same as those in the figures are given the same numbers.
１０はアーマチユア支持用の板ばね３の前に並
置した補助板ばねで、インパクト時に前記板ばね
３がこの補助板ばね１０に当接する。したがつて
板ばね３は補助板ばね１０の全面で衝撃を緩和さ
れながら当接し、インパクト時のアーマチユア２
の慣性にかかわらず、第３図に示すような板ばね
３の撓みの量が減少しその分だけ印字ワイヤ１の
戻りが早くなる。 Reference numeral 10 denotes an auxiliary leaf spring arranged in front of the armature supporting leaf spring 3, and the leaf spring 3 abuts against this auxiliary leaf spring 10 at the time of impact. Therefore, the leaf spring 3 contacts the auxiliary leaf spring 10 with the entire surface of the auxiliary leaf spring 10 absorbing the impact, and the armature 2 at the time of impact.
Regardless of the inertia of the print wire 1, the amount of deflection of the leaf spring 3 as shown in FIG. 3 is reduced, and the return of the printing wire 1 is accelerated accordingly.
以上のようにして本考案では、印字ワイヤを取
り付けたアーマチユアを板ばねで支持する印字ワ
イヤ駆動装置の高速駆動化を可能とし、インクリ
ボンの長寿命化と印字品位の向上が図れるもので
ある。 As described above, the present invention enables high-speed driving of the printing wire drive device in which the armature to which the printing wire is attached is supported by a leaf spring, thereby extending the life of the ink ribbon and improving the printing quality.
