本発明はプリンタ機構、特に高速印字装置に使用する印
字機構部の一部を構成する活字ベルトとバックアップフ
レームで構成されるプリンタ機構に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a printer mechanism, and more particularly to a printer mechanism comprised of a type belt and a backup frame forming a part of a printing mechanism used in a high-speed printing device.
従来のプリンタ機構は活字文字の配列方向に沿って走行

レームで構成され、バックアップフレームの活字ベルト
走行面は面一になりていた。A conventional printer mechanism consists of a type belt that runs along the direction in which the type characters are arranged, and a backup frame that guides the type belt, and the type belt running surface of the backup frame is flush with the surface of the type belt.

がありた。また活字ベルト上昇による印字不良を調整工
事で行う為に多大の工数を資す欠点かありた。In the past, wear and tear accidents occurred because the type belt ran in full contact with the belt running surface of the backup frame.During printing, the type belt rises, so the type character surface and the printing surface are flush with each other. There were printing function defects such as uneven development, missing printed characters, and uneven characters. Another drawback was that it required a large amount of man-hours to correct printing defects caused by the rise of the type belt.

リンタ機構を提供することにある。The printer mechanism according to the present invention can improve printing quality by suppressing the rise of the type belt and stabilizing its running. Furthermore, by using steps on the belt running surface to reduce the number of contact parts, it is an object of the present invention to provide a printer mechanism which prevents breakage of the type belt and enables high-quality printing.

構はバックアップフレームのベルト走行面上に突き当て
部と段差を設けて構成される。The printer mechanism of the present invention is composed of a type belt running along the arrangement direction of the type character faces and a backup frame having a belt running surface. That is, the printer mechanism of the present invention is constructed by providing an abutting portion and a step on the belt running surface of the backup frame.

ぞろなどの事故がなくなシ印字品位機能が向上した。In the printer mechanism of the present invention, an abutting portion is provided on the belt running surface of the backup frame to prevent the type belt from rising during printing, so that the surface collision between the type surface and the print hammer surface coincides. There are no more accidents such as missing print or uneven print, and the print quality has been improved.
さらにまたベルト走行面に段差を設けた事によって活字
ベルトの接触部分が少なくなシ折損などの事故がなくな
シ耐用時間が向上した。Furthermore, by providing a step on the belt running surface, there are fewer contact parts of the type belt, which eliminates accidents such as breakage and improves the service life.

致する様にした。When printing is performed, a current flows through the coil 1, which causes the core 2 to become magnetic, and the actuator lever 3 is attracted in the attraction direction a by the action of the magnetic force. The attracted actuator lever 3 moves the tail cap 4 in the operating direction, so that the print hammer 9 in the hammer guide 6 flies and prints the type formed on the type belt 10 via the print paper 7 and the ink ribbon 8. It collides with the character surface 11 and prints. Thereafter, the print hammer 9 returns to its original position due to the tension of the spring 5. As shown in FIG. 2, the type belt 10 is attached to a drive pulley 15 and an idler pulley 16, and the driving force of the motor 17 is transmitted to the drive pulley 15 so that the type belt 10 runs in a running direction C. Conventional printer mechanism, 4th
As shown in the figure, since the belt running surface 13 of the backup frame 12 is flush, there is a tendency for the type belt 10 to rise during printing, resulting in misalignment of the surface collision between the type character surface 11 and the print hammer 9 surface. However, as shown in FIG. 3, by providing an abutment part 14 in the backup frame 12 according to the present invention, the type belt 11 is prevented from rising and the surface collision between the type character surface 11 and the print hammer 9 surface is made to coincide. .
又段差１８を設けることにより活字ベルト１０の接触部
分を少なくし摩耗などによる折損事故の要因を除去した
。Further, by providing the step 18, the number of contact parts of the type belt 10 is reduced, thereby eliminating the cause of breakage accidents due to wear and the like.
以上説明した様に本発明によシ印字品質機能の向上なら
びに活字ベルトの折損交換がなくなり手直し工数の低減
に効果がある。As explained above, the present invention is effective in improving the printing quality function and eliminating the need to replace broken type belts, thereby reducing the number of man-hours for rework.
本発明のプリンタ機構はいったんバックアップフレーム
中のベルト走行面に活字ベルトをセットすれば上昇が防
止され印字品位のバラツキが生じない効果がある。The printer mechanism of the present invention has the effect that once the type belt is set on the belt running surface in the backup frame, it is prevented from rising and variations in print quality do not occur.
