Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明はシリアルプリンター等の印字機構の横送り方
式、特にベルト駆動方式に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a lateral feed system for a printing mechanism such as a serial printer, and more particularly to a belt drive system.
従来、この種のシリアルプリンタのキャリッジ横送り
方式は、駆動源（モータ）を１個とし、駆動源軸に固定
されたベルトプーリ及びそれに噛合されたベルトにて構
成されていた。Conventionally, the carriage lateral feed method of this type of serial printer has been configured with a single drive source (motor), a belt pulley fixed to the drive source shaft, and a belt meshed with the belt pulley.
したがって、印字機構をプラテン軸に平行に左右方向
に移動し印字を行なうと、移動方向切換時に微小に印字
位置がずれる欠点があった。つまり、駆動源の回転方向
切換時にベルトの張り側とゆるみ側が逆転することによ
り、ベルトプーリとベルト間のバックラッシ量分とベル
トの伸び変化量分が印字位置を変化させる欠点があっ
た。Therefore, when printing is performed by moving the printing mechanism in the left-right direction parallel to the platen axis, there is a drawback that the printing position is slightly shifted when switching the moving direction. That is, when the rotation direction of the drive source is changed, the tension side and the slack side of the belt are reversed, so that there is a drawback that the backlash amount between the belt pulley and the belt and the belt elongation change amount change the printing position.
本発明は、キャリッジの両サイドに駆動源を構成し、
制御することにより、高印字品質可能なキャリッジ横送

ク駆動可能なキャリッジ横送り方式を提供する。The present invention comprises drive sources on both sides of the carriage,
A carriage lateral feed method capable of high print quality by controlling, and a carriage lateral feed method capable of high torque driving by synchronously controlling a drive source are provided.
〔実施例〕 次に本発明の実施例について図面を参照して説明す

し、キャリッジ５は左方向に移動し印字する。In FIGS. 1 and 2, a carriage 5 equipped with a printing mechanism 5a slides horizontally on a front guide shaft 3 and a rear guide shaft 4 fixed to the left and right side frames 1 and 2, and a belt 6 is attached to the carriage 5. It is fixed by a fixing metal fitting 7. The belt 6 is hung between drive pulleys 9a and 9b fixed to the rotary shafts of drive source motors 8a and 8b fixed to the left and right side frames 1 and 2. In the case of printing from left to right in FIG. 3, the motor 8a is rotated in the direction of arrow A. At this time, the belt 6 rotates in the direction of arrow A, and the carriage 5 fixed to the belt moves to the right to print. On the contrary, when printing from right to left, move the motor 8b to the arrow B
Rotate in the direction. At this time, the belt 6 rotates in the direction of arrow B, and the carriage 5 moves to the left to print.

ルトの伸び変化量がキャリッジ位置つまり印字位置をず
らす原因となっていた。By rotating the drive pulley 9a in the direction A, tension side tension Ti and loose side tension Ts are generated on the belt (Ti> Ts) where there is one drive source.
9a must be rotated in the anti-A direction, and the tension side of the belt reverses the slack side, and at the time of this switching, the backlash amount between the drive pulley and the belt teeth and the belt extension change amount due to the difference in tension cause the carriage position, that is, the printing position. Was causing the shift.
本実施例では、キャリッジ移動方向に合わせて別駆動

字位置のずれをなくし高印字品質なキャリッジ横送りが
可能となる。In this embodiment, a separate drive source is used in accordance with the carriage movement direction so that the tension side and the slack side of the belt are always constant, so that the carriage position, that is, the print position is prevented from being displaced, and the carriage lateral feed with high print quality is performed. Is possible.
また、片方向印字たとえば印字動作はキャリッジが左
方向から右方向に移動時のみ行なう場合、また上記印字
位置のずれ量が許容できる場合は、モータ8a,8bを同一
方向に同期回転させることにより、高トルク駆動が可能
となる。Further, in one-way printing, for example, when printing is performed only when the carriage moves from the left to the right, and when the amount of deviation of the printing position is allowable, the motors 8a and 8b are synchronously rotated in the same direction. High torque drive becomes possible.
本発明は以上説明したように、駆動源をキャリッジの
両サイドに構成することにより、印字位置を安定させ、
高印字品質を生み出す効果がある。また上記駆動源を同
期制御することにより高トルク駆動が可能である。As described above, the present invention stabilizes the printing position by configuring the drive source on both sides of the carriage,
It has the effect of producing high print quality. Further, high torque drive is possible by synchronously controlling the drive sources.
