産業上の利用分野
この発明は、シリアルプリンタのキヤリア駆動
装置に関する。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a carrier drive device for a serial printer.
従来の技術
従来、キヤリアに一部が保持されたベルトやワ
イヤ等の条材を、左右に配置した複数のプーリに
巻回し、一方のプーリをモータに連結し他方のプ
ーリを支持部材に回転自在に支承し、モータを駆
動し条材の引張力によりキヤリアを移動させるよ
うにしたものがある。Conventional technology Conventionally, a strip material such as a belt or wire, which is partially held by a carrier, is wound around multiple pulleys arranged on the left and right, one pulley is connected to a motor, and the other pulley is used as a support member to freely rotate. There is one in which the carrier is supported by a carrier and driven by a motor to move the carrier by the tensile force of the strip.
条材が長期の使用により伸びるとキヤリアの送
り量に狂いが生ずる。これを防止するために、従
動側のプーリを支承する支持部材を移動自在に保
持し、螺子により支持部材を任意位置に固定する
従来例がある。 If the strip material stretches due to long-term use, the feed rate of the carrier will become inconsistent. In order to prevent this, there is a conventional example in which a support member supporting the driven pulley is held movably and the support member is fixed at an arbitrary position with a screw.
他の従来例として、従動側のプーリを支承する
支持部材を発条により付勢することにより条材の
弛みを防止するようにしたものがある。 Another conventional example is one in which the support member that supports the driven pulley is biased by a spring to prevent the strip from loosening.
発明が解決しようとする問題点
上述した従来例のうち、前者は条材の張力を測
定しながら螺子を締めなければならず調節作業が
面倒である。Problems to be Solved by the Invention Among the conventional examples described above, in the former, the screw must be tightened while measuring the tension of the strip, making the adjustment work troublesome.
後者はキヤリアの移動方向が変わると発条の撓
み量に変化が生じ、キヤリアの位置は往路と復路
とで差が生じ、印字位置や消字位置に狂いが生じ
る。 In the latter case, when the direction of movement of the carrier changes, the amount of deflection of the spring changes, and the position of the carrier differs between the forward and return trips, causing deviations in printing and erasing positions.
この発明はこのような点に鑑みなされたもの
で、条材の伸びに対する調節作業を容易にし、ま
た、キヤリアの位置の狂いを防止しうるシリアル
プリンタのキヤリア駆動装置をうることを目的と
する。 The present invention has been made in view of the above points, and an object of the present invention is to provide a carrier drive device for a serial printer that facilitates adjustment work for elongation of a strip and prevents the carrier from being misaligned.

付螺子１７を設ける。Means for Solving the Problems This invention involves winding a strip 7 held on a carrier 1 around pulleys 9 and 11, connecting the pulley 9 to a motor 8, supporting the pulley 11 on a support member 10, and The member 10 is displaceably attached to a frame 13, the support member 10 is biased by a spring 14, and the frame 13 is provided with a tightening screw 17 for fastening the support member 10 to an arbitrary position.
作 用
条材７が伸びた場合、締付螺子１７を緩めると
支持部材１０が変位し条材７に張力を付与する。
締付螺子１７を締めると支持部材１０が固定され

ても条材７が伸縮することがなく、キヤリア１の
位置の狂いを防止する。Operation When the strip 7 is stretched, loosening the tightening screw 17 displaces the support member 10 and applies tension to the strip 7.
When the tightening screw 17 is tightened, the support member 10 is fixed. Therefore, even if the moving direction of the carrier 1 changes, the strip 7 does not expand or contract, thereby preventing the carrier 1 from being misaligned.

る。Embodiment An embodiment of the present invention will be described based on the drawings. 1 is a carrier, and the carrier 1 holds a printing head 2 and a ribbon cassette 3. The carrier 1 is a carrier shaft 5 parallel to the platen 4.
and a guide 6 to be slidably held.
A belt 7, which is a strip member partially held by the carrier 1, is connected to a pulley 9 directly connected to a motor 8 and a support member 1.
0 and is wound around a pulley 11 supported by
The support member 10 is rotatably held by a frame 13 by a shaft 12, and is biased by a spring 14. Further, an arc-shaped elongated hole 15 whose radius is centered around the shaft 12 is formed in the support member 10, and a tightening screw 17 is provided which is inserted into the elongated hole 15 and screwed into the projection piece 16 of the frame 13. ing.

く、操作も極めて容易である。 In such a configuration, when the tightening screw 17 is loosened, the support member 10 is rotated by the force of the spring 14, and the belt 7 is balanced with the force of the spring 14.
Apply just the right amount of tension. When the tightening screw 17 is tightened and the support member 10 is fixed, even if the motor 8 is rotated in both forward and reverse directions to reciprocate the carrier 1, the support member 10 will not rotate and the belt 7 will not expand or contract. Therefore, as long as the number of steps for driving the motor 8 is determined and the carrier 1 is moved, the position of the carrier 1 will not change depending on the difference between the outward and return trips. The operation for applying tension to the belt 7 is extremely easy, as it is only necessary to loosen and retighten the tightening screw 17.
