【考案の詳細な説明】 産業上の利用分野 この考案は、プリンタに使用される長尺紙巻取装置に関

長尺状の紙を巻取る巻取装置を備えたプリンタにおい
て、その巻取装置として第２図に示すようなものが存す
る。すなわち、相対向するフレーム１にＵ字形の切欠２
が形成され、これらの切欠２に支軸２の両端が保持され
ている。この支軸３にはモータ（図示せず）に連結され
たギヤ３０と座金３１と巻取軸３２とが回転自在に嵌合
され、さらに、座金３１と巻取軸３２の端面との間に圧
縮スプリング３３が介装され、支軸３の両端付近に形成
された環状の溝４には止め輪５が止着されている。ま
た、図示しないが、座金３１と巻取軸３２とは一体的に
回転するように両者の嵌合部分に互いに係合する突部と
凹部とが形成されているものである。2. Description of the Related Art For example, in a printer including a winding device for winding a long paper such as a journal paper used for a cash register, there is a winding device as shown in FIG. That is, the U-shaped notches 2 are formed in the frame 1 facing each other.
Both ends of the support shaft 2 are held in these notches 2. A gear 30 connected to a motor (not shown), a washer 31, and a take-up shaft 32 are rotatably fitted on the support shaft 3, and further, between the washer 31 and the end face of the take-up shaft 32. A compression spring 33 is interposed, and retaining rings 5 are fixed to annular grooves 4 formed near both ends of the support shaft 3. Further, although not shown, the washer 31 and the take-up shaft 32 are formed with a projection and a recess that engage with each other at their fitting portions so as to rotate integrally.
したがつて、長尺状の紙を端部から巻取軸３２に巻回
し、ギヤ３０を継続的に回転させると、圧縮スプリング
３３の力により座金３１がギヤ３０の側面に圧接されて
いるため、座金３１と巻取軸３２とは摩擦力により追従
回転する。したがつて、他の紙送り装置（図示せず）に
より巻取軸３２の方向へ送られた紙は順次巻取軸３２に
巻取られる。他の紙送り装置による紙送り動作が停止す

たがつて、巻取軸３２上の紙の巻回径の変化の拘らず、
送つた分だけの紙を巻取軸３２により巻取り、紙が弛む
ことを防止する。Therefore, when a long paper is wound around the take-up shaft 32 from the end and the gear 30 is continuously rotated, the washer 31 is pressed against the side surface of the gear 30 by the force of the compression spring 33. The washer 31 and the winding shaft 32 follow and rotate due to frictional force. Therefore, the paper fed in the direction of the take-up shaft 32 by another paper feeding device (not shown) is successively taken up by the take-up shaft 32. When the paper feeding operation by another paper feeding device is stopped, the washer 31 and the winding shaft 32 are stopped, but the gear 30
Keeps rotating while slipping on washer 31. Therefore, regardless of the change in the winding diameter of the paper on the winding shaft 32,
The amount of the fed paper is wound by the winding shaft 32 to prevent the paper from loosening.
考案が解決しようとする問題点 しかし、止め輪４は鋼板により形成されて熱処理も施さ
れているため硬度が高く、また、常に圧縮スプリング３
３の力によりスラスト荷重を受けているため支軸３の溝
４が摩耗し幅が広くなる。このため、巻取軸３２が軸方
向に動き巻取る紙の直進性が損なわれ、また、圧縮スプ
リング３３の力が低下するためギヤ３０から座金３１へ

る。さらに、回転力を伝達するためにギヤ３０と巻取軸
３２との間に座金３１と圧縮スプリング３３とを介装す
るため、部品点数が増加する等の問題がある。However, since the retaining ring 4 is made of a steel plate and is also heat-treated, the retaining ring 4 has a high hardness and is constantly compressed.
Since the thrust load is applied by the force of 3, the groove 4 of the support shaft 3 is worn and the width becomes wide. Therefore, the straightness of the paper wound around the take-up shaft 32 in the axial direction is impaired, and the force of the compression spring 33 is reduced, so that the rotation transmission torque from the gear 30 to the washer 31 is also reduced. The taking action becomes unstable. Further, since the washer 31 and the compression spring 33 are interposed between the gear 30 and the winding shaft 32 to transmit the rotational force, there are problems such as an increase in the number of parts.

たスプリングとよりなるものである。Means for Solving Problems A take-up shaft having a boss having a predetermined diameter formed at one end so as to wind an end portion of a long paper on the outer periphery, and one end having the same diameter as the boss of the take-up shaft A drive wheel having a boss formed therein and connected to a motor, and a support shaft held by the frame and concentrically holding the winding shaft and the drive wheel opposite to the boss. And a hook that is engaged with either one of the drive wheel or the winding shaft, and a plurality of stoppers that are fixed to the support shaft and come into contact with the end surfaces of the winding shaft and the drive wheel. Is provided at one end and both ends are formed of springs wound around the bosses of the drive wheel body and the winding shaft with a predetermined tightening force.

であるため、その効率がきわめて高いものである。Therefore, the rotation of the drive wheel in only one direction is transmitted to the take-up shaft by the spring, but since the rotation is transmitted by the force in the torsion direction of the spring, the drive wheel and the take-up shaft are rotated in the thrust direction. The load does not act and wear of the stopper-supporting portion of the stopper is prevented, improving durability. Further, since the torsion torque of the spring is stable, the rotation torque transmitted from the drive wheel to the winding shaft becomes constant. Furthermore, since only one spring needs to be provided as a rotation transmission member between the drive wheel and the take-up shaft, the number of parts can be reduced, and the power transmission from the drive wheel to the take-up shaft is direct. Therefore, its efficiency is extremely high.

された小孔１５に係合されている。Embodiment An embodiment of the present invention will be described with reference to FIG. Since the supporting structure of the support shaft 3 is as described in FIG. 2, the same reference numerals are used and the description thereof is omitted. A gear 6, which is a drive wheel made of synthetic resin, and a winding shaft 7 are rotatably fitted to the support shaft 3, and a gear is provided in an annular groove 4 formed near both ends of the support shaft 3. A stop ring 5, which is a stopper, is fixed to the end surfaces of the winding shaft 6 and the winding shaft 7. And
The take-up shaft 7 is provided with a groove 8 for inserting an end portion of a long paper to be taken up, and a flange 9 for aligning side edges of the paper, and a boss 10 is provided on an outer surface of the flange 9. A peripheral wall 11 is formed on the axis of the support shaft 3, and a boss 12 is integrally formed on the side surface of the gear 6. Both ends of a spring 13 are wound around the bosses 10 and 12 in a slightly tensioned state. A hook 14 formed at one end of the spring 13 is engaged with a small hole 15 formed in the peripheral wall 11.

り、紙が弛むことを防止する。In such a configuration, when a long sheet of paper is inserted into the groove 8 of the winding shaft 7 from the end and the gear 6 is continuously rotated according to the winding direction of the spring 13, the boss 12 and the spring The spring 13 rotates due to the friction with the inner circumference of 13, and the winding shaft 7 rotates due to the engagement between the hook 14 and the small hole 15. Therefore, the paper fed in the direction of the take-up shaft 7 by another paper feeding device (not shown) is sequentially taken up by the take-up shaft 7. When the paper feeding operation by another paper feeding device is stopped,
Although the winding shaft 7 and the spring 13 stop, the gear 6 continues to rotate while slipping the boss 12 with respect to the spring 13. Therefore, irrespective of the change in the winding diameter of the paper on the take-up shaft 7, the fed paper is taken up by the take-up shaft 7 to prevent the paper from loosening.

が可能となる。In this way, the rotation of the gear 6 in only one direction causes the spring 1 to rotate.
3 is transmitted to the winding shaft 7, but rotation is transmitted by the force of the spring 13 in the twisting direction, so that the gear 6 and the winding shaft 7 are transmitted.
The load in the thrust direction does not act on the groove, and the groove 4 is not worn by the retaining ring 5 to widen the width.
The durability can be improved. Also, spring 1
Since the torsion torque of 3 is stable, the rotation torque transmitted from the gear 6 to the winding shaft 7 is constant. Further, since only one spring 13 needs to be provided as the rotation transmitting member between the gear 6 and the winding shaft 7, the number of parts can be reduced.

効果を有する。Effect of the Invention Since the invention is configured as described above, the rotation of the drive wheel in only one direction is transmitted to the winding shaft by the spring.
Since rotation is transmitted by the force in the torsion direction of the spring,
The load in the thrust direction does not act on the drive wheel and the take-up shaft, so that the wear of the fastening portion between the stopper and the support shaft can be prevented and the durability can be improved.
Since the torsional torque of the spring is stable, the rotation torque transmitted from the drive wheel to the winding shaft can be made constant, and one spring is used as a rotation transmission member between the drive wheel and the winding shaft. Since it is only necessary to provide only one, the number of parts can be reduced, and since the power transmission from the drive wheel to the winding shaft is direct, the efficiency is extremely high.
