つた。[Problems to be Solved by the Invention] In the above method, positioning is performed by bringing the edge of the paper into contact with a positioning plate. At this time, if the paper is bent, accurate positioning will not be possible. Therefore, in the case of very thin paper, sagging is likely to occur, making it difficult to adjust the width.
また、この方法では、幅寄せの方向が一定で同
一の機械で反対側への幅寄せを行なうことは不可

The present invention provides a pair of conveyance means, such as a pair of rollers or a pair of belts, which grip and convey paper, spaced apart in the width direction of the paper, and makes it possible to adjust the feed speed of both conveyance means. The paper is tilted by making the feeding speed of the means larger than the feeding speed of the other conveying means, and then,
On the other hand, the paper is characterized in that the width of the paper is adjusted by making the feed speed of the conveying means on one side smaller than the feed speed of the conveying means on the other side.

The speed of the pair of conveyance means provided apart in the width direction of the paper can be adjusted independently, so when the paper is ready to be conveyed by the conveyance means, the conveyance speed of one of the conveyance means is first adjusted. is made relatively larger than the conveying speed of the other conveying means. This causes the paper to be tilted.
At the stage where this inclination has occurred by a predetermined amount, the conveying speed of one conveying means is made relatively smaller than the conveying speed of the other conveying means, contrary to the previous method. As a result, the forced inclination of the paper returns to its original state, but along with this operation, the width of the paper can be adjusted.

行うことができる。 Depending on which side of the pair of conveyance means is made to have a higher conveyance speed than the other, the width of the paper can be shifted to the left or right. In addition, the width adjustment amount can also be adjusted freely. Of course, the inclination itself can also be controlled freely.
以下、本発明の実施例を図面によつて説明す

５図は、装置を上方から見たもので、左側および
右側従動ローラ２，４は用紙５に隠れている。 In FIG. 1, 1 is a left-hand drive roller, 2 is a left-hand driven roller that is in contact with this left-hand drive roller 1,
3 is a right side drive roller, 4 is a right side driven roller that is in contact with the right side drive roller 3, and the paper is transferred to the left and right side drive rollers 1, 3 and driven rollers 2, 4, respectively.
It is held and transported. Said left drive roller 1
The and right drive rollers 3 can be driven at different speeds. 2 to 5 are views of the apparatus from above, and the left and right driven rollers 2, 4 are hidden behind the paper 5.

連の動作により、用紙５の幅寄せを行なう。 The left drive roller 1 and the right drive roller 3 are initially driven at the same speed and convey the sheet 5, which enters from below in FIG. 2, without causing any inclination (FIG. 2). Subsequently, in a second stage, the right-hand drive roller 3 is driven at a higher speed than the left-hand drive roller 1. As a result, the portion of the paper 5 that is in contact with the right drive roller 3 is conveyed more than the portion that is in contact with the left drive roller 1, so that the paper 5 is tilted counterclockwise as shown in FIG. Then the third
As a step, the left drive roller 1 and the left drive roller 3 are driven at the same speed. Then, paper 5 becomes
It is sent while maintaining the inclination created in the second stage (Figure 4). At this stage, the width of the paper 5 is adjusted to each roller. Subsequently, in the fourth stage, contrary to the second stage, the speed of the left drive roller 1 is set higher than the speed of the right drive roller 3, and the paper 5 is given clockwise rotation. As a result, the paper 5 no longer has any inclination, and as a result, the paper 5 is shifted to the right side (FIG. 5). In the next step, the left drive roller 1 and the right drive roller 3 are driven at the same speed to send out the paper 5. Through this series of operations, the width of the paper 5 is adjusted.

FIG. 6 shows the moving positions of the two parts superimposed on each other.
In FIG. 6, paper 5 is →→→→
Take the position in the order of →.
また、第７図に示すように、左側駆動ローラ１

Ａとする。このＡ点の軌跡は第８図の曲線Ｂに示
すようになり幅寄せ量αの幅寄せが行なわれるこ
とがわかる。 In addition, as shown in FIG. 7, the left drive roller 1
Let A be the projection point of the paper 5 which is the midpoint between the right drive roller 3 and the right drive roller 3. The locus of this point A becomes as shown by curve B in FIG. 8, and it can be seen that the width adjustment is performed by the width adjustment amount α.
ローラの送り速度に差がある場合に、用紙が傾
くのは次の理由による。今、用紙５を固定して、
ローラおよびＡ点が動くと考えると、第９図にお
いて、Δtの時間に、左側駆動ローラ１の送り量
をｌ、右側駆動ローラ３の送り量をｌ＋Δlとす
る。両者の速度差はΔl／Δtである。 The reason why the paper is tilted when there is a difference in the feeding speed of the rollers is as follows. Now fix paper 5,
Considering that the roller and point A move, in FIG. 9, at time Δt, the feed amount of the left drive roller 1 is assumed to be l, and the feed amount of the right drive roller 3 is assumed to be l+Δl. The speed difference between the two is Δl/Δt.
ｌ＝（ｒ−ｄ）・θ
ｌ＋Δl＝（ｒ＋ｄ）・θ
これより、θ＝Δl／（２・ｄ）が得られ、時
間Δtの間に角度θだけ傾くことになる。 l=(rd)·θ l+Δl=(r+d)·θ From this, θ=Δl/(2·d) is obtained, and it will be tilted by the angle θ during the time Δt.
上記の動作のうち、第２段階と第４段階をひき
つづいで行なうと、用紙５に傾きを与え、傾きを
もどす動作中にも用紙５を搬送することになるの
で、第３段階を省略することができる。 Of the above operations, if the second and fourth steps are performed successively, the paper 5 will be tilted and the paper 5 will be conveyed even during the operation to restore the tilt, so the third step may be omitted. Can be done.
また、第２段階と第４段階の各ローラの速度の
大きさを選ぶことにより用紙５に傾きを残したま
ま幅寄せを終了することが可能である。これを用
いて、進入してくる用紙５の傾きを知ることがで
きると、傾きの補正にも用いることができる。 Further, by selecting the speed of each roller in the second stage and the fourth stage, it is possible to finish the width adjustment while leaving the inclination of the paper 5. If this can be used to determine the inclination of the incoming sheet 5, it can also be used to correct the inclination.
なお、本実施例においては、左側駆動ローラ１
と右側駆動ローラ３を同軸に配置しているが、同
軸でなくても各動作は同様に行なうことができ
る。 Note that in this embodiment, the left drive roller 1
Although the right drive roller 3 and the drive roller 3 are arranged coaxially, each operation can be performed in the same way even if they are not coaxially arranged.
さらに、幅寄せ量を大きくとることが必要な場
合は、同様のローラ対を多段に配置するか、ルー
プを用いて同一機構に用紙５を繰返し通すように
すればよい。 Furthermore, if it is necessary to increase the width shifting amount, the same roller pairs may be arranged in multiple stages, or the paper 5 may be repeatedly passed through the same mechanism using a loop.
また、搬送手段としてローラの代わりに、ベル
ト等を用いても同じ効果が得られる。そして従動
側を無くしてすべて駆動側としてもよい。装置の
大形化を許すとすれば、反時計回りの傾きを形成

別に構成することもできる。 Further, the same effect can be obtained by using a belt or the like instead of a roller as the conveyance means. Also, the driven side may be eliminated and all the driving side may be used. If it is possible to increase the size of the device, the mechanism for forming a counterclockwise inclination and the mechanism for forming a clockwise inclination may be constructed separately.
