図機）等に良く使われている。Conventional structure and its problems Conveyance mechanisms using a pair of rollers that sandwich and convey sheet materials such as paper are used in office automation equipment such as printers, copying machines, and facsimile machines, as well as plotters in CAD systems (automatic drawing machines). It is often used for etc.
この機構の一般的な構成は、搬送するシート部材の幅に
合わせて主ローラがあり、これにいわゆる補助ローラを
押圧させである。The general structure of this mechanism is that there is a main roller corresponding to the width of the sheet member to be conveyed, and a so-called auxiliary roller is pressed against this main roller.

ている。The auxiliary rollers 2, 2' are rotatably mounted on an arm 6 via a shaft 6, and the arm 6 is also swingably attached to a block 8 via a shaft 7. 9 is a slide shaft of the block 8, along which the block 8 can move in the axial direction of the main roller 1. Reference numeral 10 denotes a brake seat, which is pressed against the slide il+ 9 by a retaining screw 11, and generates a friction f'I load for the movement of the block 8.
ブレーキシュー１ｏを、スライド軸９に常に押し付けた
構成にしであるのは、プロッターの作図精度を確保する
ため、紙を押圧作図時に、補助ローラ２のスライド方向
への位置ずれを防止するためである。The reason why the brake shoe 1o is always pressed against the slide shaft 9 is to ensure the plotting accuracy of the plotter and to prevent the auxiliary roller 2 from shifting in the sliding direction when printing by pressing the paper. .
アーム６とブロック７は、軸７の後方で引張りバネ１２

同時に作用する構成になっている。The arm 6 and the block 7 are connected to a tension spring 12 behind the shaft 7.
It is connected by . Reference numeral 13 indicates an adjustment screw, and reference numeral 14 indicates an eccentric cam, which is located at the rear of the block 8 and is configured to simultaneously act on the auxiliary rollers 2 and 2'.
補助ローラ２，２′の動きを、第２図で説明する。The movement of the auxiliary rollers 2, 2' will be explained with reference to FIG.
紙をはさんでいる時は、偏心カム１４が実線の位置にあ

により補助ロー２２，２′ は、主ローラ１に押圧され
ている。When the paper is being sandwiched, the eccentric cam 14 is at the position indicated by the solid line, separated from the adjusting screw 13, and the auxiliary rows 22, 2' are pressed against the main roller 1 by the action of the tension spring 12.
紙をはさまず、補助ローラ２を移動させる時は、図示し

。When moving the auxiliary roller 2 without sandwiching the paper, a motor (not shown) rotates the eccentric cam 14 to the position shown by the dashed line and pushes the adjustment screw to float the auxiliary roller 22.degree. 2'.
この時、補助ローラ２のユニットは、移動可能となる。At this time, the unit of the auxiliary roller 2 becomes movable.

いので、移動時の位置決めが正確に行いにくい。This movement is performed manually by pushing the unit part by hand. At this time, in the conventional mechanism, the brake shoe 10 is pressed against the slide shaft, so this frictional load is large and a great deal of force is required to move it. In addition, since the friction load during movement is large, it is difficult to position accurately during movement.

明を省略する。FIG. 3 is an overall configuration diagram of an embodiment of the present invention, and FIG. 4 is an explanatory diagram of the same operation. In FIG. 3, 1 to 14 are the first
Since it is the same as that shown in FIG. 2, the same number is given and the explanation is omitted.

離を定めている。A brake shoe 16 is pressed against the slide shaft 9 by two compression springs 16. Numeral 17 is a cover for the compression spring 16, and numeral 18 is a slide bin with one end fixed to the cover 17. There are four slide bins that can be slid through the holes in the block 8, and the sliding distance is determined by a stopper 19 attached to the tip. .
以下、動作を説明する。固定の補助ローラ２′は、従来
例と同じ動作なので、説明は省略する。The operation will be explained below. The fixed auxiliary roller 2' operates in the same manner as in the conventional example, so a description thereof will be omitted.
紙を押圧する時は、偏心カム１４は、実線の位置にあり
、調節ネジ１３が接触しておらず、従来７へ−１
例と同様に、アーム６が引張り・バネ１２に引かれ、補
助ローラ２は主ローラ１に押圧される。When pressing the paper, the eccentric cam 14 is in the position indicated by the solid line, the adjustment screw 13 is not in contact with it, and the arm 6 is pulled by the tension spring 12 as in the conventional example 7-1. The roller 2 is pressed against the main roller 1.
一方、カバー１７は、偏心カム１４に押され、圧縮バネ
１６を圧縮した状態になり、この圧縮バネ１６の力でブ
レーキシュー１６がスライド軸９に押圧される。このた
め、紙押正時の補助ロー２２のスライド軸方向への位置
ずれは防止できる。On the other hand, the cover 17 is pushed by the eccentric cam 14, compressing the compression spring 16, and the brake shoe 16 is pressed against the slide shaft 9 by the force of the compression spring 16. Therefore, displacement of the auxiliary row 22 in the direction of the slide axis during paper pressing can be prevented.

ネ１６が開放されてブレーキシュー１６を押圧する力が
非常に小さくなる。When the paper is not being pressed, the eccentric cam 14 is rotated by a motor (not shown) so that it comes to the position shown by the dashed line, the adjustment screw 13 is pushed, and the auxiliary roller at the tip of the arm 6 floats. On the other hand, the force bar 17 is also pushed by the compression spring 16 until the stopper 19 hits the block 8 and comes to the position indicated by the chain line, and is not pushed by the eccentric cam 14, so the compression spring 16 is released and presses the brake shoe 16. force becomes very small.
その結果ブレーキシュー１６によるスライド軸９への押
圧力が、非常に小さく、そしてブレーキシューの摩擦負
荷も非常に小さくなシ、手動で補助ローラの移動を、小
さい力で軽く行うことができる。移動時の補助ローラ２
の位置決めも、簡単にできる。As a result, the pressing force on the slide shaft 9 by the brake shoe 16 is very small, and the friction load on the brake shoe is also very small, making it possible to manually move the auxiliary roller lightly with a small force. Auxiliary roller 2 during movement
Positioning can also be done easily.
発明の効果
以上、述べた様に本発明では、従来、紙の抑圧、非押圧
にかかわらず、ブレーキシューをスライド軸に押圧して
いたのを、紙の非押圧時は、ブレーキシューのスライド
軸への押圧を解除する構成にしたことで、補助ローラの
移動が非常に小さい力で軽く行えるようになり、また移
動時の位置決めも簡単にでき、操作性を大幅に改善する
ことができる。Effects of the Invention As stated above, in the present invention, the brake shoe is pressed against the slide shaft of the brake shoe when the paper is not pressed, whereas in the past, the brake shoe is pressed against the slide shaft regardless of whether the paper is pressed or not. By releasing the pressure on the auxiliary roller, the auxiliary roller can be moved easily with very little force, and positioning during movement can be easily performed, greatly improving operability.
更に、補助ローラの押圧、非押圧の切換え、ブレーキシ
ューの抑圧、非押圧の切換えを各々、同一の偏心カムで
同時に行う様にしたので、全体の構成を従来に比べて複
雑にすることなく簡単にすることができる。In addition, the same eccentric cam is used to press the auxiliary roller, switch to non-pressing, suppress the brake shoe, and switch to non-press at the same time, making the overall configuration simpler and simpler than before. It can be done.
以上、プロッターの例で説明したが、異なる幅の紙を使
用する装置の搬送機構にも適用でき、また補助ローラ１
個だけ移動させる例で説明したが、複数の補助ローラを
移動させる装置の搬送機構にも適用できることは言うま
でもない。The above explanation is based on the example of a plotter, but it can also be applied to the conveyance mechanism of a device that uses paper of different widths, and the auxiliary roller 1
Although the explanation has been given using an example in which only one auxiliary roller is moved, it goes without saying that the present invention can also be applied to a conveyance mechanism of a device that moves a plurality of auxiliary rollers.
