りを防止するようにしたものである。 In many cases, paper is fed out one by one from a stack of paper as needed. In this case, there are various devices that prevent double sheet feeding and feed out sheets one by one, but this invention uses a drive shaft to rotate one of a set of rollers that feed out the sheets. The other rollers utilize the elasticity of the coil to prevent double sheet feeding.

なるように調節機構で調節される。 The roller 1 is rotated in the direction of the arrow by a drive mechanism (not shown), approaches the paper 3, and feeds the paper 3 to the right in FIG. The table 2 is adjusted by an adjustment mechanism so that the top of the paper 3 is at a constant height as the paper 3 is fed out.

ローラ１による用紙３の繰り出しには、用紙３
を一枚ずつ繰り出すような機構はついていない。 The paper 3 is fed out by the roller 1.
There is no mechanism to feed out the sheets one by one.

転する。 The drive shaft 4 is rotated by a drive mechanism (not shown), and rotates a first roller 5 connected to the drive shaft 4. The drive shaft 4 and the drive mechanism are connected by, for example, an electromagnetic clutch, so that when the electromagnetic clutch is disengaged, the first roller 5 can rotate freely. The stand 8 rotatably holds the driven shaft 6, and is provided with elasticity by attaching, for example, a leaf spring. Since a drive device is not connected to the driven shaft 6, the driven shaft 6
The second roller 7 connected to the first roller 5 and the second roller 7 is rotated by the movement of the paper 3 that enters between the first roller 5 and the second roller 7.

成する。 1 are rollers that pull out the paper 3 that has passed between the first roller 5 and the second roller 7, and when the paper 3 reaches the rollers 9 and 10, the first
The rotation of the drive shaft 4 of the roller 5 is stopped.

次に、第１図の第２のローラ７部分の組立断面
図を第２図に示す。第２図の１１は凹部、１２は
滑り台、１３はノツチ、１４はノツチ板、１５は
固定板、１６はコイルである。 Next, FIG. 2 shows an assembled sectional view of the second roller 7 portion shown in FIG. 1. In FIG. 2, 11 is a recess, 12 is a slide, 13 is a notch, 14 is a notch plate, 15 is a fixing plate, and 16 is a coil.

凹部１１をもつ滑り台１２は台８に固定され
る。 A slide 12 having a recess 11 is fixed to the platform 8.

次に、第２図の凹部１１と滑り台１２の一例を
第３図に示す。 Next, FIG. 3 shows an example of the recess 11 and slide 12 shown in FIG. 2.

付けるとともに滑り台１２の面を移動するノツチ
１３をもつ。コイル１６は一端をノツチ板１４に
固定し、他端を従動軸６と連結する固定板１５に
固定する。 The notch plate 14 is rotatably attached to the driven shaft 6 and has a notch 13 that moves on the surface of the slide 12. The coil 16 has one end fixed to the notch plate 14 and the other end fixed to a fixed plate 15 connected to the driven shaft 6.

ツチ１３が滑り台１２の面に沿つて移動し、凹部
１１に入る。さらに第２のローラ７を回転する
と、ノツチ１３は凹部１１から出て移動する。 Therefore, when the second roller 7 is rotated, the notch 13 moves along the surface of the slide 12 and enters the recess 11. When the second roller 7 is further rotated, the notch 13 moves out of the recess 11.

第２図はノツチ１３が滑り台１２の面にあり、
凹部１１に入つていない状態を示したものであ
る。 In Figure 2, the notch 13 is on the surface of the slide 12,
This figure shows a state in which it has not entered the recess 11.

これに対し、第４図は第２のローラ７を回転
し、ノツチ１３が凹部１１に入つてつている状態
を示したものである。 On the other hand, FIG. 4 shows a state in which the second roller 7 is rotated and the notch 13 has entered the recess 11.

ノツチ１３が凹部１１に入つた状態で第２のロ
ーラ７への回転力がなくなると、蓄えられたコイ
ル１６の弾性で第２のローラ７に加えた回転と反
対方向に第２のローラ７を回転する。 When the rotational force on the second roller 7 disappears with the notch 13 in the recess 11, the stored elasticity of the coil 16 causes the second roller 7 to move in the opposite direction to the rotation applied to the second roller 7. Rotate.

用紙３がローラ１によつて一枚だけ第１のロー

ローラ５によつて繰り出されるので、結局用紙３
はローラ９，１０側に繰り出されていく。 When only one sheet of paper 3 is placed between the first roller 5 and the second roller 7 by the roller 1, the sheet 3 is fed out toward the rollers 9 and 10 by the rotational force of the first roller 5. In this case, the second roller 7 is rotated by the paper 3, and the notch 13 moves on the surface of the slide 12 and enters the recess 11, but the force that suppresses the rotation of the second roller 7 is weak, so the notch 13 It comes out of the recess 11 and moves. Therefore, elasticity is not stored in the coil 16. Therefore, since the paper 3 is fed out by the first roller 5, the paper 3 ends up being fed out by the first roller 5.
is fed out to the rollers 9 and 10 side.

た第２のローラ７側の用紙３は繰り出し前の位置
に戻される。 On the other hand, when two sheets of paper 3 are overlapped by the roller 1 and enter between the first roller 5 and the second roller 7,
The paper 3 on the first roller 5 side is fed out by the rotational force of the first roller 5. However, the paper 3 on the second roller 7 side enters between the first roller 5 and the second roller 7 due to the elasticity of the platform 8, but the notch 13
When the second roller 7 enters the recess 11, the rotation of the second roller 7 is suppressed by the coil 16 unless the notch 13 comes out of the recess 11, so that the second roller 7 stops moving. 1st
When the paper 3 on the roller 5 side reaches the rollers 9 and 10 and the rotation of the drive shaft 4 of the first roller 5 is stopped,
Since the first roller 5 can rotate freely, the coil 1
6 rotates the second roller 7 in the opposite direction to the feeding direction. As a result, the paper 3 on the second roller 7 side, which had stopped moving, is returned to the position before being fed out.

台８には弾性をもたせているので、用紙３の厚
さが変つても、同じような作用で用紙３を一枚ず
つ繰り出すことができる。 Since the table 8 has elasticity, even if the thickness of the paper 3 changes, the paper 3 can be fed out one by one with the same action.

つ繰り出すことができる。(c) Effects of the Invention According to the present invention, even if the thickness of the paper varies, the paper on the first roller 5 side is fed out, and the paper on the second roller 7 side is returned to the position before feeding. It is possible to prevent two sheets of paper from being fed and feed the sheets one by one.
