環状体を突設したものである。It is an object of the present invention to provide an automatic paper feeder capable of correcting the deflection of a document during feeding. The position is regulated by a guide plate, and the feed roller and reversing roller work together to separate and feed the documents to be sent one by one.A pair of thin annular bodies is attached to either the reversing roller or the paper feeding roller. It is a projecting structure.
以下、本発明の一実施例を図面に基づいて詳細に説明す

原稿案内板２ａ。FIG. 1 is a schematic plan view of an automatic paper feeder according to an embodiment of the present invention, FIG. 2 is an enlarged sectional view of the mou 5' in FIG. 1, and FIG. It is a sectional view taken along B-i. In FIGS. 1 to 3, reference numeral 1 denotes a document loading table, 2a and 2b document guide plates, and 03a and 3b document guide plates 2a.

ム７ａ 、７ｂが設けられている。6 is a reversing roller, 8 is a rotating shaft of the reversing roller 6,
The reversing roller 6 and the rotating shaft 8 are slidably connected to each other by a bearing 12. Note that the reverse rotation roller 6 and the paper feed roller 4 are pressed against each other. 9a and 9b are friction plates provided on both sides of the reversing roller 6 on the rotating shaft 8, and bearings 13a and 1 provided inside.
3b is a coil spring 011 which is slidably connected to the rotating shaft 8, and 010a and 10b which press the friction plate 9b in the direction of the arrow X in FIG. 2 are stop members.
, sb, are fixed to the rotating shaft q on both sides with a reversing roller 6 and a coil spring 11 interposed therebetween. A pair of thin annular rubbers 7a and 7b are provided on the circumferential surface of the zero reversing roller 6, which has high friction members attached to both sides of the friction plates sa+sb.
次に１以上の構成を有する自動給紙装置の動作を説明す
る。Next, the operation of an automatic paper feeder having one or more configurations will be explained.
まず、摩擦板ｓａ 、ｅｂおよびコイルばね１１はトル
クリミッタを構成している。すなわち、このトルクリミ
ッタの働きにより逆転ローラ６にかかる負荷が小さい場
合は、回転軸８が第２図矢線Ｘ方向に回転すると逆転ロ
ーラ６も矢線Ｅ方向に回転し逆転する。これに対し、逆
転ローラ６にかかる負荷が大きい場合は、回転軸８が矢
線Ｘ方向に回転しても、逆転ローラ６は矢線Ｅ方向には
回転しない。したがって、給紙ローラ４と逆転ローラ６
との間に送信原稿が存在しないか、あるいは１枚の送信
原稿のみが介在しているときは、逆転ローラ６が矢線Ｆ
方向に回転し、また給紙ローラ４と逆転ローラ６との間
に送信原稿が複数枚介在しているときは、逆転ローラ６
が矢線Ｘ方向に回転するようにトルクリミッタの限界を
設定すれば、複数枚の送信原稿を１枚づつ分別して給紙
することができる。なお、停止部材１０ｂを第３図矢線
Ｃ方向あるいは逆方向に移動させて固定することにより
、トルクリミッタの限界を調整設定できる。First, the friction plates sa and eb and the coil spring 11 constitute a torque limiter. That is, when the load applied to the reversing roller 6 is small due to the action of this torque limiter, when the rotary shaft 8 rotates in the direction of the arrow X in FIG. 2, the reversing roller 6 also rotates in the direction of the arrow E and reverses. On the other hand, when the load applied to the reversing roller 6 is large, the reversing roller 6 does not rotate in the arrow E direction even if the rotating shaft 8 rotates in the arrow X direction. Therefore, the paper feed roller 4 and the reversing roller 6
If there is no original to be transmitted or only one original to be transmitted is present between the reverse roller 6 and the
direction, and when there are multiple documents to be sent between the paper feed roller 4 and the reversing roller 6, the reversing roller 6
By setting the limit of the torque limiter so that the document rotates in the direction of the arrow X, it is possible to separate and feed a plurality of documents to be sent one by one. The limit of the torque limiter can be adjusted by moving and fixing the stop member 10b in the direction of the arrow C in FIG. 3 or in the opposite direction.
次に、送信原稿の偏向矯正動作を第４図を用いて説明す
る。。第４図は本発明の動作説明図である。Next, the operation of correcting the deflection of a transmitted document will be explained with reference to FIG. . FIG. 4 is an explanatory diagram of the operation of the present invention.
第４図において、１４は送信原稿であり、１６ａ。In FIG. 4, 14 is a transmission document, and 16a.
１５ｂは給送ローラ４と逆転ローラ６上の環状ゴム７ａ
、７ｂとの接触点を示している。なお、第４図も第１図
と同じ部材には同一符号を付している。15b is an annular rubber 7a on the feeding roller 4 and the reversing roller 6.
, 7b. The same members in FIG. 4 as in FIG. 1 are designated by the same reference numerals.
まず、送信原稿１４は給紙方向（矢線Ｈ）において第４
図のように偏向する。このとき、送信原稿１４の案内板
２ｂ側には、原稿１４のたわみ部１４ａが発生する。そ

、ごくわずかな時間経過後に、原稿１４の端部は接触点
１５ａにおいて、給送ローラ４と環状ゴム７ａに、も挾
持される。First, the transmission document 14 is placed in the fourth position in the paper feeding direction (arrow H).
Deflect as shown. At this time, a bent portion 14a of the original document 14 is generated on the guide plate 2b side of the original document 14 to be transmitted. At the first instant, the edge of the original 14 is held between the feeding roller 4 and the annular rubber 7b at the contact point 15b, and after a very short time, the edge of the original 14 is held at the contact point 15a. It is also held between the feeding roller 4 and the annular rubber 7a.
ところで、原稿１４の端部が接触点１５ｂにおいて挾持

わずかではあるが時間がかかり、その間は原稿１４が接
触点１６ｂにおいてのみ挾持されることになる。すなわ

４ａには、元の状態に戻ろうとする復元力が常に働いて
いる。したがって、原稿１４が接触点１５ｂにおいての
み挾持されているときに、原稿１４は接触点１ｓｂを中
心にして第４図矢線Ｃ方向に瞬時に回転し、原稿１４の
端部が接触点１５ａに当接して、その回転は停止するか
ら、原稿の偏向は矯正できる。By the way, it takes a very short amount of time from when the edge of the original 14 is clamped at the contact point 15b to when it is clamped at the contact point 15a, and during that time, the original 14 is clamped only at the contact point 16b. . That is, the document 14 has a degree of freedom in rotation about the contact point 16. Furthermore, the bent portion 1 of the original 14
There is always a restoring force working in 4a that tries to return to its original state. Therefore, when the original 14 is held only at the contact point 15b, the original 14 instantly rotates in the direction of the arrow C in FIG. When they come into contact, their rotation stops, so the deflection of the document can be corrected.

ーラを下に配しても良い。In the above detailed description of the present invention, the material of the annular body provided at a distance on the circumferential surface of the reversing row 26 is rubber, but this is not limited to an elastic body such as rubber, but may also be made of aluminum or the like. It may be a rigid body, but according to experiments, 0
The ring was perfect. Further, the annular body may be provided on the feeding roller side instead of the reversing roller, but experiments have shown that it is preferable to provide the annular body on the reversing roller side. Further, the vertical positional relationship between the feeding roller and the reversing roller is irrelevant to the present invention, and the reversing roller may be placed above and the feeding roller may be placed below.
