送るようにしたものが知られているが、近時、その−間
欠勤作宛の紙葉類の送り量を自動的に２段階に切換える
ことができるようにしたいという要望がある。As this type of feeding device, for example, one is known in which a paper sheet feeding mechanism such as a sprocket or a roller is provided on a rotating shaft, and the rotating shaft is rotated intermittently to feed paper sheets a fixed amount at a time. However, recently there has been a desire to be able to automatically switch the feed rate of paper sheets addressed to intermittent workers into two stages.
本考案の目的は、このような要望をきわめて簡単な構成
のもので満足させることができる紙葉類の送り装置を提
供することにある。An object of the present invention is to provide a paper sheet feeding device that can satisfy such demands with an extremely simple configuration.
以下、本考案の一実施例を図面を参照して説明する。An embodiment of the present invention will be described below with reference to the drawings.

うにしている。A rotating shaft 1 is pivotally attached to a frame (not shown), and this rotating shaft 1
A paper sheet feeding mechanism, e.g., a roller 2, is mounted on the shaft, and a paper sheet, e.g., paper A, is held between the roller 2 and an auxiliary roll 3 disposed in close contact with the roller 2, and is fed in a certain direction. That's what I do.
前記回転軸１の一端外周部には駆動レバー４を回動自在

A one-way clutch 5 is operatively inserted between the two.
ワンウェイクラッチ５は前記駆動レバー４が送り方向（
第１図における反時計回り方向）に回動する場合にのみ
つながって該駆動レバー４の回動力を前記回転軸１に伝
達するようにしたものである。The one-way clutch 5 has the drive lever 4 in the feeding direction (
The drive lever 4 is connected only when the drive lever 4 rotates in the counterclockwise direction (in FIG. 1) to transmit the rotational force of the drive lever 4 to the rotating shaft 1.

復帰方向に回動偏倚している。Further, a lever drive mechanism, for example a cam mechanism 6, for rotating the drive lever 4 from the return side to a drive position a shown by a solid line in FIGS. 1 and 2 is provided on one end side of the drive lever 4. The drive lever 4 is rotationally biased in the return direction by a return spring 7.

。The contact portion 11 of the first stopper mechanism is disposed on the return path of the drive lever 4 and comes into contact with the drive lever 4 so as to stop the first stopper mechanism.
It is screwed onto a fixed bracket 13 fixed to the frame, so that the position can be adjusted steplessly in the direction of rotation of the drive lever 4.
一方、第２のストッパ機構の当接部１２は前記駆動レバ

で、具体的には、フレームに枢着したアーマチュア１４
の一方の回動端に螺着され、駆動レバー４の回動方向に
無段階に位置調節ができるようになっている。On the other hand, the contact portion 12 of the second stopper mechanism is located between the first return position and the drive position 3 on the return path of the drive lever.
The drive lever 4 is provided so as to be freely intervening between the
This is for regulating the second return position C by coming into contact with the armature 14, which is pivotally connected to the frame.
The drive lever 4 is screwed onto one rotating end of the drive lever 4 so that its position can be adjusted steplessly in the rotating direction of the drive lever 4.
また、前記第２のストッパ機構の当接部１２を前記駆動
レバー４の復帰路へ選択的に介在させる送り量切換え機
構１５を設けている。Further, a feed amount switching mechanism 15 is provided that selectively interposes the contact portion 12 of the second stopper mechanism in the return path of the drive lever 4.

ーマチュア１４が前記スプリング１７の偏倚力によって
時計回り方向へ回動し、前記第２のストッパ機構の当接
部１２が駆動レバー４の復帰路へ介在するようになって
いる。The feed rate switching mechanism 15 includes an electromagnet 16 disposed opposite to the other rotating end of the armature 14, and a rotation bias of the armature 14 in a direction away from the electromagnet 16 between the armature 14 and the fixed bracket 13. When the electromagnet 16 is energized, the armature 14 is attracted by the electromagnet 16 and rotates counterclockwise, causing the abutting portion 12 of the second stopper mechanism to engage the drive lever 4. When the electromagnet 16 is turned off from the return path, the armature 14 rotates clockwise due to the biasing force of the spring 17, and the abutting portion 12 of the second stopper mechanism It is interposed in the return path of the drive lever 4.
このような構成のものであれば、まず電磁石１６への通
電を断った状態でレバー駆動機構のカム板９を回転させ

第２のストッパ機構の当接部１２に当接する第２の復帰
位置Ｃとの間で往復回動動作を行う。With such a configuration, if the cam plate 9 of the lever drive mechanism is rotated with the electromagnet 16 de-energized, the drive lever 4 can be moved between the drive position a and the drive position a as shown in FIG. A reciprocating rotational movement is performed between the second return position C, where the second return position C contacts the contact portion 12 of the second stopper mechanism.
したがって、該駆動レバー４にワンウェイクラッチ５を
介して接続された回転軸１がロール２と共に比較的小角
度づつ送り方向へ間欠的に回転して用紙Ａを送る。Therefore, the rotating shaft 1 connected to the drive lever 4 via the one-way clutch 5 rotates intermittently together with the roll 2 in the feeding direction by a relatively small angle to feed the paper A.
次いで電磁石１６に通電して第２のストッパ機構の当接
部１２を第２図に示すように駆動レバー４の復帰路外へ
退避させると、前記駆動レバー４が駆動位置ａと第１の
ストッパ機構の当接部１１に当接する第１の復帰位置す
との間で往復回動動作を行うこととなる。Next, when the electromagnet 16 is energized and the contact portion 12 of the second stopper mechanism is retracted out of the return path of the drive lever 4 as shown in FIG. A reciprocating rotational movement is performed between the first return position in contact with the contact portion 11 of the mechanism.
したがって、前記回転軸１およびローラ２の間欠回転角
度が大きくなり、−間欠勤作宛の用紙Ａの送り量が増大
する。Therefore, the intermittent rotation angles of the rotating shaft 1 and the roller 2 become larger, and the amount of feed of the sheet A addressed to the -intermittent operation increases.
なお、前記駆動レバー４が第１又は第２のストッパ機構
の当接部１１，１２に当接している間は、該駆動レバー
４に取付けたカムフォロワ１０はカム板９から離れてい
る。Note that while the drive lever 4 is in contact with the contact portions 11 and 12 of the first or second stopper mechanism, the cam follower 10 attached to the drive lever 4 is separated from the cam plate 9.

バー４の可動範囲を変更するようなものに比べてはるか
に簡単な構成で用紙の送り量を２段階に切換えることが
できるものである。In this way, this feeding device is provided with two types of stopper mechanisms each having abutting portions whose positions can be adjusted independently on the return path of the drive lever, and the abutting portion 12 of one stopper mechanism is controlled by the feed amount switching mechanism 15. By selectively intervening in the return path of the drive lever 4, the rotation range of the drive lever 4 can be changed. For example, two types of lever drive mechanisms can be provided and used selectively to drive the lever. The paper feeding amount can be switched in two stages with a much simpler configuration than a system in which the movable range of the lever 4 is changed.
なお、送り機構はローラに限らず、例えばスプロケット
等であってもよい。Note that the feeding mechanism is not limited to rollers, and may be, for example, a sprocket.
また、レバー駆動機構は前記のものに限られないのは勿
論であり、例えば、電磁ソレノイドを用いたようなもの
でもよい。Further, the lever drive mechanism is of course not limited to the one described above, and may be one using an electromagnetic solenoid, for example.
また、送り量切換え機構も前記構成に限られないのは勿
論であり、要するに第２のストッパ機構の当接部を駆動
レバーの復帰路へ選択的に介在させることができるもの
であればどのような構成のものであってもよい。Furthermore, it goes without saying that the feed amount switching mechanism is not limited to the above-mentioned configuration.In short, any mechanism that can selectively interpose the contact portion of the second stopper mechanism in the return path of the drive lever may be used. It may have a similar configuration.
更に第１、第２のトツパ機構の当接部をそれぞれ独立に
位置調節可能なものにしたことにより、相互に切換えら
れる２種の用紙送り量をそれぞれ独立に調節することが
できるという便利さがある。Furthermore, by making the abutting portions of the first and second topper mechanisms independently adjustable in position, there is the convenience of being able to independently adjust the two types of paper feed amounts that can be switched between each other. .
