置において、従来一般には、プッシャローラの一回転毎
に１枚の紙葉類が繰り出されるようになっている。Conventionally, multiple sheets of paper are held in a polymerized state, and a pusher roller is rotated in pressure contact with one surface along the thickness direction of the paper sheets to push out the paper sheets one by one. 2. Description of the Related Art There is known a paper sheet feeding device for feeding out a single sheet, which is pulled out by a picker roller and sent out to a predetermined conveyance path by a feed roller. Conventionally, in such a sheet feeding device, one sheet is fed out for each rotation of the pusher roller.

た場合には重合繰り出しや連鎖繰り出し等の不具合が生
じ易い。In conventional devices that require one revolution of the pusher roller to feed out one sheet, the feeding speed is limited by the rotational speed of the pusher roller. Therefore, in order to increase the feeding speed, it is necessary to increase the rotational speed of the pusher roller. However, when the rotational speed of the pusher roller is increased, problems such as polymerization and chain feeding tend to occur.
本発明はこのような事情に鑑みてなされたもので、プッ

るようにして上記の目的を達成するものである。In the sheet order feeding mechanism of the present invention, the pusher roller that pushes out the paper sheets from the holding part has a pair of friction surfaces on the outer peripheral surface facing parts, and the picker roller that pulls out the pushed paper sheets has the outer peripheral surface facing parts. The above object is achieved by having a pair of friction surfaces and rotating in synchronization with the pusher roller so that two sheets of paper can be fed out each time the pusher roller rotates.
以下、本発明の一実施例を図面を参照して説明する。 Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

ラ８の一回転毎に２枚の紙葉類１が押し出される。A pusher roller 8 is provided at a position facing the opening 3 of the front plate 4, and the pusher roller 8 is rotated in one direction by an arrow 9 by a shaft 9. A pair of paper pushing friction surfaces 10a110b made of rubber or the like are provided at opposing positions on the outer peripheral surface of the pusher roller 8, that is, at positions 180 degrees apart. As a result, when the pusher roller rotates 8 times, each friction surface 10aS10b is located on the front plate 4 side of the paper sheet 1 in the holding mechanism 2.
are pushed out sequentially. In other words, two sheets of paper 1 are pushed out each time the pusher roller 8 rotates.

。A picker roller 11 for pulling out the paper sheets 1 is provided on the paper sheet pushing side of the pusher roller 90. The picker roller 11 is configured to rotate in the same direction and synchronously with the pusher roller 9 by a shaft 12, and has a pair of friction surfaces 13a and 13b made of rubber or the like on the outer circumferential surface facing each other. is provided. As a result, two sheets of paper are pulled out for each rotation of the picker roller 11.

回転する。A one-way roller l4 is provided on the paper sheet neck drawer side of the picker roller 11 to prevent overlapping bows from being pulled out. The one-way roller 14 is arranged adjacent to the surface of the picker roller 11 at an interval required for pulling out one sheet 1, and is rotated by a shaft 15 in a direction opposite to that of the picker roller 11 (in the direction of arrow B).
これにより、引き出されるべき紙葉類１ａの剥離が容易
に行われ、１枚ずつ確実に引き出される。Thereby, the paper sheets 1a to be drawn out are easily peeled off, and each sheet is reliably drawn out one by one.

搬送路方向（矢印Ｃ方向）に送り出す。A feed roller 16 is provided on the feeding side of the picker roller 11.
The feed roller 16 is supported by a shaft 17, rotates in pressure contact with the picker roller 11, and sends out the paper sheet 1 in the direction of a predetermined conveyance path (in the direction of arrow C).

し出され、以後同様にして送り出される。According to such a configuration, since the pusher roller 8 and the picker roller l1 rotate in the same direction and at the same rotational speed, the first paper sheet 1a that is in pressure contact with the front plate 4 is rotated by one of the pusher rollers 8. It is pushed downward in the figure by two friction surfaces 10a, and is pulled out by one FIJ surface l3a of picker roller 11. At this time, the second and subsequent paper sheets 1 are held by the one-way roller 15,
Paper sheets 1a are reliably peeled off one by one. Then, the pulled out paper sheet 1a is sent out to the conveyance path side by the feed roller 16. When the pusher roller 8 rotates by 180 degrees, the second paper sheet 1 is pushed out by another friction surface 10b, and thereafter is sent out in the same manner.

送り等の不具合も生じない。According to the above embodiment, two sheets of paper 1 are reliably peeled off and fed out each rotation of the pusher roller 8 and the picker roller 11, and even if the roller speed is the same as before, the paper sheets 1 are fed out at twice the speed. It can act. Moreover, problems such as polymerization feeding and chain feeding do not occur.
