A movable roller is provided at the terminal end of the conveying means, and moves downward by two degrees with respect to the conveying roller depending on the thickness of the paper sheet discharged from the conveying means, and a fulcrum is provided at one end of a crank that pivotally supports this movable roller. is provided with an enlarging mechanism part that rotates around a fulcrum depending on the thickness of the paper sheets to enlarge the width of the movable roller; , and the other end is pivotally supported by the other end of the crank.The enlarging mechanism guides the paper sheets discharged from the conveyance path to the stacking section, and the paper sheets accumulated in the stacking section. A swingable movable guide body that presses the surface in the plane direction is provided.

(Function) In other words, the present invention has a two-dimensional configuration, so that the paper sheet passes between the transport roller as a reference and the movable roller, so that the movable roller corresponds to the thickness of the paper sheet. The value increases through the expansion mechanism, and the increase value is expanded through the expansion mechanism.
By raising the tip of the movable guide body, paper sheets discharged from the transport path can be guided to the stacking section, and the paper sheets can be moved between the transport roller and the movable roller by passing between the transport roller and the movable roller. is lowered, and the paper sheets carried in can be pressed into the stacking section by the restoring force of the movable guide body.

(Example) The present invention will be described below based on an example shown in FIGS. 1 and 2. In Figure 1, (赳) is a banknote (
(Ila), (Ila), (
llb) is a drive roller (12a) that rotates at the same speed.
Conveyor belts 1-1 (13) which are wound around L (12b) and which sandwich and convey banknotes (P) are conveyor belts (ll
a), is a stacking section with an open top for horizontally stacking binary banknotes (P) discharged from the conveying end of (Ilb). On the opening side of this stacking section (13), an L-shaped movable guide body (14), which will be described later, is rotatably supported and guides banknotes (P) discharged into the stacking section (13). At the same time, the stacked banknotes (P) are pressed into contact with the stacking part (13).

That is, the movable guide body (14) is attached to a support shaft (15) that supports the rear part of the L-shape, and is located near the support shaft (15), and rotates around the support shaft (15). A movable shaft (16) for vertically moving the rear part of the movable guide body (14), and a coil spring (one end of which is stretched on the opposite side of the dual movable shaft (16) with respect to the support shaft (15). 17).

) rotates clockwise around the support shaft (15) as a fulcrum by the restoring force of the coil spring (17). therefore,
The banknotes (P) that have entered the stacking section (13) are pressed into the stacking section (13) by the movable guide body (14) and can be stacked. In addition, since the movable guide body (14) can be rotated via the enlarging mechanism (Dan) having a crank (19), even when a thick banknote (P) is sent, the It is possible to move the movable guide body (14) upwards proportionately.

〔Effect of the invention〕

As explained above, according to the present invention, the guide body is not pushed up by the stiffness of paper sheets as in the past,
By passing the paper sheet between a constantly rotating drive roller and a movable roller, the thickness of the paper sheet is expanded through the expansion mechanism, which pushes up the movable guide body. Regardless of the stiffness of the paper sheets, the movable guide body can be pushed up to smoothly guide and accumulate the paper sheets.

Therefore, the paper sheets will not be deformed while the movable guide body is being pushed up due to the stiffness of the paper sheets, or paper jams will not occur due to the movable guide body not being pushed down.
This has the effect that it can be accumulated in the accumulation section.
