A pulley 9 for stretching 0 is provided, and the belt 8 and the belt 10 form a conveyance path 2.

The operation of this embodiment constructed as described above is
This will be described below. Paper sheet 1 conveyed in the conveyance path 2
As shown in FIGS. 1 and 2, when passing through the end of the conveying path 2, the brush roller 4 is urged upward in the drawing, and is ejected into the storage portion 5 while being deformed into a slightly wavy shape. Since it is sandwiched by the belt 8 and the belt 10, the rigidity in the axis 3 direction is high, the brush of the brush roller 4 is deformed more, and the sheet 1 is not deformed to the extent that the guide member 6 interferes. After being ejected from the transport path 2, the paper sheet 1
The rear end is scraped off and accumulated in the storage section 5. As described above, when a paper sheet jam occurs on the upstream side of the conveyance path 2 and the jammed paper sheet is removed, the storage unit 5
There is no problem if the accumulated paper sheet 11 inside is not full,
If the accumulated paper sheet 11 in the storage unit 5 is full, the accumulated paper sheet 1
When the conveying path 2 is driven in the reverse direction when the rear end of the sheet 1 is in contact with the brush roller 4, the brush roller 4 also rotates in the reverse direction, so that the uppermost sheet of the accumulated paper sheet 11 in the storage unit 5 is rotated. The leaves are scraped by the brush roller 4 from the rear end.
However, in this case, unlike the case of stacking, the paper sheet 1 is not sandwiched by the belt 8 and the belt 10, so that the rigidity in the axis 3 direction is low, and the rigidity in the axis 3 direction is almost non-existent. The roller 4 is hardly deformed, and the paper sheet is shown in FIG.
It is greatly deformed, as indicated by 11 '.

That is, the paper sheet 11 'is scraped up between the belt 10 and the brush roller 4 while being largely deformed into a wave shape, whereby the rear end of the paper sheet 11' is inside the opening of the guide member 6 described above. Even if the brush roller 4 enters the conveyance path 2 and is not scraped up further and the brush roller 4 continues to rotate in the reverse direction, the brush roller 4 is not erroneously conveyed in the reverse direction. The shape of the paper sheet 11 'in this state is as shown in FIG. According to the above-described embodiment, the paper sheet 1 is fed at the end of the transport path 2 into the storage section 5 by the solid line 1 in FIG.

Since they are conveyed respectively, there is an effect that the sheets are smoothly accumulated and the sheets are not erroneously conveyed to the conveyance path 2 even when the conveyance path 2 is rotated in the reverse direction. Needless to say, each surface of the above-mentioned guide member 6 is finished in a smooth state in which the sheet 1 is not caught. Next, another embodiment of the present invention will be described.

FIG. 4 is a side view of the paper sheet stacking apparatus of the second embodiment of the present invention, and FIG. 5 is a view in the direction of arrow B in FIG.
In both figures, the symbols 1 to 5 and 7 to 10 indicate the same components as shown in FIGS. 1 to 3. The feature of this embodiment lies in the guide member 6 shown in the first implementation section.
Instead of the center of rotation of the brush roller 4, the storage section 5 side
(On the right in the figure), overlap with the brush roller 4,
The point is that the inclined guide member 12 is arranged on the storage section 5 side. As shown in FIG. 5, the four guide members 12 are provided between the pulley 7 and the brush roller 4. The guide members 12 are not provided on both sides of the central pulley 7 and the pulley 9 in order not to extremely weaken the action of scraping the trailing end of the paper sheet ejected from the transport path 2. is there. In addition, the above-mentioned guide member 12
Are arranged such that the upper end thereof slightly overlaps the lower surface of the belt 10 forming the transport path 2. The operation of this embodiment configured as described above will be described below. The stacking operation of the paper sheet 1 transported in the transport path 2 into the storage portion 5 is exactly the same as in the above-described embodiment,
A detailed description thereof will be omitted, and only the operation when the transport path 2 is rotated in the reverse direction will be described. Needless to say, the guide member 12 described above does not cause any trouble in this case.

As shown in FIG. 4, the accumulated paper sheet 1 in the storage section 5
When the conveyance path 2 is rotated in the reverse direction while the rear end of the sheet 4 is in contact with the brush roller 4, the uppermost sheet 14 ′ of the accumulated sheet 14 is scraped up by the brush roller 4 from the rear end. Be done. However, at this time, the trailing end of the paper sheet 14 'is prevented from being conveyed by the inclined lower surface of the guide member 12 and the overlapping portion of the belt 10, and the brush roller 4 continues to rotate in the reverse direction without being scraped any further. Also, transport path 2
It cannot be mistakenly conveyed back inside. According to the present embodiment, as in the above-described embodiments, paper sheets are smoothly accumulated, and even when the transport path 2 is rotated in the reverse direction, the paper sheets may be erroneously transported to the transport path 2. It has the effect of disappearing. In addition, each surface of the above-mentioned guide member 12 is a paper sheet 1.
Needless to say, it has been finished in a smooth state that does not get caught. Further, it goes without saying that each of the above-mentioned embodiments shows an example of the present invention, and the present invention should not be limited to these.
