To the downstream side of. Subsequently, the sheet piece A is sandwiched between the conveying surfaces of the pair of endless belts 51 and 52 of the sheet piece width shifting mechanism 50, and moves with the movement of the endless belts 51 and 52.

The movement of the piece A of paper is as follows.
The sheet A is a pair of endless belts 51 of the sheet width adjusting mechanism 50,
Even if it enters between the transport surfaces of 52, the pair of endless belts 5
This is because the nipping force of 1, 52 is weaker than the nipping force of the first nipping roller 30, so that the carrying force of the first nipping roller 30 is stronger than the paper force of the sheet width aligning mechanism 50. The pair of endless belts 51, 52 cyclically move with their respective conveying surfaces on the tension side inclined along the conveying path 11 from the other side in the width direction from the upstream side to the downstream side toward the paper piece guide 24 side. Therefore, when the rear end of the paper piece A is disengaged from the first holding roller 30, the paper piece A becomes a pair of endless belts 51,
By 52, the course is changed in the circulating movement direction and the sheet is moved to the paper piece guide 24 side. When the upper front end of the paper piece A hits the paper piece guide 24, the traveling direction is bent along the guide and advances in the conveyance direction along the conveyance path 11.

At this time, even when the paper pieces A are overlapped with each other, the plurality of overlapped paper pieces A, A are brought into contact with one endless belt 51 or the other endless belt 52 which is separately driven to rotate and moved to the paper piece guide 24 side. Therefore, the advancing direction can be surely bent even with the overlapped paper pieces A, whereby the inclination of the paper pieces A can be corrected and the paper pieces A can be corrected and conveyed to a fixed position.

Further, since the rotation speeds of the drive rollers 53 and 55 on both sides, which are respectively wound around the respective endless belts 51 and 52, are different from each other, a plurality of overlapping sheet pieces A and A are respectively shifted to the sheet piece guide 24 side by time. By doing so, it is possible to correct the inclination of each paper piece A and eliminate the overlapping state. In this way, the long side of the paper piece A is aligned with the paper piece guide 24, and the paper piece A advances along the paper piece guide 24 as it is. When the front end of the paper piece A reaches the pair of second holding rollers 40, the paper piece A is sandwiched between the driving roller 42 and the driven roller 43 of the second holding roller 40, and the paper piece A is rotated with the rotation of the second holding roller 40. Move forward in the transport direction.

[0031]

According to the paper piece width-shifting mechanism and the paper piece conveying device of the present invention, the pair of endless belts that face each other with the conveying path in between have their respective conveying surfaces extending from the upstream side to the downstream side of the conveying path. Since the paper sheet is inclined toward the guide side, the inclination of the paper sheet is corrected by the endless belts that rotate from both sides along the paper sheet guide, so even if the paper sheets overlap, the inclination of each paper sheet is surely corrected. And can be conveyed in the correct posture. Therefore, it is possible to realize the automatic selection of the paper pieces A in the above-mentioned game hall and achieve labor saving.
