The transport path length and the transport speed of each transport path are set so that the transport time to reach the rear roller 12 becomes equal.

Next, the transport operation of this embodiment will be described.

The paper sheets are nipped by the conveyor belts 1 and 2 and conveyed from the arrow 27 to the gate 21. Here, in the case of face-up paper sheets, the gate 21 is rotated clockwise about the axis of the roller 10 by a drive source (not shown) to a position indicated by a chain double-dashed line in FIG. Therefore, the face-up paper sheets are conveyed to the merging guide 5 by sandwiching the conveying belts 1 and 3,
It can be pinched by the conveyor belts 1 and 4 and can be conveyed downward (in the direction of arrow 28) and conveyed, for example, in the direction of a sheet storage unit (not shown).

Next, in the case of paper sheets facing down, the gate 21 is rotated counterclockwise by the drive source (not shown) to the position shown by the solid line in FIG. Therefore, the back-faced paper sheets 29 are separated from the front-faced paper sheets by the gate 21, and as shown in FIG.
The sheet is conveyed along with the sheet, and is conveyed to the reversing unit for reversing the paper sheet by the interaction of the carry-in guide frame 22, the entry stop member 24, the carry-out guide frame 23, and the guide roller 25. Here, 29a indicates the front end face of the face-down paper sheet 29.

In the reversing unit, the paper sheet is reversed by the following operation. This reversing operation will be described with reference to FIGS.

Since the outer peripheral diameter of the protrusion 26 provided on the outer peripheral surface of the guide roller 25 is larger than the outer peripheral diameter of the pulley 19, the face-down paper sheets 29 are subjected to the forced deforming force, It is pressed against the conveyor belt 2. The amount of deformation at this time is regulated by the carry-in guide frame 22, and the front end surface 29 of the face-down paper sheet 29 is also controlled.
Since a is forcibly deformed, the rigidity of the back-faced paper sheet 29 is apparently increased, and the back-faced paper sheet 29 smoothly moves in the space formed by the carry-in guide frame 22 and the carry-out guide frame 23. Proceed to. At this time, the front end surface 29a of the face-down paper sheet 29 advances while coming into contact with the carry-out guide frame 23 as shown in FIG. The abutting portion strongly abuts the carry-out guide frame 23. As shown in FIG. 2, this portion is recessed by the notch structure portion 23c and the stepped structure portions 23a and 23b, so that it smoothly collides with the entry stop member 24 and stops.

Next, as shown in FIG. 4 and FIG.
Is configured such that the outer diameter of the protrusion 26 provided on the outer peripheral surface of the guide roller 25 is larger than the outer diameter of the pulley 19, so that the face-down paper sheet 29 is the outer peripheral surface of the guide roller 25. Along with the rotation of the protrusion 26 provided on the sheet, it is pressed against the holding roller 30 and the reversing guide 20. That is, if the folded paper sheet 29 has a fold 29c, that portion is
As shown in Fig. 5 and Fig. 5, it receives a forced deformation force. The amount of deformation at this time is regulated by the reverse guide 20 and the carry-out guide frame 23,
Further, since the rear end surface 29b of the back-faced paper sheet 29 is forcibly deformed, the rigidity of the back-faced paper sheet 29 is apparently increased, and the back-folded paper sheet 29 has a fold 29c. Smoothly enters the sandwiching roller pair 19,30.

At this time, the folded-back portion 29c at the rear end of the face-down paper sheet 29,
The rear end surface 29b and the like abut on the carry-in guide frame 22 and the carry-out guide frame 23, but a part of the carry-out guide frame 23 has stepped structure portions 23a, 23b
Since the recessed portion exists like the cutout structure portion 23c and the cutout structure portion 23c, the contact resistance with the rear end surface 29b of the face-down paper sheet 29 is reduced, so that the reversing operation can be smoothly performed. In addition,
Since the space portion surrounded by the indentation-free portion 23a of the carry-out guide frame 23 and the carry-in guide frame 22 is configured to be narrow, the paper sheets do not stay during the reversing operation, and the smooth reversing guide 20, It is possible to enter the third conveyance path constituted by the merging guide 5. After that, it is conveyed along the holding belts 1 and 4 shown in FIG. 1, and is conveyed downward along the arrow 28.

Therefore, the paper sheets that are nipped by the conveyor belts 1 and 4 and that are conveyed downward are conveyed in the same direction as that of the front-faced paper sheets. Also, from the gate 21, transfer belts 1,3
Conveyance time from the nip of the conveyor belt to the nip of the conveyor belts 1 and 4, and the gate 21 to convey the conveyor belt 1 and the roller 19
The length and speed of each transport path are set so that the transport time including the reversal time until the transport belts 1 and 4 reach the sandwiching part after the reversing operation of the transport sheets via the sandwiching part of Is set. Therefore, only the face-down paper sheets should be gate 21
And then reverse the front and back in the above-mentioned transport path, transport belt 1,
