The conveyance force and the tapping action of the rear end portion act on the paper sheets. At this time, since a large conveying force is applied only to the trailing portion of the skewed sheet, the skew of the sheet is corrected while shifting in the direction perpendicular to the drawing.

Next, FIG. 6 shows the action of the reversing unit in the embodiment shown in FIGS. 1 to 5 when the reversing paper sheet and the reversing paper sheet try to enter the reversing unit. Shows. The guide roller 15 presses the front end 33 of the paper sheet that is about to enter the reversing portion against the conveyor belt 6 and at the same time completes the admission to the reversing portion, and the rear end 34 of the paper sheet that is about to be inverted is formed on the conveyor belt 9. Since the pressing action is also provided, even if two or more sheets are brought into the main reversing section continuously in a state of being close to each other, the reversing operation can be performed without causing any trouble such as a jam.

Next, FIG. 7 shows a modification of the embodiment shown in FIG.
Paper sheets that do not turn over, and the length in the transport direction is abnormally short.
For example, it shows a state in which the folded paper sheet 38 enters the first transport path and is transported through the gate 11.
Since such a paper sheet 38 usually causes a problem in the post-processing section, it is removed before reaching the post-processing section by a sorting means (not shown).

However, as shown in FIG. 7, by making the distance between the end point of holding by the conveyor belts 5 and 6 and the start point of holding by the conveyor belts 5 and 7 sufficiently short, the length in the conveying direction is abnormally short. Paper sheets can also be transported smoothly. It should be noted that, in the above illustrated embodiments, the method of winding the belts constituting each conveying path is not limited to the illustrated example, and the feeding direction and the length of the paper sheets are the size and size of the paper sheets to be handled. It goes without saying that the design can be changed as appropriate according to the properties.

Further, it is needless to say that the position and the number of the guide rollers 15 can be arbitrarily selected according to the properties of the paper sheets to be handled. Further, the projection 17 provided on the outer peripheral surface of the guide roller 15 is not limited to the shape as in the above-described embodiment, and is, for example, as shown in FIG.

FIG. 10 shows the state of the front end 33 of the paper sheet and the front end side end portion 33a when the paper sheet enters the space formed by the carry-in guide frame 12 and the carry-out guide frame 13. Since the outer peripheral diameter of the brush member 47 provided on the outer peripheral surface of the guide roller 45 is larger than the outer peripheral diameter when the conveyor belt 8 is wound around the pulley 27, the paper sheet is It receives a forced deformation force and is pressed against the conveyor belt 6.

The amount of deformation at this time is regulated by the carry-in guide frame 12, and the front end 23 of the paper sheet is forcibly deformed, so that the rigidity of the paper sheet is apparently increased, and the paper sheet is It smoothly advances in the guide frames 12 and 13, and finally collides with the entry stop member 14 and stops (see FIG. 11). At this time, since the distance between the outer circumference of the guide roller 45 and the entrance stop member 14 is set to be slightly longer than the length of the conveyed paper sheet in the conveying direction, the distance is also provided on the outer peripheral surface of the guide roller 45. Since the distance between the outer circumference of the brush member 47 and the entrance stop member 14 is set to be slightly shorter than the conveying direction of the conveyed paper sheet, the trailing edge 34 of the paper sheet is the outer periphery of the guide roller 45. With the rotation of the brush member 47 provided on the surface, it moves from a thick solid line to a thick two-dot chain line, and

Next, the paper sheets are clamped by the conveyor belts 8 and 9 as shown in FIG. 12, and the rear end 34 and the rear end side end portion 34a of the paper sheets are in the state shown in FIG. That is, the rear end 34 of the paper sheet receives the forced deformation force and is pressed against the conveyor belt 9. The amount of deformation at this time is regulated by the carry-out guide frame 13, and the rear end 34 of the paper sheet is forcibly deformed, so that the rigidity of the paper sheet is apparently increased, and the paper sheet is smoothed. In addition, it is possible to enter the conveyance path held by the conveyance belts 8 and 9.

After that, the sheet is conveyed along the merging guide 16 shown in FIG. 9, reaches the holding portion of the conveyor belts 9 and 5, and is conveyed downward.

Therefore, the paper sheets that are nipped by the conveyor belts 5 and 9 and are conveyed downward are conveyed as front-faced paper sheets in the same direction as the front-faced paper sheets. Further, from the gate 11 via the holding parts of the conveyor belts 5, 7 to the holding parts of the conveyor belts 5, 9 and from the gate 11 via the holding parts of the conveyor belts 6, 8.
After the reversing operation of the conveyed paper sheets, the conveyance path lengths and the conveyance speeds of the respective conveyance paths are set so that the conveyance times including the reversal time until the gripping portions of the conveyor belts 5 and 9 reach each other.

Therefore, only the paper sheets judged to be face down by the discriminating section 1 are sorted by the gate 11, the front and back sides are reversed in the above-mentioned conveying path, and when conveyed to the post-processing section by the conveyor belts 5 and 9, the front side is shown. It does not cause inconvenience in processing without causing variations in the distance from the paper sheets.
