It consists of a path stop member 6 that enables reversal feeding with the rear end as the leading edge, and an endless belt 7 that changes the path of the sheet to be reversed. An identification means 8 for determining the position and a driving means 9 for advancing and retracting the path stopping member 6 based on the identification result are attached.

The first belt 1 has an inlet path 10 for paper sheets, an outgoing path 11 up to the path stop member 6, and following this outgoing path 11, it reaches the entrance (merging point 12) of the outgoing belts 5, 5. It forms the conveyance path 13,
Specifically, pulleys 14, 15, 16, 17, 1
8 and 19 in an endless manner, and among these, the pulleys 15 and 16 are wound on the second belt 2 and the fourth belt 4. The forward path 11 and the conveyance path 13 constitute a forward conveyance path in the present invention, and the carry-in/out belts 5, 5 constitute a carry-out path in the present invention.

The second belt 2 is wound endlessly around pulleys 20, 21, 22, and 23 in addition to the pulley 15, and the second belt 2 is wound around the third belt 3 at the pulley 20.

This third belt 3 is wound around the above-mentioned pulley 20 and a pulley 24 located between this pulley 20 and the above-mentioned pulley 16, and its upper surface constitutes a return path 25 for reversing paper sheets. ing.

The fourth belt 4 is wound around a pulley 16 of the first belt 1 and a pulley 26 provided beyond the pulley 24 of the third belt 3. The three belts 4, 3 are arranged so as to be stretched against each other, and the belts 3, 4 are pressed against each other in the area between the pulleys 24, 26.

The delivery belts 5, 5 have a pair of belt configurations,
It is wound between the pulleys 27, 27 on the axes of the pulleys 17, 21 of the first belt 1 and the second belt 2 and a pulley (not shown), for example, to move paper sheets toward the paper sheet storage section. It is designed to be transported.

The course stopping member 6 is located at a position immediately before the first belt 1 is folded back by the pulley 16.
It is provided movably between a protruding position that intersects with the first belt 1 (the position shown by the solid line) and a position where it retreats outside the first belt 1 (the position shown by the chain line), and in the embodiment, the base is attached to the shaft 28. This shaft 28 is connected to a plunger 30 of a solenoid 29 which is a driving means 9, takes a retracted position when the plunger 30 advances, and crosses the conveying surface of the first belt 1 when the plunger 30 is retracted. It is designed to be projected in a certain position.

The endless belt 7 includes a roller 31 provided on the shaft of the pulley 15 at a position corresponding to the starting end of the outgoing path 11 constituted by the first belt 1, and a spring 32 provided oppositely behind the roller 31. The portion 7A is held between the pressure roller 33 which is urged toward the roller 31 side by the pulley 15, and is made of a flexible and elastic material such as rubber and has a larger diameter than the pulley 15 and is freely deformable.
The part 7A, which is normally free to deform due to its own elasticity, crosses the first belt 1 and the third belt 3, and is moved in the direction of the arrow via the roller 31 as the pulley 15 rotates. It is becoming more and more like this. In the figure, reference numerals 34 and 35 are guide members for guiding paper sheets, respectively.

In the above configuration, the length relationship of the conveyance path by each of the belts is such that the leading edge of the sheet is from the path stopping member 6 with respect to the sheet on the outgoing path 11 whose leading edge is located at the path stopping member 6. The length of the feeding path 13 that is moved by the first belt 1 to the confluence 12 of the inlets of the delivery belts 5, 5, and the rear end of the paper sheet on the outgoing path 11 whose leading edge is located at the path stop member 6. The movement locus distance in which the edge is moved from the forward path 11 to the return path 25 by the endless belt, and the joining from the position of the trailing edge of the paper sheet located in the return path 25 in the return path 25. The length of a portion of the return path 25 to point 12 is approximately equal to the length, and the distance from the path stop member 6 to the freely deformable portion 7A of the endless belt 7 is equal to the length in the feeding direction of the paper sheets to be handled. Sayori is much shorter. Each of the belts and the endless belt 7 are rotated by a single driving source through frictional contact between the belts and moved at the same speed.

Next, the operation of the above embodiment will be explained.

When the sheets to be processed are conveyed through the carry-in path 10 at regular intervals, the front and back sides are identified when they pass the installation position of the identification means 8, and when they are identified as cover sheets, the solenoid 29 is not energized. , path stop member 6
is placed in the retracted position shown by the chain line, and the cover sheet comes into contact with the endless belt 7 from between the first belt 1 and the second belt 2 (Fig. 3A), and while bending it downward, The belt 1 is held between the belt 1 and the freely deformable portion 7A of the endless belt 7 (FIG. 3B), and is fed for a while, and is then fed along the outgoing path 11 along the lower surface of the first belt 1.

At the time when the rear end of the cover leaf in the traveling direction is removed from the endless belt 7, the leading end of the cover leaf in the traveling direction is at the first position.
The conveyance path 1 is held between the belt 1 and the fourth belt 4.
3 to the confluence point 12, and is passed along the guide member 35 between the delivery belts 5, 5, and sent to the post-processing section.

On the other hand, if the identification means 8 identifies the sheet as a backing sheet while being fed through the carry-in path 10, the solenoid 29 is energized by the signal, and the path stopping member 6 is thereby moved along the feeding path as shown by the solid line. Stand out inward and wait.

The leading edge of the backing sheet sent along the outgoing path 11 in the same manner as described above comes into contact with the path stop member 6, and the rear end of the backing sheet is moved while bending the freely deformable portion 7A of the endless belt 7. Due to the belt movement of the endless belt 7, it is moved to the return path 25 side (FIG. 3C), and due to the belt movement of the endless belt 7, the rear end of the backing sheet is held between the endless belt 7 and the third belt 3. (FIG. 3D to E), and as a result, it is sent along the return path 25 with the rear end serving as the leading end without floating. Endless belt 7
After passing through the position, it is held between the second belt 2 and the third belt 3, reaches the confluence point 12, is passed along the guide member 35 between the delivery belts 5, 5, and is sent to the post-processing section. .

Therefore, when sent to the carry-out belts 5, 5, the cover sheets are conveyed in the same direction as the above-mentioned cover sheets, and when sent between the carry-out belts 5, 5, the forward path 11, Since the return route 25 has the same feeding time, the carry-in route 1 is used for the preceding cover sheets.
Since the conveyance belts 5 and 5 are fed at the same interval as the conveyance interval at 0, there will be no variation in the interval when they reach the post-processing section, and there will be no inconvenience in processing.

The energization of the solenoid 29 is demagnetized after a predetermined period of time has elapsed by a timer, for example, and the course stopping member 6 is demagnetized.
is returned to the retracted position again.

In addition, in the illustrated embodiment, the way in which the belts constituting each conveyance path are routed is not limited to the illustrated example, and the feeding direction and length of the paper sheets can be adjusted depending on the size and properties of the paper sheets to be handled. Of course, the design can be changed as appropriate.
