Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an improvement in a paper sheet reversing device for reversing the front and back sides of banknotes, for example.

[Technical background of the invention and its problems]

In recent years, cash sorting and counting machines have been put into practical use that accept banknotes of multiple denominations all at once, automatically inspect them, and sort and count them, with considerable success.

This cash sorting and tallying machine is usually used for 10,000 yen banknotes, egg yen banknotes,
It has a configuration with four accumulation chambers for separately accumulating 1,000 yen banknotes and 500 yen banknotes.

However, in conventional cash sorting and counting machines of this type, when automatically aligning the front and back sides of four types of banknotes, four accumulation chambers are allocated two each for stacking front banknotes and two for stacking genuine banknotes. Two denominations, for example, 10,000 yen banknotes and egg yen banknotes, are designated and the front and back sides are arranged. Next, after taking out the stacked banknotes from each stacking chamber, the front and back sides of the banknotes other than those designated which were initially rejected, ie, 1,000 yen banknotes and 500 yen banknotes, are sorted. In this way, only two types of banknotes at most can be handled, and when four types of banknotes are handled, twice as much processing time is required, resulting in extremely low processing efficiency.

Therefore, in order to solve this problem, the upstream side of the sorting and stacking section is divided into those that require reversal and those that do not, and the banknotes that require reversal are reversed in advance and then merged again. We devised a system that allows four types of banknotes to be stacked face-to-face at the same time.

However, in order to put this into practical use, there is a need for a flipping device that is flexible and capable of reliably flipping folded bills without jamming or skewing them.

10,000, Typical conventional paper sheet flipping devices include a switch pack method in which the front end of the sheet is brought into contact with a stopper, and then the paper sheet is taken out from the rear end to turn the sheet inside out. There is a twisted conveyance path method in which a twisted conveyance path is formed by twisting 180 degrees at mutually opposing parts of the belts passed over the rollers, and the front and back are reversed.

However, since the former switch pack type leaves the paper sheet in a -H-free state, it is almost impossible to reliably flip the paper sheet upside down if the paper sheet does not have rigidity. This method cannot be applied, and there is a serious problem that there is a lot of time loss because the transport operation is temporarily stopped.

10,000 The latter type of twisted conveyance path flips paper sheets from front to back while holding them, so it is possible to turn relatively soft paper sheets from front to back. It is not possible to reliably turn paper sheets that are folded or worn out, are weak, and thin, and then handed over. In other words, in the conventional twisted conveyance path type, the belt forming the twisted conveyance path is driven using a plurality of drive rollers including a drive roller provided at the entrance side of the twisted conveyance path. The belt in the forming part rotates on the loose side, causing uneven belt speed, slack, and belt misalignment, which may impair the adhesion of the mutually facing parts of the belt or cause it to flap, causing the paper to become loose. This not only impairs the conveyance of the leaves, causing skew and jams, but also shortens the life of the belt.

[Purpose of the invention]

The present invention was developed based on the above-mentioned circumstances, and its purpose is to reliably fold or bend paper sheets such as banknotes without causing skew or jamming. It is an object of the present invention to provide a device for reversing paper sheets, which is capable of reversing the front and back sides and is capable of prolonging the life of a conveyor belt forming a twisted conveyance path.

[Summary of the invention]

In order to achieve such an object, the present invention provides a driving roller for driving the belt at one location on the exit side of the twisting conveyance path, and sets the portion forming the twisting conveyance path as the tension side, thereby preventing uneven belt speed, slack, etc. This is to prevent the belt from shifting.

Hereinafter, the invention will be explained with reference to an illustrated embodiment.

FIG. 1 is a schematic perspective view of a bill sorting and tallying machine to which an embodiment of the front-back reversing device of the present invention is applied, and FIG. 2 is a front view of the entire machine. In the figure, reference numeral 1 denotes a main body, and a display operation device 2 is provided at the upper right of the main body J, as well as a bill slot 3 and a bill reject tray. 5- The main unit 1 yen facing the bill slot 3 is provided with a bill ejecting device 5, and the bills P placed in the bill slot 3 are taken out one by one and taken in and conveyed. It's like being sent to the road 6 yen.

The banknotes P that have been set and taken out are passed through a discriminating section 7 that determines the banknote denomination, authenticity, whether it is normal or not, and whether it is front or back, etc., while being conveyed along the take-in conveyance path 6. Banknotes P determined to be abnormal by this discrimination section 7 are sent to the banknote reject trojan, and normal banknotes P are sent to the east gate to the left in the figure by a sorting gate 8. Further, the banknotes P determined as front by the above-mentioned discriminator 7 are guided to the first conveyance path 9, and the banknotes P determined as back are guided to the second conveyance path, i.e., by the second sorting dart 1°. The paper is led to a front-back reversing device 11 and corrected from the back to the front. Furthermore, the passage times of the first conveyance path 9 and the second conveyance path (front/back reversal conveyance device) 11 are set to be the same passage time, and banknotes P..
When the 6- and 6- are sorted by the second sorting gate 10 and pass through separate conveyance paths 9 and 11 and merge at the merging section 12, they are conveyed at a constant pitch without colliding or pitch clogging. It looks like this. Furthermore, the banknotes P whose front and back sides are aligned are transported to the confluence section 12.
The denominations are conveyed to a sorting conveyance path 13, which serves as a sorting section connected to the bank, and are sorted by denomination. Below the sorting conveyance path 13, there is a stacking device 14a that stacks banknotes sorted by denomination in a sequentially stacked manner in the plane direction.
14 b , 14 c , 14 d and the banknotes P stacked on these stacking devices 14 a , 14 b , 14 c , and 14 d
. . . and, if necessary, the storage 15a,
A shutter device 16 is provided to allow storage in 15b, 15c, and 15d. Furthermore, each storage 15a-1
A pushing device 17 for pushing the banknotes P... is provided to ensure storage in the banknote 5d.

Next, the second feeding path, that is, the front-back reversal conveying device 11
will be explained with reference to FIGS. 2 to 6 (a), (b), and e.

In FIG. 3, 20 is a twisted conveyance path twisted by 180', and this twisted conveyance path 20 is 7 as shown in FIG.
It is formed by stretching a stretchable endless belt 21 (hereinafter referred to as a twist belt) 21 twisted by 20 degrees (two turns) through a plurality of rollers 22a to 22f in a figure 8 shape. Furthermore, as shown in FIG.
A flat twist guide body 23 &
, 23b, 23C, and 23d are arranged. These flat plate-like twisting guide bodies are supported by the support supports shown in the figure, and the guide bodies 23&, 23b, 23c, and 23d are also paired as shown in FIG. 6(a) in accordance with the twisting of the twisting belt 21. It is twisted to maintain the gap ai. These twisting guide bodies 23h to 23c are located on both sides of the twisting belt 210 and are continuous from the entrance to the exit of the twisting conveyance path 20, so they are effective for bills P that are folded in four, folded in half, or have a weak texture. The purpose of this is to fold the banknote P into four and twist it around the belt 21.
When conveyed in a 180° inversion at high speed, the wind pressure can cause the receiver to break or skew (SKEW), as shown in Figure 6 (b). In order to prevent this and to perform a stable reversal conveyance system, it is necessary to securely tighten both ends and guide them. The pair of guide bodies 23h and 23b, and the pair of 23c and 23d fulfill this role. are doing. Further, in the figure, reference numeral 24 denotes an idle roller located at the center of the reed twisting belt 21, which provides a clamping force for the banknote P. This is because the twisting belt 21 tries to restore its original shape, so no conveying force can be expected on the twisting conveyance path 20.

Furthermore, when the bill P is conveyed while being reversed on the twisting conveyance path 20, it is conveyed in the shape shown in Fig. 6 e (this is caused by the twisting of the twisting belt). There will be a collision. Therefore, the rollers 24 and 25 located on the twisting conveyance path 20 are connected to the twisting belt 21.
It is necessary to have a width C that is equal to or less than the width of the . (6th
(See Figures (a) and (b)) Also, the banknote P is
Since the banknotes are forcibly twisted, they tend to get bent, and if they merge with the front banknotes P that are being conveyed from the first conveyance path 9, they are likely to jam. Therefore, a flat conveyance path, such as the horizontal conveyance path 26, is required to correct the curl after reversal. As shown in the box in FIG. 5, at least the horizontal conveyance path 26 for one banknote is configured to merge after correction.

The υ belt 21 is driven by a drive belt 27 from the motor 18 shown in FIG.
8 to rotate the conveyor belt forming the intake conveyance path 6. Furthermore, the drive belt 29 is connected to the drive roller 2.
8 and 30 degrees 226, and the second conveyance path (front-side reversal conveyance device) 11. A conveyor belt constituting the divided conveyance path 13 rotates. Further, the drive belt 32 is a drive roller 22d, s:9.

34 is passed to the first conveyance path 9 and the reject conveyance path 3.
A conveyor belt constituting 5 rotates.

Also, among the rollers 22a to 22f, the twist conveyance W
Only the roller lO-22d provided on the river mouth side of the belt 20 serves as a driving roller, and the portion of the belt 21 that forms the twist 9 conveyance path 20 and the horizontal conveyance path 26 becomes the tension side, which prevents uneven speed of the belt 21. This prevents sagging, misalignment, etc., and reliably turns the paper sheet P upside down without causing skew, jam, etc. When the motor 27 runs in this manner, all the transport systems rotate at the same speed. Also, the conveyance distance between the I-th conveyance path 9 and the second conveyance path (front-back reversal conveyance device) 1 is as follows:
Although they are set to be the same, the passing times are not necessarily the same due to belt and roller slips, etc. By moving the roller 36 for correcting the passage time of the conveyance path 9 of the high-grade 1 as shown by the broken line in FIG. 2, the conveyance distance can be corrected and the passage time can be made to match that of the second conveyance path (front-side reversal conveyance device) 11. It looks like this.

In this way, the banknote pitch at the confluence section 12 of the cloudy banknotes that have passed through the first conveyance path 9 and the banknotes P that have passed through the second conveyance path (front-side reversal conveyance device) 11 is the second.
The pitch of the banknotes is exactly the same as the banknote pitch in front of the gate 10, and the configuration is such that the order of the banknotes is not changed, the banknotes do not collide, and the operation timing is not impaired.

Then, the banknotes P conveyed through the belts in the take-in conveyance path 6 are discriminated by the discriminating section 7, and the banknotes P which are determined to be genuine or false or abnormal are checked by the first sorting gate 8. The banknotes are distributed to the banknote transport section. Next, even normal banknotes P that are recognized as front banknotes are guided to the first conveyance path 9, and banknotes P that are recognized as reverse banknotes are sorted out at the gate 10 and transferred to the second conveyance path 9.
is guided to a conveyance path (front-back reversal conveyance device) 11. Here, the banknote P determined to be the back is reversely conveyed by the twisting belt 21, but both ends of the banknote P are connected to the guide pairs 23a to 23.
d, the genuine banknote P is conveyed in a 180° inversion while being securely rolled by the pack-up guide, and corrected to the front banknote P. After correcting the curl in the twisting conveyance path 20 and the horizontal conveyance path 26, the above-mentioned merging is carried out. In the section 12, the cloth banknotes P sent out from the first conveyance path 9 are merged and conveyed without the pitch between the banknotes being out of order.

The same effect can be obtained even if the twist guide bodies 23a-23d are replaced from flat plate-shaped ones to wire-shaped twist guides 37a-J7d with round cross sections as shown in FIGS. 7 and 8.

In other words, the banknote P has a twisted conveyance path, ? Because it is rotated by 0'1180° and conveyed, the twisted conveyance path 20 is rotated in Fig. 9 (A)←
), the lead angle θ (taflθ=
Even if the wire-like twisting guide bodies 97a to 3rd formed by winding helically at the angle 2b), 97a to 3rd, are attached to both sides of the twisting conveyance path 200, they can back up the shaking of both ends of the banknote P and guide it. You can.

In addition, the classified conveyance path 13 separates banknotes P for each denomination, which are conveyed via the first conveyance path 9 and the second conveyance path (front-back reversal conveyance device) 11 and merged at the merging section 12. It separates the stacking devices 14h to 14d, and is configured as follows. That is, as shown in FIGS. 10 and 11, the divided conveyance path 13 includes a conveyor belt 41 stretched across a plurality of guides 13, rollers 40, etc., and a substantially horizontal lower surface of the conveyor belt 41. The banknotes P are conveyed while being held in the direction of the arrow at the mutually opposing surfaces with a plurality of conveyor belts 43, which are stretched through guide rollers 42, respectively, so that a part of the conveyor belts come into contact with the conveyor belts. There is.

Further, at a position corresponding to the 1N-th third integrating devices 14a to 14c, there is a vibrating molecule 44a which can be rotated by a rotary lens (not shown).

44b, 44c are arranged, and the banknotes P... that are about to go straight in the direction of the arrow are appropriately stacked in the stacking devices 14a to 14e.
It is now possible to lead it to the side. Further, the banknotes P sorted by the sorting group 44a+44b r44c are moved to the substantially vertical part of the conveyor belt 43 and the idle roller 45 so that a part of the paper comes into contact with this substantially vertical part.
45, and a conveyor belt 46 which is stretched across the conveyor belt 46. - In addition, the banknotes P guided to the fourth stacking device 14d are formed by the mutually opposing surfaces of the conveyor belt 41 and the conveyor belt 43 at the right end in FIG. It looks like this. The segmented conveyance path 13 configured in this way sequentially conveys the banknotes P sent out from the merging section 12 through the conveyor belts 4 and 43 through the conveyor belts 4, 43, and so on in the short direction after sandwiching them. . If the denomination of the banknote P to be conveyed is, for example, a 100 yen banknote as a result of the denomination determination by the discriminator 7, the rotary solenoid (not shown) is energized and the sorting case 44a is opened. The banknote P is movably displaced from the state shown in FIG. 1O to the position shown by the solid line in FIG. After this, the rotary lenoid (not shown) is demagnetized and the section 1''-toad 44a is returned to the state shown in FIG. 10 (the state shown by the two-dot chain line in FIG. 11). The sorting dart 44b operates in the same manner as described above, and in the case of a thousand yen bill, the sorting dart 44c operates in the same manner as described above.5
In the case of a 100 yen bill, it is naturally conveyed and guided to the end of the sorted conveyance path 13 without being sorted on the way. The banknotes P... guided to the sorting conveyance path 13 are sorted by denomination in this way. Next, the above-mentioned stacking devices 14a, 1 stack the banknotes P separated by denomination in this way.
4b, 14c, and 14d in Figures 10, 11, and 1.
This will be explained based on FIG. A first accumulation device 14a provided below the division dart 441L, and a second accumulation device 14 provided below the division gate 44b.
b, the above-mentioned division) The third accumulation device 14c provided correspondingly below the f-to 44c and the fourth accumulation device 14d provided correspondingly below the terminal end of the sectioned conveyance path 13 are approximately equivalent. After being sorted by the sorting darts 44a to 44c, the banknotes P are carried out by the carry-out path 47... or the banknotes P are carried out directly from the terminal end of the sorting conveyance path 13. Each banknote is composed of an impeller mechanism 5θ for stacking banknotes in the surface direction, and a stacking chamber 51 for guiding and stacking the sides of banknotes. The specific structure of the impeller mechanism 50 and the accumulation chamber 51 is shown in FIGS. 11 and 12, in which a support shaft 52 is supported by a bearing 54 provided on a side frame 53. A driven gear 55 is fitted onto the support shaft 52 . The support shaft 42a of the guide roller 42 is attached to the side frame 53, and an intermediate gear mechanism 57 is provided between the drive gear 56 fitted on the guide roller 42 and the driven gear 55. , when the guide roller 42 is rotated by the rotation of the drive belt 29, the drive gear 56. Intermediate gear mechanism 57
．． The rotational force is sequentially transmitted to the driven gear 55 so that the impeller 58 attached to the intermediate portion of the support shaft 52 rotates. The impeller 58 includes a ring-shaped impeller main body 58a,
A plurality of blade plates 58b whose base end portions protrude radially from the support shaft 52 on this circumferential surface and are bent in a predetermined direction.
It is composed of... Further, each blade plate 58b is formed in a spiral shape with a wide spacing between the tip ends and gradually narrowing toward the base end. Moreover, the impeller 58.58 is connected to the fold line Pa of the banknote P as shown in FIG.

It is installed outside of Pb.

Although it is not shown in the figure, it goes without saying that folds can be avoided even if the bill P is folded in two, and especially when setting the interval between the impellers 58 and 58, If a large 100 yen bill is used as a standard, folding can naturally be avoided for low-denomination bills as well. By arranging the impellers 58, 58 in this way, it is possible to reliably prevent banknotes from jamming at the vane plates 58.58 even if the banknotes P have some creases. In addition, each of the accumulation chambers 51... is connected to the blade plate 58 as shown in FIG. 1.1.
b, notches 59m, 59a so that 58b can pass through.
The left side wall plate 59 has a side wall plate 59, and the right side wall plate 60 is arranged opposite to the left side wall 59 with a space where banknotes P can be piled up and piled up in the surface direction. A plate 61 is provided so as to be openable and closable. Each of the wall plates 59..., 60... has a linear convex portion 59b along the falling movement direction of the banknotes P, that is, the overlapping direction of the banknotes P (direction of arrow F shown in FIG. 11).
. . , 60b . . . are formed, and at least the surface thereof is made of a conductive plate material, such as an engraved metal plate. If each of the wall plates 59, 60 is constructed of a metal plate constructed in this manner, the contact area with the banknote P can be reduced, so that the banknote P can be dropped smoothly, and the impellers 58, 58 and conveyor The static electricity generated on the banknote P due to contact with the belt 41, 43, 46 is transferred to the linear convex portion 59b of the wrapped metal plate...
60b..., so that it is possible to completely eliminate abnormalities in the falling of banknotes P and uneven accumulation due to the influence of static electricity. Note that the can wall plates 59 and 60 may be replaced with those constructed by conductive plating on the surface of an Endless FCF plastic plate.

The operation of the thus configured integration devices 14a to 14d will be explained. The banknotes P sorted by denomination by the conveyance path 13 as the sorting section are conveyed to any one of the first stacking device 14a to the fourth stacking device 14d according to the denomination.9 , for example, the first integration device 14a

Side partition plate 65a65bf can prevent manual opening, and can store banknotes P and
It has the unique effect of ensuring the safety of...

Next, the operation of the shutter device 16 will be explained. When a predetermined number of sheets have been placed in the stacking chamber 51V'3, the motor 81 is energized to rotate the drive shaft for a predetermined period of time, thereby stopping the rotating arm 82 at the position shown by the two-dot chain line in FIG.

The end roller 83 of the rotating arm 82 comes into contact with the arm 76
When the arm 76 leaves the bent portion 76a, the arm 76 is instantly rotated by the force of the spring 80, the first partition plate 65h moves in the 01 direction in the figure, and the second partition plate 65b moves in the G direction.

Further, 84 is a stopper of the arm 76. Further, 85 is a detector which detects that each partition plate 65a, 65b is opened. Further, 86 is a stop detector that detects whether each partition plate 65a, 65b is closed. Next, the partition plate 6
5a and 65b, when the operation of the pushing device 17, which will be described later, is completed and a predetermined detection is made, the motor 81 is re-energized and the rotating arm 82 is rotated in the direction of arrow A in the figure. When the arm 76 is rotated by a predetermined amount, the arm 76 comes into contact with the bent portion 76a of the arm 76, and the arm 76 is rotated against the biasing force of the spring 80. When detected by the stop detector 86, the motor 81 is activated. It appears as if the rotation has stopped. In such a shutter device 16, a plurality of stacking sections 51 from the first stacking device tj1.14a to the fourth stacking device J4d are connected to each other by four first partition plates. 65a and four second partition plates 65 connected to each other.

・As the banknotes P placed inside can be stored at the same time, the cost can be reduced to a minimum compared to the conventional system which consists of one shutter device for one accumulation chamber 51. In addition, since only one shutter device is used for the multiple collection rooms 5, the failure rate can be reduced, etc., resulting in cumulative effects.

In addition, in order to allow the group of banknotes P placed horizontally to freely fall horizontally without tilting, it is necessary to instantaneously operate each partition plate 65a, 65b. By selecting the spring 80, the operation can be made as fast as possible, and the configuration is very simple.

The pushing device 17 is shown in FIGS. 13, 15 and 1.
This will be explained with reference to FIG. The specific structure of the pushing device 17 is as shown in FIGS. 13, 15, and 16, and includes a side frame 53 fixed to the frame 1 and a vertically movable device fixed to the side frame 53 at one end. Is there a fixed N on the movable slide rail 90 and the moving side 90h of this slide rail 90?

As shown in FIG. 15, the banknotes P... moved downward, entered the storage compartments 15a to 15d, and fell to the end.
・It is designed to be stored by pushing it in. Further, when the arm 10θ rotates 180°, the frame 91 reaches the bottom dead center, which is detected by the detector 105, and the pushing operation is completed. In other words, the mechanism is such that the frame 9 moves back and forth once when the arm rotates 10,001 times. Moreover, many of the banknotes P... placed in the respective accumulation chambers 51... are stacked in a standing state as shown in the first accumulation chamber 51 in FIG. P can also be reliably pushed in and stored. That is, the 13th
As shown in the figure, the valley wall plates 59 of each of the accumulation chambers 5,
60 has linear convex portions 59b and 6 in the falling movement direction of the banknote P.
0b is formed, and these linear convex portions 59b..., 6
The pushing member 92 has notches 92a so that the bills are inserted in the same manner as 0b..., and is configured to be able to reliably push and store bills that are not stacked horizontally. In such a pushing device 17, the banknotes P... accumulated in the plurality of accumulation chambers 51... can be reliably stored into the plurality of storages 15a to 15d at the same time by the - operation, In contrast to the conventional configuration, where the first to fourth stacking chambers and storage compartments are each made up of independent pushing devices, the first to fourth stacking compartments and storage compartments are moved in one operation. Since it is configured to push in all at once at the same time, only one driving device is required, the number of parts is small, and the cost can be reduced to an average level, which has a great effect. The display operation device t2 is as shown in FIG.
, numeric keypad 113. Operation key group 114° display section 115.
It consists of a card insertion slot 116 and a slip issuing slot 117. The mode selection switch 111 is used to designate a processing mode such as classification, counting, or counting classification.

The operation key group 114 includes a denomination designation key 114c.

Operator number key 114g and total key 114
It is composed of h, etc. In addition, the display section 115
A display 115h that displays the number of coins for each denomination, a display 115b that displays the number of stacked coins for each stacking section, a display 115c that displays the total amount, and a display 11 that displays the total number of coins.
59. The operation of the display operating device 2 that has been constructed and operated in this way will be explained. For example, by setting the mode designation switch 111 to counting classification, the control section (not shown) can be set to counting classification mode. Then, insert the account number key 114b and enter the account number indicating the savings account on the numeric keypad 113.
, input the processing number 1140, input the operator number key 114d, and input the operator number key of the operator using the numeric keypad 113.

The account number, processing number and operator number entered using the numeric keypad 113 are displayed on the display 115e and confirmed. Then, the banknotes P deposited in the ordinary deposit are mixed into the input slot 3, regardless of whether they are of 4 denominations (front or back).
all at once while standing, and then turn on the start key 114f. Then, the banknote P is transferred to the ejecting device 5. Conveyance path 61 discrimination unit 7. Furthermore, banknotes that are determined to be clothed banknotes by the discriminator 7 pass through the first transport path 9, and banknotes that are determined to be back banknotes pass through the second transport path 11, where they are corrected to front banknotes and merged into the merging unit 12. Sectional conveyance path 13. Accumulating device 14, shutter device 16. The banknotes are stored in the storage 15 via the pushing device 17, and the number of banknotes for each denomination determined by the discriminating section 7 on the way is displayed on the display section j 1 #IL in correspondence with the stacking section and the denomination.
, 115b, and the total amount deposited is displayed on the display 115c. Thereafter, when the operator inputs the print key 1156f, the control unit (not shown) prints out the account number, processing number, operator number, number of coins for each denomination, amount, and total number and amount using a printer not shown. or,
Time deposits and savings deposits operate in the same manner as described above, and the number of coins for each denomination, total amount, etc. are processed together with the account number processing number and operator number.

Although the description has been given of a crank mechanism using a pair of bevel gears 96.98 for the pushing drive, other methods are also possible. For example, the same effect can be obtained by using a goal screw at one end of the frame 91 for reciprocating movement, or the same effect can be obtained by replacing it with various mechanisms such as a chain or belt transmission. Needless to say.

Note that 120 in the figure is a banknote detector that detects the presence or absence of banknotes P.

Note that the present invention is not limited to the above embodiments. That is, although the description has been given of a device that is applied to a banknote sorting and tallying machine to turn the front and back of banknotes, it goes without saying that it may also be used to turn over paper sheets other than banknotes.

Further, although the front/back reversing device has a twisting conveyance path and a horizontal conveyance path that are continuous, the present invention is not limited to this.

In addition, it goes without saying that the present invention can be modified in various ways without departing from the gist of the invention.

〔Effect of the invention〕

As explained above, the present invention provides a method for transporting paper sheets in which a belt is passed over a plurality of rollers to form a twisting conveyance path at mutually opposing portions of the belts, and the paper sheets can be turned over. In the front-back reversing device 33-, the front-back reversing device for paper sheets is characterized in that a drive roller for driving the belt is provided at one location on the exit side of the twisting conveyance path.

Therefore, the portion forming the twisting conveyance path can be made of one driving roller, and the shifter 11) can also be set on the tension side, thereby preventing belt speed unevenness, slack, belt slippage, etc., and preventing folding of banknotes, etc. Even paper sheets with low stiffness can be reliably turned inside out without skewing, jamming, etc., and the service life of the twist belt can be extended.
