2. Description of the Related Art A bill processing apparatus built in a bill depositing / dispensing machine will be described below as an example. As shown in FIG. 7, the banknote handling apparatus includes a discrimination section 72, a front / back reversing section 73, a temporary holding section 74, and a return holding section 7 inwardly in communication with the deposit / withdrawal port 71.
5, the first to third money type stackers 76 to 78, the operation cartridge 79, and the recovery cartridge 80 are connected by a transport path 81 in a loop shape to allow deposit / withdrawal transactions and distribution / collection processing.

When carrying out the bills, for example, during the depositing process, as shown by the thick solid line in FIG.
The bills inserted into the discriminator are guided to the discriminating unit 72 for discrimination, and when the discriminated bills are on the back side, the bills are guided to the front and back reversing unit 73 to be reversed, and the front and back are aligned by this reversing operation, and then the temporary holding unit. It is temporarily suspended at 74.

At this time, if there is a defective banknote, the banknote is guided from the temporary holding section 74 to the return holding section 75 in the latter stage so as to be held for return, and after the deposit transaction is confirmed, as shown by a thick solid line in FIG. Are fed out one by one and distributed and stored in the first to third denomination stackers 76 to 78 corresponding to discrimination,
At this time, if there is an unfit banknote that is not suitable for circulation, it is collected in the collection cartridge 80.

By the way, as shown in FIG. 9, this type of front / back reversing unit 73 guides the banknote A guided to the reversal loading position to the front / back reversal side by the distribution plate 91 and conveys the banknote A guided therein. A push-out lever 96 that guides the bill A into the straight passage 94 for direction change by the roller 92 and the conveyor belt 93, and pushes the tip of the bill A carried into the straight passage 94 outward of the passage against the biasing force of the spring 95. By pushing out and carrying out the front and back of the banknote A in the opposite direction, the banknote A is redirected and pushed out, whereby the banknote A is guided to the original transport line 97 in a state where the front and back sides are reversed.

However, such a front-back reversing structure requires a long straight passage for direction change, and the device becomes large in size.
In addition, since the banknotes naturally descend in the internal space of the straight passage due to their own weight and move to a fixed position,
Stable reversal processing performance may not be obtained during reversal processing of banknotes, and since the front and back reversing unit has many parts and is complicated, there is a problem that bill jamming (jam) is easily induced.

[0007]

SUMMARY OF THE INVENTION Therefore, the present invention focuses on reversing the front and back by utilizing the restoring force of the paper sheet, and guiding the paper sheet to a curved front and back reversing passage to bend it. Therefore, it is an object of the present invention to provide a paper sheet transporting device having a high front / back surface reversing performance capable of stably reversing a paper sheet in a small space.

[0008]

According to the first aspect of the present invention,
What is claimed is: 1. A paper sheet transporting device comprising a front and back reversing means for reversing the front and back of a paper sheet on a transport path for transporting a paper sheet, the front and back reversing device comprising a transport guide member for transporting and guiding the paper sheet. It is characterized in that it has front and back reversing means in which the passage is curved.

[0009]

According to the present invention, when a paper sheet is guided to the front / back reversing passage, the paper sheet guided here is curved along the curved front / back reversing passage, and the curved paper sheet itself is original. The paper sheet naturally moves in the direction in which the paper sheet should be reversed due to the restoring action of returning to the straight stretched state.

[0010]

As a result, the paper sheet guided to the front / back inversion path naturally receives a restoring force due to the curving action of this path, and if this restoring force is moved in the front / back inversion direction, the paper sheet is returned. The restoring action of the leaf itself acts as if it were a spring, allowing it to move naturally in a specific space, and by simply providing this curved path, it is possible to move the paper sheet in the front-back inversion direction stably. it can.

Further, if the front and back reversing passages are formed in a curved shape close to a circle such as an inverted C shape, they can be formed in a small space and can be efficiently miniaturized. Further, since the front and back reversing springs and push-out levers can be omitted to reduce the number of parts, a simple front and back reversing structure can be realized, the transport system can be simplified and the cost can be reduced, and the jam suppressing effect can be enhanced at the same time.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to the drawings. FIG. 1 shows a banknote depositing / dispensing machine 11 installed at a staff window of a financial institution. The banknote depositing / dispensing machine 11 has a rectangular parallelepiped main body 12 on both sides of an upper surface, and a staff operation part 13 for depositing / dispensing operations. In addition, a bucket 14 for depositing and withdrawing bills is provided on an inclined upper surface that is inclined toward the front side of the apparatus main body 12.

FIG. 2 shows a banknote processing unit 21 which is built in the banknote depositing / dispensing machine 11. The banknote processing unit 21 is roughly divided into an upper transfer processing group 22 and a lower storage processing group 23. The conveyance processing group 22 communicates with the concave-shaped bucket 14 inward, a discrimination section 24 for discriminating the banknote A, a front / back reversing section 25 for reversing the banknote, and a collection box for collecting unfit banknotes and uncollected banknotes. 26, a temporary holding unit 27 for temporarily holding banknotes for return / acquisition, a return holding unit 28 for holding discrimination-defective banknotes and deposit-cancelled banknotes for return, and an upper transport line connecting these in a loop at the top. It comprises L1 and a lower transport line L2 which connects the discriminating portion of the upper transport line L1 as a common passage at a lower portion in a loop shape.

Of these, the upper transport line L1 has the transport start end set in the bucket 14 and the transport end end temporarily held in the storage section 2.
7, the return holding section 28, and the transfer branch position P in front of both the holding sections, the banknote A is allowed to be transferred in a loop on the upper transfer line L1.

In this case, the bucket 14 for taking in and taking out bills is provided by allowing tilting from the external corresponding position in the upright state to the inclined internal corresponding position. Normally, the bucket 14 is erected and the clerk is in charge from the upper opening. At an external corresponding position for moving in and out, and the bucket 14 is tilted from the external corresponding position to correspond to each internal corresponding position. For example, at the time of deposit transaction, the bucket 14 is connected to the upper transport line L1 at the internal corresponding position so as to allow the bills deposited in the bucket 14 to be taken into the inside. The lower side of the upper transfer line L1 is connected as a common line to the lower transfer line L2 in a loop shape, and the lower side of the lower transfer line L2 is incorporated into the storage processing group 23.

The lower storage processing group 23 is provided with operation cartridges 29 and first to third stackers 30 to 32 of different denominations, of which the operation cartridges 29 have the above-mentioned upper and lower parts through the operation transfer line L3. And the stackers 30 to 32 are connected to the lower transfer lines L1 and L2.
Is connected to the lower transport line L2 in a state where the lower side of the line is allowed to pass.

In this case, each of the stackers 30 to 32 has a carry-in port La for carrying in the banknote A on one side and a carry-out port Lb for carrying out the banknote A on the other side, and the stacker passes horizontally between them. Horizontally connected at line L4, and each stacker 3
0 to 32 carry-out port Lb of the stacker adjacent to the carry-out port Lb side
The banknotes are connected to the a side so that banknotes can be delivered. Therefore, the stackers 30 to 32 arranged in series are connected to the stacker passage lines L4 ... Which are continuous in the horizontal direction, and allow the bills introduced therein to pass.

When the banknotes guided from the lower transport line L2 are stored in the stackers 30 to 32, the banknotes are branched and transported at the branch position of the carry-in port La to be received and stored. Conversely, when the banknotes are discharged. The banknotes are delivered from the carry-out port Lb of the stacker and discharged.

3 and 4 show a front / back reversing section 25 connected to the upper conveyance line L1. The front / back reversing section 25 is arranged in a simplified structure of the front / back reversing structure after the discrimination section 24. The distribution plate 33 is arranged at the branch connection position of the upper transport line L1 in the vertical direction, and the banknote A guided to this branch connection position is provided on the same transport line L1 side in the upward direction and the front / back reversing section 25 side in the horizontal direction. Further, on the side of the front and back reversing unit 25, a curved passage 34 is arranged and formed for reversing the front and back of the taken-in bill A and rejoining it to the upper conveyance line L1.

The curved passage 34 is formed by curving an inverted C-shaped tapered passage capable of receiving one bill and curving the entire bill by surrounding it with upper and lower guide plates 35a and 35b, and the inner end of the passage is stopped. The lower guide plate 35b corresponding to the carry-in guide is extended to a position facing the distribution plate 33 described above, and is used as a carry-out guide. The corresponding upper guide plate 35a includes a large-diameter carrying roller 36 and a small-diameter carrying-out roller 3 corresponding to the carry-out side.
It is configured to extend between the carry-out section and the carry-out section 7.

As a result, the bill A guided to the curved passage 34 is carried in while substantially entirely curving into an inverted C-shape, and at the time of carrying in the curving, the bill A is bent and naturally straightened. When the leading end Aa of the bill A comes into contact with the inner end of the passage to stop the carry-in, the rear end Ab side of the bill in the original straight direction is used as the restoration fulcrum. While being restored, it moves to the upper space and is guided along the upper guide plate 35a between the rollers 36 and 37 corresponding to the carry-out side. This led bill A
Are carried out with the front and back reversed, and at the time of carrying out, they become face-up banknotes and are merged with the original upper transport line L1.

In this way, by simply guiding the curved passage 34,
The back-side bills A carried in here can be naturally moved in the front-reversal direction due to the momentary restoration characteristics of the bills themselves, and have a stable passage with a simple passage structure with few parts. The action is obtained.

When discriminating the bills conveyed in the face-up direction by the discriminating unit 24, the bills are not guided to the front / back reversing unit 25 side and, as shown in FIG. 4, go straight upward on the original upper transport line L1. And carry it to the subsequent stage.

Next, the transfer processing operation of the banknote processing device 21 will be described with reference to the transfer explanatory diagrams of FIGS. 5 and 6.
FIG. 5 shows a transfer processing operation at the time of a deposit transaction. Now, when the deposited banknotes A ... Are loaded into the bucket 14, the deposited banknotes A ... Inclined and connected to the internal upper transport line L1. , Is guided to the discriminating section 24 through the upper transport line L1.

Here, the authenticity, the denomination, the front and back, the degree of unfit banknote, etc. of the bill A are discriminated and, if valid, as shown in FIG.
After being guided to the front / back reversing unit 25 to reverse the front and back, and the banknote A having the front and back reversed, joins the upper conveyance line L1 again,
It is guided to the temporary holding unit 27 and temporarily held.

At this time, if there is a defective banknote unsuitable for the deposit transaction, the banknote is returned to the return holding section 28 and held, and then the returned banknote A is returned.
Is returned to the bucket 14. Similarly, in the case of canceling the deposit, the accumulated banknotes A temporarily held are returned to the original bucket 14.

FIG. 6 shows the storage processing operation of the deposited banknotes. When the deposit transaction is confirmed, the storage operation from the temporary holding section 27 is started. At this time, since the stacked banknotes A ... Held in the temporary holding section 27 have already been aligned in the front / back reversing section 25, the temporarily stacked banknotes A. Further, through the upper transport line L1 and the lower transport line L2, the money is stored in the first to third stackers 30 to 32 of the different denominations corresponding to the classification. At this time, all the stored banknotes are stored with their front and back aligned, and even when they are used for recycling such as withdrawal transactions, they can be delivered and processed as they are. In addition, if there is an unfit banknote banknote unsuitable for circulation during the carrying process, the collection box 2
It leads to 6 and collects it.

As described above, the banknotes guided to the curved passage of the front / back reversing portion are naturally subjected to the curving action of the passage to generate a restoring force. By moving this restoring force in the front / back reversing direction, The restoring force of the bill itself acts like a spring and can be naturally moved in the carry-out direction, and the bill can be stably moved in the front-back reversal direction only by being carried into this curved path. In addition, the curved passage is C
By making the curved shape close to a letter-shaped circle, it can be formed in a small space, and the front / back reversing portion can be efficiently miniaturized.
Further, since the number of parts for reversing the front and back can be reduced, a simple front and back reversing structure can be realized, simplification of the transport system can be promoted, cost can be reduced, and jam suppressing effect can be simultaneously enhanced.

In the correspondence between the present invention and the configuration of the above-described embodiment, the paper sheet conveying apparatus of the present invention corresponds to the banknote processing apparatus 21 of the embodiment, and hereinafter, similarly, the paper sheet is Corresponding to the bill A, the transport path corresponds to the upper transport line L1, the front / back reversing means corresponds to the front / back reversing section 25, and the transport guide member corresponds to the upper guide plate 35a and the lower guide plate 35b.
