DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet processing apparatus for processing sheets incorporated in a vending machine or the like, and a sheet feeding mechanism used in the sheet processing apparatus. The present invention relates to a paper sheet feeding mechanism characterized by a separation mechanism that can reliably feed out paper sheets one by one, and a paper sheet processing apparatus using the paper sheet feeding mechanism.

[0002]

2. Description of the Related Art Referring to FIG.
An outline of No. 11 will be described. As shown in the figure, the conventional bill feeding mechanism 111 is provided in the banknote safe 103, a part of the outer peripheral portion is raised, and the raised portion is the uppermost layer of the banknotes vertically stacked in the banknote safe 103. The timing roller 112 intermittently feeds out the first bill, which is one of the above, a feed roller 113 that feeds out the fed bill, and a gap roller 114.

When the first banknote is fed by the timing roller 112, the second banknote is also moved in the banknote feeding direction (hereinafter referred to as the feeding direction) due to the frictional force between the banknotes. Also moves in the feeding direction, and the stacked banknotes abut on the gap roller 114.

[0006] A predetermined gap is provided between the feed roller 113 and the gap roller 114 so that the fed bills pass one by one. The rotation direction of the feed roller 113 and the gap roller 114 when the bill is fed is counterclockwise in the drawing.

As shown in FIG. 7, after the first bill is fed, the feed roller 113 rotates in the reverse direction (clockwise in the drawing), and the second and subsequent bills are rotated by the reverse rotation of the feed roller 113. Returns to its original position.

[0006]

According to the above-described bill feeding mechanism, a plurality of bills may be fed in a stacked manner, which causes a bill jam in a bill processing apparatus using the bill feeding mechanism. Was. SUMMARY OF THE INVENTION It is an object of the present invention to provide a bill feeding mechanism that can reliably feed out bills one by one, and a bill processing apparatus that uses the bill feeding mechanism and does not cause bill jams.

[0007]

In order to achieve the above object, a paper sheet feeding mechanism according to the first aspect of the present invention will be described with reference to FIG.
, A timing roller 12 for intermittently feeding sheets stacked on a mounting surface;
A feed roller 13 for further feeding the paper fed in Step 2; and a gap roller 14 for regulating the paper fed in the feed roller 13, and a rotation center line substantially parallel to the rotation center line of the feed roller 13. Rotating around the center, the outer peripheral surface of the gap roller 14 and the feed roller 13
A gap roller 14 disposed with a predetermined gap from the outer peripheral surface of the feed roller; one end of which is fixed in a plane passing through the rotation center line of the feed roller 13 and substantially perpendicular to the mounting surface or in the vicinity of the flat surface; And a sheet-shaped flexible piece 15 whose free other end is arranged to be able to contact the feed roller 13.

The timing roller has a shape in which a part of the outer peripheral portion is raised. When the raised portion of the outer peripheral portion comes into contact with the surface of the paper sheet, the paper sheet is fed out, so that the paper sheet is fed out intermittently, and as a result, is fed out one by one. Since the feed roller is in contact with the free other end of the flexible piece, when further feeding out the sheet fed by the timing roller, the other end is pushed in the feeding direction. Therefore, the flexible piece bends and partially winds around the gap roller. The fed paper sheet comes into contact with the flexible piece, but the feeding is regulated by the gap roller via the flexible piece. Since only the frictional force from the upper layer sheet acts as a repetitive output on the other sheets than the first sheet as the uppermost layer, the sheet is further fed by the regulating force through the flexible piece of the gap roller. There is no.

[0009] The outer peripheral surface of the gap roller and the outer peripheral surface of the feed roller are disposed with a predetermined gap. The predetermined gap is set so that only one sheet can pass. Therefore, only the first sheet is
The paper is fed out through a gap between the feed roller and the gap roller. Here, the uppermost layer means the layer closest to the feed roller. When there is only one banknote, the banknote is the topmost banknote.

The fixed end of the flexible piece is fixed in or near a vertical plane that typically passes through the centerline of rotation of the feed roller. The free other end of the flexible piece may be cut, for example, so as to be parallel to the rotation center line of the feed roller.

[0011] It is preferable to form a chamfer on the leading end side of the raised portion formed on the outer peripheral portion of the timing roller in the feeding rotation direction. By chamfering, it is possible to prevent an impact on the stacked paper sheets and to smoothly feed out one sheet at a time.

According to a second aspect of the present invention, in the sheet feeding mechanism according to the first aspect, the sheet feeding mechanism is provided adjacent to a side surface of the gap roller for guiding the flexible piece. And a guide including an outer peripheral surface having a radius substantially equal to the radius of the outer peripheral surface of the gap roller.

According to the guide of the guide, the flexible piece can be bent in close contact with the guide, and the gap roller can more effectively regulate the paper sheet through the flexible piece. The center of the outer peripheral surface of the guide is substantially on the extension of the rotation center line of the gap roller. When the outer peripheral surface of the guide is viewed from the direction of the rotation center line of the gap roller, the guide is arranged such that the outer peripheral surface of the guide overlaps a portion of the outer peripheral portion of the gap roller closest to the feed roller and a portion in the vicinity thereof. .

The free other end of the flexible piece is tightly wound along the outer peripheral surface of the guide as the feed roller rotates.
When the flexible piece is completely wrapped around the guide, the other end has a length almost reaching a plane including the rotation center line of the feed roller and the rotation center line of the gap roller, or is located slightly before this plane. A flexible piece may be formed to have a length.

According to a third aspect of the present invention, in the paper sheet feeding mechanism according to the first or second aspect, the flexible piece comprises a sheet to be fed and the flexible piece. Is formed of a material having a friction coefficient larger than that of the paper sheets.

The feed roller applies a pressing force perpendicular to the paper sheet (first paper sheet) in contact with the feed roller and a repetitive output in the longitudinal direction of the paper sheet. Let it work. The second sheet (the sheet on the opposite side of the first sheet from the feed roller) via the first sheet
, A pressing force by the feed roller acts. The surface of the second sheet opposite to the first sheet at the place where the pressing force of the second sheet acts is in contact with the flexible piece.

When the first sheet is fed, the second sheet has a repetitive output obtained by multiplying a friction coefficient between the sheets by a pressing force, and friction acting between the flexible piece and the sheet. The force exerts a resistance force against the repetitive output. If the second sheet is not fed, this resistance is equal to the repetition output,
Since the maximum value of the resistance is a value obtained by multiplying the pressing force by the friction coefficient between the second sheet and the flexible piece, the repetitive output acting on the second sheet is the resistance of the second sheet. Never exceed power. Therefore, the second sheet is not fed out.

According to a fourth aspect of the present invention, in the sheet feeding mechanism according to any one of the first to third aspects, the feed roller is provided on an outer peripheral surface thereof. Characterized in that it has a knurl formed substantially parallel to the rotation axis of the knurl.

It is desirable that the knurl has a gear shape parallel to the rotation axis. The length of the flexible piece is such that the free end of the straight flexible piece collides with the knurl and the knurl is further rotated in both directions by a predetermined angle (for example, 20 degrees) in a state of being tangled with the knurl. Good to decide. Since the feed roller has a knurl, a repetitive output sufficient to reliably feed the sheet can be applied to the first sheet. In addition, since the feed roller has a knurl, the guide can be bent so as to be in contact with the free other end of the flexible piece so that the flexible piece is securely brought into close contact with the outer peripheral surface of the guide. The effect of regulating classes can be made to work satisfactorily.

For the same reason, after the first sheet is fed, the feed roller is rotated in the reverse direction to deflect the flexible piece in the anti-feeding direction, so that the sheet is slightly separated from the original gap roller. Can be returned to the original position. Since the sheets return to the original position before the feeding operation in this way, when the feed roller rotates in the feeding direction, the sheets can be fed at regular intervals.

It is preferable that at least one of the outer peripheral surface of the feed roller and the outer peripheral surface of the gap roller is formed of a plurality of cylinders. Further, a circumferential groove is formed between the plurality of cylinders, and the roller having the other outer peripheral surface that is not the outer peripheral surface formed of the plurality of cylinders has a width corresponding to the width of the groove, It is good to arrange in the center axis direction position corresponding to the groove.

The distance between the center axis of the feed roller and the center axis of the gap roller is preferably adjustable.
The gap between the outer peripheral surfaces of both may be substantially the same as or slightly smaller than the thickness of the paper sheet to be fed.
When the gap is small, the paper sheet is so-called habit-formed, the rigidity of the paper sheet is increased, and the paper sheet can be smoothly fed.

According to a fifth aspect of the present invention, there is provided a paper sheet processing apparatus according to the first to fourth aspects.
And a transport mechanism that transports the bills fed by the paper sheet feeding mechanism.

Since the paper sheet processing mechanism for reliably feeding out the paper sheets one by one is used, a paper sheet processing apparatus which is less likely to cause paper jams can be provided.

It should be noted that paper sheets refer to bills, cash notes, securities, and the like.

[0026]

Embodiments of the present invention will be described below with reference to the drawings. In the drawings, the same or corresponding members are denoted by the same reference numerals, and redundant description will be omitted. FIG. 1 shows a banknote processing apparatus 1 as a paper sheet processing apparatus having a banknote feeding mechanism 11 as a paper sheet feeding mechanism according to the present invention in a safe section.

A 1,000-yen bill inserted into the insertion slot 70 from the outside,
The five thousand yen bills are the mounting table 432 of the thousand yen safe 400, respectively.
It is stored on the mounting table 532 of the 5,000 yen safe 500. How the inserted 1,000 yen bill and 5,000 yen bill are
Whether it is stored on the P. 32 will be described later. The stored 1,000-yen bill and the 5,000-yen bill are paid out by the banknote pay-out mechanism 11 from the 1,000-yen safe 400 and the 5,000-yen safe 500, respectively, when it is necessary to pay them out as a fishing bill or when the transaction is canceled. Then, it is sent to the 10,000 yen safe 600, and when the 10,000 yen bill is also returned (only in the case of cancellation of the transaction), this is also returned to the outside collectively including this.

Next, with reference to FIG. 2, the structure of the bill feeding mechanism 11 in the case of the 1,000 yen safe 400 will be described. The configuration of the bill feeding mechanism 11 in the case of the 5,000 yen safe 500 is the same as that of the 1,000 yen safe 400.

The bill feeding mechanism 11 is provided in a safe section 420 of the 1,000 yen safe 400 (see FIG. 1), and rotates counterclockwise in the figure to intermittently feed a 1,000 yen bill. Rotate counterclockwise to rotate the timing roller 12
Roller 1 for further feeding the bills fed to
3. It includes a gap roller 14 that is freely rotatable and a rubber plate 15 as a flexible piece.

The timing roller 12 is for feeding out a 1,000-yen bill stored on a mounting table 432 in a safe section 420 of a 1,000-yen safe 400, and a portion outside the base circle section 16 (about 200 in angle). The outer peripheral portion 17 having a concentrically raised shape is formed on the inner wall 42 of the safe portion 420.
1 (see FIG. 4) is supported by a shaft 18 mounted vertically and horizontally. The base circle 16
The uppermost layer of the stacked 1000-yen bills, that is, the first 1000-yen bill, does not come into contact with, but has an arc-shaped outer peripheral portion 1
7 is arranged so as to be in contact with the surface of the first 1,000-yen bill.

When the 1,000 yen bill of the outer peripheral portion 17 of the timing roller 12 is fed out, the chamfered portion 19
Has been processed. On the shaft 18 on the opposite side of the timing roller 12 in the drawing (left side in the drawing in the feeding direction),
A gear 20 (indicated by a dotted line in the figure) is attached.

As shown in FIG. 4 (a cross-sectional view taken along the line AA in FIG. 2, but omitting the thousand-yen bill and showing the outer peripheral portion 17 on the lower side), the lower side of the inner side wall 421 of the safe section 420 is shown. Is attached with a horizontal billboard 433, an opening 433A is formed in the billboard 433, and the base circle portion 16 of the timing roller 12 does not protrude downward from the opening 433A, but has an outer peripheral portion 17A. Is configured to protrude downward from the opening 433A.

Further description will be made with reference to FIGS. 2 and 5 (cross-sectional view taken along the line BB in FIG. 2). A feed roller 13 is provided downstream of the timing roller 12 in the feeding direction.
The feed roller 13 is configured to include three small rollers 13A, 13A, 13A coaxially arranged in parallel and in parallel. The feed roller 13 is supported by a shaft 21 that is perpendicular and horizontally attached to the outer wall 422 of the 1,000 yen safe section 420.

The feed roller 13 has a knurl,
In the outer peripheral portion of the feed roller 13, a groove 22 having a rectangular cross section in a direction perpendicular to the rotation axis is formed at regular intervals in parallel with the rotation axis. A gear 23 (indicated by a dotted line in FIG. 2) is mounted on the shaft 21 of the feed roller 13 on the opposite side in FIG. 2, and a pulley 24 is provided on the near side in FIG. 2 (the left side in FIG. 2 in the feeding direction). Is attached. A flat belt 25 (see FIG. 1) is stretched over the pulley 24, and the flat belt 25 further includes an outer wall 42 of the safe section 420.
2 is mounted on a pulley 27 (see FIG. 1) of an output shaft 26A of a drive motor 26 as a drive unit attached to the drive motor 26. Note that the shaft 18 and the shaft 21 are arranged in parallel.

Feed roller 13 and timing roller 1
Between the two large gears 28 coaxially arranged in parallel with each other
A and an intermediate gear 28 formed by a small gear 28B (indicated by a two-dot chain line in FIG. 2).
In addition, the small gear 28B meshes with the gear 20. Therefore, the rotation of the drive motor 26 is transmitted to the feed roller 13 via the flat belt 25, and transmitted from the feed roller 13 to the timing roller 12 via the intermediate gear 28.

The center of rotation of the feed roller 13 is set at a position slightly shifted to the feeding side from a plane passing through the center line of rotation of the feed roller 13 and perpendicular to the 1,000-yen bill, and has a predetermined gap with the outer peripheral surface of the feed roller 13. A gap roller 14 is installed. The gap roller 14 is composed of two small rollers 14A, 14 coaxially arranged in parallel and parallel.
A is included. The gap roller 14 is cantilevered from the outer wall 422 on the near side in FIG. 2 of the safe section 420 and is mounted on the shaft 29 that is perpendicular to the outer wall 422 and horizontally protrudes. One small roller 14A is located axially intermediate between the small roller 13A at one end and the intermediate small roller 13A. The other small roller 14A is located axially intermediate between the middle small roller 13A and the other small roller 13A. Note that the shaft 29 is disposed parallel to the shafts 21 and 18. In addition, a gap exists between the feed roller 13 and the gap roller 14, and the value is set to be larger than the bill thickness and smaller than twice the bill thickness.

The payout side end wall 30 of the safe section 420 of the 1000 yen safe 400 is located near a plane passing through the rotation center line of the feed roller 13 and perpendicular to the 1000 yen bill. As shown in FIG. 5, the height of the upper end portion of the feeding side end wall 30 is located at a position slightly higher than the height of the lowermost portion of the gap roller 14. One end of each of the two rubber plates 15 is fixed to the central portion of the upper end portion of the feeding side end wall 30 and is mounted upright. The thickness of the rubber plate 15 depends on the end wall 3 on the feeding side.
The thickness is substantially equal to 0, and the rubber plate 15 overlaps a virtual surface extending the feed-out end wall 30 upward. In addition, rubber plate 1
5 are arranged at intervals substantially equal to the width of the gap roller 14.

Two guides 3 are provided on the upper side of the end wall 30 on the delivery side.
3 and 33 are mounted adjacent to the side surface of the gap roller 14 at intervals substantially equal to the width of the gap roller 14. As shown in FIG. 2, the guide 33 includes a vertical end wall 33A, a central portion 33B, and an end.
A recess (not shown) is formed in the guide 33, and the width and depth of the recess are equal to the width and thickness of the rubber plate 15, respectively. The surface of the safe section 420 other than the concave portion and the rubber plate 15
The surface of the safe section 420 side is flush.

A curved central portion 33B is connected to a vertical end wall 33A which forms a vertical plane of the guide 33. The central portion 33B is a gap roller when viewed from the rotation center line direction of the gap roller 14. 14 is formed substantially along the outer peripheral surface. That is, the radius of the curved central portion 33 </ b> B is substantially equal to the radius of the outer peripheral surface of the gap roller 14. At the tip of the central portion 33B, a planar end of the guide 33 inclined slightly upward from the horizontal plane is connected.

When the rubber plate 15 is pushed and bent in the extending direction,
The guide 33 comes into close contact with a part of a portion corresponding to the vertical end wall 33A and the central portion 33B of the concave portion so as to be wound around. The portion of the rubber plate 15 which is in close contact with the portion corresponding to the vertical end wall 33A of the recess forms the extended wall surface of the feed-out end wall 30 as described above, and is in close contact with the portion corresponding to the central portion 33B of the recess. 15 safe section 420 of rubber plate wrapped around
The side surface portion is along the outer peripheral portion of the gap roller in the figure. The length of the rubber plate 15 is set so that the other end contacts the feed roller 13 and can contact the feed roller 13 within a range of about ± 20 degrees from the lowest point.

Next, with reference to FIG. 2, the operation of the bill feeding mechanism 11 will be described with reference to the Senyin safe 400 as an example. The operation of the bill feeding mechanism 11 of the 5,000 yen safe 500 is the same as that of the 1,000 yen safe 400.

The safe section 42 of the 1,000 yen safe 400 (see FIG. 1)
Immediately before the 1000-yen bills accumulated in 0 are fed out from the safe section 420, the 1000-yen bills are in contact with a bill-dropper 433 described later. The process until the 1,000-yen bill contacts the bill-dropper 433 will be described later. When the timing roller 12 rotates to pay out the 1,000-yen bill, the outer peripheral portion 17 protruding from the opening 433A of the bill-dropping plate 433 comes into contact with the surface of the first 1,000-yen bill,
The first 1000-yen bill is fed in the feeding direction by the frictional force acting on the outer peripheral portion 17 and the contact portion. The second 1,000-yen bill also moves in the feeding direction due to the frictional force acting between the first and second bills. Similarly, the third and subsequent 1000-yen bills also move in the pay-out direction due to the repetitive output caused by the frictional force exerted by the upper 1000-yen bill.

Therefore, among the stacked 1,000-yen bills, the 1000-yen bills from the uppermost layer to the several layers move in the feeding direction and hit the rubber plate 15, and the rubber plate 15 comes into contact with the bending guide 33 in the feeding direction. During the course in which the rubber plate 15 bends, the first 1,000-yen bill contacts the feed roller 13 and the feed roller 13
Is also paid out. When the first 1000-yen bill is fed slightly further after contacting the feed roller 13, the 1000-yen bill is separated from the timing roller 12 and is fed only by the feed roller 13.

The pressing force acting on the first 1000-yen bill from the feed roller 13 is Fp, and the repetition output is Ff. Further, the friction coefficient between the 1,000 yen bill and μ is defined as μ ′ (μ <μ ′). The feeding output from the feed roller 13 acts in the feeding direction of the first 1,000-yen bill.
Here, the coefficient of friction between the feed roller 13 and the 1000-yen bill is configured to be much larger than the friction coefficient between the 1000-yen bills, so that the first 1000-yen bill is fed.

The force acting in the dispensing direction from the first 1,000-yen bill to the second 1,000-yen bill in the dispensing direction due to friction between the 1,000-yen bills is μFp, and the second 1,000-yen bill is unfolded. If not, μFp is balanced with the resistance in the anti-pull-out direction generated by friction between the second 1,000-yen bill and the rubber plate 15. The maximum resistance in the anti-pull-out direction generated by friction between the second 1,000-yen bill and the rubber plate 15 is μ'Fp,
Comparing these forces, μFp <μ′Fp.

Therefore, the second 1,000-yen bill is not fed out, and only the first 1,000-yen bill is fed. When the first 1,000-yen bill is fed out by a predetermined distance, the feed roller 13
Is in contact with the first 1,000-yen bill, the first 1,000-yen bill is transported by the fourth transport section 700 (see FIG. 1) on the downstream side. The above-mentioned coefficient of friction between the 1,000-yen bill and the rubber plate 15 is referred to. If the coefficient of friction is changed by performing surface treatment on the rubber plate 15, this means the coefficient of friction after the treatment.

After the first 1,000-yen bill has been paid out, the feed roller 13 rotates in the reverse direction (rotates clockwise in the drawing). At this time, the rubber plate 15 is returned from the vertical position to a position rotated about 20 degrees from the vertical position by the groove 22 formed on the outer peripheral portion of the feed roller 13 and is bent in the anti-feeding direction. Therefore, the stacked 1000-yen bill is returned to a position away from the gap roller 14. Therefore, the new first-thousand-yen bill is fed out at the next interval in the same manner as described above. Therefore, the 1000 yen bill is reliably fed out one by one.

Next, with reference to FIG. 1, the structure and operation of the bill processing apparatus 1 using the above-described bill feeding mechanism 11 will be briefly described. The bill processing device 1 has an insertion slot 7 into which a bill is inserted.
A bill identification device 100 is provided that identifies 0, the authenticity of inserted bills, the type of bills, passes only acceptable bills, and rejects unacceptable bills and returns them. The accepted bill is transported by the first transport unit 200, and only the 1,000-yen bill is sorted by the first sorting unit 220 and transported to the 1,000-yen safe 400. Other bills pass through the first sorting unit 220 as they are, and are transported to the second sorting unit 320 by the second transport unit 240.

The 5,000-yen bill is sorted by the second sorting unit 320 and is conveyed to the 5,000-yen safe 500. The 10,000-yen bill passes through the second sorting unit 320 as it is, is transported by the third transport unit 260, is sorted by the third sorting unit 340, and is transported to the 10,000-yen safe 600.

The 1,000-yen bill carried into the 1,000-yen safe 400 is held and supported on two support members 431 arranged near each outer wall 422 (see FIG. 4) of the safe section 420.
At this time, the support member 431 is at the lowest position, and the 1000-yen bills already stored and accumulated on the mounting table 432 urged upward by a coil spring (not shown) are placed on the mounting table 4.
32 together with the biasing force against the mounting table 432.

Thereafter, when storing a 1,000-yen bill, the support member 431 is raised, and the 1,000 yen on the support
33, and the 1,000 yen cannot rise any more. On the other hand, since the support material 431 further rises, the 1,000-yen bill gradually falls off from the support material 431 and is placed on the mounting table 432 on the 1,000-yen bill already stored. After that, the support member 431 reaching the uppermost position descends and contacts the newly placed 1,000-yen bill, overcoming the biasing force of the coil spring described above,
The 1000-yen bill and the mounting table 432 on which it is to be placed are pushed down to reach the lowest position. At this time, the support member 431 secures a space thereon again, and is ready to receive and support a newly imported 1000-yen bill.

The 5,000-yen bill carried into the 5,000-yen safe 500 also has a 5,000-yen safe 5 in the same manner as in the case of the 1,000-yen safe 400.
00 is stored.

The 10,000-yen bill carried into the 10,000-yen safe 600 is placed on two fixed support members 631 arranged near the side walls (not shown) of each of the 10,000-yen safe 600. It is reserved and supported by. The support member 631 is placed on the mounting table 621 urged upward by a coil spring (not shown).
Place the 10,000 yen bill already stored and accumulated
Pushed down with 1 to oppose the aforementioned biasing force.

When a transaction is started and a 10,000-yen bill is stored, the bill dropping plate 641 descends, abuts against the 10,000-yen bill on the support 631, and further, the 10,000-yen bill on the support 631 is removed. Push down to drop from support 631. The dropped 10,000-yen bill overlaps the 10,000-yen bill already accumulated on the mounting table 621. The bill dropper 641 pushes the mounting table 621 further down with the 10,000-yen bill, reaches the lowermost position, rises again, reaches the uppermost position on the original support member 631, and stands still. A space is secured on the support material 631, and preparation for holding a new 10,000-yen bill thereon is completed.

When the transaction is started and it is necessary to pay out the bills, the necessary 1,000-yen bills and 5,000-yen bills out of the stored 1,000-yen bills and 5,000-yen bills are replaced with 5,000-yen bills and 1,000-yen bills. The bills are fed by the bill feeding mechanism 11 in the order of the bills, and are conveyed to the 10,000 yen safe 600 by the fourth conveyance unit 700. The 5,000-yen bill and the 1,000-yen bill conveyed to the 10,000-yen safe 600 are held on the support material 631, and are collectively returned by the collective return means 800 to the return port 81.
Returned to 0.

If the transaction is canceled after the insertion of the bill, the 1,000-yen bill is placed on the support 531, the 5,000-yen bill is placed on the support 531, and the 10,000-yen bill is placed on the support 631. On hold. The 5,000-yen bill and the 1,000-yen bill are stored once, and then the bill feeding mechanism 1 is arranged in the order of the 5,000-yen bill and the 1,000-yen bill.
1 and is transported to the 10,000 yen safe 600 by the fourth transport unit 700. The 5,000-yen bill and the 1,000-yen bill conveyed to the 10,000-yen safe 600 are put on top of the 10,000-yen bill on the support material 631 and held, and are collectively returned to the return port 810 by the collective return means 800. You.
