[Detailed Description of the Invention] [Technical Field of the Invention] The present invention provides a paper sheet that is capable of ejecting paper sheets accumulated in the accumulation chamber to the outside of the accumulation chamber by opening a shutter forming the bottom of the accumulation chamber. This invention relates to improvement of a leaf accumulating device.

[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,
Separately stack 1,000 yen bills and 500 yen bills in four stacking rooms, and
When the classification and aggregation of 0 tons is completed, the discharge ports of each of these accumulation chambers are opened, and the lot is stored in the storage corresponding to each accumulation chamber, and then the next lot is processed.

However, in conventional stacking devices, the opening and closing speed of the shutter forming the bottom of the stacking chamber is relatively slow, so the paper sheets discharged outside the stacking chamber are slanted and the discharge posture is disturbed.
There is a problem that the items may not be collected in an orderly manner in the storage area, which may be an obstacle to post-processing.

[Purpose of the invention]

The present invention has been made based on the above-mentioned circumstances, and an object of the present invention is to stack paper sheets so that the paper sheets in the stacking chamber can be discharged in an orderly manner, thereby eliminating the inconvenience caused by disordered discharge posture. The aim is to provide equipment.

[Summary of the invention]

In order to achieve this object, the present invention sets the opening speed of the shutter to be faster than the shutter closing speed, so that the accumulated paper sheets can be ejected in an orderly manner.

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

FIG. 1 is a schematic perspective view of a banknote sorting and tallying machine to which an embodiment of the stacking device of the present invention is applied, and FIG. 2 is a front view of the entire machine. In the figure, 1 is a main body, and a display operation device 2 is provided on the upper part of the main body 1, and a bill slot 3 is provided.
and a banknote reject opening 4 are provided. and,
A bill ejecting device 5 is provided in the main body 1 facing the bill inlet 3, and the bills P placed in the inlet 3 are sequentially taken out one by one into the take-in conveyance path 6. It is now possible to send it in.

Then, the taken-out banknote P passes through a discriminating section 7 that determines the denomination, authenticity, correctness, front and back, etc. of the banknote while being conveyed through the take-in conveyance path 6. Banknotes P determined to be abnormal by the discrimination section 7 are sent to the banknote rejection port 4, and normal banknotes P are guided to the left in the figure by the distribution date 8. Further, the banknotes P determined as fronts by the discriminator 7 are guided to the first conveyance path 9, and the banknotes P determined as backs are guided to the second conveyance path, that is, front and back sides, by the second sorting gate 10. The paper is guided to the reversing conveyance device 1 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 the banknotes P conveyed at a constant pitch are
Even if they are sorted by the second sorting gate 10 and pass through separate conveyance paths 9 and 11, when they merge at the merging section 12, they are conveyed at a constant pitch without colliding or pitch clogging. It is supposed to be done. Furthermore, the banknotes P, whose front and back sides are aligned, are conveyed to a sorting conveyance path 13 as a sorting section connected to the merging section 12, and are sorted by denomination. Further, below the sorting conveyance path 13, stacking devices 14g, 14b, 14e, and 14d stack banknotes sorted by denomination in a sequentially stacked state.

, 15d is provided with a shutter device 16. Furthermore, in order to ensure storage in each storage compartment 15 & ~ J5d, a pushing device R1 that pushes the banknotes P...
7 is provided.

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

In FIG. 3, 20 is a 5-conveying path twisted 180' (this twist).As shown in FIG. It is formed by stretching two rows (hereinafter referred to as twist belts) in a figure-eight shape via a plurality of rows 222a to 221. Further, as shown in FIG. 5, flat plate-shaped twist guide bodies 23m, 23b, 23e, and 23d are arranged along both sides of the K twist conveyance path 20. These flat plate-like twist] guide bodies are supported by pillars (not shown), 23m, 23b, 23e, 23d.
The id bodies also form a pair, and are twisted while keeping the gap a shown in FIG. 6(a) in accordance with the twist of the twist belt 2. These twisted guide bodies 23 to 23e are located on both sides of the twisted belt 21, and are continuous from the entrance to the exit of the twisted conveyance path 20, so they can be folded into four, half-folded,
In addition, it is effective for soft banknotes P that have weak elasticity, and its purpose is to fold the banknotes P into four pieces. The result is as shown in Figure 6←). In order to prevent this and ensure stable reversal conveyance, it is necessary to firmly pack up both ends and guide the guide bodies 23*, 23b.
The pair 23c and 23d play this role. Further, in the figure, reference numeral 24 denotes an air roller, which is located at the center of the folding belt 21 and provides a clamping force for the banknote P. This is because the twisting belt 2 tries to restore itself, so no conveying force can be expected on the twisting conveyance path 20.

Furthermore, when the banknote P is conveyed while being reversed on the twist conveyance path 20, it is conveyed in the shape shown in FIG. This will cause a collision. Rollers 24 and 25 located on the conveyance path 20
It is necessary to make it the same as or smaller than 10 width.

(Refer to FIG. 6 (a) ←)) Since the banknotes P are forcibly twisted in the twist conveyance path 20, they tend to become curly, and the face banknotes P are conveyed as they are from the first conveyance path 9. When combined with other substances, it is easy to cause a jam. Therefore, a flat conveyance path, such as a horizontal conveyance path 26, is required to correct the curl after reversal. As shown at L in FIG. 5, they are arranged to merge after correction in a horizontal conveyance path 26 for at least one banknote.

The twist belt 21 is driven by a drive belt 27 from the motor 18 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° 22d, and constitutes a second conveyance path (front-back reversal conveyance device) 1 and a sectional conveyance path 13, which are configured to rotate. Further, the drive belt 32 is wound around the drive rollers 22d, 33.degree. 34, so that the conveyance belts constituting the first conveyance path 9 and the reject conveyance path 35 rotate.

Further, among the rollers 22m to 22f, only the roller 22d provided on the exit side of the twisted conveyance path 20 serves as a driving roller and forms the twisted conveyance path 20 and the horizontal conveyance path 26 for the belt 21. The portion is on the tension side to prevent uneven speed, slack, deviation, etc. of the belt 21, and to reliably turn the paper sheets P inside out without causing skews, jams, etc. In this way motor 2
7, all conveyance systems rotate at the same speed. Furthermore, although the conveyance distances of the first conveyance path 9 and the second conveyance path (front-side reversing conveyance device) 1 are set to be the same, the transit times may not necessarily be the same due to belt and roller slips, etc. Not exclusively. By moving the roller 36 for correcting the passage time of the bird helmet 1 on the conveyance path 9 as shown by the broken line in FIG. It looks like this.

In this way, the pitch of the banknotes at the confluence 12 of the 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 determined by the second vibration. The υ minute is completely the same as the bill pitch in front of the gate 10, and the arrangement is such that the order of the bills is not changed, the bills do not collide, and the timing of the operations is not impaired.

The banknotes P conveyed by the belt in the take-in conveyance path 6 are discriminated by the discriminator 7, and the banknotes P which are determined to be genuine or false or abnormal are transferred to the first sorting gate 8 as genuine banknotes. Images are taken separately in the transport section. Then, even if the banknotes P are normal, the banknotes P that are determined to be fronts are guided to the first transport path 9, and the banknotes P that are determined to be backs are sorted out by the dirt IO and then sorted into 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 side is reversely conveyed by the twisting belt 21, but both ends of the banknote P are connected to the guide pairs 23h to 23.
d, the genuine banknote P is conveyed 180 degrees inverted while being guided by the Quazzo to correct it to the front banknote P. After correcting the curl in the horizontal conveyance path 26, the above-mentioned At the merging section 12, the front banknotes P sent out from the first conveyance path 9 are merged and conveyed without the pitch between the banknotes being out of order. 10- Oh, the same effect can be obtained even if the twist guide bodies 23a to 23d described above are replaced from flat plate-like ones to twist guides 37 and 37d that are wire-like and have a round cross section as shown in FIGS. 7 and 8. do.

That is, since the banknote P is conveyed by rotating the twist conveyance path 20 by 180 degrees, the twist conveyance path 20 is rotated by 180 degrees, so the twist conveyance path 20 is rotated by 180 degrees.
As shown in , the lead angle θ (-θ=2b-) that can be calculated from the width of guiding the outer periphery of the cylinder 20' and the reversal conveyance distance a.
Even if the wire-like twist guide bodies J7a to 37d, which are wound in a helical shape at an angle of .

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. The pipes for dividing into each of the collecting devices 14h to 14d are constructed 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 guide rollers 40, and a substantially horizontal lower surface of the conveyor belt 4. A part of the banknote P is in contact with the mutually opposing surface with a plurality of conveyor belts 43 stretched respectively through idle rollers 42.
is designed to be held and conveyed in the direction of the arrow. Also,
At positions corresponding to the first to third accumulation devices 14h to 14e, sorting darts 44m, 44b, and 44e, which can be rotated by a rotary lens (not shown), are arranged, and the darts try to move straight in the direction of the arrow. Banknotes P... can be guided to the stacking devices 14a to 14c as appropriate. In addition, the distribution dirt is 44m, 44. The banknotes P sorted by b and 44e are transferred to a mutually opposing portion between a substantially vertical portion of the conveyor belt 43 and a conveyor belt 46 stretched through guide rollers 45 and 45 so that a portion of the conveyor belt 46 is in contact with this approximately vertical portion. The banknotes P guided to the fourth stacking device 14rl are transported to the first to third stacking devices 14a to 14c via the transport path 47 formed by the transport belt. 41 and the conveyor belt 43 at the right end in FIG. The segmented conveyance path 13 configured in this manner sequentially transports the banknotes P sent out from the merging section 12 to the conveyor belts 41, 43, and so on.
It is conveyed in a short direction while being held between the two. As a result of the denomination discrimination by the discriminating section 7, if the denomination of the conveyed banknote P is, for example, a 100 yen banknote, the rotary lenoid (not shown) is excited and the sorting gate 44a is opened as shown in FIG. The banknote P is rotated upward from the state shown in FIG. 11, that is, to the solid line position in FIG.
It is guided downward by m and fed into the conveyance path 47. After this, the rotary solenoid (not shown) is demagnetized and the state shown in FIG.
The state is returned to the state indicated by the two-dot chain line in Figure 1). In the case of a 5,000 yen bill, the sorting gate 44b operates in the same manner as described above, and in the case of a 1,000 yen bill, the sorting gate 44e 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 categorizing conveyance path 13 without being sorted along the way. The banknotes P... guided to the sorting conveyance path 13 are sorted into denominations in this way. Next, banknotes P classified into denominations in this way...
The accumulation devices 14m, 14b, 14e, 1
4d will be explained based on FIGS. 10, 11, and 12.

A first integrating device 14a is provided below the dividing gate 44a, and a second integrating device 14b is provided below the dividing gate 44b.

A third accumulating device 14c1 provided below the sorting gate 44a and a fourth accumulating device 14d provided below the terminal end of the sorting conveyance path 13 have substantially the same configuration, After being sorted by the sorting darts 44a to 44c, the banknotes P... are carried out through the conveyance path 47...
・Alternatively, it is composed of an impeller mechanism 50 for stacking the banknotes P directly carried out from the terminal end of the divided conveyance path 13 in the surface direction, and a stacking chamber 51 for guiding and stacking the banknotes along the sides. There is. The specific configuration of the impeller mechanism 14-50 and the accumulation chamber 51 is shown in FIGS. 11 and 12.
As shown in the figure, a support shaft 52 is supported by a bearing 54 provided on a side frame 53, and a driven gear 55 is fitted onto the support shaft 52. The support shaft 4 of the guide roller 42 is mounted on the side frame 53.
2a is attached, and an intermediate gear mechanism 5 is provided between the drive gear 56 fitted on the guide roller 42 and the driven gear 55.
7 is provided, and when the guide roller 42 is rotated by the rotation of the drive belt 29, the rotational force is sequentially transmitted to the drive gear 56, intermediate gear mechanism 57, and driven gear 55, and is attached to the intermediate portion of the support shaft 52. The attached impeller 58 is configured to rotate. The impeller 58 includes a ring-shaped impeller main body 58&, and a plurality of blade plates 58b whose proximal ends protrude radially from the support shaft 52 and are bent in a predetermined direction. It is composed of... Also, each feather board 5

It is installed outside of Pb.

Although not shown, 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, it is possible to avoid folds when the bill is large in size. If a 10,000 yen bill is used as a standard, folding can naturally be avoided even for low-denomination bills. By arranging the impellers 58, 58 in this manner, it is possible to reliably prevent the banknotes from jamming in the impellers 58, 58 even if the banknotes P have some creases. Moreover, each of the accumulation chambers 51... has the wing plate 58b as shown in FIG.

．． 60, the contact area with the banknotes P can be reduced, so that the banknotes P can be dropped smoothly.
The static electricity generated on the banknote P during contact with the banknote 6 is effectively removed through the linear convex portions 59b..., 6ob... of the engaged metal plate, so that there is no abnormality in the banknote P falling due to the influence of static electricity. And the uneven accumulation can be completely removed. In addition, each of the wall plates 59 and 60 has an embossed flange,
It is also possible to replace it with one constructed by conductive plating on the surface of the plate.

The operation of the thus configured integration devices 14h to 14d will be explained. The banknotes P17-, which are sorted into various denominations 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. Kototonashi,
For example, if 10,000 yen banknotes are transported to the first stacking device 14m, the above classification? "-) 44a toward the impeller 58.58 rotating in the direction of arrow E shown in FIG.

At this time, the impellers 5FI and 5B are rotated at a circumferential speed that is approximately 1/4 of the banknote conveyance speed in the divided conveyance path 13, and the blade plates 58b of the impellers 58 and 58.

A banknote P is inserted between the blades 58b and conveyed while being sandwiched between the blade plate 511b and the blade wheel body 58a. Then, as the impellers 58 and 58 rotate, the banknotes P are transferred, and the notch 59g of the left side wall plate 59 of the accumulation chamber 51,

It is supported so as to be able to reciprocate freely via 71...

The first partition plate 65a is bent to form a protrusion 72.72 protruding from the upper surface, and
Also in the second partition plate 65b, the first partition plate 65m
Similarly, protrusions 73.73 are formed, and the protrusions 73.73 are arranged one above the other so as to overlap and fit with the protrusions 72.72. Further, the protruding portions 72.72 are nested with the left side wall plate 59 of the accumulation chamber 5 (see FIG. 14(a)), and the protruding portions 73 are similarly nested with the left side wall plate 60 of the accumulation chamber 5.
Both are nested, and these are the first partition plates 65a.
and the second partition plate 65b move relatively back and forth, and the partition plate 6
When the banknotes P placed on the 5th and 65b are dropped, the banknotes P are prevented from entering the gaps 74 between the side walls 59 and 60 and the partition plates 65m and 65b. The specific configuration of the drive unit 66 is not shown in the figure, as it is attached to the main body 1! Shaft 75 stuck to racket

8, a link 79 connecting to the second partition plate 65b, and a direction in which each partition plate 65a, 65b is opened (arrow G in FIG.
G, direction), that is, each partition plate 65a.

The banknotes P... placed on the storage area 15a~
A spring 80 is hooked thereon to bias it in the direction of dropping it to isa. Also, one end of the arm 76 has a bent portion 76.
a is formed, and a motor 8 is attached to this bent portion 76m.
A roller 83 rotatably attached to a rotating arm 82 fixed to and rotating on a drive shaft 1 is configured to be able to roll into contact with the bent portion 76h against the force of the spring 80. is in contact with. That is, the partition plate 65m,
65b is closed, and banknotes P are placed in the accumulation chamber 51.

In addition, since the arm 76 and the rotating arm 82 fixed on the axis of the motor 81 are almost at right angles to form a dead center, it is possible to prevent the partition plates 65h and 65b from being manually operated. 15a to 15d has the unique effect of ensuring the safety of the banknotes P... stored in them.

Next, the operation of the shutter device 16 will be explained. When a predetermined number of sheets are placed in the accumulation chamber 51, the motor 81 is energized and the drive shaft is rotated for a predetermined period of time.
2 is stopped at the position shown by the two-dot chain line in FIG. When the tip roller 83 of the rotating arm 82 comes into contact with the bent portion 76m of the arm 76, the arm 76 is instantly rotated by the force of the spring 80, and the first partition plate 6
5 & is in the direction of Gl in the figure, the second partition plate 65b is G,
The banknotes P, which are relatively moved in the direction of the bottom of each accumulation chamber 51, that is, the discharge port 51a, are simultaneously opened and placed
... are dropped into the storages 15a to 15d. In other words, it moves left and right in the same way as Daruma Otoshi and falls horizontally.

Further, 84 is the bottom end of the arm 76. Also 22
- 85 is a detector which detects that each partition plate 65*, 65b is opened. Moreover, 86 is each partition plate 65h, 65b
This is a stop detector that detects when the is closed. Next, regarding the method of closing the partition plates 65 & 65b, when the operation of the pushing device 17 (described later) is completed and a predetermined detection is made, the motor 8 is reenergized and the rotating arm 82 is moved by the arrow shown in the figure. When it rotates in the input direction and rotates by a predetermined amount, it comes into contact with the bent portion 76m of the arm 76, and the arm 76 is rotated against the biasing force of the spring 80, and is detected by the stop detector 86. The rotation of the motor 81 is stopped. In such a shutter device 16, there are a plurality of stacking units 5 from the first stacking device 14m to the fourth stacking device 14d.
65t of four first partition plates connected to each other
h and four second partition plates 65b connected to each other, and a drive unit 66 that drives both partition plates 65h and 65b relative to each other at the same time. Since banknotes P... can be stored at the same time, the cost can be reduced to about 1/4 compared to the conventional system in which one shutter device is used for one accumulation chamber 51. Since there is only one shutter device, the failure rate is reduced to 1/4, etc., which has a cumulative effect.

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 65t, 65b, and according to this configuration, the spring By selecting 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 configuration of the pushing device 17 is shown in FIGS. 13, 15, and 16, and includes a side frame 53 fixed to the main body 1 and a vertically movable device whose one end is fixed to the side frame 53.

The frame 91 is configured to be vertically movable (in the direction of arrow B in FIG. 16). The frame 91 is driven by the main body 1.
A motor 94 and a bearing box 95 are attached to a bracket 93 fixed to the bracket 93.

A bevel gear 96 is attached to the output shaft of the motor 94, and a bevel gear 98 is attached to one end of a shaft 97 fitted in a bearing box 95. The output from the motor 94 is transmitted to a shaft 97 attached to the shaft 97 at 25-. An arm 100 is fixed to the other end of the shaft 97, and a link 102 is rotatably attached via the arm 1oo and a bottle 101.

Further, a fixing pin 103 is fixed to the frame 9, and the link 102 is fitted onto the fixing pin 103 to connect the motor 9.
The rotational force of 4 is converted into vertical motion and transmitted to the frame 9. The operation of the pushing device 17 will be explained. Banknote groups P... are stored in each of the accumulation chambers 51...
When a predetermined number of banknotes are accumulated, the shutter device 16 is activated and the banknote groups P... are freely dropped into the storage boxes 15a to 15d. Here, when the shutter device 16 is detected by the detector 85, the movable body moving means 89 operates. That is, the motor 94 is energized and the bevel gear 96 is turned on.
Power is transmitted to the bevel gear 98, and the arm 95 rotates in the direction of arrow C as shown in FIG. 15 via the shaft 97. A link 102 is attached to one end of the arm 95 via a pin 101, and a frame 9126 is attached to this link 102 via a fixed pin 103, so that when the arm 100 rotates in the direction of arrow A, it is attached to the frame 91. pushed member 92
... moves downward as shown in Fig. 15, and the storage compartment 1

It is designed to be stored by pushing it in. Further, when the arm 100 rotates 180 degrees, the frame 91 reaches the bottom dead center, which is detected by the detector 105, and the pushing operation is completed. That is, the mechanism is such that the frame 91 moves back and forth once by one rotation of the arm 100. 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, as shown in FIG. 13, each wall plate 59.6 of each accumulation chamber 51...
0, there are 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 cutout portions 92m so that the bills 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, Unlike the conventional configuration, which constitutes an independent pushing device for the first to fourth accumulation chambers and storage, it is possible to simultaneously operate the first to fourth accumulation chambers and storage in one operation. Since it is configured to be pushed in all at once, only one drive device is required, and the number of parts is small and the cost is 1/2.
It can be lowered to about 4, which has a great effect. The display/operation device 2 is configured as shown in FIG.
15, a card insertion slot 116, and a slip issuing slot 117. The mode designation switch 111 is used to designate a processing mode such as classification, counting, or counting classification. The above operation key group 114 is the denomination specification key 11
4e, an operator number key 114g, and a total key 114h. The display unit 115 also includes a display 115m that displays the number of coins for each denomination,
It is constituted by a display 115b that displays the number of sheets collected in each stacking section, a display 115a that displays the % total amount, and a display 115e that displays the total number of sheets. The operation of the display operation device 20 configured in this way will be explained.

For example, by setting the mode designation switch 111 to counting classification, the control section (not shown) is 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 1.
13, input the processing number 114C, input the operator number key 114d, and input the operator's operator number key using the numeric keypad 113.The account number, processing number and operator number input using the numeric keypad 113 are Display 115e
29- is particularly confirmed. Then, in a standing position, the banknotes P deposited in the ordinary deposit are thrown into the slot 3 at once, regardless of whether they are front or back, and the start key 114f is turned on.

Then, the banknote P is transferred to the ejecting device 5, the conveyance path 6, the discriminator 7,
Further, the banknotes that are determined to be front banknotes by the discrimination unit 7 are the first banknotes.
The banknotes that are determined to be reverse banknotes are transferred to the second transport path 1.
1, corrected to front banknotes, and merged into the confluence section 12,
Sorting conveyance path 13, accumulating device 14, shutter device 16,
It is stored in the storage 15 via the pushing device 17, and the discriminating section ? The number of banknotes for each denomination determined by
5b, and the total amount deposited is further displayed on the display 115c. Thereafter, when the operator inputs the print key 115@, the control unit (not shown) prints out the account number, disposal number, operator number, number of coins with denomination, amount, and total number and amount using a printer (not shown). urge Further, time deposits, -30=, and savings deposits operate in the same manner as described above, and the number of coins for each denomination and the total amount are processed together with the account number processing number and the credit rating number. Although a crank mechanism using a pair of bevel gears 96.98 is used for pushing and @ movement has been described, other mechanisms are also possible. For example, the same effect can be obtained by using a Sol screw at one end of the frame 9 for reciprocating movement, and the same effect can also be obtained by replacing it with various mechanisms such as a chain or belt transmission. Needless to say.

In addition, 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.

In other words, although the explanation has been given of a device that is applied to a banknote sorting and tallying machine to accumulate banknotes, it may also be used to accumulate paper sheets other than banknotes. Any device may be used as long as it discharges the paper sheets accumulated in the accumulation chamber to the outside of the accumulation chamber.

Moreover, although the description has been given of a device having a plurality of accumulation chambers and in which the shutters are opened and closed all at once, it is needless to say that the invention is not limited to this.

Furthermore, although the paper sheets in the stacking chamber are stored in the storage compartment, the paper sheets may be transferred onto the conveyance path, for example.

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 paper sheet stacking device that allows paper sheets stacked inside the stacking chamber to be discharged to the outside of the stacking chamber by opening the shutter forming the bottom of the stacking chamber. In the paper sheet stacking device, the opening speed of the shutter is set faster than the closing speed. Therefore, the accumulated paper sheets are ejected in an orderly manner in a drop-down manner, and there is an effect that inconveniences due to disturbances in the ejection posture can be reliably prevented.
