Description

The present invention relates to a paper sheet storage device and a paper sheet processing device capable of storing paper sheets.

A paper sheet processing device is a device that processes paper sheets. For example, the paper sheet processing device is a banknote processing device that processes banknotes. The banknote processing device includes a deposit port for depositing banknotes, a withdrawal port for withdrawing banknotes, a conveyance path for transporting banknotes, an identification unit for identifying the type of banknotes, such as a denomination, and a sorting unit for distributing banknotes by denomination. The banknote storage device includes a banknote storage device that stores and dispenses banknotes sorted by a division and a distribution unit.

Such a banknote processing apparatus identifies the denomination of banknotes deposited through a deposit port using an identification unit disposed midway along a conveyance path. The banknotes whose denominations have been identified are sorted by denomination by the sorting section and stored in the banknote storage device for each denomination. When a bill withdrawal instruction is given, the bill processing device discharges the instructed bill from the bill storage device, transports it, and dispenses the bill from the withdrawal port. For example, banknote handling devices are used in money exchange machines and change machines.

The specification of International Publication No. 2011/036783 describes a paper sheet storage and dispensing device that stores and discharges banknotes. This paper sheet storage/dispensing device is equipped with a roller that wraps the banknote together with the tape, and a reel that wraps the portion of the tape that is not wound around the roller. Hereinafter, such a roller may be referred to as a drum. Further, the paper sheet storage and dispensing device is equipped with a motor that drives rollers and reels. The roller is connected to and driven by a shaft protruding from one end of the motor via a transmission mechanism. The reel is connected to a shaft protruding from the other end of the motor via a transmission mechanism, and is driven. Further, a part of the motor and a transmission mechanism that transmits the driving force from the motor to the roller are arranged inside the roller.

When the motor is rotated in the first direction, the roller rotates in the direction in which the tape is wound, and the tape is unwound from the reel. At this time, the banknotes are sandwiched between tapes, wound around rollers, and stored in the paper sheet storage/dispensing device. When the motor is rotated in the other direction, the reel rotates in the direction in which the tape is wound, and the tape is rewound from the roller. At this time, the banknote is taken out from between the tapes and discharged from the paper sheet storage/dispensing device.

International Publication 2011/036783

There is a demand for miniaturization of paper sheet storage devices, and parts of the drive mechanism are sometimes stored inside the reel or roller. In conventional devices, part of the motor and part of the drive mechanism are housed inside the roller, but shafts protrude from both ends of the motor, and the drive mechanism is connected to each shaft. A drive mechanism is also arranged outside the roller. For example, a one-way clutch is disposed between the rotation shaft of the reel and a drive mechanism that drives the rotation shaft. Conventional devices have a configuration in which the drive mechanism is placed on both sides of the motor, which poses the problem of making the device wide.

The paper sheet storage device of the present invention includes a drum that sandwiches paper sheets between tapes and winds up and unwinds the tape and the paper sheets together, and a drum that winds up and unwinds only the tape. a reel, a motor disposed at least partially inside the drum, and a base for fixing the motor; when the drum rewinds the tape, the reel rewinds the tape; When the drum rewinds the tape, the reel rewinds the tape and, based on the rotational direction of the motor, either rewinds the paper sheets conveyed from the outside onto the drum or rewinds the drum. In the paper sheet storage device for discharging the paper sheets to the outside, the motor is connected to a rotating shaft protruding from one end of the motor, and changes the number of rotations of the rotating shaft to a first predetermined number of rotations. a first conversion mechanism that outputs rotation to the transmission shaft; and a first conversion mechanism that is disposed on a drive force transmission path from the transmission shaft to the drum and transmits rotation in one direction of the transmission shaft and does not transmit rotation in the other direction. and a transmission mechanism disposed in a drive force transmission path from the transmission shaft to the reel, which interrupts the transmission of the driving force when the transmission shaft rotates in the one direction, and prevents the rotation of the transmission shaft from rotating. and a second transmission mechanism that connects the transmission of the driving force when the rotation is in the other direction.

The paper sheet processing device of the present invention includes the above-mentioned paper sheet storage device, an inlet into which the paper sheets are inserted, an outlet through which the paper sheets are discharged, and a paper sheet processing device for transporting the paper sheets from the inlet to the outlet. It has a conveying device that conveys the paper sheets, and an identification device that identifies the type of the paper sheets conveyed by the conveying device, and a plurality of the paper sheet storage devices are arranged along the conveying path of the conveying device. When receiving the paper sheets from the entrance, the transport device transports the paper sheets to a predetermined paper storage device according to the type of the paper sheets identified by the identification device. , when the paper sheets are discharged from the outlet, the paper sheets discharged from the paper sheet storage device are received and conveyed to the outlet.

According to the present invention, the paper sheet storage device disposes at least a part of the motor inside the drum that winds the tape, has a drive shaft protruding from one side of the motor, and from the drive shaft, the drum and reel are connected.

Embodiments of the present invention will be described in detail below with reference to FIGS. 1 to 9. The figures are only shown schematically to provide a thorough understanding of the invention. Therefore, the present invention is not limited to the illustrated example. Further, in each figure, common or similar components are denoted by the same reference numerals, and redundant explanation thereof will be omitted. A bill storage device will be described as an example of a paper sheet storage device. This is a device that uses banknotes as paper sheets and stores and discharges the banknotes. Further, as an example of the paper sheet processing device, a banknote processing device using a banknote storage device will be described.

The structure and operation of the paper sheet storage device will be explained using FIG. 1. FIG. 1 is a diagram illustrating the operation of the paper sheet storage device.

The banknote storage device 1 stores banknotes 2 conveyed from the outside, or discharges banknotes 2 stored inside to the outside. The banknote storage device 1 includes an entrance/exit 16 that communicates between the inside and the outside. The banknotes 2 are stored or ejected through the inlet/outlet 16. The width direction of the banknote 2 is parallel to the entrance/exit 16 . Paper sheets include, for example, valuables such as banknotes, securities, and checks, sheets of paper of a predetermined size, and resin sheets similar to paper.

One end of the first tape 14 is fixed to the first reel 5, and the other end is fixed to the drum 4. One end of the second tape 15 is fixed to the second reel 6, and the other end is fixed to the drum 4.

The movement path of the first tape 14 from the drum 4 to the first reel includes a first guide roller 17, a second guide roller 18, a third guide roller 19, and a third guide roller 17 to move the first tape 14 along a predetermined path. 1 inlet/outlet rollers 22 are arranged, and the first tape 14 is applied to these rollers. The movement path of the second tape 15 from the drum 4 to the second reel includes a fourth guide roller 20, a fifth guide roller 21, and a second entrance/exit roller 23 in order to move the second tape 15 along a predetermined path. A second tape 15 is placed on these rollers.

The first tape 14 is wound on the first reel 5. The second tape 15 is wound on the second reel 6. Further, the first tape 14 and the second tape 15 are overlapped and wound around the drum 4. Banknotes 2 can be sandwiched between the first tape 14 and the second tape 15. The banknote 2 is wound around the drum 4 while being sandwiched between the first tape 14 and the second tape 15. As the first tape 14 and the second tape 15, tapes having approximately the same width as the banknote 2 can be used. It is preferable that the first tape 14 and the second tape 15 have approximately the same width. Further, at least one of the first tape 14 and the second tape 15 may have a width that is approximately the same as the width of the banknote 2. Moreover, when the first tape 14 and the second tape 15 are considered as a pair of tapes, a plurality of tape pairs may be provided in the width direction of the drum 4.

The first entrance/exit roller 22 and the second entrance/exit roller 23 are pressed against each other by an entrance/exit spring 28 . The first tape 14 and the second tape 15 sandwiched between the first entrance/exit roller 22 and the second entrance/exit roller 23 overlap and are wound around the drum 4. When the first tape 14 and the second tape 15 rewound from the drum 4 pass between the first entrance/exit roller 22 and the second entrance/exit roller 23, they are separated. If there is a banknote 2 between the separated first tape 14 and second tape 15, the banknote 2 is separated from the first tape 14 and second tape 15 and is discharged from the inlet/outlet 16.

The first guide roller 17 is movable along the first elongated hole 24. Further, the first guide roller 17 is pulled by the first spring 26 to prevent the first tape 14 from loosening. The fourth guide roller 20 is movable along the second elongated hole 25. Further, the fourth guide roller 20 is pulled by the second spring 27 to prevent the second tape 15 from loosening. The first tape 14 and the second tape 15 are in a stretched state. The first springs 26 are arranged at both ends of the first guide roller 17 and pull both ends of the roller simultaneously. The second springs 27 are similarly arranged at both ends of the fourth guide roller 20.

The transmission shaft 13 drives the drum 4, the first reel 5, and the second reel 6. The transmission shaft 13 and the drum 4 are connected by a first transmission mechanism described later. When the transmission shaft 13 rotates in the first direction (clockwise on the page of FIG. 1), the driving force is transmitted to the drum 4, and the drum 4 rotates in the first direction (clockwise on the page of FIG. 1). Rotate. At this time, the electromagnetic clutch 7 is disconnected, and the driving force is not transmitted to the first reel 5 and the second reel 6. The electromagnetic clutch 7 is a second transmission mechanism that switches whether or not to transmit the driving force of the transmission shaft 13 to the first reel 5 and the second reel 6. Further, the electromagnetic clutch 7 may be replaced with another clutch mechanism as long as the rotation of the first reel 5 and the second reel 6 can be made free by disconnecting and connecting the driving force of the transmission shaft 13.

As the drum 4 rotates, the first tape 14 and the second tape 15 are wound around the drum 4 in an overlapping state. At this time, if the banknote 2 is inserted through the entrance/exit 16, the banknote 2 is sandwiched between the first tape 14 and the second tape 15 and wound around the drum 4. When the first tape 14 is pulled, the first reel 5 rotates, and the first tape 14 is rewound from the first reel 5. Further, as the second tape 15 is pulled, the second reel 6 rotates, and the second tape 15 is rewound from the second reel 6. A brake mechanism is provided on the back side of the third gear 10. A gentle tension can be applied to the first tape 14 and the second tape 15 by the brake mechanism. Moreover, when the drum 4 stops, it is possible to prevent the first reel 5 and the second reel 6 from rotating excessively due to inertial force. The brake mechanism is, for example, a brake that presses a pad against a rotating object using a spring or the like to apply frictional force to resist rotation.

When the transmission shaft 13 rotates in the second direction (counterclockwise on the paper of FIG. 1), no driving force is transmitted to the drum 4, and the electromagnetic clutch 7 is connected. The first transmission mechanism transmits the rotation of the transmission shaft 13 in the first direction to the drum 4, but does not transmit the rotation in the opposite second direction to the drum 4. A one-way clutch, which will be described later, is disposed as a first transmission mechanism in the transmission path of the driving force between the transmission shaft 13 and the drum 4. The rotation of the transmission shaft 13 in the second direction is transmitted to the rotating shaft of the first reel 5 via the first gear 8 , the second gear 9 , the third gear 10 , and the fourth gear 11 . rotates in the direction in which the first tape 14 is wound. Further, the rotation of the transmission shaft 13 in the second direction is transmitted to the rotation shaft of the second reel 6 via the first gear 8, the second gear 9, the third gear 10, and the fifth gear 12, and The reel 6 rotates in the direction in which the second tape 15 is wound. The first reel 5 and the second reel 6 rotate in conjunction with each other, wind the first tape 14 and the second tape 15, respectively, and rewind the first tape 14 and the second tape 15 from the drum 4. Moreover, the first gear 8, the second gear 9, the third gear 10, the fourth gear 11, and the fifth gear 12 can be used as a second conversion mechanism that converts the rotation speed. The first reel 5 and the second reel 6 can be driven by converting the rotation speed of the transmission shaft 13 to a predetermined rotation speed based on the number of teeth of these gear trains.

A first sensor 29 is arranged in a section between the roller pair of the first entrance/exit roller 22 and the second entrance/exit roller 23 and the drum 4 . The first sensor 29 detects the banknote 2 sandwiched between the first tape 14 and the second tape 15. A second sensor 30 is disposed in a section between the second entrance/exit roller 23 and the fifth guide roller 21 . The second sensor 30 detects an end mark on the second tape 15, which will be described later. For example, the first sensor 29 and the second sensor 30 are sensors that include a light emitting section and a light receiving section, and detect light from the light emitting section or reflected light with the light receiving section. Based on changes in the amount of light received, it is possible to detect the presence or absence of banknotes and the presence or absence of changes in the state of the tape.

A light-blocking end mark of 20 cm, for example, is marked in a predetermined length section from one end of the second tape 15. The end mark may be formed by painting the second tape 15 with a color, or by fixing a light blocking sheet with adhesive or the like. Problems will occur if the length of the end mark is too short or too long, so the length of the second tape 15 when wound on the drum 4 is calculated from one turn when the second tape 15 is wound on the second reel. Preferably, the length is between the length of one circumference. End marks of this length can eliminate problems such as manufacturing errors or differences in length when wound.

The end mark is arranged along the edge of the second tape 15 in the detection area of the second sensor 30. When the end mark is detected, winding of the first tape 14 and the second tape 15 is stopped. Preferably, winding of the first tape 14 and the second tape 15 is prohibited when the end mark is detected. It is possible to prevent the first tape 14 and the second tape 15 from being completely rewound from the first reel 5 and the second reel 6. Thereby, the first tape 14 and the second tape 15 can be prevented from coming off the first reel 5 and the second reel 6, and problems such as cutting can also be prevented.

A first elongated hole 24 and a second elongated hole 25 are formed in the frame 3. Further, a first sensor 29 and a second sensor 30 are fixed to the frame 3. The frame 3 also includes a drum 4, a first reel 5, a second reel 6, a first guide roller 17, a second guide roller 18, a third guide roller 19, a fourth guide roller 20, a fifth guide roller 21, and a It supports rollers such as the first entrance/exit roller 22 and the second entrance/exit roller 23.

The frame 3 is equipped with a guide 31, and the inside of the guide 31 is recessed, into which a part of the flange of the drum 4, which will be described later, is rotatably fitted.

FIG. 2 is a diagram illustrating the internal configuration of the paper sheet storage device.

A back cover 38 is arranged on the outside of the frame 3, and the back cover 38 covers the bearings and the like so that they are not exposed. The entrance/exit spring 28 is also provided between the frame 3 and the back cover 38, and biases the roller. Further, each roller is vertically supported by the frame 3.

Here, the general structure of the electromagnetic clutch 7 will be explained using FIG. 9. FIG. 9 is a schematic diagram illustrating the operation of the clutch. The first rotor 77 and the second rotor 78 are moved toward and away from each other by the magnetic drive section 76 . The transmission shaft 13 is fixed to the first rotor 77 by a clutch fixing part 59. A first gear is fixed to the second rotor 78. A first rotor 77 is rotatably disposed on the clutch frame 75. The magnetic drive unit 76 is fixed to the first rotor 77 . The second rotor 78 is rotatable and disposed on the clutch frame 75 so as to be able to move toward and away from the first rotor 77 . When a current is applied to the magnetic drive section 76, a magnetomotive force is generated in the magnetic drive section 76, and the second rotor 78 is attracted to the first rotor 77. The drawn second rotor 78 is fixed to and interlocks with the first rotor 77. At this time, when the transmission shaft 13 is rotated, the second rotor 78 rotates together with the first rotor 77. When the current flowing through the magnetic drive section 76 is cut off, the magnetomotive force of the magnetic drive section 76 disappears, and the second rotor 78 separates from the first rotor 77. The second rotor 78 is rotatable independently of the first rotor 77. A knob 53 is fixed to the transmission shaft 13 in order to manually rotate the transmission shaft 13. The connecting portion 79 connects and disconnects the knob 53 and the first gear 8 by manual operation. The knob 53 can rotate the first gear 8 via the connecting portion 79 . The drum 4 (see FIG. 2), the first reel 5 (see FIG. 2), and the second reel (see FIG. 2) can be rotated by the knob 53. Since the knob 53 is used when manually inserting and removing banknotes, it is not necessarily necessary if manual operation is not required.

Now, returning to FIG. 2, the drum 4, first reel 5, and second reel 6 will be explained.

The first reel 5 has a cylindrical shape and is provided with first reel flanges 34 at both ends. One end of the first tape 14 (see FIG. 1) is fixed to the surface of the first reel 5 by being sandwiched between first reel mounting plates 35 arranged along the width direction of the first tape 14. The first tape 14 (see FIG. 1) is wound around the first reel 5 and stored between first reel flanges 34 arranged at both ends of the first reel 5.

The second reel 6 has a cylindrical shape and is provided with second reel flanges 36 at both ends. One end of the second tape 15 (see FIG. 1) is fixed to the surface of the second reel 6 by being sandwiched between second reel mounting plates 37 arranged along the width direction of the second tape 15. The second tape 15 (see FIG. 1) is wound around the second reel 6 and stored between second reel flanges 36 arranged at both ends of the second reel 6.

The drum 4 has a cylindrical shape and is provided with drum flanges 32 at both ends. The other end of the first tape 14 (see FIG. 1) and the other end of the second tape 15 (see FIG. 1) are attached to the surface of the drum 4 in the width direction of the first tape 14 and the second tape 15. It is sandwiched and fixed between drum mounting plates 33 arranged along the drum. The first tape 14 (see FIG. 1) and the second tape 15 (see FIG. 1) are overlapped, wound around the drum 4, and housed between drum flanges 32 disposed at both ends of the drum 4.

The drum and reel are provided with flanges. The flange straightens the tape so that it does not extend beyond the end of the drum or reel. Moreover, the shaft of the fourth guide roller 20 is movable along the second elongated hole 25, and is biased by a spring. If the tape is bent, the fourth guide roller 20 can correct the bend. The first guide roller 17 (see FIG. 1) also has the same function as the fourth guide roller 20. The width of the area where the tape is wound between the drum flanges 32 is made slightly wider than the width of the tape wound around the drum 4 and the banknote. Preferably, the width of the tape wrapping area between the drum flanges 32 is 1 to 10 mm wider than the width of the tape or banknote. Even if bending and the like are taken into consideration, the drum can suitably wind the tape. The widths of the first reel 5 and the second reel 6 are also the same as the width of the drum 4.

Next, the internal structure of the banknote storage device 1 will be explained using FIG. 3. FIG. 3 is a diagram illustrating the inside of the drum of the paper sheet storage device. 3 is a perspective view of the banknote storage device 1 shown in FIG. 2 with the drum, reel, roller, and gear removed, although the perspective direction is different from that of FIG. 2.

The inner side of the guide 31 of the frame 3 is depressed to form a recess 41. A cylindrical base 40 is fixed to the recess 41 with base mounting screws 44 . A motor and a speed reduction mechanism, which will be described later, are housed inside the base 40. A screw hole 43 is provided at one end of the base 40 . The screw hole 43 is a hole through which a screw for fixing a motor and a transmission mechanism, which will be described later, are placed inside the base 40. A through hole (not shown) for passing the transmission shaft 13 therethrough is provided at the center of one end of the base 40 . A bearing, which will be described later, is fixed in the through hole, and the bearing rotatably supports the transmission shaft 13. A one-way clutch 42 is fixed to the transmission shaft 13, and a drum 4 (see FIG. 2) is fixed to the one-way clutch 42. The base 40 supports the transmission shaft 13, a built-in motor (not shown), and a speed reduction mechanism, and is fixed to the frame 3.

The frame 3 is provided with reel attachment holes 46 for supporting the first reel 5 (see FIG. 2) and the second reel 6 (see FIG. 2).

A connector 45 protrudes outward from the end of the back cover 38. A control circuit (not shown) is provided inside the back cover 38 and controls the banknote storage device 1. A control circuit (not shown) is connected to the connector 45. The external control device connects power and signal lines to the control circuit via the connector 45 and performs control.

FIG. 4 is a diagram illustrating a drum drive mechanism of the paper sheet storage device. FIG. 3 is a cross-sectional view for explaining a drive mechanism of the banknote storage device 1. FIG.

In the banknote storage device 1, a drive mechanism and the like are covered by a frame 3, a back cover 38, a case side part 50, and a cover 51. A knob 53 protrudes from the cover 51, and the transmission shaft 13 and first gear 8 can be rotated manually.

A motor 54 and a speed reduction mechanism 56 are fixed inside a base 40 fixed to the frame 3. Motor 54 rotates in a first direction and an opposite second direction. A rotating shaft 55 protrudes from one end of the motor 54. The rotating shaft 55 is fixed to the first sun gear 62 . The speed reduction mechanism 56 has a speed reduction ratio determined based on the gears that constitute the speed reduction mechanism 56, and converts the input rotation speed into a predetermined speed. The speed reduction mechanism 56 can also be said to be a first conversion mechanism that converts the rotation speed.

The output of the speed reduction mechanism 56 is the rotation of the third sun gear 70 , and the transmission shaft 13 is fixed to the transmission shaft fixing portion 74 of the third sun gear 70 .

The transmission shaft 13 is rotatably supported by a bearing 57 located at the center of one end of the base 40 . The bearing 57 is fixed to a through hole located at the center of one end of the base 40.

The transmission shaft 13 protrudes from the base 40, and a one-way clutch 42 is fixed near the bearing 57. The drum 4 is fixed to the one-way clutch 42. By arranging the one-way clutch 42 near the bearing 57, the vibration of the shaft can be reduced. Further, a tape is wound in the space between the drum flanges 32 of the drum 4.

A partition plate 52 is provided at one end of the case side portion 50 . The partition plate 52 separates the drum 4 drive mechanism from the reel drive mechanism. The partition plate 52 is provided with a through hole through which the transmission shaft 13 passes. The pin 60 is a connection means for connecting the knob 53 to the transmission shaft 13, and can also be connected to the first gear 8 by manual operation.

A clutch frame 75 (see FIG. 9) of the electromagnetic clutch 7 is fixed to the partition plate 52. The electromagnetic clutch 7 switches whether or not to transmit the rotation of the transmission shaft 13 to the first gear 8 according to ON/OFF of the input current.

The speed reduction mechanism 56 can also be said to be a conversion mechanism that rotates the rotation shaft 55 of the motor 54 at a predetermined number of rotations and rotates the transmission shaft 13 at a predetermined number of rotations. The speed reduction mechanism 56 inputs the rotation of the rotary shaft 55 and outputs it to the transmission shaft 13 at a predetermined rotation speed. The deceleration mechanism 56 is configured by connecting three planetary gear mechanisms, and decelerates the rotation speed at a predetermined ratio.

The motor 54 is fixed to the speed reduction mechanism base 61 by a motor fixing screw 58. The connecting portion 73 fixes the three-stage planetary gear mechanism, the reduction mechanism base 61, and the motor 54, and is further fixed to the base 40. For example, each planetary gear mechanism, the reduction mechanism base 61, and the base 40 are connected and fixed with screws.

A first sun gear 62 fixed to the rotating shaft 55 meshes with a first planetary gear 63. Three first planet gears 63 are arranged around the first sun gear 62. The first planetary gear 63 meshes with the first internal gear 64. The first internal gear 64 is fixed to the connecting portion 73. The rotation shaft of each first planetary gear 63 is a first planetary carrier 65 that slides on the reduction mechanism base 61. Since the first internal gear 64 is fixed, the first planetary carrier 65 rotates. The tip of the first planet carrier 65 meshes with the base portion of the second sun gear 66. When the first planet carrier 65 rotates, the second sun gear 66 rotates.

The second planetary gear 67 meshes with the second sun gear 66 . Three second planet gears 67 are arranged around the second sun gear 66. The second internal gear 68 is fixed to the connecting portion 73. The rotation axis of the second planet gear 67 is a second planet carrier 69 that slides on the base portion of the second sun gear 66 . Since the second internal gear 68 is fixed, the second planetary carrier 69 rotates. The tip of the second planetary carrier 69 meshes with the base portion of the third sun gear 70 . When the second planet carrier 69 rotates, the third sun gear 70 rotates.

The third planetary gear 71 meshes with the third sun gear 70. Three third planetary gears 71 are arranged around the third sun gear 70. The third internal gear 72 is fixed to the connecting portion 73. The transmission shaft 13 is fixed to the third sun gear 70 by a transmission shaft fixing portion 74 . The third sun gear 70 rotates in conjunction with the transmission shaft 13. That is, the transmission shaft 13 is connected to the final stage of the speed reduction mechanism 56.

A part of the motor 54, a speed reduction mechanism 56, and a one-way clutch 42 are arranged inside the drum 4. The motor 54 can also be entirely housed inside the drum 4. Although a part of the speed reduction mechanism 56 can be placed between the drum 4 and the partition plate 52, the mechanism becomes complicated. A transmission shaft 13 passing through the drum 4 is connected to the electromagnetic clutch 7 with a partition plate 52 in between. The motor 54 and the speed reduction mechanism 56 are housed inside the base 40 and separated from the drum 4. By separating the portion of the drum 4 that stores the tape from the transmission mechanism portions such as the motor 54 and the speed reduction mechanism 56, it is possible to block dust generated in each area. It is also possible to arrange the electromagnetic clutch 7 inside the drum 4. In that case, it is necessary to provide a transmission mechanism that transmits the rotation of the first gear 8 or the output of the electromagnetic clutch 7 to the first reel 5 (see FIG. 1) and the second reel 6 (see FIG. 1).

The banknote storage device 1 includes a rotating shaft 55, a deceleration mechanism 56, a one-way clutch 42, an electromagnetic clutch 7, and a drive force from the electromagnetic clutch 7 to the first reel 5 (see FIG. 1) and the second reel 6 (see FIG. 1). A transmission mechanism is located on one side of the motor 54. Furthermore, some of these are arranged inside the drum 4. Since the mechanical parts are concentrated on one side of the banknote storage device 1, the width of the banknote storage device 1 can be made narrower. This made it possible to downsize the banknote storage device 1.

The third sorting section 96 guides the third denomination to the banknote storage device 1 and allows other denominations to pass through. The first denomination, the second denomination, and the third denomination are the denominations of the banknote determined by the first functional unit 92.

Three banknote storage devices 1 are attached to the lower unit 87. The lower unit 87 is provided with a guide rail 97 that guides the bill storage device 1 in order to mount the bill storage device 1 in a predetermined position. The banknote processing device 85 can feed out banknotes from the banknote storage device 1 and convey them to the withdrawal port 91.

The first functional unit 92 and the second functional unit 93 may be units having other functions such as a functional unit for smoothing wrinkles in banknotes, but at least one is provided with an identification unit that identifies the denomination of the banknote. Moreover, it is possible to identify the type of paper sheets other than banknotes, and the first functional unit 92 can be used as an identification unit that identifies the type of paper sheets.

The banknotes inserted into the deposit slot 89 are transported by a transport section 90 including a transport device. The denomination of the banknote is identified by the first functional unit 92 . The banknotes are then sterilized by the second functional unit 93. Next, the banknotes are guided and stored in banknote storage devices 1 arranged for each denomination. Further, the banknotes stored in the banknote storage device 1 are transferred from the banknote storage device 1 to the conveyance section 90 and conveyed to the withdrawal port 91.

For example, the banknote processing device 85 may be a currency exchange machine that identifies the denomination of a deposited banknote, changes it to a banknote of another denomination, and withdraws the money, or an automatic payment machine that accepts the price of a product and withdraws change.
