  For example, a stage 32 that is movable in a vertical direction perpendicular to the floor surface is incorporated in the storage box 31. Bills 41 are stacked on the stage 32. The bills are stacked on the stage 32 by the action of a pair of rollers including the transport rollers 33-1 and 33-2.

Similarly, banknotes stacked on the stage 32 are fed out of the storage box 31 by the action of a pair of rollers including transport rollers 33-1 and 33-2.
The configurations of the first stacker 25 and the second stacker 26 will be described later.

FIG. 3 is a configuration diagram of the stacker according to the first embodiment.
Here, the first stacker 25 will be described.
The first stacker 25 includes a storage box 31, transport rollers 33-1, 33-2, 33-3, a deposit removal roller 34, an ultraviolet irradiation device 35, and a bill detection sensor 36.

For example, a stage 32 that is movable in a vertical direction perpendicular to the floor surface is incorporated in the storage box 31. Bills 41 are stacked on the stage 32.
The conveyance rollers 33-1, 33-2, 33-3 and the deposit removal roller 34 are provided at the entrance / exit of the storage box 31.

A conveyance path 37 through which the bills 41 are conveyed passes through the gap between the deposit removal roller 34 and the conveyance roller 33-3.
The banknote 41 being conveyed by the conveyance path 37 passes through the gap between the deposit removing roller 34 and the conveyance roller 33-3 and the gap between the conveyance roller 33-1 and the conveyance roller 33-2 and is accommodated in the accommodation box 31. Is done.

  Further, when the banknote 41 is fed out from the storage box 31, it passes through the gap between the conveyance roller 33-1 and the conveyance roller 33-2 and the gap between the deposit removing roller 34 and the conveyance roller 33-3.

When the banknote 41 is stored or delivered, the banknote 41 passes through the gap between the deposit removal roller 34 and the transport roller 33-3.
That is, since the bill 41 comes into contact with the deposit removal roller 34, the deposit 41 is adsorbed by the deposit removal roller 34.

  In addition, when the banknote 41 is adsorbed to the deposit removing roller 34, it is detected by the banknote detection sensor 36, the banknote 41 is peeled from the deposit removing roller 34, and is returned to the genuine note collection chamber 24 through the collection path 38. Transport.

Here, details of the deposit removal roller 34 will be described.
The deposit removing roller 34 is covered with a polymer material such as resin, rubber, or thermoplastic elastomer.

The polymer material includes a photocatalytic material having adsorptivity and decomposability.
The photocatalytic material is preferably photocatalytic apatite.
In the embodiment, metal-modified apatite is used as the photocatalytic apatite.

The metal-modified apatite has a chemical structure in which a part of Ca of calcium hydroxyapatite is substituted with a photocatalytic metal such as Ti. The apatite constituting the main skeleton of the metal-modified apatite can be expressed by the following formula.
Ax （BOy) zXs ・ ・ ・ （1）

  A in Formula (1) is calcium (Ca), cobalt (Co), nickel (Ni), copper (Cu), aluminum (Al), lanthanum (La), chromium (Cr), iron (Fe), magnesium ( Represents a metal atom such as Mg). B represents an atom such as phosphorus (P) or sulfur (S). X is a hydroxyl group (—OH) or a halogen atom (eg, F, Cl). More specifically, examples of the apatite include hydroxyapatite, fluoroapatite, chloroapatite, tricalcium phosphate, and calcium hydrogen phosphate.

The apatite that can be suitably used in the embodiment is a calcium hydroxide in which A in the above formula (1) is calcium (Ca), B is phosphorus (P), and X is a hydroxyl group (—OH). It is apatite (hereinafter sometimes referred to as “CaHAP”), that is, Ca ₁₀ (PO ₄ ) ₆ (OH) ₂ .

  The photocatalytic metal in the embodiment refers to a metal atom that can function as a photocatalytic center in an oxide state, such as Ti (titanium), zirconium (Zr), iron (Fe), tungsten (W), and the like. .

  When such a photocatalytic metal is incorporated into the apatite crystal structure as a part of the metal atom constituting the crystal structure of the apatite represented by the above formula (1), the catalyst is used as a physical property of the entire crystal in the apatite crystal structure. It is considered that a catalytic partial structure capable of exhibiting a function is formed.

  More specifically, the catalytic partial structure here is composed of a photocatalytic metal incorporated in place of a part of A in the above formula (1) and an oxygen atom in the above formula (1), and is apatite. It is a metal oxide structure necessary to develop a photocatalytic function as a physical property of crystals.

  In the embodiment, titanium apatite in which a part of Ca of calcium hydroxyapatite is substituted with Ti is used as the metal-modified apatite. The metal-modified apatite has adsorptivity, and by using it for the deposit removal roller 34, the deposit removal roller 34 can adsorb the deposit adhering to the banknote.

A method of manufacturing the deposit removing roller 34 that is coated with a polymer material such as resin, rubber, or thermoplastic elastomer will be described.
Since the metal-modified apatite is a powder, it is dispersed in the polymer material and applied to the deposit removing roller 34. Alternatively, the metal-modified apatite is dispersed in a sheet made of a polymer material and wound around a roller. By using the sheet, it is possible to attach and detach the roller.

  Examples of the resin used for the deposit removing roller 34 include silicon-containing weight bodies, fluorine-containing weight bodies, epoxy resins, urethane resins, saturated polyester resins, unsaturated polyester resins, melamine resins, phenol resins, amide resins, and ketone resins. , Acrylic resin, vinyl resin, hydrocarbon resin and the like.

  Examples of the rubber used for the deposit removing roller 34 include acrylic rubber, nitrile rubber, isoprene rubber, urethane rubber, ethylene propylene rubber, epichlorohydridone rubber, polysulfide rubber, chlorosulfonated polyethylene, chloroprene rubber, silicone rubber, and styrene. -There are butadiene rubber, butadiene rubber, butadiene-methacrylate rubber, fluorine rubber, polyisobutylene, etc.

  Examples of the thermoplastic elastomer used for the deposit removing roller 34 include styrene, olefin, polyvinyl chloride (PVC), urethane, ester, and amide.

  According to the inventor's experimental results, the metal-modified apatite is preferably in the range of 3 to 11 mol% from the viewpoint of effectively improving both the adsorptivity and the decomposability of the metal-modified apatite.

The ultraviolet irradiation device 35 is installed in the vicinity of the deposit removal roller 34.
The ultraviolet irradiation device 35 irradiates the deposit removing roller 34 with ultraviolet rays (having a wavelength of less than 400 nm, for example, 340 to 380 nm). Then, the substance adhering to the adhering matter removing roller 34 is decomposed and removed into water and carbon dioxide.

  In order to reduce the influence on the living body, it is desirable to use near ultraviolet rays (wavelength is 380 to 200 nm), and it is further desirable to use UV-A (wavelength is 315 to 380 nm). According to the inventor's experimental results, according to the inventor's experimental results, the deposits can be decomposed by low energy ultraviolet rays such as UV-A.

Since the second stacker 26 has the same configuration, the description thereof is omitted.
FIG. 4 is a configuration diagram of the deposit removal mechanism provided in the transport path.
FIG. 4 corresponds to, for example, the deposit removal mechanism provided on the transport path 37 before the entrance / exit of the genuine note temporary storage chamber 23.

The deposit removal mechanism includes a transport roller 33-3, a deposit removal roller 34, an ultraviolet irradiation device 35, and a bill detection sensor 36.
The configurations of the deposit removal roller 34, the ultraviolet irradiation device 35, and the banknote detection sensor 36 are the same as those described above, and a detailed description thereof will be omitted.

The conveyance roller 33-3 and the deposit removal roller 34 constitute a pair of rollers.
A conveyance path 37 through which the bills 41 are conveyed passes through the gap between the deposit removal roller 34 and the conveyance roller 33-3.

  For example, when a bill is stored in the genuine note temporary storage chamber 23, the bill 41 passes through the gap between the deposit removal roller 34 and the transport roller 33-3. That is, the banknote 41 comes into contact with the deposit removal roller 34. As described above, the deposit removing roller 34 has adsorbability, so that deposits on the banknote 41 are attracted to the deposit removing roller 34.

  In the first embodiment, the deposit removing mechanism is installed in the transport path 37 in front of the entrance / exit of the genuine note temporary storage chamber 23 or the transport path 37 in front of the entrance / exit of the feeding unit 21. It is not limited, and it can be installed at any place on the conveyance path 37.

FIG. 5 is a diagram showing adsorption, decomposition, and removal of deposits.
FIG. 5 shows adsorption, decomposition, and removal of deposits in order from the left side.
When the banknote 41 sent by the transport path 37 comes into contact with the deposit removal roller 34, the deposit 42 attached to the bill 41 is adsorbed by the deposit removal roller 34.

Then, the deposit removing roller 34 is irradiated with ultraviolet rays from the ultraviolet irradiation device 35, and when the ultraviolet rays are irradiated, the deposit 42 on the deposit removing roller 34 is decomposed.
The decomposed substance is discharged out of the ATM 11 by the ATM 11 exhaust mechanism.

Thus, since the deposit | attachment 42 is removed from the banknote 41, the banknote 41 becomes static-removed or becomes difficult to be charged.
Further, since the deposit 42 on the deposit removing roller 34 is decomposed and removed by the ultraviolet rays, the deposit removing roller 34 becomes maintenance-free.

FIG. 6 is a diagram illustrating a state in which bills are adsorbed to the deposit removal roller.
As shown in FIG. 6, the deposit removing roller 34 not only adsorbs only the deposit 42 attached to the bill 41, but also may attract the bill 41.

In ATM11 of embodiment, the presence or absence of the banknote 41 adsorb | sucked to the deposit | attachment removal roller 34 is detected by the banknote detection sensor 36. FIG.
Ultraviolet light-emitting ink is used for the seal on the surface of the banknote 41 and the background pattern on the front and back surfaces. Therefore, the presence or absence of the banknote 41 adsorbed on the deposit removing roller 34 can be detected by using, for example, a sensor having a function of detecting ultraviolet light emission as the banknote detection sensor 36.

  In ATM11 of embodiment, when the banknote 41 is detected by the banknote detection sensor 36, the banknote 41 adsorb | sucked to the deposit | attachment removal roller 34 will peel from the deposit | attachment removal roller 34, and the deposit | attachment removal roller 34 is pinched | interposed. It is sent to a collection path 38 provided on the opposite side of the conveyance path 37, and is sent to the genuine note collection chamber 24 or the feeding unit 21 by the collection path 38.

FIG. 7 is a flowchart showing the deposit removal process of the embodiment.
The ATM 11 detects whether or not the door 39 of the ATM 11 is closed by a door sensor (not shown) (S51). When the door 39 is closed (S51, YES), the ultraviolet irradiation device 35 is activated (S51). S52) If the door 39 is not closed (S51, NO), the process is terminated. Thus, for the safety of the human body, when the ATM door 39 is open, ultraviolet rays are not irradiated.

When processing such as depositing is performed at the ATM 11, a bill 41 with an adhering substance appears on the transport path 37, and the bill is transported (S53).
The banknote contacts the deposit removal roller 34 provided in the middle of the conveyance path 37 or in the stacker, and the deposit removal roller 34 adsorbs the deposit 42 of the bill 41 (S54).

  The banknote detection sensor 36 detects whether or not there is a banknote 41 on the deposit removal roller 34. (S55). When the banknote detection sensor 36 detects the banknote 41 on the deposit removal roller 34 (S55, YES), the unpurified banknote 41 is peeled from the deposit removal roller 34 and sent to the collection path 38.

When the banknote detection sensor 36 does not detect the banknote 41 on the deposit removal roller 34 (S55, NO), the banknote 41 (purified banknote) from which the deposit 42 has been removed is conveyed to the stackers 25 and 26, and the stacker 25 , 26 (S57).
The deposit removing roller 34 is irradiated with ultraviolet rays from the ultraviolet irradiation device 35, and the deposit 42 on the deposit removing roller 34 is decomposed and removed (S58).

FIG. 8 is a cross-sectional view of an ATM according to the second embodiment.
In addition, in the following description, since what attached | subjected the same code | symbol in drawing | drawing shows the same thing and the same effect, description may be abbreviate | omitted.

  Compared with the ATM 11 according to the first embodiment, the ATM 45 according to the second embodiment is provided at the entrance / exit of the storage box 31 of the stackers 25 and 26 in the ATM 11 according to the first embodiment. The adhering matter removing roller 34, the transport roller 33-3, the ultraviolet irradiation device 35, and the banknote detection sensor 36 are provided not on the entrance / exit of the storage box 31 but on the transport path 37 in front of the safe 20.

  The banknote 41 is conveyed by the conveyance path 37 when accommodated in the stackers 25 and 26, and a gap between a pair of rollers including a deposit removing roller 34 and a conveyance roller 33-3 provided on the conveyance path 37 in front of the safe 20 is stored. Pass through. Thereby, the adhering matter adhering to the banknote 41 is adsorbed by the adhering matter removing roller 34.

  Like the ATM 45 according to the second embodiment, the stacker in the safe 20 having a limited place does not have a deposit removing mechanism including the deposit removing roller 34, the ultraviolet irradiation device 35, etc. By providing on the transport path 37 on the near side, an effect equivalent to that of the first embodiment can be obtained.

FIG. 9 is a cross-sectional view of an ATM according to the third embodiment.
Compared with the ATM 11 according to the first embodiment, the ATM 46 according to the third embodiment has a deposit removing roller 34 and a conveying roller 33-3 in addition to the configuration of the ATM 11 according to the first embodiment. Further, an ultraviolet irradiation device 35 and a banknote detection sensor 36 are further provided on a transport path 37 in front of the safe 20.

  Like the ATM 43 according to the third embodiment, the attachment of the banknote 41 is provided by providing more deposit removing rollers 34 than the ATM 11 according to the first embodiment and the ATM 45 according to the second embodiment. The kimono can be removed more. Thereby, the antistatic effect is further improved.

FIG. 10 is a cross-sectional view of an ATM according to the fourth embodiment.
In the ATM 47 according to the fourth embodiment, the deposit removing roller 34 has adsorbability and decomposability in the ATM 11 according to the first embodiment as compared with the ATM 11 according to the first embodiment. Although it was coated with a polymer material including a photocatalytic material, in the fourth embodiment, at least a part of the contact surface with the banknote 41 of the deposit removing belt 48 arranged instead of the conveyance path 37 is the same. It is covered with a polymer material. Therefore, the deposit removing belt 48 can maintain elasticity. The description of the polymer material and the like coated on the deposit removing belt 48 has been described above, and will be omitted.

  Further, in the fourth embodiment, a conveyance roller 49 that is not covered with the above-described polymer material is disposed instead of the deposit removal roller 34. However, the deposit removing roller 34 may be disposed, and both the deposit removing roller 34 and the deposit removing belt 48 may be irradiated with ultraviolet rays by the ultraviolet irradiation device 35, respectively.

  The deposit removing belt 48 may not be covered as described above over the entire conveyance path, and only a part of the belt in the conveyance path may be covered. In that case, the deposit removing belt 48 is preferably covered with a portion that comes into contact with the banknote 41 immediately after being inserted into the ATM 11, such as a conveyance path between the feeding unit 21 and the discrimination unit 22.

  Moreover, in 4th Embodiment, the ultraviolet irradiation device 35 and the banknote detection sensor 36 which were provided in the entrance / exit of the storage box 31 of the stackers 25 and 26 are the deposit | attachment in front of the safe 20 instead of the entrance / exit of the storage box 31. It is provided on the removal belt 48. It is desirable that the ultraviolet irradiation device 35 and the banknote detection sensor 36 be installed at a position where the deposit removing belt 48 can be irradiated with ultraviolet rays efficiently without interfering with other devices such as existing sensors.

FIG. 11 is a configuration diagram of the deposit removal mechanism provided in the transport path according to the fourth embodiment.
The deposit removing mechanism shown in FIG. 11 corresponds to the deposit removing mechanism provided on the deposit removing belt 48 in front of the entrance / exit of the genuine note temporary storage chamber 23, for example.

The deposit removal mechanism includes a deposit removal belt 48, an ultraviolet irradiation device 35, and a banknote detection sensor 36.
The deposit removal belt 48 passes through the gap between the transport roller 49 and the transport roller 33-3 so that the banknote 41 is transported.

  For example, when a bill is stored in the genuine note temporary storage chamber 23, the bill 41 passes through the gap between the transport roller 49 and the transport roller 33-3. In particular, at this time, the deposit on the bill 41 is adsorbed by the deposit transport belt 48.

  For example, the ultraviolet irradiation device 35 irradiates the ultraviolet light L to a position where the banknote detection sensor 36 detects that there is no banknote 41 (for example, detection by the ultraviolet light L as described above). In addition, the ultraviolet irradiation device 35 may detect the location where the banknote 41 was present by the banknote detection sensor 36 and irradiate the location with the ultraviolet light L after the banknote 41 is conveyed.

  The deposit removing belt 48 may attract not only the deposit 42 but also the bill 41, but the bill detection sensor 36 can also detect the suction of the bill 41. The bill 41 adsorbed by the deposit removing belt 48 may be sent from the collection path 38 or the like to the genuine note collection chamber 24 or the feeding unit 21 as in the above-described embodiment.

  Also in the fourth embodiment, the deposit removing mechanism is provided on the transport path 37 before the entrance / exit of the genuine note temporary storage chamber 23 or the transport path (attachment transport belt 48) before the entrance / exit of the feeding unit 21. Although it installed, it is not restricted to the said location, It is possible to install in arbitrary places on a conveyance path | route (attached material conveyance belt 48).

12 and 13 are a plan view and a cross-sectional view showing adsorption, decomposition, and removal of deposits.
12 and 13 show the adsorption, decomposition, and removal of deposits in order from the left side.

As shown in FIG. 12, the deposit removing belt 48 is composed of, for example, a pair of rubber belts.
In particular, when the bill 41 sent by the deposit removing belt 48 comes into contact with rollers such as the transport rollers 49 and 33-3, the deposit 42 adhering to the bill 41 is adhered to the deposit removing belt 48 (see FIG. 13 is adsorbed on the covering portion 48a). Therefore, as shown in the center of FIG. 12, after the bill 41 is conveyed, the deposit 42 is adsorbed to the deposit removing belt 48 at a portion where the bill 41 exists (shown by a two-dot chain line).

For example, the deposit removing belt 48 is irradiated with the ultraviolet rays L from the ultraviolet irradiation device 35 at a specific cycle in a place where the banknote 41 does not exist or at a specific timing in a place where the banknote 41 exists. When the ultraviolet ray L is irradiated, the deposit 42 on the deposit removing roller 48 is decomposed into water (H ₂ O) and carbon dioxide (CO ₂ ).

The decomposed substance is discharged out of the ATM 11 by the ATM 11 exhaust mechanism.
Thus, since the deposit | attachment 42 is removed from the banknote 41, the banknote 41 becomes static-removed or becomes difficult to be charged.

  Further, since the deposit 42 on the deposit removing belt 48 is decomposed and removed by the ultraviolet rays L, the deposit removing belt 48 becomes maintenance-free. By the way, dirt easily adheres to the transport path, and maintenance of the transport path is more burdensome than the above-described roller. In that respect, in the fourth embodiment, the deposit 42 of the deposit removing belt 48 is decomposed and removed, so that the maintenance-free effect in the fourth embodiment is extremely large.

  Furthermore, alcohol for maintenance of the conveyance path (belt) is sold, but in the fourth embodiment, deterioration of materials such as rubber is suppressed as compared with the deposit removing agent such as alcohol. This also contributes to maintenance-free.

FIG. 14 is a flowchart illustrating the deposit removal process according to the fourth embodiment.
The process of FIG. 14 is mainly different from the process of FIG. 7 in that the deposit removing belt 48 is irradiated with ultraviolet rays instead of the deposit removing roller 34.

  The ATM 47 detects whether or not the door 39 of the ATM 47 is closed by a door sensor (not shown) (S61). When the door 39 is closed (S61, YES), the ultraviolet irradiation device 35 is activated (S61). S62) If the door 39 is not closed (S61, NO), the process is terminated. Thus, for the safety of the human body, when the ATM door 39 is open, ultraviolet rays are not irradiated.

When processing such as depositing is performed at the ATM 47, the bill 41 with the deposit 42 appears on the deposit removing belt 48, and the bill 41 is conveyed (S63).
For example, when the bill 41 comes into contact with the roller, the deposit removal belt 48 sucks the deposit 42 of the bill 41 (S64).

  The banknote detection sensor 36 detects whether or not there is an unintended banknote 41 on the deposit removal belt 48. (S65). When the banknote detection sensor 36 detects the banknote 41 on the deposit removal belt 48 (S65, YES), the unpurified banknote 41 is peeled from the deposit removal belt 48 and sent to the collection path.

When the banknote detection sensor 36 does not detect the banknote 41 on the deposit removal belt 48 (S65, NO), the banknote 41 (purified banknote) from which the deposit 42 has been removed is conveyed to the stackers 25 and 26, and the stacker 25 , 26 (S67).
The deposit removing belt 48 is irradiated with ultraviolet rays from the ultraviolet irradiation device 35, and the deposit 42 on the deposit removing belt 48 is decomposed and removed (S68).

Next, a hardware configuration example of a control unit that performs a control process (the flowcharts of FIGS. 7 and 14) that causes the ATM 11 to remove deposits will be described with reference to FIG.
In the configuration example of FIG. 15, the computer 70 includes an MPU 71, ROM 72, RAM 73, hard disk device 74, input device 75, output device 76, interface device 77, and recording medium drive device 78. These components are connected via a bus line 79, and various data can be exchanged under the management of the MPU 71.

An MPU (Micro Processing Unit) 71 is an arithmetic processing unit that controls the operation of the entire computer 70.
A ROM (Read Only Memory) 72 is a read-only semiconductor memory in which a predetermined basic control program is recorded in advance. The MPU 71 reads out and executes this basic control program when the computer 70 is activated, thereby enabling operation control of each component of the computer 70.

  A RAM (Random Access Memory) 73 is a semiconductor memory that can be written and read at any time and used as a working storage area as necessary when the MPU 71 executes various control programs.

  The hard disk device 74 is a storage device that stores various control programs executed by the MPU 71 and various data. The MPU 71 can perform various control processes by reading and executing a predetermined control program stored in the hard disk device 74.

  The input device 75 is, for example, a touch panel switch or a keyboard device. The input device 75 acquires various information input from the user associated with the operation content, and sends the acquired input information to the MPU 71.

The output device 76 is, for example, a liquid crystal display or a speaker, and displays various texts and images according to display data sent from the MPU 71.
The interface device 77 is connected to a drive unit for the conveyance path 37 (adherent removal belt 48), an ultraviolet irradiation device 35, and the like. The interface device 77 manages transmission / reception of various kinds of information between the driving device of the conveyance path 37 or the ultraviolet irradiation device 35, or various units such as various sensors 28, 29, 36 not shown in FIG. Do.

  The recording medium driving device 78 is a device that reads various control programs and data recorded on the portable recording medium 80. The MPU 71 can perform various control processes by reading and executing a predetermined control program recorded on the portable recording medium 80 via the recording medium driving device 78. As the portable recording medium 80, for example, a flash memory equipped with a CD-ROM (Compact Disc Read Only Memory), a DVD-ROM (Digital Versatile Disc Read Only Memory), or a USB (Universal Serial Bus) standard connector. and so on.

  In order to cause the ATM 11 to perform the deposit removal process using such a computer 70, for example, a control program for causing the MPU 71 to perform the deposit removal process described above is created. The created control program is stored in advance in the hard disk device 74 or the portable recording medium 80. Then, a predetermined instruction is given to the MPU 71 to read and execute this control program. By doing so, the configuration of FIG. 15 makes it possible to provide the functions that each part of the ATM 11 has.

As another embodiment, a visible light irradiation device that irradiates visible light (wavelength: 380 nm to 750 nm) can be used instead of the ultraviolet irradiation device 35.
By adding a sensitizer (also referred to as a sensitizing dye) for causing the photocatalyst material used for the deposit removing roller 34 to react with visible light, the deposit can be decomposed with visible light.

For example, titanium apatite itself can use only ultraviolet rays, but visible light can be used by adsorbing a sensitizer that absorbs visible light to titanium apatite.
As the sensitizer, inorganic dyes (for example, Ru dyes) or organic dyes (for example, coumarin derivatives, mercurochrome dyes, cyanine dyes, methocyanine dyes, xanthene dyes) can be used. These sensitizers are used alone or in combination.

The sensitizer is preferably 0.00005 to 10% by weight, more preferably 0.0005 to 5% by weight of titanium apatite.
In the first to third embodiments described above, only one roller sandwiching the conveyance path 37 is used as the deposit removal roller 34. However, both rollers sandwiching the conveyance path 37 may be used as the deposit removal roller 34. good.

  In the first to third embodiments, when a plurality of deposit removing rollers 34 are provided, it is desirable that the deposit removing rollers 34 come into contact with different bill surfaces. For example, when the banknote is stored in the stacker and comes into contact with the two deposit removal rollers 34, the first deposit removal roller 34 comes into contact with one surface of the banknote and the second deposit Desirably, the removal roller 34 contacts the opposite surface of one side of the bill. Thereby, the deposit | attachment of both surfaces of a banknote can be removed.

Note that the banknote of the embodiment is an example of a paper sheet. In the embodiment, a paper sheet such as a ticket, a gift certificate, a check, or a slip may be used.
According to the apparatus of the embodiment, the substance adhering to the banknote can be removed. As a result, bills are less likely to be charged, and it is possible to prevent malfunction due to paper jam or electrostatic noise caused by charging.

  Moreover, since the substance adhering to the banknote can be removed, the banknote can be purified (recycled) at the same time.
