[0003] Patent Literature 1: Japanese Patent Application Laid-open No. 2008-210104SummaryTechnical Problem

[0004] In a shop, in order to prevent theft of banknotes, there is a case where a clerk takes out banknotes from a change machine and keeps these banknotes in a safe at the time of closing the shop. In this case, it is necessary to perform an operation of moving banknotes themselves taken out from a change machine to a collection bag or the like (a taking-out operation, a cash managing operation). However, for example, when there are many change machines in a shop, there are inconveniences that an excessive length of time is required for such operations. Accordingly, in order to prevent such inconveniences, it is conceivable to employ a configuration in which a storage part that collectively stores banknotes therein is provided in a change machine removably. According to this configuration, by detaching the storage part in a state of storing banknotes therein from a change machine and keeping the storage part in a safe, the operation of moving banknotes taken out from the change machine to a collection bag can be omitted.

[0005] However, in a configuration in which a storage part is provided in a change machine removably, when a plurality of change machines are provided in a shop, there is another problem that a storage part detached from one change machine is attached to another change machine. In consideration of such circumstances, an object of the present invention is to prevent inconveniences that a storage part detached from one paper sheet processing device is attached to another paper sheet processing device.Solution to Problem

[0006] In order to solve the above problems, a paper sheet processing device according to the present invention is a paper sheet processing device capable of receiving paper sheets, including a storage part that is capable of storing received paper sheets therein and capable of discharging stored paper sheets and a main body part including the storage part removably, wherein the main body part includes a memory part that memorizes therein identification information with which the storage part corresponding to the main body part is identifiable and storage information with which number of paper sheets stored in the storage part is specifiable.Advantageous Effects of Invention

[0007] According to the present invention, an object is to prevent inconveniences that, in a configuration in which a storage part is provided in a paper sheet processing device removably, there is an operation of moving banknotes to a collection bag and that a storage part detached from one paper sheet processing device is attached to another paper sheet processing device.Brief Description of Drawings

[0009] FIG. 1 is an external perspective view of a change machine 1 as an example of a paper sheet processing device. The change machine 1 is configured to be communicable with a POS control device 2 installed in a shop. Specifically, items purchased by a customer are registered in the POS control device 2. When all items are registered, a total sum (hereinafter, "purchased sum") of the prices of these items are output from the POS control device 2 to the change machine 1. When the purchased sum is input, the change machine 1 receives customer's banknotes and coins. When the total sum received from the customer (hereinafter, "received sum") reaches the purchased sum, this fact is transmitted to the POS control device 2.

[0010] As illustrated in FIG. 1, the change machine 1 is configured to include a banknote processing unit 100 and a coin processing unit 200. As illustrated in FIG. 1, a coin inlet 201 and a coin outlet 202 are provided on the coin processing unit 200. For example, customer's coins are fed in the coin inlet 201. Further, the coin outlet 202 can discharge coins as the change.

[0011] As illustrated in FIG. 1, a banknote inlet / outlet 101 is provided on the banknote processing unit 100. The banknote inlet / outlet 101 can take in customer's banknotes and can discharge banknotes as the change. Further, the banknote processing unit 100 is configured to include a casing 102. Storage units 104 described later are stored in the casing 102 (see FIG. 2(a)).

[0012] Banknotes taken in from the banknote inlet / outlet 101 of the banknote processing unit 100 are stored in the storage units 104 through a transport path 108 (see FIG. 2(b)) in the casing 102. Further, the banknote processing unit 100 can discharge banknotes stored in the storage units 104 from the banknote inlet / outlet 101 as the change. As the details thereof are described later, these storage units 104 are configured to be detachable with respect to the banknote processing unit 100 (a main body unit 103).

[0013] As illustrated in FIG. 1, a touch panel D and mode changing switches S are provided on the change machine 1. For example, the number of banknotes stored in the change machine 1 is displayed in each denomination on the touch panel D. The mode changing switches S are operated when the mode of the change machine 1 is switched. As the details thereof are described later, the change machine 1 is shifted to an operation mode, a management mode, and a maintenance mode. The operation mode is a mode in which banknotes and coins are received from a customer and the change can be paid out. The management mode is a mode in which banknotes stored in the change machine 1 can be managed. The maintenance mode is a mode in which the storage units 104 can be detached from the change machine 1.

[0014] Each of these mode changing switches S is constituted of a cylinder lock having a keyhole in which a key can be inserted. For example, when a key inserted in a mode changing switch S is turned to a first position, the change machine 1 is shifted to the operation mode. Similarly, when the key is turned to a second position, the change machine 1 is shifted to the management mode, and when the key is turned to a third position, the change machine 1 is shifted to the maintenance mode. In this configuration, by appropriately managing the keys for the mode changing switches S, inconveniences that the mode of the change machine 1 is wrongly changed are prevented. However, the configuration of switching the mode of the change machine 1 is not limited to the example described above. For example, it is possible to configure that the mode of the change machine 1 can be changed when a preset password is input.

[0015] FIG. 2(a) is an explanatory diagram of the interior of the banknote processing unit 100 (the casing 102) in the change machine 1. FIG. 2(a) is an A-A cross section of the banknote processing unit 100 in FIG. 1. As illustrated in FIG. 2(a), the main body unit 103, the storage units 104 (x, y) removably attached to the main body unit, and a collection cassette 107 are incorporated in the casing 102. As described above, the storage units 104 store therein banknotes that are discharged as the change. Further, the storage units 104 include a storage unit 104x and a storage unit 104y. As the details thereof are described later, between the storage unit 104x and the storage unit 104y, the denominations (A, B, C, D) of stored banknotes are different from each other.

[0016] The collection cassette 107 stores therein banknotes of denominations (E, F) that are not used as the change among banknotes taken in from the banknote inlet / outlet 101. That is, banknotes of denominations that are not stored in the storage units 104 are stored in the collection cassette 107. For example, large-denomination banknotes are assumed as the banknotes of denominations that are not used as the change.

[0017] As the details thereof are described later, in the present embodiment, as for the number of banknotes stored in the storage units 104, an upper limit number is set for each denomination of the relevant banknotes. There is assumed a case where banknotes of a denomination that are supposed to be stored in a storage units 104 are received, but banknotes of this denomination in this storage unit 104 are reaching its upper limit number. In this case, these banknotes are stored (overflowed) in the collection cassette 107 instead of in the storage units 104.

[0018] As illustrated in FIG. 2(a), the storage units 104 and the collection cassette 107 are provided in the main body unit 103. As the details thereof are described with reference to FIG. 2(c), the storage units 104 are arranged in the main body unit 103 removably. The storage units 104 are configured to be portable in a state of being detached from the main body unit 103. Further, the collection cassette 107 is arranged in the main body unit 103 removably. The collection cassette 107 is configured to be portable in a state of being detached from the main body unit 103.

[0019] A removable lid part 102a is provided on an upper opening of the casing 102. Further, a locking part L1 is provided in the main body unit 103. The storage units 104 can be detached from the main body unit 103 by opening the lid part 102a of the casing 102 and inserting a key in the locking part L1 to unlock it. Further, a locking part L2 is provided in the collection cassette 107. The collection cassette 107 can be detached from the main body unit 103 by opening the lid part 102a of the casing 102 and inserting a key in the locking part L2 to unlock it. The banknote inlet / outlet 101 is provided on the main body unit 103. Banknotes taken in from the banknote inlet / outlet 101 are stored in the storage units 104 or the collection cassette 107.

[0020] FIG. 2(b) is an explanatory diagram of a transport path of banknotes in the interior of the banknote processing unit 100. In FIG. 2(b), the casing 102 is not illustrated. As illustrated in FIG. 2(b), each of the storage units 104 of the present embodiment includes respective drums 106. Banknotes having been taken in the banknote inlet / outlet 101 are transported to any of the drums 106 (the storage units 104) corresponding to the denomination of the banknotes and rolled up (stored) by the relevant drums 106. Note that the storage units 104 are not limited to this specific example and can be changed as appropriate.

[0021] The banknote processing unit 100 of the present embodiment can receive banknotes of respective denominations including a denomination A, a denomination B, a denomination C, a denomination D, a denomination E, and a denomination F. As illustrated in FIG. 2(b), the storage unit 104x among the storage units 104 includes a drum 106a and a drum 106b. Further, the storage unit 104y includes a drum 106c and a drum 106d. Banknotes of the denominations (A to D) that are used as the change among respective banknotes received in the banknote processing unit 100 are stored in the drums (a to d) corresponding to the denominations of the received banknotes.

[0022] Specifically, banknotes of the denomination A among the banknotes that are used as the change are stored in the drum 106a and banknotes of the denomination B are stored in the drum 106b. That is, banknotes of the denomination A and the denomination B are stored in the storage unit 104x. Similarly, banknotes of the denomination C are stored in the drum 106c and banknotes of the denomination D are stored in the drum 106d. That is, banknotes of the denomination C and the denomination D are stored in the storage unit 104y.

[0023] Meanwhile, banknotes of the denomination E and banknotes of the denomination F that are not used as the change among the banknotes received in the banknote processing unit 100 are stored in the collection cassette 107. Note that in the present embodiment, an upper limit number is set for each drum 106 (each denomination). When banknotes stored in the drums 106 are reaching an upper limit number, even when these are banknotes of a denomination that are supposed to be stored in the relevant drum 106, these banknotes are stored in the collection cassette 107.

[0024] As illustrated in FIG. 2(b), the transport path 108 to which banknotes are transported is provided in the main body unit 103. The main body unit 103 includes an identification unit that identifies the denominations of banknotes taken in from the banknote inlet / outlet 101, and changes the route through which these banknotes are transported corresponding to the identified denominations. As the technology to identify denominations of banknotes and the technology to change the route through which banknotes are transported, for example, the technology described in Japanese Patent Publication No. 6505298 may be employed.

[0025] Specifically, when the denomination of banknotes taken in from the banknote inlet / outlet 101 is identified as the denomination A, a route through which the banknotes are transported from the banknote inlet / outlet 101 to the drum 106a of the storage unit 104x is formed. Note that, in a case where the banknotes in the drum 106a are reaching the upper limit number, when banknotes of the denomination A are taken in from the banknote inlet / outlet 101, a route through which the banknotes are transported from the banknote inlet / outlet 101 to the collection cassette 107 is formed. This is also true when banknotes of the denomination B, banknotes of the denomination C, or banknotes of the denomination D are taken in.

[0026] Further, when banknotes of the denomination E are taken in from the banknote inlet / outlet 101, the route is changed to a route through which the banknotes are transported from the banknote inlet / outlet 101 to the collection cassette 107. This is also true when banknotes of the denomination F are taken in from the banknote inlet / outlet 101. When banknotes of the denomination A are discharged from the banknote inlet / outlet 101, a route through which the banknotes are transported from the drum 106a to the banknote inlet / outlet 101 is formed. This is also true when banknotes of the denomination B, banknotes of the denomination C, or banknotes of the denomination D are discharged. In the present embodiment, while it is configured that banknotes once stored in the collection cassette 107 cannot be discharged from the banknote inlet / outlet 101, it is possible to configure that these banknotes can be discharged therefrom.

[0027] FIG. 2(c) is an explanatory diagram of the storage units 104 (x, y) and the collection cassette 107 having been detached from the main body unit 103. As illustrated in FIG. 2(c), among the storage units 104 (x, y), a connector 105x is provided on the storage unit 104x and a connector 105y is provided on the storage unit 104y. Further, connectors 111x and 111y are provided in the main unit body 103. When the storage unit 104x is attached to the main body unit 103, the connector 105x and the connector 111x are connected to each other. Further, when the storage unit 104y is attached to the main body unit 103, the connector 105y and the connector 111y are connected to each other.

[0028] As the details thereof are described later, individual memories 110 (x, y) are provided in the storage units 104 (x, y). Identification information ID for identifying the storage unit 104 in which a corresponding individual memory 110 is provided is memorized in these individual memories 110. Further, the main body unit 103 includes a control unit 109. When the connector 105 on the storage unit 104 and the connector 111 in the main body unit 103 are connected to each other, identification information ID memorized in the individual memory 110 of a corresponding storage unit 104 can be read by the control unit 109 of the main body unit 103. The control unit 109 determines whether an appropriate storage unit 104 has been attached based on the identification information ID.

[0029] The change machine 1 monitors whether the connector 111 in the main body unit 103 is connected to the connector 105 on the storage unit 104 and monitors whether the storage unit 104 is attached to the main body unit 103. In the present embodiment, a time when the collection cassette 107 is attached to the main body unit 103 and a time when it is detached therefrom are memorized in the change machine 1 (a main memory 115) as history information. Further, whether the collection cassette 107 is attached to the main body unit 103 is detected by a sensor and a time when the collection cassette 107 is attached thereto and a time when it is detached therefrom are memorized in the change machine 1 as history information.

[0030] FIG. 3(a)and FIG. 3(b) are specific examples of a banknote processing method. As described above, the change machine 1 is shifted to the operation mode, the management mode, and the operation mode. FIG. 3(a)is a specific example of a banknote processing method in the operation mode. For example, during business hours of a shop, the change machine 1 is shifted to the operation mode. As described above, in the operation mode, the change machine 1 receives customer's banknotes and discharges banknotes as the change.

[0031] Specifically, when banknotes (the denominations A to D) that are used as the change are received, these banknotes are stored in the storage unit 104 (the drum 106) (Sa1 in FIG. 3(a)). Further, banknotes in the storage unit 104 (the drum 106) are discharged as the change (Sa2 in FIG. 3(a)). When banknotes (the denominations E and F) that are not used as the change are received, these banknotes are stored in the collection cassette 107 (Sa3 in FIG. 3(a)). Even in a case where banknotes of denominations that are used as the change are received, when banknotes of these denominations stored in the storage unit 104 are reaching the upper limit number, the received banknotes are stored in the collection cassette 107 (Sa4 in FIG. 3(a)). As described above, the banknotes stored in the collection cassette 107 are not discharged (not returned).

[0032] FIG. 3(b) is an explanatory diagram of a specific example of a banknote processing method in the maintenance mode. As described above, in the maintenance mode, the collection cassette 107 can be detached. Specifically, the control unit 109 of the change machine 1 monitors whether the collection cassette 107 has been detached. When the collection cassette 107 is detached in modes other than the maintenance mode, the change machine 1 shifts to an error state. The time when the change machine 1 shifted to an error state is memorized as history information in the main memory 115. Similarly, as for the storage units 104, the change machine 1 also shifts to an error state when the storage units 104 are detached in modes other than the maintenance mode, and the time when the change machine 1 shifted to an error state is stored as history information in the main memory 115.

[0033] Meanwhile, the change machine 1 does not shift to an error state even when the collection cassette 107 is detached in the maintenance mode. Banknotes in this collection cassette 107 can be collected in a state where the collection cassette 107 is detached from the main body unit 103. For example, a clerk at a shop shifts the change machine 1 to the maintenance mode after closing the shop. In this case, after closing the shop, banknotes in the collection cassette 107 are taken out and these banknotes can be stored in a safe S (Sb1 in FIG. 3(b)). For example, the safe S is provided in a back room of the shop.

[0034] There is a possibility that banknotes in the collection cassette 107 are stolen even during business hours of a shop. Therefore, there is a case where it is preferable to take out banknotes in the collection cassette 107 to keep them in the safe S in the middle of business hours of the shop. In this case, a clerk at the shop shifts the change machine 1 to the maintenance mode in the middle of business hours and collects the banknotes in the collection cassette 107 (performs collection in the middle of business hours). As the details thereof are described later, the change machine 1 memorizes therein the number of banknotes in the collection cassette 107 in each denomination as collection information N (see FIG. 5). It is necessary to shift the change machine 1 to the management mode and to initialize the collection information N before collecting the banknotes in the collection cassette 107.

[0035] As described above, the storage unit 104 is portable in a state of storing banknotes therein. In the present embodiment described above, the storage unit 104 detached from the main body unit 103 can be stored in the safe S as it is without taking out the banknotes in the storage unit 104 (while the banknotes are left therein). Therefore, for example, as compared to a configuration in which it is necessary to take out all the banknotes in the storage unit 104 at the time of closing a shop, there is an advantage that the workload of clerks at the shop can be reduced. Further, for example, as compared to a configuration in which banknotes are left in the change machine 1 at the time of closing a shop, there is an advantage that the risk of banknotes that are used as the change are stolen is prevented.

[0036] Note that, in a configuration in which the storage unit 104 is detached from the change machine 1 at the time of closing a shop and is kept in the safe S, it is necessary to take out the storage unit 104 from the safe S at the time of opening the shop to attach it to the change machine 1. Further, there is a case where a plurality of change machines 1 are provided in a shop (for example, a large-scale shop). In this case, a plurality of storage units 104 detached from the plurality of change machines 1 are kept in the safe S.

[0037] When a plurality of change machines 1 are provided in a shop, normally the number of banknotes stored in each of the storage units 104 is mutually different in each of the change machines 1. Further, the number of banknotes stored in the storage unit 104 is memorized as storage information n on the main body unit 103 side of the change machine 1 (see FIG. 5). With this configuration, if the storage unit 104 is attached to another change machine 1 that is different from a change machine 1 to which the storage unit 104 is supposed to be attached, there may be inconveniences that the storage information n memorized in the wrong change machine 1 and the number of banknotes actually stored in the storage unit 104 do not match each other. In the present embodiment, such inconveniences are prevented by memorizing the identification information ID in the storage unit 104. This configuration is described later in detail.

[0038] FIG. 4 is a hardware configuration diagram of the change machine 1. As illustrated in FIG. 4, the change machine 1 includes the storage units 104 (x, y) and the collection cassette 107 described above. Further, the change machine 1 includes the connectors 111 (x, y) and the control unit 109. The connectors 111 and the control unit 109 are provided on the main body unit 103 side of the change machine 1.

[0039] The control unit 109 is configured to include a CPU (Central Processing Unit) 112, a ROM (Read Only Memory) 113, a RAM (Random Access Memory) 114, and the main memory 115. The ROM 113 memorizes therein various information in a nonvolatile manner. For example, the ROM 113 memorizes therein various information including programs. The CPU 112 executes programs memorized in the ROM 113. The RAM 114 can temporarily memorize various information therein. For example, the RAM 114 memorizes therein various information generated when the CPU 112 has executed a program.

[0040] For example, as the CPU 112 executes a program, a taking-in operation of banknotes from the banknote inlet / outlet 101 is realized. A banknote taken in from the banknote inlet / outlet 101 is detected by various sensors and a detection signal is input to the control unit 109. The control unit 109 determines the authenticity and the denomination of the banknote based on the detection signal. The control unit 109 generates a drive signal for driving a motor and a solenoid corresponding to the detection result of the banknote. According to this configuration, the banknote is transported to any of the storage units 104 (the drums 106a to 106d) or the collection cassette 107 of the change machine 1 and is stored therein. When any appropriate detection result is not obtained, a rejecting operation is performed and the banknote is discharged from the banknote inlet / outlet 101.

[0041] As the main memory 115, for example, a flash memory is preferably employed. While a flash memory is exemplified as the main memory 304, other types of memorizing means may be also employed. For example, an EEPROM may be employed as the main memory 304. Various information is memorized in the main memory 115 described above. For example, the main memory 115 memorizes therein the storage information n (a to d) representing the number of banknotes of each denomination stored in the storage units 104 (see FIG. 5 described later). Further, the main memory 115 memorizes therein the identification information ID for identifying the storage units 104. This identification information ID is given to each of the storage units 104.

[0042] For example, the identification information ID (IDx) is mutually different between respective storage units 104x detached from different change machines 1. Similarly, the identification information ID (IDy) is mutually different between respective storage units 104y detached from different change machines 1. Further, the identification information ID is mutually different between the storage unit 104x and the storage unit 104y even if these storage units belong to a common change machine 1. The identification information ID is used when whether the storage units 104 attached to the change machine 1 are appropriate is determined.

[0043] As illustrated in FIG. 4, the storage unit 104 (x, y) includes the drums 106 (a, b, c, d), the connector 105 (x, y), and the individual memory 110 (x, y). Specifically, as described above, the drum 106a in which banknotes of the denomination A are stored and the drum 106b in which banknotes of the denomination B are stored are provided in the storage unit 104x among the storage units 104. As described above, the drum 106c in which banknotes of the denomination C are stored and the drum 106d in which banknotes of the denomination D are stored are provided in the storage unit 104y among the storage units 104.

[0044] The connectors 105 include the connector 105x provided in the storage unit 104x and the connector 105y provided in the storage unit 104y among the storage units 104. As described above, when the storage unit 104x is attached to the change machine 1 (the main body unit 103), the connector 105x in the storage unit 104x is connected to the connector 111x in the main body unit 103. Similarly, when the storage unit 104y is attached to the change machine 1, the connector 105y in the storage unit 104y is connected to the connector 111y in the main body unit 103.

[0045] The individual memories 110 include the individual memory 110x provided in the storage unit 104x and the individual memory 110y provided in the storage unit 104y among the storage units 104. In each of the individual memories 110 (x, y), information including the identification information ID for identifying the storage unit 104 in which the corresponding individual memory 110 is provided is memorized in a nonvolatile manner. The information of this individual memory 110 can be read by the control unit 109 in a state where the connector 105 on the storage unit 104 in which the corresponding individual memory 110 is provided is connected to the connector 111 in the main body unit 103.

[0046] FIG. 5 is an explanatory diagram of a specific example of each information memorized in the main memory 115 and the individual memories 110 (x, y). As illustrated in FIG. 5, various information including first unit information Dx, second unit information Dy, and the collection information N is memorized in the main memory 115 (the main body unit 103 side). Each information in the main memory 115 is updated by the control unit 109.

[0047] The first unit information Dx is various information related to the storage unit 104x among the storage units 104 (x, y). Specifically, the first unit information Dx includes identification information IDx of the storage unit 104x, storage information na representing the number of banknotes (the denomination A) stored in the drum 106a, storage information nb representing the number of banknotes (the denomination B) stored in the drum 106b, an upper limit number La of the banknotes stored in the drum 106a, and an upper limit number Lb of the banknotes stored in the drum 106b. The specific example in FIG. 5 assumes a case where 19 banknotes of the denomination A are stored in the drum 106a and 30 banknotes of the denomination B are stored in the drum 106b.

[0048] The second unit information Dy is various information related to the storage unit 104y among the storage units 104 (x, y). Specifically, the second unit information Dy includes identification information IDy of the storage unit 104y, storage information nc representing the number of banknotes (the denomination C) stored in the drum 106c, storage information nd representing the number of banknotes (the denomination D) stored in the drum 106d, an upper limit number Lc of the banknotes stored in the drum 106c, and an upper limit number Ld of the banknotes stored in the drum 106d. The specific example in FIG. 5 assumes a case where one banknote of the denomination C is stored in the drum 106c and 17 banknotes of the denomination D are stored in the drum 106d.

[0049] When banknotes are stored in the drums 106 (a to d) of the change machine 1, the storage information n corresponding to the relevant drum 106 is added. For example, when one banknote (the denomination A) is stored in the drum 106a, a value "1" is added to the storage information na among the respective pieces of the storage information n. Further, when banknotes are discharged as the change from the drum 106 of the change machine 1, the storage information n corresponding to the relevant drum 106 is subtracted. For example, when one banknote (the denomination A) is discharged from the drum 106a, a value "1" is subtracted from the storage information na among the respective pieces of the storage information n.

[0050] The upper limit number L (a to d) of banknotes stored in each drum 106 (a to d) can be changed in the management mode. That is, in the present embodiment, the upper limit number of banknotes left in the change machine 1 for the next day as the change can be changed for each denomination. For example, the numbers of banknotes necessary for the change may be different according to the scale of shop. Further, there are circumstances that an amount of change more than necessary should not be left in the change machine 1 in order to reduce the risk of theft. By appropriately adjusting the upper limit number L for each drum 106, there is an advantage that the risk of theft can be reduced while leaving a necessary amount of change.

[0051] The collection information N (a to f) among respective pieces of information memorized in the main memory 115 represents the number of banknotes stored in the collection cassette 107. Specifically, the collection information N includes collection information Na representing the number of banknotes of the denomination A, collection information Nb representing the number of banknotes of the denomination B, collection information Nc representing the number of banknotes of the denomination C, collection information Nd representing the number of banknotes of the denomination D, collection information Ne representing the number of banknotes of the denomination E, and collection information Nf representing the number of banknotes of the denomination F, where these banknotes are stored in the collection cassette 107.

[0052] For example, when a banknote of the denomination E that is not used as the change is received, this banknote is stored in the collection cassette 107 and a value "1" is added to the collection information Ne among the respective pieces of the collection information N. Further, in a case where banknotes of the denominations (A to D) that are used as the change are received and the storage information n (a to d) of the relevant denominations is reaching the upper limit number L (a to d), these banknotes are stored in the collection cassette 107. In this case, addition is made to the collection information N (a to d) representing the number of banknotes of the denominations (A to D) that are used as the change. As described above, banknotes in the collection cassette 107 are not discharged as the change. Therefore, the collection information N is not subtracted in principle. However, as described later, when the banknotes in the collection cassette 107 are collected, the collection information N (a to f) is initialized as a value "0".

[0053] As illustrated in FIG. 5, the individual memory 110x in the storage unit 104x memorizes therein the identification information IDx for identifying this storage unit 104x. As described above, when the storage unit 104 (the connector 105) is connected to the connector 111x in the main body unit 103, the control unit 109 determines whether the identification information ID memorized in the individual memory 110 in the relevant storage unit 104 is appropriate.

[0054] Specifically, when the storage unit 104 is connected to the connector 111x, whether the identification information ID memorized in the individual memory 110 in this storage unit 104 matches the identification information IDx memorized in the main memory 115 of the control unit 109 is determined automatically. If the storage unit 104x detached from a change machine 1 other than the change machine 1 the storage unit 104x is supposed to be detached from is attached to the connector 111x, the above determination result becomes mismatch. Further, when the storage unit 104y is connected to the connector 111x (instead of the connector 111y), the determination result becomes mismatch.

[0055] Similarly, the individual memory 110y in the storage unit 104y memorizes therein the identification information IDy for identifying this storage unit 104y. As described above, when the storage unit 104 (the connector 105) is connected to the connector 111y in the main body unit 103, the control unit 109 determines whether the identification information ID memorized in the individual memory 110 in the relevant storage unit 104 is appropriate.

[0056] Specifically, when the storage unit 104 is connected to the connector 111y, whether the identification information ID memorized in the individual memory 110 in this storage unit 104 matches the identification information IDy stored in the main memory 115 of the control unit 109 is determined automatically. If the storage unit 104y detached from a change machine other than the change machine the storage unit 104y is supposed to be detached from is attached to the connector 111y, the determination result becomes mismatch. Further, when the storage unit 104x is connected to the connector 111y (instead of the connector 111x), the determination result becomes mismatch.

[0057] FIG. 6 is a functional block diagram of a banknote processing device 10. For example, as the CPU 112 described above executes a program, the change machine 1 functions as the banknote processing device 10. As illustrated in FIG. 6, the banknote processing device 10 includes a main body part 11, a storage part 12x, a storage part 12y, and a collection part 13.

[0058] The storage parts 12 (x, y) can store therein banknotes received by the banknote processing device 10 and can discharge stored banknotes. The storage parts 12 of the present embodiment include the storage part 12x and the storage part 12y. For example, the storage unit 104x described above functions as the storage part 12x and the storage unit 104y described above functions as the storage part 12y. As illustrated in FIG. 6, each of the storage parts 12 memorizes therein the identification information ID for identifying the relevant storage part 12.

[0059] The storage part 12x among the storage parts 12 stores therein banknotes of the denomination A and banknotes of the denomination B among the banknotes received in the banknote processing device 10. Further, the storage part 12y stores therein banknotes of the denomination C and banknotes of the denomination D among the banknotes received in the banknote processing device 10. While the banknote processing device 10 of the present embodiment includes two storage parts 12, the number of the storage parts 12 can be changed as appropriate. For example, one storage part 12 or three or more storage parts 12 may be provided in the banknote processing device 10.

[0060] During a period where the number of banknotes in the storage parts 12 is reaching the upper limit number L, the collection part 13 stores therein received banknotes. For example, the collection cassette 107 described above functions as the collection part 13. Further, when banknotes of the denomination E or banknotes of the denomination F that are not used as the change are received in the banknote processing device 10, the banknotes of these denominations are stored in the collection part 13.

[0061] The main body part 11 includes the storage parts 12 (x, y) and the collection part 13 detachably. For example, the main body unit 103 described above functions as the main body part 11. As illustrated in FIG. 6, the main body part 11 is configured to include a memory part 14 and a control part 15. For example, the main memory 115 described above functions as the memory part 14. Further, the CPU 112 described above functions as the control part 15.

[0062] The memory part 14 in the main body part 11 memorizes therein the identification information ID with which the storage part 12 corresponding to this main body part 11 is identifiable and the storage information n (a to d) with which the number of banknotes stored in the relevant storage part 12 is specifiable. Further, the memory part 14 memorizes therein the collection information N representing the number of banknotes having been stored in the collection part 13 for each denomination (A to D) and each upper limit number L (a to d) of banknotes of each denomination (A to D) to be stored in the storage part 12. In the present embodiment, during a period from closing and opening a shop, even when power supply to the banknote processing device 10 is shut down, each information in the memory part 14 is maintained.

[0063] The control part 15 in the main body part 11 includes a changing part 16, an initializing part 17, and a shifting part 18. The changing part 16 can change the upper limit number L memorized in the memory part 14. Specifically, the changing part 16 can change the upper limit number L for each denomination. In the present embodiment, any value from a range of "0 to 100" is set as the upper limit number L. The value range settable as the upper limit number L can be changed as appropriate according to the storage capacity of the storage parts 12 (drums), for example.

[0064] The shifting part 18 shifts to the management mode set in advance. Specifically, the shifting part 18 shifts to any of the management mode, the operation mode, and the maintenance mode when the mode changing switches S are operated appropriately. The initializing part 17 can initialize the collection information N (a to f) representing the number of banknotes stored in the collection part 13 in the management mode.

[0065] As an example, there is assumed a configuration in which the storage information n and the collection information N are both initialized uniformly (hereinafter, "comparative example"). Further, there is assumed a case where, among the respective banknotes in the storage parts 12 and the collection part 13, at the time of closing a shop, the banknotes in the storage parts 12 are left therein and the banknotes in the collection part 13 are collected. In this case, in the above comparative example, the storage information n is initialized although banknotes are left in the storage parts 12. Therefore, in the above comparative example, there occurs inconveniences that the number of banknotes actually stored in the storage parts 12 and the number of banknotes represented by the storage information n do not match each other. According to the initializing part 17 of the present embodiment, since the storage information n can be maintained while initializing the collection information N, such inconveniences can be prevented.

[0066] As described above, the banknote processing device 10 includes a display part 19. For example, the touch panel D described above functions as the display part 19. The display part 19 displays various information. For example, the display part 19 displays the current value of the storage information n (see Go in FIG. 8 described later). Further, the display part 19 displays the current value of the collection information N (see Gc in FIG. 8 described later). This display part 19 is configured to be able to accept touch operations. Each image displayed on the display part 19 is described later with reference to FIG. 8.

[0067] FIG. 7 is an explanatory diagram of a specific example where banknotes are left in the storage part 12x. As described above, banknotes of the denomination A and banknotes of the denomination B are stored in the storage part 12x. In the specific example in FIG. 7, a case where banknotes of the denomination A and banknotes of the denomination B are left in the storage part 12x is described. Further, there is assumed a case where, at the time of closing a shop, the storage part 12x is detached from the banknote processing device 10 and stored in the safe S. In FIG. 7, the storage part 12y is not illustrated. Banknotes in the storage part 12y can be processed similarly to the banknotes in the storage part 12x.

[0068] Specifically, in FIG. 7, there is assumed a case where, at the time of closing a shop, storage parts 12x are detached from a plurality of banknote processing devices 10 and the plurality of storage parts 12x are stored in the safe S. In the following descriptions, for the sake of explanation, one of the plurality of banknote processing devices 10 is described as "banknote processing device 10v" and another one is described as "banknote processing device 10w". Further, the storage part 12x of the banknote processing device 10v is described as "storage part 12xv" and the storage part 12x of the banknote processing device 10w is described as "storage part 12xw". Similarly, the memory part 14 of the banknote processing device 10v is described as "memory part 14v" and the memory part 14 of the banknote processing device 10w is described as "memory part 14w". Further, in FIG. 7, a portion (na, nb, IDx) of each information memorized in the memory part 14v (the main body part side) of each banknote processing device 10v is illustrated. Similarly, a portion (na, nb, IDx) of each information memorized in the memory part 14w of each banknote processing device 10w is illustrated.

[0069] In FIG. 7, the number of banknotes of the denomination A and the number of banknotes of the denomination B stored in the storage units 12x (v, w) are illustrated. In the specific example in FIG. 7, there is assumed a case where n1 banknotes of the denomination A and n2 banknotes of the denomination B are stored in the storage part 12xv. That is, there is assumed a case where, at the time of closing a shop, n1 banknotes of the denomination A and n2 banknotes of the denomination B are stored in the banknote processing device 10v. In this case, the storage information na (the number of banknotes of the denomination A) memorized in the memory part 14v of the banknote processing device 10v is "n1" (na=n1). Similarly, the storage information nb (the number of banknotes of the denomination B) memorized in the memory part 14v of the banknote processing device 10v is "n2" (nb=n2).

[0070] Further, in the specific example in FIG. 7, there is assumed a case where m1 (where m1≠n1) banknotes of the denomination A are stored in the storage part 12xw. That is, there is assumed a case where, at the time of closing a shop, m1 banknotes of the denomination A are stored in the banknote processing device 10w. In this case, the storage information na (the number of banknotes of the denomination A) memorized in the memory part 14w of the banknote processing device 10w is "m1" (na=m1). Further, there is assumed a case where, at the time of closing a shop, m2 banknotes of the denomination B are stored in the banknote processing device 10w. In this case, the storage information nb (the number of banknotes of the denomination B) memorized in the memory part 14w of the banknote processing device 10w is "m2" (nb=m2).

[0071] At the time of opening a shop, a clerk at the shop takes out each storage part 12 from the safe S and attaches these storage parts 12 to respective banknote processing devices 10. Note that banknotes stored in the storage parts 12 are left therein since the time of closing the shop. Further, the storage information n representing the number of banknotes stored in the storage parts 12 at the time of closing the shop is memorized in the memory part 14 (the main body part 11 side). Therefore, in order to match the number of banknotes actually stored in the storage parts 12 and the number of banknotes represented by the storage information n in the memory part 14, it is necessary that the storage parts 12 detached from the banknote processing devices 10 at the time of closing the shop are attached to the same banknote processing devices 10 at the time of opening the shop. For example, in the specific example in FIG. 7, it is necessary that the storage part 12xv detached from the banknote processing device 10v at the time of closing the shop is attached to the banknote processing device 10v and not to the banknote processing device 10w.

[0072] Meanwhile, for example, in a shop where a larger number of banknote processing devices 10 are installed, the number of storage parts 12 stored in the safe S at the time of closing the shop is larger. When there is a large number of storage parts 12 stored in the safe S, there are circumstances that inconveniences that storage parts 12 detached at the time of closing the shop are attached to wrong banknote processing devices 10 at the time of opening the shop. In consideration of such circumstances, in the present embodiment, a configuration to prevent such inconveniences is employed.

[0073] Specifically, the storage part 12 of the present embodiment memorizes therein identification information ID specific to this storage part 12. Further, in the memory part 14 (the main body part 11 side) of the banknote processing device 10, identification information ID of the storage part 12 that is supposed to be attached to this banknote processing device 10 is memorized. For example, in the specific example in FIG. 7, identification information IDxv is memorized in the storage part 12xv having been detached from the banknote processing device 10v. Further, the identification information IDxv is memorized in the memory part 14v of the banknote processing device 10v. Similarly, identification information IDxw is memorized in the storage part 12xw having been detached from the banknote processing device 10w (IDxv≠IDxw). Further, the identification information IDxw is memorized in the memory part 14w of the banknote processing device 10w.

[0074] Upon attachment of the storage part 12, the banknote processing device 10 of the present embodiment automatically reads the identification information ID from this storage part 12. Further, the banknote processing device 10 determines whether the identification information ID memorized in the memory part 14 matches the identification information ID of the storage part 12. If the identification information ID of the storage part 12 matches the identification information ID in the memory part 14 (the main body part 11 side) (for example, Sc1 in FIG. 7), the banknote processing device 10 does not shift to an attachment error state.

[0075] On the other hand, when the identification information ID of the storage part 12 and the identification information ID in the memory part 14 (the main body part 11 side) do not match each other (for example, Sc2 in FIG. 7), the banknote processing device 10 shifts to an attachment error state. In the attachment error state, for example, a fact that an inappropriate storage part 12 is attached is notified. Specifically, a message indicating that an inappropriate storage part 12 is attached is displayed on the display part 19. According to this configuration, inconveniences that the storage part 12 detached from the banknote processing device 10 at the time of closing a shop is attached to a wrong banknote processing device 10 at the time of opening the shop are prevented.

[0076] FIG. 8 is an explanatory diagram of respective images (Go, Gm, Gc, Gh) displayed on the display part 19. As described above, the banknote processing device 10 shifts to the operation mode, the management mode, and the maintenance mode. In FIG. 8, simulated diagrams of an operation mode image Go displayed in the operation mode, a management mode image Gm displayed in the management mode, a collection information image Gc, and a during-replenishment image Gh are illustrated.

[0077] As illustrated in FIG. 8, the operation mode image Go displays the number of banknotes stored in the storage part 12 of the banknote processing device 10 for each denomination. That is, the operation mode image Go displays the number of remaining banknotes dischargeable as the change for each denomination. In the specific example in FIG. 8, there is assumed a case where 19 banknotes of the denomination A, 30 banknotes of the denomination B, 1 banknote of the denomination C, and 17 banknotes of the denomination D are stored in the storage part 12.

[0078] In the present embodiment, in the operation mode image Go, a notification corresponding to the number of remaining banknotes stored in the storage part 12 is made. For example, when the number of remaining banknotes in the storage part 12 is small, the fact is notified. As described above, the banknote processing device 10 memorizes therein the storage information n (a to d) representing the number of remaining banknotes of respective denominations (A to D) in the storage part 12. During a period where the storage information n is within a range of "0 to 5", the banknote processing device 10 displays the number of remaining banknotes of a denomination corresponding to the relevant storage information n in a unique mode (orange).

[0079] In the specific example in FIG. 8, there is assumed a case where the number of remaining banknotes of the denomination C is five or less (one). That is, a case where the value of the storage information nc is "5" or less is assumed. In this case, in the operation mode image Go, the number of remaining banknotes of the denomination C is displayed in orange. As the details thereof are described later, when the number of remaining banknotes in the storage part 12 is small, banknotes are replenished in the storage part 12 with a replenishment operation. In the present embodiment, since a fact that the number of remaining banknotes in the storage part 12 is small is notified, it is easier to avoid a situation where banknotes dischargeable as the change run short beforehand.

[0080] Further, the maximum number of banknotes that can be stored in the storage part 12 is set in advance for each denomination (for each drum 106). When the number of banknotes stored in the storage part 12 approaches the maximum number, a near-full notification is made in the operation mode image Go. Specifically, when the storage information n representing the number of banknotes stored in the storage part 12 approaches the maximum number (for example, when it is "maximum number - n≤5"), the number of banknotes of a denomination corresponding to this storage information n is displayed in the operation mode image Go in a unique mode. Note that when an optional upper limit number L is set, the near-full notification described above is not made.

[0081] As illustrated in FIG. 8, when the mode changing switches S are operated in the operation mode, the management mode image Gm is displayed instead of the operation mode image Go. Similarly to the operation mode image Go, the management mode image Gm displays the number of banknotes stored in the storage part 12. Further, the management mode image Gm displays a replenishment button B 1, a collection button B2, a payment button B3, and a cassette display button B4. For example, the payment button B3 is operated when banknotes are paid out to a customer. Specifically, when a touch operation is performed on the payment button B3, the number of banknotes discharged from the storage part 12 can be set for each denomination. Further, a set number of banknotes are discharged from the banknote processing device 10 (the banknote inlet / outlet 101), and the storage information n is subtracted corresponding to the number of discharged banknotes.

[0082] When a touch operation is performed on the cassette display button B4 in the management mode image Gm, the collection information image Gc is displayed. The collection information image Gc displays the number of banknotes stored in the collection part 13 for each denomination. Specifically, the banknote processing device 10 displays the number of banknotes of respective denominations (A to F) stored in the collection part 13 based on the collection information N (a to f) memorized in the memory part 14. Further, a total sum stored in the collection part 13 is displayed in the collection information image Gc. The total sum stored in the collection part 13 is calculated based on the collection information N.

[0083] In the specific example in FIG. 8, there is assumed a case where 3 banknotes of the denomination A, 23 banknotes of the denomination E, and 30 banknotes of the denomination F are stored in the collection part 13 and any banknote of other denominations (B to D) is not stored therein. As described above, in principle, banknotes of the denominations (A to D) that are used as the change are stored in the storage parts 12. However, in a state where banknotes of the denominations (A to D) that are used as the change are stored up to the upper limit number L in the storage parts 12, but banknotes of these denominations are newly received, the received banknotes are stored (overflowed) in the collection part 13. In the specific example in FIG. 8, a case where three banknotes of the denomination A are overflowed is assumed.

[0084] The collection information image Gc described above is displayed at an appropriate timing. For example, the collection information image Gc is displayed at the time of opening or closing a shop to confirm the number of banknotes stored in the collection part 13. If there are banknotes left in the collection part 13 at the time of opening or closing the shop, a clerk at the shop collects the banknotes from the collection part 13 and stores them in a safe S. Further, the collection information image Gc is displayed during business hours of the shop to confirm the number of banknotes stored in the collection part 13. If a large sum of banknotes is stored in the collection part 13 during business hours of the shop, a clerk at the shop collects the banknotes from the collection part 13 and stores them in a safe S (collects banknotes in the middle of business hours).

[0085] As the details thereof are described later, when banknotes in the collection part 13 are collected, it is necessary to initialize the collection information N. Specifically, as illustrated in FIG. 8, a selection image Gs is displayed when a touch operation is performed on the collection button B2 in the management mode image Gm. A collection image Gc is displayed through this selection image Gs (see FIG. 9 described later). When a touch operation is appropriately performed with respect to the collection image Gc, the collection information N is initialized. When an end button B5 in the collection information image Gc is operated, the management mode image Gm is displayed instead of the collection information image Gc.

[0086] As illustrated in FIG. 8, when a touch operation is performed on the replenishment button B1 in the management mode image Gm, the during-replenishment image Gh is displayed. During a period where the during-replenishment image Gh is displayed, banknotes that are used as the change can be replenished in the storage parts 12. For example, at the time of opening a shop, when the number of banknotes in the storage parts 12 is small, banknotes are replenished through the during-replenishment image Gh. Further, as described above, in the operation mode image Go, there is a case where a notification is made regarding banknotes of a small remaining number among banknotes of respective denominations in the storage parts 12. In this case, banknotes are replenished in the storage part 12 during business hours of the shop.

[0087] The end button B5, a start button B6, and a stop button B7 are displayed in the during-replenishment image Gh. When a touch operation is performed on the start button B6, taking-in of banknotes from the banknote inlet / outlet 101 is started. Specifically, the banknote inlet / outlet 101 is formed such that the top edge of a banknote bundle can be inserted therein. When a touch operation is performed on the start button B6 in a state where the top edge of a banknote bundle is inserted in the banknote inlet / outlet 101, the banknotes of this banknote bundle are taken in the banknote processing device 10 one by one. When a touch operation is performed on the stop button B7 during a period where this taking-in operation is performed, this taking-in operation is stopped.

[0088] As illustrated in FIG. 8, the number of banknotes replenished for each denomination is displayed in the during-replenishment image Gh. In the specific example in FIG. 8, a case where ten banknotes of the denomination C are replenished. Further, a total sum of replenished banknotes is displayed in the during-replenishment image Gh. When a touch operation is performed on the end button B5 in the during-replenishment image Gh, the management mode image Gm is displayed instead of the during-replenishment image Gh. As described above, the upper limit number L is set for each denomination with respect to the number of banknotes to be stored in the storage parts 12. If it is a case where banknotes are taken in due to a touch operation on the during-replenishment image Gh (B6) but the storage information n of banknotes of the relevant denomination is reaching the upper limit number L, the taken banknotes are discharged from the banknote inlet / outlet 101.

[0089] FIG. 9 is an explanatory diagram of respective images displayed when banknotes are collected from the banknote processing device 10. A simulated diagram of the selection image Gs, a simulated diagram of the collection image Gc, and a simulated diagram of a denomination specifying image Gd are illustrated in FIG. 9.

[0090] As described with reference to FIG. 8, the selection image Gs in FIG. 9 is displayed when a touch operation is performed on the collection button B2 in the management mode image Gm. The selection image Gs is an image in which banknotes to be collected from the banknote processing device 10 (the storage parts 12, the collection part 13) can be selected. Specifically, the selection image Gs displays the end button B5, a cassette collection button B8, a denomination specifying button B9, a number-of-banknotes specifying button B10, and a total collection button B11. For example, a touch operation is performed on the cassette collection button B8 when banknotes stored in the collection part 13 at present are collected.

[0091] The collection image Gc in FIG. 9 is displayed when a touch operation on the cassette collection button B8 in the selection image Gs is performed. The end button B5 and an initialization button B12 are displayed in the collection image Gc. When a touch operation is performed on the initialization button B12, the collection information N is initialized. Specifically, the collection information N includes collection information Na representing the number of banknotes of the denomination A, collection information Nb representing the number of banknotes of the denomination B, collection information Nc representing the number of banknotes of the denomination C, collection information Nd representing the number of banknotes of the denomination D, collection information Ne representing the number of banknotes of the denomination E, and collection information Nf representing the number of banknotes of the denomination F, where these banknotes are stored in the collection part 13. When a touch operation is performed on the initialization button B12, the collection information N (a to f) is initialized as a value "0".

[0092] When the collection information N is initialized, before shifting to the operation mode, it is necessary to take out banknotes in the collection part 13. If the banknotes in the collection part 13 are not taken out after initializing the collection information N, the number of banknotes represented by the collection information N and the number of banknotes actually stored in the collection part 13 do not match each other. For example, a clerk at a shop shifts the banknote processing device 10 to the maintenance mode after the collection information N is initialized, and detaches the collection part 13 to take out banknotes therein.

[0093] As illustrated in FIG. 9, when a touch operation is performed on the denomination specifying button B9, the denomination specifying image Gd is displayed. A touch operation is performed on the denomination specifying button B9 in the selection image Gs when banknotes stored in the collection part 13 at present as well as a portion (or all) of banknotes in the storage parts 12 are collected. As illustrated in FIG. 9, the denomination specifying image Gd displays a denomination button B13 corresponding to the denomination A, a denomination button B14 corresponding to the denomination B, a denomination button B 15 corresponding to the denomination C, a denomination button B16 corresponding to the denomination D, and a start button B17. When a touch operation is performed on the denomination buttons B (13 to 16), a denomination corresponding to the relevant denomination button B is selected.

[0094] When a touch operation is performed on the start button B17 after selecting a denomination with the denomination buttons B (13 to 16), banknotes of the selected denomination are transported from the storage parts 12 to the collection part 13. Further, the banknote processing device 10 initializes the storage information n (a to d) representing the number of banknotes having been transported from the storage parts 12 to the collection part 13 as a value "0". Further, the collection information N is updated according to the banknotes stored in the collection part 13. After transporting banknotes in the storage parts 12 to the collection part 13 due to operating the denomination specifying button B9 (the start button B17), a clerk at a shop initializes the collection information N using the collection image Gc described above, and then collects the banknotes in the collection part 13. In the present embodiment, when a touch operation is performed on the start button B17 after selecting a plurality of denomination buttons B, banknotes of plural types of denominations can be collected in the collection part 13 all at once.

[0095] The number-of-banknotes specifying button B10 is operated when a specified number of banknotes are collected from the storage parts 12. Specifically, when the number-of-banknotes specifying button B10 is operated, a number-of-banknotes specifying image in which the number of banknotes can be specified for each denomination is displayed. The number-of-banknotes specifying image is an image in which the number of banknotes to be collected can be input for each denomination. When the number of banknotes is specified using the number-of-banknotes specifying image, the specified number of banknotes are discharged from the banknote inlet / outlet 101. Further, the storage information n in the memory part 14 is updated according to the number of discharged banknotes. According to this number-of-banknotes specifying image, banknotes in the storage parts 12 can be collected without detaching the collection part 13. Note that it is also possible to configure that banknotes of a number specified by the number-of-banknotes specifying image are transported to the collection part 13.

[0096] The total collection button B11 is operated when all banknotes are collected from the banknote processing device 10. Specifically, when the total collection button B11 is operated, all banknotes stored in the storage parts 12 are transported to the collection part 13. After all banknotes are transported to the collection part 13, a clerk at a shop initializes the collection information N using the collection image Gc described above, and then collects the banknotes in the collection part 13.

[0097] FIG. 10(a) is a flowchart of a banknote storing process in the banknote processing device 10. The banknote processing device 10 performs the banknote storing process when banknotes are stored in the storage parts 12 or the collection part 13. Specifically, when banknotes are inserted from the banknote inlet / outlet 101, the banknote storing process is performed. As the technology to transport banknotes from the banknote inlet / outlet 101 to the storage parts 12 or the collection part 13, the technology described in, for example, Japanese Patent Publication No. 6505298 may be employed.

[0098] When a banknote is taken in from the banknote inlet / outlet 101, the banknote processing device 10 identifies the denomination of the banknote (S100). Specifically, the denomination of the banknote is identified based on a detection signal from a sensor provided in the transport path 108 (see FIG. 2(b)). Thereafter, the banknote processing device 10 determines whether the denomination of the taken banknote is any of the denomination A to the denomination D (S101). That is, the banknote processing device 10 determines whether the taken banknote is a banknote that is used as the change.

[0099] When it is determined that the banknote is not one that is used as the change (the banknote is of the denomination E or the denomination F) (S101: No), the banknote processing device 10 transports the banknote to the collection part 13 and stores it therein (S102). Further, the banknote processing device 10 updates (adds) the collection information N corresponding to the denomination of the banknote stored in the collection part 13 (S103). For example, when a banknote of the denomination E is stored in the collection part 13, a value "1" is added to the collection information Ne among the collection information N. In the present embodiment, the collection information N is updated after completing the operation of storing banknotes in the collection part 13. Therefore, if a banknote is jammed in the middle of the transport path 108 to the collection part 13, the collection information N is not updated. In this case, after removing the banknote from the transport path 108, this banknote is inserted in the banknote inlet / outlet 101 again.

[0100] On the other hand, when a banknote of the denomination (A to D) that is used as the change is taken in (S101: Yes), the banknote processing device 10 determines whether the storage information n (a to d) corresponding to the relevant denomination is equal to or more than the upper limit number L (a to d) (S104). That is, it is determined whether up to the upper limit number L of banknotes of a denomination matching the denomination of the newly taken banknote are already stored in the storage parts 12. For example, when a banknote of the denomination A is taken in, the banknote processing device 10 determines whether the storage information na representing the number of banknotes of the denomination A stored in the storage parts 12 is reaching the upper limit number La.

[0101] When the storage information n corresponding to the denomination of the taken banknote is not reaching the upper limit number L (S104: No), the banknote processing device 10 stores this banknote in the storage parts 12 (S105). Specifically, banknotes of the denomination A and banknotes of the denomination B are stored in the storage part 12x and banknotes of the denomination C and banknotes of the denomination D are stored in the storage part 12y. When banknotes are stored in the storage parts 12, the banknote processing device 10 updates the storage information n (adds a value "1") corresponding to the denomination of the relevant banknote (S106) and ends the banknote storing process.

[0102] When the storage information n corresponding to the denomination of the taken banknote is reaching the upper limit number L (S104: Yes), the banknote processing device 10 stores this banknote in the collection part 13. Further, the banknote processing device 10 updates the collection information N corresponding to the denomination of this banknote. After updating the collection information N, the banknote processing device 10 ends the banknote storing process. For example, when banknotes of the denomination A are stored in the collection part 13 (when banknotes of the denomination A are overflowed), a value "1" is added to the collection information Na.

[0103] FIG. 10(b) is a flowchart of an attaching time process performed by the banknote processing device 10. The attaching time process is performed to determine whether an appropriate storage part 12 is attached to the banknote processing device 10 (the main body part 11). As illustrated in FIG. 10(b), when the attaching time process is started, the banknote processing device 10 determines whether the timing is right after turning the power on (S110). Specifically, the banknote processing device 10 performs the attaching time process at a predetermined cycle during a period where power is supplied thereto. At Step S110, whether it is the first attaching time process since turning the power on is determined.

[0104] When it is determined that the timing is right after turning the power on (S110: Yes), the banknote processing device 10 performs processes at Step S112 and the following steps to determine whether an appropriate storage part 12 is attached to the banknote processing device 10. According to this configuration, there is an advantage that, even if a storage part 12 is attached to the banknote processing device 10 during a period where the power is shut down, the appropriateness of this storage part 12 is determined.

[0105] When it is determined that the timing is not right after turning the power on (S110: No), the banknote processing device 10 determines whether a storage part 12 is newly attached to the main body part 11 (S111). Specifically, when a storage part 12 is attached to the main body part 11 of the banknote processing device 10, the connector (110) of this storage part 12 is connected to the connector (111) of the main body part 11. The banknote processing device 10 monitors whether the respective connectors are connected to each other. When a state where the respective connectors are not connected to each other is changed to a state where they are connected to each other, it is determined that a storage part 12 is newly attached to the banknote processing device 10.

[0106] When it is determined that any storage part 12 is not newly attached to the banknote processing device 10 (S111: No), the banknote processing device 10 ends the attaching time process. As a case where it is determined as "No" at Step S111 described above, a case of a state where the storage part 12 is detached from the main body part 11 or a case where a state in which the storage part 12 is attached to the main body part 11 is continuing is assumed.

[0107] On the other hand, when it is determined that a storage part 12 is newly attached to the banknote processing device 10 (S111: Yes), the banknote processing device 10 reads the identification information ID (x, y) from this storage part 12. Further, the banknote processing device 10 compares the identification information ID read from the storage part 12 and identification information ID memorized in the memory part 14 to each other (S113).

[0108] Specifically, a position in the banknote processing device 10 (hereinafter, "attachment position x") at which the storage part 12x that stores therein banknotes of the denomination A and banknotes of the denomination B is attached is set in advance. Similarly, a position in the banknote processing device 10 (hereinafter, "attachment position y") at which the storage part 12y that stores therein banknotes of the denomination C and banknotes of the denomination D is attached is set in advance. When a storage part 12 is attached to the attachment position x, identification information ID read from this storage part 12 is compared to identification information IDx in the memory part 14. Further, when a storage part 12 is attached to the attachment position y, identification information ID read from this storage part 12 is compared to identification information IDy in the memory part 14.

[0109] After comparing the identification information ID read from the storage part 12 and the identification information ID in the memory part 14 to each other, the banknote processing device 10 determines whether the respective pieces of identification information ID match each other (S114). When it is determined that these pieces of identification information ID match each other (S114: Yes), the banknote processing device 10 ends the attaching time process. On the other hand, when it is determined that these pieces of identification information ID do not match each other (S114: No), the banknote processing device 10 shifts to the attachment error state (S115). In the attachment error state, for example, a fact that an appropriate storage part 12 is not attached is notified.<Modifications>

[0110] The modes described above are modified variously. Specific modified aspects are exemplified as follows. Two or more aspects optionally selected from the following examples may be combined with one another as appropriate. (1) In the modes described above, it is configured that the upper limit number L can be set for each denomination; however, this configuration can be changed as appropriate. For example, it is possible to configure that a common upper limit number L is set for respective denominations instead of a configuration in which the upper limit number L can be set differently for respective denominations. Further, it is possible to configure that the range of settable value as the upper limit number L changes with respect to respective denominations. For example, it is possible to configure that among banknotes of respective denominations stored as the change, the larger the denomination is, the smaller the settable value as the upper limit number L is. (2) It is possible to appropriately set control in an error state in each mode. For example, it is possible to configure that, when an attachment error state occurs, identification information ID of a wrongly attached storage part 12 is memorized in the memory part 14 as history information. Further, it is possible to configure that, in the attachment error state, identification information ID of a wrongly attached storage part 12 is displayed on the display part 19.

[0111] Further, it is possible to configure that, in the attachment error state, the banknote processing device 10 can shift to the operation mode. That is, it is possible to configure that, even in the attachment error state, customer's banknotes can be taken in and the change can be discharged. In the above modifications, in the operation mode in the attachment error state, it is preferable to have a configuration in which a fact that the number of banknotes in the storage parts 12 or the collection part 13 is unknown is notified. Note that it is possible to have a configuration in which, in the attachment error state, taking in and discharging of banknotes become unavailable.

[0112] Further, in the modes described above, the trigger for canceling the attachment error state can be changed as appropriate. For example, it is possible configure that the attachment error state is canceled responding to attachment of an appropriate storage part 12 to the banknote processing device 10 as the trigger. Specifically, the attaching time process (see FIG. 10(b)) is also performed in the attachment error state. It is possible to configure that, when it is determined that identification information ID of a newly attached storage part 12 and identification information ID memorized in the banknote processing device 10 (the memory part 14) match each other, the attachment error state is canceled.

[0113] Further, it is possible to configure that, when a predetermined resetting process is performed in a state where an appropriate storage part 12 is attached to the banknote processing device 10 in the attachment error state, this error state is canceled. This resetting process can be performed when, for example, a predetermined reset switch is operated. Further, it is possible to configure that the resetting process is performed responding to start of power supply as the trigger. In this configuration, when the banknote processing device 10 shifts to the attachment error state, by temporarily turning off the power and then turning the power on, this attachment error state can be canceled. (3) In a first embodiment, when a collecting operation is performed in a state where the storage parts 12 are attached to the banknote processing device 10, banknotes in the storage parts 12 are collected in the collection part 13. As described above, when the start button B17 in the denomination specifying image Gd is operated and when the total collection button B11 (see FIG. 9) is operated, the banknotes in the storage parts 12 are collected in the collection part 13. In the first embodiment, in principle, it is not possible to take out the banknotes stored in the storage parts 12 unless the collecting operation described above is performed. Note that it is possible to configure that banknotes can be taken out from the inside of the storage parts 12 by providing a locking device in the storage parts 12 and unlocking this locking device. (4) In each mode, it is preferable to have a configuration in which a history of detaching the storage parts 12 from the main body part 11 (time, mode), a history of detaching the collection part 13 from the main body part 11, a history of storing banknotes in the storage parts 12 (denomination, time, mode), a history of banknotes being discharged from the storage parts 12 (denomination, time, mode), a history of storing banknotes in the collection part 13, a history of banknotes being discharged from the collection part 13, and a history of banknotes being transported from the storage parts 12 to the collection part 13 (denomination, time, mode) are memorized in the memory part 14 and these histories can be displayed on the display part 19. Further, in the first embodiment, banknotes can be discharged in a case of operating the payment button B3 and a case of operating the start button B17. In this configuration, it is possible to configure that a history is memorized in a manner that whether banknotes have been discharged due to operating the payment button B3 or banknotes have been discharged due to operating the start button B17 can be distinguished. (5) In each mode, the configuration to change the upper limit number L can be changed as appropriate. For example, it is possible to configure that the upper limit number L can be changed in a state where banknotes are stored in the storage parts 12. Note that, in the above modifications, the upper limit number L after being changed as desired by a user may be smaller than the number of banknotes stored in the storage parts 12. In consideration of such circumstances, it is possible to configure that the upper limit number L cannot be changed in a state where banknotes are stored in the storage parts 12. For example, it is conceivable to have a configuration in which the upper limit number L can be changed after all banknotes in the storage parts 12 have been shifted to the collection part 13 due to operating the total collection button B11 described above (see FIG. 9).

[0114] It is possible to configure that the upper limit number L can be changed to a number smaller than the number of banknotes stored in the storage parts 12. That is, it is possible to configure that an upper limit number L smaller than the present value of the storage information n can be set. In the above modifications, it is preferable to have a configuration in which, during a period where the upper limit number L is smaller than the storage information n, a notification of a fact that a larger number of banknotes than the upper limit number L are stored in the storage parts 12 (hereinafter, "over notification") is made. For example, the over notification can be made with a dedicated lamp or can be made on the display part 19.

[0115] Further, it is possible to shift to the operation mode during a period where an over notification is made. In this configuration, during a period where an over notification is made, banknotes that are supposed to be stored in the storage parts 12 are stored in the collection part 13. That is, no addition is made to the storage information n in principle. In this modification, it is preferable to have a configuration in which, when the change is discharged and the storage information n becomes smaller than the upper limit number L, an over notification is stopped. Thereafter, when the storage information n reaches an updated upper limit number L again, banknotes are overflowed in the collection part 13.

[0116] It is possible to configure that, during a period where an over notification is made, it is not possible to shift to the operation mode. In this configuration, when an over notification is made, the banknote processing device 10 is caused to shift to the management mode and banknotes in the storage parts 12 are discharged from the banknote inlet / outlet 101 or transported to the collection part 13. In the management mode, when the number of banknotes in the storage parts 12 is adjusted and the storage information n is reduced to be smaller than an updated upper limit number L, the over notification is stopped and the banknote processing device 10 can shift to the operation mode. (6) In the first embodiment described above, the banknote processing device 10 shifts to an error state when the storage parts 12 (the storage units 104) are detached from the main body part 11 (the main body unit 103) in a mode other than the maintenance mode. In place of this configuration, it is possible to configure that, even if the storage parts 12 are detached from the main body part 11 in a mode other than the maintenance mode, it is regarded as a mere setting error and the banknote processing device 10 does not shift to an error state. Similarly, in place of a configuration in which the banknote processing device 10 shifts to an error state when the collection part 13 (the collection cassette 107) is detached from the main body part 11 in a mode other than the maintenance mode, it is possible to configure that, even if the collection part 13 is detached from the main body part 11 in a mode other than the maintenance mode, it is regarded as a mere setting error and the banknote processing device 10 does not shift to an error state. (7) In the first embodiment, as an example of the paper sheet processing device, a change machine (a banknote processing device) has been exemplified. However, the present invention may be also employed for devices other than change machines. Further, the paper sheet processing device may be a device that handles not only banknotes but also securities, tickets, ballots, envelopes, and other various types of paper sheets.
