[0003] [Patent Document 1] JP 2008-210104 A Summary of the Invention [Problem to be solved by the invention]

[0004] In some stores, in order to prevent theft of banknotes, employees may remove banknotes from a change machine and store them in a safe when the store is closed. In such cases, it becomes necessary to transfer the banknotes themselves removed from the change machine to a collection bag or the like (removal work, cash management work). However, for example, when many change machines are installed in a store, the time required for this work may become excessively long, which is an inconvenience. In order to prevent this inconvenience, a configuration may be adopted in which a storage unit that stores banknotes together is detachably provided on the change machine. With the above configuration, the storage unit is removed from the change machine with the banknotes stored therein and stored in the safe, thereby eliminating the need to transfer the banknotes removed from the change machine to a collection bag.

[0005] However, in a configuration in which the storage unit is detachably attached to the change machine, if a store has multiple change machines, a new problem occurs in that the storage unit removed from one change machine may be attached to another change machine. In consideration of the above circumstances, the present invention aims to prevent the inconvenience of attaching a storage unit removed from one paper processing device to another paper processing device. [Means for solving the problem]

[0006] In order to solve the above problems, the paper processing device of the present invention is a paper processing device capable of receiving paper sheets, and capable of storing the received paper sheets. N The device comprises a storage unit and a main body unit having the storage unit removably attached thereto, and the main body unit comprises a memory unit that stores identification information capable of identifying the storage unit corresponding to the main body unit and storage information capable of specifying the number of sheets of paper stored in the storage unit. Effect of the Invention

[0007] According to the present invention, in a configuration in which a storage unit is detachably provided in a paper processing device, the object is to suppress the inconvenience of transferring collection bags, etc., and the inconvenience of attaching a storage unit removed from one paper processing device to another paper processing device.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] FIG. 1 is an external perspective view of a change machine 1, which is an example of a paper processing device. The change machine 1 is configured to be able to communicate with a POS control device 2 installed in a store. Specifically, items purchased by customers are registered in the POS control device 2. Once all items have been registered, the total price of the items (hereinafter, the "purchase amount") is output from the POS control device 2 to the change machine 1. Once the purchase amount has been input, the change machine 1 accepts the customer's bills and coins. When the total amount accepted from the customer (hereinafter, the "accepted amount") reaches the purchase amount, the change machine 1 transmits a message to that effect to the POS control device 2.

[0010] As shown in Fig. 1, the change machine 1 is configured to include a banknote processing unit 100 and a coin processing unit 200. As shown in Fig. 1, the coin processing unit 200 is provided with a coin insertion slot 201 and a coin discharge slot 202. For example, a customer's coins are inserted into the coin insertion slot 201. Furthermore, the coin discharge slot 202 is capable of discharging coins as change.

[0011] As shown in Fig. 1, the banknote processing unit 100 is provided with a banknote inlet / outlet 101. The banknote inlet / outlet 101 is capable of taking in banknotes from a customer and discharging banknotes as change. The banknote processing unit 100 further includes a housing 102. A storage unit 104, which will be described later, is stored inside the housing 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 unit 104 via a transport path 108 (see FIG. 2(b)) inside the housing 102. The banknote processing unit 100 can also discharge banknotes stored in the storage unit 104 from the banknote inlet / outlet 101 as change. Although described in detail below, the storage unit 104 is configured to be removable from the banknote processing unit 100 (main unit 103) (see FIG. 2(c)).

[0013] As shown in FIG. 1, the change machine 1 is provided with a touch panel P and a mode switch S. On the touch panel P, for example, the number of banknotes stored in the change machine 1 is displayed for each denomination. The mode switch S is operated to switch the mode of the change machine 1. As will be described in detail later, the change machine 1 transitions between an operating mode, a management mode, and a maintenance mode. The operating mode is a mode in which banknotes and coins from customers can be accepted and change can be dispensed. The management mode is a mode in which the banknotes stored in the change machine 1 can be managed. The maintenance mode is a mode in which the storage unit 104 can be removed from the change machine 1.

[0014] The above-mentioned mode change switch S is configured as a cylinder lock having a keyhole into which a key can be inserted. For example, when the key inserted into the mode change switch S is rotated to a first position, the change machine 1 transitions to an operation mode. Similarly, when the key is rotated to a second position, the change machine 1 transitions to a management mode, and when the key is rotated to a third position, the change machine 1 transitions to a maintenance mode. In the above-mentioned configuration, by appropriately managing the key of the mode change switch S, the inconvenience of the mode of the change machine 1 being changed illegally is suppressed. However, the configuration for switching the mode of the change machine 1 is not limited to the above example. For example, the mode of the change machine 1 may be changed when a preset password is entered.

[0015] FIG. 2(a) is a diagram for explaining the inside of the banknote processing unit 100 (housing 102) of the change machine 1. FIG. 2(a) is a cross section of the banknote processing unit 100 taken along line AA in FIG. 1. As shown in FIG. 2(a), the housing 102 is equipped with a main unit 103, storage units 104(x, y) detachably attached to the main unit, and a collection cassette 107. As described above, the storage unit 104 stores banknotes that are discharged as change. The storage unit 104 also includes a storage unit 104x and a storage unit 104y. As will be described in detail later, the storage units 104x and 104y store different denominations (A, B, C, D) of banknotes.

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

[0017] Although details will be described later, in this embodiment, an upper limit is set for the number of banknotes to be stored in the storage unit 104 for each denomination of the banknote. Let us assume that a banknote of a denomination that is originally stored in the storage unit 104 is received, and the number of banknotes of that denomination in the storage unit 104 has reached the upper limit. In such a case, the banknote is stored (overflows) in the collection cassette 1077 rather than in the storage unit 104.

[0018] As shown in Fig. 1, the storage unit 104 and the collection cassette 107 are provided in the main unit 103. As will be described in detail with reference to Fig. 2(c), the storage unit 104 is detachably arranged in the main unit 103. The storage unit 104 is configured to be portable when removed from the main unit 103. Furthermore, the collection cassette 107 is detachably arranged in the main unit 103. The collection cassette 107 is configured to be portable when removed from the main unit 103.

[0019] A removable lid 102a is provided at the top opening of the housing 102. In addition, a locking unit L1 is provided on the main unit 103. The storage unit 104 can be removed from the main unit 103 by opening the lid 102a of the housing 102 and inserting a key into the locking unit L1 to unlock it. In addition, a locking unit L2 is provided on the collection cassette 107. The collection cassette 107 can be removed from the main unit 103 by opening the lid 102a of the housing 102 and inserting a key into the locking unit L2 to unlock it. A banknote inlet / outlet 101 is provided on the main unit 103. Banknotes taken in from the banknote inlet / outlet 101 are stored in the storage unit 104 or the collection cassette 107.

[0020] Fig. 2(b) is a diagram for explaining a transport path of banknotes inside the banknote processing unit 100. Note that the housing 102 is omitted in Fig. 2(b). As shown in Fig. 2(b), the storage unit 104 of this embodiment includes drums 106. Banknotes taken into the banknote inlet / outlet 101 are transported to a drum 106 (storage unit 104) corresponding to the denomination of the banknote, and are wound up (stored) in the drum 106. However, the storage unit 104 is not limited to the above specific example and may be modified as appropriate.

[0021] The banknote processing unit 100 of this embodiment can accept banknotes of various denominations including denominations A, B, C, D, E, and F. As shown in FIG. 2(b), the storage unit 104x of the storage units 104 includes a drum 106a and a drum 106b. The storage unit 104y includes a drum 106c and a drum 106d. Of the banknotes accepted by the banknote processing unit 100, banknotes of denominations (A to D) to be used as change are stored in the drum (a to d) corresponding to the denomination of the banknote.

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

[0023] On the other hand, among the banknotes received by the banknote processing unit 100, banknotes of denominations E and F that are not used as change are stored in the collection cassette 107. However, in this embodiment, an upper limit number is set for each drum 106 (denomination). When the number of banknotes stored in the drum 106 reaches the upper limit number, banknotes of a denomination that would normally be stored in that drum 106 are stored in the collection cassette 107.

[0024] As shown in Fig. 2(b), the main unit 103 is provided with a transport path 108 along which banknotes are transported. The main unit 103 includes an identification unit for identifying the denomination of the banknote taken in from the banknote inlet / outlet 101, and changes the route along which the banknote is transported according to the identified denomination. Note that the technology for identifying the denomination of the banknote and the technology for changing the route along which the banknote is transported may be, for example, the technology described in Japanese Patent No. 6505298.

[0025] Specifically, when the denomination of the banknote taken in through the banknote outlet 101 is identified as denomination A, a path is formed for transporting the banknote from the banknote outlet 101 to the drum 106a of the storage unit 104x. However, if the number of banknotes in the drum 106a has reached the upper limit, when a banknote of denomination A is taken in through the banknote outlet 101, a path is formed for transporting the banknote from the banknote outlet 101 to the collection cassette 107. The same applies when a banknote of denomination B, denomination C or denomination D is taken in.

[0026] Furthermore, when a banknote of denomination E is taken in through the banknote outlet 101, the path is changed to one in which the banknote is transported from the banknote outlet 101 to the collection cassette 107. The same applies when a banknote of denomination F is taken in through the banknote outlet 101. When a banknote of denomination A is discharged from the banknote outlet 101, a path is formed in which the banknote is transported from the drum 106a to the banknote outlet 101. The same applies when a banknote of denomination B, a banknote of denomination C or a banknote of denomination D is discharged. Note that, although in this embodiment, the banknote once stored in the collection cassette 107 is configured not to be discharged from the banknote outlet 101, it may be configured so as to be dischargeable.

[0027] FIG. 2(c) is a diagram for explaining the storage units 104(x,y) and the collection cassette 107 removed from the main unit 103. As shown in FIG. 2(c), of the storage units 104(x,y), the storage unit 104x is provided with a connector 105x, and the storage unit 104y is provided with a connector 105y. The main unit 103 is also provided with connectors 111x and 111y. When the storage unit 104x is attached to the main unit 103, the connector 105x and the connector 111x are connected. When the storage unit 104y is attached to the main unit 103, the connector 105y and the connector 111y are connected.

[0028] Although details will be described later, an individual memory 110(x,y) is provided in the storage unit 104(x,y). The individual memory 110 stores an identification information ID for identifying the storage unit 104 in which the individual memory 110 is provided. The main unit 103 also includes a control unit 109. When the connector 105 of the storage unit 104 and the connector 111 of the main unit 103 are connected, the identification information ID stored in the individual memory 110 of the storage unit 104 becomes readable by the control unit 109 of the main unit 103. The control unit 109 determines whether or not the appropriate storage unit 104 has been attached based on the identification information ID.

[0029] The change machine 1 monitors whether the connector 111 of the main unit 103 is connected to the connector 105 of the storage unit 104, and determines whether the storage unit 104 is attached to the main unit 103. In this embodiment, the time when the collection cassette 107 was attached and the time when it was removed are stored in the change machine 1 (main memory 115) as history information. Also, whether the collection cassette 107 is attached is detected by a sensor, and the time when the collection cassette 107 was attached and the time when it was removed are stored in the change machine 1 as history information.

[0030] 3(a) and 3(b) are specific examples of a method for processing banknotes. As described above, the change machine 1 transitions between an active mode, a management mode, and an operation mode. FIG. 3(a) is a specific example of a method for processing banknotes in the active mode. For example, the change machine 1 transitions to the active mode during the opening hours of a store. In the active mode, as described above, the change machine 1 accepts banknotes from customers and dispenses banknotes as change.

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

[0032] FIG. 3(b) is a diagram for explaining a specific example of a method for processing banknotes in the maintenance mode. In the maintenance mode, as described above, the collection cassette 107 can be removed. Specifically, the control unit 109 of the change machine 1 monitors whether the collection cassette 107 has been removed. If the collection cassette 107 is removed in a mode other than the maintenance mode, the change machine 1 transitions to an error state. The time at which the change machine 1 transitions to the error state is stored in the main memory 115 as history information. Similarly, if the storage unit 104 is removed in a mode other than the maintenance mode, the change machine 1 transitions to an error state, and the time at which the change machine 1 transitions to the error state is stored in the main memory 115 as history information.

[0033] On the other hand, even if the collection cassette 107 is removed in the maintenance mode, the change machine 1 does not enter an error state. When the collection cassette 107 is removed from the main unit 103, the banknotes in the collection cassette 107 become available for collection. For example, a store employee switches the change machine 1 to the maintenance mode after the store closes. In the above case, the banknotes in the collection cassette 107 can be removed and stored in the safe S after the store closes (Sb1 in FIG. 3(b)). The above safe S is provided, for example, in the back yard of the store.

[0034] Note that the banknotes in the collection cassette 107 may be stolen even during the store's business hours. Therefore, it may be preferable to remove the banknotes from the collection cassette 107 and store them in the safe S during the store's business hours. In the above case, a store employee switches the change machine 1 to a maintenance mode during the business hours and collects the banknotes in the collection cassette 107 (collects them midway). As will be described in detail later, the change machine 1 stores the number of banknotes in the collection cassette 107 for each denomination as collection information N (see FIG. 5). Before collecting the banknotes in the collection cassette 107, it is necessary to switch the change machine 1 to a management mode and initialize the collection information N.

[0035] As described above, the storage unit 104 can be carried with the banknotes stored therein. In the above embodiment, the storage unit 104 removed from the main unit 103 can be stored in the safe S as is, without removing (leaving) the banknotes from the storage unit 104. Therefore, compared to a configuration in which all banknotes must be removed from the storage unit 104 when the store is closed, for example, this has the advantage of reducing the workload of store employees. Also, compared to a configuration in which banknotes are left in the change machine 1 when the store is closed, for example, this has the advantage of reducing the risk of theft of banknotes used as change.

[0036] However, in a configuration in which the storage unit 104 is removed from the change machine 1 and stored in the safe S when the store is closed, it is necessary to remove the storage unit 104 from the safe S and attach it to the change machine 1 when the store is opened. Also, a store (for example, a large store) may be provided with multiple change machines 1. In the above cases, the multiple storage units 104 removed from the multiple change machines 1 are stored in the safe S.

[0037] When multiple change machines 1 are installed in a store, the number of banknotes stored in the storage unit 104 usually differs for each change machine 1. The number of banknotes stored in the storage unit 104 is stored as storage information n in the main unit 103 of the change machine 1 (see FIG. 5). In the above configuration, if a storage unit 104 is attached to a change machine 1 other than the one to which it should be attached, a problem may arise in which the storage information n stored in the change machine 1 does not match the number of banknotes actually stored by the storage unit 104. In this embodiment, the above problem is prevented by storing identification information ID in the storage unit 104. The above configuration will be described in detail later.

[0038] Fig. 4 is a hardware configuration diagram of the change machine 1. As shown in Fig. 4, the change machine 1 includes the above-mentioned storage unit 104(x, y) and collection cassette 107. The change machine 1 also includes a connector 111(x, y) and a control unit 109. The above-mentioned connector 111 and control unit 109 are provided on the main unit 103 side of the change machine 1.

[0039] The control unit 109 includes a central processing unit (CPU) 112, a read only memory (ROM) 113, a random access memory (RAM) 114, and a main memory 115. The ROM 113 stores various types of information in a non-volatile manner. For example, the ROM 113 stores various types of information including programs. The CPU 112 executes the programs stored in the ROM 113. The RAM 114 can temporarily store various types of information. For example, the RAM 114 stores various types of information generated when the CPU 112 executes a program.

[0040] For example, the CPU 112 executes a program to realize an operation of taking in a banknote from the banknote inlet / outlet 101. The 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 judges the authenticity and denomination of the banknote based on the detection signal. The control unit 109 generates a drive signal for driving a motor and a solenoid according to the judgment result of the banknote. According to the above configuration, the banknote is transported to and stored in either the storage unit 104 (drums 106a-d) or the collection cassette 107 of the change machine 1. Note that if an appropriate judgment result is not obtained, a reject operation is executed, and the banknote is discharged from the banknote inlet / outlet 101.

[0041] A flash memory, for example, is preferably used as the main memory 115. Although a flash memory has been exemplified as the main memory 304, other storage means may be used as the main memory 304. For example, an EEPROM may be used as the main memory 304. Various information is stored in the main memory 115. For example, the main memory 115 stores storage information n(a-d) indicating the number of bills of each denomination stored in the storage unit 104 (see FIG. 5 described later). The main memory 115 also stores an identification information ID for identifying the storage unit 104. The identification information ID is assigned to each storage unit 104.

[0042] For example, the identification information ID (IDx) differs between storage units 104x that have been removed from different change machines 1. Similarly, the identification information ID (IDy) differs between storage units 104y that have been removed from different change machines 1. Furthermore, even if the change machine 1 is the same, the identification information ID differs between storage units 104x and 104y. The identification information ID is used when determining whether the storage unit 104 attached to the change machine 1 is appropriate.

[0043] 4, the storage unit 104(x,y) includes drums 106(a,b,c,d), connectors 105(x,y) and individual memories 110(x,y). Specifically, the storage unit 104x among the storage units 104 is provided with a drum 106a for storing denomination A and a drum 106b for storing denomination B, as described above. The storage unit 104y among the storage units 104 is provided with a drum 106c for storing denomination C and a drum 106d for storing denomination D, as described above.

[0044] The connector 105 includes a connector 105x provided in the storage unit 104x and a connector 105y provided in the storage unit 104y of the storage unit 104. As described above, when the storage unit 104x is attached to the change machine 1 (main unit 103), the connector 105x of the storage unit 104x connects to the connector 111x of the main unit 103. Similarly, when the storage unit 104y is attached to the change machine 1, the connector 105y of the storage unit 104y connects to the connector 111y of the main unit 103.

[0045] The individual memories 110 include an individual memory 110x provided in the storage unit 104x of the storage units 104 and an individual memory 110y provided in the storage unit 104y. Each of the individual memories 110(x, y) stores information in a non-volatile manner, including identification information ID for identifying the storage unit 104 in which the individual memory 110 is provided. The information in the individual memories 110 described above can be read by the control unit 109 when the connector 105 of the storage unit 104 in which the individual memory 110 is provided is connected to the connector 111 of the main unit 103.

[0046] 5 is a diagram for explaining specific examples of each piece of information stored in the main memory 115 and the individual memory 110(x, y). As shown in Fig. 5, the main memory 115 (main unit 103 side) stores various pieces of information including first unit information Dx, second unit information Dy, and collection information N. Each piece of 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 indicating the number of banknotes (denomination A) stored in the drum 106a, storage information nb indicating the number of banknotes (denomination B) stored in the drum 106b, the upper limit number La of banknotes stored in the drum 106a, and the upper limit number Lb of banknotes stored in the drum 106b. In the specific example of FIG. 5, it is assumed that 19 banknotes of denomination A are stored in the drum 106a and 30 banknotes of 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 indicating the number of banknotes (denomination C) stored in the drum 106c, storage information nd indicating the number of banknotes (denomination D) stored in the drum 106d, the upper limit number Lc of banknotes stored in the drum 106c, and the upper limit number Ld of banknotes stored in the drum 106d. In the specific example of FIG. 5, it is assumed that one banknote of denomination C is stored in the drum 106c and 17 banknotes of denomination D are stored in the drum 106d.

[0049] When a banknote is stored in the drum 106 (a-d) of the change machine 1, the storage information n corresponding to that drum 106 is incremented. For example, when one banknote (denomination A) is stored in the drum 106a, the storage information na among the storage information n is incremented by the value "1". Also, when a banknote is discharged as change from the drum 106 of the change machine 1, the storage information n corresponding to that drum 106 is decremented. For example, when one banknote (denomination A) is discharged from the drum 106a, the storage information na among the storage information n is decremented by the value "1".

[0050] The upper limit number L(a-d) of banknotes stored in each drum 106(a-d) can be changed in the management mode. That is, in this embodiment, the upper limit number of banknotes to be left in the change machine 1 as change the next day can be changed for each denomination. For example, the number of banknotes required as change may differ depending on the size of the store. Also, in order to reduce the risk of theft, it is desirable not to leave more change than necessary in the change machine 1. By appropriately adjusting the upper limit number L of each drum 106, there is an advantage that the necessary change can be left while reducing the risk of theft.

[0051] Of the various pieces of information stored in the main memory 115, the collection information N (a to f) indicates the number of banknotes stored in the collection cassette 107. Specifically, the collection information N includes collection information Na indicating the number of denomination A banknotes stored in the collection cassette 107, collection information Nb indicating the number of denomination B banknotes, collection information Nc indicating the number of denomination C banknotes, collection information Nd indicating the number of denomination D banknotes, collection information Ne indicating the number of denomination E banknotes, and collection information Nf indicating the number of denomination F banknotes.

[0052] For example, when a bill of denomination E that is not to be used as change is received, the bill is stored in the collection cassette 107, and the value "1" is added to the collection information Ne of the collection information N. When a bill of denomination (A to D) to be used as change is received and the storage information n (a to d) of the bill of the denomination has reached the upper limit number L (a to d), the bill is stored in the collection cassette 107. In the above cases, the collection information N (a to d) indicating the number of bills of the denomination (A to D) to be used as change is added. As described above, the bills in the collection cassette 107 are not discharged as change. Therefore, in principle, the collection information N is not subtracted. However, as described later, when the bills in the collection cassette 107 are collected, the collection information N (a to f) is initialized to the value "0".

[0053] 5, the individual memory 110x of the storage unit 104x stores identification information IDx for identifying the storage unit 104x. As described above, when the storage unit 104 (connector 105) is connected to the connector 111x of the main unit 103, the control unit 109 determines whether the identification information ID stored in the individual memory 110 of the storage unit 104 is appropriate.

[0054] Specifically, when a storage unit 104 is connected to the connector 111x, it is automatically determined whether or not the identification information ID stored in the individual memory 110 of the storage unit 104 matches the identification information IDx stored in the main memory 115 of the control unit 109. If a storage unit 104x removed from a device other than the original change machine 1 is attached to the connector 111x, the above-mentioned determination result will be a mismatch. Also, if a storage unit 104y is connected to the connector 111x (not the connector 111y), the above-mentioned determination result will be a mismatch.

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

[0056] Specifically, when a storage unit 104 is connected to the connector 111y, it is automatically determined whether or not the identification information ID stored in the individual memory 110 of the storage unit 104 matches the identification information IDy stored in the main memory 115 of the control unit 109. If a storage unit 104y removed from a device other than the original change machine is attached to the connector 111y, the above-mentioned determination result will be a mismatch. Also, if a storage unit 104x is connected to the connector 111y (not the connector 111x), the above-mentioned determination result will be a mismatch.

[0057] 6 is a functional block diagram of the banknote processing device 10. For example, the above-mentioned CPU 112 executes a program, causing the change machine 1 to function as the banknote processing device 10. As shown in FIG. 6, the banknote processing device 10 includes a main body unit 11, a storage unit 12x, a storage unit 12y, and a collection unit 13.

[0058] The storage units 12(x, y) are capable of storing banknotes received by the banknote processing device 10 and discharging the stored banknotes. The storage units 12 in this embodiment include a storage unit 12x and a storage unit 12y. For example, the above-mentioned storage unit 104x functions as the storage unit 12x, and the storage unit 104y functions as the storage unit 12y. As shown in FIG. 6, each storage unit 12 stores identification information ID for identifying the storage unit 12.

[0059] Of the storage units 12, the storage unit 12x stores banknotes of denomination A and banknotes of denomination B among the banknotes accepted by the banknote processing device 10. The storage unit 12y stores banknotes of denomination C and banknotes of denomination D among the banknotes accepted by the banknote processing device 10. Note that although the banknote processing device 10 of the present embodiment includes two storage units 12, the number of storage units 12 can be changed as appropriate. For example, one storage unit 12 may be provided, or three or more storage units 12 may be provided.

[0060] The collection unit 13 stores the received banknotes during the period when the number of banknotes in the storage unit 12 has reached the upper limit number L. For example, the above-mentioned collection cassette 107 functions as the collection unit 13. Furthermore, when a banknote of denomination E or a banknote of denomination F that is not used as change is received by the banknote processing device 10, the banknote of that denomination is stored in the collection unit 13.

[0061] The main body 11 detachably includes a storage section 12(x, y) and a collection section 13. For example, the above-mentioned main unit 103 functions as the main body 11. As shown in FIG. 6, the main body 11 includes a storage section 14 and a control section 15. For example, the above-mentioned main memory 115 functions as the storage section 14. Also, the above-mentioned CPU 112 functions as the control section 15.

[0062] The memory unit 14 of the main body unit 11 stores identification information ID capable of identifying the storage unit 12 corresponding to the main body unit 11, and storage information n (a-d) capable of specifying the number of banknotes stored in the storage unit 12. The memory unit 14 also stores collection information N indicating the number of banknotes stored in the collection unit 13 for each denomination (A-D), and each upper limit number L (a-d) of banknotes of each denomination (A-D) to be stored in the storage unit 12. In this embodiment, each piece of information in the memory unit 14 is retained even if the power supply to the banknote processing device 10 is cut off during the period from when the store closes to when it opens.

[0063] The control unit 15 of the main body unit 11 includes a change unit 16, an initialization unit 17, and a transition unit 18. The change unit 16 is capable of changing the upper limit number L stored in the memory unit 14. Specifically, the change unit 16 is capable of changing the upper limit number L for each denomination. In this embodiment, the upper limit number L is set to any value in the range "0 to 100." The numerical range that can be set as the upper limit number L can be appropriately changed depending on, for example, the storage capacity of the storage unit 12 (drum).

[0064] The transition unit 18 transitions to a predetermined management mode. Specifically, when the above-mentioned mode changeover switch S is appropriately operated, the transition unit 18 transitions to any one of the management mode, the operation mode, and the maintenance mode. The initialization unit 17 can initialize the collection information N(a to f) indicating the number of banknotes stored in the collection unit 13 in the management mode.

[0065] Assume a configuration in which both the storage information n and the collection information N are uniformly initialized (hereinafter, "comparative example"). Also assume a case in which, of the banknotes in the storage unit 12 and the collection unit 13, the banknotes in the storage unit 12 are left behind and the banknotes in the collection unit 13 are collected at the time of closing. In the above case, in the above comparative example, the storage information n is initialized even though the banknotes are left behind in the storage unit 12. Therefore, in the above comparative example, a problem occurs in which the number of banknotes actually stored by the storage unit 12 does not match the number of banknotes indicated by the storage information n. According to the initialization unit 17 of this embodiment, the storage information n can be maintained while the collection information N is initialized, thereby suppressing the above problem.

[0066] As shown in FIG. 6, the banknote processing device 10 includes a display unit 19. For example, the above-mentioned touch panel P functions as the display unit 19. The display unit 19 displays various information. For example, the display unit 19 displays the current value of storage information n (see G0 in FIG. 8 described later). The display unit 19 also displays the current value of collection information N (see Gc in FIG. 8 described later). The above-mentioned display unit 19 is configured to be able to receive touch operations. Images displayed by the display unit 19 will be described later with reference to FIG. 8.

[0067] FIG. 7 is a diagram for explaining a specific example of leaving banknotes in the storage unit 12x. As described above, banknotes of denomination A and banknotes of denomination B are stored in the storage unit 12x. In the specific example of FIG. 7, a case where banknotes of denomination A and banknotes of denomination B are left in the storage unit 12x will be explained. Also, it is assumed that the storage unit 12x is removed from the banknote processing device 10 and stored in the safe S when the store is closed. Note that the storage unit 12y is omitted in FIG. 7. The banknotes in the storage unit 12y can be processed in the same way as the banknotes in the storage unit 12x.

[0068] Specifically, in FIG. 7, it is assumed that the storage units 12x are removed from the plurality of banknote processing devices 10 at the time of closing, and the plurality of storage units 12x are stored in the safe S. Hereinafter, for the sake of explanation, one of the plurality of banknote processing devices 10 is referred to as a "banknote processing device 10v" and the other is referred to as a "banknote processing device 10w". In addition, the storage unit 12x of the banknote processing device 10v is referred to as a "storage unit 12xv", and the storage unit 12x of the banknote processing device 10w is referred to as a "storage unit 12xw". Similarly, the memory unit 14 of the banknote processing device 10v is referred to as a "storage unit 14v", and the memory unit 14 of the banknote processing device 10w is referred to as a "storage unit 14w". In addition, FIG. 7 shows a part of each piece of information (na, nb, IDx) stored in the memory unit 14v (main body side) of each banknote processing device 10v. Similarly, part of each piece of information (na, nb, IDx) stored in the memory unit 14w of each banknote processing device 10w is shown.

[0069] FIG. 7 shows the number of banknotes of denomination A and the number of banknotes of denomination B stored in the storage unit 12x(v, w). In the specific example of FIG. 7, it is assumed that n1 banknotes of denomination A and n2 banknotes of denomination B are stored in the storage unit 12xv. That is, it is assumed that n1 banknotes of denomination A and n2 banknotes of denomination B are stored in the banknote processing device 10v at the time of closing. In the above case, the storage information na (the number of banknotes of denomination A) stored in the memory unit 14v of the banknote processing device 10v is "n1" (na=n1). Similarly, the storage information nb (the number of banknotes of denomination B) stored in the memory unit 14v of the banknote processing device 10v is "n2" (nb=n2).

[0070] In the specific example of FIG. 7, it is assumed that m1 (where m1 ≠ n1) denomination A banknotes are stored in the storage unit 12xw. That is, it is assumed that m1 denomination A banknotes are stored in the banknote processing device 10w at the time of closing. In the above case, the storage information na (the number of denomination A banknotes) stored in the memory unit 14w of the banknote processing device 10w is "m1" (na = m1). It is also assumed that m2 denomination B banknotes are stored in the banknote processing device 10w at the time of closing. In the above case, the storage information nb (the number of denomination B banknotes) stored in the memory unit 14w of the banknote processing device 10w is "m2" (nb = m2).

[0071] When the store is opened, an employee of the store removes each storage unit 12 from the safe S and attaches it to each banknote processing device 10. However, the banknotes stored in the storage units 12 are left there when the store is closed. Also, storage information n indicating the number of banknotes stored in the storage units 12 when the store is closed is stored in the memory unit 14 (on the main body unit 11 side). Therefore, in order to match the number of banknotes actually stored in the storage units 12 with the number of banknotes indicated by the storage information n in the memory unit 14, the storage units 12 removed from the banknote processing device 10 when the store is closed must be attached to the same banknote processing device 10 when the store is opened. For example, in the specific example of FIG. 7, the storage unit 12xv removed from the banknote processing device 10v when the store is closed must be attached to the banknote processing device 10v, not to the banknote processing device 10w.

[0072] Incidentally, for example, the more banknote processing devices 10 installed in a store, the more storage units 12 will be stored in the safe S when the store is closed. When there are many storage units 12 stored in the safe S, there is a circumstance that a banknote processing device 10 removed when the store is closed is easily attached to another banknote processing device 10 when the store is opened. Taking the above circumstances into consideration, the present embodiment employs a configuration for suppressing the above inconvenience.

[0073] Specifically, the storage unit 12 in this embodiment stores an identification information ID unique to the storage unit 12. Also, the memory unit 14 (on the main body unit 11 side) of the banknote processing device 10 stores the identification information ID of the storage unit 12 to be attached to the banknote processing device 10. For example, in the specific example of FIG. 7, the identification information IDxv is stored in the storage unit 12xv removed from the banknote processing device 10v. Also, the identification information IDxv is stored in the memory unit 14v of the banknote processing device 10v. Similarly, the identification information IDxw is stored in the storage unit 12xw removed from the banknote processing device 10w (IDxv ≠ IDxw). Also, the identification information IDxw is stored in the memory unit 14w of the banknote processing device 10w.

[0074] When the storage unit 12 is attached, the banknote processing device 10 of this embodiment automatically reads out the identification information ID from the storage unit 12. The banknote processing device 10 also determines whether or not the identification information ID stored in the memory unit 14 matches the identification information ID of the storage unit 12. If the identification information ID of the storage unit 12 matches the identification information ID of the memory unit 14 (on the main body unit 11 side) (for example, Sc1 in Fig. 7), the banknote processing device 10 does not transition to an attachment error state.

[0075] On the other hand, if the identification information ID of the storage unit 12 does not match the identification information ID of the memory unit 14 (on the main body unit 11 side) (for example, Sc2 in Fig. 7), the banknote processing device 10 transitions to an attachment error state. In the attachment error state, for example, a notification is given that an inappropriate storage unit 12 has been attached. Specifically, a message to the effect that an inappropriate storage unit 12 has been attached is displayed on the display unit 19. With the above configuration, it is possible to prevent the inconvenience of attaching the storage unit 12 removed from one banknote processing device 10 at closing time to another banknote processing device 10 at opening time.

[0076] Fig. 8 is a diagram for explaining each image (Go, Gm, Gc, Gh) displayed on the display unit 19. As described above, the banknote processing device 10 transitions between the operation mode, the management mode, and the maintenance mode. Fig. 8 shows a schematic diagram of an operation mode image Go displayed in the operation mode, a management mode image Gm, a collection information image Gc, and a replenishment image Gh displayed in the management mode.

[0077] As shown in Fig. 8, the operation mode image Gо displays the number of banknotes stored in the storage unit 12 of the banknote processing device 10 for each denomination. In other words, the operation mode image Gо displays the remaining number of banknotes that can be dispensed as change for each denomination. In the specific example of Fig. 8, it is assumed that 19 banknotes of denomination A, 30 banknotes of denomination B, 1 banknote of denomination C, and 17 banknotes of denomination D are stored in the storage unit 12.

[0078] In this embodiment, the operation mode image Gо issues a notification according to the remaining number of banknotes stored in the storage unit 12. For example, when the remaining number of banknotes in the storage unit 12 is low, a notification to that effect is issued. As described above, the banknote processing device 10 stores storage information n (a to d) indicating the remaining number of banknotes of each denomination (A to D) in the storage unit 12. When the storage information n is in the range "0 to 5", the banknote processing device 10 displays the remaining number of banknotes of the denomination corresponding to the storage information n in a special manner (orange).

[0079] In the specific example of FIG. 8, it is assumed that the remaining number of banknotes of denomination C is 5 or less (1 banknote). In other words, it is assumed that the storage information nc is the numerical value "5" or less. In the above case, the remaining number of banknotes of denomination C is displayed in orange in the operation mode image Gо. As will be described in detail later, when the remaining number of banknotes in the storage unit 12 is low, banknotes are replenished to the storage unit 12 by a replenishment operation. In this embodiment, since it is notified that the remaining number of banknotes in the storage unit 12 is low, it becomes easier to prevent a situation in which there is a shortage of banknotes that can be dispensed as change.

[0080] Furthermore, the maximum number of banknotes that can be stored in the storage unit 12 is predetermined for each denomination (for each drum 106), and when the number of banknotes stored in the storage unit 12 approaches the maximum number, a near-full notification is issued in the operation mode image Gо. Specifically, when storage information n indicating the number of banknotes stored in the storage unit 12 approaches the maximum number (for example, when "maximum number-n≦5"), the number of banknotes of the denomination corresponding to the storage information n is displayed in a special manner in the operation mode image Gо. However, when an arbitrary upper limit number L is set, the above near-full notification is not issued.

[0081] As shown in FIG. 8, when the mode change switch S is operated in the operation mode, a management mode image Gm is displayed in place of the operation mode image Gо. The management mode image Gm displays the number of banknotes stored in the storage unit 12, similar to the operation mode image Gо. The management mode image Gm also displays a refill button B1, a recovery button B2, a payment button B3, and a cassette display button B4. For example, the payment button B3 is operated when paying banknotes to a customer. Specifically, when the payment button B3 is operated by touch, the number of banknotes to be discharged from the storage unit 12 can be set for each denomination. The set number of banknotes is also discharged from the banknote processing device 10 (banknote inlet / outlet 101), and the storage information n is subtracted according to the number of discharged banknotes.

[0082] When the cassette display button B4 on the management mode screen Gm is touched, a collection information image Gc is displayed. The collection information image Gc displays the number of banknotes stored in the collection unit 13 for each denomination. Specifically, the banknote processing device 10 displays the number of banknotes of each denomination (A to F) stored in the collection unit 13 based on the collection information N (a to f) stored in the memory unit 14. The collection information image Gc also displays the total amount of money stored in the collection unit 13. The total amount of money stored in the collection unit 13 is calculated based on the collection information N.

[0083] In the specific example of FIG. 8, it is assumed that three banknotes of denomination A, 23 banknotes of denomination E, and 30 banknotes of denomination F are stored in the collection unit 13, and banknotes of other denominations (B to D) are not stored. As described above, banknotes of denominations (A to D) used as change are stored in the storage unit 12 in principle. However, when the upper limit number L of banknotes of denominations (A to D) used as change is stored in the storage unit 12 and a new banknote of that denomination is received, that banknote is stored (overflows) in the collection unit 13. In the specific example of FIG. 8, it is assumed that three banknotes of denomination A overflow.

[0084] The collection information image Gc described above is displayed at an appropriate time. For example, when the store is opened or closed, the collection information image Gc is displayed to confirm the number of banknotes stored in the collection unit 13. If there are banknotes remaining in the collection unit 13 when the store is opened or closed, the store employee collects the banknotes from the collection unit 13 and stores them in the safe. Also, during the business period of the store, the collection information image Gc is displayed to confirm the number of banknotes stored in the collection unit 13. If a large amount of banknotes are stored in the collection unit 13 during the business period of the store, the store employee collects the banknotes from the collection unit 13 and stores them in the safe (collects them midway).

[0085] Although details will be described later, when collecting banknotes in the collection unit 13, it is necessary to initialize the collection information N. Specifically, as shown in FIG. 8, when the collection button B2 of the management mode image Gm is touched, a selection image Gs is displayed. A collection image Ga is displayed via the selection image Gs (see FIG. 9 described later). When the collection image Ga is appropriately touched, the collection information N is initialized. When the end button B5 of the collection information image Gc is touched, the management mode image Gm is displayed in place of the collection information image Gc.

[0086] As shown in FIG. 8, when the refill button B1 on the management mode image Gm is touched, a refill image Gh is displayed. During the period when the refill image Gh is displayed, banknotes to be used as change can be refilled into the storage unit 12. For example, when the number of banknotes in the storage unit 12 is low at the time of opening, banknotes are refilled via the refill screen Gh. Also, as described above, the operation mode image Gо may notify which of each denomination of banknotes in the storage unit 12 has a low remaining number. In the above cases, banknotes are refilled into the storage unit 12 during the business hours of the store.

[0087] An end button B5, a start button B6 and a stop button B7 are displayed on the refill image Gh. When the start button B6 is touched, the taking in of banknotes starts from the banknote outlet 101. Specifically, the banknote outlet 101 is formed so that the leading end of a banknote bundle can be inserted. When the start button B6 is touched with the leading end of the banknote bundle inserted into the banknote outlet 101, the banknotes of the banknote bundle are taken in one by one into the banknote processing device 10. When the stop button B7 is touched during the period in which the above-mentioned taking in operation is being performed, the taking in operation stops.

[0088] As shown in FIG. 8, the refill image Gh displays the number of refilled banknotes for each denomination. In the specific example of FIG. 8, it is assumed that 10 banknotes of denomination C have been refilled. The refill image Gh also displays the total amount refilled. When the end button B5 of the refill image Gh is touched, the management mode image Gm is displayed in place of the refill image Gh. As described above, an upper limit number L is set for each denomination for the number of banknotes to be stored in the storage unit 12. If a banknote is taken in by touching the refill image Gh (B6) and the storage information n for the denomination of the banknote has reached the upper limit number L, the banknote is discharged from the banknote inlet / outlet 101.

[0089] Fig. 9 is a diagram for explaining each image displayed when a banknote is collected from the banknote processing device 10. Fig. 9 shows a schematic diagram of a selection image Gs, a schematic diagram of a collected image Ga, and a schematic diagram of a denomination designation image Gd.

[0090] The selection image Gs in Fig. 9 is displayed when the collection button B2 of the management mode image Gm is touched, as explained using Fig. 8. The selection image Gs is an image for enabling selection of banknotes to be collected from the banknote processing device 10 (storage unit 12, collection unit 13). Specifically, the selection image Gs displays an end button B5, a cassette collection button B8, a denomination designation button B9, a number designation button B10, and a full collection button B11. For example, the cassette collection button B8 is touched when collecting banknotes currently stored in the collection unit 13.

[0091] The collection image Ga in FIG. 9 is displayed when the cassette collection button B8 of the selection image Gs is touched. The collection image Ga displays an end button B5 and an initialization button B12. When the initialization button B12 is touched, the collection information N is initialized. Specifically, the collection information N includes collection information Na indicating the number of banknotes of denomination A stored in the collection unit 13, collection information Nb indicating the number of banknotes of denomination B, collection information Nc indicating the number of banknotes of denomination C, collection information Nd indicating the number of banknotes of denomination D, collection information Ne indicating the number of banknotes of denomination E, and collection information Nf indicating the number of banknotes of denomination F. When the initialization button B12 is touched, the collection information N (a to f) is initialized to the numerical value "0".

[0092] When the collection information N is initialized, it is necessary to remove the banknotes from the collection unit 13 before transitioning to the operation mode. If the banknotes are not removed from the collection unit 13 after initializing the collection information N, the number of banknotes indicated by the collection information N will not match the number of banknotes actually stored in the collection unit 13. For example, after initializing the collection information N, a store employee transitions to the maintenance mode, removes the collection unit 13, and removes the banknotes.

[0093] As shown in Fig. 9, when the denomination designation button B9 is touched, a denomination designation image Gd is displayed. The denomination designation button B9 of the selection image Gs is touched when collecting some (or all) of the banknotes in the storage unit 12 in addition to the banknotes currently stored in the collection unit 13. As shown in Fig. 9, the denomination designation image Gd displays a denomination button B13 corresponding to denomination A, a denomination button B14 corresponding to denomination B, a denomination button B15 corresponding to denomination C, a denomination button B16 corresponding to denomination D, and a start button B17. When a denomination button B (13 to 16) is touched, the denomination corresponding to the denomination button B is selected.

[0094] When the start button B17 is touched after selecting a denomination with the denomination buttons B (13 to 16), banknotes of the selected denomination are transported from the storage unit 12 to the collection unit 13. The banknote processing device 10 also initializes storage information n (a to d) indicating the number of banknotes transported from the storage unit 12 to the collection unit 13 to the numerical value "0". Also, the collection information N is updated according to the banknotes stored in the collection unit 13. After transporting the banknotes in the storage unit 12 to the collection unit 13 with the denomination designation button B9 (start button 17), the store employee initializes the storage information N with the above-mentioned collection image Ga, and then collects the banknotes in the collection unit 13. In this embodiment, when the start button B17 is touched after selecting multiple denomination buttons B, banknotes of multiple denominations can be collected at once to the collection unit 13.

[0095] The number designation button B10 is operated when a designated number of banknotes is to be collected from the storage unit 12. Specifically, when the number designation button B10 is operated, a number designation image is displayed, which allows the number to be designated for each denomination. The number designation image is a screen on which the number of banknotes to be collected can be input for each denomination. When the number of banknotes is designated by the number designation image, the designated number of banknotes is discharged from the banknote outlet 101. In addition, the storage information n in the memory unit 14 is updated according to the discharged banknotes. According to the number designation image described above, the banknotes in the storage unit 12 can be collected without removing the collection unit 13. However, the number of banknotes designated by the number designation image may be transported to the collection unit 13.

[0096] The all collection button B11 is operated when all banknotes are to be collected from the banknote processing device 10. Specifically, when the all collection button B11 is operated, all banknotes stored in the storage unit 12 are transported to the collection unit 13. After all banknotes have been transported to the collection unit 13, the store employee initializes the storage information N using the above-mentioned collection image Ga, and then collects the banknotes in the collection unit 13.

[0097] Fig. 10(a) is a flowchart of a banknote storage process of the banknote processing device 10. The banknote processing device 10 executes the banknote storage process when storing banknotes in the storage unit 12 or the collection unit 13. Specifically, the banknote storage process is executed when a banknote is inserted into the banknote inlet / outlet 101. Note that, as a technique for transporting banknotes from the banknote inlet / outlet 101 to the storage unit 12 or the collection unit 13, for example, the technique described in Japanese Patent No. 6505298 can be adopted.

[0098] When a banknote is taken in through the banknote inlet / outlet 101, the banknote processing device 10 identifies the denomination of the banknote (S100). Specifically, the banknote processing device 10 identifies the denomination of the banknote based on a detection signal from a sensor provided in the above-mentioned transport path 108 (see FIG. 2(b)). After that, the banknote processing device 10 judges whether the denomination of the taken in banknote is any of denominations A to D (S101). In other words, the banknote processing device 10 judges whether the taken in banknote is a banknote to be used as change.

[0099] When it is determined that the banknote is not a banknote to be used as change (it is a banknote of denomination E or denomination F) (S101: No), the banknote processing device 10 transports the banknote to the collection unit 13 and stores it (S102). Furthermore, the banknote processing device 10 updates (adds) the collection information N according to the denomination of the banknote stored in the collection unit 13 (S103). For example, when a banknote of denomination E is stored in the collection unit 13, a value "1" is added to the collection information Ne of the collection information N. In this embodiment, the collection information N is updated after the operation of storing the banknote in the collection unit 13 is completed. Therefore, if the banknote is jammed on the way of the transport path 108 to the collection unit 13, the collection information N is not updated. In the above cases, after the banknote is removed from the transport path 108, the banknote is inserted again into the banknote inlet / outlet 101.

[0100] On the other hand, when a banknote of a denomination (A to D) to be used as change is taken in (S101; Yes), the banknote processing device 10 judges whether or not the storage information n (a to d) corresponding to the denomination is equal to or larger than the upper limit number L (a to d) (S104). In other words, it judges whether or not the newly taken in banknote of the denomination has already been stored up to the upper limit number L in the storage unit 12. For example, when a banknote of denomination A is taken in, the banknote processing device 10 judges whether or not the storage information na indicating the number of banknotes of denomination A stored in the storage unit 12 has reached the upper limit number La.

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

[0102] When the storage information n corresponding to the denomination of the taken banknote has reached the upper limit number L (S104: Yes), the banknote processing device 10 stores the banknote in the collection unit 13. In addition, the collection information N is updated according to the denomination of the banknote. After updating the collection information N, the banknote processing device 10 ends the banknote storage process. For example, when a banknote of denomination A is stored in the collection unit 13 (when a banknote of denomination A has overflowed), the collection information Na is incremented by a value "1".

[0103] Fig. 10(b) is a flowchart of the attachment process executed by the banknote processing device 10. The attachment process is executed to determine whether or not an appropriate storage unit 12 has been attached to the banknote processing device 10 (main body unit 11). As shown in Fig. 10(b), when the attachment process starts, the banknote processing device 10 determines whether or not it is immediately after the power has been turned on (S110). Specifically, the banknote processing device 10 executes the attachment process at a predetermined cycle while the power is being supplied. In step S110, it is determined whether or not this is the first attachment process since the power has been turned on.

[0104] If it is determined that the power has just been turned on (S110: Yes), the banknote processing device 10 executes the processes from step S112 onwards to determine whether or not an appropriate storage unit 12 has been attached. The above configuration has the advantage that even if a storage unit 12 is attached to the banknote processing device 10 during a period when the power is cut off, the suitability of the storage unit 12 can be determined.

[0105] When it is determined that the power has not been turned on immediately (S110: No), the banknote processing device 10 judges whether or not a new storage unit 12 has been attached to the main body 11 (S111). Specifically, when a storage unit 12 is attached to the main body 11 of the banknote processing device 10, a connector (110) of the storage unit 12 connects to a connector (111) of the main body 11. The banknote processing device 10 monitors whether or not each connector is connected. When each connector changes from a disconnected state to a connected state, it is determined that a new storage unit 12 has been attached.

[0106] When it is determined that the storage unit 12 is not newly attached (S111: No), the banknote processing device 10 ends the attachment process. When it is determined as "No" in the above step S111, it is assumed that the storage unit 12 is in a state where it has been removed from the main body unit 11, or the state where the storage unit 12 is still attached to the main body unit 11.

[0107] On the other hand, if it is determined that the storage unit 12 has been newly attached (S111: Yes), the banknote processing device 10 reads out the identification information ID(x, y) from the storage unit 12. In addition, the banknote processing device 10 compares the identification information ID read out from the storage unit 12 with the identification information ID stored in the memory unit 14 (S113).

[0108] Specifically, the position in the banknote processing device 10 where the storage unit 12x for storing denomination A banknotes and denomination B banknotes is attached (hereinafter, "attachment position x") is determined in advance. Similarly, the position in the banknote processing device 10 where the storage unit 12y for storing denomination C banknotes and denomination D banknotes is attached (hereinafter, "attachment position y") is determined in advance. When the storage unit 12 is attached to the attachment position x, the identification information ID read from the storage unit 12 is compared with the identification information IDx in the memory unit 14. Also, when the storage unit 12 is attached to the attachment position y, the identification information ID read from the storage unit 12 is compared with the identification information IDy in the memory unit 14.

[0109] After comparing the identification information ID read from the storage unit 12 with the identification information ID in the memory unit 14, the banknote processing device 10 judges whether or not the identification information IDs match (S114). If it is judged that the identification information IDs match (S114: Yes), the banknote processing device 10 ends the attachment process. On the other hand, if it is judged that the identification information IDs do not match (S114: No), the banknote processing device 10 transitions to an attachment error state (S115). In the attachment error state, for example, a message is displayed to the effect that an appropriate storage unit 12 is not attached.

[0110] <Modification> The above embodiments can be modified in various ways. Specific modified embodiments are exemplified below. Two or more embodiments selected from the following examples can be appropriately combined.

[0111] (1) In each of the above embodiments, the upper limit number L can be set for each denomination, but the above configuration can be modified as appropriate. For example, instead of a configuration in which the upper limit number L can be made different for each denomination, a configuration in which a common upper limit number L is set for each denomination may be used. Also, a configuration in which the range of values ​​that can be set as the upper limit number L varies for each denomination may be used. For example, a configuration in which the value that can be set as the upper limit number L for each denomination of banknotes stored as change is smaller may be used.

[0112] (2) The control in each type of error state can be set appropriately. For example, when an installation error state occurs, the identification information ID of the incorrectly installed storage unit 12 may be stored as history information in the memory unit 14. Also, in the installation error state, the identification information ID of the incorrectly installed storage unit 12 may be displayed on the display unit 19.

[0113] Also, the configuration may be such that the operation mode can be switched to in the attachment error state. That is, the configuration may be such that the customer's banknotes can be taken in and the change can be discharged even in the attachment error state. In the above modified example, it is preferable that the operation mode in the attachment error state notifies the user that the number of banknotes in the storage unit 12 and the recovery unit 13 is unknown. However, the configuration may be such that the taking in and discharging of banknotes is impossible in the attachment error state.

[0114] In each of the above embodiments, the trigger for releasing the attachment error state can be changed as appropriate. For example, the attachment error state may be released when an appropriate storage unit 12 is attached to the banknote processing device 10. Specifically, the above-mentioned attachment process (see FIG. 10(b)) is also executed in the attachment error state. The attachment error state may be released when it is determined that the identification information ID of the newly attached storage unit 12 matches the identification information ID stored in the banknote processing device 10 (storage unit 14).

[0115] Also, when a predetermined reset process is executed in a state where an appropriate storage unit 12 is attached to the banknote processing device 10 in the attachment error state, the error state may be released. The above reset process may be executed, for example, when a predetermined reset switch is operated. Also, the reset process may be executed when the supply of power is started. In the above configuration, when the banknote processing device 10 transitions to the attachment error state, the attachment error state can be released by turning the power OFF once and then turning the power ON again.

[0116] (3) In the first embodiment, when a collection operation is executed with the storage unit 12 attached to the banknote processing device 10, the banknotes in the storage unit 12 are collected into the collection unit 13. As described above, when the start button B17 of the denomination designation image Gd is operated, and when the all collection button B11 (see FIG. 9) is operated, the banknotes in the storage unit 12 are collected into the collection unit 13. In the first embodiment, in principle, the banknotes stored in the storage unit 12 cannot be removed by any means other than the above-mentioned collection operation. However, a locking device may be provided in the storage unit 12, and when the locking device is unlocked, the banknotes may be removed from inside the storage unit 12.

[0117] (4) In each embodiment, a configuration is preferable in which the history (time, mode) of the storage unit 12 being removed from the main body unit 11, the history of the collection unit 13 being removed, the history of banknotes being stored in the storage unit 12 (denomination, time, mode), the history of banknotes being discharged from the storage unit 12 (denomination, time, mode), the history of banknotes being stored in the collection unit 13, the history of banknotes being discharged from the collection unit 13, and the history of banknotes being transported from the storage unit 12 to the collection unit 13 (denomination, time, mode) are recorded in the memory unit 14 and can be displayed on the display unit 19. In the first embodiment, banknotes can be discharged when the payment button B3 is operated and when the start button B17 is operated. In the above configuration, a configuration may be used in which the history is stored so as to distinguish whether the banknotes are discharged by operating the payment button B3 or the start button B17.

[0118] (5) In each embodiment, the configuration for changing the upper limit number L may be modified as appropriate. For example, the configuration may be such that the upper limit number L is changeable while banknotes are stored in the storage unit 12. However, in the above modified examples, the upper limit number L after the change desired by the user may be less than the number of banknotes stored in the storage unit 12. Taking the above circumstances into consideration, the configuration may be such that the upper limit number L cannot be changed while banknotes are stored in the storage unit 12. For example, a configuration may be considered in which the upper limit number L is changeable after all banknotes in the storage unit 12 are transferred to the collection unit 13 by the above-mentioned full collection button B11 (see FIG. 9).

[0119] The upper limit number L may be changed to a number smaller than the number of banknotes stored in the storage unit 12. That is, the upper limit number L may be set to a number smaller than the current value of the storage information n. In the above modified example, a preferable configuration is one in which, during a period when the upper limit number L is smaller than the storage information n, a notification is issued to the effect that more banknotes than the upper limit number L are stored in the storage unit 12 (hereinafter, "over notification"). For example, the over notification may be issued by a dedicated lamp or by the display unit 19.

[0120] Also, it may be possible to switch to the operating mode during the period when the over notification is executed. In the above configuration, during the period when the over notification is executed, the banknotes that are originally stored in the storage unit 12 are stored in the collection unit 13. That is, the storage information n is not incremented as a rule. In this modified example, it is preferable that the over notification is stopped when the change is discharged and the storage information n falls below the upper limit number L. Thereafter, when the storage information n reaches the updated upper limit number L again, the banknotes overflow into the collection unit 13.

[0121] It is also possible to configure the system so that it is not possible to switch to the operating mode during the period when the over-alert is being executed. In the above configuration, when the over-alert is executed, the system switches to the management mode and the banknotes in the storage unit 12 are discharged from the banknote inlet / outlet 101 or transported to the storage unit 12. When the number of banknotes in the storage unit 12 is adjusted in the management mode and the storage information n falls below the updated upper limit number L, the over-alert is stopped and the system can switch to the operating mode.

[0122] (6) In the first embodiment described above, when the storage section 12 (storage unit 104) is removed from the main body section 11 (main unit 103) in a mode other than the maintenance mode, the state transitions to an error state. Instead of the above configuration, even if the storage section 12 is removed from the main body section 11 in a mode other than the maintenance mode, the state may be configured not to transition to an error state as a simple setting error. Similarly, instead of the configuration in which the error state transitions when the collection section 13 (collection cassette 107) is removed from the main body section 11 in a mode other than the maintenance mode, the state may be configured not to transition to an error state as a simple setting error.

[0123] (7) In the first embodiment, a change dispenser (banknote processing device) is illustrated as an example of a paper processing device. However, the present invention may be applied to devices other than change dispensers. In addition, the paper processing device is not limited to banknotes, and may be a device that handles securities, tickets, ballots, envelopes, and various other types of paper.
