Currency management system, currency processing device, currency management device, and currency management method
[0001] The present disclosure relates to a currency management system, a currency processing device, a currency management device, and a currency management method for managing currency information.
[0002] Conventionally, various currency processing devices have been used. For example, Patent Document 1 discloses a device that reads a serial number from each banknote. The serial number is identification information unique to each banknote. If there are two banknotes with the same serial number, it means that at least one of them is a counterfeit banknote. The device described in Patent Document 1 reads the serial number of each banknote when sorting the banknotes and stores it in a list. When a banknote with the same serial number as the one in the list is found, that is, when two banknotes with the same serial number are found, the device displays a warning screen prompting the user for confirmation.
[0003] Japanese Unexamined Patent Application Publication No. 2016-43023
[0004] In addition to using the serial number to detect counterfeit banknotes as in the above prior art, for example, the serial number may also be used to confirm whether a banknote processed earlier and a banknote processed later by the same or another currency processing device are the same banknote. However, the use of the serial number in currency processing devices has been limited. For example, conventional currency processing devices could not use the information of banknotes rejected due to reasons such as identification abnormalities or conveyance abnormalities in association with the serial number.
[0005] The present disclosure has been made in view of the problems in the above prior art, and one of its purposes is to provide a currency management system, a currency processing device, a currency management device, and a currency management method that can use information related to rejected banknotes in association with the serial number.
[0006] The currency management system according to the present disclosure includes a currency processing device that transmits the serial number of a rejected banknote that has undergone banknote processing and been rejected, and banknote information including information obtained at the time of identifying the rejected banknote, and a management device that manages the banknote information of the rejected banknote received from the currency processing device in association with the serial number.
[0007] In the above configuration, the management device may determine how to handle the rejected banknotes based on the information received from the currency processing device, and transmit instruction information including the serial number of the rejected banknotes and the handling method to the currency processing device, and the currency processing device may process the banknotes having the serial number included in the instruction information based on the handling method included in the instruction information.
[0008] In the above configuration, the management device may transmit the instruction information to a currency processing device other than the banknote information transmission device, and the other currency processing device may process banknotes having the serial numbers included in the instruction information based on the handling method included in the instruction information.
[0009] In the above configuration, the management device may determine how to handle banknotes having the same attributes as the rejected banknotes based on the information received from the currency processing device, and transmit instruction information including the attributes and the handling method to a plurality of currency processing devices, including the currency processing device. Each currency processing device may then process banknotes having the attributes included in the instruction information based on the handling method included in the instruction information. For example, the denomination may be specified as an attribute to change the handling method for banknotes of the same denomination as the rejected banknotes.
[0010] In the above configuration, the attribute may be at least one of the following: a range of serial numbers including the serial number of the rejected banknote, the denomination of the rejected banknote, or version information of the rejected banknote. The range of serial numbers, which is information for identifying a target set of banknotes from among the banknotes circulating in the market based on their serial numbers, may be specified, for example, by at least one of the first and last serial numbers of a sequence of serial numbers. The range of serial numbers may also be specified by some of the characters or numbers that make up the serial number. The version information, which is information indicating whether a banknote is new or old, may be the year of issue, the year of issue, or information indicating whether it is a current banknote or not. The version information may also be information that distinguishes banknotes whose design or security has been changed.
[0011] In the above configuration, the management device transmits the instruction information instructing the currency processing device to collect banknotes, and the currency processing device may collect the banknotes to be collected according to the instruction information by storing them in a predetermined storage section of the currency processing device, regardless of the identification result of the banknotes.
[0012] In the above configuration, the management device transmits the instruction information instructing the currency processing device to reject banknotes, and the currency processing device may reject banknotes that are subject to rejection based on the instruction information, regardless of the identification result of the banknotes.
[0013] In the above configuration, the management device transmits instruction information that instructs the currency processing device to change the processing content of banknotes, and the currency processing device may change the processing content of the currency processing device for the banknotes to be changed according to the instruction information and for other banknotes.
[0014] In the above configuration, the change in processing content may include at least one of the following: a change in the determination threshold for banknotes used for banknote identification, a change in the banknote transport speed, and a change in the banknote transport path.
[0015] In the above configuration, the banknote information may include at least one of the following: information regarding the identification result of the rejected banknote, information regarding the physical quantity obtained from the rejected banknote, information regarding the transport status of the rejected banknote, and information regarding the soiling status of the rejected banknote. The information regarding the identification result may include at least one of the following: currency, denomination, new / old, genuine / false, and correct / damaged. The information regarding the physical quantity may include at least one of the following: width, length, shape, and thickness of the banknote. The information regarding the transport status may include at least one of the following: skew, double feed, and chaining. The information regarding the soiling status may include at least one of the following: dirt, tear, and fold.
[0016] In the above configuration, the currency processing device that transmits the currency information further transmits device information, which is information about the currency processing device, to the management device, and the device information may include at least one of the following: information about the installation location of the currency processing device, information about the specifications of the currency processing device, and information about the sensors provided by the currency processing device. The installation location information may include at least one of the following: the name of the area where the currency processing device is installed, the address, the name of the store, or the name of the floor. The specifications information may include at least one of the following: the model number of the currency processing device, the serial number, or the software version. The sensor information may include at least one of the following: the model number of the sensor, the serial number, the software version, or the detection result by the sensor.
[0017] In the above configuration, the management device may be implemented by the functions of the currency processing device. That is, the currency processing device may function as a management device in place of or in addition to performing currency processing.
[0018] The currency processing device according to this disclosure includes a communication unit for transmitting information to a management device that manages information regarding rejected banknotes, a banknote processing unit for performing banknote processing, and a control unit for transmitting, via the communication unit, banknote information including the serial number of the rejected banknotes that the banknote processing unit has performed and rejected, and information obtained when identifying the rejected banknotes, to the management device.
[0019] The currency management device according to this disclosure comprises a communication unit for receiving information from a currency processing unit, a storage unit for storing information about rejected banknotes, and a control unit that receives, via the communication unit, the serial numbers of rejected banknotes rejected by the currency processing unit when it performs banknote processing, and banknote information including information acquired when identifying the rejected banknotes, and manages the banknote information in association with the serial numbers.
[0020] The currency management method relating to this disclosure includes the steps of: a currency processing device performing banknote processing; the currency processing device transmitting to a management device the serial numbers of rejected banknotes rejected during the execution of banknote processing, and banknote information including information obtained when identifying the rejected banknotes; and the management device managing the banknote information received from the currency processing device in association with the serial numbers.
[0021] According to the currency management system, currency processing device, currency management device, and currency management method disclosed herein, information regarding rejected banknotes, which has not been used conventionally, can be used in association with their serial numbers.

Figure 2 is a diagram showing an example of the configuration of a banknote processing device. Figure 3 is a diagram showing an example of information regarding rejected banknotes used in the currency management system. Figure 4 is a flowchart showing an example of the processing flow for rejected banknotes performed in the currency management system. Figure 5 is a flowchart showing another example of the processing flow for rejected banknotes performed in the currency management system.
[0023] Hereinafter, embodiments of the currency management system, currency processing system, currency management device, and currency management method according to this disclosure will be described with reference to the attached drawings. Figure 1 is a diagram illustrating the outline of the currency management system 1 according to this embodiment. The currency to be processed by the currency management system 1 may be banknotes, coins, or both banknotes and coins, but the following explanation will continue using banknotes as an example.
[0024] [Overview of the Currency Processing System] The currency management system 1 includes a management device (currency management device) 10 and a currency processing device 20 that is communicatively connected to the management device 10. For example, a computer device having a control unit, a storage unit and a communication unit may be used as the management device 10. It is also possible to use a currency processing device other than the currency processing device 20 as the management device 10. A currency processing device configured to realize the functions of the management device 10 in lieu of or in addition to performing currency processing may be used as the management device 10. For example, a currency processing device 20 called a front machine may be installed at the checkout counter of a store, and another currency processing device called a back machine may be installed in the back office, and the back machine may be used as the management device 10. For example, a currency processing device 20 called a teller machine may be installed at the counter of a financial institution, and another currency processing device installed behind the counter may be used as the management device 10.
[0025] The currency processing device 20 performs currency processing, including deposit processing. Deposit processing involves identifying and counting banknotes (coins) deposited into the currency processing device 20 from outside the device, storing them in the storage section, and outputting the total amount of stored banknotes as the deposit amount. The currency processing device 20 may also perform other banknote processing (currency processing), such as withdrawal processing, which involves dispensing banknotes for an instructed withdrawal amount.
[0026] During deposit processing, the currency processing device 20 takes in banknotes received from outside the device and identifies them while transporting them along a transport path provided inside the device. The currency processing device 20 uses various sensors to read the serial number (currency identification information) of the banknotes and acquire information about the banknotes. For example, the currency processing device 20 uses multiple types of sensors, such as optical sensors, magnetic sensors, and mechanical sensors, to identify the denomination and authenticity of the banknotes based on various features obtained from the banknotes. The currency processing device 20 may also identify whether the banknotes are genuine or damaged based on the various features.
[0027] The denomination of banknotes identified by the currency processing device 20 may include currency information such as Japanese yen, US dollars, for example, a 1,000 yen note. The denomination of banknotes identified by the currency processing device 20 may also include version information regarding the newness or age of the banknotes. The version information may be information indicating the year or era of issue of the banknote, information distinguishing banknotes with changed designs or security, such as Japanese banknotes such as D series and E series, or information indicating whether a banknote is current or not, such as a current 1,000 yen note or an old 1,000 yen note.
[0028] The currency processing device 20 processes banknotes identified within the device based on the identification result. The currency processing device 20 stores banknotes that can be processed normally in the storage compartment within the device, while rejecting banknotes that cannot be processed normally and sending them out of the device. For example, banknotes that are too dirty or damaged to be identified as banknotes of any denomination or authenticity may be rejected due to identification errors. Banknotes may also be rejected due to transport errors such as skewed transport or double feeding where multiple banknotes are transported on top of each other. Note that the process of storing banknotes that can be processed normally (normal banknotes) in the storage compartment is an example and does not limit the processing of normal banknotes.
[0029] As shown in Figure 1, the management device 10 collects information on banknotes rejected by each currency processing device 20 (rejected banknotes) (A). The information collected by the management device 10 includes currency information of the rejected banknotes. The information collected by the management device 10 may also include device information.
[0030] The monetary information is information about rejected banknotes. The monetary information is information obtained by the monetary processing device 20 from rejected banknotes. The monetary information includes the serial number of the banknote. It is also possible that the monetary information does not include the serial number, and the management device 10 obtains both the serial number and the monetary information. The monetary information may include information about identification results such as denomination, authenticity, and whether the banknote is genuine or damaged. The monetary information may include information about the physical quantities of the banknote, such as width, length, thickness, and shape. The monetary information may include information about the transport condition of the banknote, such as skew or double feeding. The monetary information may include information about the condition of the banknote, such as dirt or tears.
[0031] The device information is information about the currency processing device 20 that processed the rejected banknotes. The device information may include information about the location where the rejected banknotes were processed, such as the area name and address indicating the installation location of the currency processing device 20. The device information may include specification information such as the model number and device number to identify the currency processing device 20. The device information may include at least one of the following: sensor information relating to sensors provided in the identification unit and transport path of the currency processing device 20, and information about detection results such as values and images detected by the sensors. The sensor detection results may include information about the processing environment for rejected banknotes, such as the temperature and humidity at the time the rejected banknotes were processed.
[0032] In the currency management system 1 according to this embodiment, the currency processing device 20 can transmit the serial number of a rejected banknote and information other than the serial number related to the rejected banknote to the management device 10. The information other than the serial number includes at least one of currency information and device information. Conventional currency processing devices may use the serial numbers of banknotes that have been identified as counterfeit or suspected of being counterfeit and rejected (hereinafter collectively referred to as "counterfeit bills"), but they did not use information on banknotes rejected for other reasons such as identification errors or transport errors. For example, if a banknote is rejected and then reprocessed by resolving the cause of the transport error, and as a result the banknote is not rejected and is processed normally, the serial number and information of this banknote are processed as information on a normal banknote. On the other hand, if a banknote is repeatedly rejected even after reprocessing and the machine processing is abandoned and it is managed manually, the currency processing device 20 discards the information obtained from this banknote and does not use it in relation to the fact or cause of the rejection.
[0033] The currency processing device 20 according to this embodiment can transmit information about rejected banknotes, along with their serial numbers, to the management device 10, regardless of the reason for rejection, such as counterfeit bills, identification errors, or transport errors. If the currency processing device 20 successfully reprocesses a banknote that was previously rejected during banknote processing, it can transmit information about this banknote to the management device 10 as information about a valid banknote and also as information about a rejected banknote. For example, the serial number of the banknote and various information obtained by the currency processing device 20 when the banknote was rejected may be transmitted to the management device 10 as information about a rejected banknote, while the serial number of the same banknote and various information obtained by the currency processing device 20 when the banknote was successfully processed may be transmitted to the management device 10 as information about a valid banknote. However, there are cases where the serial number of the banknote and the information obtained by the currency processing device 20 when the banknote was rejected are transmitted to the management device 10, while the information about when the banknote was successfully processed is not transmitted to the management device 10.
[0034] The management device 10 stores and manages the information collected from each currency processing device 20 in its storage unit (B). The management device 10 manages the currency information of rejected banknotes obtained from the currency processing device 20 in association with the serial number of the rejected banknote. The management device 10 can also manage the device information obtained from the currency processing device 20 in association with the serial number of the rejected banknote. For example, the management device 10 can register and manage information related to rejected banknotes, such as the serial number, currency information, and device information, in a rejected banknote database (hereinafter simply referred to as the "database"). For example, the management device 10 manages the database so that by referring to the database, it can identify information such as the number of times a banknote was rejected, the date and time of rejection, the reason for rejection, and the location, environment, and device at the time the banknote was rejected.
[0035] The management device 10 determines a change in the banknote handling method based on information obtained from the currency processing device 20, and notifies the currency processing device 20 of the banknote handling information (currency handling information) including the changes, as shown in Figure 1 (C). The handling information includes information indicating a change in the banknote processing content and information indicating a change in the settings related to banknote processing and identification. The management device 10 may send the information regarding the changed processing and settings only to the currency processing device 20 that sent the information about the rejected banknotes that caused the change, or it may distribute it to multiple currency processing devices, including the currency processing device 20.
[0036] For example, when the management device 10 receives the serial number of a rejected banknote from the currency processing device 20, it refers to the database based on this serial number to check whether the same banknote has been rejected in the past. If the number of times the same banknote has been rejected reaches a number set in advance as a threshold, the management device 10 decides to change the handling of this banknote and sends information about the changed handling to the currency processing device 20, which is the source of the rejection information.
[0037] If a banknote with the same serial number is processed again, the management device 10 sends information to the currency processing device 20 instructing it to change the banknote's transport route or destination. For example, when processing a banknote with the same serial number again, whether it identifies the banknote as one to be rejected or one that can be processed normally, information is sent to the currency processing device 20 instructing it to collect it in the collection unit within the device. The collection unit is a banknote storage unit provided within the currency processing device 20 to collect and store banknotes that are not to be reused so that they do not circulate in the market.
[0038] When the currency processing device 20 receives instruction information from the management device 10, if the serial number of a banknote read during the execution of the deposit process matches the serial number of a rejected banknote that has been instructed to be collected, the device does not reject the banknote even though it identifies it as a banknote to be rejected, but instead stores it in the collection unit for storage within the device. The deposit amount in this deposit process includes the amount of the banknote collected in the collection unit. This makes it possible for users (operators) of the currency processing device 20 to avoid situations where banknotes are repeatedly rejected when they try to deposit them into the device, and instead proceed with transactions that include the amount of the banknote in the deposit amount. Furthermore, even if a banknote that has been instructed to be collected is deemed a valid banknote after reprocessing following rejection, it will not be stored in the storage unit for valid banknotes, but will be collected in the collection unit.
[0039] When the management device 10 receives instruction information, the currency processing device 20 may have already reprocessed the rejected banknotes and completed the processing successfully. In this case, the banknotes will be collected in the collection unit when they are processed next. For example, a banknote that was rejected once during deposit processing may be processed successfully during reprocessing and stored in the storage unit, and the currency processing device 20 may complete the deposit processing. In this case, when the currency processing device 20 receives a collection instruction, for example, when it dispenses banknotes from the storage unit and performs a withdrawal process, it identifies the banknotes that it has been instructed to collect based on their serial numbers and collects them in the collection unit without dispensing them. In other cases, when performing other banknote processing such as currency exchange processing or a scrutiny process to examine banknotes in the storage unit, banknotes that have been dispensed from the storage unit and identified based on their serial numbers may also be collected in the collection unit.
[0040] The management device 10 may instruct the currency processing device 20 to change the method of processing banknotes in preparation for reprocessing rejected banknotes. For example, the management device 10 may instruct the device to change the transport speed to a slower speed. If a banknote is rejected due to a transport error during deposit processing, the currency processing device 20, having received instruction information from the management device 10, can reduce the transport speed and reprocess the banknote, increasing the likelihood that the banknote will be processed correctly. The transport speed, which has been changed to a slower speed, can be returned to its original speed after the deposit processing is completed. The currency processing device 20 may also recognize the completion of processing of rejected banknotes based on the serial number and return to the original transport speed during the deposit processing.
[0041] The management device 10 may instruct the currency processing device 20 to change the threshold used for identifying banknotes. The currency processing device 20 compares the feature quantities obtained from the banknotes with pre-prepared thresholds to determine whether or not they can be processed as normal banknotes, and rejects banknotes that cannot be processed as normal banknotes. If the currency processing device 20 receives instructions from the management device 10 during the deposit process and changes the identification threshold to make it easier to determine that the banknotes are normal, and reprocesses the rejected banknotes, the likelihood of the banknotes being processed normally increases. This makes it possible to perform a deposit process that includes the amount of banknotes that were initially rejected in the deposit amount.
[0042] Furthermore, the threshold change may be applied only to rejected banknotes. The currency processing unit 20 can recognize a banknote as rejected based on its serial number and change the banknote identification only for that banknote. Alternatively, the currency processing unit 20 may change the threshold only during the deposit process in which banknotes are rejected to identify all banknotes, and then return the threshold to its original value after the deposit process is completed.
[0043] The management device 10 may refer to information on multiple rejected banknotes registered in the database based on attributes such as the denomination and version information of the rejected banknotes, and decide to permanently change the threshold for identification. In this case, the management device 10 notifies all currency processing devices 20 constituting the currency management system 1 of the attributes such as the denomination and version information of the banknote whose threshold is to be changed, and the details of the change, and each currency processing device 20 can then change the threshold stored for identification.
[0044] For example, if the thickness is 0.10 mm or more, a discrimination threshold for rejecting banknotes is set. Assume that a large number of banknotes with a thickness of 0.11 mm are rejected. The management device 10 analyzes a database registering serial numbers, denominations, and rejection reasons. When it recognizes that rejection due to thickness shows a correlation with the range of serial numbers, it identifies the range of serial numbers where rejections frequently occur. When processing banknotes with serial numbers belonging to the identified range, the management device 10 transmits information instructing the currency processing device 20 to change the thickness threshold to 0.12 mm. For example, even when dealing with newly issued banknotes where the paper material and the ink used for printing are changed, resulting in an increase in the thickness obtained from the banknote during discrimination, the management device 10 can automatically change the thickness threshold to avoid a situation where normal banknotes are frequently rejected. Here, the range of serial numbers is information for specifying some banknotes from the banknotes in circulation in the market, such as, for example, 100 banknotes with serial numbers from "A0…001A" to "A0…100A", or all banknotes with the last digit of the serial number being "A". Also, banknotes belonging to the range of serial numbers mean that the serial number of this banknote is included in a plurality of serial numbers specified by the range of serial numbers.
[0045] Whether the management device 10 automatically executes the change of the discrimination threshold can be changed by setting. When set to not automatically change, in the above example, the management device 10 that recognizes that rejections frequently occur for banknotes with new serial numbers executes a notification process for notifying the necessity of changing the threshold. For example, information such as the range of serial numbers where rejections frequently occur, the recommended amount of change in the threshold, and the threshold after the change for avoiding rejections is notified to the user (operator) of the management device 10. Here, the users mentioned include, for example, the manufacturing company of the currency processing device 20 and the management company of the currency processing device 20. The notification can be performed by displaying the information on the display unit provided in the management device 10 or on the display unit of a terminal communicably connected to the management device 10. The user who receives the notification can check the notification content and decide whether to change the threshold.
[0046] The change in the thickness threshold of banknotes is for illustration purposes and does not limit the types of changeable thresholds. Other physical quantities used for banknote identification, such as the width, length, shape, etc. of banknotes, may also be changed. The attributes of banknotes for which the thresholds are changed are not limited to the range of serial numbers, and the thresholds may also be changed based on the denomination or version information.
[0047] The change of the threshold is not limited to the mode in which all the currency processing devices 20 constituting the currency management system 1 are targeted, and may also be the mode in which only some of the currency processing devices 20 are targeted. For example, using the device information, the threshold may be changed in some of the currency processing devices 20, such as the currency processing devices 20 installed in a certain area or the currency processing devices 20 equipped with a certain type of sensor. For example, the threshold may be changed in some of the currency processing devices 20, such as the currency processing devices 20 of the same model or the currency processing devices 20 of the same specification. After changing the threshold for only some of the currency processing devices 20, the mode of increasing the currency processing devices 20 targeted for the threshold change may also be adopted. For example, the threshold may be changed only for the currency processing devices 20 installed in a certain area, and then the area for the threshold change may be gradually expanded.
[0048] The currency processing device 20 is not limited to the mode of accepting the change in the threshold determined by the management device 10 as described above, and may be configured to be able to select whether to accept the change in the threshold. For example, the management device 10 or the currency processing device 20 may notify the user of the currency processing device 20 of the necessity of the threshold change, and the user may operate the operation unit provided in the currency processing device 20 to select whether to accept the change in the threshold. The currency processing device 20 may be configured such that the user of the currency processing device 20 can change the numerical value of the threshold after the change determined by the management device 10 to another numerical value. The user may operate the operation unit provided in the currency processing device 20 to change the threshold. The users mentioned here include, for example, the persons in charge of stores or financial institutions using the currency processing device 20. The persons in charge of the manufacturing company or management company of the currency processing device 20 may also be included among the users.
[0049] For example, in the above example where the management device 10 decides to change the banknote thickness threshold from 0.10 mm to 0.12 mm, if the user of the currency processing device 20 accepts the threshold change, the threshold of the currency processing device 20 will be changed to 0.12 mm as described above. On the other hand, if the user refuses the threshold change, the threshold of the currency processing device 20 will not be changed and will remain at 0.10 mm. If the user changes the threshold from 0.12 mm, which was determined by the management device 10, to 0.11 mm, the threshold of the currency processing device 20 will be changed from 0.10 mm to 0.11 mm.
[0050] Changes related to banknote identification are not limited to changes in thresholds, but may also involve changes in the settings related to identification. For example, the management device 10 may instruct changes to the type of sensor used for banknote identification, or to settings related to the function and operation of the sensor, such as the voltage value and current value that drive the sensor.
[0051] As shown in Figure 1, the management device 10 can provide information about rejected banknotes to an external device (D). The external device may include devices used by the manufacturer of the currency processing device 20, or devices used by the management company of the currency processing device 20. The external device may also include devices used by organizations that issue or print banknotes.
[0052] The information provided by the management device 10 includes the serial number of each rejected banknote and at least one of either currency information or device information. Users such as manufacturers and management companies can analyze the information provided by the management device 10 and use it to change the configuration or processing content of the currency processing device 20.
[0053] For example, if, based on information provided by the management device 10, it is determined that banknotes are more likely to be rejected by the currency processing device 20 installed in a coastal area, the user can change the settings and specifications of the device according to the installation area. For example, based on the period from when a banknote is issued until it deteriorates and becomes prone to rejection, the user can suggest to the central bank or printing bureau that issues the banknotes when to collect old banknotes from the market or when to reprint them, or suggest the conditions for banknotes that can be processed by the machine properly.
[0054] Similar to the proposed change in the identification threshold described above, the management device 10 can also be configured to transmit changes to the banknote processing content, changes to the settings of the device and sensors, and conditions favorable for next-generation banknotes to an external device and notify the user of the external device. For example, the management device 10 can be configured to analyze the information registered in the database using statistical methods, machine learning, AI technology, etc., and to make various suggestions based on the analysis results. Similar to the proposal for changing the threshold, the management device 10 can display the suggested content on a display device or communication terminal to show it to the user, allowing the user to consider and use the suggested content.
[0055] Although Figure 1 mainly illustrates an example of using information on rejected banknotes, the management device 10 can also acquire and manage information on banknotes that have been processed normally by each currency processing device 20. Based on the comparison results between the information on normal banknotes and the information on rejected banknotes, the management device 10 can execute the above-mentioned processes. For example, based on the results of statistical processing comparing the physical quantities acquired from normal banknotes and rejected banknotes, the management device 10 can make various suggestions, such as changing the threshold for banknote identification or changing the processing content of banknote processing.
[0056] [Configuration of the Currency Processing Device] Figure 2 shows an example of the configuration of the banknote processing device 200. The banknote processing device 200 is an example of the currency processing device 20 described in Figure 1. Figure 2(a) is a schematic cross-sectional view showing the general internal configuration of the banknote processing device 200. Figure 2(b) is a block diagram showing the general functional configuration of the banknote processing device 200.
[0057] As shown in Figure 2(a), the banknote processing device 200 receives banknotes from the outside into the deposit unit 210, identifies them with the identification unit 240, stores normal banknotes in the storage unit 250, and rejects rejected banknotes from the reject unit 220. This type of banknote processing is sometimes called deposit processing. The transport of banknotes along the transport path within the device is performed by the transport unit 260. The banknote processing device 200 may also perform a counting process in which, after identifying and counting banknotes in the same way as deposit processing, it dispenses normal banknotes from the dispensing unit 230 without storing them in the storage unit 250. The banknote processing device 200 may not have a reject unit 220, and the dispensing unit 230 may also perform the function of the reject unit 220. Figure 2 shows only one storage unit 250, but the number of storage units 250 is not limited, and for example, banknotes may be stored in multiple storage units 250 according to their denomination.
[0058] The banknote processing device 200 dispenses banknotes stored in the storage unit 250, transports them using the transport unit 260, identifies them using the identification unit 240, and then performs a dispensing process to discharge them to the outside of the device from the dispensing unit 230. Alternatively, the banknote processing device 200 may store the serial numbers and denominations of banknotes identified by the identification unit 240 and stored in the storage unit 250, associating them with the storage order, and during the dispensing process, may use the stored serial number and denomination information without performing identification by the identification unit 240.
[0059] For example, using the banknote processing device 200 installed in a store, a transaction is conducted with the customer based on the total amount of normal banknotes (deposit amount) obtained by performing a deposit process, and a withdrawal process is performed to return banknotes corresponding to the change amount (withdrawal amount) to the customer as needed. Also, for example, using the banknote processing device 200 installed in a financial institution, a deposit process is performed to deposit the deposit amount into the customer's account, and a withdrawal process is performed to dispense banknotes corresponding to the withdrawal amount withdrawn by the customer from their account.
[0060] As shown in Figure 2(b), the banknote processing device 200 includes a banknote processing unit 140, which includes the components shown in Figure 2(a), as well as a control unit 100, an operation display unit 110, a storage unit 120, and a communication unit 130.
[0061] The operation display unit 110 functions as a display unit that displays information related to banknote processing. The operation display unit 110 also functions as an operation unit for inputting information related to banknote processing. For example, a touch panel type liquid crystal display device is used as the operation display unit 110. The storage unit 120 is a non-volatile storage device that stores various information necessary for the operation of the banknote processing device 200. The communication unit 130 is a communication interface used to send and receive various information with the management device 10.
[0062] The control unit 100 controls each part of the banknote processing device 200. For example, a program corresponding to the control unit 100 is pre-stored in the storage unit 120 or a dedicated storage device, and the functions and operations of the control unit 100 are realized when this program is executed by hardware such as a CPU. The functions and operations of the banknote processing device 200 described in this embodiment are realized when the control unit 100 controls each part based on information input and output via the operation display unit 110, information transmitted and received via the communication unit 130, and information stored in the storage unit 120. In this embodiment, the functions and operations of the banknote processing device 200 realized by the control unit 100 may be simply described as the functions and operations of the banknote processing device 200.
[0063] The identification unit 240 includes multiple types of sensors, such as a transport sensor 241, a mechanical sensor 242, an optical sensor 243, and a magnetic sensor 244. The transport sensor 241 detects the position of banknotes passing through the identification unit 240. Based on the detection result from the transport sensor 241, each sensor acquires feature quantities from the banknotes.
[0064] For example, the mechanical sensor 242 includes a thickness sensor that detects the thickness of a banknote based on the vertical movement of the rollers as the banknote passes between them. The optical sensor 243 detects the optical features of the banknote. For example, the optical sensor 243 includes an image sensor that captures images of one or both sides of the banknote. The serial number of the banknote is read based on the banknote image acquired by the image sensor. The banknote image is also used to identify the denomination, authenticity, and condition of the banknote. The banknote image may also be used to detect physical quantities such as the width and length of the banknote. The optical sensor 243 may be used as a thickness sensor that detects the thickness of the banknote based on the amount of light transmitted by irradiating light from one side of the banknote and receiving the transmitted light on the other side, or it may be used to detect the transport state. The magnetic sensor 244 detects the magnetic features of the banknote. For example, if the banknote contains magnetic ink or magnetic threads, these are detected by the magnetic sensor 244.
[0065] The transport unit 260 includes a transport sensor 261, a transport mechanism 262, a branching mechanism 263, and a drive unit 264. One or more transport sensors 261, installed along the transport path, detect the position of the banknotes being transported along the transport path. Based on the detection results from the transport sensors 261, the banknote branching mechanism 263 is controlled to change the destination of the banknotes. The transport sensors 261 may also be used to detect the length and width of the transported banknotes, or to detect transport abnormalities such as skew or double feeding.
[0066] The transport mechanism 262 includes at least one of a belt and / or rollers provided in the transport path, and transports banknotes along the transport path by rotating the belt or rollers. The branching mechanism 263 includes branching claws provided at points where the transport path branches into multiple paths, and the destination of the banknotes is switched by rotating the pivotally supported branching claws. The drive unit 264 is an actuator that drives the transport mechanism 262 and the branching mechanism 263. For example, the motor of the drive unit 264 rotates the belt or rollers of the transport mechanism 262 to transport banknotes, and the solenoid of the drive unit 264 rotates the branching claw of the branching mechanism 263 to switch the destination of the banknotes.
[0067] Note that the configuration shown in Figure 2(b) is illustrative and does not limit the configuration of the identification unit 240. For example, the identification unit 240 may not include some of the sensors described above, or it may include sensors other than those described above, such as an ultrasonic sensor. Similarly, Figure 2(b) does not limit the configuration of the transport unit 260. The banknote processing device 200 may be equipped with sensors that detect temperature and humidity during banknote processing, either in the identification unit 240 or the transport unit 260, or separately from the identification unit 240 and the transport unit 260.
[0068] The banknote processing device 200 uses the sensors of the identification unit 240 to read the serial numbers of banknotes being transported by the transport unit 260, and identifies the banknotes based on the characteristic quantities obtained from the banknotes. The banknote processing device 200 detects the transport status using the sensors provided in the identification unit 240. The banknote processing device 200 can detect identification abnormalities and transport abnormalities using the sensors 241 to 244 provided in the identification unit 240. The banknote processing device 200 may also detect transport abnormalities using the transport sensor 261 provided in the transport unit 260. The banknote processing device 200 may also detect transport abnormalities based on changes in the load on the drive unit 264 such as a motor, or the transport mechanism 262 such as rollers or belts.
[0069] The banknote processing device 200, for example, when performing a deposit process, stores normal banknotes in the storage unit 250, while rejecting banknotes for which identification or transport abnormalities have been detected from the rejection unit 220. The banknote processing device 200 transmits information regarding the rejected banknotes to the management device 10 via the communication unit 130.
[0070] [Information about rejected banknotes] Figure 3 shows an example of information about rejected banknotes used in the currency management system 1. Figure 3(a) shows information about rejected banknotes that the banknote processing device 200 transmits to the management device 10. Figure 3(b) shows an example of a database of rejected banknotes managed by the management device 10. In this embodiment, an example is described in which the management device 10 registers various information about rejected banknotes in the database shown in Figure 3(b), but this is an example and does not limit the method of information management by the management device 10. As long as the management device 10 can recognize the correspondence between each piece of information and related information, the method of handling information by the management device 10 is not particularly limited, and for example, the management device 10 may store each piece of information individually.
[0071] The banknote processing device 200 transmits rejection information for each rejected banknote, as shown in Figure 3(a). The rejection information includes the serial number of the rejected banknote, the date and time of rejection, banknote information, and device information. The banknote information includes identification information and status information. The device information includes specification information, sensor information, and location information.
[0072] Identification information is information obtained when identifying rejected banknotes. This identification information includes physical information such as the width, length, shape, and thickness of the rejected banknote, and identification information including the denomination, authenticity, and condition. The denomination information may also include currency and version information.
[0073] Status information is information obtained when identifying or transporting rejected banknotes. Status information includes transport information regarding the transport condition of rejected banknotes, such as skew, double feeding, chaining, jamming, etc., and damage information regarding the degree of damage to rejected banknotes, such as dirt, tears, folds, etc. Double feeding refers to a state in which at least a portion of two or more banknotes are transported overlapping. Chaining refers to a state in which the transport unit 260 normally transports two consecutive banknotes with a predetermined interval, but the interval between two consecutive banknotes is smaller than the predetermined interval. Jamming refers to a jam of banknotes.
[0074] The specification information concerns the specifications of the banknote processing device 200. The specification information includes the model number of the banknote processing device 200, the serial number to distinguish each device, and the firmware and software versions of the banknote processing device 200. The specification information may also include information concerning the specifications of the motor, rollers, belts, etc. that constitute the transport unit 260, or it may include information indicating the load generated on the drive unit 264 such as the motor, or the transport mechanism 262 such as the rollers and belts.
[0075] Sensor information refers to information about the sensors used to identify rejected banknotes. Sensor information includes the model number of each sensor provided by the identification unit 240 and the transport unit 260, the manufacturing number to distinguish each sensor, the firmware and software version of the sensor, the sensor type indicating the type of sensor, and the detection results such as the detected value obtained by each sensor and the banknote image. Sensor information may also include other information about the sensor, such as the voltage value and current value that drive the sensor, and the brightness and lightness of the light source used by the sensor. If the banknote processing device 200 is equipped with a temperature sensor and a humidity sensor, the detection results will include temperature and humidity information.
[0076] Location information refers to the location where the rejected banknotes were processed, i.e., the location of the banknote processing device 200 that rejected the banknotes. Location information includes area information, such as the area name and address, to identify the area (region) where the banknote processing device 200 is installed, and store information to identify the store or floor name where the banknote processing device 200 is installed.
[0077] If a rejected banknote occurs during banknote processing, the banknote processing device 200 transmits the rejection information shown in Figure 3(a) to the management device 10. However, the rejection information shown in Figure 3(a) is illustrative and does not limit the information that the banknote processing device 200 transmits to the management device 10. The rejection information may not include some of the information shown in Figure 3(a), or it may include information not shown in Figure 3(a). The rejection information may include information indicating the cause of rejection, such as identification errors or transport errors, or it may include information indicating the type of sensor or output value that caused the identification error or transport error.
[0078] The management device 10 registers and manages the rejection information received from each banknote processing device 200 in a database (rejected banknote database), as shown in Figure 3(b). Rejected banknotes are managed based on their serial numbers. By referring to the database, it is possible to identify the date and time the banknote was rejected, the banknote information obtained at the time of rejection, and the device information of the banknote processing device 200 that rejected the banknote. For example, it is possible to identify the elapsed time since the first rejection of a banknote and the cumulative number of rejections.
[0079] [Processing of rejected banknotes] Figure 4 is a flowchart showing an example of the processing flow for rejected banknotes performed in the currency management system 1. When a rejected banknote occurs in the banknote processing device 200 in a standby state (step S1; No), the banknote processing device 200 transmits the reject information shown in Figure 3(a) to the management device 10 (step S2). Note that although we are focusing on the processing of rejected banknotes here, the state is described as a standby state, which means that the banknote processing device 200 is in the process of processing banknotes, continuing to process normal banknotes while waiting for the occurrence of rejected banknotes.
[0080] When the management device 10 is in standby mode (Step S3; No), upon receiving rejection information (Step S3; Yes), it registers the data of the rejected banknote in the database shown in Figure 3(b) and determines whether information for a banknote with the same serial number, i.e., the same banknote, is registered in the database (Step S4). If there is no information for the same banknote in the database (Step S4; No), the management device 10 returns to standby mode (Step S3; No).
[0081] If rejection information for the same banknote has been registered in the database in the past (Step S4; Yes), the management device 10 determines whether the number of rejections for this banknote satisfies the pre-prepared handling change conditions (Step S5). The handling change conditions are set to change the handling of the banknote when the number of rejections reaches a predetermined threshold number. If the handling change conditions are met (Step S5; Yes), the management device 10 sends handling information instructing the handling of the rejected banknote to the banknote processing device 200 that sent the rejection information (Step S6). The management device 10 may also send the handling change instruction information to a banknote processing device 200 other than the sender of the rejection information (Step S6).
[0082] The banknote processing device 200 that has rejected a banknote can change the handling of the rejected banknote if the number of rejections reaches a threshold number, according to the instructions of the control device 10 (step S7). For example, as explained in Figure 1, if the rejected banknote is reprocessed during the deposit process in which the banknote was rejected, the banknote processing device 200 can collect the banknote in the collection unit without rejecting it, regardless of whether the identification unit 240 determines that it should be rejected or whether it determines that it is a normal banknote. For example, the banknote processing device 200 can also reprocess the banknote by reducing the transport speed or relaxing the identification threshold.
[0083] In some cases, rejected banknotes may not be reprocessed by the banknote processing device 200 that sent the rejection information for the banknote. For example, a user depositing banknotes into a banknote processing device 200 installed in a store may deposit other banknotes instead of re-depositing the rejected banknotes, thus completing the deposit process. Even in such cases, information instructing a change in the handling of this banknote is distributed to banknote processing devices 200 other than the one that sent the rejection information. Therefore, when the customer deposits this banknote into another banknote processing device 200, the device that changed the handling can retrieve the banknote into the device or process it by changing the transport speed or identification threshold (step S8).
[0084] The handling information instructing a change in the handling of banknotes may be transmitted simultaneously to the banknote processing device 200 that is the source of the rejection information and to the other banknote processing devices 200, or it may be transmitted with a time delay. For example, the management device 10 may first transmit the handling information only to the banknote processing device 200 that is the source of the rejection information, and if it receives information from this banknote processing device 200 indicating that the collection of the relevant banknotes has been completed, it may not transmit the handling information to the other banknote processing devices 200. In this case, for example, after transmitting the handling information, if a predetermined time has elapsed and information indicating that collection has been completed has not been received, the handling information may be transmitted to the other banknote processing devices 200 as well. The banknote processing device 200 may periodically transmit information regarding rejected banknotes to the management device 10, and the management device 10 may decide whether or not to transmit the handling information to the other banknote processing devices 200 based on the information received from the banknote processing device 200.
[0085] If the number of rejections does not satisfy the handling change condition (Step S5; No), the management device 10 further determines whether the elapsed time satisfies the handling change condition (Step S9). The handling change condition is set to change the handling of a banknote when the elapsed time since the first rejection of the banknote reaches a predetermined threshold time. If the handling change condition is met (Step S9; Yes), similar to the case where the handling change condition for the number of rejections is met, handling information instructing the handling of the rejected banknote is sent to the banknote processing device 200 that is the source of the rejection information and to the other banknote processing devices 200 (Step S10). In this case as well, similar to the example described above, the handling information may be sent to multiple devices simultaneously or with a time difference.
[0086] Upon receiving an instruction to change handling procedures, the banknote processing device 200 and other banknote processing devices can change the handling procedures according to the instruction (steps S7, S8). For example, if the control device 10 instructs the collection of banknotes, the banknote processing device 200 or other banknote processing device that processed the banknotes will collect them.
[0087] The conditions for changing the handling of an application can be set to change the handling when a single condition is met, such as when the number of rejections reaches a predetermined number, or when a predetermined amount of time has elapsed since the first rejection, or when multiple conditions are met.
[0088] For example, the system can be configured to change the handling of a banknote when the number of rejections reaches a predetermined number and the elapsed time since the first rejection reaches a predetermined time. Alternatively, as shown in Figure 3, the system can be configured to change the handling of a banknote when the number of rejections at a device installed in a coastal area reaches a threshold number, using information about the area name registered in the database of rejected banknotes. In this case, even if the number of banknote rejections reaches the threshold number, the handling will not be changed if the cumulative number of rejections at the banknote processing device in the coastal area has not reached the threshold number.
[0089] The handling change conditions can be set by specifying at least one piece of information from the various pieces of information shown in Figure 3(a), and specifying how the banknote handling method should be changed when each piece of information satisfies certain conditions. Alternatively, at least one piece of information from the device information shown in Figure 3(a) can be used to specify the banknote processing device 200 that will change the banknote handling method.
[0090] In Figure 4, an example is shown in which the banknote processing device 200 changes the processing of rejected banknotes based on handling information received from the management device 10. However, as explained in Figure 1, the banknote processing device 200 is configured to allow the user to choose whether or not to accept the change decided by the management device 10, and the user of the banknote processing device 200 may refuse the change. In this case, the banknote processing device 200 will perform the banknote processing without changing the processing content.
[0091] [Another Processing Method for Rejected Banknotes] Figure 5 is a flowchart showing an example of an alternative processing method for rejected banknotes performed in the currency management system 1. When a rejected banknote occurs in the banknote processing device 200, which is in a standby state (step S11; No), the banknote processing device 200 transmits the rejection information shown in Figure 3(a) to the management device 10 (step S12). Similar to the case in Figure 4, the standby state is used because the focus is on the processing of rejected banknotes. This means that the banknote processing device 200 is waiting for the occurrence of rejected banknotes while continuing to process normal banknotes during the execution of banknote processing.
[0092] When the management device 10 is in standby mode (step S13; No), upon receiving rejection information (step S13; Yes), it registers the data of the rejected banknotes in the database shown in Figure 3(b). When the database is updated, the management device 10 performs a statistical analysis to examine the correlation of the data registered in the database (step S14) and determines whether or not there is significance (step S15).
[0093] If statistical analysis results showing significance are not obtained (Step S15; No), the control device 10 returns to the standby state (Step S13; No). On the other hand, if statistical analysis results showing significance are obtained (Step S15; Yes), the control device 10 decides to change the handling method for banknotes having the same attributes as rejected banknotes. The control device 10 transmits handling information instructing the change in banknote handling to the banknote processing device 200, which is the source of the rejected information, and to other banknote processing devices (Step S16).
[0094] Each banknote processing device 200 that receives an instruction from the management device 10 can change its handling of banknotes according to the instruction (step S17). Other banknote processing devices 200 that receive an instruction can similarly change their handling of banknotes according to the instruction (step S18). All banknote processing devices 200 that constitute the currency management system 1 can change their handling of banknotes upon receiving an instruction from the management device 10.
[0095] The management device 10 changes the handling of banknotes when it finds a correlation between the data registered in the database of rejected banknotes. For example, if the reason for rejecting a banknote by the banknote processing device 200 is the thickness of the banknote, the management device 10 statistically analyzes the data of the same denomination as the rejected banknote to see if factors other than thickness are related to the reason for rejection (step S14). If, as a result, it is found that there are many rejections due to abnormal thickness for banknotes whose serial numbers belong to a certain range, the management device 10 determines that this is significant (step S15; Yes), and sends handling information instructing a change in the thickness threshold for banknotes belonging to this serial number range to all banknote processing devices 200 belonging to the currency management system 1, for example, as explained in Figure 1 (step S16). Each banknote processing device 200 processes the banknotes based on the instruction (steps S17, S18), thereby suppressing the frequent rejections due to abnormal thickness.
[0096] In some cases, a correlation can be found between the reason for rejection and multiple factors. For example, in the above example, if it is discovered that banknotes with serial numbers belonging to a certain range are being rejected by a currency processing device installed in a certain area along the coast, the management device 10 transmits handling information to the currency processing device in the relevant area instructing a change in the thickness threshold for banknotes belonging to that serial number range. In this case, the same banknote will be identified using different thresholds by the currency processing device that receives the instruction information and by other devices.
[0097] The management device 10 can perform statistical analysis on each piece of information shown in Figure 3(a), select at least one piece of information that shows significance, and set how the banknote handling method should be changed under what conditions each piece of information satisfies. It can also specify a banknote processing device 200 that changes the banknote handling method using at least one piece of information from the device information shown in Figure 3(a).
[0098] In Figure 5, an example is shown in which the banknote processing device 200 changes the banknote processing content based on handling information received from the management device 10. However, as explained in Figure 1, the banknote processing device 200 is configured to allow the user to choose whether or not to accept the changes determined by the management device 10, and the user of the banknote processing device 200 may refuse the changes. In this case, the banknote processing device 200 will perform banknote processing without changing the processing content. In addition, the user of the banknote processing device 200 may change the banknote processing method determined by the management device 10, such as changing the threshold determined by the management device 10. In this case, the banknote processing device 200 will perform banknote processing according to the changes made by the user.
[0099] Figure 5 illustrates an example in which the management device 10 decides whether or not to change the banknote handling method after receiving rejection information from the banknote processing device 200. However, this is merely an example and does not limit the timing of the decision to change. The management device 10 may decide whether or not to change the banknote handling method after the number of rejected banknote entries registered in the database reaches a predetermined threshold. For example, the processing from step S14 onwards shown in Figure 5 may be executed each time the number of newly registered rejected banknote entries in the database reaches a predetermined number (e.g., 1000). The management device 10 may also decide whether or not to change the banknote handling method after a predetermined period of time has elapsed. For example, the processing from step S14 onwards shown in Figure 5 may be executed each time a predetermined period of time (e.g., one month) has elapsed.
[0100] In this embodiment, we have described an example in which rejected banknotes are distinguished based on their serial numbers, which are currency identification information, and various information is managed as shown in Figure 3. However, if each coin can be distinguished by its currency identification information, the currency management system 1 can perform the above-described processes on the coins.
[0101] The configuration of the currency management system 1 described in this embodiment is functionally general, and the configuration of the currency management system 1 is not physically limited to this configuration. The form of distribution and integration of each device is not limited to the example described above, and all or part of them can be functionally or physically distributed and integrated in any unit according to various loads and usage conditions.
[0102] While embodiments of the currency management system according to this disclosure have been described above with reference to the drawings, the configuration and operation of the currency management system and each of its constituent devices are not limited to the above embodiments, and may be implemented in various ways based on the knowledge of a person skilled in the art, without departing from the spirit of the invention.
