The operation display unit 6 is integrated with an LCD (Liquid Crystal Display) that displays an operation screen at the time of transaction and a touch panel for selecting a transaction type, inputting a personal identification number, transaction amount, and the like.

  The numeric keypad 7 is a physical key that accepts input of numbers such as “0” to “9”, and is used at the time of input operation such as a password or transaction amount. The receipt issuing port 8 is a part that issues a receipt on which transaction details are printed at the end of transaction processing. Incidentally, a receipt processing unit (not shown) for printing transaction contents and the like on the receipt is provided on the back side of the receipt issuing port 8.

  In the housing 2, a main control unit 9 that performs overall control of the entire automatic cash transaction apparatus 1, a banknote depositing and dispensing machine 10 that performs various processes related to banknotes, and the like are provided. The main control unit 9 is mainly configured by a CPU (Central Processing Unit) (not shown), and has a predetermined value from a storage unit 30 including a ROM (Read Only Memory), a RAM (Random Access Memory), a hard disk drive, a flash memory, and the like. By reading and executing the program, each unit is controlled to perform various processes such as deposit transactions and withdrawal transactions.

  In the following, the side of the automated teller machine 1 facing the customer is the front side, the opposite is the rear side, the left and right sides are the left side and the right side as viewed from the customer facing the front side, and the upper side and the lower side. Is defined and explained.

[1-2. Configuration of banknote deposit and withdrawal machine]
As shown in FIG. 2, the banknote depositing / dispensing machine 10 is configured such that the control unit 12 includes each unit (the depositing / dispensing unit 16, the transport unit 24, the discrimination unit 18, the temporary storage unit 20, the forgotten storage 22, the banknote storage 26 and the reject storage 28).

  The control unit 12 is mainly configured by a CPU (not shown), and reads and executes a predetermined program from the storage unit 14 including a ROM, a RAM, a hard disk drive, a flash memory, and the like, thereby controlling each unit and performing a deposit transaction. And various processes such as withdrawal transactions.

  Inside the banknote depositing / dispensing machine 10, a depositing / withdrawing unit 16, an identification unit 18 for judging the denomination and authenticity of the banknote, a temporary holding unit 20 for temporarily retaining deposited banknotes, and a customer at the time of transaction. A forgotten storage 22 or the like for collecting and storing banknotes forgotten from the deposit / withdrawal unit 16 is provided.

  The deposit / withdrawal unit 16 separates banknotes input from the customer one by one and feeds them to the transport unit 24. The transport unit 24 transports rectangular banknotes in the short direction along a transport path indicated by a thick line in the drawing by a roller, a belt, or the like (not shown). The conveyance part 24 conveys a banknote so that the discrimination part 18 may be penetrated in the front-back direction, and has connected the back side of the said discrimination part 18, the forgetting storage 22, the temporary storage part 20, and the deposit or withdrawal part 16, respectively. . Moreover, the conveyance part 24 has connected the front side of the discrimination part 18, and the deposit or withdrawal part 16, the banknote storage 26, and the rejection store | warehouse 28. FIG.

  The discriminating unit 18 discriminates the denomination and authenticity of the banknote, the degree of damage (correctness), etc. using the optical element, the magnetic detection element, etc. while conveying the banknote, and the discrimination result is obtained. Notify the control unit 12. Moreover, the discrimination part 18 gives the serial number which is the banknote identification information comprised by the alphanumeric character etc. which were provided for every banknote BL as shown in FIG. 3, and was previously printed on the one surface of the banknote from the image data of the imaged banknote. Read identify. At this time, the discrimination unit 18 notifies the control unit 12 of the identified character as an identification result. In response to this, the control unit 12 determines the transport destination of the banknote based on the acquired discrimination result and identification result.

  Moreover, the identification part 18 performs the serial number registration process mentioned later, and as shown in FIG. 6, the serial number information containing the serial number identification result for every banknote is the number of the banknotes taken in into the banknote depositing / withdrawing machine 10. The serial number information list LIID shown in the list side by side is created and registered in the built-in storage unit.

  As shown in FIG. 3, the banknote BL has a first serial number ID1 at the first serial number position P1 at the upper left and a second serial number ID2 at the second serial number position P2 at the lower right. In the case of a normal banknote, the first serial number ID1 and the second serial number ID2 are the same character string. However, for example, in the case of a counterfeit ticket, the first serial number ID1 and the second serial number ID2 do not necessarily match and may be different character strings. Thus, the serial number is arranged at a plurality of positions (for example, two places) on the banknote.

  The serial number is composed of, for example, English characters such as alphabets and numbers 0 to 9. This serial number is stored when the banknote is jammed inside the automated teller machine 1 or when the automated teller machine 1 takes in a banknote that the customer forgets to take, etc. It is used when bills are identified from the number identification result and presented to the customer as evidence information. In addition, when a counterfeit ticket is found in the automatic teller machine 1, the serial number collates the serial number of the counterfeit ticket with the stored serial number identification result and transaction information, and the process of depositing into the automatic teller machine 1 Or banknotes deposited by the customer, it is used when presenting to the customer as evidence information. Furthermore, serial numbers have forged tickets distributed in large quantities, and when the serial numbers of those counterfeit tickets are specified, the serial numbers are registered in the discrimination unit 18 in advance, and the number of characters of a certain number or more is registered. It is also used when detecting a matched bill as a forged ticket.

  The temporary holding unit 20 temporarily holds banknotes inserted by the customer into the depositing / withdrawing unit 16 at the time of depositing, and temporarily holds the normal banknotes identified as depositable by the discrimination unit 18 until the deposit is confirmed.

  Further, inside the banknote depositing / dispensing machine 10, a banknote 26 of each denomination, a banknote discriminated from a banknote (so-called damaged banknote) damaged in the discrimination section 18, a banknote identified as a forged ticket, and 5 A reject box 28 for storing denominated banknotes that are not returned, such as thousand or 2,000 tickets, is provided. The banknote storage 26 takes in and stores the banknotes transported from the transport unit 24 by the storage and discharge mechanism, and discharges the stored banknotes and supplies them to the transport unit 24.

  In this configuration, in the automatic teller machine 1, the main control unit 9 and the control unit 12 control each unit based on the banknote discrimination result and the identification result by the discrimination unit 18, and the banknote depositing process, the storing process and the banking process are performed. Perform gold processing.

  That is, in the automatic teller machine 1, when a deposit transaction is selected by the customer via the operation display unit 6 at the time of deposit transaction and a bill is inserted into the deposit / withdrawal port 5, the inserted bill is transferred from the deposit / withdrawal unit 16. One by one is conveyed to the discrimination unit 18. Here, the automatic teller machine 1 conveys the banknote determined to be depositable based on the discrimination result and the identification result of the discrimination unit 18 to the temporary storage unit 20 and temporarily stores it. On the other hand, the automatic teller machine 1 returns the banknote determined to be unsuitable for depositing to the depositing / dispensing unit 16 and returns it to the customer by opening the shutter. Thereafter, when the deposit amount is confirmed by the customer, the automatic teller machine 1 conveys the banknotes stored in the temporary holding unit 20 to the discrimination unit 18 to obtain the discrimination result and the identification result of the serial number. Here, the automatic teller machine 1 conveys and stores the banknotes determined to be storable based on the discrimination result and the identification result of the discrimination unit 18 to each banknote storage 26 according to the denomination. On the other hand, the automatic teller machine 1 is about banknotes determined to be unsuitable for storage, such as banknotes with serial numbers that match a serial number registered in the serial number information list with a certain number of characters or more. Transport to reject box 28.

  On the other hand, at the time of withdrawal transaction, when the withdrawal transaction is selected by the customer via the operation display unit 6 and the withdrawal amount is input by the customer, the number of banknotes for each denomination required according to the requested amount. The banknotes are fed out from each banknote storage 26 according to the number of banknotes for each denomination and conveyed to the discrimination unit 18 to obtain the discrimination result and the identification number identification result. Here, the automatic teller machine 1 conveys the banknote determined to be withdrawable based on the discrimination result and the identification result of the discrimination unit 18 to the depositing / withdrawing unit 16. On the other hand, the automatic teller machine 1 conveys the banknote determined to be unsuitable for withdrawal to the temporary storage unit 20 and temporarily stores it. And when the banknote for request | requirement money amount is integrated | stacked on the deposit or withdrawal part 16, the automatic teller machine 1 will open a shutter. As a result, it becomes possible to receive the banknotes accumulated in the depositing / withdrawing unit 16, and the customer receives the banknotes. Thereafter, the automatic teller machine 1 conveys and stores the banknotes stored in the temporary storage unit 20 to the reject store 28.

[1-3. Serial number registration process]
Next, the specific processing procedure of the serial number registration process by the banknote depositing / withdrawing machine 10 will be described in detail with reference to the flowchart shown in FIG. Here, if the basic function related to the serial number registration process in the banknote depositing and dispensing machine 10 is represented by a functional block diagram, it is as shown in FIG. In FIG. 4, the serial number reading unit 40, the serial number information generation unit 42, and the serial number information registration unit 44 correspond to the discrimination unit 18.

  The serial number reading unit 40 reads an image including a serial number assigned to at least two places (first serial number position P1 and second serial number position P2) of the banknote, and first serial number image data PC1 (not shown). ) And second serial number image data PC2 (not shown). The serial number information generation unit 42 estimates the serial number from the first serial number image data PC1 and the second serial number image data PC2 generated by the serial number reading unit 40, and from the common serial number information IIDC or the individual serial number information IIDS. The serial number information IID is generated. The serial number information generation unit 42 stores in advance a character image used as a serial number character as a reference character image in order to estimate the serial number from the serial number image data. The serial number information registration unit 44 adds and registers the serial number information IID formed by the common serial number information IIDC or the individual serial number information IIDS generated by the serial number information generation unit 42 to the serial number information list LIID.

  The discrimination unit 18 of the banknote depositing / dispensing machine 10 reads and executes the serial number registration program from the storage unit 14 when the inserted banknote is conveyed from the depositing / withdrawing unit 16 to the discrimination unit 18 at the time of deposit transaction. The serial number registration processing procedure RT1 is started, and the process proceeds to step SP1.

  In step SP1, the discrimination unit 18 reads the image at the first serial number position P1 in the banknote to be registered with the serial number by the serial number reading unit 40, generates first serial number image data PC1, and proceeds to step SP2. In step SP2, the identification unit 18 uses the serial number information generation unit 42 to estimate the serial number from the first serial number image data PC1, generates a first serial number identification result, and proceeds to step SP3.

  Specifically, the serial number information generation unit 42 divides the first serial number image data PC1 for each character of the serial number, and for each of the divided characters, among the reference character images registered in advance. For example, the serial number is estimated by selecting characters having a high degree of coincidence as a correlation coefficient. However, when the highest matching score is less than a predetermined threshold (that is, a character with a high matching score is not found) or the difference between the character with the highest matching score and the second highest matching score is less than the predetermined threshold value. (That is, there are a plurality of characters having a high degree of coincidence), the serial number information generation unit 42 determines the character as an unread character and indicates it with “?”.

  In step SP3, the discrimination unit 18 reads the image at the second serial number position P2 in the banknote to be registered with the serial number by the serial number reading unit 40, generates second serial number image data PC2, and proceeds to step SP4. In step SP4, the discrimination unit 18 uses the serial number information generation unit 42 to estimate the serial number from the second serial number image data PC2 in the same manner as in step SP2, and generates a second serial number identification result, and then proceeds to step SP5. Move.

  In the following steps SP5 to SP9, the discrimination unit 18 causes the serial number information generation unit 42 to generate common serial number information IIDC or individual serial number information IIDS as serial number information IID registered in the serial number information list LIID. In step SP5, the discrimination unit 18 determines whether or not there is an unread character in the first serial number identification result by the serial number information generation unit 42.

  If a positive result is obtained here, the discrimination unit 18 proceeds to step SP6. In step SP6, the discrimination unit 18 uses the serial number information generation unit 42 to determine whether or not there is an unread character in the second serial number identification result. If a positive result is obtained here, the discrimination unit 18 proceeds to step SP7. In step SP7, the discrimination unit 18 determines whether or not the character string of the first serial number identification result and the second serial number identification result is the same by the serial number information generation unit 42. If a positive result is obtained here, the discrimination unit 18 proceeds to step SP8. In step SP8, the discrimination unit 18 generates the common serial number information IIDC shown in FIG. 6 by the serial number information generation unit 42, and proceeds to step SP10.

  On the other hand, if a negative result is obtained in step SP5, step SP6 or step SP7, the discrimination unit 18 proceeds to step SP9, and the serial number information generation unit 42 generates the individual serial number information IIDS shown in FIG. Move.

  In step SP10, the discrimination unit 18 uses the serial number information registration unit 44 to display either the common serial number information IIDC generated in step SP8 or the individual serial number information IIDS generated in step SP9 as serial number information IID. 6 is registered in the serial number information list LIID shown in FIG. 6, and the process proceeds to step SP11 to end the serial number registration processing procedure RT1.

  Here, as shown in FIG. 6, the serial number information list LIID is shown in a list in which the serial number information IID for each banknote is aligned by the number of banknotes taken into the banknote depositing and dispensing machine 10. This serial number information IID is configured by individual serial number information IIDS or common serial number information IIDC.

  For example, individual bank number information IIDS is registered for “Bill 1”. The individual bank number information IIDS has “individual” as the registration format RF and “121-3456” as the registered first serial number identification result RIDS1. And “12-13456” as the registered second serial number identification result RIDS2. The registered first serial number identification result RIDS1 is a result of identifying the first serial number ID1 of the first serial number position P1, and the registered second serial number identification result RIDS2 is the second serial number of the second serial number position P2. This is the result of identifying ID2. In this way, the individual serial number information IIDS is the two serial number identification results that are the same as the number of the serial numbers in accordance with the two serial numbers (first serial number ID1 and second serial number ID2) attached to the banknote. As a registered first serial number identification result RIDS1 and a registered second serial number identification result RIDS2.

  On the other hand, the common serial number information IIDC is registered for “Bill 2”, and the common serial number information IIDC has “common” as the registration format RF and “12345678” as the registered common serial number identification result RIDC. Yes. The registered common serial number identification result RIDC is a result of identifying the first serial number ID1 of the first serial number position P1 (that is, the same result as identifying the second serial number ID2 of the second serial number position P2). Thus, the common serial number information IIDC is the first serial number identification result that is smaller than the number of the two serial numbers (first serial number ID1 and second serial number ID2) attached to the bill. The number identification result and the second serial number identification result are collectively stored as a common serial number identification result. As a result, the data number of the common serial number information IIDC is reduced compared to the individual serial number information IIDS.

[1-4. Bill verification process]
Next, the specific processing procedure of the banknote collation process by the banknote depositing / withdrawing machine 10 is demonstrated in detail using the flowchart shown in FIG.8 and FIG.9. Here, the basic functions related to the banknote verification process in the banknote depositing and dispensing machine 10 are represented by a functional block diagram as shown in FIG. In FIG. 7, the serial number reading unit 40, the serial number information generation unit 42, and the banknote verification unit 46 correspond to the discrimination unit 18.

  The serial number reading unit 40 reads an image including serial numbers assigned to at least two places (first serial number position P1 and second serial number position P2) of the banknote, and the first serial number image data PC1 and the second serial number. Number image data PC2 is generated. The serial number information generation unit 42 estimates the serial number from the first serial number image data PC1 and the second serial number image data PC2 generated by the serial number reading unit 40, and estimates the first serial number identification result CID1 (not shown). ) And an estimated second serial number identification result CID2 (not shown). The banknote collation unit 46 includes the serial number identification result of the serial number information IID registered in the serial number information registration unit 44, the estimated first serial number identification result CID1 and the estimated second serial number identification generated by the serial number reading unit 40. The result CID2 is compared and the bill is verified. In order to estimate the serial number from the serial number image data, the banknote verification unit 46 stores in advance a character image used as a serial number character as a reference character image.

  When the bill collation processing is performed, the serial number registration processing described above has already been performed, and the serial number information registration unit 44 is already registered with the serial number information list LIID (FIG. 6). In this bill verification process, for example, a forged ticket is found from a bill inserted at the time of a deposit transaction, or a bill loaded in the bill storage 26 at a cash center outside the automatic teller machine 1 It is performed to determine whether or not the cash automatic transaction apparatus 1 has been withdrawn before being attached.

  The discriminating unit 18 of the banknote depositing / dispensing machine 10 reads and executes the banknote collation program from the storage unit 14 when the inserted banknote is conveyed from the depositing / dispensing unit 16 to the discrimination unit 18 at the time of deposit transaction, for example. The bill verification processing procedure RT2 is started, and the process proceeds to step SP21.

  In step SP21, the discrimination unit 18 reads the image at the first serial number position P1 in the verification target banknote to be verified by the serial number reading unit 40, generates the first serial number image data PC1, and proceeds to step SP22. In step SP22, the discrimination unit 18 estimates the serial number from the first serial number image data PC1 by the serial number information generation unit 42 in the same manner as in step SP2 in the serial number registration processing procedure RT1 (FIG. 5). One serial number identification result CID1 (not shown) is generated, and the process proceeds to step SP23.

  In step SP23, the discrimination unit 18 sequentially searches the serial number information IID in the serial number information list LIID registered in the serial number information registration unit 44 by the bill collation unit 46 as a read comparison target, and proceeds to step SP24. In step SP24, the discrimination unit 18 determines whether or not the serial number information IID to be read and compared is the common serial number information IIDC by the bill verification unit 46. If a positive result is obtained here, the discrimination unit 18 proceeds to step SP25, and the banknote verification unit 46 compares the registered common serial number identification result RIDC in the common serial number information IIDC with the estimated first serial number identification result CID1. Then, the process proceeds to step SP26.

  In step SP <b> 26, the discrimination unit 18 determines whether the registered common serial number identification result RIDC and the estimated first serial number identification result CID <b> 1 are matched by the banknote verification unit 46. Specifically, the banknote verification unit 46 compares the registered common serial number identification result RIDC with the estimated first serial number identification result CID1, and determines whether or not all characters in the character string including unread characters match. To do. If a positive result is obtained here, the discrimination unit 18 moves to step SP29, and the banknote verification unit 46 extracts the common serial number information IIDC including the registered common serial number identification result RIDC from the serial number information list LIID. It adds to the 1st narrowing down serial number information list LIID1 (not shown). On the other hand, if a negative result is obtained in step SP26, the discrimination unit 18 proceeds to step SP30. The first narrowed serial number information list LIID1 is a serial number information list narrowed down from the serial number information list LIID by the estimated first serial number identification result CID1.

  On the other hand, if a negative result is obtained in step SP24, this indicates that the serial number information IID currently being read and compared in the serial number information list LIID is the individual serial number information IIDS. Control goes to step SP27. In step SP27, the discrimination unit 18 compares the registered first serial number identification result RIDS1 in the individual serial number information IIDS and the estimated first serial number identification result CID1 by the bill verification unit 46 in the same manner as in step SP25. The process proceeds to step SP28. Hereinafter, the registered common serial number identification result RIDC and the registered first serial number identification result RIDS1 and the registered second serial number identification result RIDS2 in the individual serial number information IIDS are collectively referred to as a registered serial number identification result.

  In step SP28, the discrimination unit 18 determines whether or not the registered first serial number identification result RIDS1 matches the estimated first serial number identification result CID1 by the bill verification unit 46 in the same manner as in step SP26. If a positive result is obtained here, the discrimination unit 18 proceeds to step SP29, and the banknote verification unit 46 extracts the individual serial number information IIDS including the registered first serial number identification result RIDS1 from the serial number information list LIID. To the first narrowed down serial number information list LIID1. On the other hand, if a negative result is obtained in step SP28, the discrimination unit 18 proceeds to step SP30.

  In step SP30, the discrimination unit 18 determines whether or not the bill collation unit 46 has searched for the last serial number information IID in the serial number information list LIID. If a negative result is obtained here, this means that the serial number information IID that has not yet been collated exists in the serial number information list LIID. At this time, the discrimination unit 18 returns to step SP23, and the next The number information IID is searched.

  On the other hand, if a positive result is obtained in step SP30, the discrimination unit 18 proceeds to step SP31, and the banknote collation unit 46 determines whether or not the first narrowed down serial number information list LIID1 has been created. If a negative result is obtained here, this means that the serial number information IID having the registered serial number identification result that matches the estimated first serial number identification result CID1 was not present in the serial number information list LIID, At this time, the discrimination unit 18 proceeds to step SP42 (FIG. 9).

  On the other hand, if an affirmative result is obtained in step SP31, this means that serial number information IID having a registered serial number identification result that matches the estimated first serial number identification result CID1 exists in the serial number information list LIID. This indicates that the serial number information IID is narrowed down from the serial number information list LIID and the first narrowed serial number information list LIID1 is created. At this time, the discrimination unit 18 proceeds to step SP32.

  In step SP32, the identification unit 18 reads the image at the second serial number position P2 in the banknote to be verified by the serial number reading unit 40 to generate second serial number image data PC2, and proceeds to step SP33. In step SP33, the discrimination unit 18 estimates the serial number from the second serial number image data PC2 by the serial number information generation unit 42 in the same manner as in step SP22, and estimates the second serial number identification result CID2 (not shown). And moves to step SP34.

  In step SP34, the discrimination unit 18 sequentially searches the serial number information IID in the first narrowed serial number information list LIID1 created in the serial number information registration unit 44 by the bill collation unit 46 as a read comparison target, and step SP35. Move on. In step SP35, the discrimination unit 18 determines whether or not the serial number information IID to be read and compared is the common serial number information IIDC by the bill verification unit 46. If an affirmative result is obtained here, the discrimination unit 18 moves to step SP36, and the banknote collation unit 46 steps the registered common serial number identification result RIDC in the common serial number information IIDC and the estimated second serial number identification result CID2. Comparison is made in the same manner as SP25, and the process proceeds to step SP37.

  In step SP37, the discrimination unit 18 determines whether or not the registered common serial number identification result RIDC and the estimated second serial number identification result CID2 coincide with each other by the bill verification unit 46 in the same manner as in step SP26. If a positive result is obtained here, the discrimination unit 18 moves to step SP40, extracts the common serial number information IIDC including the coincident registered common serial number identification result RIDC from the first narrowed serial number information list LIID1, and the second It adds to narrowing down serial number information list LIID2 (not shown). On the other hand, if a negative result is obtained in step SP37, the discrimination unit 18 proceeds to step SP41.

  On the other hand, if a negative result is obtained in step SP35, this indicates that the serial number information IID currently being read and compared in the first narrowed serial number information list LIID1 is the individual serial number information IIDS. The discrimination unit 18 proceeds to step SP38. In step SP38, the discrimination unit 18 compares the registered second serial number identification result RIDS2 in the individual serial number information IIDS and the estimated second serial number identification result CID2 by the bill verification unit 46 in the same manner as in step SP27. The process proceeds to step SP39.

  In step SP39, the discrimination unit 18 determines whether or not the registered second serial number identification result RIDS2 and the estimated second serial number identification result CID2 coincide with each other using the bill verification unit 46 in the same manner as in step SP28. If a positive result is obtained here, the discrimination unit 18 moves to step SP40, extracts the individual serial number information IIDS including the registered second serial number identification result RIDS2 from the first narrowed serial number information list LIID1, 2. Add to the narrowed down serial number information list LIID2. On the other hand, if a negative result is obtained in step SP39, the discrimination unit 18 proceeds to step SP41.

  In step SP41, the discrimination unit 18 determines whether or not the bill collation unit 46 has searched up to the last serial number information IID in the first narrowed serial number information list LIID1. If a negative result is obtained here, this means that the serial number information IID that has not yet been collated exists in the first narrowed serial number information list LIID1, and the discrimination unit 18 returns to step SP34 at this time. The next serial number information IID is searched.

  On the other hand, if an affirmative result is obtained in step SP41, the discrimination unit 18 moves to step SP42, notifies the operator by displaying the banknote collation result on the operation display unit 6, for example, moves to step SP43, and the bill collation processing procedure RT2. Exit. Specifically, when the banknote having the same serial number as the registered serial number identification result is taken in, the discrimination unit 18 displays the fact on the operation display unit 6 by the control unit 12.

[1-5. effect]
In the above configuration, the automatic teller machine 1 determines whether there is an unread character in at least one of the first serial number identification result or the second serial number identification result, or the first serial number identification result and the second serial number identification result. If there is no unread character in the number identification result, but the character string of the first serial number identification result and the second serial number identification result are not the same, the registered first serial number identification result which is a different character string By storing the individual serial number information IIDS having the RIDS1 and the registered second serial number identification result RIDS2 for one banknote, the verification accuracy during the banknote verification process can be maintained.

  On the other hand, the automatic teller machine 1 has no unread characters in the first serial number identification result and the second serial number identification result, and the character strings of the first serial number identification result and the second serial number identification result are the same. In this case, the common serial number information IIDC having one registered common serial number identification result RIDC is stored for one banknote, so that the amount of data to be stored is reduced compared to the individual serial number information IIDS. The memory usage consumed when registering the number information can be saved.

  The serial number information IID in the serial number information list LIID increases the number of registered banknotes as the number of registered banknotes increases. As the number increases, the amount of data becomes enormous. On the other hand, the automatic teller machine 1 has no unread characters in the first serial number identification result and the second serial number identification result, and further a character string of the first serial number identification result and the second serial number identification result. Are the same, it is not necessary to store both the first serial number identification result and the second serial number identification result, and it is sufficient to store either one, so the first serial number identification result In addition, the common serial number information IIDC having the registered common serial number identification result RIDC in which the second serial number identification results are collected is stored.

  Thus, the automatic teller machine 1 can reduce the amount of data by switching the serial number identification result to register according to the identification result of several serial numbers.

  By the way, at the time of banknote verification, the conventional automatic teller machine 1 generates an estimated serial number identification result by using a plurality of serial numbers assigned to a plurality of locations of the banknote as the same serial number, and the banknote is based on the estimated serial number identification result. There was a case to collate. However, in that case, the serial number identification result at the position where it is difficult to read due to the relationship with the surrounding pattern of the part where the serial number is attached, or the serial number identification result that is difficult to read due to contamination etc. affects the collation result. Could be wrong.

  On the other hand, the automatic teller machine 1 compares the registered serial number identification result with both the estimated first serial number identification result CID1 and the estimated second serial number identification result CID2. As described above, the automatic teller machine 1 compares the serial number identification results at the plurality of positions registered in advance by the serial number registration process with the serial number identification results at the respective positions of the banknotes to be verified. You can check well.

  According to the above structure, the automatic teller machine 1 identifies the serial number from the serial number reading part 40 which reads the serial number image which is an image containing the serial number attached | subjected to at least two places of a banknote, and a serial number image. Serial number information generating unit 42 for acquiring serial number identification results, and serial numbers for registering one or a plurality of serial number identification results for one banknote based on the serial number identification results in serial number information generating unit 42 An information registration unit 44 is provided. Thereby, the automatic teller machine 1 reduces the data amount at the time of registering a serial number identification result compared with the case where only one serial number identification result is registered compared with the case where a plurality of serial number identification results are registered. can do.

[2. Other Embodiments]
In the above-described embodiment, the case where the present invention is applied to the banknote in which serial numbers are arranged at two locations, the first serial number position P1 and the second serial number position P2, has been described. The present invention is not limited to this, and the present invention may be applied to various numbers of banknotes having three or more serial numbers.

  When there are three or more serial numbers, at the time of serial number registration processing, there is no unread character in all of the serial numbers allocated a predetermined number, and the serial number identification results of all serial numbers are the same In this case, by storing all the serial number identification results together as common serial number information, the amount of data to be stored can be reduced as compared with the case where the serial number identification results for all serial numbers are stored individually. .

  In addition, when three or more serial numbers are arranged, at the time of bill verification processing, after creating the second narrowed serial number information list, the serial number is estimated from the serial number image data to be compared next. Generate an estimated serial number identification result, compare the estimated serial number identification result with the registered serial number identification result, and create an appropriate narrowed serial number information list according to the number of serial numbers attached to the banknote. It ’s fine.

  In the above-described embodiment, “common” or “individual” is provided as the registration format RF of the serial number information list LIID, and in the case of “common” (in the case of the common serial number information IIDC), the first serial number identification The result and the second serial number identification result are collectively stored as a registered common serial number identification result RIDC. On the other hand, in the case of “individual” (in the case of individual serial number information IIDS), the registration number which is the first serial number identification result is stored. The case where both the first serial number identification result RIDS1 and the registered second serial number identification result RIDS2 as the second serial number identification result are separately registered has been described. The present invention is not limited to this, and a registration format may be provided in which only one of the registered first serial number identification result RIDS1 or the registered second serial number identification result RIDS2 is registered.

  Further, in the above-described embodiment, the case has been described in which the individual serial number information IIDS is stored when there is an unread character in either the first serial number identification result or the second serial number identification result. The present invention is not limited to this. When it is determined that the first serial number identification result and the second serial number identification result are unread characters at the same position in the character string of the serial number, the first serial number identification result and the second serial number identification result The two serial number identification results may be regarded as the same, and the common serial number information IIDC may be stored.

  Further, in the above-described embodiment, the case where unread characters are registered as “?” At the time of serial number registration processing has been described. However, the present invention is not limited to this, and the character having the highest degree of coincidence is second. When the difference from a character with a high matching score is less than a predetermined threshold (that is, there are a plurality of characters with a high matching score and a plurality of candidates such as “1” or “I”), as shown in FIG. Alternatively, “★”, which is a character that is not used for the serial number, may be indicated as a plurality of candidate characters. The automatic teller machine compares the registered serial number identification result with the estimated serial number identification result for all characters including the match of a plurality of candidate characters at the time of bill verification, and determines whether or not the character strings match. The accuracy at the time of bill verification can be improved.

  Further, among the plurality of serial numbers assigned to the banknotes, all serial number identification results not including unread characters or multiple candidate characters are registered (that is, serial number identification results including unread characters or multiple candidate characters are not registered). You may do it.

  Moreover, all the serial number identification results including at least one character other than the unreadable character or the plurality of candidate characters among the plurality of serial numbers attached to the banknote are registered (that is, the serial number of only the unread character or the plurality of candidate characters). The identification result may not be registered.

  In addition, among the plurality of serial numbers assigned to the banknotes, only a predetermined number of serial number identification results are registered from among a plurality of serial number identification results that do not include unread characters or multiple candidate characters (that is, not valid). Even if there are three plural serial number identification results that do not include a reading character or plural candidate characters, for example, only two may be registered).

  Alternatively, a preset number may be registered in order from the serial number identification result with the highest reliability (that is, the serial number identification result with the lower reliability is not registered). Alternatively, all the serial number identification results whose reliability is equal to or higher than a predetermined threshold may be registered (that is, serial number identification results whose reliability is lower than the predetermined threshold are not registered). Here, the reliability is the sum of the matching numbers of each character of the serial number for the number of characters of the serial number, the low number of unread characters, and the like. In addition to the reliability, various other determination criteria may be used.

  Further, in the above-described embodiment, during the serial number registration process, all characters are registered in both the first serial number ID1 and the second serial number ID2, and the first serial number identification result RIDS1 and the registered second serial number identification result The case of registering as RIDS2 has been described. The present invention is not limited to this, and even if characters corresponding to different numbers in the first serial number ID1 and the second serial number ID2 are registered as the registered first serial number identification result RIDS1 and the registered second serial number identification result RIDS2, good.

  Further, in the above-described embodiment, the case where the serial number identification result estimated from the serial number image data is stored has been described. However, the present invention is not limited to this, and serial number image data is stored together with the serial number identification result. May be. In this case, as the individual serial number information IIDS, the first serial number image data PC1 together with the registered first serial number identification result RIDS1 and the second serial number image data PC2 together with the registered second serial number identification result RIDS2 are displayed on the operation display unit 6, respectively. The registered first serial number identification result RIDS1 and the registered second serial number identification result RIDS2 are displayed in the same character while the operator visually observes the first serial number image data PC1 and the second serial number image data PC2. If corrected so as to form a column, the registered first serial number identification result RIDS1 and the registered second serial number identification result RIDS2 may be stored as common serial number information IIDC having a registered common serial number identification result RIDC. good.

  Further, in the above-described embodiment, the case where the serial number identification result estimated from the serial number image data is stored has been described. However, the present invention is not limited to this, and serial number image data is stored instead of the serial number identification result. You may do it.

  Furthermore, in the above-described embodiment, the case where it is determined whether or not there is an unread character in the first serial number identification result and the second serial number identification result in the serial number registration process has been described. Not only, it is determined whether or not there is an unread character or a plurality of candidate characters in the first serial number identification result and the second serial number identification result, or whether any one of the unread character or the plurality of candidate characters is not present. Or may be determined.

  Furthermore, in embodiment mentioned above, in a banknote collation process, it compares a registration serial number identification result with an estimated serial number identification result in all the characters including an unread character, and it is determined whether a character string corresponds. The case of judging was described. The present invention is not limited to this, and it may be determined whether or not the character strings match except when there is an unread character in the registered serial number identification result or the estimated serial number identification result. Further, when there are a plurality of candidate characters in either the registered serial number identification result or the estimated serial number identification result, the other corresponding character of the registered serial number identification result or the estimated serial number identification result is, for example, “1” or When the characters can be a plurality of candidates such as “I”, it may be determined that they match.

  Furthermore, at the time of banknote verification processing, only one of the common serial number information IIDC or the individual serial number information IIDS is extracted from the serial number information list LIID, and the first narrowed serial number information list LIID1 is created. If there are no unread characters and multiple candidate characters in serial number information IIDC or individual serial number information IIDS, banknote verification is performed without creating second narrowed serial number information list LIID2 from first narrowed serial number information list LIID1. The processing procedure RT2 may be terminated. In this case, since it is not necessary to create the second narrowed serial number information list LIID2 from the first narrowed serial number information list LIID1, the processing can be speeded up.

  Further, in the above-described embodiment, when the serial number information IID to be read and compared is the common serial number information IIDC at the time of the banknote verification process, the registered common serial number identification result RIDC and the estimated first serial number identification result CID1 and While comparing the estimated second serial number identification result CID2, if the serial number information IID to be read and compared is the individual serial number information IIDS, the registered first serial number identification result RIDS1 and the estimated first serial number identification result CID1 The case where the registered second serial number identification result RIDS2 is compared with the estimated second serial number identification result CID2 has been described. The present invention is not limited to this. In the individual serial number information IIDS, the registered first serial number identification result RIDS1 is compared with the estimated first serial number identification result CID1, and further, the registered second serial number identification result RIDS2 is estimated. While the two serial number identification results CID2 are compared, in the common serial number information IIDC, the registered common serial number identification result RIDC is not compared with the estimated second serial number identification result CID2. Only the estimated first serial number identification result CID1 may be compared. In this case, since the registered common serial number identification result RIDC and the estimated second serial number identification result CID2 are not compared, the processing can be speeded up.

  Further, at the time of the banknote verification process described above, for example, if there is individual serial number information IIDS in which the registered first serial number identification result RIDS1 is registered but the registered second serial number identification result RIDS2 is not registered, the registration number The comparison between the second serial number identification result RIDS2 and the estimated second serial number identification result CID2 may be skipped and not excluded as a candidate to be extracted into the second narrowed serial number information list LIID2.

  Furthermore, in the above-described embodiment, the case where the present invention is applied when performing both the serial number registration process and the banknote verification process is described. However, only the serial number registration process is performed, and the registered serial number identification result is, for example, The present invention may also be applied to display on the operation display unit 6.
