FIG. 1 shows a medium processing device 23 according to this embodiment.
2 is a block diagram schematically showing the configuration of FIG. The output of the bill length check sensor 25 is sent to the bill length detection unit 51, and the length of the bill P is detected by measuring the light shielding time due to passage of the bill P, and it is determined whether the bill length is normal or not. To be done. The output of the magnetic head 26 is sent to the magnetic pattern processing unit 52. The magnetic pattern processing unit 52 converts the magnetic pattern of the banknote P obtained by the magnetic head 26 into the reference pattern dictionary 53.
Authenticity determination is performed by matching with the magnetic pattern (reference pattern) of the genuine bill inside.

The output of the image reading sensor 27 is sent to the image pattern processing section 54. The image pattern processing unit 54
By comparing the print pattern of the banknote P obtained by the image reading sensor 27 with the print pattern (reference pattern) of the true note in the reference pattern dictionary 55, the authenticity determination and the denomination determination are performed. At the same time, the print pattern portion of the bill number (reference numeral N in FIG. 1) is extracted from the print pattern of the bill P and sent to the character recognition unit 56.

The character recognition unit 56 recognizes the ticket number by detecting and cutting out the character from the print pattern portion of the inputted ticket number, collating it with the dictionary 57, and storing the ticket number in the ticket number storage unit 58. To do. The ticket number storage unit 58 has an area for storing a predetermined number of ticket numbers, and the character recognition unit 56.
Each time a ticket number is input, the ticket number is sequentially stored. When the storage area becomes full, the oldest ticket number is erased and new ticket numbers are sequentially stored. That is, the ticket number storage unit 58 is configured to cyclically store a predetermined number of ticket numbers.

Further, the ticket number storage unit 58 has a registration area in which a predetermined number of ticket numbers can be registered, and an arbitrary ticket number can be registered in advance by a ticket number input unit 59 such as a keyboard. Has become.

The ticket number recognized by the character recognition section 56 is sent to the ticket number determination section 60. Ticket number determination unit 60
Sequentially compares the ticket number from the character recognition unit 56 with each ticket number of the banknotes P processed in the ticket number storage unit 58 in the past, and when a matched ticket number is found, the banknote P is a duplicate ticket or a counterfeit. It is determined that the ticket is a fake ticket.

The bill length detector 51 and the magnetic pattern processor 5
2, image pattern processing unit 54, and ticket number determination unit 6
Each determination result of 0 is sent to the overall determination unit 61. The comprehensive determination unit 61 outputs a final determination result that the ticket is a valid ticket only when each determination result is a genuine ticket. That is, the final determination result indicating that the bill is valid is output only when the bill length, the magnetic pattern, the image pattern, and the bill number are all determined to be genuine.

Next, the operation of the medium processing device 23 having such a configuration will be described with reference to the flowchart shown in FIG. First, the bill length detection unit 51 checks the bill length of the bill P. That is, the ticket length check sensor 2
The output of 5 counts (measures) the light-shielding time due to the passage of the banknote P, thereby detecting the length of the banknote P and determining whether or not the banknote length is normal.

In the bill length check, if the bill length is normal, then the magnetic pattern processing unit 52 performs a magnetic pattern collation check. That is, the authenticity determination is performed by matching the magnetic pattern from the magnetic head 26 with the magnetic pattern of the genuine bill registered in the reference pattern dictionary 53 in advance.

When a match is obtained in the magnetic pattern matching, the image pattern processing unit 54 next checks the print pattern matching. That is, the authenticity determination is performed by matching the print pattern from the image reading head 27 with the print pattern of the genuine bill registered in the reference pattern dictionary 55 in advance.

At the same time, the image pattern processing unit 54 extracts the print pattern portion of the ticket number from the print pattern of the banknote P and sends it to the character recognition unit 56. Character recognition unit 56
Detects a character from the print pattern portion of the input ticket number, cuts it out, recognizes the ticket number by collating it with the dictionary 57, and stores the ticket number in the ticket number storage unit 58.

If a match is obtained in the image pattern matching, then the ticket number determination unit 60 performs the ticket number matching. That is, the ticket numbers from the character recognition unit 56 are sequentially compared with the ticket numbers (all the ticket numbers already stored in the ticket number storage unit 58) of the previously processed banknotes P in the ticket number storage unit 58, and they match. If you find the ticket number you made,
The banknote P is determined to be a counterfeit note such as a duplicate note or a counterfeit note.

In this case, as described above, the ticket number storage unit 5 previously stores an arbitrary ticket number by the ticket number input unit 59.
You can also register to 8. Then, the comprehensive judgment unit 61
Indicates that the ticket length is normal in the ticket length check, a match is obtained in the magnetic pattern matching, a match is obtained in the image pattern matching, and a match is obtained in the ticket number matching. Only when there is no ticket, the final judgment result that the ticket is valid is output, the ticket length is abnormal in the ticket length check, no match is found in the magnetic pattern matching, or a match is found in the image pattern matching. If it is not obtained or if a match is obtained in the matching of the ticket numbers, the final determination result that the ticket is invalid is output.

That is, only when all the processing of the bill length, the magnetic pattern, the image pattern, and the bill number is judged as a genuine bill, the final judgment result that the bill is valid is outputted, and the bill length and the magnetic pattern are outputted. If at least one of the image pattern processing and the ticket number processing is determined to be a false ticket, the final determination result that the ticket is invalid is output.

As described above, when a bill is taken in by a ticket vending machine or the like, the authenticity is determined by simultaneously reading the bill number peculiar to the bill printed on the bill. That is, the ticket number read from the bill at the time of the current transaction is
A counterfeit ticket (manufactured by the same block) when it matches the ticket number of a banknote processed in the past (within one transaction unit, past transaction) (that is, when a predetermined relationship is established between both ticket numbers) Forged ticket). In addition, by registering a specific ticket number from the ticket number input unit in advance (for example, if a counterfeit ticket is discovered and the ticket number is open to the public, register the ticket number), the same as that. From the beginning, it is determined that the bill with the bill number is a counterfeit bill.
This makes it possible to identify a counterfeit note, which has been difficult in the past, with high accuracy.

Further, in the above-described embodiment, the genuineness / counterfeit discrimination of banknotes is divided into the block length check determination, the magnetic pattern determination, the image pattern determination, and the ticket number determination in blocks, and the authenticity determination is performed in this order. If all are judged to be genuine, it is judged to be valid. At this time, if it is determined that the bill is a counterfeit bill in the first determination (bill length check determination, magnetic pattern determination, etc.), the processing can be ended without performing the subsequent determination, so that the processing speed can be improved.

Further, when a counterfeit note is discovered and an attempt is made to improve the judgment method by adjustment, in the conventional magnetic pattern judgment, for example, delicate adjustment is required, and the adjustment also affects the judgment rate of the true note. However, in the method of the present embodiment, it is only necessary to register the fake ticket number, and it does not affect the others.

In the above-mentioned embodiment, the case where the authenticity of a bill is determined has been described, but the present invention is not limited to this. For example, the authenticity of other securities such as a check is determined. The same can be applied to the case.

[0047]

As described above in detail, according to the present invention, it is possible to provide a medium processing device capable of accurately identifying an invalid note, which has been difficult in the prior art, in the authenticity determination of a bill, for example. .
