Description

Paper sheet discrimination apparatus {PAPER SHEET IDENTIFYING APPARATUS}

The present invention relates to a paper sheet discriminating apparatus having a discriminating section for discriminating the authenticity of paper sheets.

Background Art Conventionally, a banknote discrimination apparatus having a sensor for reading the characteristic of a banknote and a discriminating part for discriminating the authenticity of the banknote based on the feature amount of the banknote read by the sensor are known (see Patent Document 1, for example). .

In such a banknote discrimination apparatus, for example, a maximum value and a minimum value are set in advance as a determination value serving as a criterion for authenticity determination, and a range from the maximum value to the minimum value is set as the reference range. And the discrimination | determination part judges that the said banknote as true winding when the characteristic amount of a banknote is contained in a reference range, and discriminates the said banknote as a counterfeit right when the characteristic amount of a banknote is not included in a reference range.

Said reference range is set in consideration of the deviation of the output of a sensor, the deviation of the position at the time of reading a banknote, the secular variation of a banknote, etc. In this case, when the standard range is widened, there is a possibility that the counterfeit right will be misidentified as a true right, resulting in damage to financial institutions or the like. On the other hand, when the reference range is narrowed, there is a possibility that mis-recognition of true right as a counterfeit right increases, and the return rate of true right increases, which may lower user convenience.

Moreover, in general, some of the characteristics of banknotes circulated in the market vary depending on the print shop or the printing timing. And when the banknote which differs in a part of a feature is put into a banknote discrimination apparatus, there exists a possibility that a banknote may be misrecognized as a counterfeit right because a part of a feature differs. In this case, the convenience of the user is lowered by increasing the return rate of the true ticket. Therefore, it is conceivable to widen the reference range so as to discriminate between banknotes of which some of the features are different.

Japanese Patent Application Laid-Open No. 2007-219817

However, as mentioned above, when the reference range is widened, there is a risk that the counterfeit right will be incorrectly judged as a true right, and there is a problem that the discrimination accuracy of the banknote decreases.

This invention solves the subject mentioned above, The objective is providing the paper sheet discriminating apparatus which can suitably determine the authenticity of paper sheets in which a part of a characteristic differs, while suppressing the fall of discrimination precision. It is.

In the paper sheet discriminating apparatus of the present invention, the authenticity of the paper sheet is determined based on the reading unit for reading the feature of the paper sheet containing the reference number and the paper sheet read by the reading unit. And a storage unit for associating and storing a paper number of paper sheets and a unique discrimination value for discriminating the authenticity of paper sheets. The discriminating unit judges whether or not the paper numbers of the paper sheets read by the reading unit are stored in the storage unit, and when it is determined that the paper numbers of the paper sheets are stored in the storage unit, it corresponds to the paper numbers of the paper sheets. The authenticity of the paper sheets is determined by using the unique distinguished values.

In this way, by storing the serial numbers of the paper sheets with different parts of the features and the distinctive values corresponding to the paper sheets in the storage unit, the papers with different parts of the features are distinguished according to the paper sheets. The value can be used to determine the authenticity of the paper sheet. Thereby, because a part of the characteristics of a paper sheet differs, it can suppress that a paper sheet is mistaken as a counterfeit right. In addition, by using the unique discrimination value, it is not necessary to widen the reference range of the common discrimination value, so that the misrecognition of the counterfeit right as the true winding can be suppressed. As a result, it is possible to appropriately determine the authenticity of paper sheets in which some of the features are different while suppressing the decrease in the discrimination accuracy.

In the paper sheet discriminating apparatus, the memory section stores a common discrimination value for discriminating the authenticity of the paper sheet, and the discriminating section stores the common discrimination value when it is determined that the paper number of the paper sheet is not stored in the storage section. It is also possible to determine the authenticity of the paper sheets.

In this case, the common discrimination value is a discrimination value for discriminating the authenticity of the standard sheet paper, and the distinctive discriminating value is a discrimination for discriminating the authenticity of paper sheets having a part of a feature different from the standard sheet paper. It may be a value.

In the paper sheet discriminating apparatus, the storage unit may store the paper number and the type of the paper sheet and the unique discrimination value for discriminating the authenticity of the paper sheet.

In the paper sheet discriminating device, the paper number stored in the storage unit may include a start and end number.

According to the present invention, it is possible to provide a paper sheet discriminating apparatus capable of appropriately determining the authenticity of paper sheets in which some of the features are different while suppressing the decrease in the discrimination accuracy.

EMBODIMENT OF THE INVENTION Hereinafter, one Embodiment of this invention is described, referring drawings. In addition, the following embodiment demonstrates the case where this invention is applied to ATM (Automated Teller Machine) which is an example of a paper sheet discrimination apparatus.

First, with reference to FIGS. 1-4, the structure of ATM 100 which concerns on one Embodiment of this invention is demonstrated.

The ATM 100 is connected to the host computer 200 via the network 150 as shown in FIG. In addition, although only one ATM 100 is shown in FIG. 1 for simplicity, the several ATM 100 is actually connected to the host computer 200 via the network 150. In FIG.

The ATM 100 is installed in a financial institution or the like for the user to conduct a transaction such as depositing a bill. The ATM 100 includes a touch panel 1, a motor 2, a sensor 3, a communication unit 4, a control unit 5, and a storage unit 6, which are buses. It is connected via 100a. In addition, the sensor 3 is an example of the "reading part" of this invention, and the control part 5 is an example of the "discrimination part" of this invention.

The touch panel 1 has a display part and an input part, displays the transaction content, or accepts an instruction from the user. The motor 2 drives the conveyance roller 8 (refer FIG. 2) mentioned later. The sensor 3 has an optical sensor using visible light or ultraviolet light and a magnetic sensor, and reads out characteristics such as image data and magnetic data of a bill. The communication unit 4 is provided for communicating with the host computer 200 via the network 150.

 The control unit 5 includes a CPU, a ROM, and a RAM, and controls the operation of the ATM 100. For example, when the characteristic of a banknote is read by the sensor 3, the control part 5 calculates the characteristic amount of a banknote based on the detection result of the sensor 3.

Here, the feature amount of a banknote is a value used for the determination of the paper type and authenticity of a banknote, and it calculates two or more about one banknote. An example of the feature amount of a banknote is the density value of the predetermined area | region of a banknote. In addition, the feature number of a banknote includes the serial number printed on the banknote. In addition, the operation control by the control part 5 is demonstrated in detail later.

As shown in FIG. 3, the memory | storage part 6 memorize | stores the discrimination value 6a for authenticity determination of a banknote for every characteristic amount of a banknote. This discrimination value is a common discrimination value for discriminating authenticity of standard banknotes widely distributed in the market. The common determination value has a maximum value and a minimum value, for example, and is set in advance on the basis of the frequency distribution of the feature quantities calculated when the standard banknote (true winding) is read by the sensor 3. The storage unit 6 also stores a discrimination value for determining the type of money.

In addition, the storage unit 6 is distinctive for discriminating the authenticity of banknotes having different portions in accordance with differences in printing shops or printing times as compared to standard banknotes widely distributed in the market as shown in FIG. 4. The values are also stored in a database. The distinctive determination value has a maximum value and a minimum value, for example, and is set in advance on the basis of the frequency distribution of the feature quantities calculated by the sensor 3 when a bill (a true winding) in which some of the features are different is read. .

Specifically, in the database 6b, information regarding the paper type of the bill, the billing number (starting number and ending number) of the bill, the feature amount, and the distinctive determination values (minimum value and maximum value) are registered. In addition, the paper type of a banknote and the serial number of a banknote are data for specifying a banknote.

In the example of FIG. 4, when authenticity is performed with respect to the banknote whose gold type is "5000" and the base number is "AB01234", since the said banknote is registered in the database 6b, it is related with "characteristic amount D". When authenticity determination is performed, a unique discrimination value having a minimum value of "0" and a maximum value of "25" is used.

Similarly, when authenticity is performed on the bills with the gold type of "1000" and the serial numbers "CD87654" to "CD88000", the bills are registered in the database 6b. When authenticity determination is performed, a distinctive value with a minimum value of "5" and a maximum value of "45" is used, and when an authenticity determination with respect to "feature amount B" is performed, the minimum value is "150" and the maximum value. This distinction value "230" is used.

Moreover, as shown in FIG. 2, the ATM 100 includes an entry and exit 7, a conveying roller 8, a discriminating unit 9, a temporary holding unit 10, a storage 11, The reject stack 12 is provided.

The entrance / exit 7 is provided in order to exchange bills with the user. The conveyance roller 8 is provided in multiple numbers in order to convey a banknote. The discriminating unit 9 is provided with a sensor 3 (see FIG. 1). The temporary holding part 10 temporarily holds a banknote when exchanging money with a user.

A plurality of banknotes of a particular gold type are stored in the plurality of storages 11, respectively. The banknote 11 (reusable banknote) which can be withdrawn is accommodated in this storage 11. In the reject store 12, reusable banknotes, such as a damage ticket and a counterfeit ticket, are accommodated.

As shown in FIG. 1, the host computer 200 includes a communication unit 201, a storage unit 202, and a control unit 203.

The communication unit 201 is installed to communicate with the ATM 100 via the network 150. The storage unit 202 stores a transaction history and the like in the ATM 100. The controller 203 includes a CPU, a ROM, and a RAM, and controls the operation of the host computer 200.

Next, with reference to FIGS. 1-6, the operation | movement at the time of deposit transaction of the ATM 100 which concerns on one Embodiment of this invention is demonstrated. In addition, each step of the flowchart of FIG. 5 and FIG. 6 is performed by the control part 5 (refer FIG. 1) of ATM100.

First, in the ATM 100, it is determined in step S1 of FIG. 5 whether or not a deposit transaction is selected among various transactions displayed on the touch panel 1 (see FIG. 1). If it is determined that a deposit transaction has not been selected, step S1 is repeatedly performed. In other words, the ATM 100 waits until a deposit transaction is selected. When it is determined that the deposit transaction has been selected, the process proceeds to step S2.

Next, in step S2, it is determined whether or not a banknote has been put into the cash in / out port 7 (refer FIG. 2) within a predetermined period. It is judged based on the detection result of a sensor (not shown) whether this banknote was thrown in or not. If it is determined that banknotes have not been inserted even after a predetermined period has elapsed, the deposit transaction is stopped. If it is determined that the banknote has been put in the predetermined period, the process proceeds to step S3. In the case where a plurality of banknotes are inserted into the entry / exit 7, the following steps S3 to S7 are performed for all the banknotes inserted.

Next, in step S3, by driving the motor 2 (refer FIG. 1), the conveyance roller 8 (refer FIG. 2) rotates, and the banknote injected into the cash-out and receptacle 7 is the discriminating part 9 ( 2).

Next, in step S4, the discrimination process with respect to a banknote is performed. Specifically, in step S21 of FIG. 6, the characteristic of the banknote conveyed is read by the sensor 3 (refer FIG. 1) provided in the discriminating part 9. And the characteristic amount of a banknote is calculated by the control part 5 based on the detection result of the sensor 3.

Next, in step S22, the gold type of a banknote is determined based on the calculated characteristic amount of the banknote. In addition, the determination of the denominations is performed using the denomination determination value stored in the storage unit 6 (see FIG. 1). And in step S23, the billing number of a banknote is determined based on the calculated characteristic amount of the banknote.

Next, in step S24, it is judged whether the said banknote is registered in the database 6b (refer FIG. 4) based on the paper type of a banknote and the note number of a banknote. And when it is determined that a banknote is registered in the database 6b, it transfers to step S25. On the other hand, when it is judged that a banknote is not registered in the database 6b, it transfers to step S26.

In step S25, the authenticity of a banknote is determined using the unique discrimination value registered in the database 6b. For example, in the case of the paper money of "1000" and the note number "CD88000", the distinctive determination value (refer FIG. 4) is registered about "feature amount A" and "feature amount B". In this case, when the value of the calculated characteristic amount with respect to "feature amount A" is within the range of the discrimination value ("5"-"45") registered in the database 6b, in "feature amount A", It is judged to be true. Similarly, when the value of the calculated characteristic amount is within the range of the discriminated value ("150"-"230") registered in the database 6b, the "feature amount B" is true in "feature amount B". Judging. And if it is not registered in the database 6b about "feature amount C", the value of the calculated characteristic amount will be in the range of the common discrimination value 6a ("5"-"10") shown in FIG. In this case, it is judged as true authority in the "feature amount C". Thereafter, the authenticity is determined in the same manner as for the other feature amounts. And the authenticity of a banknote is discriminated | determined by comprehensively judging those results.

In step S26, the authenticity of a banknote is determined using the common discrimination value 6a (refer FIG. 3) stored in the memory | storage part 6. As shown in FIG. For example, when the paper type is "1000" and the bill is "CD78000", the bill is not registered in the database 6b. In this case, when the value of the calculated characteristic amount with respect to the "feature amount A" is within the range of the common discrimination value 6a ("10"-"50"), it is true in "feature amount A". Judging. Thereafter, the authenticity is similarly determined with respect to other feature amounts such as "feature amount B". And the authenticity of a banknote is discriminated | determined by comprehensively judging those results.

Next, in step S5 of FIG. 5, it is determined whether a banknote is a true winding. And when it determines with a banknote being true winding, it transfers a banknote from the discriminating part 9 to the temporary holding part 10 in step S6. On the other hand, when it is judged that a banknote is not a true ticket, in step S7, a banknote is conveyed from the discriminating part 9 to the cash drawer 7. As a result, the banknote which is determined not to be the real ticket is returned to the user.

Next, in step S8, the amount of bills conveyed to the temporary holding part 10 is displayed on the touch panel 1.

Next, in step S9, it is determined whether or not a deposit is instructed. Specifically, a deposit confirmation button is displayed on the touch panel 1, and it is determined whether the deposit confirmation button has been pressed. When it is determined that the deposit is instructed, the process proceeds to step S10. In the case where a plurality of bank notes are held in the temporary holding unit 10, the following steps S10 to S14 are performed for all the bank notes held. On the other hand, when it is judged that money transfer was not instruct | indicated, in step S16, a banknote is conveyed from the temporary holding part 10 to the deposit / exit opening 7. As a result, the bill is returned to the user, and the deposit transaction is stopped.

Next, in step S10, by driving the motor 2, the conveyance roller 8 rotates and a banknote is conveyed from the temporary holding part 10 to the discriminating part 9. And in step S11, the discrimination process with respect to a banknote is performed. In addition, since the discrimination process in step S11 is the same as the discrimination process in step S4, description is abbreviate | omitted.

Next, in step S12, it is judged whether a banknote is true winding. And when it determines with a banknote being true winding, it transfers a banknote from the discriminating part 9 to the storage 11 in step S13. In addition, the storage 11 in which a banknote is conveyed is selected according to the paper type of a banknote. On the other hand, when it is judged that a banknote is not true winding, it transfers a banknote from the discriminating part 9 to the reject store 12 in step S14.

After that, in step S15, the transaction result is transmitted from the communication unit 4 (see FIG. 1) to the host computer 200 (see FIG. 1) via the network 150 (see FIG. 1).

In this embodiment, as mentioned above, the memory | storage part 6 makes the database DB and memorize | stores the unique discrimination value for discriminating the authenticity of banknotes from which a part of a characteristic differs according to a print shop or a printing time difference. have. And when the banknote is registered in the database 6b, the authenticity of the banknote is performed using the distinctive determination value registered in the database 6b. Thereby, because a part of the characteristic of a banknote differs, it can suppress that a banknote is misrecognized as a counterfeit right. In addition, by using the unique discrimination value, it is not necessary to widen the reference range of the common discrimination value, so that the misrecognition of the counterfeit right as the true winding can be suppressed. As a result, authenticity of a banknote in which a part of a characteristic differs can be performed suitably, suppressing the fall of discrimination precision.

In addition, in this embodiment, the memory | storage part 6 registers the discrimination value of all banknotes in the database 6b by storing the common discrimination value 6a for discriminating the authenticity of the standard banknote widely distributed in a market. In comparison with this case, the capacity of the database 6b can be reduced.

In addition, in this embodiment, by specifying a banknote based on the banknote of the banknote and the banknote number of the banknote, when a plurality of banknotes are circulated, even when banknotes with different banknotes having the same banknote are circulated. The bill can be specified.

In addition, in this embodiment, the starting number and ending ending number are contained in the bill number of the banknote of the database 6b. Here, in the database 6b, unique discrimination values for discriminating the authenticity of banknotes differing in some of the features are registered in accordance with the differences in the printing shop and the printing time. Since the bills which differ in some of the features are likely to have consecutive serial numbers, the serial numbers can be registered one by one by storing the unique discrimination value in units of the range from the starting starting number to the ending ending number. In comparison with the case, the capacity of the database 6b can be reduced.

The present invention can employ various embodiments in addition to those described above. For example, in the said embodiment, although the example which applied this invention to the ATM 100 which discriminates a banknote was shown, it is not limited to this, It looked at the paper sheet discriminating apparatus which discriminates other paper sheets, such as securities. You may apply an invention.

In addition, in the said embodiment, although the authenticity determination which applied this invention at the time of a deposit transaction was shown, it is not limited to this, You may make authenticity determination which applied this invention at the time of withdrawal transaction and banknote replenishment. .

In addition, although the said embodiment showed the example which conveys a banknote to the deposit / exit 7 (step S7) when it is determined in step S5 of FIG. 5 that it is not true winding, it does not restrict to this, but to step S5 Therefore, when it is judged that it is not genuine winding, you may collect a banknote by conveying a banknote to the reject store 12. In addition, although the example which conveyed a banknote to the reject store 12 (step S14) was shown when it is determined in step S12 that it is not true ticket, it is not limited to this, It is determined in step S12 that it is not true ticket. In this case, the paper money may be returned to the user by conveying the paper money to the entry / exit 7.

In addition, in the said embodiment, although the maximum value and the minimum value were shown as a determination value, it is not limited to this, A determination value may be one threshold value, and three or more threshold values may be sufficient as it. For example, when the value of the calculated feature amount is between the first threshold value and the second threshold value, it is determined to be true winding and the value of the calculated feature amount is between the third threshold value and the fourth threshold value. In this case, it may be judged as a counterfeit right.

In the above embodiment, the data registered in the database 6b may be transmitted from the host computer 200 via the network 150 so that the database 6b may be updated. In addition, the ATM 100 may update the database 6b based on the transaction history.

In addition, in the said embodiment, although the memory | storage part 6 showed the example which stores the common discrimination value 6a for discriminating the authenticity of the standard banknote widely distribute | circulated in the market, it is not limited to this, but the memory | storage part ( 6) may store the discrimination values of all banknotes in the database 6b without storing the common discrimination value 6a.

In addition, in the said embodiment, although the example which specified the banknote based on the paper type of a banknote and the banknote number of a banknote was shown, it is not limited to this, The banknote based on the banknote of a banknote, the banknote of a banknote, and other characteristic quantities May be specified.

In addition, in the said embodiment, after determining the banknote number of a banknote, the accuracy of the determined banknote number is judged based on the detection result of the sensor 3, and is common when the accuracy is lower than a predetermined threshold value. The authenticity of the banknote may be determined using the discrimination value of. That is, when the banknote number cannot be accurately determined, the authenticity of the banknote may be determined using a common discrimination value.
