Abstract

PROBLEM TO BE SOLVED: To inexpensively improve the judgement of authenticity by judging the authenticity of paper money or the like by the combination of authenticy judgement based on the comparison of all read data of inserted paper money or the like and authenticity judgement based on the comparison of data worked from the read data. SOLUTION: The authenticity of paper money or the like is judged by combining plural judging methods. When three kinds (I to III) of paper money or the like, four kinds (A to D) of inserting methods are prepared, candidates I-A, I-C, II-D and III-C in a judging method 1, I-A and II-C in a judging method 2 and I-A, I-B and III-C in a judging method 3 are respectively judged, the candidate I-A is judged as an authentic object. When two or more candidates are obtained, authenticity is judged by majority, and there is no candidate, the object is judged as a forgery. Since processed data are used, candidates are converted at first by a judgement method capable of judging the characteristic part of the paper money or the like by the small number of comparing data and finally all patterns are compared and judged to shorten processing time.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bill discriminating apparatus, and includes bills and securities (hereinafter referred to as bills, etc.).
This is for improving the identification accuracy of.

[0002]

2. Description of the Related Art In a vending machine, a money changing machine, or the like, it is necessary to determine the type and authenticity of the inserted bill and the like. Means for obtaining information for determining the type and authenticity from a bill or the like include a method of reading a magnetic distribution contained in ink printed by a magnetic sensor, a method of reading a print density and a watermark state by an optical sensor, or both. Is a common method. Since the present invention can be applied to any method without limitation, a description will be given below of a bill discriminating apparatus using an optical sensor as an example.

FIG. 1 is a side sectional view of a bill validator.
FIG. 2 is a top view of the lower part of the bill validator. The bills 1 are conveyed by the conveying means 2 such as a belt, and at the same time, the data relating to the printing pattern and the like of the bills 1 is converted by the optical sensors 3, 4, 5, 6, 7 provided at predetermined positions in the conveying path. Each time the paper is transported by the transport length, it is read, and this is compared with information such as a genuine banknote or other printing pattern (hereinafter, referred to as a standard pattern) stored in a memory in advance to determine the authenticity of the banknote or the like 1 to be identified. It was common to do.

FIG. 3 is a diagram for explaining the above method, in which data read by one optical sensor is graphed. The upper limit value 21 and the lower limit value 22 are set to allow a standard pattern such as genuine bills to have an allowable width (hereinafter, referred to as a standard) set in consideration of individual variations, and the actually read data 23 is plotted. It was done. The authenticity of a bill or the like is determined based on a number out of the standard, a ratio of the number out of the standard, and the like. In FIG. 3, no data deviates from the standard.
Since the above-mentioned bill validator has five optical sensors, five data are collected in the case of one-way insertion of one kind of bill or the like. Since there are four types of insertion directions, 20 types of standard patterns are required to determine the authenticity of one type of bill or the like. If there are three types of banknotes (for example, a 1,000-yen bill, a 5,000-yen bill, and a 10,000-yen bill), there are 60 standard patterns.

FIG. 4 is a block diagram showing a configuration of an embodiment of a conventional judging method. Data read and detected by each of the optical sensors (3 to 7) is sequentially stored in the read detection data storage memory 14. The read detection data storage memory 14 stores the read detection data (1 to 1) of each optical sensor.
n) is stored. The memory 16 stores an upper limit value and a lower limit value in which a standard pattern created based on data read with genuine bills or the like has an allowance. Assuming that there are three types of bills, four types of inserted states, n reading points, and five optical sensors, 3 × 4 × n × 5 × 2 = 1
20 × n data are stored. In addition, the number outside the permissible standard out of n is stored. The comparison / determination unit 15 compares and determines the read data of the read detection data storage memory 14 corresponding to the memory 16 and sums up the result.
Transfer to 7. The counting means counts the determination results (nonstandard numbers). The judging means 18 judges the type and authenticity of the bill by comparing the counting result of the tallying means 17 with the number of non-permissible standards in the memory 16.

[0006]

The printing variation of banknotes and the like varies within the printing lot, but also varies greatly between printing lots. Furthermore, the variation between new and used ones becomes even greater, and unless the standard is expanded, The number of erroneous determinations of genuine banknotes and the like as counterfeit is increased, and the number of erroneous determinations of determining counterfeit as genuine banknotes is increased when the standard is expanded. In any case, there is a problem in the reliability of the bill validator.

In addition, although data is read for each predetermined transport length, there is a drawback that the variation in the reading time direction becomes large due to the expansion and contraction of paper money and the variation in transport, and the standard must be expanded. As a result of comparison with the standard pattern, it is not expected that all will fall within the standard,
Although a judgment method in which an out-of-specification number is allowed to have an allowance has been adopted, this has also brought a possibility of judging a counterfeit as a genuine bill or the like. Furthermore, it is difficult to grasp a characteristic portion of a banknote or the like only by comparing the patterns, and in particular, a synthetic banknote or the like obtained by attaching a forged part of a banknote or the like cannot be accurately determined.

If the number of optical sensors is increased, the accuracy of determination can be increased. However, even if the number of optical sensors is five, comparison with 60 standard patterns is required for authenticating three types of bills. Must be performed, and the comparison processing capability of the bill validator must be increased, so that the bill validator has become expensive. If the processing capacity is low, there is a problem that it takes too much time to determine the authenticity. An object of the present invention is to provide an inexpensive banknote recognizing machine which solves these drawbacks, improves the accuracy of authenticity judgment, and is inexpensive.

[0009]

A bill or the like is inserted, and an optical or magnetic pattern of the bill or the like is read and stored by a plurality of optical sensors or magnetic sensors, and the stored read data and the stored data are stored in the storage means in advance. In an identification device that determines the authenticity of a bill or the like by comparing it with standard pattern data such as a bill, the authenticity is determined by comparing all data of the read data of the inserted bill or the like and / or the authenticity by comparing data obtained by processing the read data. The authenticity of a bill or the like is determined in combination with the determination.

[0010] An identification device for judging the authenticity of a plurality of types of bills, etc., wherein a bill or the like is inserted, and an optical or magnetic pattern of the bill is read and stored by a plurality of optical sensors or magnetic sensors, and the stored reading is performed. In an identification device for determining the authenticity of a bill or the like by comparing the data with standard pattern data such as a bill previously stored in a storage means, an authenticity determination by comparing all data of the read data of the inserted bill or the like and / or It has means to judge the authenticity of bills etc. by a combination of authenticity judgment by comparing read data and processed data, and narrows down the type and insertion direction of bills etc. by comparing all data and / or authenticity judgment by comparing processed data. Then, the type and authenticity of the bill and the like are determined based on the coincidence of the respective authenticity determinations.

An identification device for judging the authenticity of a plurality of types of bills or the like, wherein a bill or the like is inserted, an optical or magnetic pattern of the bill is read and stored by a plurality of optical sensors or magnetic sensors, and the stored reading is performed.

It narrows down to the type of bills and the insertion direction and judges authenticity.

[0012]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The length of a bill or the like is 160 mm. If the length at which the tip of a bill or the like taken into the bill validator reaches the optical sensor and data is read for each transport treatment length is 0.5 mm, 320 points of data will be read. The allowable nonstandard number is set to 32 points in comparison of all points. In this case, the allowable non-standard ratio is 10
Since it is%, it is preferable to set not the permissible standard number but the permissible non-standard ratio in consideration of the expansion and contraction of paper money and the variation in conveyance. The problem of authenticity determination using only the allowable nonstandard number and the allowable nonstandard ratio is as described above.

Judgment method 1 by data processing Combination data of data obtained by a setting rule from a plurality of fixed zones set in advance in a part of a standard pattern is stored as standard data, and data read from a bill or the like is stored in the same manner. And the combination data is obtained, and compared with the standard data, the type of the bill and the insertion direction are determined based on the number of matched pieces of the combination data.

FIG. 5 is a block diagram for explaining the first determination method, and FIG. 6 is a diagram showing a graph of read detection data and a fixed zone for explaining the first determination method. In FIG. 6, point A is a point in time when a bill or the like reaches the optical sensor, and point B is a point in time when the bill or the like has passed. A plurality of fixed zones are provided in the initial data portion of the read detection data. Hereinafter, a method of determining the type and insertion direction of a bill or the like based on a combination of data from a plurality of optical sensors will be described.

An embodiment of the present invention will be described using an example in which read detection data of four to seven optical sensors among the five optical sensors is used. Data of 1 to n is stored as a standard pattern, where n is 320. Data 1 to 1
During 00, a plurality of fixed zones are set in advance. Assume that there are three fixed zones. Although the position and width of the fixed zone are determined by experiments, the number of data is assumed to be 10 for all three fixed zones. Various rules for setting data obtained in the fixed zone are conceivable, and any of an average value, a maximum value, a minimum value, a difference between the maximum value and the minimum value, and the like of the data in the fixed zone may be used. A fixed zone in which the type of bill and the insertion direction can be easily determined according to the data setting rule to be used may be set. Therefore, an example in which the difference between the maximum value and the minimum value is used as data will be described below.

Fixed zones 1, 2, 3 common to each optical sensor
Set. The difference between the maximum value and the minimum value of the data in the fixed zone is obtained based on the standard pattern, and the output from the optical sensor is corrected. With the reference value as 100, the 100% of the difference is obtained, encoded for each 100% rank, and stored in the memory 50. For example, the data of the four optical sensors in the fixed zone 1 in the insertion direction A of the bill I are 30%, 40%, 82%, respectively.
%, 16%. The ranking to encode is 0% to 2
5%, 25% to 50%, 50 to 75%, 75% to 100
% And four ranks, each having a sign of 00, 01, 10, and 11. The four data are coded by rank, and the four codes are combined to form 0101-1100. This is expressed in hexadecimal notation, and as 5C, I-A-
It is stored in zone 1 (the rank of encoding is appropriately set by data obtained from the fixed zone). In consideration of variations in read detection data due to variations in transport of bills and the like in the identification device, all data having a possibility in the IA-zone 1 is stored. It is sufficient to set a fixed zone through which data can be obtained as stable as possible by experiments. The memory 50 stores combination data of three denominations and four inserted states (A, B, C, and D) and three fixed zones.

The data stored in the read detection data storage memory 14 is calculated for each set fixed zone, the combination data is obtained, and the calculation result is stored in the memory 51. The memory 50 and the memory 51
And comparing the data in the memory 5
Store it in 2. Data in fixed zone 1 is light sensor 4

01 and C in the combination 1100 of the optical sensors 6 and 7, and as a result the combination data in the fixed zone 1 is 5C, IA and III-B are candidates as data from the data in the fixed zone 1 in the memory 50. can give. Next, if the data in the fixed zone 2 is 00 for the optical sensor 4, 11 for the optical sensor 5, 11 for the optical sensor 6, and 00 for the optical sensor 7,
The combination 0011 of the optical sensors 4 and 5 is 3 and the combination 1100 of the optical sensors 6 and 7 is C. As a result, the combination data in the fixed zone 2 is 3C. Is a candidate. Next, if the data in the fixed zone 3 is 00 for the optical sensor 4, 11 for the optical sensor 5, 01 for the optical sensor 6, and 00 for the optical sensor 7, the combination 0 of the optical sensors 4 and 5 is 0.
011: 3; Photosensors 6 and 7 combination: 0100: 4
As a result, the data in the fixed zone 3 becomes 34.
Is a candidate.

The direction of insertion of the denomination of IA, in which the inserted bill or the like rises as a candidate three times in three zones, is determined. The criterion for determining the denomination and the insertion direction is to determine whether all zones match, whether the number of candidates is large, whether the number of m zones is n or more, or the number of fixed zones to be set and the target. What is necessary is just to determine by data, such as an identification bill, the position of an optical sensor, the number of optical sensors combined, etc.

Judgment method 2 by data processing An area 1 for obtaining a reference value of a standard pattern such as a genuine bill read and detected by an optical sensor is set, and a reference value is set from the pattern in the area 1. A plurality of characteristic areas (area 2 to area n) are set, a maximum value or a minimum value (referred to as an extremum) of each area is obtained, a difference between the reference value and the extremum is calculated and stored as a standard value. , At least means for reading a pattern such as a bill to be identified by an optical sensor, means for setting a reference value of read data in the same area as the area 1, and a plurality of means set in advance to be the same as the standard pattern. Calculating means for calculating the extreme value of the area of the area, means for calculating the difference between the reference value of the read data and the extreme value of the read data, and the standard value of the corresponding standard pattern in the memory , A counting means for counting the comparison result, and a determination means for determining whether or not the counting result satisfies the determination criterion, to determine the type and direction of the bill or the like.

FIG. 7 is a block diagram for explaining the judgment method 2, and FIG. 8 is a diagram in which areas are set in a graph of read detection data for explaining the judgment method 1. 3 ~
7 is the above-mentioned optical sensor. 14 is a memory for sequentially storing the read detection data of each optical sensor, and 1 to n respectively.
Can be stored up to Numeral 70 denotes an operation and storage means, which sequentially calculates the maximum value or the minimum value of the preset area when the data is stored in the read detection data storage memory 14 (the maximum value or the minimum value is also set in advance). This is means for calculating and storing a difference from a reference value set by the read detection data, and can store a to m.
In area 1, a reference value is set and stored from within area 1. The memory 71 stores the types of bills (three in this embodiment), the insertable directions (four directions), and the number of optical sensors (five in this embodiment), that is, 3 × 4 × 5 = 60 standard patterns in advance. The difference between the reference value and the maximum value or the minimum value of each of the set areas (am) is calculated, and the allowable maximum value, the allowable minimum value (that is, the standard) having the allowable width, and the allowable nonstandard number are stored. Is what is being done. Numeral 72 denotes a comparison / determination means I, which compares the corresponding data in the calculation / storage means 70 and the memory 71, determines whether the data is within the standard or not, and transfers the result to the determination result totaling means 73. The determination result totaling unit 73 is a unit for totalizing the determination results of the above-described 60 patterns, and counts out-of-specification numbers. When the comparison and determination of all data is completed, the comparison and determination means II74 compares the allowable out-of-specification number in the memory 71 with the corresponding out-of-specification number in the determination result totaling means 73 to determine the type and direction of the bill and the like. Although the description has been given of the non-standard number, it is needless to say that the determination may be performed on the in-standard number.

In FIG. 8, the area in which the reference value is set is area 1, and area 1 is the number of the read data. 10
-No. There are 25 sections. If the maximum value of area 1 is set as the reference value, the calculation and storage means
No. of the read data in the read detection data storage memory. 10-No. 25, and the maximum value is selected and stored in area 1. Area a is the read data No.
40-No. If the section is set to 58 and the difference between the reference value and the minimum value is set to be used in the area a, the calculation and storage means determines the read data No. in the read detection data storage memory. 40-No. The minimum value is selected by comparing 58 and the difference from the reference value stored in area 1 is calculated and stored in area a. Next, area b is read data No. 90-No. If the section is set to 110 and the area b is set to use the difference between the reference value and the maximum value, the calculation and storage means determines the No. of the read data in the read detection data storage memory. 90-No. The maximum value is selected by comparing 110 and the difference from the reference value stored in area 1 is calculated and stored in area b. Calculate and store up to m sequentially. 5
Mx because reading and detecting using two optical sensors
5 is calculated and stored. It is not necessary to set m areas in the read detection data of the all-optical sensor, and the number of areas that can prevent erroneous determination is sufficient.

The memory 71 reads a plurality of genuine bills and the like and calculates an average value to create 60 standard patterns.
Data of each area is created in the same manner as described above, and the upper limit and the lower limit having an allowable width are stored. If the extremum in the area is set so that the extremum in the area is at the center of the area when setting the area, even if the extremum position shifts due to the variation, the variation of 1/2 of the area width is absorbed, and erroneous determination can be prevented. The center or one side may be determined based on standard pattern data such as bills.

The determination method will be described in detail with reference to the data of the optical sensor 4. The calculation data of the area stored in the calculation and storage unit 70 is sequentially compared and determined by the comparison determination unit 72 with the data for the optical sensor 4 in the memory 71. First, the operation data of the area a stored in the operation and storage means 70 is compared with the data IA-4-a-up and down of the memory 71, and the judgment result is sent to the judgment result totaling means 73. If the determination result is out of the standard, the I-A
One is added to -4. It is not added if it is within the standard.
Next, IB-4-a-up and down is compared. Sequentially, IC
-4-a-up and down, ID-4-a-up and down, II-B-4-
a-up and down ... III-C-4-a-up and down, III-D-4-
a-up and down is determined, and the determination of the area a is completed.
Similarly, the data of the area b and the data of the area c are sequentially compared and determined.

The comparison / judgment means II74 makes a judgment by associating the 60 summation result of the judgment result summation means with the allowable number of 60 set in the memory 71, and judges the kind and direction of the bill and the like. If the setting of the reference value, the setting of the area, and the like are appropriately set, the number of allowable out-of-specifications can be reduced.

Judgment method 3 by data processing A means for reading a pattern such as a bill by an optical sensor, and comparing the data obtained by the reading means with a certain level, the number of data above the level and below the level or one of the data The type and direction of a bill or the like are determined from the means for calculating the number and the number equal to or more than the level and the number equal to or less than the level.

FIG. 9 is a block diagram for explaining the judgment method 3. 91 is a memory, 92 is a judgment result totaling means,
Reference numeral 14 denotes a memory for storing read detection data, and reference numeral 93 denotes comparison upper / lower determination means. The memory 91 sets and stores a certain fixed level according to the type of bill and the like and the insertion state. The number of storages is the number of optical sensors from all directions in which bills and the like can be inserted times the set number of fixed levels. The determination result totalizing means 92 totalizes the results of the comparison upper and lower determining means 93 described later. The comparison upper / lower determination means 93 includes the optical sensors 3 and 4 stored in the read detection data storage memory 14.
The output values of 5, 6, and 7 are sequentially compared with a certain level in the memory 91.
Output to 2.

Hereinafter, a method of comparing the detection data of each optical sensor with a certain level stored in the memory will be specifically described. FIG.
0 and FIG. 11 are graphs of read detection data for explaining the determination method 3. Line 101 of FIG. 10 and FIG.
Lines 111 and 112 are reference levels for comparison which are set in advance and stored in the memory. In FIG. 10, one level is set, and in FIG. 4, two levels are set. The vertical axis is the detection level, and the horizontal axis is the time axis. This fixed level may determine the level at which features such as banknotes appear. All may be performed at the same level, or may be prepared for each type and direction of bills and the like. Point A in the figure is a point at which a bill or the like reaches the optical sensor, and point B in the figure is a point at which the bill or the like passes through the optical sensor. A space between AB is a reading detection pattern obtained by the optical sensor by a pattern such as printing of a bill or the like.

The data read by the photosensor groups 3 to 7 are stored in the read detection data storage unit 1 to 1 to n in the reading order, respectively. The memory 91 stores three types of bills and the like.
Types (I, II, III), 4 types of insertion direction (A, B, C,
D) Two levels (upper and lower), number of judgment criteria (upper and lower)
Is set.

The optical sensor 3 will be described. When the read detection data from the optical sensor 3 is stored in the read detection data storage memory 14, the successive comparison upper and lower determination means 9
3 is compared with the data in the memory 91. First, the stored data 1 is compared with the data IA-4- on the data stored in the memory 91 to determine whether the data is up or down. If the judgment result is “up”, the IA-4-
Up-Up 1 is counted. If the judgment result is below,
IA-4-1 is counted up-down. Next, the data is compared with the data IA-4-lower in the memory 91 to determine whether the data is up or down. If the determination result is above, the determination result totaling means 92
1 is counted on the IA-4-bottom-top of the table. If the determination result is lower, 1 is counted down as IA-4-lower-lower. The data is compared with the data in the memory 91 one after another, and III-D-
When the process is completed to the bottom, the stored data 2 is next to the data IA-4-top, IA-4-bottom, etc. of the data in the memory 91.
The comparison is performed in the order of III-D-4-down, and the determination results are totaled by the determination result means 92. Similarly, the stored data is compared and judged up to the n-th number, and the judgment reference number of the memory 91 is compared with the corresponding summation result of the judgment result summation means 92, and it is judged whether or not it is applicable. For example, IA-4 of the memory 91
The number of judgment criteria set in the upper part is 80, and the total result in the IA-4 of the judgment result totaling means 92 is 82
If not, it is determined that it does not apply. In this way, the type and direction are determined. If the allowable width is set to ± 5%, it is determined to be applicable.

As a criterion, for example,
IA-4-upper-determined criterion number is 80
In the case where the total result of IA-4-up-up of the determination result totaling means 92 is 82, it is determined that it does not correspond. If the allowable width is set to ± 5%, it is determined to be applicable. In the present embodiment, three types of banknotes (I, II, III) ×
Insertion direction 4 types (A, B, C, D) x 2 levels (upper, lower) x number of reference standards (up, lower) x number of optical sensors 5 =
A determination result of 240 is obtained. Since the total number of upper and lower judgment results of a certain level is the same, the same judgment can be made only by the upper number or the lower number, so the actual judgment result is 120, whereby the type and direction of the bill etc. Is determined. If all of the IA results apply, it is determined to be IA. However, if two of the IA determination results 20 do not apply, it is possible to determine whether the result is acceptable within the allowable range by setting the determination criteria. Is the same as the aforementioned allowable width.
This is because, as pointed out in the problem, the state of the bills and the like is not the same due to many factors.

Another criterion will be described. In the above-described determination method, the determination is made based on the number of the upper and lower levels, but a method of determining based on the ratio of the upper and lower levels can be considered. In FIG. 11, the upper / lower ratio of the level 111 is a = up / down, and the upper / lower ratio of the level 112 is b = up / down. Reference values of the respective ratios are set and stored in the memory, and the determination result is obtained. This is a method of making a comparison with the result of the accumulation means. In the above-described determination based on the upper and lower numbers, the number of the read detection data is set as n. However, the number of data may not be n due to the expansion and contraction of bills and the variation in the transport amount of the transport unit. In this case, an erroneous determination occurs in the determination based on the number, but the erroneous determination can be prevented by setting the upper and lower ratios.

For the setting of the fixed level, it is desirable to set an appropriate level as a reference for judging a bill or the like. This is because the determination accuracy can be improved if a level at which a characteristic number of upper and lower data is set on a line on which a bill or the like is read by the optical sensor can be set. This is set based on the experimental data depending on the arrangement structure of the optical sensor of the identification device and the insertion state of bills and the like. In the example, one or two levels are used, but the determination accuracy can be improved by increasing the number of levels as necessary.

Other Judgment Methods Judgment methods based on data processing include, as a whole, a cumulative value and an average value of data;
A method of comparing the width, the thickness, the characteristic data, the characteristic data, and the pattern of the unique portion can be considered.

In the present invention, the authenticity of a bill or the like is determined by combining a plurality of the above-described determination methods. For example, in judgment method 1, I
-A, IC, II-D, III-C,
If A, II-C, and IA, IB, and III-C are determined by the determination method 3, it is determined as IA. If there are two or more candidates, it is determined by majority vote, and if there is no candidate, it is determined to be counterfeit.

Even in the case of using processed data, candidates are first narrowed down in a characteristic part such as a banknote by a judgment method in which the number of comparison data is small and judgment can be performed by comparing all patterns at the end. Is short. If two judgments are used, most of them can be narrowed down to one. However, the judgment accuracy can be further improved by comparing with a standard pattern as final confirmation.

[0036]

As described above, the judgment is made by combining a plurality of judgment methods, so that the judgment accuracy is improved.

Since the determination can be made by combining the characteristic portion and the whole, the determination accuracy is improved even for a synthesized bill or the like.

Since the narrowing down is performed by a combination of the judging methods, it is not necessary to determine one bill or the like by one judging method, and the degree of freedom in constructing the judging method is increased.

By sequentially narrowing down by the determination method having a high processing speed, the determination processing time is not wasted and the processing time can be reduced.
