Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a banknote inspecting apparatus for inspecting a deposited or dispensed banknote in a banknote handling apparatus such as an automatic teller machine (ATM) and a correction method for the banknote inspecting apparatus.

[0002]

2. Description of the Related Art In a banknote handling apparatus such as an automatic teller machine (ATM), a banknote checking device is mounted to check banknotes to be paid in or out. The banknote inspection device is based on the output of various built-in sensors,
The denomination and the fitness are determined. These sensor outputs are subjected to output adjustment and calibration at the time of assembling adjustment of the banknote inspection device.
Various test tickets (reference tickets) are used for adjustment and calibration, and various test tickets are also used for confirmation after adjustment.

A test ticket (reference ticket) provides a reference for a physical quantity detected by each sensor, and is usually prepared for each sensor to be corrected. For example, a test ticket for thickness detection includes a reference ticket having a thickness of, for example, 100 μm. For magnetic detection, there is a test ticket printed on paper with a fixed magnetic density and partially with magnetic ink.

[0004] The following is a description of bill thickness detection. In the thickness detection, detection of overlapped feeding of bills, abnormal thickness, and tape sticking is performed. In the adjustment of the thickness detection, first, a note (test ticket) having a reference thickness is put into a bill validator, and the output of the thickness detection sensor is hard-adjusted to a reference voltage corresponding to the reference thickness by a volume. Thereafter, a predetermined number of tickets having the reference thickness are again inserted, and the obtained output, for example, an average value is corrected in a software manner as the reference thickness. The thickness of the bill can be detected at the detection level of the bill inspection device adjusted in this manner.

However, in this method, since the calibration is performed using the thickness of the reference medium (test ticket), the accuracy of the calibration depends on the accuracy of the thickness of the reference medium. In general, since the material of the reference medium is a sheet of paper or plastic, there is a variation in thickness in manufacturing. For this reason, as described above, a large number of reference media are put in and an average value is used.

In this case, when the average value is used, the influence of thickness variation is reduced, but if the reference medium is too thick or too thin and deviates from the reference value, the accuracy of calibration is greatly affected. In addition, in the method based on this correction, it is preferable that the number of reference media to be input is large, but this also causes a problem in management and use amount of the reference media.

[0007] It is also conceivable to increase the accuracy of the thickness of the reference medium, but this requires an economically high cost. Further, even when the reference medium is worn out and thinned while being used, or becomes thick due to wrinkles or moisture absorption, the accuracy of the calibration is affected.

[0008]

As described above, in the banknote inspection device, the detection level must be adjusted using a large number of reference media (test tickets), and the reference media may be too thick or thin. If it deviates from the reference value, it will greatly affect the accuracy of calibration, and it will be economically expensive to increase the accuracy of the thickness of the reference medium, and it will wear out and become thinner during use, wrinkles and moisture absorption However, there is a problem that even when the thickness becomes thicker, the accuracy of the calibration is affected and a highly accurate calibration cannot be performed.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a bill validator and a method of correcting the bill validator which can reduce the amount of a reference medium used for bills and perform highly accurate calibration.

[0020]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a schematic configuration of a banknote inspection device according to the present invention. That is, the banknote inspection device 1 is installed on a banknote transport path of a banknote processing device (not shown), and the transport path 2 inside the banknote inspection device 1 is used.
Forms a part of the transport path of the bill processing apparatus.

The banknote inspection device 1 is provided with various sensors as detection means, and performs preprocessing such as amplification, correction, and A / D conversion of the sensor output. The data pre-processed by the banknote inspection device 1 is processed by a control board (not shown) mounted on the banknote processing device main body, and it is determined whether the banknote is authentic, denomination, damage, damage or overlap of banknotes, and skew. The information is notified to the bill processing device.

Banknotes enter the inspection conveyance path entrance 2a, are conveyed while being detected by each sensor, and are transferred to the banknote processing device from the exit 2b. In the transport path 2, the driven rollers 3, 3, 4, 5 and the rollers 6, 6, 7,
8 to transport the banknote. Drive rollers 3,3,
Reference numerals 4 and 5 are rotated together by a motor (not shown) that drives the transport path of the banknote handling machine.

An LED array 9 as a light emitting source, a selfoc lens 10 as a light receiving unit, and a transmission sensor 11 detect the shape of a bill and the intensity of transmitted light. By this detection, the size of the ticket, the shape such as torn, the transport state such as skew,
The degree of dirt is detected.

The magnetic sensor 12 detects the magnetism of the bill while being pressed by the roller 4. Reflection sensor 13
Reference numerals a and 13b each include an LED of a light emitting element and a diode of a light receiving element, and are provided on both sides of the transport path 2 to detect a front and back pattern of a bill.

The light receiving element 14 detects passage of a bill by using light from the reflection sensor 13b, and can obtain positional information of the bill required in each detection system. The reference roller 5 is a metal roller serving as a reference for thickness detection.
Is a roller for detecting the thickness of a banknote formed of a bearing. The detection roller 8 is attached to the lever 15, sandwiches a bill between the reference roller 5, and detects the thickness of the bill by measuring the rising amount of the lever 15. The rising amount of the lever 15 is determined by a thickness detecting sensor 16 composed of a potentiometer.
Is measured by detecting a minute rotation angle of the lever 15 in the step S1.

The analog board 17 is a board on which a circuit for amplifying or correcting the output of each sensor and performing preprocessing of the sensor output such as A / D conversion is mounted. The analog board 17 is provided with various volumes and test pins for adjusting the sensor output. The means for storing the sensor output correction (calibration) information is performed by a ROM provided on the analog board 17.

Next, a method of correcting thickness detection using a reference note (test note) as a reference medium according to the present invention in such a configuration will be described. A conventional reference ticket for thickness detection uses, for example, a 100 μm-thick paper or a plastic film such as polyester cut to the size of a banknote. The actual thickness is the thickness of the material at the time of manufacture,
The thickness varies from one sheet to another, and the thickness changes even if the material opening is different. For this reason, conventionally, a large number of reference bills have been used in a banknote inspection device and calibrated on the assumption that the average thickness of these reference bills is 100 μm. For this reason, it did not mean that calibration was actually performed using a ticket having a thickness of 100 μm.

According to the correction method of the present invention, the reference note is provided with means for recording thickness data, the thickness is measured one by one in advance, and the thickness data as a measurement result is written in the reference note. I have. Therefore, the thickness data of the reference note is read at the time of the calibration of the thickness detection of the banknote inspection device 1, and the gain of the thickness detection system is corrected by the read data and the thickness detection output detecting the reference note. Actually, since there is a variation in the output of the sensor system when the same reference ticket is inserted, a certain number of predetermined sheets are inserted, and the amount of gain correction takes the average value.

FIG. 2 shows an example of a reference note for calibration of the thickness detecting sensor 16. FIG. 2A shows a reference note on which magnetic recording is performed, and has a thickness of 102 μm and is magnetically recorded. FIG. 2B shows a reference ticket on which optical recording (printing) has been performed.
The printed thickness is 102 μm.

In FIG. 2 (a), a magnetic material is applied to four positions that can be read by the magnetic sensor 12 of the bill validator 1 in a part of the reference ticket, and the thickness is determined by the presence or absence of the four signals. Record the data. The writing of the thickness data is performed by a device having a thickness measuring machine and a head for magnetic recording.

The thickness data is, for example, a reference thickness 100
It is allocated as shown in FIG. 3 as a variation (difference) from μm. In FIG. 2A, for example, the thickness of the reference ticket is 10
If it is measured as 2 μm, the difference from 100 μm is “2”, so the corresponding data “1010” shown in FIG.
Is recorded on the reference ticket depending on the strength of the magnetic field. The thickness data thus recorded magnetically is stored in the magnetic sensor 1 of the banknote inspection device 1.
2 is read as reading means, and it is read that the thickness of the reference ticket being transported on the transport path 2 is 102 μm,
Calibration of thickness detection can be performed by associating the sensor output with the sensor output detected by the thickness detection sensor 16 as a detection unit.

FIG. 2B shows the case of optical recording, which can be read by the transmission sensor 11 of the banknote inspection device 1. The thickness data is recorded by printing or filling the reference ticket. For example, if the thickness of the reference note is measured to be 102 μm, the difference from 100 μm is “2”, so the corresponding data “1010” shown in FIG. 3 is printed.
That is, the “white square / black square” is printed or a part of the white square is painted black and recorded on the reference ticket. The thickness data recorded in this manner is used for the bill inspection device 1
The transmission sensor 11 as a reading unit,
The thickness of the reference note being conveyed is read to be 102 μm, and the thickness detection can be calibrated by making it correspond to the sensor output detected by the thickness detection sensor 16 as the detection means.

As described above, by recording the physical quantity such as the thickness of the reference note as a difference from the reference value, a fine value can be easily recorded as data. Further, there is no need to stick to the reference thickness of 100 μm. Therefore, it is possible to use a material that can be manufactured with a relatively stable reference ticket thickness and a material with high marketability. For example, if there is a magnetic medium having a suitable thickness on the entire surface, the data may be magnetically recorded and used as a reference ticket for the thickness.

In the above description, the thickness data reading unit is the thickness detection sensor 16 of the banknote inspection device 1. However, the thickness data may be written and read by a special adjustment device for manufacturing.

When the data reading section is provided in the dedicated adjusting device, the data recording method need not be readable by the bill validator 1. In such a case, a dedicated writing unit and reading unit such as a barcode may be provided. in this case,
Since the amount of data that can be recorded can be increased, it is also possible to use a single reference ticket for thickness detection and magnetic detection without using a dedicated reference ticket.

The measurement of the thickness of the reference medium (reference ticket) and the writing of the thickness data may be performed by a dedicated device, or the calibrated reference bill inspection device 1 may be used. The reading of the data may be performed by the adjusting device, or may be performed by the calibrated bill inspection device 1. For this purpose, the data recording means of the reference ticket may be selected so that sensor data other than the detection sensor to be calibrated can be read.

In the correction method of the present invention, since the thickness of each reference note is measured, even if the thickness of the reference note varies, it does not affect the calibration accuracy or the number of sheets to be inserted. In other words, since the thickness data of each reference note is written in advance in each ticket and read out at the time of calibration to calibrate the detection system, accurate calibration is performed even if the thickness of the reference note varies. be able to.

Further, since it is not necessary to suppress the variation in the thickness of the reference ticket, even if a data recording means is added, the manufacturing cost and management cost of the reference ticket can be reduced in total.
The case where the correction is performed in the inspection adjustment process of the banknote inspection device 1 has been described above. In the configuration in which thickness data is read by the banknote inspection device 1 in this manner, even after the adjusted banknote inspection device 1 is mounted on the banknote processing device main body or when it is used in the field, recalibration of thickness detection and Confirmation can be performed.

For example, when confirming the thickness detecting portion in the field, a thickness reference ticket is inserted, and the output value of the thickness detection sensor or the determination result of the thickness detection and the thickness data recorded in the reference ticket are input. Is performed by the test program of the banknote inspection device 1, it is possible to determine whether the calibration or the output is normal without observing the output waveform. Periodic inspection of thickness detection can be performed easily and reliably.

By the way, the adjusting device and the thickness measuring section may be constituted by using a reference banknote inspection device.
FIG. 4 shows an example in which an adjustment device is configured using a reference bill inspection device. That is, the adjusting device 20
Is a feeder unit 21 for taking in a reference ticket, a banknote inspection device 30 serving as a reference, a writing unit 22 for writing data, a reading unit 23 for reading data, and a banknote inspection device 4 to be adjusted.
0 and a stacker unit 24 for accumulating reference tickets.

The adjusting device 20 has a data calculating unit 2.
6, a control unit 25 including a determination unit 27 and a calibration unit 28 is connected. Reference banknote inspection device 30
Are connected to the thickness detection sensor 32, the data calculation unit 26 of the control unit 25, and the writing unit 22. Also,
The determination unit of the control unit 25 includes the reading unit 23, the magnetic sensor 41 of the banknote inspection device 40 to be adjusted, and the thickness detection sensor 4
2 are connected. Further, the determination unit 27, the calibration unit 2
8, and the analog board 4 of the banknote inspection device 40 to be adjusted
3 are connected.

Next, in such a configuration, the adjusting device 2
The adjustment operation at 0 will be described. First, the feeder unit 21
And a reference ticket is taken in from the banknote inspection device 30.

The thickness detection sensor 32 of the banknote inspection device 30
Detects the thickness of the reference ticket being conveyed, and outputs the output value to the data calculation unit 26. The data calculation unit 26 calculates the thickness data of the reference note based on the output value of the thickness detection sensor 32, and outputs the calculated thickness data to the writing unit 22.

The reference note conveyed in the bill inspection device 30 is conveyed through the thickness detecting sensor 32 and then further conveyed through the writing unit 22 and the reading unit 23. The writing unit 22 magnetically records the thickness data from the data calculation unit 26 on the transported reference ticket. The reading section 23 reads the thickness data of the reference ticket magnetically recorded by the writing section 22 to be conveyed, and
Output to

After the reference ticket is read by the reading unit 23,
Further, the paper money is conveyed in the bill inspection device 40 to be adjusted. The magnetic sensor 41 of the banknote inspection device 40 reads the thickness data of the reference ticket magnetically recorded by the writing unit 22 being conveyed, and outputs the data to the determination unit 27. An output value of the detected thickness is output to the determination unit 27.

The judging section 27 compares and judges the thickness data read by the reading section 23 or the thickness data read by the magnetic sensor 41 with the thickness data calculated from the output value detected by the thickness detecting sensor 42. And the result is sent to the calibration unit 28
Output to

The calibration unit 28 calculates calibration information of the detection output of the thickness detection sensor 42 from the result of the comparison and outputs the calibration information to the ROM provided on the analog board 43 of the banknote inspection device 40 to be adjusted.

In this way, the calibration (correction) information of the output of the thickness detection sensor 42 is stored in the ROM provided on the analog board 43, and the adjustment of the banknote inspection device 40 is completed. In the banknote inspection device 40 that has completed the adjustment, the detection output from the thickness detection sensor 42 is calibrated by the calibration (correction) information stored in the ROM provided on the analog board 43 at the time of banknote inspection.

In the adjusting device 20, data writing of the reference note is performed by the reference bill inspection device 30 and the writing unit 22. The calibration (correction) of the banknote inspection device 40 to be adjusted is performed by the thickness data read by the reading unit 23 or the banknote inspection device 4.
This is performed based on the thickness data calculated from the output value detected by the thickness detection sensor 42 of 0.

With such a configuration, various detections such as thickness detection, magnetic detection, shape detection, and dirt detection can be calibrated by unifying the data recording method to magnetic recording or using the above-described barcode. . It is also possible to combine two or more reference tickets so that the detection can be calibrated.

It is also possible to check whether or not the reference note has deteriorated based on the output waveform from the reference bill inspection apparatus 30. A reference ticket (reference medium) is deteriorated, and for example, a reference ticket having a thickness increased by "wrinkles"
You can check this or rewrite the data again. Thus, the reference medium can be managed.

In the above embodiment, the thickness is detected. However, the present invention can be applied to a reference ticket for other detection. This is particularly advantageous when a reference ticket cannot be created by specifying physical properties. For example, the same dirt cannot be made with a dirt reference ticket. A certain dirty ticket is prepared, read by, for example, a transmission sensor of the above-described reference banknote inspection device, and the output of the transmission sensor is written as reference data, thereby making it a reference ticket for contamination.

Further, a reject code is written on a special ticket (a reference ticket that generates a specific reject), and a test for confirming the operation can be performed by comparing the reject code with the reject code determined by the bill inspecting device to be adjusted. This can also be used to check functions during maintenance.

As described above, according to the embodiment of the present invention, the physical property value of the medium to be adjusted is recorded on each of the reference media (the reference voucher and the test voucher) and is used as the calibration information. Therefore, highly accurate calibration can be performed regardless of variations in the reference medium. In addition, since it is not necessary to suppress variations in the reference medium, the manufacturing cost of the reference medium can be reduced.

Since it is not necessary to insert a large number of sheets in order to eliminate the influence of variations in the reference medium, the amount of the reference medium used can be reduced, and the correction time can be shortened. There is.

By reading the physical property values of the reference medium recorded by the bill checking apparatus, the correction can be performed by the bill checking apparatus itself. Not only adjustment and correction of the banknote inspection device, but also confirmation of the completed banknote inspection device can be performed with the banknote processing device mounted.

It is also possible to confirm and manage the physical property values due to the deterioration of the reference medium, or to overwrite the changed physical property values and continue using them. Thus, calibration can be performed with high accuracy and economically. In addition, it can be used not only for calibration but also for maintenance such as confirmation of the banknote inspection device after adjustment.

It is possible to provide a banknote inspection device and a correction method for the banknote inspection device, which can reduce the usage amount of a banknote reference medium and perform highly accurate calibration.
