Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a banknote pay-in / pay-out machine used in financial institutions and the like and a banknote processing method therefor.

[0002]

2. Description of the Related Art Conventionally, a banknote depositing / dispensing machine used in a financial institution uses a banknote depositing / dispensing machine. In the banknote depositing / dispensing machine, a depositing operation, a replenishing operation, a dispensing operation, a collecting operation, Each operation such as a scrutiny operation is performed. Then, in the deposit operation, the bills inserted into the customer service unit are sent to the bill discriminating unit, in the replenishment operation, the bills set in the replenishment and collection unit are sent to the bill discriminating unit, and in the dispensing operation, the bills are The banknotes stored in the stacker are sent to the banknote discriminating unit by the specified amount, and in the collecting operation, the banknotes stored in the banknote stacker are sent to the banknote discriminating unit, and the running state of the banknotes by the banknote discriminating unit, The denomination, authenticity, and the like are determined. In addition, when a running abnormality of a bill occurs or the bill is determined to be a fake bill,
Each bill is rejected and sent to the reject unit, and the amount of the bill is added to the reject amount MR of the bill in the reject unit.

[0003] In the scrutiny operation, the control unit:
First, the amount changed by the depositing operation, the replenishing operation, the dispensing operation, and the collecting operation from the previous inspection or the new use to the present time is calculated, and the balance M1 of the bills in the bill dispensing machine is calculated. Next, the banknotes in the banknote stacker are conveyed to the replenishment unit by the same operation as the collection operation, and the balance M2 is obtained. In this case, the balances M1 and M2 of the bills do not match when there is a bill stored in the reject unit. Therefore, the reject amount MR of the banknote in the reject unit is checked to confirm that M1 = M2 + MR.

[0004] Incidentally, banknote running abnormalities include approach, excessive skew, and heavy running. The approach is a running abnormality that occurs when a bill is conveyed at an interval shorter than a standard bill interval.If the approach occurs, the next denomination of the previous bill is not completed before discrimination of the denomination, authenticity, etc. is completed. Will arrive, and accurate discrimination cannot be performed. Therefore, when the bill discriminating unit determines that an approach has occurred by examining the interval between the bills that have passed through the trigger sensor, the bill is rejected and sent to the rejecting unit. Only judgment is performed.

[0005] The excessive skew is a running abnormality that occurs when a banknote is conveyed while being inclined from a preset skew value.
Not only will it be impossible to normally convey the bills, but also the bill discrimination unit will not be able to accurately determine the denomination, authenticity, and the like. Therefore, the bill discrimination unit
When it is determined that excessive skew has occurred based on the time lag when the arrival of the bill is detected by the trigger sensor, the optical sensor, or the like, the bill is rejected and sent to the reject unit, and the authenticity is not determined. Only the determination is made.

In this case, the banknote pattern data is corrected and calculated based on the skew angle, thereby converting the banknote pattern data into data corresponding to the banknote inclination to determine the denomination. Furthermore, the heavy running is a running abnormality that occurs when a plurality of bills are conveyed in a stack, and when the heavy running occurs, it is necessary to accurately determine a denomination, authenticity, and the like, depending on how the bills overlap. Can not be done. Therefore, the bill discriminating unit detects the thickness of the bill by the thickness detection sensor, and when determining that the overrun has occurred, rejects the bill and sends it to the rejecting unit, without performing the true / false determination. Only the denomination is determined.

[0007] In this case, the denomination of the denomination of the banknotes is performed independently for the front and back sides of the banknotes, and the denominations of the two banknotes that have been run in a long run are determined based on the discrimination results of the front and back denominations. ing. As a result, 2 rejected due to heavy running
The denomination of the banknote is determined. in this way,
When a bill running abnormality occurs, the control unit can recognize the denomination and the number of bills sent to the reject unit, and the amount of the bill newly sent to the reject unit is added to the reject amount MR. Is done.

[0008]

However, in the above-described conventional banknote pay-in / pay-out machine, approach, excessive skew and heavy running can be detected, but two banknotes are conveyed in a shifted state and stacked. In other words, when a banknote chain occurs, the denomination cannot be determined.

Therefore, the control unit cannot recognize the denomination and the number of bills sent to the reject unit by the chain, and cannot obtain the amount of the bills newly sent to the reject unit. The reject amount MR cannot be checked. The present invention solves the problems of the conventional banknote pay-in / pay-out device, and provides a banknote pay-in / pay-out device and a banknote processing method capable of accurately obtaining all the amounts of banknotes rejected due to all running abnormalities. The purpose is to:

[0010]

For this purpose, in the bill receiving / dispensing machine of the present invention, a length detecting means for detecting the length of the bill in the conveying direction, and a thickness detecting means for detecting the thickness of the bill. And length determining means for determining whether the length of the bill detected by the length detecting means is greater than a set value, and the pattern of the thickness of the bill detected by the thickness detecting means, Condition determining means for determining whether or not a condition at the time of occurrence of a chain is satisfied, and a length of a bill detected by the length detecting means being larger than a set value, and a bill detected by the thickness detecting means A chain judging means for judging that a chain of banknotes has occurred when the pattern having the thickness of を 満 た す satisfies the condition when the chain of banknotes occurs.

In the bill processing method of the bill receiving / dispensing machine according to the present invention, the length of the bill in the transport direction is detected, the thickness of the bill is detected, and the length of the detected bill is larger than a set value. It is determined whether or not the detected thickness pattern of the banknotes satisfies the condition at the time of the generation of the banknote chain. And when the length of the detected bill is greater than the set value, and the pattern of the detected thickness of the bill satisfies the condition when the chain of bills occurs,
It is determined that a banknote chain has occurred.

FIG. 10 is a second diagram showing a state of the chain of banknotes according to the first embodiment of the present invention. 7 to 9, the horizontal axis represents the length L, and the vertical axis represents the sensor output t. FIG. 10A is a diagram showing a state of a first chain, and FIG. 10B is a diagram showing a state of a second chain.

First, the bill 25 is added to the bill discriminating section 13 (FIG. 3).
Is sent, the CPU 20 (FIG. 1)
1 detects the arrival of the bill 25, and detects the thickness detection sensor 22, the magnetic sensor 24, and the optical sensors 26 and 27.
Of the bill 25 based on each position of the
Is the thickness detection sensor 22, the magnetic sensor 24, and the optical sensor 2.
The timing of passing through the sensors 6 and 27 is set, and each sensor output is read at each timing.

The length determining means 33 of the CPU 20 detects the length of the bill 25 in the transport direction as shown in FIG. 5, ie, the length L1 in the short direction, based on the sensor output of the trigger sensor 21. , the length L1, which is detected to determine whether greater than the set value L _r. And the length L1
When There is less than a set value L _r, CPU 20 is approaching, skew excessive performs heavy run like running abnormality other than a chain of determination and denomination determination, if the determination result is normal, the denomination The discrimination result is sent to a control unit (not shown) of the banknote pay-in / pay-out device 11 (FIG. 2). If each determination result is not normal, C
The PU 20 rejects the banknote 25 and rejects the banknote 25.
Send to The set value _Lr is set in accordance with the measured length of one bill 25 in the short direction.

On the other hand, when the length L1 is larger than the set value L _r, CPU 20, in order to determine whether the chain shown in FIG. 6 has occurred, reads the sensor output t of the thickness detecting sensor 22 , It is checked whether the sensor output t satisfies the chain condition. For this purpose, the slice levels t _{1 to} t _{3 of} the sensor output t are set in advance in accordance with the thicknesses of one to three bills 25.

For example, when the bill 25 having the length L1 is normally conveyed, as shown in FIG.
Is t ₁ <t <t ₂ for the length L ₁ , and when the banknote 25 is running multiple times, as shown in FIG. 8, the sensor output t becomes t ₂ <t for the length L 1. <become t _3.

When a chain occurs in the banknotes 25, the first banknote 25 has a rear end above the front end of the second banknote 25 as shown in FIG. And the second chain state in which the rear end of the first bank note 25 is below the front end of the second bank note 25. Therefore, from the front end of the first sheet of bill 25 to the front end of the second sheet of bill 25 length L and L _1, the length from the front end of the first sheet of bill 25 to the rear end of the first sheet of bill 25 Let L be L ₂ and 1
When th to the rear end of the second sheet of bill 25 from the front end of the bill 25 to the length L was set to L _3, the chain occurs in the bill 25, the L _r <L _3.

The sensor output t satisfies t ₁ <t <t ₂ (1) in the range of 0 <L <L ₁ , and t ₂ <t <in the range of L ₁ <L <L ₂ t ₃ (2), and t ₁ <t <t ₂ (3) in the range of L ₂ <L <L ₃ . _{Further, L 2 = (L 3 -L} 1) = L r ... relationship (4) is satisfied.

Therefore, the above equations (1) to (4) are set as chain conditions, and the condition determining means 34 of the CPU 20 determines that the sensor output waveform, that is, the pattern of the thickness of the bill 25 satisfies the above conditions. Determine whether or not. And CP
If the length L1 is larger than the set value _Lr and the thickness pattern of the banknotes 25 satisfies each of the above conditions, the chain determination unit 35 of U20 determines that the banknotes 25 are chained. If the thickness pattern of the bill 25 does not satisfy the above conditions, the CPU 20 rejects the bill 25 and sends it to the reject unit 16.

Next, the denomination determining means (not shown) of the CPU 20 estimates the outer shape of the banknote 25 by reading the sensor outputs of the optical sensors 26 and 27 and assumes the state of the chain to determine the denomination of the banknote 25. Make a determination. If the determination result is normal, the CPU 20 sends the denomination result to the control unit. If the determination result is not normal, the CPU 20
Rejects the bill 25 and sends it to the reject unit 16.
The control unit is configured to perform a bill discrimination unit 1 based on a denomination discrimination result.
3 is subtracted from the balance of the bill stacker 15 and added to the reject amount MR.

As described above, when the chain of the banknotes 25 occurs, the denomination can be determined, so that the control unit recognizes the denomination and the number of the banknotes 25 sent to the reject unit 16 by the chain. be able to. Therefore, the amount of the bill 25 newly sent to the reject unit 16 can be obtained, and the reject amount MR can be checked.

It should be noted that, based on the sensor outputs of the optical sensors 26 and 27 with and without the bill 25, the bill 25
The slice level for estimating the outer shape of is determined in advance and stored in the memory 31. Next, the flowchart will be described. Step S1 The length determining means 33 of the CPU 20 determines that the bill 2
The lateral direction of 5 the length L1 is compared with the setting value L _r. Step S2 length L1 to determine whether greater than the set value L _r. To step S6 if the length L1 is larger than the set value L _r, if the length L1 is equal to or smaller than the set value L _r, the process proceeds to step S3. In step S3, a traveling abnormality other than the chain and a denomination are determined. Step S4: It is determined whether or not the results of the determination of the running abnormality other than the chain and the determination of the denomination are normal. If the determination of the traveling abnormality other than the chain and the determination of the denomination are normal, the process proceeds to step S5, and if not, the rejection ends. Step S5 The denomination determination result is sent to the control unit, and the process ends normally. Step S6 The sensor output t of the thickness detection sensor 22 is read. Step S7: It is determined whether or not the sensor output t satisfies the chain condition. If the condition of the chain is satisfied, the process proceeds to step S8, and if not, the rejection ends. Step S8: The outer shape of the banknote 25 is estimated. Step S9 The denomination is determined by assuming the state of the chain shown in (a) and (b) of FIG. Step S10: To judge whether the denomination result of the denomination is normal. If the denomination result is normal, step S1
Proceed to step 1. If not, the rejection ends. Step S11 The result of the denomination determination is sent to the control section, and the rejection is terminated.

Next, a method of determining a denomination will be described.
FIG. 11 is a flowchart showing the operation of discriminating the denomination in the first embodiment of the present invention, FIG. 12 is a diagram showing a scanning state of a 1,000 yen note in the first embodiment of the present invention, and FIG. FIG. 14 is a diagram showing a scanning state of a 5,000 yen note in the first embodiment of the present invention, FIG. 14 is a diagram showing a scanning state of a 10,000 yen note in the first embodiment of the present invention, and FIG. FIG. 16 is a diagram showing a sensor output level when a 1,000 yen note is scanned in the embodiment of FIG. 16, and FIG. 16 is a diagram showing a sensor output level when a 5,000 yen ticket is scanned in the first embodiment of the present invention. FIG. 17 is a diagram illustrating a sensor output level when a ten thousand yen note is scanned according to the first embodiment of the present invention. 15 to 17, the horizontal axis represents the scanning direction and the vertical axis represents the sensor output.

In this case, based on the detection results of the optical sensors 26 (FIG. 3), 27, a plurality of characteristic points A, which are characterized by the shading of the printing pattern of the bill 25 for each denomination,
B are set in advance, and each feature point A,
The slice levels a, b,... For slicing the sensor outputs in B,. Then, for example, since each feature point A in FIGS. 12 and 14 is set in the watermark portion of the 1,000 yen note and the ten thousand yen note, respectively, FIGS.
As shown in the figure, the sensor output of each feature point A becomes larger than the slice level a. On the other hand, since the feature point A in FIG. 13 is located in the character portion of the 5,000 yen ticket, as shown in FIG.
Is smaller than the slice level a. Therefore, the sensor output of the feature point A is compared with the slice level a, and when the sensor output is equal to or lower than the slice level a, the banknote 25 is determined to be a 5,000 yen note, and the sensor output is equal to or higher than the slice level a. In some cases, by comparing the sensor output of another feature point B with the slice level b, it is determined whether the banknote 25 is a 1,000 yen note or a 10,000 yen note.

When the denomination is thus determined, in order to determine whether or not the bill 25 is normal,
The data of the normal banknote 25 stored in the memory 31 in advance for each denomination and the data of the print pattern of the banknote 25 read by the optical sensors 26 and 27 are collated on the entire surface of the banknote 25, and whether they match each other. Find out if. In the present embodiment, in the case of the first chain state as shown in FIG. 10A, and in FIG.
It is assumed that there is a second chain state as shown in FIG.

For example, when the bill 25 is in the first chained state, the optical sensor 2 disposed above the bill transport path 18
When the print pattern of the banknote 25 is read by 6, the first banknote 25 becomes normal, but the second banknote 25 becomes abnormal. On the other hand, when the print pattern of the bill 25 is read by the optical sensor 27 disposed below, the first bill 2
5 becomes abnormal, but the second bill 25 becomes normal.

When the print pattern of the bill 25 is read by the optical sensor 26 when the bill 25 is in the second chain state, the first bill 25 becomes abnormal.
The bill 25 becomes normal. On the other hand, the optical sensor 27
When the printing pattern of the bill 25 is read, the first bill 25 becomes normal, but the second bill 25 becomes abnormal.

Therefore, in the present embodiment, the bill 25 is determined based on the print pattern of the bill 25 read by at least one of the optical sensors 26 and 27.
Is determined to be normal, the determination result of the denomination of each banknote 25 is sent to the control unit. Next, the flowchart will be described. Step S21: The sensor output of the feature point A is compared with the slice level a to determine whether the sensor output is larger than the slice level a. If the sensor output is higher than the slice level a, the process proceeds to step S23. If the sensor output is lower than the slice level a, the process proceeds to step S22. Step S22: It is determined that the bill 25 is a 5,000 yen note. Step S23: The sensor output of the feature point B is compared with the slice level b to determine whether the sensor output is larger than the slice level b. If the sensor output is higher than the slice level b, the process proceeds to step S25. If the sensor output is lower than the slice level b, the process proceeds to step S24. Step S24: It is determined that the banknote 25 is a 10,000 yen note. Step S25: It is determined that the banknote 25 is a 1,000 yen note.

Next, a second embodiment of the present invention will be described. FIG. 18 is a diagram showing an arrangement state of a trigger sensor and a thickness detection sensor according to the second embodiment of the present invention,

FIG. 23 is a diagram showing a state of a second chain of bills according to the second embodiment of the present invention. Note that FIG.
At 0 and 21, the horizontal axis represents the length L and the vertical axis represents the sensor output t. The components having the same structure as that of the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

In this case, a plurality of (for example, two) first and second trigger sensors 21a and 21b as length detecting means are provided in a direction perpendicular to the direction of transport of the bill 25, and First and second in the transport direction of the bill 25
Downstream of the first and second trigger sensors 21a, 21b, the first and second thickness detection sensors 22a, 22
b are respectively disposed, and the first scan line A is moved by the second trigger sensor 21b and the second thickness detection sensor 22b by the first trigger sensor 21a and the first thickness detection sensor 22a. Two scanning lines B are respectively set.

Therefore, when a chain as shown in FIG. 19 occurs in the banknote 25, the first scanning line A in FIG.
0 is output from the second scanning line B
In FIG. 21, sensor output waveforms as shown in FIG. 21 are respectively formed. Therefore, 1 on the second scan line B
When the front end of the second banknote 25 is set as a reference position, the first banknote 2 on the first scan line A from the reference position.
5 until the front end of the length L and L _4, from the reference position to the length L to the front end of the second sheet of bill 25 in the first scan on the line A and L _5, from the reference position first Length L to the rear end of the first bill 25 on the scanning line A
Is L ₆ , the length L from the reference position to the rear end of the second bill 25 on the first scanning line A is L _7, and 1 is the length from the reference position to the second scanning line B on the second scanning line B.
Th to the rear end of the bill 25 length L and L _8, the length L from the reference position to the front end of the second sheet of bill 25 in the second scan line on B and L _9, the reference the length L to the rear end of the second sheet of bill 25 in the second scan line on B and L ₁₀ from the position, when the setting value was set to L _r, the chain of the bill 25 is generated, L _r <L _Will be ₁₀ .

The sensor output t satisfies t ₁ <t <t ₂ (5) in the range of L ₄ <L <L ₅ , and t ₂ <t in the range of L ₅ <L <L _6. <becomes t ₃ ... (6), in the range of _{L 6 <L <L 7,} t 1 becomes _{<t <t 2 ... (7} ). Further, the following relationship is established: (L ₆ −L ₄ ) = (L ₇ −L ₅ ) = L _r (8)

Therefore, in at least one of the first and second thickness detecting sensors 22a and 22b, the above equations (5) to (8) are set as a chain condition. Determines that a chain of banknotes 25 has occurred. If the conditions are not satisfied, the CPU 2
0 rejects the banknote 25 and sends it to the reject unit 16 (FIG. 2).

After the denomination is determined, the bill 2
In order to determine whether or not No. 5 is normal, data of a normal banknote 25 stored in advance in a memory 31 (FIG. 1) for each denomination and an optical sensor as first and second print pattern reading means Banknote 2 read by 26 and 27
The data of the print pattern No. 5 is compared with the entire surface of the banknote 25, and it is checked whether or not the two match. In the present embodiment, it is assumed that there is a case of the first chain as shown in FIG. 22 and a case of the second chain as shown in FIG.

For example, when the bill 25 is in the first chained state, the optical sensor 2 disposed above the bill transport path 18
When the print pattern of the banknote 25 is read by 6, the first banknote 25 becomes normal, but the second banknote 25 becomes abnormal. On the other hand, when the print pattern of the bill 25 is read by the optical sensor 27 disposed below, the first bill 2
5 becomes abnormal, but the second bill 25 becomes normal.

When the bill 25 is in the second chain state, when the print pattern of the bill 25 is read by the optical sensor 26, the first bill 25 becomes abnormal.
The bill 25 becomes normal. On the other hand, the optical sensor 27
When the printing pattern of the bill 25 is read, the first bill 25 becomes normal, but the second bill 25 becomes abnormal.

Therefore, in the present embodiment, when the banknote 25 is determined to be normal based on the print pattern read by at least one of the optical sensors 26 and 27, the denomination of each banknote 25 is determined. Is sent to the control unit. In each of the above embodiments, the banknote 25 in which the front and back and the top and bottom are unified when performing the denomination determination is illustrated. However, even when the front and back and the top and bottom are not unified, the feature points A, B, and .. Can be accurately determined by appropriately setting...
