Description

TECHNICAL FIELD The present invention relates to an automatic teller machine, and in particular, when old bills are mixed even when old bills are almost entirely new bills. The present invention relates to an automated teller machine such as an automatic teller machine or an automatic money changer that can be safely and reliably processed.

[Background of the Invention]

As a result of the issuance of new circulation banknotes on November 1, 1984, after that, each financial institution has installed an automated teller machine that can use both old and new banknotes. Since the Bank of Japan is exchanging old bills for new bills, the new bills will occupy the majority in a few years, and as a result, the automated teller machine will also
Some years later, it seems that only new bills will appear. That is, since the new bill is smaller in manufacturing, the bill discriminating performance is improved and the device can be downsized when the new bill dedicated device is used. However, even if many years pass, old bills are also circulating bills, and therefore old bills may be mixed in bills. If an old bill having a size larger than that of the new bill is taken into the device dedicated to the new bill, there is a possibility that a jam occurs in the transport path or the bill is damaged.

Hereinafter, the structure and operation of the conventional cash transaction device (hereinafter referred to as ATM) will be described in detail.

FIG. 3 is a side sectional structural view of a conventional ATM. Conventional ATM
As mentioned above, to handle both old and new banknotes,
The banknote entrance, the transportation path, and the safe are installed in accordance with the old banknote with a large banknote size. 1 is a banknote deposit / withdrawal port, 2 is a banknote discriminating section, 3 is a safe deposit box, 4 is a temporary deposit safe, 5 is a display section, 6 is a safe box for each denomination, 7 is a control and power supply section.

The banknote 11 that was deposited by the depositor as a bundle for deposit is
The bills are conveyed one by one from the bill deposit / withdrawal port 1 and reach the bill validator 2. The authenticity determination and the denomination determination are performed by the discriminating unit 2, the genuine bill is stored in the temporary deposit safe 4, and the counterfeit bill is the reject safe 3
To be stored in each. At the same time, the amount of money discriminated by the discriminating unit 2 is displayed on the display unit 5, so that the depositor collates the displayed amount of money with the amount of money he has put in, and pushes the confirmation button or the like from the temporary deposit safe 4. It is either transferred to the cash box 6 of the denomination or returned to the banknote deposit / withdrawal port 1 from the temporary deposit vault 4 by pressing the cancel button or the like, and handed to the depositor.

FIG. 4 is a schematic plan cross-sectional view in the transport path of the bill discriminating unit in FIG. 12 is a conveyance path, 13 is a watermark pattern detection sensor for authenticity determination, 11 is a bill conveyed at the correct position, 11
Reference numeral -2 indicates a bill that has been misaligned and conveyed, and reference numeral 14 indicates a watermark portion of the bill.

As shown in FIG. 4, the banknote 11 conveyed from the banknote deposit / withdrawal port 1 advances in the direction of arrow A in the discrimination section 2 and is conveyed in the lateral direction of the banknote 11.

Since the bill 11 is meandering (Slalom) or shifting (Shift) while being transported on the transport path up to the discrimination unit 2, the width W of the bill 11 is W.
₂ has a margin on both sides, and a conveyance path 12 having a width W ₁ with about 10 mm added on both sides is provided. In addition, since both old and new circulating banknotes are handled, the width W ₁ of the transport path 12 is set to a value in consideration of the case where a banknote having the largest longitudinal dimension among the circulating banknotes passes through.

FIG. 5 and FIG. 6 are explanatory diagrams of external dimensions of old and new circulating banknotes.

As shown in FIGS. 5 and 6, the oldest 10,000-yen bill, the oldest 5000-yen bill, the old 1,000-yen bill, the new 10,000-yen bill, and the new 5000-yen are the largest in the longitudinal dimension. The yen bills and the new thousand yen bills are becoming smaller in this order. Further, in the dimension in the widthwise direction, the old 10,000 yen bill, the old 5,000 yen bill, and the remaining all denominations of tickets have become smaller in this order. That is, as is apparent from FIG. 6, the new bill has the same dimension in all the denominations in the lateral direction, and has the same dimension as the old 1,000-yen bill. Therefore, the transport path width W ₁ of the transport path 12 in FIG. 4 is set in accordance with the old ten thousand yen bill having the largest longitudinal dimension.

The genuineness / counterfeit detection sensor 13 for determining authenticity of bills provided in the central portion of the transport path 12 in FIG. 4 is provided at the center of the bill 11 when the bill 11 conveyed thereon passes. The watermark pattern of the portrait portion 14 is optically detected and collated with the watermark pattern previously stored in the control / power supply unit 7 and a storage unit (not shown) shown in FIG. Determine the species.

When the banknote 11 passes over the authenticity detection sensor 13, meandering or left / right misalignment may occur during the period from the banknote deposit / withdrawal port 1 to the banknote discriminating section 2 or within the banknote discriminating section 2. It is normal.

FIG. 7 to FIG. 13 are explanatory diagrams of a pattern detection method in the case of a conventional banknote position shift, FIG. 7 is a plan view showing a watermark part of a banknote, and FIG. 8 is a watermark of FIG. FIG. 9 is an enlarged plan view showing a dividing line obtained by dividing the part by 1 mm, FIG. 9 is a waveform pattern of a watermark pattern detected in the central portion of the dividing line in FIG. 8, and FIGS. 10 to 13 are the dividing lines in FIG. It is a watermark pattern detection waveform diagram in the position shifted to the left and right from the center of the line.

Conventionally, in order to discriminate the banknote 11-2 which is displaced to the left and right, the regular watermark pattern signal waveform shown in FIG. 9 which optically detects the central pattern of the watermark in the central portion of the banknote of FIG. 7 is used. While memorizing, optically detect the watermark pattern on the line divided into 1 mm each from the center to the left and right,
It also stores those detection signals. FIGS. 10 to 13 show collation patterns in which a watermark portion having misalignment is detected by the authenticity detection sensor 13, and FIGS.
The pattern signals of the cuts F and R in the figure are shown, and FIGS. 11 and 13 are the pattern signals of the cuts A and Y in FIG. 8, and the amplitude of the pattern signal becomes smaller as it shifts from the center to both sides.

The width W ₁ of the transport path 12 is 174 mm, which is the maximum longitudinal dimension of the denominations to be handled (that is, the old 10,000-yen note), plus 10 mm of margin for shift and meandering amount when transporting bills. 184m
m.

In the enlarged view of the central watermark portion 14 shown in FIG. 8, lines divided by 1 mm from the center to the left and right are indicated by A to Z. The watermark pattern of each of these lines is optically detected, and the detection signal is stored. For example, in FIG. 9, the vertical axis represents the amplitude of the pattern detection signal, that is, the output signal amount, and the horizontal axis represents the time t from the start time. In reality, since the bill 11 is detected while traveling at a constant speed, the time on the horizontal axis corresponds to the position of the bill 11 in the lateral direction.
In addition, FIG. 10 shows that from the center of the watermark portion 14 of the bill 11
The detection signal of the watermark pattern at the position displaced by mm position (position of F line in FIG. 8) is shown in FIG. 11 which is displaced by 17 mm further left from the F line of FIG. 8 (A line of FIG. 8). Position) is a detection signal of the watermark pattern, and FIGS. 12 and 13 are detection signals of the watermark pattern at positions displaced by 17 mm to the right in the opposite direction to FIGS. 10 and 11, respectively ( R in Figure 8,
Y line position).

As is clear from FIGS. 9 to 13, the detected signal pattern at the center of the waveform, that is, the watermark portrait portion of FIG. The larger the displacement amount, the smaller the waveform shape and the more unclear. Therefore, the larger the lateral displacement of the conveyed banknotes 11 during conveyance, the worse the performance of the banknotes 11 for determining the authenticity and denomination, the risk of misjudgment, and the failure of the banknote discrimination function. That is, in the automatic cash handling apparatus, it is an important matter to reduce the amount of lateral deviation during transportation.

However, in the conventional device, since the banknotes with a large longitudinal difference in size are circulating among the old and new circulating banknotes, the banknotes can be transported according to the width (longitudinal size) of the large old 10,000 yen bill without stopping. A watermark pattern for checking the amount of positional deviation between the road and the left and right is stored. In other words, the new 1,000-yen bill with the smallest longitudinal dimension is transported to the transport path that matches the width of the old 10,000-yen bill. In this case, the width of the transport path is determined according to the least frequently used bill, and the most frequently used bill has the largest misregistration. In this case, the amount of misalignment of the New Thousand Yen bill is
W ₁ )-(longitudinal dimension of new 1000 yen bill) = 184-150 = 34 mm. If the positions are left and right evenly, the left and right positions will be displaced by 17 mm. And, in this case, too, so that it can be matched by the watermark pattern,
If the watermark pattern at the position cut at every 1 mm of misalignment is detected and stored in advance, for example, it is necessary to store 34 kinds of signal patterns only by collating new 1,000 yen bills.

FIG. 14 is a plan sectional view of the carrying surface in the worst case in FIG.

When the new 1,000-yen bill is transported with one end in contact with the end of the transport path 12, the position shift of the watermark portrait portion becomes maximum,
As shown in FIG. 14, the frame of the watermark portion of the banknote 11b is passed with the frame displaced. In this case, since the range in which the pattern can be detected exceeds the range, it is impossible to determine the watermark pattern.

In order to solve these problems, a new ticket exclusive for a new ticket with a narrow width of the conveyance path that can handle only new tickets with small longitudinal dimensions
It is possible to use ATM. However, if a depositor who does not know that it is an ATM that does not handle old bills accidentally inserts the old bill into the banknote deposit / withdrawal port, the banknote will be jammed due to the small conveyance path, causing jams. Alternatively, the bill may collide with the guides on the left and right of the transport path or the wall surface of the safe, and the bill may be damaged.

As a method of discriminating and taking in banknotes, conventionally, a method of discriminating by comparing a detection signal of a standard banknote stored in advance with a detection signal of a banknote to be discriminated (for example, Japanese Patent Publication No. 56-
16469), the outer dimensions are measured by optically detecting both edges of the bill to be discriminated, the comparison information between the reflection pattern and the reference pattern of the bill to be discriminated is obtained, and the logic of the dimension information and the pattern comparison information is obtained. How to determine the product (for example,
55-107681 gazette), when a bill is inserted, the pressing plate for pressing and pushing the bill is set to an inactive position to facilitate the insertion of the bill, and when the bill is taken in, the pressing plate is pushed and biased. To ensure capture (Japanese Patent Publication No. 56-
No. 50299 gazette), a storage box that collectively receives the inserted banknotes, a unit that takes in the banknotes one by one for post-processing, and a part of the storage box that forms the banknotes when the banknotes are taken in. ATM equipped with a back-up plate to be pressed against the take-in means (for example, see Japanese Utility Model Laid-Open No. 57-34053),
It is possible to insert all the banknotes to be deposited and all the banknotes to be deposited at once, and only the correct banknotes from the banknotes that have been deposited will be taken in as deposits, and the fraudulent or suspicious banknotes and the stacked banknotes will be returned to the entrance. There are known methods such as reinjection (see Japanese Utility Model Publication No. 55-31636). However, regarding the above-mentioned problems of old tickets and new tickets,
No consideration whatsoever.

Moreover, it is an object of the present invention to provide an automated teller machine which does not cause an obstacle even when an old bill is thrown in, and makes it possible to reduce the size of a transport path and various safes, thereby achieving downsizing and cost reduction.

[Outline of Invention]

In order to achieve the above object, an automatic teller machine of the present invention conveys a banknote deposit / withdrawal port (1) into which banknotes are inserted, and banknotes deposited into the banknote deposit / withdrawal port (1) one by one. In the automatic teller machine (8a) including a section (conveyance path 23) and a bill discrimination section (2a) for discriminating the denomination and authenticity of the bill conveyed by the conveyance section (conveyance path 23), A vibration exciter base mechanism section (21) that arranges the banknotes by vertically vibrating the banknotes deposited in the banknote deposit / withdrawal opening (1) and the banknotes arranged by the vibration exciter stand mechanism section (21). With respect to the depositor, the size is determined by a sensor (light detection sensor 24) that detects that the size exceeds the maximum value of the size of a preset type of banknote, and the detection output of this sensor (light detection sensor 24). Guidance table to remove and re-enter banknotes deposited in the banknote deposit / withdrawal slot (1) The display unit 5 shown is provided, and the conveyance unit (conveyance path 23) and the bill discriminating unit (2a) have a size corresponding to a bill having a size within the maximum value.

Example of Invention

An embodiment of the present invention will be described below in detail with reference to FIGS.

FIG. 1 is a side sectional view of an ATM showing an embodiment of the present invention.

In FIG. 1, 1 to 7 are the same as those shown in FIG. In FIG. 1, in addition, a vibrating vibrating table mechanism unit 21, a bill holding plate 22, and a light detection sensor 24 are newly installed near the bill depositing / dispensing port 1. AT in Fig. 1
The structural difference between the M8a and the conventional ATM8 shown in FIG. 3 is that, as described above, a mechanism for eliminating the positional deviation of the conveyed banknotes is provided in the adjacent portion of the banknote deposit / withdrawal port 1, and the positional deviation of the banknotes. This is to reduce the storage amount of the watermark check pattern.

That is, as shown in FIG. 1, the front table surface is provided with a banknote deposit / withdrawal slot 1 into which the deposited banknote bundle 11a is inserted. A vibration shaking table mechanism section 21 for adjusting is provided,
Further, a bill holding plate 22 for holding the deposited bill bundle 11a upright is attached so that the bill bundle 11a does not fall down during vibration. Banknote bundle 11a deposited in the banknote deposit / withdrawal port 1
The discriminating section 2a, the remittance safe box 3, the temporary deposit safe box 4, and the denomination-specific storage safe box 6 are conveyed by the conveying path 23 that conveys the sheets one by one.
Be transported to. Further, on the upper surface of the ATM 8a, there is a display unit 5 for displaying the amount of money, a matching result, a guidance sentence, etc., and behind it is a control / power supply unit 7 for controlling the entire device 8a. Will be placed. Further, inside the banknote deposit / withdrawal port 1, a pair of optical sensors 24 for detecting whether or not the height dimension, which is the lateral dimension of the deposited banknote bundle 11a, exceeds a reference value, is provided with a vibration sensor. It is mounted at a height of 77 mm from the swing mechanism part 21.

FIG. 2 is a plan cross-sectional view of the conveying surface of the discriminating unit in FIG.

The banknote 11 conveyed from the banknote pay-in / pay-out port 1 is conveyed in the arrow B direction of the banknote short-side direction and passes through the conveyance path 12 of the banknote discriminating unit 2a. A watermark pattern detection sensor 13 is provided on the watermark line of the bill 11 passing through the transport path 12. The width W ₃ of the conveying path 12 of the bill discriminating unit 2a is set to a value obtained by adding the meandering amount of 10 mm during conveyance to the longitudinal dimension of the old 1,000-yen bill, that is, W ₃ = 174 mm. This value is considerably smaller than the width W ₁ (184 mm) of the conveying path 12 of the conventional discrimination section 2 shown in FIG.

In this embodiment, the width of the conveyance path is reduced and
An optical sensor for detecting the short dimension of the bill 11 in the bill slot 1.
By providing 24, by detecting whether or not the upper end of the deposited banknote bundle 11a is projected longer than a specified length, a banknote with a large longitudinal dimension of banknotes, for example, an old 10,000-yen note, an old 5,000-yen note, is a depositor. Even if it is thrown in by mistaken insertion, it is possible to detect this and return it to the depositor. There is no danger of entering a department or various safes and causing an accident such as a jam.

Next, the operation in FIGS. 1 and 2 will be described.

Banknote bundle 11 deposited in the banknote deposit / withdrawal port 1 by the depositor
The a is vertically held by a bill holding plate 22 provided at the back of the bill deposit / withdrawal port 1, and the misalignment is corrected by the vibration of the vibration vibrating table mechanism portion 21 at the bottom. Then, the optical sensor 24 provided inside the banknote deposit / withdrawal port 1 detects whether or not the banknote bundle 11a has a height dimension (banknote lateral dimension) of 77 mm or more. If there are old ten thousand yen bills and old five thousand yen bills with long bill lengths in the bill bundle 11a, as shown in FIG. 6, the short dimension of each bill is 84 mm, 80 mm and their presence is detected by the optical sensor 24.
If a size shorter than 77 mm is detected, the ATM8
On the display section 5 provided at the top of a, the message "Old 10,000 yen bills and old 5,000 yen bills are mixed, please remove and insert again" is displayed. Looking at the display, the depositor is 77 mm
If you remove the above banknotes and deposit them again, the optical sensor 24
After confirming that the banknotes of 77 mm or more are not included in the banknote bundle 11a, the banknote bundles 11a are fed into the transport path 23 one by one. The banknotes 11 conveyed one by one enter the banknote discrimination section 2a, and the watermark pattern detection sensor 13 shown in FIG.
Thus, the comparison with the watermark pattern stored in advance is performed, and thereby the denomination and the authenticity are determined. When the determination operation is completed, the bill validator 2a sends the bill to the temporary deposit safe 4. At the same time that all the banknote bundles 11a are stored in the temporary deposit safe 4, the display section 5 displays the discriminative amount of deposit, and after the depositor confirms this, the temporary deposit safe 4 to each safe deposit type A to D. It is sent to 6 and stored. On the other hand, as a result of the authenticity being discriminated by the watermark pattern detection sensor 13 in the bill discriminating unit 2a, the bills judged to be defective bills are once transferred from the bill discriminating unit 2a to the safe deposit box 3, and then the bill deposit / withdrawal is performed. Returned to mouth 1 and returned to the depositor.

Banknotes with a banknote height (shortest dimension) of 77 mm or more detected by the optical sensor 24 in the banknote deposit / withdrawal slot 1 are the old 10,000 yen bill and the old 5,000 yen bill. As shown in Fig. 6, the banknotes are also the first and second longest banknotes of all denominations (174 mm and 169 mm, respectively). As described above, due to the detection of the optical sensor 24, the old 10,000-yen bill and the old 5,000-yen bill are not conveyed in the conveyance path and the bill discriminating unit 2a. Therefore, the width W _{3 of the} transport path is 164 mm for the old 1,000-yen bill, 159 mm for the new 10,000-yen bill, and 154 mm for the new 5,000-yen bill, for example, the maximum value of the longitudinal dimension of the handling bills is 164 mm. It is recommended to set it to 174 mm, which is the sum of the meandering amount of 10 mm due to the transportation of. When a new 1000 yen bill with the smallest denomination to be handled is transported to this transport path, the permissible meandering amount is a value obtained by subtracting the length of the new 1000 yen bill from the transport path width W ₃ ,
That is, 174-150 = 24 [mm]. If the left and right displacement amounts are the same, there will be a 12 mm displacement on one side.

Therefore, the watermark pattern detection sensor 13 in the bill validator 2a
In advance, a watermark pattern is stored in advance for each 1 mm deviation in the range where the position deviation of the bill is 12 mm left and right. In this case, the number of watermark patterns that can be stored is only 24 for the New Thousand Yen bills. This is the discrimination unit 2 of the conventional device.
Compared to the 34 types of memory for a new 1,000-yen bill with a width of 184 mm, it can be reduced by 10.

As described above, in the present embodiment, the number of types of the pattern waveforms of the watermark portion stored for bill discrimination may be small, and it is not necessary to store the pattern of the unclear portion having a large misalignment, and hence the bills. The accuracy of true / false discrimination is improved.
Since the number of types of pattern waveforms to be stored may be small, the storage capacity can be small, and the processing speed for true / false determination can be increased. Also, since the old 10,000-yen bill and the old 5,000-yen bill are not taken into the transport path, it is possible to reduce the width of the transport path.
It is possible to reduce the size and cost of the device. Furthermore, since the size of the banknotes taken in is small, the inside size of various safes in the apparatus can also be made small.

In the present embodiment, the optical sensor 24 is used to detect the height dimension of the bill inserted from the bill deposit / withdrawal port 1, but a reflection type sensor may be used. Further, although the watermark pattern detection sensor 13 is provided in the bill discriminating unit 2a, the same effect can be obtained by using a sensor that optically or magnetically detects the amount of printing ink. Further, in the example, the height dimension detection amount of the bill is 77 mm, but the same effect is obtained when the dimension is from the short dimension of the new 10,000 yen bill to the short dimension of the old 5000 yen bill. Is obtained. In addition, a sensor for detecting the height dimension of the bill is used as the bill deposit / withdrawal port 1
However, a plurality of pairs may be provided.

〔The invention's effect〕

As described above, according to the present invention, since the banknote longitudinal dimension is limited to a predetermined value or less, the number of standard patterns of the watermark portion stored in advance in order to determine the denomination and authenticity of the banknote. The size of the device is small and the size of the transport path, the discriminating section, and various safes can be reduced, as well as the number of types and types can be reduced, the time required to distinguish between authenticity and denomination can be shortened, and the memory capacity can be reduced. And cost reduction can be realized.
