Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a banknote handling machine and a control method therefor, and more particularly to a banknote store such as a supermarket or a convenience store where received banknotes are stored and the stored banknotes are reused as change. The present invention relates to a banknote processing machine (change dispensing machine) that speeds up the process of depositing the received banknote into the banknote processing machine and a control method therefor.

[0002]

2. Description of the Related Art In recent years, a banknote processing machine (change dispenser) which is connected to a higher-level device of a POS (point of sale information) system at a supermarket or a convenience store and can reuse received bills as change has been developed. Introduced together with the processing machine.

[0003] Here, the banknote handling machine is generally a mechanism that mechanically takes in the inserted banknotes, stacks and stores them in a banknote storage, transmits the deposit information to an external host device, In response to a change dispensing request from the host device, the banknotes have the function of transmitting the deposit information of the stacked and stored banknotes and dispensing the corresponding amount of change.

[0004] The purpose of introducing such a banknote handling machine or coin handling machine is to automate the operation of paying out and storing money, to reduce the cash handling burden of a cashier in charge of a cash register, and to improve the efficiency of settlement operations. Raising, and combating miscalculation.

In a conventional banknote handling machine, in order to accurately grasp the number of sheets stored for each denomination, the banknotes are inserted one by one from an insertion slot, the banknotes determined to be genuine are stored, and the counterfeit banknotes are stored. The banknote determined is returned to the slot by reversing the transport device. Alternatively, a dedicated storage is provided inside the apparatus, or a switchable passage is provided between the insertion port and the dispensing port, and the medium (banknote) for which the counterfeit bill is determined is stored in the dedicated storage. And return it to the withdrawal port.

[0006] However, in a device of a type in which a banknote for which a counterfeit bill is determined is returned to the insertion slot, the storing operation is interrupted by the reverse rotation operation, and the efficiency is reduced. Further, an apparatus of a type including a dedicated storage box or a transfer path switching device requires such a storage space, and is not suitable for reducing the size of the entire apparatus.

[0007] On the other hand, in a business format such as a supermarket, a work flow in which a change is handed over to a customer and the received money is stored in a cash drawer (drawer) is generally performed in order to prevent trouble with the customer.

However, in this work flow, in order to store the received bills at the end of the work flow, it is confirmed that the cashier has accurately read the money received from the customer and stored all the money in the cash drawer. It is not possible.

To solve such a problem, a high-value bill key such as a "10000" key is provided as a cash register key.
The countermeasures are provided by strengthening the awareness so that there is no misunderstanding between the 5,000 yen note and the 10,000 yen note. However, if the cashier deliberately cheated, there is no way to confirm.

As a solution to this problem, a method of introducing a money handling machine, calculating the amount of money received by a machine (fixed payment), subtracting the sales amount, and releasing change (discharge of change) can be considered. It is actually operated at gas stations.

[0011]

However, at the cash register of a supermarket, although the number of shops introducing the above-mentioned banknote processing machine (change dispensing machine) has increased, if the machine calculates the deposit amount, the processing time becomes longer. This is contrary to the main purpose of introducing a change dispensing machine to a cash register in a supermarket to increase the processing speed, which is an obstacle to introducing a change dispensing machine.

Therefore, there is a demand for a small, inexpensive device capable of high-speed processing without changing the basic work flow of the operation mode. The present invention has been made in view of such a point, and is small, inexpensive, and capable of high-speed processing so that received banknotes can be collectively inserted, and is applicable to normal operation. It is an object to provide a banknote handling machine and a control method thereof.

[0013]

According to the present invention, in order to solve the above-mentioned problems, in a banknote handling machine for storing received banknotes and reusing the stored banknotes as change, the authenticity and denomination of the inserted banknotes are determined. A receipt discriminating unit for discriminating the bills, receiving and discriminating the bills from the receiving port, loading and storing the bills, and dispensing the loaded and stored bills from the payout port at the time of withdrawal,
When the deposit discriminating unit determines that the inserted banknote is a genuine note, an addition is performed for each denomination, and a money counter for each denomination that is subtracted at the time of dispensing, and a banknote that the deposit discriminating unit is inserted. And a value obtained by multiplying a predetermined coefficient by the number of unreadable cases stored in the cash counter and the number of unreadable cases stored in the unreadable number addition unit. A dispensable number counter that holds the sum of the dispensable number, a disbursement discriminating unit that discriminates a bill dispensed from the banknote storage at the time of dispensing, and the dispensing discriminating unit sets a value for dispensing. And a circulation path for guiding the banknote determined to be a banknote not to be received to the reception port of the banknote storage.

According to such a banknote handling machine, one banknote is processed.
When the money is received one by one, the number 1 is added to the money amount counter corresponding to the denomination determined by the money receiving determination unit, and the money is stored in the bill storage. When the depositing discrimination unit cannot discriminate because the banknotes are deposited as a bundle, each time, 1 is added to the illegible number adding unit, and the deposited banknotes are stored in the banknote storage similarly. You. Thus, since a deposit can be made, high-speed deposit processing can be performed, and no special mechanical means is required. Therefore, the apparatus is small and inexpensive, and is applicable to normal operation. .

Further, according to the present invention, a depositing discrimination unit for discriminating the authenticity and denomination of the inserted bill, a bill storage for loading and storing the bills which have been discriminated, and a bill dispensed from the bill storage. In a banknote processing machine provided with a withdrawal discriminating unit for discriminating a denomination of a banknote, in the control method of the banknote processing machine when the depositing discriminating unit discriminates the authenticity and the denomination of the banknote, When the inserted bill is determined to be a genuine bill, the bill is stored in the bill storage as a genuine bill and added to the money amount of the determined denomination, and when it is determined to be a fake bill,
There is provided a control method for a banknote processing machine, wherein a banknote that is added as an unreadable number and a banknote determined to be a counterfeit note is stored in a banknote storage as it is.

According to such a control method of the banknote handling machine, since the banknotes to be deposited are confirmed to be genuine in the cashier, all the banknotes are stored irrespective of the discrimination result by the depositing discrimination section. To be stored. However, when the depositing discrimination unit cannot discriminate, the fact that there is no discrimination is stored as the number of non-discriminating cases. As a result, a numerical value obtained by multiplying the number of unreadable cases by a predetermined coefficient can be converted into a storage number of a predetermined denomination, and can be used as a payable number at the time of payment. Since the banknote that cannot be distinguished is not returned, the deposit processing can be performed at high speed.

[0017]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, an embodiment of the present invention
A case where the present invention is applied to a banknote handling machine for a supermarket or a convenience store used as an OS terminal will be described in detail with reference to the drawings.

FIG. 1 is a view showing the external appearance of the banknote handling machine, and FIG. 2 is a side sectional view showing the internal structure of the banknote handling machine. In these figures, the banknote handling machine 1 is, in appearance, an input port 2 for depositing banknotes, a dispensing port 3 from which banknotes are dispensed as change from the banknote processing machine 1, and a high price not used as change. A bill collection box 4 for storing bills (10,000 yen) is provided.

In the vicinity of the bill insertion slot 2, a deposit discriminating section 5 is provided.
Is provided, and there is a bill receiving port 7 of the bill storage vault 6 ahead. At the lower part of the banknote storage 6, there is provided a feeding unit 8 for separating and feeding the stacked and stored banknotes one by one from below. A dispensing determination unit 9 is provided downstream of the payout port of the bill storage 6 from which bills are fed. The payout port of the banknote storage 6 is the dispensing port 3 and the circulation passage 1 arranged vertically.
Connected to 0. The lower end of the circulation passage 10 is provided with a switching gate 11 for switching the bill conveyance path, and the upper end is connected to the bill receiving port 7. The circulation passage 10
A switching gate 12 for switching the transport path to the bill collection box 4. Here, the dispensing port 3, the bill collection box 4, the bill storage box 6, and the circulation passage 10 are integrated to form an internal unit, and the internal unit is housed in the housing 13 in a drawable state. .

Here, the operation of the banknote handling machine 1 during a normal transaction will be described. First, when a bill is inserted through the insertion slot 2, the insertion of a bill is detected by a not-shown insertion detection sensor, and a not-shown insertion conveyance motor is driven.
The bill is guided to the deposit determination unit 5, where the denomination and the authenticity are determined. Here, when the operation mode is set to the normal mode, as a result of the discrimination of the denomination and the determination of the authenticity, the banknote for which the deposit discrimination sensor 5 cannot be determined to be a genuine bill (genuine) is inserted. Returned to 2. If the deposit determination sensor 5 cannot determine that the bill is genuine when the illegible ticket storage mode is set,
It is determined that the bundle has been received, and the storing operation is continued without being returned.

That is, since the insertion slot 2 allows a bundle of a plurality of bills to be deposited, one or more bills pass through the deposit judging section 5. When one bill is inserted, the deposit determination unit 5 can determine the denomination and authenticity of the inserted bill. However, in the case of a deposit, the deposit discriminating section 5 cannot determine the denomination, so that the discrimination becomes impossible, and it is determined that there is a deposit. The banknotes discriminated by the deposit discrimination unit 5 are guided to the banknote storage 6 through the banknote receiving slot 7 and are stacked and stored in the banknote storage 6.

The stored banknotes are issued when there is a change payout command from a higher-level control device (not shown) or when a payout operation is performed on an operation / display unit (not shown).
Banknotes are fed one by one from below the banknote storage 6 by the feeding unit 8, and the denomination determining unit 9 determines the denomination. Here, if it is determined that the bill should be dispensed, the switching gate 1
1 is switched to the dispensing port side, and the bill is guided to the dispensing port 3. If the fed-out banknote is determined to be a banknote that should not be dispensed or an unreadable banknote, the switching gate 1
1 is switched to the circulation passage side, and is stacked and stored in the bill storage 6 again via the circulation passage 10. In the case where the fed banknote is a high-value banknote that is not used as change, the switching gate 12 is switched to the banknote collection box side,
The large bill is stored in the bill collection box 4.

Next, the configuration of the control unit of the bill processing machine 1 will be described. FIG. 3 is a block diagram illustrating a configuration example of a control unit of the banknote handling machine. The control unit 20 of the banknote handling machine 1 includes:
Payment determination sensor 21 and payment determination unit 9 of the payment determination unit 5
A denomination determination unit 23 connected to the withdrawal determination sensor 22 of
A processor (CPU) 24 and an internal memory 25
A transport control unit 27 that controls and drives the transport motor 26;
A mode determination unit 28, a monitoring timer 29, and a transmission unit 30 are provided. The in-appliance cash memory 25 includes a 1,000-yen counter 25a, a 5,000-yen counter 25b, and a 10,000-yen counter 25c, which are counters for the denominations handled.
And a counter 25d for the number of unreadable at the time of payment and a storage number counter 25e for judging a dispensable state. The transmission unit 30 is connected to the host device 31.

When the processor 24 receives a bill insertion detection from a not-shown insertion detection sensor provided near the insertion slot 2 or when a change payout command is issued from the host device 31, Control is performed to start the transport motor 26. The denomination determining unit 23 has a function of determining three denominations of a circulating bill. This denomination discriminator 2
Numeral 3 discriminates the denomination of the bill detected by the deposit discrimination sensor 21 at the time of deposit, and sends the discrimination result to the processor 24. The processor 24 receives the result of the determination, and stores the internal memory 2 in the apparatus.
The value is sent to the counter of the corresponding denomination of 5, and +1 is added. The denomination discriminating unit 23 also discriminates the denomination when the dispensing discrimination sensor 22 detects the banknote fed from the banknote storage 6, and sends the denomination to the processor 24. The processor 24 sends the discrimination result to the in-apparatus balance memory 25, and subtracts -1 from the counter of the corresponding denomination. As a result, the number of banknotes deposited and withdrawn through the insertion slot 2 and the dispensing slot 3 is managed in the internal high memory 25 in the apparatus. However, when the depositing discrimination sensor 21 cannot discriminate the deposited banknote due to a bundle deposit at the time of depositing,
Each time, +1 is added to the counter 25d for the number of unreadable when payment is made. In addition, the withdrawal state determination storage number counter 25e of the in-device cash memory 25 is a withdrawal that the processor 24 refers to the value of another counter in the in-device cash memory 25 and is estimated to be in the device. The possible number is calculated and stored. The mode determination unit determines the set operation mode, and the processor 24 performs processing according to the determined operation mode. The monitoring timer 29 waits for a predetermined amount of time and waits for a large bill to be received in response to a pressing operation of a “10000” key of an operation / display unit (not shown) operated when the currency received from the customer includes a ten thousand yen bill. It is for doing.

Although not shown, the control unit 20 drives the transport motor 26 in response to various detection sensors, starts / stops the feeding unit 8, switches the switching gate 11,
Twelve switching controls can also be performed.

Next, the deposit / withdrawal processing of the banknote handling machine 1 will be described. FIG. 4 is a flowchart showing the flow of the normal deposit processing. First, when a bill is inserted into the insertion slot 2 when the operation mode is set to the normal mode through an operation / display unit (not shown), an insertion detection sensor (not shown) detects the bill (step S1). Notify that. Then, the control unit 20 drives the transport unit including the transport motor 26 via the transport control unit 27, and starts taking in bills (step S2). The captured banknotes
When the money reaches the deposit judging unit 5, the deposit judging unit 5 discriminates the deposit, and judges the denomination from the characteristics of the bill (step S).
3). Next, it is determined whether the discrimination result is a genuine bill (step S4). As a result of the discrimination, when the bill is a genuine bill, the bill is added to a counter corresponding to the denomination in the in-stored amount memory 25 (step S5), and the bill is stored in the bill storage 6
After transport and storage, the transport unit is stopped (step S6).

If the discrimination result is a counterfeit note (meaning that it is not one genuine note), the transport unit is stopped (step S).
7), the transport unit is driven to rotate in the reverse direction, and the bill is returned to the slot (step S8). Then, the transport unit is stopped (step S9), and the process waits for the insertion of bills.

FIG. 5 is a flowchart showing the flow of the conversion permission deposit processing. When the operation mode is set to the unreadable ticket storage mode / storage number conversion mode through an operation / display unit (not shown), first, when a bill is inserted into the insertion slot 2, a not-shown insertion detection sensor detects the bill. (Step S11), the control unit 20 drives the transport unit (Step S12). The received banknote is subjected to payment discrimination by the payment discrimination unit 5 (step S13). next,
It is determined whether the discrimination result is a genuine bill (step S1).
4). As a result of the discrimination, when the bill is a genuine bill, the bill is added to the counter corresponding to the denomination in the in-stored amount memory 25 (step S15), and the bill is transported to the bill storage 6 and stored therein. Stop the transport unit (Step S1
6).

If the discrimination result is a counterfeit note (meaning that it is not one genuine note), the mode determining section 28 in the control section 20 determines the operation mode, and the processor 24 No stop request is issued to
Store in storage. At this time, the internal storage memory 25
Then, "1" of the number of illegible cases is added to the counter 25d of illegible cases upon payment (step S17). Then, a money amount conversion process is performed to update the number-of-payable state determination storage number counter 25e in the money amount memory 25 in the apparatus (step S18). This money amount conversion process is performed according to the following equation 1.

[0030]

## EQU00001 ## The number of stored sheets for withdrawal possible state determination = the number of thousand yen determinations + K.times.number of undeterminable cases (1) Here, K is a coefficient, the details of which will be described later. As a result, the value of the number of thousand-yen banknotes that are considered to be dispensable is stored in the dispensable state determination storage number counter 25e.

FIG. 6 is a flowchart showing the flow of the dispensing process. When paying a bill as change, first, the processor 24 refers to the withdrawal state determination storage number counter 25e, the 5,000 yen number counter 25b, and the 10,000 yen number counter 25c in the internal cash amount memory 25. Then, it is determined whether it is possible to withdraw money, that is, whether or not the money amount constituting the amount indicated as change exists in the apparatus (step S21). Here, if there is no money and it is impossible to withdraw money, the process ends abnormally. If the withdrawal is possible, the feeding unit 8 is driven to feed one banknote from the banknote storage 6 (step S22). Next, the dispensing determination unit 9 discriminates the fed bill (step S23). Here, it is determined whether or not the bill is a denomination corresponding to withdrawal as a part of the change (step S24). If the bill fed from the bill storage 6 is not the corresponding denomination, or if the denomination discrimination unit 9 cannot determine the denomination, the switching gate 11 is switched to the circulation passage 10 to switch the bill. Storage 6
(Step S25). At this time, if the withdrawal discrimination result by the withdrawal determination unit 9 is a denomination (10,000 yen) that is not reused for change, the switching gate 1 in the middle of the circulation passage 10
2 is switched to the banknote collection box 4 side, and the banknotes fed from the banknote storage box 6 are collected in the banknote collection box 4.

If it is determined in step S24 that the denomination is worth a withdrawal, the switching gate 11 is switched to the withdrawal port 3 to perform the withdrawal (step S26).
Next, the counter of the corresponding denomination and the stored number counter 25e for dispensable state determination in the internal cash amount memory 25 are set to 1
Is subtracted, and the remaining amount in the apparatus is subtracted (step S2).
7). The processing from step S22 to step S27 described above is performed until the withdrawal reaches the amount indicated as change. When the withdrawal reaches the instructed amount, the bill collection box 4
Is completed (step S28), and the feeding unit 8 is stopped (step S29).

Here, the result of examining the number of denominations paid by banknotes among the money paid by the customer at a cash register of a supermarket is shown below. FIG. 7 is a diagram showing an example of a payment pattern by a customer's bill. According to a typical bill payment pattern at a supermarket cash register, about 70% of the total number of payments is 10,000 yen1.
One piece, one 5,000 yen, or one thousand yen. The other is a combination of a plurality of bills. As shown by the dashed line in FIG. 7, focusing on the combination of a plurality of sheets, two thousand yen are about 50% of the whole, and a plurality of 1,000 yen is more than 90% of the whole. You can see that there is. From these points, Equation 2 is obtained as a stored number conversion equation.

[0034]

[Equation 2] Thousand-yen-converted storage number (amount of money) = 1000 yen-amount of money + K × number of illegible cases (2) Here, when the coefficient K is varied and the converted value is simulated, it is as follows. become.

FIG. 8 is a diagram showing the relationship between the actual number of stored 1,000-yen banknotes and the converted value. From FIG. 8, the actual number of stored 1,000-yen banknotes is 311. On the other hand, the coefficient K of 2, 2.5, and 3 is added to the number of illegible cases (number of payments of a plurality of sheets).
Is multiplied by 1000 and the number of judgments is 245, 289
And 344 sheets. From the results of this simulation, it can be seen that K = 2.7 is the optimum value for the conversion of the actual number of sheets stored, and that about 80% can be reproduced in actual operation when K = 2.

Next, a description will be given of a work flow of a cash register such as a supermarket or a convenience store. FIG. 9 is a diagram showing an example of a typical cash register work flow. According to FIG. 9, first, the cashier registers the price of the purchased product brought by the customer to the cash register. In recent years, the registration of this product is performed by performing a barcode scan using a POS scanner. Then, the total price of the registered merchandise is calculated at the POS, and the total purchase price is presented to the customer.

[0037] The customer pays the purchase amount or slightly more. At this time, the paid money is put on a depositing dish (also called a scholar stand) and held. Then, the received amount is calculated from the several kinds of money groups and registered in the POS keyboard. At this time, if the received money contains a 10,000-yen bill, the user presses the "10000" key provided on the POS keyboard so that the user can be conscious of not making a mistake with 5,000 yen.

At the timing of the above-mentioned product registration, the PO
The S terminal sends out a withdrawal command to the change machine. The change machine configures the amount of money for each denomination in response to the instruction and releases the change. Then, the cashier gives the change and the receipt to the customer. If the customer approves, the customer receives it and the cashier greets, thereby completing the transaction with the customer.

Thereafter, the money held in the storage tray is put into a change machine (a banknote handling machine / coin handling machine), all the processing is completed, and the processing proceeds to the next customer. Here, the POS side (upper-level device) and the banknote processing machine (change machine) operate as follows in order to eliminate registration errors of high-value banknotes.

FIG. 10 is a time chart showing the operation at the time of confirming payment of a large bill. First, the POS side (upper device)
When the "10000" key is pressed, after the dispensing instruction command is transmitted, the completion of dispensing of the bill processing machine is confirmed. After that, the POS terminal sends a high-value bill payment waiting command to the bill processing machine. In response to this, the banknote handling machine starts the monitoring timer 29, and enters a state of waiting for a large bill. The cashier will give the released change and receipt to the customer in accordance with the work flow of the cash register.

The customer receives the change of the same amount as predicted by the customer as it is. The cashier gives a thank-you greeting and completes the transaction. Assuming that the cashier has accepted the transaction, the cashier puts the received coin into the coin slot, and puts the bill into the slot of the bill processing machine.

The bill processing machine determines the denomination of the deposited bill by the deposit determining section 5. If it is other than 10,000 yen, the amount of money is added, and then loaded and stored in the storage. When the deposited bill is 10,000 yen, the processor 24 of the control unit 20 sets an affirmative response in the transmission unit 30.

At the same time, the control unit 20 cancels the state of waiting for payment of a large bill. When this is viewed from the POS side, it means that the state of the banknote handling machine is monitored (by the large banknote payment confirmation command) at regular intervals after the banknote handling machine is in a state of waiting for a high-value banknote deposit. Before the payment of 10,000 yen, a busy response is returned by the transmission unit 30. Then, after the payment of 10,000 yen is confirmed, when a high-value banknote payment confirmation command is given, a positive response prepared in the transmission unit 30 of the banknote processing machine is returned to the POS.
The POS can confirm the payment of 10,000 yen. In addition, when there is no affirmative response in response to the payment of 10,000 yen, the high-amount bill waiting state is released by the time-out of the monitoring timer 29. In addition, since this is intended to make the user aware of the handling of high-value bills, even if there is no payment of 10,000 yen before the time-out of the monitoring timer 29, the transmission unit 30 only returns a negative response. It does not perform any processing such as making a sound.

FIG. 11 is a time chart showing another operation at the time of confirming payment of a large bill. First, when the "10000" key is pressed, the POS side (upper device) confirms the completion of dispensing of the bill processing machine after transmitting the dispensing instruction command. At the same time, the banknote handling machine is in a state of waiting for a large bill. The cashier gives the released change and receipt to the customer according to the work flow of the cash register.

The customer receives the change of the same amount as predicted by the customer as it is. The cashier gives a thank-you greeting and completes the transaction. Assuming that the cashier has accepted the transaction, the cashier puts the received coin into the coin slot, and puts the bill into the slot of the bill processing machine.

In the meantime, the POS periodically issues a high-value banknote deposit confirmation command to the banknote handling machine.
Until 0000 yen is received, the banknote handling machine returns a busy response. The banknote handling machine determines the denomination of the deposited banknotes in the depositing discriminating unit 5, and if it is other than 10,000 yen, adds the amount of money and loads and stores it in the storage. When the deposited banknote is 10,000 yen, the control unit 20 sets an affirmative response in the transmission unit 30 and cancels the state of waiting for a high-value banknote payment. The state of waiting for the payment of the large bill is 100
If there is no affirmative response in response to the deposit of 00 yen, it is canceled by issuing the next withdrawal command.

[0047]

As described above, according to the present invention, when the inserted bill is judged to be a genuine bill, it is stored as a genuine bill in the bill storage, and is added to the amount of money of each denomination. When it is determined that the bill is counterfeit, the number of illegible cases is added and stored in the bill storage. This makes it possible to configure a banknote handling machine capable of performing a high-speed deposit processing without any mechanical addition, and is applicable to normal operation.

Also, with a simple command and sequence,
This makes it possible to confirm the payment of large bills, thereby reducing the processing efficiency of the cash register and improving the morale of the person in charge of the cash register.
