Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic teller machine (hereinafter also referred to as "ATM") at the time of a withdrawal transaction. 2. Description of the Related Art Conventional ATM (Automatic T)
In the case of dispensing banknotes or the like, in order to process banknotes stored in the recycle box as genuine bills, the banknotes are dispensed without discriminating the banknotes. FIG. 3 is a block diagram of a main part of a conventional ATM handling bills. The conventional ATM includes a deposit / withdrawal unit 10 serving as a mouth for depositing and dispensing banknotes, a cassette 11 used for loading the banknotes into the ATM, a discriminating unit 12 for discriminating the banknotes, and dispensing after discriminating. A recycle box 13 for storing banknotes to be used for reconciliation, and a reject box 14 for storing banknotes that are not genuine bills (real banknotes) after being discriminated, or that are genuine but are torn or dirty and cannot be used for dispensing. , And a transport path that enables the movement of bills between these blocks. The arrow shown in the transport path indicates the transport direction of the bill. [0005] Generally, the functions of handling banknotes at the ATM include "loading" in which banknotes or security workers store banknotes from outside the ATM, "payment" in which the customer deposits in their own accounts, and "Withdrawal" that withdraws banknotes from the account,
There are "transfer" to remit to another person's account, "payment" to calculate the bill inside the ATM, etc. Here, "load", "payment",
"Payment" will be described below with reference to FIG. [0006] In the ATM shown in FIG. 3, in the case of “loading”, bills are set in a cassette 11 by a bank clerk or the like, moved along a transport path, sent to a discriminating section 12, and after being discriminated by the discriminating section 12. , Recycling box 13
Alternatively, it is stored in the reject box 14. "Deposit"
In the case of, the banknote deposited by the customer is transported from the depositing / dispensing unit 10 to the discriminating unit 12, and after being discriminated by the discriminating unit 12, the recycle box 13 or the reject box 14
Or if it is determined that the ticket is not genuine, it is returned to the customer. Attach bills to ATMs like "loading" and "depositing"
When stored in the recycle box 13 from outside to inside, the bill stored in the recycle box 13 is a genuine bill once discriminated. Therefore,
In the conventional ATM, in the case of "withdrawal", it was thought that it was not necessary to discriminate the bill again, so the bill was conveyed to the discriminating unit 12, but was conveyed to the deposit and withdrawal unit 10 without discrimination, and Corresponding to the drawer. [0007] In the prior art described above, when maintaining an ATM, maintenance personnel do not use genuine bills,
Maintenance and inspection are often performed using simulated banknotes (non-genuine banknotes). At this time, the ATM has a "genuine note mode" and a "simulated note mode". In the latter case, the discriminating section 12 does not perform discrimination of the simulated banknotes and the simulated banknotes are accurately conveyed along the conveyance path. A transport test is performed to determine whether or not the banknote is simulated. After executing the transport test, the maintenance staff removes the simulated banknotes stored in the recycle box 13 and ends the maintenance, but stores the simulated banknotes in the recycle box 13 due to a human error (for example, the maintenance staff forgets to remove them). It is also conceivable to end the maintenance while keeping the state. When such a situation occurs, the conventional ATM dispenses the simulated banknotes left in the recycle box 13 as genuine bills even at the time of “dispensing” as described above, which causes serious inconvenience to customers. In addition, there was a problem that the trust of the financial institution was greatly lost. An object of the present invention is to solve the above-mentioned problems of the prior art and to provide a cash processing apparatus capable of executing bill discrimination at the time of dispensing. In order to achieve the above object, according to the present invention, as a constituent element of a cash processing apparatus, a cash-receipt-and-disbursement unit in which a customer trades bills, and a bill conveyed from a cash-receipt-and-disbursement unit. A discriminator for discriminating bills, and a first box (recycle box) for storing bills discriminated as genuine bills by the discriminator
And a second box (reject box) for storing banknotes that cannot be dispensed to the customer by the discriminating unit, and a banknote connected to the discriminating unit via a signal line and taken out of the first box in which a genuine note is stored Is transferred to the discriminating unit, and when the banknote is discriminated by the discriminating unit, the banknote is discriminated more easily than discrimination at the time of deposit.
And a control unit for instructing discrimination by the discrimination program . According to the cash processing apparatus of the present invention, the discriminating section discriminates a bill conveyed from the first box in accordance with an instruction signal from the control section, and the discrimination result by the discriminating section is determined to be a genuine bill. When the discrimination unit determines that the bill cannot be dispensed to the customer, the bill is conveyed to the second box. An embodiment of a cash processing apparatus according to the present invention will be described below in detail with reference to the drawings. FIG. 1 shows a block configuration of an embodiment of the cash processing apparatus of the present invention. However, the same numbers are assigned to blocks having the same functions as those in FIG. First, the first embodiment will be described in detail. Now, when a customer or the like deposits a bill from the depositing / dispensing section 10, the bill is conveyed from the depositing / dispensing section 10 to the discriminating section 22 via a transport path, and the bill is discriminated by the discriminating section 22. When a maintenance person or the like sets a large amount of bills in the cassette 11, the bills are conveyed from the cassette 11 to the discriminating unit 22 via the conveying path, and the bills are discriminated by the discriminating unit 22. Next, the bills thus discriminated by the discriminating unit 22 are placed in the recycle box 13, which is the first box, when the bill is a genuine note, according to the discrimination result.
If the bill is not genuine (including torn or dirty), it is returned to the customer if it is a deposit transaction, and the second box if it is loaded or withdrawn. In the reject box 14 via the transport path. Subsequently, when a customer or the like withdraws a desired banknote from the depositing / dispensing unit 10, that is, at the time of the above-mentioned “dispensing”, an instruction signal relating to processing from the customer is output to the control unit 20, and the control unit 20 is controlled. 20 takes out a desired bill from the recycle box 13 in which the genuine bill is stored, and outputs an instruction to transport the bill to the discriminating unit 22 via the transport path. The bills conveyed to the discriminating unit 22 are discriminated by an instruction from the control unit 20, and only the bills determined to be genuine are discriminated by the discriminating unit 22.
Are conveyed to the deposit / withdrawal unit 10 via the conveyance path, and the banknotes that cannot be determined as genuine bills are conveyed from the discrimination unit 22 to the reject box 14. As described above, the customer can withdraw a desired bill (only genuine bill) from the depositing / dispensing section 10 by a special discriminating process of the cash processing apparatus according to the present invention which has not been conventionally provided. . Further, according to the present embodiment, even if articles other than genuine bills are mixed in the recycle box 13, it can be rejected to the reject box 14 at the time of “withdrawal”. Next, a second embodiment will be described in detail with reference to FIGS. 1 and 2. The second embodiment is different from the above-described first embodiment in the time of dispensing banknotes. Can be executed in a shorter time, which is sufficiently effective for a financial institution that positions reduction of transaction time as one of customer services. As shown in FIG. 1, a control unit 20 and a memory 21 are connected to each other via a signal line from a discrimination unit 22, and a normal discrimination program and a simple discrimination program for withdrawal transactions are stored in the memory 21. Store. The control unit 20 determines whether or not the current transaction is “withdrawal”. If the current transaction is “withdrawal”, the simple identification program is extracted from the memory 21. Loading to the discrimination unit 22. Here, the normal discrimination program and the simple discrimination program will be described. The normal program is an execution program for discriminating banknotes by the discriminating unit 22 at the time of “payment”, “loading”, and the like. On the other hand, the simple discrimination program is an execution program in which the discrimination unit 22 discriminates a bill at the time of "withdrawal", and the simple discrimination program has a lower degree of discrimination of a banknote than a normal discrimination program, and the discrimination processing time is thereby reduced. The feature is that it is also fast. FIG. 2 shows a processing flow relating to discrimination switching of the control unit 20 in FIG. First, the control unit 20 determines whether or not the current transaction is “withdrawal” (step 301). If the control unit 20 determines that the current transaction is not “withdrawal”, the control unit 20 compares the normal discrimination program in the memory 21 with the discrimination unit 22.
(Step 302), and when it is determined to be "payment", the simple discrimination program in the memory 21 is loaded to the discrimination unit 22 (Step 303). As described above, the control unit 20 executes the predetermined discrimination program on the discrimination unit 2
2, the discrimination switching is performed, and the loaded discrimination unit 22 executes a transaction using a predetermined discrimination program. In the present embodiment, two types of discrimination programs are stored in the memory 21 and the control unit 20 causes the discrimination unit 2 to execute each transaction.
However, if the discrimination unit 22 has a sufficient capacity of memory, two types of discrimination programs are resident in the discrimination unit 22, and the control unit 20 executes the program required for each transaction. May be started. Thus, there is no need to prepare the memory 21, and there is also an effect that the cash processing device can be downsized. Here, the simple discrimination program stored in the memory 21 of FIG. 1 will be described in detail. Generally, in an ATM, a normal discriminating program scans a banknote with a magnetic sensor, an optical sensor, or the like, performs various operations with a plurality of algorithms, and finally performs a logical operation such as a logical product operation to denomination (10,000). Yen, 5,000 yen, 1,000 yen) and authenticity. At the time of "loading" and "payment", the discrimination program rejects counterfeit, falsified bills and the like that are not genuine bills. On the other hand, the object of the present invention is to reject the simulated banknotes slipped into the recycle box 13 at the time of maintenance and inspection, so that the accuracy is not required as much as the normal discriminating program. Further, if the same discrimination program is executed at the time of withdrawal, there is a problem that the transaction time becomes longer and the possibility of rejecting a genuine bill increases. Therefore, at the time of withdrawal, an algorithm that rejects only the simulated banknote and has a short processing time is more suitable. The following formula is used as the basis of this algorithm. ## EQU1 ## Here, S (i) is the output value of the aforementioned sensor. In addition, i indicates the address of the sensor output, and here, it is assumed that an address value from i = 0 to A is taken. Thus, f means the sum of S (a) to S (b) in the middle of the sensor output values S (0) to S (A). Therefore, in the simple discrimination program, if f is equal to or more than a certain value, it is determined that the ticket is genuine. As described above, the normal discriminating program uses a plurality of sensor output values and uses addresses from i = 0 to A, whereas the simple discriminating program scans only a small part of the bill (for example, from the end of the bill). The sum of the sensor output values from 2 to 3 cm) is determined only to determine whether the bill is genuine. This utilizes the characteristics of a banknote that it contains magnetism or reacts to an optical sensor of a specific color to obtain a higher output than a simulated banknote. In addition, the above equation may be a software operation, or any value that can be obtained in hardware may be used. As described in the second embodiment, the normal discriminating program and the simple discriminating program are stored in the memory 21 and the control unit 20 switches between the programs. Compared to the example,
In addition, it is possible to discriminate whether it is a “genuine bill” or not in a short time. According to the cash processing apparatus of the present invention, when a customer or the like dispenses bills, the processing time for discrimination can be shortened, and genuine bills can be reliably provided.
