CONSTITUTION:A CPU 31 controls each circuit device based on the programs stored in a ROM 32 and then stores and controls readably the control data into a RAM 33. Then the CPU 31 performs the ON/OFF control of a driving motor M of a genuineness deciding device 11 via an input/output device 34 and receives the read signals of a check 12 read by the magnetic heads 14 and 15. The CPU 31 stores and controls the transaction data on the check 12 including the serial number of the check 12, etc., in the RAM 33 for each transaction of the check 12. Then the CPU 31 collates the read serial number of the check 12 with the serial number of the check 12 stored in the RAM 33. Thus a forged check can be detected when a serial number equal to that used in a past transaction is decided.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a check authenticity determination device for reading transaction data recorded on a check to determine authenticity. More specifically, the present invention relates to not only the number of printed characters and the character shape but also the data content. The present invention relates to a genuine / counterfeit discriminating device for a check for discriminating genuine / counterfeit.

[0002]

2. Description of the Related Art Generally, a check authenticity discriminating apparatus reads a character printed on a check and discriminates whether the read character is a proper value by a check code or the like to discriminate the authenticity or the read character. The authenticity is determined by checking the individual verification.

However, when a check is authentically discriminated, if it is finely duplicated, a counterfeit check may be erroneously discriminated as a true check, and there is a problem of poor reliability.

[0004]

Therefore, the present invention focuses on the viewpoint of circulation and use of checks, and collates and confirms the transaction data of checks read at the time of transaction of checks and past transaction data already recorded and managed. Then, an object of the present invention is to provide a check authenticity determination device for determining the validity / invalidity of a check.

[0005]

SUMMARY OF THE INVENTION The present invention is a check authenticity determination device for determining authenticity based on reading transaction data recorded on a check, wherein all the transactions used for the above-mentioned transactions are dealt with. A storage means for storing data, and a check means for checking the transaction data of the read check and the stored data stored in the storage means at the time of reading the transaction data of the check are provided. Characterize.

[0006]

According to the present invention, the storage means stores and manages the transaction data of all checks used for transactions, and when the check transaction data is read, the read check transaction data and the storage means are stored and managed. The collation means collates the stored data in the past, and the authenticity of the check is determined based on the collation result. For example, at the time of transaction of a check, if the issue number of the check is an issue number already transacted, it is determined to be invalid as a duplicate counterfeit check.

[0007]

As described above, since all check data used for transactions are recorded and managed and collated and confirmed, if the same data as a check that has been traded in the past is immediately invalidated as a counterfeit check. Judgment can be made, and true / false judgment can be made accurately. Therefore, even if the counterfeit check is a finely copied copy, it is possible to determine the authenticity of the transaction data.
Highly reliable discrimination that eliminates erroneous discrimination can be performed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings. The drawing shows a check authenticity discriminating device internally configured in an automatic transaction machine. In FIG. 1, the check discriminating device 11 is a magnetic discriminating device for detecting a magnetic level at a leading end side of a conveying path 13 for conveying a check 12. A first magnetic head 14 is provided, a second magnetic head 15 for reading magnetic ink characters and a tacho generator 16 for character position detection are provided at the subsequent stage, and a check storage 17 is provided at the end. ing. In addition, a pair of upper and lower conveyor belts 18 constituting the conveyor path 13,
19 is driven by the conveyance motor M to nip and convey the check 12 guided therein at a constant speed.
After the print contents recorded in 2 are read by both magnetic heads 14 and 15, they are stored in the check storage unit 17.

The check 12 handled in this case is, for example, as shown in FIG. 2, a serial number, a bank number, a denomination number, which is printed at the time of manufacture, on a clear band 21 along one side edge of the check 12 in the reading direction. Pre-printed characters such as amount 22
Then, the encoded characters 23 such as a branch number and an account number printed at the time of issuance by a bank are recorded, and the authenticity is determined based on the data read by both magnetic heads 14 and 15.

FIG. 3 is a block diagram of a control circuit of the check / authentication check device 11, in which the CPU 31 controls each circuit device according to a program stored in the ROM 32, and the control data can be read out and stored in the RAM 33. To do. Further, the CPU 31 controls ON / OFF of the drive motor M of the authenticity determination device 11 via the input / output device 34, and also receives a check reading signal read by the magnetic heads 14 and 15.

In this case, the CPU 31 stores the transaction data of the read check, for example, the serial number of the check, in each check 12
Each time a transaction is used, the RAM 33 stores and manages the check 12
When the serial number of the check 12 is read, the serial number of the check 12 read is compared with the serial number of the check 12 stored in the RAM 33. Therefore, if the serial number is the same as the serial number that was traded in the past, it can be immediately identified as a duplicated counterfeit check.

As described above, since all serial number data of various checks used for transactions are recorded and managed, and the checks are traded while checking the past transaction data, the counterfeit checks are tentatively duplicated. Even if it is true or false,
Highly reliable discrimination is possible.

FIG. 4 shows the recorded contents per log which records the operation record when the transaction data of the check is stored and managed in the RAM 33. The sequence number is the log of the number of recognized characters at the time of reading the check, the log of the number of blank characters in the pre-printing section, Encoded print part recognition unknown character number log ... Counts up by one each time various log data such as log data is collected.

As for the log recording time, the value of the lower 3 bytes of the system lock when the log is taken is stored from the upper side, and M
As the ICR analysis result, the result read from the magnetic waveform of the recognized character is packed and 38 characters from the first character are stored in 19 bytes. The reserve stores the authenticity determination result.

Further, in managing the memory of the check 12,
Not only can one store and manage one transaction machine that handles transactions, it can also communicate with other automated transaction machines to manage data widely.

For example, as shown in FIG. 5, a communication control device is provided between the automatic transaction machines 52, ... Incorporating a check authenticity determination device having a control circuit 51 for storing and managing the check transaction data described above. Communication connection is made via 53. In this case, when the transaction data of the check is read, the transaction data of the read check and each automatic transaction machine 52 connected by communication ...
It is possible to immediately determine whether or not a check has a transaction in the past by collating it with the transaction data stored in.

Further, as shown in FIG. 6, each automatic transaction machine 62 ... Incorporating a check authenticity discriminating device having a control circuit 61 for storing and managing the transaction data of the checks described above is replaced by a high-order data management device. When the transaction data is stored and managed by communication connection with 63, the transaction data from each automatic transaction machine 62 ... Is collectively managed by this upper data management device 63, and each automatic transaction machine is managed from this. It is also possible to communicate the transaction data for each transaction of 62 ..., and to check the transaction data.

The processing operation of the check authenticity determination device 11 thus configured will be described with reference to the flowchart of FIG. Now, when a check 12 is inserted into an automated teller machine along with a check transaction operation, this inserted check 12 is checked.
Is introduced into the check authenticating device 11 and the transaction data of the check 12 to be traded therein is read (steps n1 to n2).

When reading the transaction data of this check 12,
The CPU 31 collates and confirms the read transaction data of the check 12 with the past transaction data stored and managed in the RAM 33, and determines whether the transaction data has already been transacted or new data based on the serial number for identifying the check and the like. Whether it is true or false is determined (steps n3 to n4).

At this time, if the check data is compared with the transaction data of the new check, it is judged as a proper check, the transaction of the check 12 is accepted, the check transaction is executed, and after the transaction is completed,
The specific transaction data relating to the check is stored in the RAM 33 to prepare for the next check transaction verification (step n).
5 to n6).

On the other hand, when it is determined that the read data is the same as the traded data, it is judged as a duplicated counterfeit check and treated as invalid, the check is rejected, and the rejected invalid data is rejected. Records are managed in the RAM 33 to prevent unauthorized use of counterfeit checks (step n7-
n8).

As described above, transaction data of all checks used for transactions are recorded and managed to be checked for verification. Therefore, in the case of the same data as a check that has been traded in the past, it can be immediately determined to be invalid as a counterfeit check. . Therefore, even if the counterfeit check is finely copied, it can be accurately discriminated as the counterfeit check based on the contents of the transaction data, erroneous discrimination can be eliminated and highly reliable discrimination can be made.

In the correspondence between the configuration of the present invention and the above-described embodiment, the storage means of the present invention is the RAM 33 of the embodiment.
Corresponding to the control circuit 51 of each automatic transaction machine 52 and the control circuit 61 of the higher-level data management device 63, and so on.
The matching means corresponds to the CPU 31, but the present invention is not limited to the configuration of the above-described embodiment.
