Description

DETAILED DESCRIPTION OF THE INVENTION (1) Technical Field of the Invention The present invention relates to a banknote validating device for validating banknotes in a money changer or the like.

(2) Prior Art and Problems Automatic currency exchange machines and automated teller machines have banknote validating devices for validating the banknotes used therein.

On the other hand, the banknotes used include many types of banknotes, such as national banknotes and old and new banknotes, and even banknotes of the same type include banknotes of multiple denominations.

Therefore, in a banknote validation device, the types of banknotes that it can identify are specified.For example, for each country's banknotes, separate banknote validation devices are prepared, and the types of banknotes that can be recognized by the banknote validation device are specified. It has become impossible to identify banknotes other than national banknotes.

Furthermore, even among banknote validating apparatuses that have the function of discriminating banknotes of the same type, there are apparatuses that can discriminate all denominations and apparatuses that have a function of discriminating only some denominations.

For this reason, automatic currency exchange machines and automatic cash transaction devices are provided for each type of banknote, and even if the banknotes are of the same type, there are cases where a banknote discrimination device is provided that can only distinguish among banknotes of some denominations. In order to be able to discriminate all denominations, it is necessary to replace the bill validating device with a corresponding function.

(3) Purpose of the Invention It is an object of the present invention to solve the above-mentioned conventional problems in a banknote validating device and to enable the validating of banknotes of many types and denominations.

(4) Structure of the Invention The above-mentioned objects include a detection unit that detects a pattern on a banknote according to the present invention, a discrimination unit that discriminates detected pattern data from the detection unit using discrimination pattern data;
A file that stores multiple identification pattern data,
A pattern memory that stores a smaller number of identification pattern data than the plurality of identification pattern data in a file, and controls storage of desired identification pattern data in the pattern memory by specifying desired identification pattern data from among the plurality of identification pattern data stored in the file. It has a control means, and after the control means stores desired discrimination pattern data from the file in the pattern memory, the bill to be discriminated is discriminated by the discrimination pattern data stored in the pattern memory. This is achieved by a bill validator.

File 7 in Figure 1
, M pieces of discrimination pattern data (P ₁ -P _n ) are prepared, and immediately after the power is turned on to the banknote validation device, the specified discrimination pattern data is taken out from the processor 8 and N pieces of pattern data are prepared. ( _F1 ～
F _o ).

Since M identification patterns (P ₁ to _{P n} ), which are extremely large in number compared to the number N of pattern memories, are prepared in the file 7, the contents (discrimination patterns) of pattern memories F ₁ to _{F o} are replaced. By this,
It is possible to handle the discrimination of many types of banknotes. Note that the control signals C ₁ -C _o given to the AND gates G ₁ -D _o in FIG. 1 are all "1" (therefore, the gates are open).

As mentioned above, due to the initial settings immediately after turning on the power,
required (N pieces of discrimination pattern data are selected,
The patterns are stored in pattern memories F ₁ to F _o .

After that, discrimination is started, and the banknote 1 inserted into the reading slot 2 is read by the detection unit 4, and the detection unit 4, which detects pattern data serving as identification data of the banknote, converts the analog signal to the digital signal. Since the pit extracting means is provided, the detection pattern data D of the digital signal is obtained as the output thereof, and this data D is stored in the detection pattern memory E. The discrimination unit 10 sequentially takes out discrimination pattern data (P ₁ -P _o ) from the pattern memory (F ₁ -F _o ), compares and collates the discrimination pattern data D in the detection pattern memory E, and discriminates the data. When the verification results match, the storage command A is issued from the discrimination section 10, so that the valve H of the switching gate section 5 is tilted to the left, and the banknote 1 is stored in the storage section 6. Further, if the verification results do not match, a discharge command is issued, so that the valve H is tilted to the right and the banknote 1 is discharged from the discharge port 3.

When the discrimination is completed, discrimination result data (type, number of sheets, amount, etc.) is stored in the memory 11. Note that by setting the signal level of the control signals C ₁ to _{C o} emitted from the control unit 9 to “0”, the AND gate G ₁
Since ~G _o can be closed, it is possible to arbitrarily control the outputs of the pattern memories F ₁ ~ _{F o} . Therefore, the discrimination pattern data (P ₁ to P _o ) can also be selected by this means.

FIG. 2 is a flowchart showing the processing procedure of the money exchange machine equipped with the banknote validating device shown in FIG.

In FIG. 2, immediately after the power is turned on, the attached I/O is initialized, and the money exchange machine enters a state in which it waits for a customer (ready for use). When the customer presses the transaction type (country) button on the exchange machine, the specified identification pattern data (P ₁ to _{P o} ) is retrieved from the file 7 shown in Figure 1 and stored in the pattern memory (F ₁ to F _o ).

Next, when you insert the banknote into the reading slot, the type of banknote,
After the amount is verified, the exchange amount is calculated and confirmed, the paid cash is counted, and the exchanged money is paid out from a cash payment section (not shown).

(6) Effects of the Invention As described above, the present invention only makes the discrimination pattern data variable, and since the detection section and discrimination section have functional versatility, it is possible to discriminate any type of banknote without requiring any particular changes. This system has the advantage that the type and number of automatic teller machines and the like can be reduced.
