Hereinafter, the operation and effect of the banknote counting apparatus according to the embodiment of the present invention will be described in connection with the banknote counting apparatus according to the embodiment of the present invention configured as described above.

In Fig. 3, S denotes a step.

As an initial condition for operation description, it is assumed that the power switch 22 is turned on, so that an AC voltage of 220 V is supplied from the external AC power supply 20 to the DC voltage supply circuit 18. Therefore, a DC voltage of 5V is output from the output terminal VDD of the DC voltage supply circuit 18 to the winding type identification and control means 16, and from the output terminal WC of the DC voltage supply circuit 18. It is assumed that a 24V DC voltage is output to the first motor drive circuit 38 and the second motor drive circuit 44 via the winding identification and control means 16.

First, in the banknote loading step S1, the user arranges the banknotes to be counted on the first banknote support 8. At this time, the wide side of the banknote is in contact with the bottom surface of the first banknote support (8). The bills are then loaded. A position signal is then output from the first position detection sensor 28 to the roll identification and control means 16 indicating that the bill is loaded at the loading position.

Subsequently, a control signal is output from the winding type identification and control means 16 to the first motor drive circuit 38 and the second motor drive circuit 44 in the banknote movement step S2.

Then, a voltage is applied from the first motor driving circuit 38 to the main motor 36 to rotate the main motor 36. Subsequently, a voltage is applied from the second motor drive circuit 44 to the transport motor 42 so that the transport motor 42 rotates.

By mechanical means, not shown, as the main motor 36 rotates, the bottommost banknote in the loading position is pulled out so that the banknote is moved to the color sensing and counting position in the housing 4. Move.

In the next color sensing step S3, the color sensing means 14 detects the color of the bill at the color sensing and counting position. Subsequently, a color signal is output from the color detecting means 14 to the paper type identification and control means 16.

Next, in the first paper type discrimination step S4, the paper type identification and control means 16 stores the color data corresponding to each paper type of the paper money stored in the memory 12 and the geology and luminance of the paper money in the color detecting means 14. The color detection signals of the color distribution map and the color patch are compared. Then, the paper type identification and control means 16 determines whether the paper money is the first paper type. The first roll is, for example, 10,000 won rolls. If it is determined that the banknote is the first kind, as a result of the discrimination, the process proceeds to the reference kind memory storing step S5 (if YES).

In the reference winding type storage step S5, data of the first winding type is output from the winding type identification and control means 16 to the memory 12. Then, the first roll of paper is stored in the memory 12 as a reference roll.

Subsequently, in the count increasing step S6, a count signal is output from the coefficient detecting means 26 to the winding type identification and control means 16. The paper type identification and control means 16 then increments a count that represents the number of bills allocated to the memory 12 by one. Subsequently, in the count display step S7, a display signal is output from the winding type identification and control means 16 to the display means 2. The display means 2 then displays the number of bills. For example, the indication is "1".

The bill is then identified and counted is conveyed to the release position of the second bill support 10 by mechanical conveying means, not shown, connected to the transport motor 42.

When the bill is transported to the second paper support 10 and placed on the second bill support 10, a position signal is output from the second position detection sensor 30 to the winding type identification and control means 16. . The winding type identification and control means 16 then recognizes that the bill is released to the release position of the two bill holders 10.

Subsequently, in the remaining banknote discrimination step S8, the denomination type identification and control means 16 determines whether the position signal has been input from the first position detection sensor 28 to the denomination type identification and control means 16, thereby supporting the first banknote support. In (8), it is determined whether there are any bills to be counted. As a result of this determination, when it is determined that there is no banknote to be counted on the first banknote holder 8, the banknote counting operation is finished because all banknotes are counted (in the case of NO).

On the other hand, when the paper type identification and control means 16 determines that the banknote is not the first paper type in the first paper type determining step S4 (if NO), the flow advances to the second paper type determining step S9.

In the second book type discrimination step S9, the book type identification and control means 16 determines whether the bill is the second book type. The second kind is, for example, 5,000 won. As a result of the discrimination, if it is determined that the banknote is the second kind, (YES), the processing goes to the reference kind memory storing step S5.

In the reference winding type storage step S5, data of the second winding type is output from the winding type identification and control means 16 to the memory 12. Then, the second roll type is stored in the memory 12 as the reference roll type.

On the other hand, when the paper type identification and control means 16 determines that the paper is not the second paper type in the second paper type determination step S9 (if NO), the flow advances to the third paper type determination step S10.

In the third kind determination step S10, the kind identification and control means 16 determines whether the bill is a third kind. The third kind is, for example, 1,000 won winding. As a result of this determination, in the case where it is determined that the banknote is the third kind, (YES), the processing goes to the reference kind storage step S5.

In the reference winding type storage step S5, data of the third winding type is output from the winding type identification and control means 16 to the memory 12. Then, the third roll type is stored in the memory 12 as the reference roll type.

On the other hand, when the book type identification and control means 16 determines that the bill is not the third book type in the third book type determining step S10 (when NO), the bill is stored in the memory 12 in the normal book type. Since it does not correspond to the banknote of, it proceeds to error display step S11.

In the error display step S11, a display signal is output from the paper type identification and control means 16 to the display means 2 in accordance with the color data of the banknote stored in the memory 12, and the paper kind identification and control means. The notification signal is output from the 16 to the speaker drive circuit 34. At the same time, a drive stop signal is output from the winding type identification and control means 16 to the first motor drive circuit 38 and the second motor drive circuit 44. Subsequently, the display means 2 displays an error display for detecting two-species species detection or counterfeit bill detection. At the same time, a voltage is applied to the speaker 32 from the speaker driving circuit 34 to generate an alarm sound from the speaker 32.

At the same time, no voltage is applied from the first motor drive circuit 38 to the main motor 36 and no voltage is applied from the second motor drive circuit 44 to the transport motor 42. The counting operation stops because the bill is not moved.

The user then listens to the alarm sound generated from the speaker 32 and examines the bill by viewing the error indication displayed on the display means 2.

On the other hand, when the sheet type identification and control means 16 determines that the remaining banknote to be counted in the first banknote support 8 remains in the remaining banknote discrimination step S8 (in the case of YES), the fourth banknote discrimination step S12 Proceed to

In the fourth winding type discrimination step S12, the next bill in the loading position is pulled by mechanical means, not shown, connected to the main motor 36 so that the bill is moved to the color sensing and counting position in the housing 4. Move.

Next, in the paper sort comparison step S13, the color signal of the banknote is output from the color sensing means 14 to the paper sort identification and control means 16. Then, the paper type identification and control means 16 compares the color data corresponding to each paper type of the banknote stored in the memory 12 with the color sensing signal input from the color detecting means 14. Subsequently, the paper type identification and control means 16 determines whether the paper kind of the bill coincides with the reference paper type stored in the memory 12 in the reference paper type storage step S5. As a result of the discrimination, if it is determined that the paper currency of the paper money coincides with the reference paper money stored in the memory 12, the process proceeds to the count increasing step S6 (in the case of YES), and the count indicating the number of paper money is increased by one. .

When the sheet type identification and control means 16 determines that the sheet type of the paper money does not match the reference paper type stored in the memory 12 in the comparison of the paper type step S13 (in the case of NO), the standard paper type of the paper money Since it is a different kind of money, the process goes to step S14.

In the display of the two different paper / counterfeit bills and the stop counting step S14, a display signal is outputted from the paper kind identification and control means 16 to the display means 2 in accordance with the color data of the bill stored in the memory 12. A notification signal is output from the handpiece identification and control means 16 to the speaker driving circuit 34. At the same time, a drive stop signal is output from the winding type identification and control means 16 to the first motor drive circuit 38 and the second motor drive circuit 44.

Subsequently, the display means 2 displays an error display for detecting two-stage paper detection or counterfeit bill detection. The type of the error indication is, for example, "CF", "DD", "EH", "EC", "ED", "ASN", etc. The "CF" means that the bill is a fake bill. "DD" means that the banknote is a banknote of two different kinds of papers different from the standard winding type, and "EH" means a banknote of the half (Ha1f) side. "ED" means that the bills are stacked. In addition, said "ASN" means that banknotes are inclined and supplied.

At the same time, a voltage is applied to the speaker 32 from the speaker driving circuit 34 to generate an alarm sound from the speaker 32.

At the same time, no voltage is applied from the first motor drive circuit 38 to the main motor 36 and no voltage is applied from the second motor drive circuit 44 to the transport motor 42. The counting operation stops because the bill is not moved.

The user then listens to the alarm sound generated from the speaker 32 and examines the bill by viewing the error indication displayed on the display means 2.

According to the banknote counting apparatus and the control method according to the present invention as described above, there is a very excellent effect that can identify counterfeit banknotes and the like by detecting the color of the paper money by detecting the color of the paper.

In addition, when the banknotes of the different types of notes and the different types of notes are included in the bills of the reference kind, there is a very excellent effect that can accurately count the bills.
