The A / D converter 50 is composed of the image memory 51, the comparator 52, and the signal converter 53. The image memory 51 is a reference level of the left and right PDA sensors 40 and 41, that is, When the banknote does not pass through the PDA sensors 40 and 41, the initial output signal of the PDA sensors 40 and 41 that is output is imaged and stored.

The initial output signals of the PDA sensors 40 and 41 may form a certain level or may be distorted depending on the state of the photodiodes constituting the PDA sensors 40 and 41.

That is, it can be said that the reference level indicates the state of the PDA sensors 40 and 41 before counting the banknotes.

4 shows the capacitive sensing unit 10,

A sensing panel 1 through which the banknote passes;

A sensing surface 2 of copper plate material formed at a center portion of the sensing panel 1;

A sensing IC 3 for generating electrons and supplying them to the sensing surface, sensing a current change value in a circuit that is changed according to the capacitance value of a banknote passing through the sensing surface 2, and supplying the constant voltage IC 4 to the constant voltage IC 4; ;

A constant voltage IC 4 for supplying a current value sensed by the sense IC 3 to the amplification IC 5;

An amplifying IC 5 for amplifying the current supplied from the constant voltage IC 4 and supplying the amplified current to the output IC 6;

An output IC 6 for outputting the current value output from the amplification IC 5 as digital information or analog information; and as described, R1 to R9 are resistors, VR1 is a variable resistor, and D1 is a diode. C1 to C9 are capacitors.

The capacitive sensor configured as described above detects two kinds of windings and counterfeit by using different capacitance values of each paper currency.

That is, the bill has a total capacitance value which is the sum of the inherent capacitance value of the paper material and the capacitance value according to the magnetic or hologram included in the bill. Capacitive values are used to detect heterologous species and forgery.

When the circuit operates, the sensing IC 3 generates electrons to supply electrons to the sensing surface 2 of the sensing panel 1, and measures the current value in the circuit according to the supply of electrons.

If the banknote does not pass over the sensing surface 2, there is no electron lost, so the current value sensed by the sensing IC 3 is always constant.

However, when a banknote passes through the sensing surface 2, electrons donated to the sensing surface 2 are moved to the banknote by the intrinsic total capacitance value of the banknote, and the sensing IC (3) The current sensed at) changes and the sensing IC 3 detects the current change value and supplies it to the constant voltage IC 4.

The constant voltage IC 4 supplies the current change value supplied from the sensing IC 3 to the amplification IC 5, and the amplification IC 5 amplifies the input current change value by a predetermined level to output IC 6. The output IC 6 outputs an input current change value as digital information or analog information so that the central control unit 32 on the receiving side can determine whether the banknote is presently detected or counterfeit. .

For example, Lee's judgment detects 10000 won bills, and if 1,000 won bills pass through the sensing surface (2), the total capacitance values of 10000 won bills and 1000 won bills will be different from each other. Compared to when the 10000 won bill passes, a difference occurs in the current change value that is detected when the 1000 won bill passes.

In addition, since gastric obstruction has a lot of difference from magnetic component or metal component of pneumoconiosis, the current change value detected by the sensing IC 3 is different from that of the heterologous species. Will be done.

The color sensing unit 13 applied to the present invention is composed of two stages of blue sensor, one stage of red sensor, and one stage of green sensor, so as to have a total of four stages of detection, and the three primary color information detected by each sensor. It was possible to determine the color of each kind of bills.

Referring to the operation of the present invention configured as described above is as follows.

When the user puts a bundle of bills on the counter, the central control unit 32 moves the main motor 21 and the stacker motor 22 through the photocoupler 23 by the detection signal of the start input unit 24 that detects the bundle. By driving the bills to enter at a high speed, the counter sensing unit 14 counts the bills to enter and output, and the UV sensing unit 15 and the magnetic sensing unit 12 whether or not counterfeit bills entered The sensing information of the counter detector 14, the ultraviolet detector 15, and the magnetic detector 12 is detected and output to the A / D converter 17 through the analog switch 16 and then digitally detected. The signal is converted into a signal and input to the central controller 32.

In addition, the two-stage paper detector 11 configured by arranging a plurality of photo diodes accurately detects the size of bills to enter and outputs the detected information to the central controller 32 through the data bus 11a. The operation will be described in detail as follows.

When the power is supplied, the detection signals of the left and right PDA sensors 40 and 41 are supplied to the A / D converter 50 through the analog switches 42 and 43.

At this time, the image memory 41 stores the output signal, that is, the reference level (see (a) of FIG. 3), without the bill passing through the PDA sensors 40 and 41.

The reference level indicates a state in which the banknote does not pass through the PDA sensors 40 and 41, so that the output of the PDA sensors 40 and 41 in the current state (the light source is weakened due to defective photodiodes or foreign substances being caught). It is a reflection of the level form.

In this state, when the counting of the bills starts, the bills pass through the PDA sensors 40 and 41, whereby the output signals of the PDA sensors 40 and 41 are output as low as the part covered by the bills. It will be in a state as shown in FIG.

When the output signal as described above is input to the comparator 52, the comparator 52 compares the input signal with the reference level stored in the image memory 51, and the difference (T1) between the two signals. The size of the bill is calculated using the value and output to the signal converter 23.

That is, when the signal output from the PDA sensor 40, 41 at the time of bill counting is as shown in (b) of FIG. 3, the section T2 becomes the section not covered by the bill, and the section T1 becomes the section covered by the bill. The comparison unit 52 compares the output signal with the reference level and detects the portion T1 covered by the banknote as the difference value of the signals, and calculates the size of the banknote. The calculation result is the signal converter 53. The digital signal is outputted to the digital signal and then supplied to the controller 54.

The control unit 54 determines whether or not the banknote currently counted as the bank note information as the size information of the banknote, which is supplied from the A / D conversion unit 50, through the data bus 11a. 32).

In addition, when the paper money is fed, the capacitive sensing unit 10 detects the total capacitance value of the paper money passing through it, detects whether it is two or more kinds and counterfeit and outputs it to the central control unit 32, and the capacitive sensing unit 10 The detailed operation is omitted since it has been described in detail above.

On the other hand, the central control unit 32 sets the winding type of the banknote currently input as the size information of the banknote sensed by the two kinds of paper currency sensing unit 11 at the initial bill counting.

That is, when the size of the bill counted first is detected by the two-stage paper detector 11, the central control unit 32 is the size information of the paper money detected by the two-species paper detector 11 and each of the papers stored in itself Comparing the size is to automatically set the winding type of the banknote currently being put, this paper winding setting can be implemented by the user's key input unit 19 operation.

When the paper currency of the bill is set as described above, the central control unit 32 detects information (magnetic, ultraviolet, capacitance, size, color) and memory supplied from the sensors 10, 11, 12, 13, and 15, respectively. By comparing the reference information stored in (28) it is determined whether the current bill counts two different species and whether or not counterfeit.

As a result of the determination, if a heterologous species or counterfeit is found, a control signal for displaying that the heterotrophic species and a counterfeit has been found through the data bus 20 is displayed to indicate that the heterogeneous species have been found through the display unit 18. At the same time, the motor to stop the movement of bills to stop, and output a predetermined buzzer to inform the worker that the two-note paper bills were found.

In addition, if the result of the determination does not find a different kind or counterfeit, the number of bills to be fed is continuously counted and the number of bills to be input is displayed to the worker.

As described above, the determination of the different kind and counterfeiting of the banknote is detected by the ultraviolet sensing unit 15, the two different species sensing unit 11, the magnetic sensing unit 12, the color sensing unit 13, and the capacitance sensing unit 10, and the like. By using a combination of various information, the reliability of heterologous species and gastric pulmonary detection can be further improved.

In addition, the determination of whether the right or wrong papers of the central control unit 32 may be transmitted and stored to the PC 30 through the serial communication unit RS-232c, and the alarm display may be displayed through the auxiliary display unit 31.

Such two kinds of paper and whether the counterfeit determination is performed until the detection signal of the end input unit 25 for detecting the last part of the bill is input, each component is operated by the driving power provided from the power supply unit 27. .

Unexplained reference numeral 26 is an encoder input unit.

On the other hand, in the present invention, it is possible to implement the function of counting bills of two different kinds of paper, and summing the face value of the two different kinds of paper.

That is, when the user operates the key input unit 19 to select the two-segment sum function, the central control unit 32 detects the two kinds of bills as information detected from the respective sensors 10, 11, 12, 13, and 15. While determining whether or not, by using the size information detected from the two kinds of paper detector 11 and the color information detected by the color sensor 13 to determine the winding type of the bill currently detected, and separating all the two different paper bills determined The count is stored in the summing processing unit 33.

For example, if the user inputs 10 sheets of 1000 won, 5000 won, and 10,000 won bills, the central control unit 32 is the sensing information detected by the two-stage paper detecting unit 11 and the color detecting unit 13, respectively. While judging the number of papers, it is separated and counted and stored in the summing processing unit 33. After all the bills have been counted, the summing processing unit 33 sums the total amount of the face value and the count value of the papers stored in the central control unit. It outputs to the display part 18 via the 32.

As described above, the function of summing the amounts of heterogeneous species may be implemented. The heterogeneous species detecting unit 11, the color detecting unit 13, and the capacitance detecting unit 10 and the like have significantly improved functions compared to the prior art. In addition, by analyzing the information sensed by each of the detection unit (11, 13, 10) can be possible by accurately determining whether the two-note species of the bill.

As described above, the present invention is a banknote that is counted by combining the detection result of the magnetic sensing unit, the ultraviolet sensing unit, and the like, the size information of the banknote detected by the size sensor, and the counterfeit information detected by the capacitance sensing unit. Banknotes that have the ability to discriminate between two different types and counterfeits, and to combine the face value of the different types of notes when adding multiple notes The effect of providing a counter can be expected.
