The central control unit 20 is set to determine the bill type of the bill as the size of the bill sensed by the left and right light receiving units 22a and 22b, and also to determine the counterfeit if the ultraviolet ray level penetrating the bill is below the reference value.

Reference numeral 8 denotes an encoder input unit, reference numeral 9 denotes an end input unit, reference numeral 24 denotes a serial communication unit which allows the central control unit 20 and an external device PC 25 to communicate with each other. 26 denotes an auxiliary display unit for displaying whether or not counterfeiting and dual winding according to the control of the central control unit 20.

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 detection signal of the start input unit 7 that senses the bundle is supplied to the central control unit 20, and the central control unit 20 supplies the main motor 4 and the stacker motor 5. The main motor 4 and the stacker motor 5 are driven by the control signal output through the photocoupler 6 to supply a control signal for driving the photocoupler 6 to the photocoupler 6. The rollers are driven, whereby the bills loaded on the counter are fed at a high speed.

At this time, the counter detection unit 14 counts and enters the bill entered, and the infrared detector 12 detects the counterfeit of the entered bill and outputs it, and the color detector 13 detects the color of the bill. Output

The signals sensed and output by the detectors 12 to 14 are input to the A / D converter 16 through the analog switch 15, and then converted into digital signals and input to the central controller 20.

In addition, the ultraviolet sensor 17 applied to the present invention detects the size of the bill and the amount of UV transmission and supplies it to the central control unit 20.

The LEDs 23 of the left and right light emitting parts 21a and 21b constituting the ultraviolet sensor 17 emit light of the ultraviolet range to the light receiving parts 22a and 22b, and the light emitting parts 21a and 21b and the light receiving part 22a. When the banknote passes through the banknotes 22b, the light supplied to the light receiving units 22a and 22b is reduced by the size of the banknotes, and the light receiving units 22a and 22b sense the size of the light detected in response to the banknotes and amplify the banknotes. Supply to the central control unit 32 through (18).

Therefore, the central control unit 20 distinguishes the types of bills counted by the bill size patterns T1, T2 and T3 provided from the light receiving units 22a and 22b.
