5 is a flowchart illustrating a counterfeit bill discrimination process according to an embodiment of the present invention.

In step 100, the switch on the counterfeit money discrimination apparatus according to the present invention is turned on and initialized, and in step 102, a dollar for determining whether the counterfeit is counterfeit is set. In step 104, after confirming that the dollar set by the paper feed sensor is detected, if the dollar is detected, the sensing signal is applied to the central processing unit. Subsequently, in steps 106 and 108, the stepping motor is driven by forward rotation to move the dollar to the discriminating unit of the counterfeit bill discrimination apparatus through the first feed roller.

In operation 110, first, the pattern data about the transmitted infrared ray transmission amount of the dollar input through the infrared sensor is read up to the 400th in the length direction of the bank note to detect the thickness and length of the dollar. Subsequently, in step 112, red / green (R / G) and blue / green (B / G) color-printed on the dollar passing through the infrared sensor through the color sensor is detected. In this case, the color sensor uses a white LED as a light emitting unit, and by using a color sensor as a light receiving element, sends color data of two types (R / G, B / G) of visible light transmitted to the central processing unit to the central processing unit. Compared with color data such as copying counterfeit, cotton, and non-fluorescent paper, it detects whether the dollar is counterfeit.

Subsequently, in step 114, the serial number of the dollar passing through the color sensor is sensed through the contact image sensor which is a feature of the counterfeit bill discrimination apparatus according to the present invention. The dollar serial number detected by the contact image sensor is automatically output through the printer later. In step 116, the magnetic line formed in the longitudinal direction of the dollar is detected through the magnetic sensor. The magnetic sensor digitally pulses an analog signal for a magnetic pattern of dollars, reads the number of pulses, and sends the data to the central processing unit. Subsequently, in step 118, the lipid of the dollar passing through the magnetic sensor is detected by the ultraviolet sensor. The ultraviolet sensor irradiates the dollars injected with the ultraviolet lamp and the ultraviolet filter as the light emitting unit, and compares the magnitude of the visible light transmitted according to the amount of ultraviolet light in the dollars using the photodiode as the light receiving element to determine whether the dollars are counterfeit. .

As described above, the signals detected by the infrared sensor, the color sensor, the magnetic sensor, and the ultraviolet sensor are sequentially input to the central processing unit. In step 120 and 122, the central processing unit outputs data input from the infrared sensor. Distinguish the paper species of the bill by reading it. In operation 124, the CPU reads output data inputted from the color sensor, the magnetic sensor, and the ultraviolet sensor. In operation 126, the CPU determines whether the inputted dollar is spent based on the read data. As a result of the determination, if it is determined that the cigarette is occupied in step 128, the paper types of the bills are classified and displayed on the LCD, and in step 130, the amount for each paper type is calculated. In step 132, data about the serial number of the dollar and the dollar amount detected by the contact image sensor are transmitted to a print device connected through a printer port to print the serial number and amount of the dollar. Then, in step 134, the dollar for which the counterfeit determination is completed is discharged to the outside.

On the other hand, if it is determined that the counterfeit is detected in step 126, the flow proceeds to step 136 and an error content is displayed on the LCD together with a buzzer sound. The error is caused by a magnetic error (EM), a UV light, or a geological error of the dollar, indicating that the magnetic component of the magnetic pattern formed on the injected dollar is weak or incorrectly patterned, or there is no magnetic pattern at all. EU (UV error) to indicate an error, EI (IR error) to indicate an error due to a pattern error printed on the dollar, ET (Thickness error) to indicate that the thickness of the lipid is thicker or thinner than the reference, and the dollar length Length error (EL) to indicate an error due to longer or shorter than the standard, input error (ED) to indicate an error when another dollar is input before the previous dollar is fully discharged, and EJ to indicate an error due to dollar damage. Paper Jam error), an EP (Photograph) that indicates an error due to a contrast error of color patterns printed on dollars. error).

Subsequently, in steps 138 and 140, when the inputted dollar is determined to be counterfeit due to the above various causes of error, the stepped motor is driven in reverse rotation to discharge the determined counterfeit dollar.

On the other hand, although not shown in the drawings, when a large amount of bills to be discriminated, it may be provided with a separator that can separate the dollar determined as pneumatic and the dollar determined as counterfeit, respectively, by volume.

As described above, the present invention has been described in accordance with the drawings and limited by way of example, but various changes and modifications are possible to those skilled in the art without departing from the technical spirit of the present invention according to the matter. Of course.

According to the present invention described above it can be obtained the following effects.
