Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for discriminating between genuine bills and counterfeit bills among a large number of bills based on an ultraviolet light emission pattern or a magnetic pattern printed on the bills, and particularly to various bills in many countries. The present invention relates to a bill validator capable of dealing with.

[0002]

2. Description of the Related Art A bill has a complicated pattern or watermark formed on its surface so that a counterfeit bill cannot be easily produced by a color copying machine or a printing device. However, due to the recent improvements in the performance of color copiers and printing devices of personal computers, sophisticated counterfeit bills have been created. Therefore, it becomes difficult for the storefront to instantly discriminate the genuine bill and the counterfeit bill based on the complicated pattern and watermark. In particular, it has been more difficult to accurately identify counterfeit bills in used bills and dark places.

Therefore, conventionally, a pattern that is exposed by ultraviolet irradiation is printed on the surface of a bill, or such paper is used,
A method has been proposed for easily finding counterfeit bills. In this pattern, for example, an ultraviolet light emitting pattern printed on the surface of the bill by the ultraviolet reactive ink is embossed. For banknotes printed with such an ultraviolet light emission pattern, an ultraviolet irradiation lamp is installed inside a counterfeit note finding device such as a tabletop type, and the banknotes sent from the banknote insertion slot are irradiated with ultraviolet rays, and this pattern is read, Based on the reading result, the true bill and the false bill were identified.

[0004]

However, with the above-mentioned conventional counterfeit note finding device, although a banknote having a predetermined ultraviolet light emission pattern can be identified, in view of the current situation where many kinds of banknotes in various countries are in circulation. In general retail stores, it is difficult to easily find counterfeit bills from a large number of bills. Further, there is a problem that long-term observation of the ultraviolet light emitted from the ultraviolet irradiation lamp of such a counterfeit note finding device adversely affects the body.

On the other hand, there are some foreign bills that discriminate between genuine bills and counterfeit bills based on the magnetic pattern printed on the bills instead of the ultraviolet emission pattern. Therefore, the conventional counterfeit note finding device has a problem that a counterfeit note cannot be found for a bill printed with only such a magnetic pattern.

The present invention was created to solve the above problems. That is, an object of the present invention is to provide a counterfeit bill identifying apparatus which can reliably discriminate counterfeit bills from among many kinds of bills and can handle a large number of bills for a long time without adversely affecting the body.

FIG. 6 is a perspective view showing a genuine Taiwan Yuan banknote to which ultraviolet light is applied. In the counterfeit bill identifying device 1, when the bill B is spread on the inspection table portion 3 and the switch 7 is turned on, the ultraviolet irradiation light emitted from the ultraviolet irradiation light source 4 strikes the surface of the bill B. Whether the bill is a fake bill or a true bill is discriminated by the presence or absence of a pattern appearing on the bill B due to the irradiation of ultraviolet rays. When the bill is a true bill, the “mark” appears in Japanese bills and the letters “Bank of Japan” appear (see FIG. 4). However, when this bill is a counterfeit bill, such an ultraviolet light emission pattern does not appear, and therefore it can be determined as a counterfeit bill.

Further, the ultraviolet light emission pattern printed on the bills differs from country to country. For example, American dollar bills
The ultraviolet light emission pattern stands out like a band (see FIG. 5). In addition, the Taiwanese original banknote has multiple fluffs (see Fig. 6). As described above, since the type of the ultraviolet light-reactive ink of the ultraviolet light emission pattern printed on the banknote is different for each country, the wavelength of the ultraviolet light of the ultraviolet light irradiation light source 4 is adjusted accordingly.
