2. Description of the Related Art A bill has a complicated pattern or watermark formed on its surface so that the counterfeit bill cannot be easily made by color copying or simple printing. 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 is more difficult to identify counterfeit bills in used bills and in places where the lighting is dark.

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, the ultraviolet light emission pattern printed on the surface of the bill by the ultraviolet reactive ink is embossed. For printed banknotes containing such an ultraviolet light emission pattern, an ultraviolet irradiation lamp is installed inside a counterfeit note detection device such as a tabletop type, and ultraviolet rays are irradiated to the banknote sent from the banknote insertion slot, and this pattern is displayed. It was read and the true bill and the false bill were identified based on the read result.
