Embodiment Construction

[0028] Preferred implementation forms are described below with reference to the accompanying drawings.

[0029] In these drawings, reference numeral 1 denotes a light-emitting element of ultraviolet rays, particularly, a light-emitting element having ultraviolet rays having a wavelength of 370 nm. The UV light-emitting element 1 like Figure 4~7 As shown, together with an infrared light emitting element 3 having near-infrared rays and a pair of light emitting elements 2 and 2 having red light and visible light rays, they are mounted on a machine that moves banknotes B under the action of conveying components such as rollers or belts. on the bottom guide or the top guide.

[0030] Here, the ultraviolet light-emitting element 1 can also be arranged on the straight line of the middle line along the walking direction of the near-infrared infrared light-emitting element 3 and the banknote B, for example, forming Figure 6 settings shown. The infrared light-emitting element 3 wit...

Abstract

PURPOSE: A method for identifying the counterfeit of money is provided to discriminate the counterfeit in a naked eye by the change of the color and the clear difference of the waveform and wavelength between the original data and the data obtained from the counterfeit. CONSTITUTION: A method for identifying the counterfeit of money includes the steps of: irradiating the light from the light emitting device for the traveling money and discriminating the counterfeit of the corresponding money by comparing the data of the previously prepared original money with the data carried on the light after the irradiation, wherein the light emitting device includes at least one ultraviolet rays of light emitting device and the original data is compared with the data obtained from the transmitted or the reflected ultraviolet rays by reflecting the ultraviolet rays on the corresponding money.

Description

technical field [0001] The present invention relates to a method and device for authenticating banknotes. In particular, the present invention relates to banknotes that are effective in checking counterfeit banknotes formed by sophisticated color copiers, color scanners connected to personal computers, printers, etc. that have become popular in recent years. The true and false identification method and device thereof. Background technique [0002] In the past, authenticity identification of banknotes has been realized by checking the magnetic field distributed on the banknotes, checking watermarks, embossing, or image recognition and many other objects. However, in the past methods, in many cases, the inspection function can be passed only through simple processing, especially the counterfeit banknotes formed by the image processing of color copiers and color scanners developed by high technology in recent years. Said to be close to the real banknotes, it is difficult to co...
