Abstract
The utility model relates to a light-filtering truth-false paper money identifying device used for identifying the truth-false paper money, which is composed of an optical filter, a shading gear, and an observation opening. The natural light and the light approaching to the daylight color obtain the ultraviolet light without containing visible light (or only containing partial visible color light) through the optical filter. Then, the obtained ultraviolet light can be used for observing fluorescent anti-counterfeiting marks on the true paper money. The truth-false paper money identifying device which is made by using the method has the advantages of simple principle and structure, no need of a power supply, convenient operation, and portability. The utility model can be suitable for being used by various collection persons.
Description
A kind of true and false paper currency discriminator of optical filtering formula that is used to discern true and false bank note.
Present true and false paper currency discriminator is ultraviolet light irradiation 50 circles (or the 100 circles) Renminbi that utilizes UV-lamp to send, and then the fluorescent anti-fake mark on the genuine note coin face will display.Though utilize this Discr. to differentiate that true and false bank note is reliable, it must could use by power supply.Be difficult for carrying, often personnel's use of change of place is not suitable for collecting money.
The purpose of the true and false paper currency discriminator of the utility model optical filtering formula is: from natural light with near the ultraviolet that is not contained visible light the visible light of color of sunshine, with solving above-mentioned contradiction.
Below in conjunction with accompanying drawing the utility model is described further:
Figure is a synoptic diagram of the present utility model.
The utility model light-filtering truth-false banknote identifier, by optical filter 1, shading gear 3, observation panel 2 forms.
All contain ultraviolet in natural daylight (referring to direct sunlight, scattering daylight, diffuse reflection daylight) and the light (referring to fluorescent lamp light, the incandescent lamp light that colour temperature is higher) near color of sunshine. Utilize a slice can see through ultraviolet, and the blue cobalt glass sheet of the optical filter 1(that block visible light sees through), the visible light ultraviolet of (or only containing the visible coloured light of part) just can not contained. With the ultraviolet light irradiation bank note that this way obtains, can see the fluorescent anti-fake mark on the true bank note.
In actual use, this optical filter 1 parallel button is placed on apart from the anti-counterfeiting label place of two to five centimetres of bank note; Between optical filter 1 and the coin face gap around, surround with shading retaining 3.In mouth, watch the coin face from observation panel 2, just can see the fluorescent anti-fake mark on the genuine note coin face.
This Discr. principle and simple in structure does not need distribution source again, and is easy to use, can carry, and is fit to all kinds of cashiers and uses.
