Abstract
The utility model relates to a transmitted reflected spectrum counterfeit checker which is provided with a bracket provided with two through holes: one through hole is provided with an ultraviolet source and ultraviolet light transmission glass, and the other through hole inside is provided with a photoelectric sensor; a position above the bracket corresponding to the ultraviolet source is provided with a photoelectric sensor. The utility model has the advantages of simple structure, easy fabrication and convenient operation, can effectively raise the reliability of ultraviolet light counterfeit check, can be matched with financial machines and tools, such as various types of currency count machines, counting machines, etc., and can be used as a replacing product for the existing ultraviolet light counterfeit checker.
Description
The utility model is a kind of Transflective spectrum antiforge detecting device.
The glimmering optical antiforge detecting of traditional Renminbi generally is that ultraviolet ray is shone on the Renminbi, gets its reflectance spectrum, compares with standard ultraviolet light reflectance spectrum after machine is handled as calculated, and reaches the purpose of discerning authenticity of banknotes; Along with improving constantly of pseudo-technology for making, counterfeit money ultraviolet reflection spectrum and genuine notes ultraviolet reflection spectrum are more or less the same, and cause the pseudo-reliability of machine inspection not high, with opportunity, have a strong impact on national financial order to the counterfeit money circulation.
The purpose of this utility model be to overcome the deficiency of prior art and provide a kind of simple in structure, processing and manufacturing easily, the pseudo-effective Transflective spectrum antiforge detecting device of inspection.
The utility model is to adopt following proposal to realize: it has a support, support is provided with two through hole, a through hole is provided with a ultraviolet source and a ultraviolet light transmissive glass, be provided with a photoelectric sensor in another through hole, the position corresponding with ultraviolet source is provided with a photoelectric sensor above support.
Concrete structure of the present utility model describes in detail below in conjunction with accompanying drawing.
Accompanying drawing is the utility model structural representation.
See accompanying drawing, the utility model is made up of support 1, ultraviolet source 2, ultraviolet light transmissive glass 3, photoelectric sensor 4, photoelectric sensor 5, described support 1 is provided with two through hole 6,7, ultraviolet source 2, ultraviolet light transmissive glass 3 are installed in the through hole 6, photoelectric sensor 4 is installed in the through hole 7, and position corresponding with through hole 6 above support 1 is provided with a photoelectric sensor 5.
Principle of work of the present utility model is summarized as follows: when banknote to be measured or securities pass through support 1 top, the ultraviolet light that ultraviolet source sends is transmitted through the last branch of banknote or securities through ultraviolet light transmissive glass 3 and forms reflected light and received by photoelectric sensor 4, another part sees through measured object and forms transmitted light by photoelectric sensor 5 receptions, and produce a reflectance spectrum and transmitted spectrum respectively, these two kinds of spectrum compare with the standard reflection spectrum, the transmitted spectrum that are stored in the computing machine after external Computer Processing, can judge the true and false of measured object immediately; And when the wavelength regulation of ultraviolet source during to certain limit, qualitative leap will take place in the pseudo-reliability of its inspection.The utility model can effectively improve the reliability of ultraviolet optical antiforge detecting owing to adopt said structure, improves the false proof means in financial field, effectively reduces the approach of counterfeit money circulation.
In sum, the utility model is simple in structure, processing and manufacturing is easy, easy to use, the reliability that can effectively improve the ultraviolet optical antiforge detecting, be suitable for and the supporting uses of financial machine and tool such as various model paper money counters, cleaning-sorting machine, can be used as the renewal product of existing ultraviolet light antiforge detecting device.
