Abstract
The utility model relates to the bill/cash detection field, particularly relates to an optically variable ink detection device of banknotes, and solves the problems that authenticity of banknotes is difficult to detect through ink optically variable characteristics and the like in the prior art. The device comprises a RGB light source and a photoelectric sensor, wherein the RGB light source is disposed corresponding to an ink area of a banknote, and the photoelectric sensor is disposed in the reflection or transmission direction of the RGB light source. The RGB light source and the photoelectric sensor are respectively disposed at two sides of a vertical plane of a banknote, and the photoelectric sensor is disposed symmetrically to the RGB light source in a direction where light is reflected from the ink area of the banknote. Or the center line of the RGB light source is perpendicular to the ink area of the banknote, the RGB light source is located at one side of the ink area of the banknote, the photoelectric sensor is disposed in a direction where light is reflected from the ink area of the banknote, and the photoelectric sensor is located at the other side of the ink area of the banknote. The optically variable ink detection device is capable of accurately detecting optically variable figure characteristics of the ink area, and detecting the authenticity of the banknotes by ink aberration through ink optically variable aberration transformation.
Description
Technical field
The utility model relates to the ticket money detection range, is specially a kind of banknote photochromatic printing ink pick-up unit.
Background technology
At present, the counterfeit money manufacturing technology of mixing the spurious with the genuine makes people hard to guard against.The method that bank note detects is a lot, and the staff finds that the difference of the light of printing ink change feature is bigger on genuine notes and the counterfeit money.So, how further to distinguish between truth and false by the light change feature of printing ink, be problem anxious to be solved at present.
The utility model content
The purpose of this utility model is to provide a kind of banknote photochromatic printing ink pick-up unit, solves the light that is difficult in the prior art by printing ink and becomes problems such as feature detection authenticity of banknotes.
The technical solution of the utility model is:
A kind of banknote photochromatic printing ink pick-up unit, this device is provided with rgb light source, photoelectric sensor, and the rgb light source is corresponding with the inked areas of banknote, in the direction of rgb light source reflection or transmission photoelectric sensor is set.
Described banknote photochromatic printing ink pick-up unit, rgb light source and photoelectric sensor are arranged at the vertical plane both sides of banknote respectively, and the rgb light source is symmetrical arranged photoelectric sensor along the direction of the inked areas reflection of banknote.
Described banknote photochromatic printing ink pick-up unit, the angle between rgb light source center line and the photoelectric sensor center line is 70-110 °.
So banknote photochromatic printing ink pick-up unit, rgb light source center line is perpendicular to the inked areas of banknote, the rgb light source is positioned at inked areas one side of banknote, and the direction in the rgb light source along the inked areas transmission of banknote arranges photoelectric sensor, and photoelectric sensor is positioned at the inked areas opposite side of banknote.
Described banknote photochromatic printing ink pick-up unit, an end corresponding with banknote at photoelectric sensor arranges optical filter.
Described banknote photochromatic printing ink pick-up unit, the rgb light source is array light source.
The beneficial effects of the utility model are:
The light that the utility model can accurately detect inked areas becomes graphic feature, by the conversion of printing ink phototropic difference, detects authenticity of banknotes by the printing ink aberration, and it is obvious that it detects effect, and cost is lower.
