Abstract
The utility model relates to a contact-type image sensor, which belongs to the technical field of the image read-out device, and is characterized in that a framework on which a light source is opposite to a lens is provided with a transmission groove, a transmission light source is arranged inside the transmission groove, and the contact-type image sensor can be used for identifying the anti-fake label inside a paper currency so as to judge the authenticity of the paper currency. When in use, two contact-type image sensors providing the transmission light source and reading the transmission light are respectively arranged at two sides of the paper currency, wherein the transmission light which is transmitted by the contact-type image sensor providing the transmission light source can pass through the paper currency to be received by the contact-type image sensor for reading the transmission light. The anti-fake label inside a true paper currency has unique characteristic rule, so when the transmission light is used for radiating the true paper currency and the counterfeit paper currency, the transmission light which passes through the true and the counterfeit paper currencies and is received by the contact-type image sensor is different. By analyzing and processing the transmission light which passes through the paper currency and is received by the contact-type image sensor for reading the transmission light, the obtained information is compared with relevant information of the true paper currency so as to effectively identify the authenticity of the paper currency.
Description
Technical field:
The present invention relates to a kind of image read-out, particularly a kind of contact-type image sensor that on the basis of traditional contact-type image sensor, has increased transmitted light source.The utility model contact-type image sensor can be used to discern the inner anti-false sign of bank note, reaches the purpose of effective identification note true and false with this.
Background technology:
We know, existing all-in-one multifunctional machine, dedicated scan instrument, facsimile recorder, the employed contact-type image sensor of pattern recognition devices such as cash inspecting machine, as shown in Figure 1, be 1 time wiring board 6 to be arranged at framework, opto-electronic conversion chip 5 is arranged on the wiring board, opto-electronic conversion chip top is provided with lens 2, lens one side is provided with light source 4, and the framework top is provided with the light-passing board 3 that carries original copy.During work, the light transmission light-passing board that light source sends shines on the scanned object, a part of reflected light on the scanned object sees through light-passing board and enters optical lens, the reflected light that comes out from the other end of optical lens shines on the opto-electronic conversion chip 5, opto-electronic conversion chip 5 be by many photosensitive areas and can will shine the light of each photosensitive area carry out opto-electronic conversion, and the driving circuit of signal output formed, the light that receives converts electric signal to after overdrive circuit output, outwards export as image (literal) information, original copy constantly moves, and the image of being put down in writing on it (literal) information will be read continuously.When the light that has only light source to send ran into reverberation, the opto-electronic conversion chip could be worked after receiving the light that reflects, and according to the principle of work of traditional contact-type image sensor, we are defined as reflection source with its light source.In order to make bank note have certain anti-counterfeit capability, usually bank note is done some false proof processing, for example can increase some and have the anti-false sign of specific rule in the surperficial or inside of bank note.When the anti-false sign of note surface makes by specific rayed genuine notes and counterfeit money, the light difference that reflects, traditional contact image sensor utilizes these characteristics just, discern the anti-false sign of note surface by reading reflected light that bank note reflects, reach the purpose of the identification note true and false.For the anti-false sign of bank note inside, only can't discern, also the true and false of identification note effectively just by reading catoptrical method.
Summary of the invention:
Technical problem to be solved in the utility model is: traditional only can read catoptrical contact-type image sensor, can't discern the anti-false sign of bank note inside, also the true and false of identification note effectively just.Proposing has a kind ofly increased transmitted light source on the basis of traditional contact-type image sensor, can be used to discern the contact-type image sensor of the inner anti-false sign of bank note.
The technical scheme that its technical matters that solves the utility model adopts is:
A kind of contact-type image sensor, comprise wiring board, carry the opto-electronic conversion chip that is arranged in a straight line on the wiring board, opto-electronic conversion chip top is equipped with lens, one side of lens is provided with light source, and the framework that can hold above-mentioned wiring board, lens, light source, and the top of framework is provided with the light-passing board that carries original copy, it is characterized in that light source is provided with the printing opacity groove back to the framework of lens one side, is provided with transmitted light source in the printing opacity groove.
The utility model contact-type image sensor can be used to discern the anti-false sign of bank note inside, comes the true and false of identification note with this.Provide transmitted light source and two contact-type image sensors that read transmitted light to be put in the two sides of bank note respectively during use, wherein provide the transmitted light of the contact-type image sensor emission of transmitted light source can penetrate bank note, the contact-type image sensor that is read transmitted light receives.The anti-false sign of genuine notes inside must have its exclusive characteristic rule, so when using transmitted light irradiation genuine notes and counterfeit money, transmiting genuine notes, to be touched the received transmitted light of formula imageing sensor with counterfeit money be different.By carrying out analyzing and processing to penetrating the received transmitted light of contact-type image sensor that bank note is read transmitted light, the information that obtains and the relevant information of genuine notes compare, thereby reach the purpose of effective identification note true and false.
The utility model contact-type image sensor reasonable in design, transmitted light source and the traditional contact-type image sensor that only has reflection source are integrated in one, this just makes that the utility model contact-type image sensor volume is little, easy to use flexible, this design is for realizing that the whole set equipment miniaturization is significant.During the work of the utility model contact-type image sensor, transmitted light source control is easy, does not need the parts of extra control transmitted light source, has also reduced the trouble in manufacturing simultaneously, has reduced cost greatly, is suitable for producing in enormous quantities.
The transmitted light source of the utility model contact-type image sensor and opto-electronic conversion chip can be on same wiring boards, also can be on different wiring boards.Because the kind of the bank note that need differentiate is a lot, the anti-false sign of bank note inside also can be diversified, according to actual conditions, need to adopt the light of multiple different colours to come it is discerned, so the utility model contact-type image sensor can adopt ruddiness, green glow, blue light, white light, infrared light, the multiple light sources of different colors of ultraviolet light or the like is as transmitted light source.
