The upper CIS sensor 641 and the lower CIS sensor 642 are respectively installed on the upper bill guide frame 180 and the lower bill guide frame 190, the lower bill guide frame 190 is installed on the bottom plate, and the bill discharging plate is installed on the upper bill guide frame 180.
The magnetic reader 650 is used for reading magnetic marks (magnetic ink) on the banknote, thereby further judging the authenticity of the banknote.
When the paper money detection device is used, paper money enters the paper money channel 101 from one end of the paper money channel, which is close to the second paper money inlet plate 170, then the paper money is identified after the paper money image is acquired through the CIS sensor, then the paper money is input into the detection module to judge the thickness of the paper money or judge whether the paper money is clamped at the position, then the magnetic mark of the paper money is input into the magnetic reader 650 to read the magnetic mark of the paper money for further verification, the general magnetic mark is a paper money code, the paper money code is compared with a paper money code library of a bank, if yes, the paper money is judged to be true paper money, otherwise, the paper money is false paper money, and finally the paper money detection device is output. The method is in a pipelining mode, has high efficiency and high identification accuracy, and can meet the current requirements.
The present invention is not described in detail in the present application, and is well known to those skilled in the art.
The foregoing describes in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be made in accordance with the concepts of the invention by one of ordinary skill in the art without undue burden. Therefore, all technical solutions which can be obtained by logic analysis, reasoning or limited experiments based on the prior art by the person skilled in the art according to the inventive concept shall be within the scope of protection defined by the claims.
