Central Laboratories of the Ministry of Economic Affairs and Consumer Cooperatives, India 4 2 5 ί.) 3 1 Α7 * Β7 V. Description of the invention () Judging the falsity of the printed paper 16. The identification signal is usually generated by using a piece of printed paper. After placing the fake printed paper in the printed paper identification system 10, the sensing signal generated by the light sensor 1 4 can be stored in the memory of the controller 5 as the identification signal. Because the types of light source 12 and light sensor 14, the paper quality of printed paper 16, the printed image, the color of ink, and the material will all affect the generation of sensing signal 24, so 10 sensing signals 2 4 can It is regarded as the characteristic curve of the printed paper sheet 16. By comparing this characteristic curve with the counterfeit characteristic curve, it is possible to quickly detect the falsification of the printed paper 16. However, because the printed paper 16 is like a banknote, it is easily subject to abrasion and decoloration after repeated use. This decolorization 15 phenomenon will affect the sensing signal 2 4 generated by the printed paper 16 and make its waveform amplitude. There are great changes, which make the identification of the old printed paper 16 very difficult. In general, the printing paper identification system 10 will allow some signal errors to allow the fakes of the printing paper to pass the test. The smaller the margin of error, the better the straight and complete printed paper will pass the test. In contrast, the smaller the error range, the easier it is to reject old printing paper counterfeits. However, relaxing the margin of error makes it easy for fakes to pass the test. This situation makes the printing paper identification system 1 0 effective -------------------- order- ^ (please read the precautions on the back before filling this page) 425531 A7 B7 Yin Fan, Consumer Work Cooperative of Zhongli Standards Bureau, Ministry of Economic Affairs. Therefore, the main object of the present invention is to provide a new printing paper identification system to solve the above problems. 5 Brief description of drawings Figure 1 is a schematic diagram of the structure of a conventional printing paper identification system.

Figure 6 is the sensing signals 6 2 and 6 4 generated by the sensors 4 0 a and 40 3d in Figure 4bis. The system 30 includes a paper feeding mechanism 46 for driving the printing paper sheet 36, a sensing mechanism 44 for sensing the printing paper sheet 36, and a controller 42.

Order 4 4 This paper wave size is applicable to Chinese national standards (CNS > A4 specifications (210X297 mm) 4 2 5 5 3 1 a? B7 V. Description of the invention () The paper feeding mechanism 4 6 includes a paper feeding slot 32 and a pusher 34 for carrying the printing paper sheet 36 through the paper feeding slot 32. The printing paper sheet 36 is approximately rectangular, such as a banknote, for example. 5 The position of the long strip-shaped area is the same as the long strip-shaped area 2 2 on the printed paper sheet 16 shown in FIG. 2. The sensing mechanism 4 4 is provided on the two sides of the paper feed slot 3 2 and includes There are two light sources 3 8 a and 3 8 b arranged horizontally and having different wavelengths provided on one side of the paper feed slot 32 and a sensing device 48 is provided on the other 10 side of the paper feed slot 32. The sensing device 4 8 includes two sensors 40a and 40t corresponding to the light sources 38a and 38b, which are arranged horizontally and are used to sense the light from the light sources 3 8 a and 3 8 b respectively to generate two corresponding sensations. Measurement signal. When the printed paper sheet 36 is horizontally passed through the paper feed slot 32, its long strip-shaped area will pass 15 horizontally through the light sources 3 8 a and 3 8 b to make the sensing device 4 8 It is able to generate the sensing signals. 6 2 and 6 4. The seal of the Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs (please read the precautions on the back before filling out this page). The light sources 38a and 38b are two light sources that emit light of a specific wavelength. Diodes (LED >). Sensors 40 a and 20 4 0 b are full-band (A 1 1-B and) sensors used to sense light sources 3 8 a or 3 8 b. Light. Light source 38, corresponding sensor 40a, and another set of light sources 3 8b, and sensor 4 ◦ b is separately arranged on the paper feed slot 32 so that each sensor can only sense To the light source corresponding to it. As the light source 3 8 a, this paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm) B7 B7 Printed by the Male Workers Consumer Cooperatives of the Central Procurement Bureau of the Ministry of Economic Affairs ) And 3 8 b have different wavelengths, so sensors 40 a and 4 ◦ b can also be replaced by sensors that can only sense a specific wavelength, so that each sensor can only sense its corresponding Light of a specific wavelength emitted by the light source, and will not be interfered by 5 of other light sources. Controller 4 2 is electrically connected The paper feeding mechanism 46 and the sensing mechanism 44 are used to control the paper feeding mechanism 46 to pass the long strip-shaped area on the printed paper sheet 36 through the light sources 38a and 38b so that the 10 sensing device 4 4 can sense The light transmitted to the light sources 3 8 a and 3 8 b through the strip-shaped area on the printing paper sheet 3 6 and the corresponding sensing signals 6 2 and 6 4 are generated, and the sensing signal 6 is used. The difference between 2 and 6 constitutes a characteristic signal 66, and compares the characteristic signal 66 with a plurality of pre-stored 15 identification signals 5 6 to determine the forgery of the printed paper 36. The controller 42 includes a memory 52 for storing an identification program 5 4, sensing signals 62 and 64 and a plurality of identification signals 5 6, and a processor 50 for executing the identification program 5 4 020 identification program 5 4 is used to compare the difference between the sensing signals 6 2 and 6 4 to form a characteristic signal 6 6, and then compare the characteristic signal 6 6 with a plurality of identification signals 5 6 to determine the forgery of the printed paper 3 6. . As the printed paper 3 6 can be applied to different paper sizes, it is applicable to the Chinese National Standard (CNS) A4 (210 X 297 mm)-:-„----- Ί .., installed ---- --Order--r ----. Know (please read the notes on the back before filling in this page) 4 2553 1 A7 B7 V. Description of the invention () Pass the light source 38a and 38b horizontally forward and backward, and each There is a corresponding identification signal 5 6 in a different direction, so when the characteristic signal of the printing paper 36 is generated, the identification program 54 compares it with the identification signals 5 6 of each direction to judge the printing. The falsification of the paper sheet 36. In addition, in order to increase the recognition ability of the system 30, the sensing mechanism 44 can further add other light sources and sensors to scan different strip-shaped areas on the printed paper sheet 36. 10 When the printed paper 36 passes through the paper feed slot 32, it is printed by the Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs (please read the precautions on the back before filling this page). The test signals 6 2 and 6 4 are in order. It is generated by the sensors 40 a and 40 Id, so there will be a time difference between the two. The sensor signal 62 When 64 and 64 are converted into the characteristic signal 66, the identification program 5 4 will eliminate this time difference so that the difference between the two 15 can correctly constitute the characteristic signal 6 6. Because the sensing signals 6 2 and 6 4 are made of light sources The characteristic curves formed by 3 8 a and 3 8 b after penetrating the long strip-shaped area on the printing paper sheet 36, so the characteristic signal 6 6 represents the difference between the two characteristic curves, that is, printing The difference in the absorption capacity of the 20 strips of strips 3 and 6 on the different wavelengths of the light sources 3 8 a and 3 8 b. As mentioned earlier, the printed paper 3 6 is easily affected by repeated use. Decolorization caused by abrasion, however, this decolorization phenomenon will also affect the sensing signals 6 2 and 6 4 produced by the printing paper 3 6 and make the 2 7 papers fit the medium size (CNS) Λ4 specification.
