Description

  The present invention relates to a figure authenticity identification device, and in particular, performs a discrimination process by using a multiple in which a figure image has a difference, and further performs a mechanical operation for controlling the feature of the figure to identify authenticity. The present invention relates to the identification device possessed.

  Currently, with the development of color printing and copying technology of computers, altered prints or reproductions are flooding more and more every day, and it is difficult to identify the authenticity of various designs that have undergone alteration. Securities, national money, etc. can easily deceive the public. With the naked eye, it is not only an error to identify these duplicates, but also the identification speed is too slow, so that it cannot be identified in large quantities and quickly. Therefore, these alterations must be identified by a graphic identification system or device.

  As a conventional true / false identification system for figures, a numeric line video comparison system is provided, which uses a 3D scanning lens to capture the banknote's anti-counterfeiting figures and compares the line video, There is one that can authenticate authenticity (see, for example, Patent Document 1).

In addition, as a system for identifying authenticity of figures in the past, it uses the printing technology at specific positions of the figure, the distribution of color notation, and the characteristics of the image of the fiber material to expand the characteristics of the above image to a multiple that has a difference from the forged image. In some cases, the discrimination processing can be performed (see, for example, Patent Document 2).
Republic of China Recruitment Bulletin No. 490054 Republic of China Recruitment Bulletin No. 564377

  In the conventional figure authenticity identification system as described above, the comparison of the money number line image by preventing counterfeiting of the banknote is based on the design of the anticounterfeiting characteristic of the banknote (shape and pattern of the money number) and the type of banknote ( Limited by different national standards, size by different amount). Once the money has been revised, the old version of the identification system or device cannot be used again, resulting in a waste of resources. In addition, the comparison of the line images of the above-mentioned forgery-preventing monetary numbers has the following problems, and the longer the bills are used, the more severe the color fade of the printing ink becomes. There is a problem that misjudgment occurs, and further, the 3D scanning lens is susceptible to interference from outside light, ultraviolet black lamp light, or watermark measurement lamp, thereby reducing the accuracy of identification. It was.

  In addition, in the conventional graphic authenticity identification system as described above, since the anti-counterfeiting feature is not installed in general public documents and certificates, the conventional graphic authenticity identification system does not provide anti-counterfeiting. Can be applied only to banknotes and securities with features (watermarks, letterpress printing, anti-counterfeiting lines, discolored ink, fluorescent designs, laser designs), student certificates and birth certificates stamped only with dry stamps It is not applicable to. For this reason, since a general educational certificate or birth certificate can only identify a dry stamp, there is a problem that inconvenience occurs in authenticity identification. Furthermore, discolored ink or fluorescent radiation can be easily altered or counterfeited and difficult to identify with the naked eye. If a device is used to identify authenticity, the longer the bill is used, the longer the bill is used, the more severe the loss caused by the friction between the discolored ink and the fluorescent light. There was a problem that it was.

  In fact, money, securities, general public documents or certificates still have general differences such as printing technology, color distribution, and fiber materials. False can be identified. Even though color printing and copying technology are constantly evolving, the above differences exist between authenticity. Therefore, in a state where a general public document or certificate does not have a forgery prevention feature, these differences are sufficient for authenticity identification. In addition, credit cards, banknotes, and securities with anti-counterfeiting features also have general differences in printing technology, color distribution, fiber materials, etc. And can be applied to authenticity identification. In other words, the inspection of falsified products or copy products does not necessarily have to use anti-counterfeiting features, but can accurately identify authenticity using differences in printing technology, color distribution, fiber material, etc. be able to.

  However, in the conventional method of discrimination processing by the graphics authenticity identification system, if it is not performed in combination with a mechanical or electrical operation mechanism, the mechanical operation of the true / false discrimination by the feature of the graphics can be completed. Therefore, the general structure of the mechanism has a problem that it cannot meet general demand unless the operation procedure is reduced, the structure is simplified, and the identification accuracy is not increased. For this reason, it is necessary to further improve the conventional graphic authenticity identification system as described above.

By forming the transport device 10 so as to be positioned around the mounting table 1, it is possible to transport the identification article a and pass through the mounting table a. The transport device 10 includes a flip roller set 11 and a conveyor 12. The flip roller set 11 is composed of a roller type flipper and can elastically rotate to a certain adjustment angle depending on the quantity of the identification object a or the stacked thickness. It is possible to hold the contact with the identified article a. The flip roller set 11 can be used for the identification articles a to enter the entrance 2 one by one in order. The conveyor 12 is fitted to a roller set and is driven to rotate by a power member (not shown), and is further configured to be transported between the inlet 2 and the outlet 3. The identification article a is transported to a specific position by the conveyor 12, and the photographing operation is performed by the light source device 20 and the camera lens set 30, and then the identification procedure is performed by the programmable identification element 50. Transport a to outlet 3.

  Referring to FIGS. 2 and 3 again, the light source device 20 irradiates the identification object a using a specific light source. Specific light sources of the light source device 20 include light emitting diodes such as red, green, blue, infrared, and ultraviolet light, laser diodes, and other light sources having a specific wavelength range. The camera lens set 30 belongs to a controllable magnifying lens, and an optical magnifying device (not shown) is arranged, so that the feature of the figure can be enlarged to a predetermined multiple.
