Description

200823806 IX. Description of the Invention: [Technical Field] The present invention provides a valuable certificate identification device which is mainly provided with a different wavelength for the identification device provided by the preset vending machine or the coin machine (10). The light-emitting diode element and the first lens capable of guiding the light source to be parallelly emitted, so that the pulse light of different wavelengths emitted by the light-emitting diode element will be irradiated on the surface of the strip with a parallel beam' and is valuable The other side of the certificate--the surface produces a penetrating parallel light, and forms a field with a fine area of fine-grained shape in the price of the wire, so the valuable part of the certificate identification part can be penetrated Parallel wire preset reference values are compared to 'use this to match the price of the securities and improve the identification rate and accuracy of the valuable securities. * [Prior Art] According to the 'Current Social Technology Materials' in the public places in Xuxiang, in order to consider the convenience and speed of modern people, there are automated vendors # machines (such as card machines, ticket machines or banknote machines). ), by automating the sale of machines, not only can people save a lot of money, but their convenience is more acceptable to modern people. At present, the automatic vending machine uses two methods of coin and banknote receiver structure. However, since the circulation of goods and currency exchange, counterfeit banknotes have been a headache for businesses and consumers, and with the advancement of computer technology, some unscrupulous people can use computers to scan, copy and print from the market. The real banknotes are copied. Therefore, the real banknotes circulating in the market of Mesh 1 are designed with various banknote anti-counterfeiting technologies, such as banknotes =, ·, , and employees. , the image part, so that the consumer car six easy to enter 5 200823806 λ a ^ identification part is unable to age shun, the need for the machine or the instrument 'machine is to use the roller to read the banknotes, and then the magnetic banknotes long axis The center brushed, so that the heraldic pattern on the banknote and the magnetic in the center of the portrait!·The oil-and-soil-dissipating μ, let the miscellaneous machine interact with the list of the special notes, and, in order to judge the denomination and authenticity of the banknote. But because the head will peel off due to ink

It’s more than ten secrets, and counterfeit banknote makers use photocopiers with magnetic inks to copy “banknotes” and trick money detectors. However, in today's money detectors, there are kinds of _ not _ light-emitting diodes to generate different rules to check the characteristics of various types of banknotes, please refer to the tenth and twelve figures. The money detector is arranged above the two sides of the internal measured _fi with the first and second linear light sources A i Μ 2 arranged in a linear manner, and the first -, - linear light sources and the eight sides on the - side The corresponding intermediate part is provided with a plurality of photosensitive SC1, so when the identification text i enters the counter of the money detector, the system of the hole is intercepted, and the identification file E i enters the money detector. When passing through the measured area F i , the first and second linear light sources A 1 and a 2 disposed above the two sides of the identification file E i are _ continuous short pulses to illuminate the test object and pass through the photosensitive HC1. The first optical component B i is arranged to receive the reflected scattered light and pass back to the side value of the specified cycle _, which represents the recognized postal surface of the illuminated __丨The average amount of light in the color of the body, the square wire Wei New, please, in the identification file EU-_ can be set to emit „Scale Di _ light 4 with 6 200823806 λ " ' 1 and 4 optical components Β 4, to check the identification file Ε 2 penetration rate, by borrowing, the money detector to view the finished file Ε Μ, Wei bank shooting unit will It will receive the values generated by different light sources and compare them with the reference values of the age to decide whether to accept or exit L. The sensing mode is divided into a plurality of strip-shaped blocks on each part of the identification file E i . And the pre-stored strip-shaped block reference value list parent-child's re-transmission is very precise, in order to compare whether the value of each strip-shaped block on the identification file E1 is correct, and the sensing method is not only It is necessary to provide a large amount of light-distributing A 3 in the first and second linear light sources A i and the person 2 above the two sides of the X-measuring area F1 to emit non-color detecting light, and in the first-, --linear filament A 1 and A 2 is also provided with a second optical element B 2 and a third optical element B 3 to correct the angle of the light source output. Furthermore, the scattered light reflected by the identification file E1 also needs to pass through a first optical element B. Work to concentrate the scattered light in the sensitized |§ C 1 , so the first line The light source ai, the second linear light source φ A2 and the photoreceptor C1 and the optical components B1, B2 and B3 corresponding to the three need to be very precise calculation and arrangement, so that the reference value of the strip-shaped block of the human domain can be read first. A correct list comparison. Therefore, the flow of this type of banknote verification method is not only complicated, but still has the following defects: 1. Since there is a 之间 between the plurality of light-emitting diodes a 3 inside the first linear light source A 1 The distance between the distances is such that the verification method cannot verify that the identification file £1 is the same as the measured area F1 with different light, and only the average value of the measured light of 200823806 can be used to calculate the surface color reaction of the banknote. Each country has an identification file E1 of different currency values. The identification files of different denominations have their own characteristics, so the host must pre-store a very large data database to be able to access all the strips on the various identification files E i . The position is compared. 3. In this way, the money-checking type uses the light-emitting diode a 3 to refract the light-illuminating limb ' and the light-transmitting element B 1 to receive the reflected scattered light. The position of each block on the touch file E 1 is compared, so the adjustment between the diode A 3 , the sensor c 丄 and the optical elements B1 , b 2 and B 3 is very precise. 4. After the LED A3_ identifies the strips on the file E1, it needs to perform very precise array calculations to confirm the authenticity of the identification file E i. The time spent is also long, so it is not suitable. The department receives a vending machine such as a banknote. The equipment required for this type of inspection is more sophisticated, and its overall construction is still somewhat complicated and components, resulting in an overall cost increase during manufacturing and assembly. In addition, it is necessary to (4) touch the secrets of the company, so that the machine or the banknotes are all irradiated with the material line lamp. This type of ultraviolet lamp cannot be applied to the banknote receiver used by the outdoor machine. The vending machine is easy to cause the water vapor or water to infiltrate due to the poor sealing of the lamp holder. When the lamp is burned, and the lamp is usually used, it is often prone to exhaustion after a period of time. 8 200823806 The tube still has fast light attenuation, high power consumption, and the product is not easy to recycle _, and the __ product is large, straight: wide, fragile and ground identification ability, the secret wealth is from __ lag, so, f He Tong collapsed _ lost, the straightforward of the cash bank, the increase of paper _ the error of the machine and the application of Lang limited paper
