Description

  The present invention relates to a kind of securities identification device. In particular, a light emitting diode component capable of emitting different wavelengths and a first lens capable of directing and emitting light in parallel are installed in an identification device installed in a kind of vending machine or money changer, whereby the light emitting diode components emit differently. A pulse with a wavelength is irradiated as a parallel beam onto the surface of the securities, and a parallel parallel light is generated on the opposite surface of the securities, and a fixed area and a shape receiving area is formed on the securities surface. Microcontroller inside the securities identification device compares and contrasts the penetrating parallel light with a predetermined reference value, identifies the authenticity of securities, and identifies securities with functions and effects that improve the identification rate and accuracy of securities. Related to the device.

With the development of science and technology, the importance of convenience and speed has become important in the modern society, so vending machines (card vending machines, ticket vending machines, glaciers) Etc.) are installed. Vending machines can greatly reduce labor costs, and their convenience should be welcomed by modern people. Two types of coins and banknotes are used in the current vending machine.
However, forgery of banknotes has emerged as a new problem as merchandise distribution and currency exchange become possible. Advances in computer technology have led to an increase in the number of banknotes that are counterfeited by skillfully using scanners, copiers, printers, etc. Therefore, many of the banknotes currently in circulation have various anti-counterfeit technologies. Anti-counterfeiting measures include materials, ink, and graphic parts that are easy for consumers to identify. The invisible parts are not visible to the naked eye and must be identified using equipment. .
A general banknote discriminator reads a banknote with a roller, scans it with a magnetic head centering on the long axis of a banknote, and produces a special symbol in the emblem design on a banknote and the magnetic ink of the portrait center. Thereby, a bill discriminator contrasts this special symbol and a reference value table alternately, and judges the face value and authenticity of a bill. However, in this structure, since the magnetic head is contaminated by the ink peeling, it is often necessary to perform maintenance. Moreover, counterfeit banknote manufacturers are also trying to deceive the banknote identification machine by printing "banknotes" with a printer equipped with magnetic ink.

Therefore, as shown in FIGS. 14 and 15, some current banknote discriminators use different light emitting diodes to generate different light beams and identify the characteristics of various banknotes. The banknote discriminator is provided with first and second linear light sources A1 and A2 arranged in a linear manner above both sides of the internal measurement area F1. A plurality of photosensitive devices C1 are installed at intermediate portions corresponding to the first and second linear light sources A1 and A2 on both sides.
When the identification document E1 enters the banknote identification opening, the light beam from the cave is blocked and the roller D1 is activated. When the identification document E1 enters the bill validator and passes through the measurement area F1, the first and second linear light sources A1 and A2 installed above both sides of the identification document E1 receive continuous short pulses to the measurement object. Irradiation and reflected light reflected through the first optical component B1 installed in front of the photoconductor C1 is received. Further, the sensed numerical value is transferred based on a specified time. The numerical value represents an average light amount of the color of the surface of the identification document E1 sensed by the lit measurement area F1, and thus the entire document is inspected.
Further, the fourth optical component B4 that emits the attached light source A4 having a high penetration rate is installed on the opposite side of the identification document E1 to correspond to the penetration rate of the identification document E1. Thus, after the bill discriminator completes the inspection of the identification document E1, the arithmetic unit in the bill discriminator receives a numerical value emitted by a different light source, compares it with a stored reference numerical value, and decides whether to accept or reject it. .

However, this type of sensing method requires a lot of bar-like strip blocks on each part of the identification document E1, and it is necessary to contrast with the strip-like block reference value table stored in the main body in advance. Through accurate array calculation, it is possible to identify for the first time whether or not each band block value on the identification document E1 is accurate.
In addition, in this type of sensing method, it is necessary to install a large number of light emitting diodes A3 in the first and second linear light sources A1 and A2 above both sides of the measurement area F1 to emit inspection light of different colors. It is necessary to install the second optical component B2 and the third optical component B3 in front of the first and second linear light sources A1 and A2 and to adjust the angle of the light source output.
Further, the reflected light reflected by the identification document E1 also needs to concentrate the reflected light in the photoconductor C1 through the first optical component B1, so that the first and second linear light sources A1 and A2 and the photoconductor C1. The optical components B1, B2, and B3 to which the three members correspond require sufficiently precise calculation and arrangement. Otherwise, it is impossible to accurately compare and contrast with the band-shaped block reference value stored in the main body in advance.

The known structure has the following drawbacks.
1. There is a section of a certain distance between the plurality of light emitting diodes A3 in the first linear light source A1, but in this type of inspection method, the identification document E1 can be identified by different light sources in the same measurement area F1. First, it is only possible to calculate the color reaction of the surface of the banknote by the average value of the received light.
2. Since the identification documents E1 with different monetary values and different face values in each country have their own characteristics, it is necessary to store a very large number of values in the main body database in advance. A comparison can be made to the block position.
3. This kind of sensing system confirms the irradiation angle of the light beam through the reflection system of the light emitting diode A3, and receives the reflected light reflected by the photosensitive device C1 through the corresponding first optical component B1, and thus on the identification document E1. Therefore, a high accuracy is required for adjustment between the light emitting diode A3, the photosensitive device C1, and the optical components B1, B2, and B3.
4). After the light emitting diode A3 irradiates each band block on the identification document E1, it is necessary to perform a very precise array calculation, otherwise the authenticity of the identification document E1 cannot be confirmed. For this reason, the time spent is very long and cannot be applied to the vending machine which receives a banknote immediately.
5. This type of identification system requires precise equipment, its overall structure is too complicated, and there are relatively many components, resulting in increased costs in manufacturing and assembly.

On the other hand, most of ATMs or banknote counters used in bank systems that require immediate identification employ ultraviolet irradiation. However, the ultraviolet irradiation method cannot be applied to a bill validator used for an outdoor vending machine. This is because the vending machine has a high risk of incurring moisture or water when it rains due to poor sealing of the lighthouse, causing a short-circuit of the lamp tube. In addition, lamp tubes usually tend to fade after a certain period of time, so this kind of lamp tube has a fast light decay, high power consumption, high heat generation, short life and short breakage. It has disadvantages such as difficulty in collection. Furthermore, since the lamp tube has a relatively large area, it cannot be applied to a banknote receiving machine in a limited space of a vending machine.
For this reason, it has been difficult to provide the banknote receiving machine in the vending machine with an accurate identification capability, and there have been no constant cases of fake bill exchange through the vending machine.

Therefore, the stability of securities authenticity identification is expanded, the securities identification rate is improved, and the accuracy is improved.

In order to help understanding of the characteristics of the present invention, the physical characteristics of the light beam will be briefly described here.
Commonly known light colors are approximately red, orange, yellow, green, indigo, blue, purple, and the like. Because different color rays have different wavelengths, when an object with a different color ray is illuminated, the ray exhibits different penetration and reflectance than other color rays. For example, when a light ray is illuminated on a red object, red light in the spectrum is reflected and transmitted to the object, other colors of light are absorbed by the object, and we can see red. Further, when an object with a red light beam is irradiated, as is clear from the comparison between the red light and the other light beam, the red light has the strongest penetration rate, and therefore the light beam of another color is irradiated onto the object. Then, the light beam that the object transmits is weaker than the red light. The present invention applies the above-mentioned characteristics of light to identification of securities.
Hereinafter, since the light beams having different wavelengths indicate different colors of the light beams, the wavelength of the light beam will be described in detail in the preferred embodiment of the securities identifying device of the present invention.

The securities identification device 1 of the present invention includes a transfer device 11, a light source module 12, a light source light receiving module 13, an anti-theft gate 14, and an anti-theft lock 15 as shown in FIG.
The transfer device 11 includes a bill insertion slot 111 into which securities are inserted, and a transfer passage 112 for sending the securities into the identification device 1.
The light source module 12 is installed above the transfer passage 112, and the light source module 12 further includes a light emitting diode component 121 that can emit different wavelengths and a first lens 122 that receives light emitted from the light emitting diode component 121. Install.
The light source light receiving module 13 is installed below the transfer passage 112 and the light source light receiving module 13 further receives the second lens 131 and the second lens 131 that receive a light beam penetrating from the plane of the transfer passage 112. A photodiode 132 that can collect light is installed. As shown in FIG. 2, the light emitting diode component 121 is connected to the microcontroller 2 and the analog / digital converter (converter) 3, and the photoelectric diode 132 is connected to the microcontroller 2 from the enlarger (amplifier) 4. Yes.
The anti-theft gate 14 is installed at the end of the transfer passage 112, and an anti-theft lock 15 is installed on one side of the anti-theft gate 14. The anti-theft gate 14 and the anti-theft lock 15 form an anti-theft device in the identification device 1.

Further, as shown in FIG. 2 which is a block chart of the identification system, FIG. 4 which is an instruction diagram of securities identification, and FIG. 1, the securities identification apparatus of the present invention is applied to a general vending machine or a change machine. Applied.
First, the securities 5 are inserted from the banknote slot 111, and the securities 5 are sent into the identification device 1 through the transfer passage 112 installed inside the transfer device 11. At this time, the microcontroller 2 in the identification device 1 sends a digital activation signal to an analog / digital converter (converter) 3, which converts the digital activation signal into an analog signal, When sent to the light emitting diode part 121, the light emitting diode part 121 continuously emits pulses of different wavelengths.
When these pulses pass through the first lens 122, the pulses become parallel beams and irradiate the surface of the securities 5 to form a measurement area 51 having a fixed area and shape (see FIGS. 4 and 5). Parallel light that penetrates is generated on the opposite surface of the securities 5, and the parallel light that has penetrated further passes through the second lens 131, and the parallel light that has penetrated by the second lens 131 passes through the photodiode 132. Concentrated.
Further, the signal collected by the photo diode 132 is transferred to the amplifying (amplifying) unit 4, the signal is expanded or increased, and transferred to the microcontroller 2. The figure and intensity distribution output by the signal are shown in FIG. 5 which is an indication diagram of the output light field and FIG. 6 which is an intensity distribution diagram of the output light field (the horizontal axis is the position of the securities 5 and the vertical axis is the light receiving unit). Light quantity (unitless by measuring instrument)).
Finally, the microcontroller 2 or a control unit installed in advance compares the internal reference value with the characteristics of the parallel light collected by the photodiode 132, and analyzes the authenticity of the securities 5.

  Further, as shown in FIG. 7, the present invention includes the light emitting diode parts 121 and 121a, the first lenses 122 and 122a, the second lenses 131 and 131a, the photodiodes 132 and 132a, and the measurement areas 51 and 51a. Assume that the parts operated by the securities identification device form a linear relative relationship. To put it simply, since the arrangement of the components is on the positions of the homologous axes 6, 6a, the light emitting diode component 121 uses a light emitting diode chip encapsulated therein to have different wavelengths due to the linear relationship formed by the components. The measurement area 51 having a fixed area and a shape can be formed on the surface of the securities 5 that are separated by a predetermined position. Therefore, when the identification device 1 identifies the securities 5, the measurement areas 51 and 51a formed on the securities 5 are not repeatedly detected, and other adjacent light emitting diode components (121a, etc.) ) Pulse interference.

There are the following judgment methods for judging the authenticity of all the securities 5 by the light emitting diode parts 121 of the light source module 12.
The first type is a method for discriminating the paper quality of the securities 5. When the securities 5 are irradiated with the light emitting diode parts 121 at different wavelengths, the measurement areas 51 in which the securities 5 are generated show different penetration rates, and therefore the measurement areas 51 corresponding to the securities 5 have different intensities. Generate a light source. Therefore, the microcontroller 2 compares and contrasts the light sources having different intensities with predetermined values, and determines the authenticity of the securities 5.
Furthermore, another system uses the color of the securities 5 themselves or the pattern color on the securities 5 to filter different light rays emitted from the light-emitting diode parts 121. The microcontroller 2 compares and contrasts the light beam penetrating the securities 5 with a predetermined value of the microcontroller 2 or a predetermined control unit, and judges the authenticity of the securities 5.

The light emitting diode component 121 of the light source module 12 uses a module as shown in FIGS. For example, as shown in FIG. Green. IR850. Red. It is a light source module incorporating light emitting diodes of 5 colors having a total of 5 chips of IR940 (5 colors in total). As another light source module, as shown in FIG. 9, the light source diode controls the light amount. For example, in the five color light emitting diodes of FIG. Select which color to turn on or off. Further, as another light source module, as shown in FIG. 10, for example, a module for controlling light emitting diodes of five colors in the module of FIG. 9 may be used. Or the light emitting diode of five colors as a whole is selected to emit light. In addition, there are a total of nine five-color light emitting diodes in the wiring of FIG. 10, and the function of the unit (U2) is to select X (1-5) of nine five-color light emitting diodes. The function U3) corresponds to the wiring shown in FIG. 9 and controls the brightness of the five light emitting diodes of the five color light emitting diodes.
Further, a circuit diagram of the module of the analog / digital converter (converter) 3 is shown in FIG. 11. This module controls the luminance of each of the five light emitting diodes, and corresponds to the operation of the module of FIG. To do. Similarly, the circuit diagram of the photodiode 132 provided separately in the light source light receiving module 13 is shown in FIG. 12, but the module having the blank card unnecessary reception enlarged circuit diagram corresponds to the digital register in FIG. Amplifies the current reception signal. FIG. 13 is a circuit diagram of the blank card calibration unnecessary expansion (amplifier) 4 in the digital register, which is provided in the light source light receiving module 13.

One of the features of the present invention is to irradiate the same position of the securities 5 with light beams of different wavelengths emitted from the light-emitting diode chips inside the light-emitting diode parts 121, thereby reading the authenticity of the securities 5. It is. In addition, through the combination of the first lens 122 and the securities 5, the securities identification apparatus according to the embodiment of the present invention can perform measurement using pulses of different wavelengths at the same position on the surface of the securities 5. Furthermore, it is not necessary to correct the output angle of the light source by using optical components opposed to a large number of sets of light emitting diodes. Therefore, the present invention can reduce the cost and increase the identification accuracy.
The advantages of pulses of different wavelengths emitted by the light emitting diode component 121 are that it does not generate heat like conventional lighting and light, has a fast reaction speed, small volume, low power consumption, low pollution, high brightness, and long life. Therefore, the present invention can be applied to a vending machine or a change machine with a limited space. Through this kind of structural design and identification method, the stability of securities authenticity identification is expanded, the securities identification rate is improved, and the accuracy is improved.

FIG. 3, which is an operation flowchart of light source identification of the securities identification device of the present invention, will be described with reference to FIG. 4, which is an instruction diagram of securities identification of the present invention.

In the above description, in order to emit pulses having different wavelengths depending on the light emitting diode component 121 to be operated, the light emitting diode component 121 encloses light emitting diode chips having five different wavelengths. The light emitting diode chip has a wavelength of 615 nm to 635 nm red light, 515 nm to 532 nm green light, 460 nm to 475 nm blue light, and 850 nm first infrared light with stronger penetrating power, 940 nm second infrared light or ultraviolet light. Divided into light.
These light emitting diode chips are encapsulated in one module, and thus the light emitting diode component 121 emits pulses of different wavelengths at the same position, which is an equivalent range of the securities identification device of the present invention. Needless to say, the present invention includes all of the bright colors and structural changes with the same effect.
Furthermore, the securities used in the above description are securities such as banknotes, alternative banknotes, traveler's checks, or securities, and it is a matter of course that this kind of simple color change and operational change of equivalent effect are all included in the present invention. is there.

Costs can be reduced and the volume it occupies can be reduced.
In addition, since the light emitting diode emits a light source with a light emitting diode in the securities receiving machine and the volume occupied by the light emitting diode chip enclosed in the light emitting diode is small, it can also be used in a securities receiving machine with limited space for vending machines or money changers. Applicable.
In addition, the overall components are simple, and by combining the first lens, there is no need to adjust the light irradiation angle precisely. Furthermore, the light emitting diode does not generate heat like conventional lighting and lights, and the reaction speed Has characteristics such as high speed, low power consumption, low pollution, high brightness, long life, etc., so that the stability of securities authenticity identification is expanded, the security identification rate is improved, and the accuracy is increased.

Furthermore, since the reflected light emitted by the identification document also had to be concentrated in the photoconductor through the optical components, the light emitting diode, photosensor, and the optical components to which both corresponded required very precise calculation and arrangement. . On the other hand, in the present invention, since the light emitting diode component and the photoelectric diode emit and receive the light source by the opposed lenses, the accuracy of production of the identification system and installation in the vending machine or the change machine is improved. Parts purchase cost can be reduced.
3. In the present invention, pulses with different wavelengths are emitted from the light emitting diodes to the securities to detect them. However, since the volume of the light emitting diodes is small, the vending machine or the money changer also has a limited space in the securities receiving machine.
