The present invention relates to securities (BILL) data used in vending machines or coin exchanges, and more particularly, LED packages that emit various wavelengths of a strong pulse of light through the securities, and a strong pulsed light as a test zone of the securities. High precision using collimator lens for aiming at various wavelengths and photodiode receiving light passing through the security to compare with preset reference value by the internal microcontroller of the securities valley data to verify the authenticity of the security. It is about securities valley data.

With the rapid development of technology, life forms have changed. Various vending machines (card dispensers, ticket machines, coin changers, etc.) are used everywhere to sell multiple products without servicemen. These vending machines save labor and provide convenience to people. The coin exchanger of the vending machine stores coins and bills.

However, sellers and consumers are always attacked by the problem of counterfeit bills due to the use of paper money. With the rapid development of computer technology, it is possible to print bills by scanning them with a computer. Therefore, money has anti-counterfeiting technology. Visible anti-counterfeiting technologies include visually identifiable paper materials, inks, seals, covers, and the like. However, invisible anti-counterfeiting technologies require special instruments or tools to prove their authenticity. For this purpose, the validity data were detected using a roller holding the banknote inserted above the magnetic head, detecting the emblem and the portrait magnetic ink, and each preset reference value to determine the authenticity of the banknote according to the comparison value. Compare the signals. However, the magnetic head is likely to be contaminated by ink dust, which may result in inaccurate detection. Moreover, counterfeit bill manufacturers make counterfeit bills containing similar magnetic inks to trick machines.

Today's oil-blinded valleys typically use different light emitting diodes (LEDs) to emit different light to examine the properties of different bills. 11 and 12 illustrate conventional bill valley data. The design of the securities valley data includes a plurality of photo sensors installed between the first linear light source A1 and the second linear light source A2 and the two linear light sources A1 and A2 disposed obliquely on both sides of the test zone F1. C1 and a first optical element B1 provided below the photo sensor C1. When the document (securities) E1 enters the entrance of the securities valley data, the entrance is blocked and the sheet conveying roller set is driven to move the document (securities) E1 through the test zone F1. At the same time, the linear light sources A1 and A2 are controlled to emit pulsed light on the document (securities) E1, the first optical element B1 condenses the reflected light on the photo sensor C1, and the photo sensor ( C1) feeds back the detection value at a predetermined cyclic time point. This detection value is an indication of the average paired-pulse facilitation (PPF) of the scanned surface color of the document (securities) E1. The above method allows the entire document (securities) to be examined. In addition, the auxiliary light source A4 and the fourth optical device B4 may be provided on the other side. The auxiliary light source A4 is controlled to emit the transmitted light passing through the document (the securities) E1 to check the transmission of the document (the securities) E1. After scanning, the operating unit of the securities validator receives several values generated by several light sources and compares the values with the stored reference values to determine whether to accept or reject the document (securities) E1. . According to this derivation method, it is necessary to verify the multiple strip blocks of the document (securities) E1 and to compare the reference values with the scan values generated by the strip blocks for more careful decisions. According to this scheme, each linear light source A1 or A2 uses different colored light emitting diodes (LEDs) A3 to emit different colors of light for demonstration. Moreover, the second photon B2 and the third optical element B3 are set in front of the first linear light source A1 and the second linear light source A2 to correct the respective light source output angles. The arrangement of the linear light sources A1, A2, the optical elements B1, B2, B3 and the photo sensor C1 must be carefully calculated and the concealment signal can be compared with a reference value for a more accurate determination.

The above-described conventional securities valley data has a number of disadvantages.

1. In each linear light source (A1 or A2), the LEDs are spaced apart from each other by a predetermined distance, so this LED (A3) has the same test zone (F1) in which the documents (securities) E1 are of different colors ), We simply use the average of all scanned steels to calculate the surface chromatic reaction of the document (securities) (E1).

2. Different documents (securities) from different countries (E1) have different anti-counterfeiting characteristics. Therefore, the main unit must be equipped with a high capacity database to store preset reference values for comparison.

3. This verification method reflects from the various strip blocks of the document (securities) E1 to compare the reference value with the light emitting diodes A3 for emitting various colors of light onto the document (securities) E1. The photo sensor C1 having the first optical element B1 is used to collect the light. The precision of adjustment between the light emitting diode A3, the photo sensor C1 and the optical elements B1, B2, B3 is important.

4. After scanning the various strip blocks of the document (securities) E1 from the light emitting diodes A3 with different colors of light, a precise array calculation procedure is necessary to prove the authenticity of the document (securities) E1. Do. This calculation procedure takes some time and is not suitable for use in vending machines to verify the authenticity of bills.

5. The complex structure of the securities valley data design uses many parts and increases manufacturing costs.

Moreover, Auto Teller Machine (ATM) or bill counts used in banking systems typically use infrared lamps to scan bills. Infrared lamps are not suitable for use in bill validators for vending machines. Infrared lamp type bill validators are used in external vending machines, where air moisture penetrates through the gap between the lamp bulb and the electrical socket, creating a circuit short. Moreover, infrared lamps consume a lot of power and generate a lot of thermal energy during operation. Moreover, infrared lamps are big in size, have a short durability life and are prone to breakage.

The present invention is to overcome the above-mentioned conventional problems, the object of the present invention is to be used in a vending machine or a coin exchanger, a strong pulsed light in one same position on the test securities to emit several wavelengths To provide the validity of the LED package and securities validation using a corresponding photodiode to receive light passing through the test securities to determine the authenticity of the test securities. Such devices overcome the complex securities authenticity determination process of prior art designs using multiple LEDs and photo sensors. Therefore, the present invention requires a small installation space in the automatic vending machine or coin exchanger, and saves the installation cost.

It is another object of the present invention to provide securities valley data using one LED package, one collimator lens, one condenser lens and one diode to configure the securities validation unit to accurately determine the authenticity of the securities. This design suffers from the complexity of conventional techniques using multiple light emitting diodes for test securities to scan different test zones, optical elements for collecting the light scanned onto the photo sensor, and multiple optical elements for modifying the light source output angle. To overcome. Moreover, the design of the securities validator of the present invention has the advantages of no need of lamp warning time, fast operating speed, small size, low power consumption, low pollution, high brightness and long durability life.

Hereinafter, embodiments of the present invention will be described. Before explaining the features of the present invention, it is necessary to understand the physical properties of the light. The colors of the known light rays include red, yellow, green, blue, indigo and purple. Light beams of different colors have different wavelengths. When radiating different colored light rays onto an object, different transmission and refraction indices are obtained. For example, when irradiating light onto a red colored object, the red colored object will reflect the light of the red color and absorb light of another color, so that only the red light is visible. When irradiating light of different colors to an object, the light density of light of different colors passing through the object is weaker than red light, since red light has the highest transmission rate. The present invention is used for the demonstration of securities using the physical properties of light described above. Moreover, since light of various wavelengths has various colors, the following description of the present invention uses the wavelength for explanation.

When the security 5 is inserted into the insertion slot 111, it is delivered by the delivery unit 11 through the delivery passage 112 (the delivery unit 11 is known and not within the scope of the present invention, in this respect More details are omitted). At this time, the internal microcontroller 2 of the securities valley data 1 outputs the digital start signal to the digital / analog converter 3 so as to convert the digital start signal into an analog start signal, and converts the analog start signal into a light emitting module. The LED package 121 is sent to the LED package 121 to cause the LED package 121 to emit various wavelengths of strong pulsed light toward the collimator lens 122. When a strong pulsed light passes from the LED package 121 through the collimator lens 122, the collimator lens 122 is directed to the collimator beam going through the shape and the predetermined area of the test zone 51 of the security (5). The strong pulsed light is made parallel (see FIGS. 4 and 4A). After passing through the test zone 51 of the securities 5, the collimating light beam goes to the condenser lens 131 and is focused on the photodiode 132 by the condenser lens 131 to the amplifier 4 for amplification.
