INTRODUCTION TO THE INVENTION Field of the Invention The present invention relates to a physical projection device, especially a projection positioning element capable of calibrating a projection position in the physical projection device. BACKGROUND OF THE INVENTION When a physical projection device is conventionally used to enlarge a physical image, the device is usually equipped with a fixed projection table to provide a reference for a user to place a projection range of a projected document or article. The problem often encountered in the operation of such devices is that the documents or objects to be presented cannot be accurately placed in an appropriate position within the projection range of the physical projection device, and the user must refer to the actual image position on the one hand. At the same time, the projected document or article is adjusted passively within the projection range until the appropriate position for projection is found. In particular, when the physical projection device has a zoom-in and zoom-out function, the projection range of the captured physical image is relatively small or larger in inverse proportion. Since the traditional fixed projection table cannot display the change of the calibration projection range, the user must move the position of the projected document or object back and forth in order to find an appropriate projection position. As mentioned above, China's Patent Bulletin No. 4 7 2 1 6 9 and the patent name "physical projection device capable of calibrating the projection position" have addressed the shortcomings of the traditional physical projection device that cannot effectively calibrate the projection range. {Improved device for location. It uses one of the physical projection devices to project the positioning element 10 to calibrate the physical image capture range of one of the physical projection devices, as shown in the first figure. More specifically, the projection positioning elements of the first figure are based on 2 paper sizes that are applicable to the Chinese National Standard (CNS) A4 specification (210X 297 mm) (Please read the precautions on the back before filling and writing this page). · Order · Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 522283 A7 B7 V.

However, the technology disclosed in the above-mentioned patent No. 472 1 69 will still cause considerable application difficulties in actual production. Specifically, in order to effectively calibrate the image capture range of a physical projection device, the projection angles of several light bulbs in the projection positioning element must be adjusted and corrected individually, so that each light bulb can correspondingly mark the corners of the image capture range. . Due to the straight-forward nature of light, each bulb in the projection positioning element must be adjusted to a specific range of projection angles in order to project the light it emits onto a predetermined corner within the image capture range. Therefore, the difficulty in applying the light source to calibrate the image capture range lies in that the forward direction of the light projection is limited to a single path, and the small angular deviation on the light source installation will greatly enlarge the image capture range deviation. For example, when the projection positioning element of a physical projection device is located 40 cm above the projection plane, the relative image capture range is about 30 cm long and 20 cm wide on A4 paper. When the projection angle is 1 When the degree of deviation is high, a calibration position deviation of up to 1 cm will be generated, which will seriously affect the accuracy of the calibration image acquisition range. Therefore, in order to meet the accuracy requirements of a certain calibration and positioning, the projection angle of each light source must be adjusted and corrected one by one during production to control the error of the projection angle within a certain specification range. This will inevitably take a long time and is not in line with mass production. Requirements. On the other hand, a light emitting diode (Light Emitting Diode; LED for short) or a laser light bulb is traditionally used in the above-mentioned projection positioning element ......... f {Please read the back (Please note this page and write this page again) Dimensions · Dimensions The paper size is applicable to the Chinese National Standard (CNS) A4 specification (210X 297). Installing a light-emitting diode within an angle range is prone to the problems of the above-mentioned projection angle control and wiring arrangement, as shown in the second figure. Specifically, taking the second figure as an example, the figure shows a cross-sectional view of a conventional projection positioning element. Generally, there is a circuit board i 4 inside the projection positioning element 10, which is used to provide the power required by the light source 12, Various electronic parts and circuit layouts. Taking the light-emitting diode 12 as an example, due to the required projection angle, each light-emitting diode 12 and the circuit substrate 14 have an acute angle Θ, so that each light-emitting diode 12 cannot be directly installed. It is connected to the circuit substrate 14, and three wires 16 need to be connected between the light emitting diode 12 and the circuit substrate 14. If it is designed to use four independent light-emitting diodes to calibrate the four corners of the image capture range in the projection positioning element, a total of twelve lines are required to connect to the circuit substrate. This will inevitably make the volume inside the projection positioning element Added to accommodate these lines. Moreover, such a design will make it difficult to inevitably affect the projection angle of the installed light-emitting diode when connecting the circuit between the light-emitting diode and the circuit substrate, and increase the difficulty of angle adjustment. As mentioned above, it is very important to improve the projection positioning components of traditional physical projection devices, and to improve the accuracy of the calibration image capture range, so as to effectively improve the operation performance of physical projection devices. Object of the Invention The object of the present invention is to provide a physical projection device capable of calibrating a projection position. 4 This paper size applies to China National Standard (CNS) A4 specification (210X297 mm) (Please read the precautions on the back before filling this page) ^ ........., 玎 ....... .. ^

Different from the conventional projection positioning elements, a plurality of lamps of the light source group 52 are directly connected to the circuit substrate 54 in the projection positioning element 50, respectively, and these bulbs can be laser bulbs or light emitting diodes. More specifically, the light bulbs 52 are soldered to the circuit substrate 54 vertically, and since the light bulbs are directly soldered to the circuit substrate, there is no need to use a wire to connect the light bulbs to the circuit substrate as in the conventional technology, which can reduce The volume of the projection positioning element is troubled by the traditional wire configuration. More importantly, because the bulbs are connected perpendicular to the circuit substrate, in the process of producing the projection positioning component, the step of traditionally adjusting the projection angle of the light source can be omitted. From the perspective of process control, this vertically connected process step is very easy compared to the traditional control of the light source projection angle. Therefore, the projection positioning element of the present invention can shorten the production man-hour and simplify the production process, thereby achieving the objectives of mass production and reduction of production cost. Another feature of the present invention is that the design of the lens group 56 is used to refract the light emitted by the light source group 52. As mentioned above, since the light bulbs in the light source group 52 of the present invention have been vertically connected to the circuit substrate 5 4 ', the light source group 52 of the present invention must refract the light source through the lens group 56 in order to project the light source to the desired Calibration position. It should be noted that traditionally, there are also ways of reflecting light sources with a reflector to achieve the aforementioned purpose of capturing a rare fixed image. However, this method of reflecting light with a mirror still cannot avoid the need to adjust the reflection configured by each light source one by one.

Description of the invention () Mirror reflection angle . Because according to the principle of light reflection, this reflected light basically reflects to the predetermined calibration position is still limited by the single path of the light, so that the reflection angle range of the mirror is still limited to a certain degree of accuracy. Therefore, this method is not The traditional problem of adjusting the projection angle of the light source cannot be effectively solved. And on the other hand, using the principle of reflection will make the mechanism of the projection positioning element increase in the use space ', which will increase the volume of the projection positioning element, which also does not meet the demand for light use of functional elements. In view of the above, please refer to the fifth figure, which shows a lens group in a preferred embodiment of the present invention. The lens group 56 is an annular lens with a triangular cross section. The present invention uses this annular lens to improve the tradition. Problems with components. Specifically, the annular lens 56 in the fifth figure can form the same number of refraction areas 60 outside each light source according to the number and position of the light sources of the light source group 52 in the fourth figure. Each refraction area is located at The outside of each light source is used to refract the light emitted by each light source, so that it accurately refracts the light to several corners of the actual image capture range. The two ends of the A-A section shown in the figure clearly show the triangular section of the annular lens 56. The angle of the inclined plane in this triangular section is based on the design requirements of the light refraction angle and the refractive index of the lens material. It should be noted that the material used to make this toroidal lens is a material that uses a common optical lens, such as an optical acrylic material. In addition, as long as the refractive index of the lens and the angle of the bevel of the triangular section of the lens are determined, the angle required to pass through each of the refraction regions 60 on the annular lens 56 to refract light can be easily achieved. The design can also add a card connected to the projection positioning element body on the outer edge of the ring lens 5 6 This paper size applies to China National Standard (CNS) A4 specifications (210X 297 public variable) (Please read the back first (Notes to fill out this page)
