It is worth noting that the amount of light received by the charge coupling element is closely related to the speed at which the scanning light machine 56 moves, that is, the faster the scanning light machine 56 moves, the more light the charge coupling element receives in a unit time. It must be improved to maintain its higher image resolution. FIG. 2 is a schematic structural diagram of a conventional dual-light source module. Please refer to Figure 2. Generally, scanning in large size (such as A3 size) and high-speed scanning (15 ~ ^ Oppm) will use a dual-light source module to provide charge-coupled components (not shown) in the same area.

Among them, the dual light sources ·, the projected light beams 112a, 112b will pass through a glass platform 52 and be projected on a scanning object, 60 ', and the dual light sources UGa, U () b will be projected onto the scanning object. U2a and U2b will have a partially overlapping area, and a part of the light beam reflected from this knife heavy area 62 will pass through the slot 128 of the fixed lamp frame and enter the scanning light machine (not shown). As mentioned above, when the conventional scanner scans at a low speed (3 to 4 variations), the above-mentioned partial light beam 4 reflected from the partially overlapping area 62 can still increase the amount of light emitted by the power supply hybrid element. However, during high-speed scanning, the above-mentioned part of the beam 114 cannot provide sufficient incidence of the charged surface-contact element. 1242361 14274twf.doc / 006 The frame can only be applied to a single rule :: good. In addition, if you use a fixed lamp, you need to re-produce another scanner that is not cheap for other specifications. & The light intensity of the human light source and the light intensity are variable.

In the above-mentioned adjustable light source module 2000, the light frame rotating structure 226 includes, for example, a main bracket 226a and a control board. 226b. Among them, the main bracket 226a is fixed on the scanning light machine and is connected to both ends of the first lamp bracket 222 and the second lamp bracket 224. Moreover, the main bracket 22 is relative to the adjustable lamp brackets 222 and 224, as described above. For example, a groove 227 is provided. In addition, the control board 226b is arranged in the groove 227 and can be moved in the groove 227, so that the adjustable lamp frames 222 and 224 are rotated by the relative displacement of the control board 226b. 0 In a preferred embodiment of the present invention, for example, the main bracket 226a further has a slot 228 exposed between the first lamp holder 222 and the second lamp holder 224, and a part of the light beam (not shown) reflected from the partially overlapping area 82 Y will pass through this slot 228 and be incident into the scanning light machine. In addition, the control board 22 is moved into the groove 227 by an adjusting screw 232, for example. The adjusting screw flange ⑽ can be locked to the main support 6a, for example, and the adjusting screw tap can be fixed to the control board 226b by a buckle-ring 234, for example. In addition, the control board 226b has, for example, a positioning hole 236, and the above-mentioned adjustable lamp frame pull, ^, for example, has a positioning tip 238, which is inserted into the positioning hole 236 and moves to the positioning hole 236 so that The adjustable lamp frames 222 and 224 are rotated. Figures 5A and 5B show the adjustable lamp source mode described in the first embodiment of the present invention. Please refer to 5A and FIG. 5B at the same time. First, as shown in FIG. 5A, the financial control board 2 is movably arranged in the groove 227 so that the adjustable light stands 222, 224 can be controlled by 12 1242361 14274twf. .doc / 006, the relative displacement of 226b and an angle θ. In more detail, in this embodiment, for example, the control board dove is moved into the recess 227 by an adjustment screw 232. When the adjusting screw 232 rotates upward, the control board 22 will move upward with the groove 227, and at the same time move the positioning hole 236 upward, and drive the positioning pin 238 to move along the positioning hole 236 toward the center ~ axis 229 of the main bracket 226a. Furthermore, the adjustable lamp frames 222 and 224 are rotated by an angle of 0 1 toward the central axis 229 of the main support 22. Next, as shown in FIG. 5B, when the adjusting screw 232 continues to rotate upward, the control board 226b will continue to move upward along the groove 227, and the positioning hole 236 will continue to move upward. At this time, the positioning pin will move further toward the central axis 229 of the main bracket 226a, and the angle of rotation of the adjustable lamp holders 222, 224 toward the central axis 229 of the main bracket 226a will increase. It is worth noting that, in this embodiment, the maximum angle that the adjustable lamp frames 222 and 224 can rotate toward the central axis 229 of the main bracket 226a is, for example, 30 degrees. In this case, the amount of light in the partially overlapping areas 82 of the light beams 212a and 212b on the scanned object 80 will be the largest. Please refer to FIG. 3B and FIG. 5B at the same time. The following will describe the change in the amount of light in the portion 82 of the light beam 212a, 212b on the scanning object 80 before and after the adjustable light source module 200 is activated. Please refer to the figure first. Before the adjustable light source module 200 is not activated, the distance between the light beams 212a and 212b emitted by the dual light sources 2i0a and 2iOB to the partially overlapping area 82 on the scanning object go is, for example, dl. . Next, please refer to FIG. 5B. After the adjustable light source module 200 is activated, the light beams 212a, 212b emitted by the double light sources 21〇a, 210b are transmitted to the partially overlapping area 82 on the scanning object 80 at a distance of 13 1242361 14274twf. doc / 0〇6 is shortened to d2, for example. As mentioned above, the amount of incident light in a unit area of non-parallel light is inversely proportional to the square of the distance from the light source to this unit area. Before and after the adjustable light source module 200 is actuated, the distance of the partially overlapping area 82 transmitted by the light beams 212a, 212b from the dual light sources 210a, 210b to the scanned object 80 is shortened from ⑴ to d2, so it is projected on the same unit area. The amount of light in the partially overlapping area 82 on the scanned object will increase. In the same unit area, the amount of light reflected from the partially overlapping area 82 through the slot 228 (shown in FIG. 3A) and incident on the photosensitive element (not shown) also increases. Therefore, it is known that when a scanner (tree display) is used for high-speed scanning, the disadvantage that the image quality is often poor due to insufficient light from the human sensor can be improved. It is worth noting that, in a preferred embodiment of the present invention, although the first lamp holder and the second lamp holder are both adjustable lamps, it is only an example, but it is not used to limit the adjustable lamp. All light stands must be adjustable light stands. In other words, the adjustable lamp holder in this embodiment may be only one of the first lamp holder or the second lamp holder. As shown in the present invention, the adjustable light source module adopts an incident light amount adjustment mechanism, and controls the movement of the control board in the human light amount adjustment mechanism by adjusting screws. The first lamp holder and / or the second lamp holder rotate by an angle to increase the amount of light in the partially overlapping area of the two beams on the obscuring object, so that the part of the light beam reflected from the partially overlapping area and incident on the photosensitive element can provide the photosensitive element with More light = The tunable light source module invented can improve the shortcomings of the scanning light machine when the light quantity of the n mechanical light element is insufficient when the object is high, and the image quality is 1242361 14274twf.doc / 006.
