JiL· 4. J! ί The image of the creation The shadow of the image is like the optical sensing stereogram of the reading module. As shown in FIG. 6B and FIG. 6C, the image reading module 2'' of the embodiment of FIG. 5A is mounted on the upper left corner of the display structure 8. The image reading module 10 of the embodiment of FIG. 4 is mounted on the lower right corner. Thus, the two optical sensors 12 can be set to produce a corner in the interior of the front frame 81 for instantly capturing the non-transparent body of the light projection. Generally, the uncr's words usually reach the target of touch by the human fingers HI, H2, and H3. Therefore, as shown in FIG. 6B and FIG. 6C, the non-transparent body of the present embodiment is a human finger HI, H2. H3 'The positions pressed by the fingers HI, H2, and H3 are the purpose of the touch points P1, P2, and P3, respectively. The purpose of detecting the human fingers H1, Η2, Η3 is by optical sensing. The position, in turn, the displacement change and the speed change of the touch points ρι, ρ2, ρ3, and is used to control the software or hardware of the operating electronic device (such as a computer). Therefore, the principle of the sensing is: using the optical sensor 12 to immediately capture the light projection page 9 / total 23 page form number Α 0101 M409651 face; because the human fingers HI, H2, H3 are opaque, Therefore, the occlusion effect of the light blocking can be generated, so that the optical sensor 12 can detect the instantaneous coordinates of the touch points PI, P2, and P3, and the touch point PI can be further obtained through a simple calculus operation. , P2, P3 movement speed and acceleration. Further, since the light rays 92 emitted from the plurality of light guiding strips 11 are perpendicular to each other, any position of the finger HI, H2, H3 moved to the display structure 8 can be detected. [0019] Generally speaking, more touch points are generally more likely to cause inaccurate detection and misjudgment of coordinates. As shown in FIG. 6B and FIG. 6C, since the touch point P1 of the finger H1 and the touch point P2 of the finger H2 have the same abscissa, if only the optical i of the upper side is used, 1% is misjudged. , or the touch points PI, Ρ21 can not be clear, so the actual .· . > . *·»·« 〆* ^ ' The example is to compensate for the error through the second or even the third light guide 11 Eliminate the chance of misjudgment or unrecognizable, improve accuracy, and make the coordinates of the interpretation more precise. In other words, a plurality of image reading modules can be installed in a display structure 8 to cause the plurality of light guiding strips 11 to emit invisible light, and at the same time, the plurality of optical sensors 12 detect multiple touch points, thereby overcoming Multi-touch "contact point overlap" or "detect dead angle" problem, so it has higher accuracy, lower chance of misjudgment, very convenient. [0020] Thereby, the image reading module of the present invention can be applied to various commercial products or electronic devices, so that the commercial product or the electronic device does not need to be targeted for the detection range of the optical sensor. It is very convenient to apply contrast and correction of color and brightness. Therefore, the image reading module does not need to be combined with an additional image processing chip to filter the background noise, so the error is lower and the cost is cheaper.
