Description

571568 V. Description of the invention (1) The present invention relates to an optical scanning module positioning device, and more particularly, to an optical scanning module positioning device that does not require the use of an optical scanning module positioning sheet. With the dramatic advancement of computer performance and the southern development of the Internet and multimedia technology, 'in addition to using digital cameras (D fgi7a 1 camera, DC) to directly capture image patterns' other image input of documents or pictures All operations need to use an optical scanner (0ptical Scanner) to capture analog images of text or patterns and convert them to digital signal output, which helps users to display image files on a computer or other electronic products. , Identify (OCR), edit, save and export. According to the document input method, the optical scanner can be divided into palm, scanner, sheet feeci scanner, drum scanner and flatbed scanner. Flatbed Scanner) and so on. It is worth noting that because the flatbed scanner has a relatively stable image scanning quality, and has the function of scanning reflective drafts or transmission (negative films, slides, etc.), it can be equipped with an Automatic Document Feeder (Automatic Document Feeder, ADF), one of the optical scanners used to scan a stack of documents of the same size, making flatbed scanning. In terms of the external structure, the platform scanner is mainly a casing. This casing is usually composed of a lower casing and a one located on the casing. Among them, the upper and lower windows' and the document to be scanned can be placed in this scan ^ for scanning. As for the platform scanner inside the case

Similarly, Lin is mainly similar to the above-mentioned invention. Scanner / Directly replace the above bumps with a matte surface. Scanning has i ::;: ;;? Scanners have green shooting characteristics on the upper case, and the second has a matte surface. The matte surface can be used. And because it has a matte surface; convex: the point is positioned on the body, so the material of the optical scanning module calibration calibration plate can be omitted

I 00, 2000 ·· Top cover II 0 · Correction sheet 210, 220: square object 230: scanning window 24o: matte surface A: starting point B, C: direction The preferred embodiment The present invention proposes a scanner, which has It is divided into an upper casing and a lower casing), and the casing is provided with a learning device, a driving device, a guiding device, and a control circuit. Among them, in order to save the material of the scanning module positioning device in the scanner. Cheng Dong's counter-installation work time 'like the invention considers to arrange an alternative on the upper case that can scatter the first line', for example, the surface has a matte surface The bump or a matte surface replaces the conventional optical scanning module positioning correction sheet. Please refer to Fig. 2, which shows an inner view of the upper casing of the scanner according to the present invention. In Figure 2, ^, the upper case 1 on k jl has a scanning window 2 3 0, and next to the scanning window 2 3 0, corresponding to the light wind * ', (not shown) at an appropriate position of the starting point of the scanning path, θ The pre-scan group has bumps 210 to

… 60twf.ptd Page 7 571568 V. Description of the invention (5) and bump 2 2 0. The surfaces of the bumps 2 10 and 2 2 0 are a matte surface. Taking the bump 2 1 0 as an example, the bump surface has, for example, a matte surface 2 400 that is sandblasted or bite-treated, and the optical scanning module uses a bump 21 and a bump 220 having a matte surface 24. To locate the start of its scan path. The reason is that, when the light hits the matte surface 240, the matte surface 240 will evenly scatter the light. Therefore, the same light is reflected through the matte surface 240. Compared with the general plane reflection, the matte surface 240 reflects at the same receiving point. The light intensity of light is much weaker than that of general plane reflection light. Therefore, when the optical scanning module scans the bumps 210 and 220 from other positions, the light intensity of the light received by the optical scanning module at the bumps 21 and 220 is different from that of the light received at the other positions. The light intensity is not the same. In other words, when the optical scanning module scans the bumps 21 () and the bumps 220, the light intensity of the light received by the optical scanning module is weak, and a weak induced voltage is generated. Those skilled in this art will know that each time the optical scanning module scans the document, it will start from the starting point A, and scan in the direction B (not shown), and finally reach the end point (not shown), and then from the end point Pull straight back towards starting point A. Among them, at the beginning, the position of the optical scanning module and L stay at the starting point eight, so the optical scanning module must correct the starting point A to ensure that the starting point A of each scan is correct. Position 々1 Ϊ: f ί ί The scanning module is near the starting point A, and the starting point A is determined & 22, PΛ uses the optical scanning module to scan to the bump 210 and the bump ′ 220 η to produce a weak induced voltage characteristic , 纟 locate the starting point α. In addition, it is worth noting the number of bumps or matte surfaces.
