Background technique

Generally, when a scanner is used to capture an image, the clarity of the image is very important. To obtain excellent scanning quality, pay attention to the following items when scanning, such as: use good equipment and environment, correct settings and color calibration, use scanning software and image processing software correctly, and select a suitable image file format to store images documents, and selecting originals with better image quality, etc. In addition to the above conditions, the flatness of the document is also an important factor affecting the quality of the scanning result, because in some cases, even the original with the clearest image quality may be curled or creased during scanning. It is always necessary to use external force to flatten the document to reduce the distortion or shadow of the scanned output image.

Please refer to FIG. 1 , which shows a schematic diagram of using a traditional scanner. Generally, a traditional flatbed scanner includes a flip cover 12 and a scanner body 14 . In a traditional scanner, the flip cover 12 is combined with the scanner body 14 in a way that the tenon is directly engaged with the rotating shaft 16 . When only scanning a piece of A4-sized paper, the flip cover 12 can press the paper flatly on the glass platform 18; however, as shown in FIG. 1, when the thickness of the scanned document 10 increases, the traditional flatbed scanner When the cover 12 is lifted, the scanned document 10 cannot be firmly placed on the glass platform 18 , and the photosensitivity is often poor or the scanned document 10 is placed improperly, which greatly reduces the scanning quality. Therefore, when the user performs scanning work, he often needs to lightly press the flip cover 12 to increase the pressure, so that the scanned document 10 is closer to the glass platform 18. However, due to the uneven contact points between the flip cover 12 and the scanned document 10, improper force is applied And cannot solve the problem derived from the unevenness of the scanned document 10 .

In addition, whenever the flip cover 10 needs to be replaced, for example, when the scanner product model is different or the function of the product is updated, the connection between the scanner body 14 and the flip cover 12 is often slightly different, such as the position of the rotating shaft 16 or the diameter of the rotating shaft 16 The different designs of sizes make the original flip cover 12 unsuitable and unable to be smoothly assembled into another type of scanner body 14 . Therefore, the original flip cover 12 mold does not have the value of reuse, and the manufacturer must re-open the mold for the flip cover 12 according to the various connection methods between the scanner body 14 and the flip cover 12, which increases the manufacturing cost of the scanner a lot. .
