In this way, it will not only bring inconvenience to the operation, but also may affect the operation due to the loss of the positioning plate. .

The purpose of the utility model is to provide an easy-to-operate movable correction area adjustment device of an image scanning device.

The purpose of this utility model is achieved in this way: the movable correction area adjustment device of the image scanning device, which includes: a shiftable correction sheet, a guide mechanism, a rectangular window is set at the center of the top plate of the image scanning device, and bears Set a transparent manuscript carrying surface, and set a correction area on the scanning start side of the manuscript carrying surface as a correction area before formal scanning. Starting side: the guide mechanism is arranged on the top surface of the top plate of the body, and is adjacent to one side edge of the rectangular window of the top plate, and the shiftable correction sheet is guided by the guide mechanism and shifted in the first correction area, the second correction area.

The above-mentioned design is combined with the scanner body through the guide groove structure, and through the displacement of the shiftable correction sheet, it can prevent the correction area of the top light source from being violated during scanning, and at the same time avoid the loss of the positioning plate and affect the scanning operation. Reach the effect of saving scanning time and being convenient to use.

As shown in Figure 3-7: the utility model includes: a shiftable correction sheet 4, a guide mechanism 5, a rectangular window is set in the center of the top plate 31 of the image scanning device 3, and a transparent manuscript bearing surface is placed 32. A correction area is provided on the scanning start side 321 of the manuscript carrying surface 32 as a correction region before official scanning. Side 321; the guide mechanism 5 is arranged on the top surface of the top plate 31 of the body 3, and is adjacent to one side edge of the rectangular window of the top plate, and the displaceable correction sheet 4 is guided by the guide mechanism 5 and shifted in the first correction Zone 6, second calibration zone 7. The body 3 is equipped with existing components such as a travel module, a driving mechanism, an image sensing element, a guide rod, and a circuit board. There is an upper cover on the body 3, which is pivotally connected to a backlight module, and there are signs for placing manuscripts.
