Cam 64 in the first direction of rotation During the rotation of R1, the curved cam surface 655 of the cam portion 644 pushes the first side 512 of the housing 51, and the component of the curved cam surface 655 applied to the first side 512 causes the housing 51 to follow the first Direction D1 moves.

During the movement of the housing 51 in the first direction D1, the second side 513 of the housing 51 compresses the return spring 66 to deform it, and the return spring 66 accumulates a return spring force when deformed. In addition, the housing 51 simultaneously drives the scanning component 52 and the correction sheet 53 to move along the first direction D1, so that the scanning line L of the scanning module 5 can scan a plurality of lines on the calibration sheet 53 of the fixed scanning module 5'. Image data. On the other hand, the scanning line L' of the scanning module 5' can scan the image data of the plurality of lines on the correction sheet 53 of the scanning module 5 moving in the first direction D1.

Referring to Figures 1, 10 and 11, when the curved cam surface 655 of the cam portion 644 pushes the housing 51 to a second scanning position (as shown in Figure 11), the drive motor 610 stops driving the first pulley. When the rotation of the 617 is performed, the first rotating shaft 611, the paper feed roller 612, the second rotating shaft 614, and the paper discharge roller 615 are simultaneously stopped. In addition, the scanning component 52 of the two scanning modules 5, 5' stops the scanning operation, and the image sensor 521 of the two scanning components 52 transmits the scanned image data of the plurality of lines to the control module (Fig. In the display, the control module compares the image data of the plurality of lines scanned by each image sensor 521, and first filters the abnormal image data, and then averages the remaining image data to obtain a ratio. For the value. By comparing the comparison value with a reference value previously stored by the sheet-fed scanning device 200, color correction of the image of the scanned document 1 can be performed to ensure the quality of the image of the document 1 after scanning.

Referring to FIG. 3, FIG. 11, FIG. 12 and FIG. 13, after the correcting actions of the two scanning modules 5, 5' are completed, the driving motor 610 drives the first pulley 617 to rotate in the second rotation direction R2, by the first The driving unit 613 and the second transmission unit 616 are driven such that the first rotating shaft 611, the paper feed roller 612, the second rotating shaft 614 and the paper discharge roller 615 are simultaneously rotated in the second rotation direction R2. Since the inner ring 631 of the unidirectional transmission member 63 (as shown in FIG. 9) is rotated by the first rotating shaft 611 and rotated in the second rotational direction R2, the unidirectional transmission unit slides along the inner circumferential surface of the outer ring 632 (FIG. 9). Therefore, the outer ring 632 is not rotated by the inner ring 631. Therefore, the first rotating shaft 611 does not rotate through the one-way transmission member 63 during the rotation in the second rotational direction R2.

The second side 513 of the housing 51 is pushed by the return spring accumulated by the return spring 66, so that the scanning module 5 is moved by the second scanning position in the second direction D2. During the movement of the scanning module 5 in the second direction D2, the first side 512 of the housing 51 pushes the arcuate cam surface 655 of the cam portion 644 to rotate the cam 64 in the second rotational direction R2. When the cam 64 is rotated to the initial position, the first side 512 of the housing 51 abuts against the stop surface 654 of the cam portion 644 such that the scanning module 5 is restored and positioned in the first scanning position. At this time, the paper-scanning apparatus 200 (see FIG. 1) can perform the scanning operation of the document 1.

Referring to FIG. 1 and FIG. 5, in particular, although the paper-feeding scanning device 200 of the present embodiment is described by taking a double-sided scanning device as an example, the paper-feeding scanning device 200 can also be designed to be used in application. It is a single-sided scanning device. If the sheet-fed scanning device 200 is a single-sided scanning device, it is transparent. For example, the following design enables the scanning module 5 to scan the image data of the plurality of lines of the calibration sheet 53: one of the design methods is to fix one calibration sheet 53 in the casing 2, and one scanning module 5 Then, it is movably disposed in the casing 2, and the actuation mechanism 6 drives the scanning module 5 to move the image data of the plurality of lines of the calibration sheet 53 to be scanned. In another embodiment, the scanning module 5 ′ is fixedly disposed in the casing 2 , and a casing 51 is movably disposed in the casing 2 and drives the correction plate 53 to move. The actuation mechanism 6 drives the casing. The movement of 51 causes the scanning module 5' to scan the image data of the plurality of lines of the correction sheet 53.

In summary, the paper feeding type scanning device 200 of the present embodiment drives the scanning module 5 to move relative to the scanning module 5' by the actuating mechanism 6, so that the scanning modules 5, 5' The scanning component 52 can scan the image data of the plurality of lines on the corresponding calibration sheet 53, thereby improving the accuracy of the correction. In addition, by designing the unidirectional transmission component 63 and the cam 64 of the thrusting assembly 630 on the first rotating shaft 611, the structural design is simple, and the assembly convenience can be improved. Moreover, the single drive of the drive motor 610 can simultaneously drive the paper feed roller 612 and the cam 64 of the pusher assembly 630 to rotate, without additionally adding a drive device for separately rotating the cam 64 of the pusher assembly 630. It can reduce the cost of manufacturing, so it can achieve the purpose of this new type.

However, the above description is only for the embodiments of the present invention, and the scope of the present invention cannot be limited thereto, that is, the simple equivalent changes and modifications made by the present patent application scope and the contents of the patent specification are still It is within the scope of this new patent.
