Abstract
A scanning device includes an upper cover, and a separation module detachably and changeably assembled in the upper cover. A middle of a bottom surface of the upper cover is recessed in an upward direction to form an assembling groove. The separation module includes a fastening holder, a separation roller assembly received in the fastening holder, a torsion limiter and a sealing cover. The torsion limiter is engaged with the separation holder. The sealing cover is mounted under the fastening holder. Different separation modules detachably and changeably assembled in the assembling groove are capable of being equipped with different torsion limiters. When the scanning device scans papers of which grams are different, torsion values of the scanning device are capable of being adjusted by virtue of changing the different separation modules equipped with the different torsion limiters.
