Abstract
A scanning device and a scanning method thereof are provided. The scanning device includes a scanning group, a paper-feed roller and a calibration portion. The scanning group includes a line light source generating module and a scanning module. The line light source generating module includes a point light source, a light-guiding plate and a casing. The light emitted by the point light source along a first direction is converted into a line light source through a light-guiding plate disposed in the casing. The light emitted by the line light source along a second direction is emitted from an opening of the casing. The scanning module, along the first direction, includes a scan document region and a calibration region. The light reflected through the to-be-scanned document is received in the scan document region. The calibration portion disposed on the casing or the paper-feed roller corresponds to the calibration region.
