Abstract

An image scanning device and a positioning method thereof are provided. The image scanning device includes a scanning module, a processor and a calibration sheet. The processor is coupled to the scanning module. The calibration sheet is configured on a non-scanning region of the image scanning device. The calibration sheet includes at least one mark, and each mark has a first level-block and a second level-block, wherein the first level-block and the second level-block are configured in sequence by a first moving direction that the scanning module moves from the non-scanning region to a scanning region. The processor controls the scanning module to scan, and computes the position of a reference point based on the level difference retrieved by the scanning module. Therefore, the image scanning device can move the scanning module to a scan-position according to the reference point.
