A multi-purpose scan device using the same power source includes a flatbed scanner, an ADF, a motor, and a power-switching mechanism. The flatbed scanner has a scanning module and a power transmission mechanism for moving the scanning module back and forth in the flatbed scanner. The ADF has a sheet-feeding mechanism for feeding a document across the scanning module, which scans the document. The power-switching mechanism selectively transmits power of the motor to the sheet-feeding mechanism and the power transmission mechanism.
