Abstract
A scanning device includes a guide screw rod with a motor and a gear device as parts of the scanning module. The guide screw rod is fixed in the scanner along a front-to-back direction. The motor drives the gear device, which engages with the guide screw rod, causing the scanning module to move back and forth to scan a document.
