Abstract
An image pick-up module transmission arrangement includes a top cover holding a transparent glass above a scanning path defined therein and two racks along two opposite sides of the scanning path, two guide rails bilaterally fixedly fastened to the top cover at a bottom side of the scanning path, an image pick-up module reciprocated in the scanning path along the guide rails, the image pick-up module having pulleys revolvably supported on the guide rails and spring leaves disposed in contact with the guide rails, and a transmission shaft mounted in the image pick-up module, the transmission shaft having two gear wheels at two opposite ends meshed with the racks, the gear wheels being rotated clockwise/counter-clockwise by a power drive in the image pick-up module, causing the image pick-up module to be reciprocated in the scanning path along the guide rails.
