摘要： An optical reading device of a scanning apparatus includes two light sources and a movable lens. The first light source emits a first light when the optical reading device is operated in a flatbed scanning mode. The second light source emits a second light when the optical reading device is operated in a sheetfed scanning mode. The movable mirror is selected to allow for passing the first light without being obstructed by the movable mirror in the flatbed scanning mode or allow for reflecting the second light coming from the second mirror in the sheetfed scanning mode. Due to the special design, the overall volume of the scanning module is reduced.
