A drive mechanism of scanner, includes a delivery device, a first rotational speed motor and a second rotational speed motor. The said delivery device consists of a actuating wheel, a passive wheel and a circular conveyor belt wherein the circular conveyor belt is harnessed on actuating wheel and passive wheel respectively, the axes of the above-mentioned two passive wheels are attached to two ends of inner side diameter of actuating wheel, the output shaft of the first rotational speed motor is provided with a actuating skew gear and is engage with two passive skew gears respectively. The output shaft of the second rotational speed motor is provided with an actuating skew gear and is engage with two passive skew gears respectively. The drive mechanism drive two passive skew gears by means of the above-mentioned two motors so enable drive mechanism of the scanner to create specific rotational speed and scan document image.
