The present invention provides a self-propelled image read module, which comprises a sensor, a guide rod, a motor, a gear set, and a belt. The guide rod is fixed on a base of a scanner. The sensor is slidably matched on the guide rod. The motor is disposed at one side of the sensor. The gear set is connected to the motor. The belt is fixed on the base. The belt passes through between and contacts a transmission wheel and an idle wheel of the gear set. Thereby, a scanner's image read module of simple assembly, low cost, and small size is formed.
