Abstract
An automatic document feeder includes a horizontal feeding path, a curve feeding path, a scanning unit arranged in the horizontal feeding path, a motor, a movable document guider, an actuator, a feeding roller arranged in the horizontal feeding path, and a transmission structure. One end of the curve feeding path is connected with a common document inlet, the other end of the curve feeding path is connected with a middle of the horizontal feeding path. A gentle bending corner is formed at a junction area between the curve feeding path and the horizontal feeding path. The motor outputs a forward torque or a converse torque. The movable document guider is rotatably positioned near the gentle bending corner. The actuator is rotatably positioned near the gentle bending corner. The transmission structure is connected among the motor, the feeding roller and the actuator.
