Abstract
An automatic document feeding device (ADF) suited for being configured in a body of an apparatus is provided. The apparatus has a first and second power sources to drive the ADF to transmit a paper in or out of the body. The ADF includes a limiting structure with a limiting space, a swinging member and a blocking member. The first and second power sources drive the limiting structure and the swinging member to swing respectively. The blocking member has a first end connected to the swinging member and a second end extending toward the limiting structure. When the limiting structure is at a second position and the swinging member swings toward a third position, the second end is trapped into the limiting space. When the limiting structure moves toward a first position and the swinging member swings toward the third position, the second end escapes from the limiting space.
