A compact ADF (auto-document feeder) for feeding a duplex document includes, a first feeding path starting from a document setting table to an exposing area and is formed in a U-shaped state, a second feeding path starting from the exposing area to an ejecting roller, a switch-back path disposed downstream of the second feeding path and above a document ejecting tray, and an inverting path starting from an entrance of the switch-back path to the first feeding path. A switching gate is pivotally disposed downstream of the second feeding path and above the ejecting tray to selectively lead the document either to the ejecting tray, or the switch-back path, or to the inverting path each from the second feeding path.
