動原稿搬送装置。 A double-feed prevention paper feeding means consisting of a plurality of upper paper feed rollers each having a cutout part formed on a part of the circumferential surface and a lower return roller located between the rollers is connected to the cutout part and the lower return roller when paper feeding is stopped. The document is arranged so that a paper passage path is formed between the roller and the paper feeding means, and the document is conveyed to a predetermined position on the contact glass on the downstream side of the double-feed prevention sheet feeding means, and the document is transferred after scanning the document image. A paper feed/discharge roller is provided for returning and conveying the paper, and by bending and deforming the lower free end toward the downstream side in the paper feeding direction, only the paper is allowed to pass toward the paper supply/discharge roller side, and the paper is transported by the paper feed/discharge roller. A flexible path switching member that guides the original to be returned and conveyed above the paper feed/discharge roller is moved diagonally across the paper feed path from the double feed prevention paper feed means to the paper feed/discharge roller. The automatic document feeder is provided with a flexible guide member that guides the leading edge of the document fed by the double-feed prevention paper feeding means toward the lower free end side of the path switching member. An automatic document feeder characterized by:
