An automatic document feeder includes an upper cover, a sheet separation member and a crank. The sheet separation member includes a separation roller, a separation pad and a first elastic element. When the upper cover is opened, the upper cover is separated from the crank, and a first extension part of the crank is uplifted to push a second extension part of the separation pad, so that the separation pad is separated from the separation roller. |
