A document feeder (3) includes a feed tray (10), a catch tray (20), a carrying path (31) extending from the feed tray to the catch tray via a scanning position (R), a reversal path (32) diverging from a point on the carrying path downstream relative to the scanning position and connecting to a point on the carrying path upstream relative to the scanning position, a switchback mechanism (53) conveying a sheet back to front from the reversal path toward the scanning point, an ejection mode switching mechanism having a flap (61) provided upstream relative to the catch tray movably relative to an ejection roller (49), the ejection mode switching mechanism switching an ejection mode by moving the flap between a first mode to eject the sheets on already-ejected sheets (M1) and a second mode to insert the sheets under already-ejected sheets. The flap forms part of the reversal path in the first mode. |
