Abstract
An automatic document feeding device includes a conveyance unit, an image reading unit, a color reference member, a moving assembly, and a drive source. The drive source includes a rotation output shaft to drive the conveyance unit and the moving assembly. The drive source changes the rotation output shaft from a forward rotation direction to a reverse rotation direction to reversely rotate the rotation output shaft to a set reverse rotation angle set in advance, according to a condition of conveyance of the document. In a rotation transmission route from the rotation output shaft to the moving assembly, the movement regulator is disposed in a first reverse rotation drive region from when a rotation direction of the rotation output shaft is changed to the reverse rotation direction to when a rotation angle of the rotation output shaft after the change in the reverse rotation direction reaches the set reverse rotation angle.
