    摘要: 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 conveyance unit conveys a document to an image reading position. The image reading unit reads an image of the document. The color reference member faces the image reading unit and includes a white reference face to correct shading. The moving assembly relatively moves the image reading unit and the color reference member. The movement regulator regulates a relative movement of the image reading unit and the color reference member by the moving assembly. The drive source includes a common 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 by the conveyance unit. 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 revere rotation angle. The moving assembly relatively moves the image reading unit and the color reference member in a second reverse rotation drive region where the rotation output shaft is rotated in the reverse rotation direction beyond the set reverse rotation angle.

    摘要: An image reading device includes an image reader movable along an image reading face, a casing to house the image reader, including a restraint holder, and a restraint to be held by the restraint holder of the casing and configured to restrict movement of the image reader. The restraint includes an operation portion to be disposed outside the casing. The operation portion is operated to move the restraint, in the restraint holder, to: a restricting position to restrict movement of the image reader; a first unlock position to cancel restriction of movement of the image reader; and a second unlock position at which movement of the image reader is not restricted. At the first unlock position, movement of the restraint to the restricting position is allowed. From the second unlock position, movement to the restricting position is less smooth than movement from the first unlock position to the restricting position.
