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, which may be incorporated in an image forming apparatus, includes an image reader, a color reference body, a biasing body, a reading gap forming device, and a driving device. The image reader reads an image of an original document. The color reference body has a white reference face to position facing the image reader within a predetermined range in a document width direction. The biasing body biases the color reference body to the image reader. The reading gap forming device forms a reading gap while receiving a biasing force from the biasing body on the outside of the predetermined range. The driving device has a force drive transmission body engaged with a center of the color reference body in the document width direction and drives the color reference body in the document width direction at the center via the force drive transmission body.
