摘要： A feeding device includes a paper feed tray, a detector on an image forming apparatus main body, a control member rotatably supported by the paper feed tray, and spacers. The detector includes movable pieces and contact points corresponding to the movable piece, and switches each contact point by the position of the corresponding movable piece. The control member includes a control surface formed on its outer circumferential surface with projecting and recessed portions. The projecting and recessed portions are disposed in a pattern corresponding to rotation angles in an area of the control surface facing the movable pieces. Controlling the positions of the movable pieces according to the pattern encodes paper size. Each movable piece is lined in the circumferential direction facing the control surface. The outer circumferential surface of the projecting portions is formed in a cylindrical surface shape centering around the rotational axis of the control member.

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.

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 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.
