摘要： A rotation drive device includes a driven rotation member, a driving rotation member, a rotation relay member, a shaft, and a holder. The rotation relay member transmits only a unidirectional rotational driving force from the driving rotation member to the driven rotation member. The rotation relay member includes a housing and a cylindrical one-way clutch. A contact portion between the driving rotation member and the shaft is configured to rotate the driving rotation member and the shaft to transmit the driving force to an inner peripheral side of the cylindrical one-way clutch via the shaft. The driving rotation member includes a boss projected toward the holder and rotatably held in the holder. A portion of the shaft to support the driving rotation member and an inner wall surface of a through hole of the driving rotation member are shaped to rotate the shaft and the driving rotation member. together.

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.

摘要： A document feeder, which may be incorporated in an image forming apparatus, includes a sheet conveying guide, at least one recess, a frame, and at least one protrusion. The sheet conveying guide is disposed facing an exposure glass on an apparatus body and guides an original document passing over the exposure glass when the document feeder is closed to the apparatus body. The recess is disposed on the apparatus body at both ends of the exposure glass in a lateral direction orthogonal to a document conveying direction. The frame is openably closable about one end side of the apparatus body in the lateral direction and vertically movably holds the sheet conveying guide. The protrusion is disposed on the frame facing the recess. The sheet conveying guide and the frame are secured to each other while the recess and the protrusion are engaged with each other in the closed state.

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： A sheet conveying device includes a sheet container, a separation feeder, a plurality of conveyance drivers, a multifeed detector, a sheet detector, and a conveyance controller. The conveyance drivers are driven to convey a sheet to a conveyance completion position on a sheet conveyance path. The multifeed detector detects occurrence of a multifeed on the conveyance path. The sheet detector detects presence or absence of the sheet at a sheet detection point on the conveyance path. The conveyance controller controls the conveyance drivers to be continuously driven until a preceding sheet preceding multifed sheets is conveyed to the conveyance completion position after the multifeed detector detects the occurrence of the multifeed. The conveyance controller controls the conveyance drivers to stop in a period in which at least one of the multifed sheets is present at the sheet detection point after the preceding sheet is conveyed to the conveyance completion position.

摘要： A medium conveying device includes a conveying lower face and a placing table. The conveying lower face has an introduction end and an ejection end. The conveying lower face inclines upward and extends linearly from the introduction end to the ejection end. The placing table is provided pivotally on an introduction end side and displaced between a first position and a second position to place a sheet-like conveyance target medium to be introduced from the introduction end. The placing table forms a linear conveying route when occupying the first position and forms a bent conveying route when occupying the second position.
