摘要： An image reading device, which is included in an image forming apparatus, includes a first transparent body, a second transparent body, a holding body, and a reading body. The second transparent body is disposed separated from and inclined at a predetermined angle to the first transparent body. The holding body holds the first and second transparent bodies. The reading body moves in a sub-scanning direction along the first and second transparent bodies. The holding body includes a flat face and a frame-shaped face. The flat face is contiguous to the first transparent body on a same plane and smoothly connected with the second transparent body. The frame-shaped face projects outwardly beyond the second transparent body facing the reading body. The reading body moves and contacts the first transparent body and the holding body, and moves with a gap relative to the second transparent body.

摘要： An image reading device includes: a reading unit; a first detecting unit that detects a position of the reading unit in the sub-scanning direction; a second detecting unit that detects a position of the reading unit in the sub-scanning direction; and a calculating unit that calculates a skew quantity and a skew direction of the reading unit, based on a difference, introduced by the skew, between a travel distance by which the reading unit has travelled from a measurement reference position located on an upstream side of the first detecting unit and the second detecting unit in a moving direction to a point where the reading unit is detected by the first detecting unit, and a travel distance by which the reading unit has travelled from the measurement reference position to a point where the reading unit is detected by the second detecting unit.

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 feeder, which is included in an image reading device and an image forming apparatus, includes first and second document trays, a document output tray, a document conveying passage, multiple document conveying bodies, a drive source, a detector, and a controller. The multiple document conveying bodies include a document holding and conveying body to convey and hold the original document sheet on the second document tray. On detection of the original document sheet on the second document tray while conveying a different original document sheet from the first document tray, the controller stops feeding the different original document sheet, causes the different original document sheet downstream from the document holding and conveying body in a document conveying direction to be conveyed to the document output tray, and stops the drive source after the different original document has been conveyed to the document output tray.

摘要： A sheet conveying device includes a separator to separate a sheet from sheets. The separator includes a separation conveyor; a separation resistance member to press against the separation conveyor via the sheet; a resistance-member holder; a biasing member to contact and bias the resistance-member holder to press the separation resistance member toward the separation conveyor, the resistance-member holder to rotate about a resistance-member rotary shaft to separate from the biasing member in detaching from an apparatus body; and a biasing-member holder configured to rotate about a biasing-member rotary shaft to more incline the biasing member in a state, in which the biasing member is spaced apart from the resistance-member holder, in a moving direction of the resistance-member holder to detach from the apparatus body than the biasing member in a biasing state in which the biasing member biases the resistance-member holder in contact with the resistance-member holder.

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： An automatic document feeding device includes a document tray, an ejection tray, and a document takeout port. The document tray is rotatably attached to a rotation fulcrum provided in a body of the automatic document feeder, to load a document. The document tray includes a first positioner and a second positioner. The first positioner is disposed at a front side of the body in a direction perpendicular to a document feed direction. The second positioner is disposed at a depth side of the body in the direction perpendicular to the document feed direction. The first positioner is disposed upstream from the rotation fulcrum in the document feed direction and above the document takeout port in the body. An upper portion and side surfaces of the first positioner in the direction perpendicular to the document feed direction are surrounded by the document tray in a closed state of the document tray.
