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 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： 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 image reading device includes a plurality of conveyance rollers to convey a sheet, a motor to drive the plurality of conveyance rollers, an image reading unit to read an image of the sheet, a control device to perform a stop control that stops the sheet in a course of a conveyance path, and a clutch to transmit a driving force of the motor. A first conveyance roller group includes at least one of the plurality of conveyance rollers upstream from a leading end of the sheet stopped by the stop control in a conveyance direction, to which the driving force is transmitted via the clutch. A second conveyance roller group includes at least one of the plurality of conveyance rollers downstream from the leading end of the sheet stopped by the stop control in the conveyance direction, to which the driving force is transmitted without the clutch.
