摘要： An image reading device, which can be included in an image forming apparatus, includes an image pickup device, a transparent member, a traveling body, and a housing. The traveling body includes a light source to emit light and guides the light reflected from a surface of the document to the image pickup device while moving in a sub scanning direction along the document surface on the transparent member. The housing accommodates the image pickup device and the traveling body, and includes a base member including a rectangular bottom surface and a side surface, and a rail member including a rail surface and a first vertical surface. The rail member further includes a fixing part that is a surface to be fixed to the bottom surface of the base member and to extend from one end of the rail member in the sub scanning direction to the other end.

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： 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 sheet conveyance device includes a sheet mount on which a standard-sized sheet is mountable; a first conveyor to bring in the sheet from the mount, convey the sheet through a reverse conveyance path such that the sheet passes through a specific operation position, and eject the sheet into a sheet ejection area outside the mount; and a second conveyor to bring in a hard sheet with a higher bending rigidity than the sheet from one end of a straight conveyance path along a plane passing through the specific position of the reverse path, and eject the hard sheet conveyed along the straight path from another end of the straight path at a sheet ejection area side. The mount includes a hard sheet ejection port to let through at least a leading edge portion of the hard sheet to be ejected from the second conveyor in a sheet ejection direction.
