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： An image forming apparatus includes an image forming unit, a first sheet stack portion, a sheet output section, and a post processing unit. The image forming unit forms an image on a sheet. The first sheet stack portion is provided at an upper face of the image forming unit. The sheet output section outputs the sheet on which the image is formed by the image forming unit from one side of the image forming apparatus to the first sheet stack portion. The post processing unit is provided adjacent to a lateral side of the image forming unit at an upstream side of the sheet output section to execute post processing on the sheet. A sheet subjected to post-processing by the post-processing unit is output to the first sheet stack portion from the same direction as a sheet not subjected to post-processing by the post-processing unit.

摘要： In an image forming apparatus, when a first sheet discharger discharges a sheet bearing an image in a first direction from a proximal end to a distal end of the image forming apparatus, a post-processing device performs post-processing including at least one of stapling, punching, stamping, and sorting of the sheet discharged from the first sheet discharger. After a second sheet discharger discharges the processed sheet in a second direction opposite to the first direction in which the first sheet discharger discharges the sheet bearing the image, a sheet stacker stacks the sheet discharged from the second sheet discharger. A sheet conveyance path is provided between the first sheet discharger and the second sheet discharger. An opening is provided between the sheet stacker and an image reader so that the sheet discharged from the second sheet discharger can be retrieved from the sheet stacker in the second direction.

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.

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.
