Abstract:
A sheet conveying device, which is included in an image forming apparatus, includes a drive device, a pair of sheet holding rollers to convey a sheet in a sheet conveying direction, a gate to which a leading end of the sheet contacts, a first detector disposed upstream from the pair of sheet holding rollers to detect a position of the sheet and a second detector disposed downstream from the pair of sheet holding rollers to detect a position of the sheet. The pair of sheet holding rollers performs a primary correction to detect and correct a lateral displacement amount of the sheet by moving the pair of sheet holding rollers while holding the sheet, and then performs a secondary correction to detect and correct at least one of a subsequent lateral displacement of the sheet and an angular displacement of the sheet.

Claim (Index 11):
A sheet conveying device comprising:\n a drive device; a pair of sheet holding rollers rotated by the drive device, the pair of sheet holding rollers configured to convey a sheet, while holding the sheet, in a sheet conveying direction; a gate to which a leading end of the sheet being conveyed in a sheet conveyance passage contacts; a first detector disposed upstream from the pair of sheet holding rollers in the sheet conveying direction, the first detector configured to detect a position of the sheet conveyed in the sheet conveyance passage; a second detector disposed downstream from the pair of sheet holding rollers in the sheet conveying direction, the second detector configured to detect a position of the sheet conveyed in the sheet conveyance passage; and a controller configured to control a movement of the pair of sheet holding rollers based on at least one of a detection result of the first detector and a detection result of the second detector, the controller, after the leading end of the sheet contacts the gate and the sheet is held by the pair of sheet holding members, causing: (1) the pair of sheet holding rollers to move in a width direction of the sheet based on the detection result of the first detector; and (2) the pair of sheet holding rollers to move at least one of the width direction of the sheet and a rotation direction of the sheet based on the detection result of the first detector and the detection result of the second detector while the sheet is being conveyed by the pair of sheet holding rollers.
