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 1):
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; and 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, the pair of sheet holding rollers performing a primary correction in which (1) the leading end of the sheet contacts the gate; (2) the first detector detects the position of the sheet and obtains a lateral displacement amount of the sheet; and (3) the pair of sheet holding rollers moves, while holding the sheet, in a width direction based on a detection result of the first detector, and the pair of sheet holding rollers performing a secondary correction, after the primary correction, in which (1) the first detector and the second detector detect a subsequent position of the sheet and obtain a subsequent lateral displacement amount of the sheet and an angular displacement amount while the pair of sheet holding rollers is holding the sheet; and (2) the pair of sheet holding rollers moves in at least one of the width direction and a rotation direction based on a detection result of the first detector and the second detector.
