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 14):
The sheet conveying device according to  claim 11 ,\n wherein the gate is a pair of upstream side sheet conveying rollers disposed upstream from the pair of sheet holding rollers in the sheet conveying direction, wherein the first detector is disposed downstream from the pair of upstream side sheet conveying rollers in the sheet conveying direction, wherein the pair of upstream side sheet conveying rollers is configured to (1) correct the angular displacement amount of the sheet by contacting the leading end of the sheet conveyed toward the pair of upstream side sheet conveying rollers while the rotation of the pair of upstream side sheet conveying rollers is being stopped, (2) move from a reference position in the width direction corresponding to the lateral displacement amount of the sheet based on a detection result obtained by the first detector before the sheet is conveyed to the pair of sheet holding rollers by the pair of upstream side sheet conveying rollers, and (3) move the pair of sheet holding rollers while holding the sheet to the reference position, operable to correct the lateral displacement amount of the sheet, and wherein, after the correction of the lateral displacement amount of the sheet, the pair of sheet holding rollers is configured to (1) move while holding the sheet from the reference position, operable to correct at least one of the subsequent lateral displacement amount of the sheet and the subsequent angular displacement amount of the sheet, with a feedback control, based on the at least one of a detection result of the subsequent lateral displacement amount of the sheet and a detection result of the subsequent angular displacement amount of the sheet, continuously obtained by the first detector and the second detector, while the pair of sheet holding rollers is holding and conveying the sheet.
