Abstract:
A sheet conveying device, which is included in an image forming apparatus, includes a detector to detect a lateral end face of a sheet, a first pair of rollers to hold and convey the sheet and swing in a direction parallel to a plane of the sheet, a second pair of rollers to convey the sheet together with the first pair of rollers, and a controller to rotate the first pair of rollers to multiple angles, detect time changes at each angle at the lateral end face while conveying the sheet, and determine a home position corresponding to a position where respective rates of the time changes of the sheet at the first and second nip regions are substantially identical to each other or a home position having a least difference of rates of the time changes of the sheet at the first and second nip regions.

Claim (Index 10):
A sheet conveying device comprising:\n a detector configured to detect a position of a lateral end face of a sheet conveyed in a sheet conveyance passage; a first drive device; a second drive device; a first pair of rollers forming a first nip region, the first pair of rollers configured to convey the sheet in response to driving power from the first drive device; a second pair of rollers forming a second nip region and disposed either one of an upstream side and a downstream side of the sheet conveyance passage in a sheet conveying direction from the first pair of rollers; and a controller configured to perform a home position adjustment operation by,\n causing the second drive device to rotate the first pair of rollers to multiple angles in a direction parallel to a plane of the sheet, \n causing the detector to detect time change at each of the multiple angles at the lateral end face of the sheet while conveying the sheet by the first pair of rollers and the second pair of rollers, \n determining a position having a least difference between a rate of the time change after the sheet has reached the first nip region of the first pair of rollers and a rate of the time change after the sheet has reached the second nip region of the second pair of rollers, and \n setting the position as a home position of the sheet conveying device, such that, during a position correction operation subsequent to the home position adjustment operation, the first pair of rollers returns to the home position after rotating and gripping the sheet to perform the position correction operation.
