Abstract:
1. A sheet conveying device for conveying a sheet, the sheet conveying device comprising: an image sensor configured to sense a position of a side end of the sheet in the width direction; a displacement-amount detecting unit configured to detect an amount of displacement of a conveyed sheet from a conveyance reference in a width direction being substantially perpendicular to a sheet conveying direction in response to a signal from the image sensor; and a pair of sheet conveying rollers configured to be shiftable in a direction substantially perpendicular to the sheet conveying direction while pinching the sheet having the amount of displacement detected by the displacement-amount detecting unit, wherein, before the sheet reaches the sheet conveying rollers, the sheet conveying rollers are shifted based on the amount of displacement detected by the displacement-amount detecting unit from a conveyance-reference position in a direction in which the sheet is displaced and, after the sheet reaches the sheet conveying rollers, the sheet conveying rollers are shifted while pinching the sheet so as to reduce the amount of displacement.
