Patent ID: 8684353

Claim:
A sheet conveying apparatus comprising a skew feeding correction portion arranged to correct a skew feeding of a sheet conveyed along a sheet conveying path in a sheet conveying direction, the skew feeding correction portion including: a reference member extending in the sheet conveying direction; a first pair of skew-feed rollers; second pair of skew-feed rollers positioned downstream of the first pair of skew-feed rollers in the sheet conveying direction; a third pair of skew-feed rollers positioned downstream of the second pair of skew-feed rollers in the sheet conveying direction; wherein the first, second and third pairs of skew-feed rollers are each arranged to nip the sheet and to convey the sheet towards the reference member such that the sheet abuts the reference member to correct a skew of the sheet; a moving mechanism arranged to move the first pair of skew-feed rollers between a nip position in which the first pair of skew-feed rollers are in contact with each other and a separate position in which the first pair of skew-feed rollers are separated from each other; a controlling portion arranged to control the moving mechanism so as to move the first pair of skew-feed rollers from the nip position to the separate position after the sheet, conveyed by the first pair of skew-feed rollers, is nipped by the second pair of skew-feed rollers and before the sheet is nipped by the third pair of skew-feed rollers, wherein a nip pressure of the second pair of skew-feed rollers is set so that the sheet is slipped in a nip portion of the second pair of skew-feed rollers to release a deflection of the sheet caused between the reference member and the second pair of skew-feed rollers after the first pair of skew-feed rollers moves to the separate position.
