Patent ID: 8308160

Claim:
A sheet conveying apparatus which conveys a sheet, comprising: a pair of first oblique feed rollers which obliquely convey the sheet; a pair of second oblique feed rollers which are arranged downstream in the sheet conveying direction of the pair of first oblique feed rollers and which obliquely convey the sheet; a reference surface which is arranged along the sheet conveying direction and onto which the side end of the sheet obliquely conveyed by the pair of first oblique feed rollers and the pair of second oblique feed rollers is abutted, thereby correcting skew feeding of the sheet; a pair of conveying rollers which convey the sheet to the pair of first oblique feed rollers, a sheet conveying speed of the pair of conveying rollers in the sheet conveying direction being set to be higher than a sheet conveying speed of the pair of first oblique feed rollers in the sheet conveying direction; a separation mechanism which separates the pair of conveying rollers; and a controlling portion which controls the separation mechanism so that the pair of conveying rollers is separated after a sheet conveyance by the pair of first oblique feed rollers has elapsed a predetermined time before the sheet conveyed by both of the pair of conveying rollers and the pair of first oblique feed rollers reaches the pair of second oblique feed rollers.
