Abstract:
A sheet conveying apparatus which corrects skew feed of a sheet by pressing the sheet conveyed by conveying means against a stationary registration roller pair to form a loop in the sheet and then rotates said registration roller pair to convey the sheet, said apparatus comprising:a loop formation space, which is disposed downstream of said conveying means and upstream of said registration roller pair, in which the sheet forms the loop; an upper member for defining an upper surface of said loop formation space, said upper member extending in a direction of said registration roller pair, which abuts against the sheet when the sheet forms the loop; a lower member, which is biased upward, for defining a lower surface of the loop formation space; an engaging member for engaging said lower member, which is biased upward; and an elastic member for biasing said lower member upward, wherein said lower member directs the sheet conveyed by said conveying means toward said registration roller pair and along said upper member, is moved downward when abutted against a surface of the sheet that forms an inside of the loop, and is pressed by the sheet conveyed by said registration roller pair while said registration roller pair attenuates the loop in the sheet.
