Claim:
An image processing apparatus comprising: a U-turn conveying path comprising: a first conveying path on which a sheet is conveyed; a curved conveying path having an arc shape and on which the sheet conveyed from the first conveying path is conveyed; and a second conveying path on which the sheet conveyed from the curved conveying path is conveyed; a first image reading section facing the first conveying path and configured to read an image recorded on a first surface of the sheet conveyed on the first conveying path; a second image reading section facing the second conveying path and configured to read an image recorded on a second surface of the sheet conveyed on the second conveying path; a pair of first conveying rollers positioned upstream of the first conveying path in a conveying direction and configured to nip and convey the sheet to the first conveying path; a pair of second conveying rollers positioned at a boundary between the first conveying path and the curved conveying path and configured to nip and conveyed the sheet to the curved conveying path; a pair of third conveying rollers positioned downstream of the curved conveying path in the conveying direction and configured to nip and convey the sheet to the second conveying roller; and a pair of discharge rollers positioned downstream of the second conveying path in the conveying direction and configured to discharge the sheet from the second conveying path, wherein the pair of the first conveying rollers, the pair of the second conveying rollers, the pair of the third conveying rollers and the pair of the discharge rollers are positioned such that a distance between a third nip point that each of the pair of the third conveying rollers contacts each other and a fourth nip point that each of the pair of the discharge rollers contacts each other is larger than a distance between a first nip point that each of the pair of the first conveying rollers contacts each other and a second nip point that each of the pair of the second conveying rollers contacts each other, and wherein the first nip point and the second nip point are positioned in a first area defined by an imaginary line extending upward from the third nip point and the fourth nip point respectively.
