Abstract:
1. A sheet conveying apparatus having: a first conveying unit for conveying a sheet; a second conveying unit which is disposed downstream in the conveying direction of the sheet conveyed by the first conveying unit to convey the sheet, wherein the apparatus conveying the sheet and performing skew correction for correcting the orientation of the sheet with the front edge in the conveying direction of the sheet abutting against the second conveying unit so as to make the front edge of the sheet perpendicular to the conveying direction, wherein the first conveying unit includes a conveying roller member for conveying the sheet, a conveying shaft for supporting the conveying roller member such that the conveying roller member is movable in the axial direction of the conveying shaft and the rotational direction relative to the shaft, a roller driving unit for rotationally driving the conveying shaft, and a limiting unit for limiting the axial movement of the conveying roller member and the rotational movement of the roller member, and wherein the limiting unit limits the axial movement of the roller member to a first range in a state where the shaft rotates in the conveying direction to rotate the roller member, and limits the axial movement of the roller member to a second range larger than the first range in a state where the shaft is rotated by the roller that is rotated by the sheet conveyed by the second conveying roller.
