Patent ID: 8523175

Claim:
A sheet transport apparatus comprising: a sheet transport portion that transports a sheet in a first transport direction and a second transport direction that is opposite to the first transport direction; a bending member that bends without breaking the sheet by corrugating the sheet in an orthogonal direction that is orthogonal to the transport direction of the sheet and conforms to a surface of the sheet; and a restriction member that restricts, in a perpendicular direction that is orthogonal to both the first transport direction and the second transport direction, and the orthogonal direction, a corrugation in the sheet bent by the bending member, wherein the restriction member is provided on an upstream side in the first transport direction of the bending member, wherein the restriction member is provided on the upstream side in the first transport direction of a tip in the perpendicular direction of the bending member, and wherein the sheet transport portion comprises a pair of transport rollers for transporting the sheet, and is configured to transport the sheet in a horizontal direction, diagonally upward or diagonally downward, the tip of the bending member is provided on a downstream side in the first transport direction of a nip portion of the pair of transport rollers, and the bending member is configured to bend a transported sheet by corrugating the transported sheet in the orthogonal direction from above, and the restriction member is configured to restrict the corrugation from below the sheet.
