To provide a sheet carrier device that an inclination of sheet relative to a vertical direction to a transportation direction is easy to amend compared to a state where a carrier role nips when an inclination role amends the inclination.SOLUTION: A sheet carrier device comprises amendment means consisting of a first inclination amendment for amending an inclination of sheet transported relative to a transportation direction and a second inclination amendment for amending the inclination of sheet of which inclination was amended at the first inclination amendment relative to the transportation direction with higher accuracy than that of the first inclination amendment, wherein the amendment means has an inclination roll of which shaft inclines from a vertical direction to a transportation direction corresponding to the inclination of the sheet relative to a vertical direction of the transportation direction of the sheet and a carrier roll arranged in upstream of the inclination roll for shifting to a state where a nip is released when the inclination role amends the inclination at the first inclination amendment.SELECTED DRAWING: Figure 2 【課題】傾斜ロールが傾きを戻す際に搬送ロールがニップした状態を維持する場合に比べ、搬送方向に垂直な方向に対する用紙の傾きが補正しやすい用紙搬送装置を提供する。【解決手段】用紙搬送装置は、搬送される用紙の搬送方向に対する傾きを補正する第１の傾き補正と、第１の傾き補正で傾き補正された用紙の搬送方向に対する傾きを、第１の傾き補正より精度よく補正する第２の傾き補正とからなる補正手段と、を備え、補正手段は、用紙の搬送方向に垂直な方向に対する傾きに対応して、軸が搬送方向に垂直な方向から傾く傾斜ロールを有し、第１の傾き補正で傾斜ロールが傾きを戻す際にニップを解除した状態に移行する、傾斜ロールの上流に配置された搬送ロールを有する。【選択図】図２
