A rotation shaft (20) configured to rotate in a direction (Af) in which a sheet (S) is fed in and in a direction (Ab) in which the sheet is wound while supporting the sheet, a control unit (100) configured to apply tension to the sheet by the rotation shaft by controlling torque applied to the rotation shaft, an ejection unit (51,52) configured to eject light-curable liquid onto the sheet, and an irradiation (61-63) device configured to irradiate light onto the liquid ejected onto the sheet by the ejection unit are provided. The tension applied to the sheet by the rotation shaft when the rotation shaft rotates in the direction (Ab) in which the sheet is wounded is smaller than the tension applied to the sheet by the rotation shaft when the rotation shaft rotate in the direction (Af) in which the sheet is fed in. |
