PROBLEM TO BE SOLVED: To provide a decurling unit capable of decurling a large curl generated on a medium with a small space, and further to provide a liquid injection device provided with the decurling unit.SOLUTION: A decurling unit comprises: a transportation roller (19b) transporting a sheet P to which ink adheres; two shafts (61 and 62) having axis lines in a direction (X) intersecting with a transportation direction Y of the sheet P and being disposed so as to have an inter-shaft space SJ where the sheet P can pass through closer to an upstream side in the transportation direction Y of the sheet P than the transportation roller (19b); and a shaft moving section 60 moving at least one shaft of the two shafts (61 and 62) to an interchange direction being a direction where positions of the two shafts (61 and 62) are interchanged and a direction where being brought into contact with a medium in a direction intersecting with the transportation direction Y and intersecting with the direction of the axis lines after transportation of the sheet P by the transportation roller (19b) is started with the sheet P passing through the inter-shaft space SJ of the two shafts (61 and 62).SELECTED DRAWING: Figure 2 |
