PROBLEM TO BE SOLVED: To provide a technique capable of enhancing controllability of transportation control while securing support properties of a belt-like base material during transportation.SOLUTION: A transportation unit transporting a belt-like base material in a longitudinal direction of the base material as a transportation direction comprises: a first driving roller capable of transporting the base material in the transportation direction by winding the base material and rotating; a second driving roller being disposed closer to a downstream side in the transportation direction than the first driving roller and capable of transporting the base material in the transportation direction by winding the base material and rotating; an inter-roller transportation path being provided between the first driving roller and the second driving roller, sagging the base material in a gravity direction and being capable of transporting the base material in a bent state; and a tension application section sucking a portion where the base material is bent from a lower side in the gravity direction and applying tension to the base material in the inter-roller transportation path.SELECTED DRAWING: Figure 1 |
