Claim 11:
12. A conveyance device comprising:
a supply unit configured to supply a long medium;
a conveyer having a pair of rollers rotating around an axis extending in an axial direction, the conveyer being configured to nip and to convey, with the pair of rollers, the medium in a conveyance direction from the supply unit toward a print unit configured to print an image on the medium, the conveyer being positioned upstream of the print unit in the conveyance direction;
a tensioner configured to contact a second surface of the medium on a side opposite a first surface of the medium on which the image is printed by the print unit, causing the medium to bend, and to apply tension to the medium, the tensioner being disposed above the supply unit, and being pivotably supported around an axis extending in the axial direction, at a position upstream of the conveyer in the conveyance direction; and
a rotor rotatably supported around an axis extending in the axial direction, the rotor being positioned upstream of the conveyer in the conveyance direction, and positioned downstream, in the conveyance direction, of an upstream end portion, in the conveyance direction, of the tensioner, the rotor being positioned such that an upper end of the rotor and a nipped point where the medium is to be sandwiched between the pair of rollers are at a same height, the rotor being configured to contact the second surface of the medium, wherein
the tensioner has a pivot shaft, a pivot member, and an urging member, the pivot shaft extending in the axial direction, the pivot member being rotatably supported around the pivot shaft, and having an outer peripheral surface configured to contact the second surface, the urging member urging the pivot member toward a side on which the medium is to be arranged, and
the rotor is provided separately from the pivot shaft, and is positioned downstream of the pivot shaft in the conveyance direction,
a first distance between a rotational center of the pivot shaft and a rotational center of the rotor is shorter than a second distance between a rotational center of a first roller of the pair of rollers and the rotational center of the rotor, the first roller being configured to contact the second surface of the medium.
