Claim Text:
1. A conveyance device, comprising: a first conveyance unit that conveys a medium while fixing a first surface of the medium, configured to convey the medium along an arc-shaped path at a transfer position at which the medium is transferred to the downstream side in a conveyance direction in which the medium is conveyed; a second conveyance unit that is disposed on the downstream side of the first conveyance unit in the conveyance direction and includes a holding unit holding a leading end portion of the medium transferred from the first conveyance unit at the transfer position, configured to convey the medium transferred at the transfer position along the arc-shaped path on condition that a portion of the path is disposed at a position at which the portion of the path leads to the first conveyance unit side from the transfer position; a blowing unit that is disposed on the second conveyance unit side from the transfer position and blows air from the second conveyance unit side to the first conveyance unit side on the downstream side of the transfer position in the conveyance direction, configured to blow air toward the medium conveyed by the second conveyance unit; and wherein the blowing unit blows air to the downstream side in the conveyance direction at a range within 15°, based on a line which connects a rotation center of the first conveyance unit and a rotation center of the second conveyance unit, the conveyance device further including: a medium information acquisition unit that acquires information of the medium including at least one of a thickness and stiffness of the medium; and a blowing control unit that controls an operation of the blowing unit, wherein the blowing control unit relatively decreases an amount of air blown from the blowing unit with respect to a medium having a relatively thin thickness and relatively increases an amount of air blown from the blowing unit with respect to a medium having a relatively thick thickness, according to the acquired information of the medium, and wherein the blowing control unit relatively decreases an amount of air blown from the blowing unit with respect to a medium having relatively low stiffness and relatively increases an amount of air blown from the blowing unit with respect to a medium having a relatively high stiffness, according to the acquired information of the medium.
