Claim Text:
1. A transportation device comprising: a first roller that transports a sheet-shaped medium from an upstream side to a downstream side in a transporting direction along a transporting passage; a guide member that has a base end and a guide section extended along the transporting direction, wherein the guide member is arranged upstream of the first roller in the transporting direction, the base end being upstream of the guide section and the first roller in the transporting direction and the guide section oscillates about the base end; and a second roller that is paired with the first roller and wherein the second roller is movable between a correcting position where the second roller pinches the sheet-shaped medium with the first roller and corrects a curl of the sheet-shaped medium, and a standby position where the second roller separates from the transporting passage, a rotational axis about which the guide section oscillates and a rotational axis about which the second roller pivots from the correcting position to the standby position are positioned on opposite sides of a rotational axis of the first roller in the transporting direction, with both the rotational axis for the guide section and the rotational axis for the second roller being below the transporting passage and the rotational axis of the first roller, wherein movement of the guide member is synchronized with movement of the second roller between the correcting position and the standby position such that the guide member moves to an escaping position where the guide member is separated from the transporting passage when the second roller moves to the correcting position and wherein the guide member includes a flat surface that is configured to support and guide a surface of the sheet-shaped medium in the transporting passage in a guide position where the guide member is not separated from the transporting passage when the second roller is in the standby position.
