Claim:
An apparatus for transporting a medium, comprising: a flat supporting member, defining a transporting path adapted to support the medium thereon; a detection roller, opposing the flat supporting member, the detection roller being adapted to be directly brought into contact with the medium and to be rotated in accordance with the transportation of the medium; a detector, which detects a rotation amount of the detection roller; a controller, which controls the transportation of the medium in accordance with the rotation amount; a first roller, which transports the medium toward the transporting path; and a second roller, which ejects the medium transported from the transporting path to outside of the apparatus, and an urging member, which urges the detection roller toward flat supporting member, so that the detection roller is movable in a direction orthogonal to both of a direction that the medium is transported and an axial direction of the detection roller, wherein the detection roller is disposed between the first roller and the second roller.
