A medium-transport apparatus includes: an apparatus main body having the transport path for transporting the medium; and a cover CV provided on the side surface of the apparatus main body and configured to be switched between a first state of exposing the transport path and a second state of covering the transport path. The cover CV is divided into: a first cover that has the rotation shaft along a Z-axis and is rotatable with respect to the apparatus main body; and a second cover that is arranged on a −Z side of the first cover, has the rotation shaft along a Y-axis on the Z-side, and is rotatable with respect to the apparatus main body.
