To provide a medium transport device which can transport a medium more appropriately, a control method and a control program.SOLUTION: A medium transport device 100 has: plural feed rollers 112 which are located at intervals in a direction orthogonal to a medium transport direction, and respectively rotate independently and feed a medium; a center sensor 115 which is located on a downstream side with respect to the feed roller and at a midship part, and detects the fed medium; plural side sensors 116, 117 which are located at a position same as that of the center sensor or on a downstream side with respect to the center sensor and on both sides of the center sensor, and respectively detect the fed medium; and a control part 171 which differs peripheral speeds of the plural feed rollers from one another until at least the center sensor detects the medium in the case that the center sensor does not detect a medium within a prescribed time after any one of the plural side sensors has detected the medium.SELECTED DRAWING: Figure 10 【課題】媒体をより適切に搬送させることが可能な媒体搬送装置、制御方法及び制御プログラムを提供する。【解決手段】媒体搬送装置１００は、媒体搬送方向と直交する方向に間隔を空けて配置され、それぞれ独立に回転して媒体を給送する複数の給送ローラ１１２と、給送ローラより下流側に且つ中央部に配置され、給送された媒体を検出するセンターセンサ１１５と、センターセンサと同一位置又はセンターセンサより下流側に且つセンターセンサの両側に配置され、それぞれ給送された媒体を検出する複数のサイドセンサ１１６、１１７と、複数のサイドセンサの内の何れかが媒体を検出してから所定時間内にセンターセンサが媒体を検出しない場合、少なくともセンターセンサが媒体を検出するまで複数の給送ローラの周速度を相互に異ならせる制御部１７１と、を有する。【選択図】図１０
