Summary:To provide a medium conveyance device capable of more appropriately correcting a skew of a medium, a control method and a control program.SOLUTION: A medium conveyance device 100 includes: a plurality of feeding rollers 112 which are arranged at intervals in a direction perpendicular to a medium conveyance direction and each independently rotate and feed a medium; a plurality of brake rollers 113 which are arranged so as to face each of the plurality of feeding rollers; a rotation shaft 135e of the plurality of brake rollers; a plurality of torque limiters 139a and 139b separately provided between each of the plurality of brake rollers; a skew detection part 164 which detects a skew of a medium to be fed; and a control part 161 which corrects the skew of the medium by making peripheral speeds of the plurality of feeding rollers mutually different when the skew of the medium is detected by the skew detection part.SELECTED DRAWING: Figure 7 【課題】媒体のスキューをより適切に補正す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、複数の給送ローラのそれぞれに対向して配置される複数のブレーキローラ113と、複数のブレーキローラの回転軸135eと、複数のブレーキローラのそれぞれとの間に、別個に設けられた複数のトルクリミッタ139a、bと、給送される媒体のスキューを検出するスキュー検出部164と、スキュー検出部によって媒体のスキューが検出された場合、複数の給送ローラの周速度を相互に異ならせることにより媒体のスキューを補正する制御部161と、を有する。【選択図】図7
