ABSTRACT:
A medium transport apparatus includes a feeding roller configured to rotate around a rotational axis. A guide rail extends along the rotational axis. A slider is supported by the guide rail and movable along the rotational axis. A rotatable pinch roller is configured to clamp medium between the feeding roller and the pinch roller to move the medium. A lever is connected to the pinch roller and movable to change a clamping state with respect to the medium between the feeding roller and the pinch roller. An arm is connected to the slider and configured to take an engaging position where the arm moves the lever to change the clamping state when the slider moves along the rotational axis and a standby position where the arm is not engaged with the lever when the slider moves along the rotational axis.
