Abstract: A medium feeding apparatus includes a medium supporting portion supporting a medium, a feeding roller that feeds the medium, a separation portion configured to advance and retreat with respect to the feeding roller, a path forming member that is a member positioned upstream in a medium feeding direction with respect to a contact position between the feeding roller and the separation portion, that is configured to advance and retreat with respect to the feeding roller, and that is configured to narrow a medium feeding path directed toward the contact position, and a first pressing portion pressing the path forming member toward the feeding roller, in which the path forming member displaces the separation portion in a direction away from the feeding roller when the path forming member is pushed down in a direction retreating from the feeding roller by a medium having a thickness exceeding a predetermined thickness.

Abstract: A control unit of an image reading apparatus acquires, at an upstream position in a medium transportation direction of an abnormality determination area set for a leading-edge area of a medium, a distance WL from a center position in a medium width direction intersecting with the medium transportation direction to one edge in the medium width direction and a distance WR from the center position to the other edge in the medium width direction, and compares a value R that is a ratio between the distance WL and the distance WR or a difference therebetween with a threshold R0 determined in advance.

Abstract: A medium transport apparatus includes a medium transport path through which a medium passes, a path state detection section configured to output a detection value corresponding to a state of the medium transport path, a control section configured to compare the detection value output by the path state detection section with a threshold value for the detection value and determine whether an abnormal condition has occurred in the medium transport path, and a storage configured to store history information including the detection value acquired in the past, in which the control section changes the threshold value based on the history information.

Abstract: A printer includes a cap unit, a transporting driving roller, a power transmitting unit, and a pump. At least a part of each of the cap unit, the transporting driving roller, the power transmitting unit, and the pump has the same height in a height direction of the apparatus (a Z-axis direction) and the cap unit, the transporting driving roller, the power transmitting unit, and the pump are arranged along a direction (a Y-axis direction) intersecting with a rotational axis line direction (an X-axis direction) of the transporting driving roller. Therefore, it is possible to arrange so as to suppress each dimension of the cap unit, the transporting driving roller, the power transmitting unit, and the pump in a height direction and it is possible to contribute to the miniaturization of the apparatus.
