Medium transport device, post-processing device, and recording apparatus

A medium transport device comprising:

• a guide member that supports and guides a medium transported in a transport direction;
• a stacking section having an alignment section that aligns upstream end in the transport direction of a medium bundle composed of a plurality of media supported and guided by the guide member, the stacking section being configured so that a plurality of the media are stacked thereon;
• a feeding section having a feeding member formed of an elastic material, and the feeding section being configured to rotate to feed the medium on the stacking section toward the alignment section;
• and
• a notch formed in the guide member at a region where the feeding member is disposed in a width direction of the guide member which intersects the transport direction, the notch being cut out toward upstream in the transport direction, wherein
• a rotation center of the feeding section is disposed at a position between the stacking section and the guide member such that a rotation locus of a distal end of the feeding member intersects the guide member when viewed in the width direction,
• an upstream end of the notch in the transport direction is formed inside the rotation locus, and
• a cleaning unit that cleans the feeding member by contacting the feeding member is provided on the guide member at a position upstream from the notch in the transport direction on a surface opposite to that supporting the medium.

• a feeding section having a feeding member formed of an elastic material, and the feeding section being configured to rotate to feed the medium on the stacking section toward the alignment section, wherein
• the feeding member includes a shaft rotatable about an axial direction in the width direction, and at least one vane extending outward from the shaft, and
• the vane is positioned at a retracted position on an opposite side of the guide member to the medium when the medium is guided by the guide member;
• and
• a notch formed in the guide member at a region where the feeding member is disposed in a width direction of the guide member which intersects the transport direction, the notch being cut out toward upstream in the transport direction, wherein
• a rotation center of the feeding section is disposed at a position between the stacking section and the guide member such that a rotation locus of a distal end of the feeding member intersects the guide member when viewed in the width direction,
• an upstream end of the notch in the transport direction is formed inside the rotation locus, and
• the notch formed in the guide member penetrates the guide member from a bottom side to a top side such that a portion of the feeding member is able to pass through the guide member.
