The present application is based on, and claims priority from JP Application Serial Number 2019-184341, filed Oct. 7, 2019, the disclosure of which is hereby incorporated by reference herein in its entirety.

BACKGROUND

1. Technical Field

The present disclosure relates to a medium transport device that transports a medium, a post-processing device having the medium transport device, and a recording apparatus having the post-processing device.

2. Related Art

There have been known apparatuses having a medium transport device that transports media such as sheets. JP-A-2010-6530 is an example of the related art. The post-processing device disclosed in JP-A-2010-6530 has a configuration in which paper sheets, which are outputted from an output transport path onto a stack tray, are then transported by a rotating paddle.

According to the configuration disclosed in JP-A-2010-6530, which includes a guide member that guides a medium to a stacking section and a feeding member that feeds the medium in the stacking section toward an alignment section, transport of a medium may become unstable due to contact between the guide member and the rotating feeding member. In addition, when the feeding member is disengaged and released from the guide member, the feeding member irregularly vibrates. When such a feeding member comes into contact with the medium, the vibration is propagated to the medium, which may cause unstable feeding of the medium toward the alignment section.

SUMMARY

In order to solve the above problem, a medium transport device according to the present disclosure includes: 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 thereby 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, and an upstream end of the notch in the transport direction is formed inside the rotation locus.
