1. A media processing apparatus comprising:
a transporter that transports media;
a stacking portion on which the media transported by the transporter are stacked;
a binder that binds an upstream end portion of a media bundle in a transport direction of the media, the media bundle being a bundle of the media stacked in the stacking tray;
a pair of ejection rollers that eject the media bundle downstream in the transport direction by nipping the media bundle, the upstream end portion of the media bundle is bound, and by rotating;
a displacement mechanism comprising a swing unit that displaces a first roller of the pair of ejection rollers to a nipping position at which the media bundle is nipped and a separated position at which the first roller is separated from the media bundle; and
a control portion comprising a controller that controls at least the pair of ejection rollers and the displacement mechanism, wherein
the control portion, when the media bundle, the upstream end portion of the media bundle is bound, is to be ejected from the stacking tray, disposes the first roller at the nipping position and starts ejection of the media bundle, displaces the first roller to the separated position during ejection of the media bundle, and thereafter, disposes the first roller again at the nipping position to perform ejection of the media bundle,
wherein the transport direction in the stacking portion is the same direction as an ejection direction in which the pair of ejection rollers ejects the media bundle,
when viewed from the ejection direction, the nipping position of the media bundle nipped by the pair of ejection rollers overlaps a position at which the binder performs a binding processing operation on the media bundle,
wherein
the stacking portion has
a stacking surface on which the media bundle is stacked in an orientation in which the media bundle is inclined upward from upstream to downstream in the transport direction and
a reverse movement suppressing portion that suppresses reverse movement of the media bundle stacked on the stacking surface from downstream to upstream in the transport direction, and
the control portion controls the reverse movement suppressing portion to suppress reverse movement of the media bundle when displacing the first roller to the separated position during ejection of the media bundle,
wherein
the reverse movement suppressing portion is a pressing member that presses the media bundle toward the stacking surface, and
the control portion controls the pressing member to press the media bundle toward the stacking surface when displacing the first roller to the separated position during ejection of the media bundle.
