1. A post-processing device comprising:
a discharge unit that discharges a medium on which a liquid is ejected and recording is performed;
a processing tray on which the medium discharged by the discharge unit is placed;
an end alignment portion that is provided on the processing tray and aligns an end of the medium;
a transport unit that comes into contact with an upperface of the medium placed on the processing tray and transports the medium to the end alignment portion;
a position changing unit that changes a relative position of the transport unit with respect to the processing tray;
a controller that controls the position changing unit; and
a post-processing unit that performs a post-process on the medium on the processing tray, wherein
the position changing unit is configured to move the transport unit to a transport position to which the medium is transported and a standby position farther away from the processing tray than the transport position, wherein
the controller changes the standby position based on processing information about a process performed on the medium, and wherein
the processing information includes, among a first medium after alignment and a second medium before alignment, information about a process performed on the first medium.
