A post-processing device includes a first discharge unit, a processing tray, an end alignment portion, a transport unit that comes into contact with an upperface of a medium placed on the processing tray and transports the medium to the end alignment portion, a position changing unit that changes the relative position of the transport unit with respect to the processing tray, a controller, 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 the processing information related to the process performed on the medium, and wherein the processing information includes information about a process performed on the first medium.

A post-processing apparatus includes a first discharge section configured to discharge a medium having thereon information recorded by a recording section, a processing tray configured to be loaded with the medium discharged by the first discharge section, an edge alignment section disposed on the processing tray, a transport section making contact with an upper surface of the medium mounted on the processing tray and configured to transport the medium to the edge alignment section, a position change section configured to change a relative position of the transport section with respect to the processing tray, and a controller configured to change pressure of when the transport section presses the medium by controlling the position change section, and a post-processing section configured to perform post-processing on the medium on the processing tray, wherein the controller changes the pressure based on processing information regarding processing to be performed on the medium.

The apparatus includes a first ejection unit, a processing tray, a blower unit, a control unit, and a post-processing unit. The first ejection unit ejects a medium recorded by ejection of a liquid. On the processing tray, the medium ejected by the first ejection unit is stacked. The blower unit blows air to the medium stacked on the processing tray. The control unit controls the blower unit. The post-processing unit post-processes the medium stacked on the processing tray. Based on processing information about processing performed on the medium, the control unit changes a blowing amount at which the blower unit blows air.

A sheet stacking apparatus includes a frame, a round member directly or indirectly connected to the frame, and an arm directly or indirectly connected to the frame. The arm is rotatable to rotate between a first position and a second position. The arm is positioned to bias sheets toward the round member when in the first position, and the arm is positioned to bias the sheets away from the round member when in the second position.

A post-processing apparatus includes a transport path having a first path member and a second path member, a punching member disposed on the transport path to perform punching on the medium. The transport path includes a first transport path disposed downstream of the punching member in a transport direction and a second transport path continuously extending downstream of the first transport path in the transport path, the second transport path having a curved shape to hold the medium in a curved state, the first path member in the second transport path forms an outer side of the curved shape and is disposed at a position further separated from the first surface than the first path member in the first transport path, and an upstream end in the transport direction of the medium in the curved state is moved from the first transport path to the second transport path.

A medium loading device includes a side end aligning member which is positioned at a standby position when a medium is ejected; and a control section. When a value based on first information relating to recording density of a medium to be ejected this time and at least one medium among the media ejected previously is equal to or greater than a threshold value, the control section specifies a first position, which overlaps the medium to be ejected this time, as the standby position, and when the value based on the first information is less than the threshold value, the control section specifies a second position, which does not overlap the medium to be ejected this time, as the standby position, and the control section adjusts the threshold value based on second information relating to at least one medium among the media recorded before the ejection at this time.
