Abstract: A bookbinding device and a print-medium post-treatment apparatus having the same. In the bookbinding device, when a print medium drops and is loaded a stack plate, a drop position of a leading end of the print medium is changed according to a size of the print medium. This prevents sequence upset of print media when the print media are stacked one above another on the stack plate.

Abstract: A print-medium post-treatment apparatus and a control method thereof, to increase the number of print media stacked on a bookbinding stack tray by controlling operation of a conveyor belt. The a print-medium post-treatment apparatus includes a bookbinding stack tray including a tray sensor to sense a print medium and a conveyor belt to move the print medium, and a controller to move the print medium in a given discharge direction by operating the conveyor belt in a first direction if the tray sensor senses the print medium moved onto the bookbinding stack tray and to move the print medium in an opposite direction of the discharge direction by operating the conveyor belt in a second direction so as to reduce a distance between a previously discharged print medium and a subsequently discharged print medium.

Abstract: Disclosed is a print-medium post-treatment apparatus, in which a converting guide to guide a print medium to any one of a first delivery path and a second delivery path is operated upon receiving rotational force from a delivery motor for delivery of the print medium. This enables omission of a drive device to operate the converting guide.
