Abstract:
A sheet post-processing device, comprising:a post-processing tray on which sheets of paper supplied from an image forming device are stacked; a post-processing section for applying a post-processing operation to edges of one side of the sheets of paper stacked on said post-processing tray; a first feed-out opening for discharging, to outside, the sheets of paper having been subject to the post-processing operation; a first discharge transport path for transporting the sheets of paper from said post-processing tray to said first feed-out opening; and a feed-out section for discharging the post-processed sheets of paper from said post-processing tray to said first discharge transport path, wherein said post-processing tray has an adjusting-moving section for adjusting said stacked sheet of paper, moving the adjusted sheets of paper to a post-processing position at which a post-processing operation by said post-processing section can be applied, and moving said post-processed sheets of paper to a discharge position at which a discharging operation by said feed-out section is applied, said adjusting-moving section includes a sheet supporting member which adjusts lower edges of the sheets of paper stacked on said post-processing tray, and slides on said post-processing tray while carrying the sheets of paper thereon so that the sheets of paper are moved to the post-processing position and the discharge position, and said feed-out section has a switching gate for guiding the sheets of paper to either the post-processing position or the discharge position when said sheet supporting member is positioned in the post-processing position or the discharge position.
