Publication number: 20160052744Abstract: A sheet discharge mechanism according to an embodiment includes a tray with a loading surface on which discharged sheets are loaded. An alignment plate extends from a downstream side of the loading surface in a sheet discharge direction. An alignment roller contacts an uppermost sheet loaded on the loading surface at a predetermined position, and rotates while contacting the uppermost sheet to align the sheets against the alignment plate. A support mechanism elastically supports the tray so that at least a portion of the tray around the predetermined position moves downward in accordance with an increase in weight of sheets loaded on the loading surface. A height adjustment mechanism maintains a minimum height of sheets when the portion of the tray around the predetermined position moves downward by a predetermined distance or more in accordance with the increase in weight of sheets loaded on the loading surface.Type: ApplicationFiled: August 21, 2014Publication date: February 25, 2016Inventor: KIKUO MIZUTANI
