A reception apparatus that receives an article discharged from a processing apparatus includes a first rod, a second rod, a reception sheet and two side rods. The reception sheet has flexibility, is supported by the first rod and the second rod and receives the article between the first rod and the second rod. The two side rods can rotate, extend and contract independently from each other with respect to the processing apparatus while respectively supporting both end portions of the second rod.

A reception apparatus that receives an article discharged from a processing apparatus includes a first rod, second rod and a reception sheet. The first rod extends in a direction crossing a direction of the discharge below a discharge port of the processing apparatus in a gravity direction. The second rod extends in the direction crossing the direction of the discharge at a position farther away from the discharge port than the first rod. The reception sheet has flexibility, is supported by the first rod and the second rod, and receives the article discharged between the first rod and the second rod. The first rod is capable of being disposed at a first position and a second position which are different from each other in the gravity direction.

In a post-processing device (sheet discharge device), a pile thickness calculating section calculates, from a type and the number of paper sheets discharged through a sheet output port, a thickness of a pile, at its leading end, of sets of paper sheets on a sheet output tray (piling section), calculates a thickness of the pile, at its trailing end, of sets of paper sheets on the sheet output tray from an amount of movement of a lifting section, and calculates an angle of inclination of the uppermost set of paper sheets in the pile from the thicknesses of the pile at its leading and trailing ends, a height of inclination of the sheet output tray, and a length of the paper sheets. The control section controls the sheet discharge section to change a manner of discharging a subsequent set of paper sheets according to the calculated angle of inclination.

A sheet sorting apparatus includes a discharge port through which sheets are discharged, a stacking tray on which the sheets discharged from the discharge port are stacked, a sheet sorting member provided on a stacking surface on which the sheets of the stacking tray are stacked, and an operation mechanism for operating the sheet sorting member. The sheet sorting member is provided to be able to rise from the stacking surface by employing one end of the sheet sorting member as a pivot point, at a position at which the sheets fall from the discharge port. The sheet sorting member rises from the stacking surface by the operation mechanism, thereby forming an inclined surface, guiding the sheets placed on the inclined surface along the inclined surface, and shifting the sheets stacked on the stacking tray to a discharge direction of the sheets and a direction perpendicular to the discharge direction.

An image forming apparatus includes an image forming portion, a sheet discharging portion, and a sheet stacking portion. The stacking portion includes a first member including an inclined surface inclined upward toward a downstream side of a sheet discharging direction, and a second member including a stacking surface which projects upward from the inclined surface and on which the discharged sheet is stacked. The second member is rotatable relative to the first member about a supporting point provided upstream of the stacking surface with respect to the sheet discharging direction. The second member is rotatable about the supporting point in a direction in which the stacking surface moves downward in accordance with an increase in number of sheets stacked on the stacking surface.
