Sheet sorter with stapler.

摘要

A sheet sorting apparatus (1) with a stapler (45) includes a plurality of bin trays (B); bin tray shifting device for moving the plurality of the bin trays (B) stepwisely substantially in the vertical direction to oppose the respective bin trays to a sheet inlet (10) of the sorting apparatus (1), while expanding the clearances between the bin tray opposed to the sheet inlet (10) and an upper adjacent bin tray and between the bin tray opposed to the sheet inlet and a lower adjacent bin tray to provide a larger clearance than the predetermined clearances; and stapler (45), disposed substantially on an extension of the inclined sheet receiving surface and having a stapling head (45A) movable to above the sheet receiving surface and an anvil movable to below the sheet receiving surface, for stapling the sheets interposed between the stapling head (45A) and the anvil, wherein the bin trays are so disposed that between those ends of adjacent ones of the bin trays which are closer to the sheet inlet are deviated when seen in a direction substantially perpendicular to the sheet receiving surface, and wherein the stapling head (45A) is moved using a space provided by the deviation, and wherein the expanded clearance is smaller than a height of the stapling head (45A).
