Abstract
Abstract A sheet sorting apparatus (1) with a stapler (45) includes a plurality of bin trays (B) which are arranged substantially vertically with predetermined clearances between adjacent bin trays, which are inclined to provide an inclined sheet receiving surfaces and which are independently movable substantially in the vertical direction, wherein the bin trays (B) 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; 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 (B) to a sheet inlet (10) of the sorting apparatus (1); stapling device, 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; and a second shifting device for shifting the bin tray immediately above the bin tray opposed to the stapling device in a direction increasing the deviation, 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).
