STACKING AND ALIGNING SYSTEM FOR HIGH CAPACITY SHEET, AND STACKING DEVICE FOR HIGH CAPACITY SHEET

摘要

PURPOSE: To provide a high capacity sheet stacking system for stacking a substantial quantity of continuous sheet output from a copying device. CONSTITUTION: This system 10 receives sheets 14 on a sheet stacking tray 18 with a sheet stacking surface 18a inclined at a substantial angle from a horizontal plane and aligns the sheets to an upstanding stack edge alignment surface. The stack edge alignment surface is automatically varied in height above the stacking surface with the change in stack height in the tray, in coordination with vertical repositioning of the sheet input level 20 to the tray with stack height, so that an elevator system is not required for the stacking tray, and a simple fixed position tray may be used, and yet high sheet stacking capacity is obtained.
