Plural mode stacking system for slit sheets

In a reproduction system with an output system having an output sheet stacking tray system, said output system further having a slitter with selectable sheet slitting positions in which printed sheets being outputted by said reproduction system into said output system are selectably unslit or slit in their sheet output direction by said slitter into plural slit sheets of selectably variable sheet widths and stacked in said output sheet stacking tray system, which output sheet stacking tray system includes a sheet stacking surface member;

• the improvement comprising:
• said sheet stacking surface member being flexible for selective repositioning into plural sheet stacking sections having plural differently angled sheet stacking surfaces,
• said output sheet stacking tray system further including a repositionable support system supporting said sheet stacking surface member for selectively forming said differently angled sheet stacking surfaces to provide a dual mode output sheet stacking tray system which is selectably convertible between a single sheet stacking position surface mode, wherein said sheet stacking surface is substantially planer for stacking unslit sheets thereon, and a plural slit sheet stacking surfaces mode wherein said sheet stacking surface is repositioned by said repositional support system into said plural sheet stacking sections having said plural differently angled sheet stacking surfaces, wherein in said plural slit sheet stacking surfaces mode said output sheet stacking tray system selectively provides plural said sheet stacking surfaces which are selectably variable in width for cooperation with the selectable sheet slitting position slitter to provide separate stacking of said plural slit sheets on respective said plural sheet stacking surfaces;
• wherein said repositionable support system comprises a bial bar extending longitudinally under and supporting said flexible sheet stacking surface member, and wherein said bail bar is movably mounted for movement in a transverse direction for alignment with said selectable sheet slitting positions.
