Abstract
Apparatus for feeding sheets seriatim from a stack of sheets which substantially prevents image ruboff. Such sheet feed apparatus includes a tray for supporting a stack of sheets. A plate associated with the tray supports the lead edge of the sheet stack. A major portion of the sheet stack, measured from the top of the sheet stack at the lead edge of the sheet stack, is supported by a mechanism associated with the plate. A positive flow of air is directed at a minor portion of the sheet stack, measured from the bottom of the sheet stack at the lead edge of the sheet stack, to enable the minor portion of the sheet stack to be levitated for separation of the sheets in the minor portion of the sheet stack. Sheets are selectively removed seriatim from the bottom of the sheet stack to feed such sheets away from the sheet stack, whereby as a number of sheets are removed from the minor portion of the stack, a substantially similar number of sheets are moved from the major portion of the sheet stack to the minor portions thereof.
