Abstract

A spring loaded baffle or guide sheet deflector 1 pivotal about an axis 2 is provided to assist in the restacking of different thicknesses (weights) of document sheets 3 in a recirculating document handling unit tray or other sheet restacking applica-tion. As shown in Figure 1, the sheet 3 is driven in by spaced rollers 4, between which the baffle 1 is positioned. The baffle 1 is positioned and curved to both corrugate (bow) the sheet 3 and deflect it upwardly. A lighter sheet, which needs more deflection for restacking, is deflected more, whereas a thicker, heavier sheet, which needs it less, deflects the spring loaded baffle 1 down instead as shown in Figure 2. Thus, the stiffer or heavier sheet desirably re-enters the restacking tray at a different (lower) angle of tray entry trajectory than a lighter sheet.

VARIABLE SHEET DEFLECTOR FOR DOCUMENT RESTACKING (Cont'd)

A spring loaded baffle or guide sheet deflector 1 pivotal about an axis 2 is provided to assist in the restacking of different thicknesses (weights) of document sheets 3 in a recirculating document handling unit tray or other sheet restacking applica- tion. As shown in Figure 1, the sheet 3 is driven in by spaced rollers 4, between which the baffle 1 is positioned. The baffle 1 is positioned and curved to both corrugate (bow) the sheet 3 and deflect it upwardly. A lighter sheet, which needs more deflection for restacking, is deflected more, whereas a thicker, heavier sheet, which needs it less, deflects the spring loaded baffle 1 down instead as shown in Figure 2. Thus, the stiffer or heavier sheet desirably re-enters the restacking tray at a different (lower) angle of tray entry trajectory than a lighter sheet.

There are additionally provided flexible finger strips 5 for pushing down the trail edge area of a sheet after it has passed the baffle 1 to prevent the sheet from bouncing backwards out of the tray after it hits the front guide of the stack (not shown) and for assisting restacking (settling down) of the sheet.
