Patent ID: 7128318

Claim:
A sheet edge registration system with improved sheet deskewing for flimsy print media sheets, in which a sheet moving in a sheet movement direction is partially buckled by at least one edge of said sheet engaging said registration system, wherein a transversely pivotal baffle member is pivotally mounted to overlie at least part of said buckled sheet being buckled by said sheet edge registration system and to at least partially define a sheet buckle chamber for said buckled sheet, said pivotal baffle member being intermediately pivotable about a pivot axis extending generally in said sheet movement direction and generally intermediately of said sheet so as to provide a first side of said pivotal baffle member extending out over at least a substantial portion of one side of said sheet from one side of said pivot axis, and a second side of said baffle member extending out over at least a substantial portion of the opposing side of said sheet from the opposite side of said pivot axis, so that pivotal movement of said second side of said baffle member in a direction away from said sheet is automatically opposite from pivotal movement of said first side of said baffle member in a direction towards said sheet, so that the effective buckle chamber size and sheet path length on one side of said sheet is automatically different from the effective buckle chamber size and sheet path length on the other side of said sheet from said pivoting of said pivotal baffle member, so as to assist in the deskewing of said sheet being partially buckled by said sheet edge registration system.
