Patent ID: 7000541

Claim:
An apparatus for lifting at least one of a sheet of paper and a paper-like sheet, comprising: a first X-shaped member comprising a first beam and a second beam of substantially equal length rotatably connected to each other; a second X-shaped member comprising a first beam and a second beam of substantially equal length rotatably connected to each other; a rod having opposing ends respectively connected to said first and second X-shaped members; a first roller having an axle extending therethrough, wherein opposing ends of the axle contact the first beams; a second roller having an axle extending therethrough, wherein opposing ends of the axle contact the second beams; a first connecting rod having opposing ends that contact the first beams; a second connecting rod having opposing ends that contact the second beams; and at least one spring connected to said first and second connecting rods, said at least one spring providing a pinch force holding a surface of said first and second rollers in contact in an equilibrium position; wherein said first and second rollers rotate about their respective axles when moving apart from each other, and do not rotate about their respective axles when moving towards each other, the non-movement of said first and second rollers providing a friction force with respect to the sheet, causing a portion of the sheet to be interposed between roller surfaces when said first and second rollers return to the equilibrium position.
