Abstract
Apparatus for holding a stack of sheets for entry into a sheet feeder, wherein there is provided a tray for vertically supporting the stack, left and right guide elements moveable toward and away from the lateral edges of the stack for centering the stack in the tray, and a flexible band formed in a loop, the band being attached to the guide elements at two locations, such that the guide elements move inward and outward laterally in unison, and the band being supported beneath the tray, and wherein the band is bent (e.g., around a convex surface) during inward movement of the guide elements so that when the movement stops the band tends to move the guide elements outwardly as it assumes an equilibrium position, thereby preventing overtightening of the guide elements against the stack.
