Abstract
An arrangement for adaptively driving the flag element of a document handling device, such as a document sorter. The invention uses a force generating mechanism to produce torque at the periphery of a cam. A flexible connector that is wrapped around the cam is used to pull the flag element. The cam is shaped such that the force exerted on the flag element produced by constant torque varies in accordance with the size of the document stack in the hopper of the document handling device.
