Abstract
An arrangement for adaptively driving the flag element of a document-handling device, such as a document sorter. The rotation of a first cam exerts a first force on the flag element. The profile of the first cam is such that the first force exerted on the flag element varies in accordance with the size of the document stack of the document-handling device. Alternatively, a second cam, rotatably connected to the first cam, causes a rotation of the first cam such that the first cam exerts a second force on the flag element. The first cam is shaped such that the second force exerted on the flag element is constant.
