Abstract
A postage meter has a print drum assembly which includes a print drum and a drum shaft. The drum includes selectively settable value printing elements. The drum shaft has, located in one or more grooves therein, a plurality of linearly movable racks. These racks are connected to the value printing elements in such a manner that linear movement of one rack alters the position of a corresponding value printing element. The meter also has a plurality of gears, called cross-over gears, arranged to drive corresponding racks. The cross-over gears driving the racks in the or each groove are arranged side-by-side and are independently driven by respective drive components arranged for rotation about a rotation axis common to the cross-over gears and the drive components.
