Abstract
A postage meter has a print drum with print wheels which are shiftable to select the value of the postage. The positions of the print wheels are controlled by the positions of rack gears. The racks are displaced by a pinion which is shifted from rack to rack. The racks are arranged in an arcuate or part annular array around the pinion.
