Abstract
Actuator for operating the arcuately moving levers of a postal meter in accordance with output signals from a computing postal scale. The actuator includes drive shoes which engage the levers and are driven along a linear path generally parallel to the arcuate path of the levers. The drive shoes are advanced and retracted by lead screws driven by stepping motors to move the levers in incremental steps. Position encoders provide signals indicative of the positions of the levers, and these signals are combined with the signals from the scale to control the operation of the actuator.
