ABSTRACT:
A driver for positioning the postage amount handles of a postage meter, the driver including motors which, in response to control signals from a postage computer, axially displace shafts along paths generally parallel to the paths of the postage meter handles. The shafts support actuator fingers which couple the shaft movement to the respective handles. An optical interruptor for each shaft senses various shaft positions and provides signals to the postage computer which are used in part to develop the control signals.
