Postage meter system for communicating platen movement to a microprocessor to signal completion of printing

摘要

The invention has particular utility when utilized in a stand-alone electronic mailing machine of the reciprocating platen type. The entire drive mechanism, setting mechanism, and control devices as well as the postage metering mechanisms are all contained in one housing so that there is no need for a separate base. A single central processing unit is utilized along with memory for the purpose of accounting for the postage value that has been charged into the mailing machine as well as the amount that has been used. A pair of stepper motors is used for the purpose of adjusting the print dies with the amounts that are to be imprinted. One of the stepper motors is also used to trip a single revolution clutch which is utilized to affect the printing operation.
