摘要:
The electronic postage meter includes a printing unit which is responsive to a plurality of motors for printing of a postage indicia in response to control circuit. The control circuit is comprised of a programmable microprocessor in bus communication with an accounting means having memory units for accounting for the postage printed by the printing unit responsive to the programming of the microprocessor. An integrated circuit includes an address decoding module means for generating a unique combination of ASIC control signals in response to a respective address placed on the bus by the microprocessor. A timer register is responsive to ones of the control signals from the address decoding module to enable writing of the timer data into the timer registers by the microprocessor. The timer unit is responsive to the timer data for generating one of a plurality of timing signal in accordance with timer data. The data also includes motor data. Prime motor register units are responsive to other ones of the control signals from the address decoding module to enable writing of the motor data into the timer registers by the microprocessor. A motor control unit is responsive to the motor data for generating a plurality of motor control signals in accordance with the motor data.
摘要:
A deterrent to counterfeiting of indicias on mailpieces is provided in a method and apparatus for implementing the printing of the indicia using a customized printhead or customized printer drivers such that the dots of the bit-mapped printing are produced by the printer in unevenly spaced rows or columns. The dot size may also be varied in accordance with data from the meter, printed value, variable data such as the date, and forensic data suitably encrypted. When the indicia is scanned, the variations are readily detectable and the information is easily extracted by Postal Authorities.

A postage meter comprises a non-volatile memory and a microcomputer in communication with the non-volatile memory. The microcomputer is operatively coupled to a stepper motor. The stepper motor includes a rotor and is arranged for positioning at least one printwheel of the postage meter. The non-volatile memory has stored therein a value corresponding to a predetermined pulse width required for pulsing a coil of the stepper motor to position the rotor to a final position between step positions. The microcomputer pulses the stepper motor coil with a pulse of the predetermined pulse with for bring the stepper motor rotor to a final position for positioning the printwheel.
摘要:
A method and system for accessing a non volatile memory for writing data therein, wherein the memory has a write accessing input. A control circuit produces successive enable signals, and a hardware device is connected to apply signal to the write accessing terminal of said memory only in response to a plurality of successive enable signals.

A postage meter has a print drum with print wheels which are shiftable to select the value of the postage. The print wheels are adjusted by displacing respective transmission members; e.g. gears, which are driven by a pinion which is shifted from gear to gear. Control means is provided for controlling the shifting of the pinion so that it is engaged during each value setting only with those gears whose print wheel requires adjustment from its previous setting.
