Abstract
Abstract A thermal printing postage meter comprising a base supporting a registration wall, a print deck. The registration wall supports a detachable mounted thermal ribbon cassette and a thermal print head. The thermal print head is mounted to the registration wall to extend over the deck to define a print station. A platen drive assembly is mounted to the base for biasing an envelope against the thermal print head and causing the envelope to traverse the thermal print head during a print cycle of the thermal meter under the influence of a drive motor responsive to a micro controller. The micro controller has a plurality of switches mounted to the registration wall of the postage meter. The cassette is comprised of a housing formed by a front and rear wall maintained in spaced apart relationship by a plurality of side walls. The rear wall of the housing includes a slot having an outwardly extending pin slidably mounted in the slot. The switches are mounted within an opening in the registration such that mounting of the cassette housing to the registration wall cause the pin to contact one of the switches depending on the position location of the pin in the slot. The micro controller is programmed to operate the print cycle speed at one of the speeds in response to which one of the switches actuated by the actuation means.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
147 words
An improved thermal printing apparatus, said printing apparatus having a base supporting a registration wall, said registration wall supporting a thermal ribbon cassette, a print deck, a thermal print head mounted to the registration wall and extending over the deck to define a print station, a platen drive assembly is mounted in said base for biasing an envelope against the thermal print head and causing the envelope to traverse the thermal print head during a print cycle of the thermal printing apparatus having a drive motor responsive to a micro controller, the improvement comprising; said micro controller being programmable and programmed to operate said drive motor of said platen assembly at a plurality of operating speeds, said micro controller being further programmed to synchronously actuate said thermal print head, selection means for selectively causing said micro controller to select one of a plurality of print cycle speeds.
Claim 2
Dependent Claim
147 words
An improved thermal printing apparatus, said printing apparatus having a base supporting a registration wall, said registration wall supporting a thermal ribbon cassette, a print deck, a thermal print head mounted to the registration wall and extending over the deck to define a print station, a platen drive assembly is mounted in said base for biasing an envelope against the thermal print head and causing the envelope to traverse the thermal print head during a print cycle of the thermal printing apparatus having a drive motor responsive to a micro controller, the improvement comprising; said micro controller being programmable and programmed to operate said drive motor of said platen assembly at a plurality of operating speeds, said micro controller being further programmed to synchronously actuate said thermal print head, selection means for selectively causing said micro controller to select one of a plurality of print cycle speeds.
Claim 3
Dependent Claim
83 words
An improved thermal printing apparatus as claimed in claim 1 wherein said selection means comprises: said micro controller having a plurality of switches mounted in said printing apparatus; said thermal ribbon cassette having actuation means positionable to actuate one of said plurality switches when said thermal ribbon cassette is mounted to said registration wall; said micro controller to operate said platen roller assembly at one of a plurality of spaces in response to which one of said switches actuated by said actuation means.
Claim 4
Dependent Claim
104 words
An improved thermal printing apparatus as claimed in claim 2 wherein said actuation of said thermal ribbon cassette includes: said cassette having a housing formed by a front and rear wall maintained in spaced apart relationship by a plurality of side walls, said rear wall of said housing having a slot; a outwardly extending pin slidably mounted in said slot; said plurality of switches being mounted within an opening in said registration wall such that mounting of said cassette housing to said registration wall causes said pin to contact one of said switches depending on the position location of said pin in said slot.
