Platen roller assembly for thermal postage meter.

摘要

The platen roller assembly is particularly suited for a thermal printing postage meter having a base supporting a registration wall and a deck, and a thermal print head fixably mounted to said registration wall above a portion of said deck to define a print station. A linking assembly is mounted in the base for rotatively supporting a platen roller in a home position below said deck when an envelope is to be received at said print station and biasing said platen in a second position above said deck in the direction of said thermal print head through an aperture in said deck during a print cycle. An ejection plate fixably mounted to said registration wall above said deck longitudinally in line with said thermal print head. The linking assembly further rotatively supports an ejection roller in a home position biasing against said ejection plate through an aperture in said deck when said platen roller is in the home position principle for ejecting an envelope after completion of the print cycle and rotatively supporting said ejection roller in a second position below said deck during a print cycle. <IMAGE>
