PRINTER PLATEN ASSEMBLY FOR HANDHELD PRINTER

摘要

A self-adjusting printing assembly for accommodating generally planar media of differing thickness comprising a printing head for placement of indicia on sa id media, a guide assembly positioned adjacent said printing head for guiding said media to said printing head. The guide assembly includes a planar platen for continuou sly supporting one surface of said planar media and a planar shield member fixedly supported with respect to said platen for continuously supporting said surface o f said planar media. The assembly also includes means for movably mounting said platen with respect to said shield for movement in a direction toward and away from sai d planar shield while maintaining said planar platen generally parallel to said sh ield for accommodating said media of differing thickness, and a drive means for urging sa id media through said guide assembly and towards said printing head.
