ABSTRACT:
A pivotable mounting assembly for a thermal print head enables the print head to spherically pivot with respect to its associated support arm. The print head is attached to a mounting head and an associated support arm is attached to a cantilever support. A spherical bearing assembly interconnects the mounting head with the support arm and enables the print head to spherically pivot with respect to the support arm. The spherical bearing connection equalizes tangential pressure when the print head is biased against a platen roller. The mounting assembly further includes sub-assemblies for adjusting the rotational and front-to-back alignment of the print head dot line with respect to the support arm, as well as the side-to-side registration of the dot line.
