Abstract

A thermal printing head (10) having a housing (12, 14, 16) is described wherein a support (42) carrying a thermal printing plate (26) is mounted to be pivotable about an axis (28) mounted on both of its ends. The thermal printing plate (26) comprises several selectively triggerable heating elements being arranged in a line (36). In the housing (12, 14, 16), a counter-pressure roll (22) is mounted to be rotatable about an axis (20) with respect to which the line (36) heating elements of the thermal printing plate (26) is held in frictional contact along a paraxial generating line. The mounting axis (28) of the support (42) extends to be parallel with respect to the axis of the counter-pressure roll (20) and to be spaced apart from this axis (20). One end of the axis (28) of the support (42) is mounted in the housing (12, 14, 16) to be adjustable in perpendicular direction with respect to the plane formed by the axis (28) and the line (36) of the heating elements.
