Abstract

Abstract Translated from German Es wird ein Thermodruckkopf (10) mit einem Gehäuse (12, 14, 16) beschrieben, in dem ein eine Thermodruckplatine (26) tragender Support (42) um eine an ihren beiden Enden gela­gerte Achse (28) schwenkbar gelagert ist. Die Thermodruck­platine (26) weist mehrere selektiv ansteuerbare, in einer Linie (36) angeordnete Heizelemente auf. In dem Gehäuse (12, 14, 16) ist eine Gegendruckwalze (22) um eine Achse (20) drehbar gelagert, mit der die Linie (36) der Heizelemente der Thermodruckplatine (26) längs einer achsparallelen Man­telinie kraftschlüssig in Anlage gehalten ist. Die Lager­achse (28) des Supports (42) verläuft parallel zur Achse der Gegendruckwalze (20) und im Abstand von dieser Achse (20). Ein Ende der Achse (28) des Supports (42) ist in dem Gehäuse (12, 14, 16) senkrecht zu der von der Achse (28) und der Linie (36) der Heizelemente gebildeten Ebene verstellbar ge­lagert. A thermal print head (10) with a housing (12, 14, 16) is described, in which a support (42) carrying a thermal print circuit board (26) is mounted so as to be pivotable about an axis (28) mounted at its two ends. The thermal printing board (26) has a plurality of selectively controllable heating elements arranged in a line (36). In the housing (12, 14, 16), a counter-pressure roller (22) is rotatably mounted about an axis (20), with which the line (36) of the heating elements of the thermal printing plate (26) is held in a force-fitting manner along an axis-parallel surface line. The bearing axis (28) of the support (42) runs parallel to the axis of the counter-pressure roller (20) and at a distance from this axis (20). One end of the axis (28) of the support (42) is adjustably mounted in the housing (12, 14, 16) perpendicular to the plane formed by the axis (28) and the line (36) of the heating elements.
