Abstract
The invention relates to a thermal printing mechanism, comprising a chassis (1) housing a motor (6) for driving a printable tape, a thermal printing head (4), a backup roller (5) and electronic control means (8). The chassis (1) is fitted with a rigidification plate (9) extending substantially over its length, said plate being made of metal, forms a motor supporting bracket (6) to which it is welded, to provide heat sinking means. Said plate (9) is moreover operated to support a spring for pushing the printing head (4) towards the back-up roller (5). The mechanism is controlled electronically by a flexible connector (8) which is linked to remote control means of the mechanism, and which is besides operated for evacuating the electrostatic charges.
Claims12
A thermal printing mechanism, comprising a chassis housing mainly a printable tape driving means, a thermal printing head, means for contacting the tape against the printing head, and electronic means for controlling the dynamic members of the mechanisms, the tape driving means comprising a motor for driving the reserve of a tape roller, the latter circulating between the printing head and a back-up roller driven into rotation by the motor, the means for contacting the tape against the printing head comprising an elastic member for pushing the printing head towards the back-up roller, the chassis being fitted with a rigidification plate extending substantially over its length, which is rendered interconnected and immobilised on the chassis in translation as well as in pivoting around itself, wherein the motor is fixed by heat exchanging means to the rigidification plate, which as a metal plate, forms means for sinking the heat generated by the motor.
