Abstract (en)

The invention relates to the thermal printing device with the so called "easy-loading" system for the paper. Thermal printing mechanism comprising: a printer chassis (2), a thermal printhead (1), platen roller (3) having a conductive shaft (6), the platen roller (3) being designed to be movable between two possible positions - open, where the platen roller (3) is detached from the printer chassis (2) and printing position where the platen roller (3) is held in the printer chassis (2), and motion means (11) to put the platen roller (3) in rotation. It further comprises two lateral conductive contacts (4 and 5) arranged on the printer chassis (2) so as to be in a contact with the two opposite ends of the platen roller conductive shaft (6) in the printing position of the platen roller (3) for conducting electrical current, thus forming an electrical switch for indication of the status of the platen roller position.
