<p>The invention concerns a thermal printing device capable of being closed by clipping. The inventive device comprises a thermal printhead (2), a roller (4) integral with a gear assembly, whereon rests the printhead (2) when the device is in printing position and two orifices (6, 7) on each lateral flank of the frame. The invention is characterised in that the portion of the orifices (6) and (7) opposite the printhead is so configured as to present an unstable equilibrium position of the roller while its axis is moving in said orifices (6, 7) when it is subjected to the pressure of the printhead. The invention is applicable to compact devices.</p> |
