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.
L'invention concerne un dispositif d'impression thermique pouvant se fermer par clipsage. Le dispositif selon l'invention comprend une tête d'impression thermique (2), d'un rouleau (4) solidaire d'un engrenage, sur lequel repose la tête d'impression (2) lorsque le dispositif est en position d'impression et de deux lumières (6, 7) sur chaque flanc latéral du châssis, caractérisé en ce que la partie des lumières (6 et 7) opposée à la tête d'impression a une configuration telle qu'elle présente une position d'équilibre instable du rouleau pendant le déplacement de son axe dans lesdites lumières (6, 7) lorsqu'il subit la pression de la tête d'impression. Application à des dispositifs compacts.
