Abstract

L'invention concerne un dispositif d'impression au moyen duquel il est possible d'éliminer une augmentation de la taille d'une cartouche et de modifier les vitesses de rotation d'un engrenage d'entrée et d'un engrenage de sortie. La présente invention porte sur un dispositif d'impression comportant un corps de dispositif d'impression et une cartouche d'impression pouvant être fixée au corps de dispositif d'impression et détachée de ce dernier. La cartouche d'impression est pourvue : d'une bande d'impression ayant une première extrémité et une seconde extrémité qui sont espacées dans un sens de largeur; d'un boîtier ayant une ouverture d'évacuation; d'un engrenage de sortie; d'un engrenage intermédiaire en prise avec l'engrenage de sortie; et d'un engrenage d'entrée en prise directe ou indirecte avec l'engrenage intermédiaire. L'engrenage de sortie et l'engrenage intermédiaire sont respectivement agencés dans des positions qui sont espacées de la bande d'impression dans le sens de la largeur au niveau de l'ouverture d'évacuation et qui sont plus proches de la première extrémité que de la seconde extrémité de la bande d'impression dans le sens de la largeur au niveau de l'ouverture d'évacuation. L'engrenage intermédiaire est un engrenage étagé dans lequel un premier engrenage venant en prise avec l'engrenage de sortie et un second engrenage plus grand en diamètre que le premier engrenage sont agencés en parallèle. Le second engrenage est agencé dans une position différente de celle de l'engrenage de sortie dans le sens de la largeur.
