Abstract

L'invention porte sur un appareil de génération d'image qui permet de remplacer facilement une cartouche de traitement et qui est donc plus pratique. L'appareil de génération d'image comporte un plateau de cartouches qui peut se déplacer dans une direction pour le corps principal de l'imprimante tout en contenant les cartouches de traitement de façon à ce qu'elles soient agencées de façon amovible en parallèle dans la première direction, et un mécanisme de verrouillage (cavité, rouleau) pour verrouiller le plateau de cartouches sur le corps principal de l'imprimante dans un état dans lequel le plateau de cartouches est déplacé à partir du corps principal de l'imprimante. Au moins une position de verrouillage dans laquelle le plateau de cartouches doit être verrouillé au corps principal de l'imprimante par le mécanisme de verrouillage est prévue entre une position dans laquelle le plateau de cartouches est fixé au corps principal de l'imprimante et une position dans laquelle le plateau de cartouches est sorti au maximum du corps principal de l'imprimante.
