Title (EN) INK JET PRINTER
(FR) IMPRIMANTE A JET D'ENCRE
Abstract:
(EN) A planetary gear mechanism is assembled into a pump unit frame with an ink supply pump, a buffer purge pump, a suction pump, a motor shaft gear, and a wiper member. The buffer purge pump and the suction pump are configured to be selectively driven by switching rotational direction of a motor having the motor shaft gear. The planetary gear mechanism transmits drive force from the motor shaft gear to the buffer purge pump or the suction pump in accordance with rotational direction. The buffer purge pump and the wiper member are selectively driven by the rotations of the motor rotating in the same direction in phase-dependent on the rotations of the motor.
(FR) L'invention concerne un mécanisme de roue planétaire assemblé dans un cadre pour unité de pompes comprenant une pompe à alimentation en encre, une pompe de purge tampon, une pompe d'aspiration, une roue d'arbre de moteur et un élément essuyeur. La pompe de purge tampon et la pompe d'aspiration sont configurées pour être entraînées de manière sélective par un changement de sens de rotation d'un moteur comportant cette roue d'arbre de moteur. Ce mécanisme de roue planétaire transmet une force d'entraînement de la roue d'arbre de moteur à la pompe de purge tampon ou à la pompe d'aspiration, selon le sens de rotation. La pompe de purge tampon et l'élément essuyeur sont entraînés de manière sélective par les rotations du moteur tournant dans le même sens, leurs phases dépendant des rotations du moteur.
