Abstract:
1. A liquid supply device comprising: a plurality of liquid holding parts each holding liquid, formed of an elastically deformable material, and adapted to be increased in a volume of the liquid holding part by an outward actuation force of a spring provided in the liquid holding part; a plurality of regulation units each adapted to regulate an increase in a volume of a corresponding one of the plurality of liquid holding parts; a movement unit adapted to move the plurality of regulation units to a position where the increase in the volume of at least one of the plurality of liquid holding parts is regulated by the plurality of regulation units; a rotating shaft adapted to be rotated in one of first and second directions; and a plurality of drive transmission units disposed on a peripheral surface of the rotating shaft in positions corresponding to the plurality of regulation units, wherein the movement unit is adapted to: move the plurality of drive transmission units when the rotating shaft is rotated in the first direction so that adjoining ones of the plurality of drive transmission units are arranged to have a phase difference around the rotating shaft when viewed from an axial direction of the rotating shaft, wherein one of the plurality of drive transmission units selectively causes a corresponding one of the plurality of regulation units to regulate the increase in the volume of a corresponding one of the plurality of liquid holding parts; and move the plurality of drive transmission units when the rotating shaft is rotated in the second direction so that the plurality of drive transmission units are arranged in phase with one another when viewed from the axial direction of the rotating shaft, wherein the plurality of drive transmission units simultaneously cause all the plurality of regulation units to regulate the increase in the volume of each of the plurality of liquid holding parts.
