Liquid supply device and image forming apparatus
A liquid supply device includes diaphragms, pressing members, a movement unit, a rotating shaft, and cams. In the liquid supply device, when the rotating shaft is rotated in a first direction, the cams are moved to arrange adjoining ones of the cams to have a phase difference around the rotating shaft, in which one of the cams selectively causes a corresponding one of the pressing members to regulate an increase in a volume of a corresponding one of the diaphragms. When the rotating shaft is rotated in a second direction, the cams are moved to arrange the cams in phase with one another when viewed from an axial direction of the rotating shaft, in which the cams simultaneously cause all the pressing members to regulate the increase in the volume of each of the diaphragms.
