<p>PROBLEM TO BE SOLVED: To prevent attraction of air into liquid holding parts by simultaneously regulating the increase in the volume of each of a plurality of liquid holding parts.SOLUTION: In a liquid supply device, when a rotating shaft 191 is rotated in one direction, a plurality of cams 208 as drive transmission means are moved to positions having different phases around the shaft with one another when viewed from an axial direction of the rotating shaft 191, whereby one of the plurality of cams 208 selectively moves corresponding one of a plurality of pressing members 206 to positions to regulate the increase in the volume of corresponding one of a plurality of diaphragms 203a. When the rotating shaft 191 is rotated in the other direction, the plurality of cams 208 are moved to positions to be arranged almost in parallel with one another in the axial direction when viewed from the axial direction of the rotating shaft 191, whereby all of the plurality of cams 208 move all of the plurality of pressing members 206 to positions to regulate the increase in the volume of each of the plurality of diaphragms 203a.</p> |
