<p>PROBLEM TO BE SOLVED: To prevent the air from entering a liquid housing part of a pump means at a low cost when taking out a vacant liquid reservoir part.SOLUTION: An ink supply device includes a diaphragm pump which sucks ink (liquid), which is in an ink cartridge (liquid reservoir part), into a liquid housing part by reducing volume of a diaphragm (liquid housing part) and supplies the liquid in the liquid housing part to a liquid supply destination such as a head tank by increasing the volume of the liquid housing part. It includes a shielding member 310 which is interlocked with the action of an opening/closing cover from a closed state to an opened state of a device case in which the liquid supply device is housed, so that an inlet side flow path 221 which connects the liquid reservoir part to the liquid housing part becomes a shielded state.</p> |
