Abstract

A liquid supply device 10 is equipped with a liquid containing chamber 16, a transport tube 15 for sending the liquid inside the chamber 16 to a liquid jetting device 20, first and second members 171 and 172 sandwiching the tube 15, and a cam 173 that determines the position of the first member 171 relative to the second member 172. The tube 15 is equipped with an elastic portion 151 that elastically deforms and is flattened. In the first rotation position, the cam 173 arranges the first member 171 such that there is a space that allows the liquid to flow inside the part 151 between the first and second members 171, 172. In the second rotation position, the cam 173 arranges the first member 171 such that the elastic portion 151 is flattened by the first and second members 171, 172, and the liquid inside cannot flow.

Claims9

Dependent claims

A liquid supply device for supplying liquid to a liquid jetting device, the liquid supply device comprising:

a liquid containing chamber that contains liquid;
a tube for sending the liquid in the liquid containing chamber to the liquid jetting device, the tube including at least in part an elastic portion that can elastically deform and be flattened;
and
first and second members arranged sandwiching the elastic portion of the tube, wherein
the first member is configured to be arranged at:
a first relative position relative to the second member, wherein there is a space between the second member and the first member at the first relative position, the space allowing the liquid to flow inside the elastic portion;
and
a second relative position relative to the second member that is closer to the second member than the first relative position, wherein the elastic portion is sandwiched and flattened by the second member and the first member at the second relative position, and the liquid cannot flow inside the elastic portion.
