  • Patent number: 9365042
    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.

  • Publication number: 20150352850
    Abstract: A tank unit includes two or more liquid accommodating containers disposed in a row. Each of the liquid accommodating containers includes a main body having a concave shape defining a side opening and a film that blocks the side opening. The main body and the film at least partially define a liquid accommodating chamber for accommodating a liquid. The main body includes a facing wall that faces the film across the liquid accommodating chamber and has a wall larger than the side opening. The liquid accommodating containers are disposed such that the film of at least one of the liquid accommodating containers is covered by the facing wall of an adjacent one of the liquid accommodating containers.

  • Patent number: 9061509
    Abstract: A liquid holding container includes a holding body case, a film and a reinforcing member. The holding body case has a case opening section. The film adheres to the holding body case to cover the case opening section and form a liquid holding chamber configured and arranged to accommodate liquid between the holding body case. The reinforcing member is provided along a surface of the film at a position which is on an opposite side to the liquid holding chamber with respect to the film so as to suppress deformation of the film toward the opposite side.
