Abstract: A first ink tank, and a second ink tank including a first chamber having an ink inlet port and a second chamber having a sensing unit are provided. The ink inlet port is provided at a position so that a volume of the second ink tank above a second height does not become smaller than an amount of ink volume change in the second chamber when the ink volume is changed from a first height which is a height of the ink surface when a minimum volume of ink is in the second ink tank under normal usage to a second height which is a height of the ink inlet port.

Abstract: The present invention provides an inkjet printing apparatus capable of achieving thorough stirring by producing a flow in a main tank and a sub tank. The inkjet printing apparatus includes a printing head, a main tank, and a sub tank. The apparatus includes an ink reservoir unit formed of a flexible member, disposed between the sub tank and the printing head. The ink is supplied from the sub tank to the printing head by increasing the volume of the ink reservoir unit, and air in the sub tank is sent to the main tank by reducing the volume of the ink reservoir unit.

Abstract: Provided is a liquid holding container in which waste liquid leakage is not caused even when the container is turned upside down. For this purpose, a surface of an absorber facing the rear face of a cover part is disposed apart from the cover part so as to form a space between the cover part and the absorber of a waste liquid holding container.

Abstract: A supply apparatus includes a holder for a liquid container, a link coupled to the holder, an operation handle rotatably coupled to the link, an engaging portion and a rotation restriction unit. The operation handle operate connection and disconnection of the liquid container to and from a supplying portion by rotation with respect to the link. The engaging portion maintains a connection state between the supplying portion and the liquid container by engaging with the operation handle. The unit can restrict rotation of the operation handle when the engaging portion and the operation handle are in a disengaged state.
