The plug member is retained to the operating member by a retaining member and configured to plug the liquid introducing portion at the first position. The covering portion is configured to cover the plug member in a direction intersecting with the first direction.

Liquid discharge apparatus having liquid container and operating member

A liquid ejection apparatus includes a first liquid storage container, a second liquid storage container, a first terminal member, a second terminal member, and a circuit board. The first liquid storage container stores liquid to be supplied to a liquid ejection head that ejects the liquid to an ejection medium. The second liquid storage container is arranged side by side in a first direction with respect to the first liquid storage container. The first terminal member comes into contact with the liquid stored within the first liquid storage container. The second terminal member comes into contact with liquid stored within the second liquid storage container. The circuit board comes into contact with the first terminal member and the second terminal member and relatively moves in the first direction with respect to the first liquid storage container.

Liquid ejection apparatus

A liquid discharge apparatus includes a liquid discharge head to discharge liquid to a medium and a liquid storage container. The liquid storage container includes a reservoir portion, a liquid injection portion, a liquid holding unit, and a liquid guide portion. The reservoir portion reserves the liquid that is supplied to the liquid discharge head. The liquid injection portion allows a liquid injection container for injecting the liquid into the reservoir portion to be inserted in the liquid injection portion in a first direction. The liquid holding unit is provided at a position spaced apart from the liquid injection portion and is capable of holding the liquid. The liquid guide portion guides the liquid from the liquid injection portion to the liquid holding unit in a second direction intersecting with the first direction.

Liquid discharge apparatus and liquid storage container

A liquid discharge apparatus includes a tube configured to connect a liquid discharge unit and a liquid container, a protective member configured to protect the tube, and a holder configured to hold the protective member. The holder holds the protective member by a first projection of the holder being inserted into a first opening in the protective member, such that a portion of the first projection protrudes from the first opening, and, in a state where the protective member is attached to the holder, a length of the portion of the first projection in a first direction in which a short side of the first opening extends is greater than that of the first opening in the first direction, and the length of the portion of the first projection in the first direction is less than that of the first opening, in the second direction crossing to the first direction.

A power transmission apparatus includes a first pulley and a second pulley. A belt is extended around them. A supply unit supplies a voltage such that the first pulley and the belt are electrostatically attracted and that the second pulley and the belt are electrostatically attracted. The belt includes a conductor layer. At least one pulley includes a first electrode to which a first voltage is applied and a second electrode that is insulated from the first electrode and to which a second voltage is applied. An insulating layer or a dielectric layer is arranged between the conductor layer of the belt and the first electrode of the at least one pulley and an insulating layer or a dielectric layer is arranged between the conductor layer of the belt and the second electrode of the at least one pulley.
