Abstract:
1. A liquid containing chamber configured to be mounted to a liquid ejecting apparatus in a vertical direction and to supply liquid to the liquid ejecting apparatus, the liquid containing chamber comprising: a liquid supply unit that supplies the liquid to the liquid ejecting apparatus; a first liquid container of containing the liquid and coupled with the liquid supply unit by a fluid path, the first liquid container having a maximum length in a first direction which is longer than a maximum length in a second direction perpendicular to the first direction, the first direction being the vertical direction when the liquid containing chamber is mounted on the liquid ejecting apparatus and the liquid supply unit is located at a vertically lower position than the first liquid container; a first projection provided in the first liquid container; and a first stirring member provided in the first liquid container and supported by the first projection so as to be rotatable within a predetermined range of angles to stir the liquid in the first liquid container, the first stirring member comprising a plate extending from the supported position toward a portion of the first liquid container, the portion being a bottom when the liquid containing chamber is mounted on the liquid ejecting apparatus, wherein the first stirring member is rotatable around the first projection by the acceleration of the liquid containing chamber, wherein the first liquid container is divided into a first container portion and a second container portion, the first container portion is an upper container portion located vertically above the first projection and contains the liquid and an amount of air when the liquid containing chamber is mounted on the liquid ejecting apparatus, the air is configured to stir the liquid in the upper container portion, and the second container portion is a lower container portion located vertically below the upper container portion and contains the liquid when the liquid containing chamber is mounted on the liquid ejecting apparatus, a second liquid container coupled with the first liquid container and the liquid supply unit, the second liquid container positioned between the first liquid container and the liquid supply unit, the second liquid container having a horizontally long shape in a mounted position; a second projection provided in the second liquid container; and a second stirring member supported by the second projection so as to be rotatable within a predetermined range of angles, the second stirring member comprising a plate extending from the supported position toward a bottom of the second liquid container in the mounted position, wherein the first liquid container has an air communication hole for communicating with air, wherein the second stirring member is rotatable around the second projection by the acceleration of the liquid containing chamber, and wherein in an initial state, the second liquid container contains the liquid, and the second stirring member stirs the liquid contained in the second liquid container by rotation of the second stirring member.
