Liquid container and liquid ejecting system

A liquid ejecting system comprising:

• a liquid ejecting apparatus which ejects a liquid, and
• a liquid container which is mounted on the liquid ejecting apparatus to supply the liquid to the liquid ejecting apparatus,
• the liquid container including
• a storage unit which stores the liquid;
• an optical member having one portion which is exposed to an inside of the storage unit, and the other portion which is exposed to an outside of the liquid container;
• and
• a reflection portion which is provided at the same side as the other portion of the optical member on the outside of the liquid container, and is installed in front of a mounting direction of the liquid container to the liquid ejecting apparatus with respect to the other portion of the optical member,
• the liquid ejecting apparatus including
• an optical sensor which emits light toward a position which should be occupied by the optical member of the liquid container mounted on the liquid ejecting apparatus, and receives reflected light emitted from the position;
• a display unit which performs a desired display for a user;
• and
• a control unit which performs a first display indicating a small residual amount of the liquid on the display unit in a case where a first condition including a fact that the optical sensor receives the reflected light of a predetermined amount or more is satisfied when the liquid is ejected, and which performs a second display different from the first display on the display unit in a case where a second condition including a fact that the optical sensor does not receive the reflected light of a predetermined amount or more is satisfied when the liquid is ejected, or does not perform the display on the display unit,
• wherein the control unit performs a third display indicating that mounting of the liquid container is insufficient in a case where a third condition including a fact that the optical sensor receives the reflected light of the predetermined amount or more is satisfied when the liquid container is mounted on the liquid ejecting apparatus, and performs a fourth display different from the third display on the display unit in a case where a fourth condition including a fact that the optical sensor does not receive the reflected light of the predetermined amount or more is satisfied when the liquid container is mounted on the liquid ejecting apparatus, or does not perform the display on the display unit.
