Liquid detection system, liquid container, mounting member, and liquid supply system

A liquid container which is detachably mounted with respect to a liquid consuming apparatus, comprising:

• a liquid receiving unit which can receive liquid which is consumed in the liquid consuming apparatus;
• a liquid chamber into which liquid flows from the liquid receiving unit, and has a deforming portion which can deform at a part thereof;
• a first urging member which causes an urging force to be applied to the deforming portion, which is opposite to the deformation of the deforming portion due to a negative change in pressure of the liquid chamber which accompanies a supply of liquid to the liquid consuming apparatus;
• and
• a lever member which is rotatably provided about a fulcrum,
• wherein the lever member comes in contact with a transmitting member which is provided in the liquid consuming apparatus, and of which a displacement can be detected using a sensor which is provided in the liquid consuming apparatus, and has a second contact point in which a displacement of the deforming portion which comes in contact with a first contact point of the lever member is increased at a predetermined lever ratio, when being installed in the liquid consuming apparatus.

A mounting member which is detachably mounted with respect to the liquid consuming apparatus, comprising:

• a liquid chamber into which liquid flows from outside, and has a deforming portion which can deform at a part thereof;
• a first urging member which causes an urging force to be applied to the deforming portion, which is opposite to the deformation of the deforming portion due to a negative change in pressure of the liquid chamber which accompanies a supply of the liquid to the liquid consuming apparatus;
• and
• a lever member which is rotatably provided about a fulcrum, increases a displacement of the deforming portion which comes in contact with a first contact point at a predetermined lever ratio, and transmits the displacement to a second contact point,
• wherein the lever member comes in contact with a transmitting member which is provided in the liquid consuming apparatus, and of which a displacement can be detected using a sensor which is provided in the liquid consuming apparatus, and has a second contact point in which a displacement of the deforming portion which comes in contact with the first contact point of the lever member is increased at a predetermined lever ratio, when being installed in the liquid consuming apparatus.
