  • Liquid detection system, liquid container, mounting member, and liquid supply system
    Patent number: 8801126
    Abstract: A liquid chamber receives liquid flows from a liquid receiving unit. A first urging member urges a deforming portion of the liquid chamber. A lever provided on the liquid container side increases the displacement of the deforming portion. A sensor detects the displacement. A transmitting member transmits the increased displacement to the sensor. A second urging member provided on a liquid consuming apparatus side urges the transmitting member. When the liquid container is installed in the liquid consuming apparatus, the transmitting member comes in contact with the lever member due to the urging force of the second urging member, and the lever member is pushed against the deforming portion. In this manner, it is possible to divide the liquid detection system into the liquid consuming apparatus side and the liquid container side.
