  • Patent number: 11364723
    Abstract: A liquid cartridge includes: a housing including first and second protrusions; and a circuit board including an electrode. The first protrusion is positioned rearward but the second protrusion is positioned forward relative to the circuit board. When viewed in a width direction crossing a gravitational direction, an outline of the liquid cartridge between a first point and a second point is lower than an imaginary line. The imaginary line passes through the first point on the first protrusion and the second point on the second protrusion. A distance between a front edge of the electrode and the first point is smaller than a distance between the front edge and the second point. A dimension between a front end and a rear end of the second protrusion is greater than a distance between a frontmost end of the housing and the front end of the second protrusion.

In the connection mechanism for the liquid flow path, in a case of disconnecting the container from the apparatus main body, a second biasing member biases the slide portion to connect the air flow path to the liquid flow path, and the first main body portion is separated from the slide portion, so that a first biasing member biases the first open/close valve to close a part of the liquid flow path included in the first main body portion.
