First Claim
1. A liquid cartridge comprising:
- a liquid storing portion configured to store liquid therein;
a liquid path configured to be in fluid communication with the liquid storing portion;
a sensor configured to output a particular data corresponding to a particular value indicating that the liquid storing portion is in fluid communication with an exterior of the liquid cartridge, and a further data corresponding to a further value indicating that the liquid storing portion is not in fluid communication with the exterior of the liquid cartridge; and
a memory comprising a first data corresponding to a first value and a second data corresponding to a second value, wherein the first value and the second value are defined such that when the particular data and the further data are outputted, one half of a sum of the first value and the second value is between the particular value and the further value.

Abstract
A liquid cartridge includes a liquid storing portion that stores liquid therein, a liquid path that is in fluid communication with the liquid storing portion, a sensor, and a memory. The sensor outputs a particular data corresponding to a particular value indicating that the liquid storing portion is in fluid communication with an exterior of the liquid cartridge, and a further data corresponding to a further value indicating that the liquid storing portion is not in fluid communication with the exterior of the liquid cartridge. The memory includes a first data corresponding to a first value and a second data corresponding to a second value. The first value and the second value are defined such that when the particular data and the further data are outputted, one half of a sum of the first value and the second value is between the particular value and the further value.
