Claim:
A liquid cartridge comprising: a liquid reservoir configured to store liquid therein; a liquid flow path configured to selectively allow the liquid reservoir to be in fluid communication with an exterior of the liquid cartridge; a sensor configured to output a signal relative to a position of an object other than the liquid disposed in the liquid flow path; a storage configured to store data therein; a plurality of terminals, wherein the plurality of terminals comprises: a sensor terminal connected to the sensor; a power terminal connected to at least one of the sensor and the storage, and configured to receive power from an exterior of the cartridge; and a data terminal connected to the storage, wherein a distance between at least a first portion of the power terminal and at least a portion of the data terminal is greater than a distance between at least a second portion of the power terminal and at least a portion of the sensor terminal; and a substrate, wherein the plurality of terminals is disposed on the substrate, wherein the substrate is divided into a rectangular grid along a particular direction and a further direction perpendicular to the particular direction, and wherein each of the plurality of terminals is disposed such that a center portion is positioned within a cell of the rectangular grid, and a cell containing the center portion of the power terminal is aligned with and adjacent to a cell containing the sensor portion in the particular direction, and the cell containing the center portion of the power terminal is not aligned with a cell containing the center portion of the data terminal in either the particular direction or the further direction.
