Abstract:
1. A liquid cartridge comprising: a housing having a space therein; a liquid storing section provided in the housing and configured to store liquid; a channel member provided in the housing and formed with a liquid channel having one end and another end, the one end being in fluid communication with the liquid storing section, the another end being in fluid communication with outside to serve as a discharge port for discharging liquid to the outside; a movable member that is movable in the liquid channel; a sensor configured to generate a signal based on a position of the movable member in the liquid channel; a sensor-signal output terminal connected electrically with the sensor and configured to output the signal to the outside; and a wiring line that connects the sensor with the sensor-signal output terminal, wherein the housing comprises: wherein the sensor-signal output terminal is disposed on the first outer surface; wherein the discharge port is disposed on the second outer surface; wherein the channel member is disposed at a position closer to the second outer surface than the liquid storing section is; wherein the liquid storing section is disposed at a position closer to the third outer surface than the channel member is; wherein a first direction is defined as a direction perpendicular to the first outer surface, a second direction is defined as a direction perpendicular to the second outer surface, and a third direction is defined as a direction perpendicular to both the first direction and the second direction; wherein, when the space in the housing is divided by an imaginary line parallel to the first direction, as viewed from the third direction, into a first region in which the channel member is disposed and a second region in which the liquid storing section is disposed, the sensor and the sensor-signal output terminal are disposed in the first region; wherein the liquid channel extends linearly in the second direction; and wherein the sensor and the sensor-signal output terminal are arranged to be aligned in the first direction.
