Abstract

A liquid cartridge and a liquid-consuming device are provided. The liquid cartridge includes: a front surface facing frontward, a rear surface spaced apart from the front surface, an upper surface facing upward and is disposed between the front surface and the rear surface, a liquid supply portion provided at the front surface, a detection portion, an electrical interface disposed at the upper surface, and an engaging surface. The detection portion includes a light-receiving portion configured to receive incident light thereon. The light-receiving portion is positioned upward relative to the upper surface and configured to change a state of the light depending on a state of the liquid cartridge. The engaging surface faces rearward and configured to be engaged with an external member such that the engagement between the engaging surface and the external member restricts the liquid cartridge from moving rearward. The electrical interface and the engaging surface are positioned frontwardrelative to the light-receiving portion.

Description

technical field [0001] The present disclosure relates to a liquid cartridge storing liquid therein and a liquid consuming device to which the liquid cartridge can be attached. The present disclosure also relates to a system consisting of a fluid cartridge and a fluid consuming device. Background technique [0002] Conventionally, there is known an inkjet recording apparatus configured to print an image on a recording medium by ejecting ink stored in an ink cartridge through nozzles. Whenever ink stored in an ink cartridge is used up, a new ink cartridge is detachably mounted in such a jet recording apparatus. [0003] For example, Japanese Patent Application Laid-Open No. 2002-508720 discloses an ink tank that can be attached to and detached from a printer. During attachment of the ink container to the printer, the ink container's liquid outlet and air inlet are configured to fit into the printer's liquid inlet and air outlet, respectively, such that the ink container is p...
