摘要： A liquid cartridge configured to be inserted into a cartridge-attachment section in an insertion direction includes a casing, and a lever supported by the casing. The lever is pivotable about a pivot axis between a first position and a second position. The lever includes a light-blocking portion configured to block or attenuate light traveling in a widthwise direction crossing the insertion direction and a gravitational direction, and a force-receiving portion positioned closer to a front wall of the casing than the light-blocking portion is to the front wall in the insertion direction. The light-blocking portion is positioned lower at the second position than at the first position. The pivot axis is positioned frontward of the light-blocking portion and rearward of the force-receiving portion in the insertion direction. The lever pivots from the second position to the first position upon application of an external force to the force-receiving portion.

摘要： A liquid cartridge includes: a cartridge casing having a liquid storage chamber; a first wall; a second wall; and an air communication passage. The first wall is positioned upward relative to the liquid storage chamber. The second wall is positioned upward relative to the first wall. The air communication passage has a first communication hole in communication with the liquid storage chamber and a communication opening open to an atmosphere. The air communication passage includes: an air chamber defined by the first wall and the second wall and in communication with the liquid storage chamber through the first communication hole; a second communication hole formed in the second wall; and a labyrinth path. The labyrinth path is positioned upward relative to the air chamber, and has one end in communication with the second communication hole and another end in communication with the communication opening.

摘要： A liquid jetting apparatus includes: a head which jets liquid supplied from a liquid tank; a memory which stores pieces of reference data; and a controller which estimates viscosity of the liquid in the liquid tank every time a predefined time passes. The controller acquires a total supply amount or cumulative supply amount of the liquid supplied from the liquid tank and a supply amount of the liquid per unit time within the predefined time, estimates a viscosity change amount of the liquid in the liquid tank based on the cumulative supply amount acquired, the supply amount per unit time acquired, and the pieces of reference data, and estimates the viscosity of the liquid in the liquid tank based on the viscosity change amount estimated and the viscosity of the liquid in the liquid tank at an initial timing point or a most-recent estimation timing point.

摘要： A printing fluid cartridge a printing fluid cartridge is configured to be inserted into a printing fluid consuming apparatus in an insertion direction. The printing fluid cartridge includes: a storage chamber, a supply portion, a rear surface, an upper surface, an electrical interface, a locking surface, one protrusion, and another protrusion. The storage chamber is configured to store printing fluid. The one protrusion and the another protrusion define a plurality of imaginary planes each of which passes through the one protrusion and the another protrusion. The plurality of imaginary planes includes a specific imaginary plane. The specific imaginary plane is positioned higher than any other imaginary plane between the one protrusion and the another protrusion. The electrical interface is positioned downward relative to the specific imaginary plane in the gravitational direction in the attached posture.

摘要： A printing-fluid cartridge is inserted into a prescribed insertion space of a cartridge-attachment section in an insertion direction crossing a gravitational direction to be attached thereto in an attached posture. The printing-fluid cartridge includes: a housing including a storage chamber, a supply portion having a supply hole, an electrical interface disposed at an upper surface of the housing, and an interfering surface. The interfering surface is positioned upward of the storage chamber and extends in a widthwise direction of the housing. The interfering surface is positioned downward and frontward relative to the electrical interface and is configured to abut against a projection provided at another insertion space different from the prescribed insertion space of the cartridge-attachment section during an insertion of the printing-fluid cartridge into the another insertion space.
