Abstract: A printing liquid container fits to one of first and second tanks each including a fitted portion. The printing liquid container includes a first member having a supply port, and a second member having a valve configured to open or close the supply port. The first member and the second member are rotatable with respect to each other between a first state and a second state. The valve closes the supply port in the first state and opens the supply port in the second state. The first member has a fitting portion configured to fit to the fitted portion. The second member is rotatable with respect to the fitted portion when at least a portion of the second member is inserted into the fitted portion. The first member does not rotate by the rotation of the second member due to the fitting between the fitted portion and the fitting portion.

Abstract: A liquid cartridge includes a case, a liquid supply portion, a circuit board, a residual-amount detecting portion, a base surface, and a plate member. The residual-amount detecting portion includes an optical access portion accessible by light traveling in a left-right direction. The optical access portion has a portion positioned above and away from electrodes of the circuit board by a first distance in an attached posture. The plate member extends frontward from the base surface, and provides a light-shielding region and a light-transmissive region. The light-shielding region is positioned rearward of the electrodes and frontward of the residual-amount detecting portion. The light-transmissive region is positioned rearward of the light-shielding region and frontward of the residual-amount detecting portion. Each of the light-transmissive region and the light-transmissive region has a portion positioned above and away from the electrodes by the first distance in the attached posture.

Abstract: A tank includes: a tank body defining a storage chamber; a recessed portion provided at the tank body; a slider positioned in the recessed portion; a fitting portion provided at the slider; and a sealing member. The recessed portion has an injection opening in communication with the storage chamber, and a connection opening through which a liquid container is connectable. The slider includes a nozzle extending toward the connection opening in an extending direction and having a communication opening communicable with the injection opening. The slider is movable toward and away from the connection opening in the extending direction while rotating relative to the recessed portion. The fitting portion can be fitted with the liquid container. The sealing member can provide a liquid tight sealing to a gap between the slider and the recessed portion, and allow liquid flow between the communication opening and the injection opening.

Abstract: An ink injection cylinder includes a first flow path tube and a second flow path tube extending in a longitudinal direction. The first flow path tube has a first opening on one side in the longitudinal direction, a second opening on another side in the longitudinal direction, and a first flow path formed between the first and second openings. The second flow path tube has a third opening on the one side in the longitudinal direction, a fourth opening on the other side in the longitudinal direction, and a second flow path formed between the third and fourth openings. At least one of a first virtual plane including at least a portion of an end surface of the second opening and a second virtual plane including at least a portion of an end surface of the fourth opening intersects with a plane orthogonal to the longitudinal direction.

Abstract: A liquid cartridge includes: a casing including a liquid chamber; a liquid supply portion; a deformable member; a movable member; and a support member. The liquid chamber is configured such that an internal pressure of the liquid chamber is reduced as liquid flows out of the liquid chamber. The liquid supply portion allows liquid in the liquid chamber to flow out of the liquid chamber. The deformable member protrudes further upward relative to an upper surface of the casing. The deformable member has an internal space in communication with the liquid chamber. The deformable member is elastically deformable such that a volume of the internal space is reduced as the internal pressure of the liquid chamber is reduced. The movable member includes a detection portion movable in upward and downward directions in accordance with the elastic deformation of the deformable member. The support member supports the movable member.
