The printing-fluid cartridge inserted in the printing-fluid consuming apparatus is movable between the first posture and a second posture. In the first posture, the locking surface engages a lock portion and the contact surface abuts against a positioning portion. In the second posture, the locking surface is positioned downward relative to the lock portion and the contact surface is separated from the positioning portion.

A liquid ejecting apparatus includes a liquid ejecting head that ejects liquid and an attachment portion to which a liquid container that stores the liquid supplied to the liquid ejecting head is detachably attached. The attachment portion includes a liquid inlet portion that is coupled to a liquid outlet provided in the liquid container, and an urging mechanism that urges the liquid container in a direction opposite to an attaching direction in which the liquid container is attached to the attachment portion. The urging mechanism includes an elastic member that is in close contact with the liquid container attached to the attachment portion and that is provided below the liquid inlet portion in a direction of gravity.

A liquid replenishing container configured to replenish recording liquid to a liquid storage container having a receiving portion of the recording liquid, includes a holding portion that holds recording liquid to be replenished to the liquid storage container; and an injecting portion that has an opening to discharge the recording liquid in the holding portion, and that is inserted into the receiving portion of the liquid storage container, wherein the opening opens so as to face an inner wall of the receiving portion.

A mobile device configured to be coupled to a counterpart device includes a driving section configured to be driven by electric power, a coupling section configured to be coupled to the counterpart device, and an accommodation section configured to accommodate an all-solid-state battery. When the counterpart device is coupled to the coupling section, the driving section is driven by electric power supplied from the counterpart device, and when the counterpart device is not coupled to the coupling section, the driving section is driven by electric power supplied from the all-solid-state battery.

An inkjet printing apparatus includes a print head ejecting ink, a tank reserving ink to be supplied to the print head and a joint unit being capable of connecting the print head and the tank to each other. The joint unit has a connecting portion for supplying ink to the print head and a shaft that is rotatable by a drive source so as to move in an axial direction. The connecting portion moves together with the shaft. The print head includes a head joint connectable to the connecting portion and an engaging portion engageable with one end of the shaft. The shaft is rotated to be engaged with the engaging portion so that the head joint and the connecting portion are connected to each other.

In one example in accordance with the present disclosure, a printing fluid container for a printing system is described. The printing fluid container includes a container body for holding printing fluid, a collar connected to the container body, and a cap removably engaging the collar. The collar has a plurality of collar teeth extending peripherally around the collar. The cap has a plurality of cap teeth extending peripherally around the cap. The cap teeth are configured for interfitment with the collar teeth such that rotation of the cap about the longitudinal axis in a first rotational direction effects cam-actuated removal of the cap from the collar.

Provided is a discharged liquid container detachable to an apparatus having an outlet portion from which discharged liquid is to be drained, and configured to contain the discharged liquid drained from the outlet portion. The discharged liquid container includes a casing inside which the discharged liquid is containable, a connection portion provided in a first face of the casing and configured to be coupled to the outlet portion, and a lid portion configured to change in position between a closed state for covering the connection portion and an open state for opening the connection portion. The lid portion is configured to be in the open state in a state of attachment of the casing to the apparatus and be in the closed state in a state of detachment of the casing from the apparatus.

A supply unit in which a liquid container including a coupling portion being detachably mounted includes: a liquid introduction unit coupled to the coupling portion of the liquid container; an urging member that urges the liquid container in an uncoupling direction which is a direction opposite to a coupling direction, the coupling direction being a direction in which the liquid container is coupled to the liquid introduction unit; and an engagement lever having an engaging portion that engages with the liquid container when the liquid container is coupled to the liquid introduction unit, the engagement lever includes an operating portion operated by a user and a pressing portion configured to press the liquid container and is configured to release the engagement of the engaging portion with the liquid container when the operating portion is operated and to press the liquid container in the uncoupling direction by the pressing portion.

The object is to provide a liquid container capable of supplying liquid to a liquid ejection apparatus with simple configuration. Liquid container 100 has liquid containing bag 120 and an introduction member. The introduction member includes the first and second liquid introduction members. The first introduction member has the first spacer unit and the first coupling unit integrally connected to the first spacer unit in which the first groove for letting liquid flow to a liquid lead-out unit is formed. The second introduction member has the second spacer unit and the second coupling unit integrally connected to the second spacer unit in which the second groove for letting liquid flow to the liquid lead-out unit is formed. The first and second liquid introduction members are adjoined so that the surface on which the first groove is formed and the surface on which the second groove is formed face each other.

A recording apparatus includes an ink tank, a recording head, a carriage, an ink supply channel, one or more memory devices, and one or more processors to execute the set of instructions to perform operations including causing the recording head to eject the ink based on print data to perform recording on a recording medium; and obtaining, based on the print data, information on an amount of ink to be ejected to a recordable area in which the carriage moves in one of the first direction and the second direction. A length of the ink supply channel from the bend to the recording head increases in the first direction and decreases in the second direction. The one or more processors changes acceleration of the carriage according to the amount of ink to be ejected to the recordable area, the amount being indicated by the information.
