A printing-fluid cartridge is inserted into a printing-fluid consuming apparatus in an insertion direction crossing a gravitational direction and attached thereto in a first posture. The printing-fluid cartridge includes: a storage chamber, a supply portion having a supply port, an upper surface and a locking surface positioned upward of the storage chamber, an electrical interface disposed at the upper surface, and a contact surface positioned rearward relative to the supply port of the supply portion in the insertion direction in the first posture. 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.

Examples of electrical connectors are provided herein. In some examples, an electrical connector includes a contact pad at a first end of a route. In some examples, the electrical connector includes a bond at a second end of the route. In some examples, the contact pad and the bond include a copper layer on a substrate, a nickel layer on the copper layer, and a gold layer on the nickel layer. In some examples, the gold layer has a first thickness on the contact pad and has a second thickness on the bond. In some examples, the second thickness is greater than the first thickness.

A communication system may include a printer and a terminal device. The printer may, in a case where a predetermined operation is accepted, execute a communication process and, in a case where sending of start information to a server fails in the communication process, execute an output process for causing an output unit to output communication information for communicating with the server and start related information obtained by using the start information. The terminal device may obtain the communication information and the start related information outputted by the printer and, in a case where the communication information and the start related information are obtained, send the start related information to the server using the communication information.

A recording apparatus 101 includes a carriage 21 mounted with a liquid storage portion 46 and a recording head 22, the carriage 21 being movable to a visual check position, where liquid in the liquid storage portion 46 is visually checkable through a front surface 43F, and to a recording position, where the recording head 22 ejects the liquid to a medium, and light emitting units 81 and capable of illuminating the inside of the liquid storage portion 46 at least when the carriage 21 is positioned at the visual check position.

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.

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.

An inkjet printer includes a support member configured to support a recording medium moving in a first direction, a carriage configured to reciprocate in a second direction orthogonal to the first direction and provided with a first electrical contact and a second electrical contact, a first recording head mounted on the carriage so as to contact the first electrical contact and configured to reciprocate together with the carriage, and an electrical contact protection member mounted on the carriage so as to contact the second electrical contact and configured to reciprocate together with the carriage. A shortest distance between the electrical contact protection member mounted on the carriage and the support member in a third direction is greater than a shortest distance between the first recording head mounted on the carriage and the support member in the third direction, the third direction being orthogonal to the first and second directions.

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.
