A liquid cartridge includes a first surface, a second surface spaced apart from the first surface, and a third surface extending between the first surface and the second surface, with a liquid outlet through the first surface. A circuit board is mounted on the third surface. A locking mechanism includes a locking surface that extends above the third surface, and a liquid detection mechanism includes a light access portion. The light access portion is disposed between the circuit board and the locking surface, and the circuit board is disposed between the first surface and the light access portion.

Liquid cartridge

A liquid jetting apparatus includes: a casing; a tank configured to store liquid and having a first side wall and a second side wall which face each other, a rear wall, an inlet, and a connecting portion; a conveying mechanism configured to convey a recording medium along a conveying path extending in a first direction; a carriage configured to move in a second direction in which the first side wall and the second side wall face each other so as to define a movement area having a range in the second direction, the range of the movement area having first and second ends spaced apart in the second direction; a tube connected to the connecting portion; and a head mounted on the carriage and having a nozzle configured to jet the liquid onto the recording medium conveyed by the conveying mechanism.

Liquid jetting apparatus

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 jetting apparatus includes a casing, a tank formed with a liquid storage chamber which stores liquid, an inlet which allows the liquid to be poured into the liquid storage chamber, and a liquid outflow channel which allows the liquid to flow out from the liquid storage chamber, a conveying mechanism which conveys a recording medium along a conveying path extending in a front-rear direction, a carriage which moves in a left-right direction, and a head mounted on the carriage and having a nozzle which jets the liquid onto the recording medium conveyed by the conveying mechanism. The tank, the conveying path, and the carriage are arranged inside the casing, the tank is arranged outside the conveying path in the left-right direction, and at least a part of the tank is arranged inside both ends of a movement area of the carriage in the left-right direction.

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.

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 front surface, a rear surface, a storage chamber, a supply portion having a supply port, an upper surface, an electrical interface disposed at the upper surface, and a locking surface. The printing-fluid cartridge inserted in the printing-fluid consuming apparatus is pivotable between the first posture and a second posture. The electrical interface is positioned closer to the supply port than the locking surface is to the supply port in the insertion direction. The electrical interface is positioned rearward relative to the pivot center in the insertion direction. The locking surface is positioned upward relative to the storage chamber and closer to a rearmost point of the printing-fluid cartridge than to the electrical interface in the insertion direction.

A liquid cartridge includes a liquid chamber with a liquid outlet configured to supply the liquid from an interior of the chamber to an exterior of the chamber. An actuator is movable between a first position in which the liquid outlet is closed, and a second position in which the liquid outlet is open. A detector is positioned in the chamber, and is movable from a restricted position to a released position in response to movement of the actuator from the first to the second position. The detector is movable from the released position to the restricted position in response to movement of the actuator from the second to the first position.
