The casing includes a top surface (39, 91); a liquid chamber (32) storing liquid therein; and a liquid passage (35) extending in a first direction in an upright posture. The top surface faces upward in the upright posture and formed with a recess (68). The movable member has a light blocking portion (67A). The light blocking portion in the upright posture is configured to move between a first position and a second position. At least a part of the light blocking portion in the first position is positioned above the top surface in the upright posture. The urging member is configured to urge the movable member toward the first position.

摘要： A printing-fluid cartridge (30) is inserted into a printing-fluid consuming apparatus (10) in an insertion direction (51) crossing a gravitational direction (53) and attached thereto in a first posture. The printing-fluid cartridge (30) includes a front surface (40), a rear surface (41), a storage chamber (32), a supply portion (34) having a supply port (71), an upper surface (39), an electrical interface (64) disposed at the upper surface (39), and a locking surface (151). The printing-fluid cartridge (30) inserted in the printing-fluid consuming apparatus (10) is pivotable between the first posture and a second posture about a pivot center (PP). The electrical interface (64) is positioned closer to the supply port (71) than the locking surface (151) is to the supply port (71) in the insertion direction. The electrical interface (64) is positioned rearward relative to the pivot center (PP) in the insertion direction (51). The locking surface (151) is positioned closer to a rearmost point (P5) of the printing-fluid cartridge (30) than to the electrical interface (64) in the insertion direction (51).

摘要： Therein is provided a liquid cartridge in combination with a printer having an attachment section to which the liquid cartridge is configured to be inserted in an insertion direction crossing a gravitational direction. The liquid cartridge is configured to be removed in a removal direction opposite to the insertion direction. The liquid cartridge is configured to be inserted into an attachment section of the printer in the insertion direction against an urging force acting in the removal direction. The liquid cartridge comprises a chamber storing liquid, a liquid outflow path provided with an outlet facing frontward in the insertion direction in a first posture of the liquid cartridge, the liquid outflow path extending from the chamber to the outlet in the insertion direction, a circuit board disposed rearward relative to the outlet in the insertion direction, a first surface configured to contact with an electrical contact of the attachment section, the first surface facing at least upwardly in the first posture, and a second surface configured to contact with the electrical contact of the attachment section, the second surface facing at least rearwardly in the first posture. The liquid cartridge is configured to move between the first posture and a second posture in which the second surface is spaced apart from the electrical contact of the attachment section in the gravitational direction. The circuit board includes at least one of the first surface and the second surface.

摘要： A liquid cartridge (30) configured to be inserted into a cartridge-attachment section (110) in an insertion direction includes a casing (31), and a lever (67) supported by the casing. The lever is pivotable about a pivot axis (X) between a first position and a second position. The lever (67) includes a light-blocking portion (67A) configured to block or attenuate light traveling in a widthwise direction crossing the insertion direction and a gravitational direction, and a force-receiving portion (67C) 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 (67A) is positioned lower at the second position than at the first position. The pivot axis (X) is positioned frontward of the light-blocking portion (67A) and rearward of the force-receiving portion (67C) 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 is configured to be inserted into a cartridge-attachment section (110) and includes a casing (31) and a light blocking portion (67). The casing includes a liquid chamber (32); a liquid passage (35) extending in a first direction; and a top surface (39, 91) facing upward. The light blocking portion is deformable between a non-deformed state and a deformed state. The light blocking portion, at least in the non-deformed state, is configured to block or attenuate light emitted from the cartridge-attachment section and traveling in a widthwise direction crossing the first direction and a gravitational direction in an upright posture. The light blocking portion in the non-deformed state is configured to be deformed to the deformed state by an external force. The light blocking portion returns to the non-deformed state when the external force is removed from the light blocking portion in the deformed state.
