Abstract: A liquid cartridge is configured to be inserted into a cartridge-attachment section including a casing, a movable member, and an urging member. The casing includes a liquid chamber storing liquid therein; a liquid passage extending in a first direction in an upright posture, and a top surface. The top surface faces upward in the upright posture and formed with a recess. The movable member has a light blocking portion. 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.

Abstract: The liquid cartridge includes: a front surface facing in an insertion direction intersecting a gravitational direction; a rear surface spaced apart from the front surface in the insertion direction; an upper surface facing upward; a liquid supply portion disposed at the front surface; an electrical interface disposed at the upper surface; and a movable member including a detection portion. The movable member is movable between a first position and a second position. The movable member at the second position is positioned upstream in the insertion direction relative to the electrical interface. The movable member at the first position has a portion whose widthwise position is coincident with the electrical interface in a widthwise direction orthogonal to the insertion direction and the gravitational direction. The portion of the movable member at the first position is located downstream in the insertion direction or upward relative to the electrical interface.

Abstract: A liquid cartridge is configured to be inserted into a cartridge-attachment section including a casing and a light blocking portion. The casing includes a liquid chamber; a liquid passage extending in a first direction; and a top surface 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.

Abstract: A liquid cartridge configured to be inserted into a cartridge-attachment section in an insertion direction includes a casing, and a lever supported by the casing. The lever is pivotable about a pivot axis between a first position and a second position. The lever includes a light-blocking portion configured to block or attenuate light traveling in a widthwise direction crossing the insertion direction and a gravitational direction, and a force-receiving portion positioned closer to a front wall of the casing than the light-blocking portion is to the front wall in the insertion direction.

The pivot axis is positioned frontward of the light-blocking portion and rearward of the force-receiving portion 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.

Abstract: A liquid cartridge includes: a liquid container including a liquid storage chamber; a liquid supply portion including a liquid supply chamber and first and second openings; a movable member; a sealing member; and a connecting channel. The first opening provides communication between the supply chamber and an exterior of the cartridge. The second opening provides communication between the supply chamber and the storage chamber. The movable member extends in the storage chamber and the supply chamber. The sealing member intimately contacts the movable member and the liquid supply portion continuously in a circumferential direction. The connecting channel is formed in the movable member and provides communication between a space in the supply chamber and the storage chamber so that liquid can flow therebetween. The connecting channel opens into the storage chamber at a position further downward than the second opening when the cartridge is in an attached posture.

Abstract: A liquid cartridge includes: a casing including a liquid chamber; a liquid supply portion; a deformable member; a movable member; and an urging member. An internal pressure of the chamber is reduced as liquid flows out of the chamber. The deformable member protrudes from the casing in a cross direction crossing forward and rearward directions and has an internal space in communication with the chamber. The deformable member has such an elasticity that a dimension thereof in the cross direction becomes smaller as the internal pressure of the chamber is reduced. The movable member includes a detection portion, and a contact portion contacting the deformable member. The contact portion is in contact with the deformable member and disposed at one of positions further forward and further rearward relative to the deformable member. The urging member urges the movable member to move the contact portion toward the deformable member.
