An image recording apparatus includes: a housing formed with a first conveying path through which a sheet is conveyed; a head positioned above the first conveying path; a platen positioned below the first conveying path to face the head and which is moved between a first position and a second position farther from the head than the first position; an interference member positioned below the platen; and a discharge tray. The discharge tray is movable between a third position at which the discharge tray is installed in the housing and a fourth position at which the discharge tray is drawn from the housing. The interference member is movable between a fifth position at which the interference member contacts the platen being moved from the first position to the second position and a sixth position at which the interference member does not contact the platen positioned in the second position.

A liquid cartridge includes: a cartridge casing having a liquid storage chamber; a first wall; a second wall; and an air communication passage. The first wall is positioned upward relative to the liquid storage chamber. The second wall is positioned upward relative to the first wall. The air communication passage has a first communication hole in communication with the liquid storage chamber and a communication opening open to an atmosphere. The air communication passage includes: an air chamber defined by the first wall and the second wall and in communication with the liquid storage chamber through the first communication hole; a second communication hole formed in the second wall; and a labyrinth path. The labyrinth path is positioned upward relative to the air chamber, and has one end in communication with the second communication hole and another end in communication with the communication opening.

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 light-blocking portion is positioned lower at the second position than at the first position. 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.

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 system includes: a housing; a first tank; a second tank; a first reservoir configured to be connected to the first tank; a second reservoir configured to be connected to the second tank; and a liquid discharge head that ejects the liquid supplied from the first tank and the second tank. The housing includes: the first reservoir and the second reservoir includes: the first tank includes a first flow pipe, and the second tank includes a second flow pipe. The system further includes a circuit board that is disposed on the second outer wall and has a reservoir side contact that contacts the housing side contact.

A liquid discharging apparatus, having a liquid discharging head, a relatively-movable device, and a controller, is provided. The controller controls the liquid discharging head and the relatively-movable device to record a plurality of relative movement adjuster patterns, arranged at different positions in an arrayed direction, and a different pattern, arranged side by side with the plurality of relative movement adjuster patterns along a direction orthogonal to an arrayed direction on a same liquid-discharge objective medium. The controller controls the relatively-movable device, after recording at least one of the plurality of relative movement adjuster patterns, and before recording a next one of the plurality of relative movement adjuster patterns next to the at least one of the plurality of relative movement adjuster patterns, to perform a relative moving action by a moving amount different from a predetermined relative moving amount for recording the different pattern at least once.

A liquid cartridge is insertable into an attachment portion of a printing device in an insertion direction and attached thereto in an upright posture. The liquid cartridge includes: a housing defining a liquid chamber; a substrate; a contact; and a memory electrically connected to the contact. The substrate in the upright posture defines a sloped surface facing upward and sloping relative to a first imaginary plane extending in the insertion direction and a widthwise direction orthogonal to the insertion direction and a gravitational direction. The contact is formed on the sloped surface. An acute angle formed between the sloped surface and the first imaginary plane is greater than an acute angle formed between the first imaginary plane and a second imaginary plane passing through: a contact point between the contact and a contact of the device; and a lower end of a wall constituting a holder of the attachment portion.

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.
