A liquid storage container including a positioning configuration contributing to downsizing is provided. The container capable of storing liquid therein includes a fitting portion including a communication port establishing communication between an inside and an outside, wherein a supply member supplying liquid is fitted and can supply the inside with liquid via the communication port; a first positioning portion positioning the supply member at one point; and a second positioning portion including a guide provided in the fitting portion and capable of guiding the supply member to a position where the supply member is fitted into the fitting portion when the supply member is fitted into the fitting portion while being positioned by the first positioning portion and a restriction portion restricting movement of the supply member using the first positioning portion as a rotation axis in the position where the supply member is fitted into the fitting portion.

Liquid storage container

A printing apparatus includes a liquid container. The liquid container includes a storage portion configured to store a liquid to be supplied to a discharge head that discharges the liquid, a first channel configured to be inserted into a replenishing bottle, which is configured to replenish the liquid to the storage portion, and to communicate with the replenishing bottle, and a second channel between the first channel and the storage portion, the second channel including, at an end portion on a side of the first channel, a first shape portion having a sectional shape common to a part of a sectional shape of the first channel.

Printing apparatus and liquid container

A printing apparatus includes a support member configured to support a printhead that performs printing by discharging ink to a print medium, a connecting member including a connecting portion connected to an ink introduction portion of the printhead and through which the ink introduction portion communicates with an ink supply passage via the connecting portion, a rotation member configured to hold the connecting member such that a posture of the connecting member is changeable, and configured to be supported by the support member to be rotatable between a connecting position at which the ink introduction portion and the connecting portion are connected and a connection releasing position at which the ink introduction portion and the connecting portion are not connected, and a biasing portion configured to bias the connecting member to a first posture with respect to the rotation member.

Printing apparatus and printhead

A liquid discharge apparatus includes a liquid container and an operating member. The liquid container is configured to introduce liquid from a liquid introducing portion to an inside. The operating member is configured to rotate around a rotation shaft in a first direction from a first position for covering the liquid introducing portion to move to a second position for exposing the liquid introducing portion, and rotate in a second direction opposite to the first direction from the second position to move to the first position. The operating member includes a plug member and a covering portion. The plug member is retained to the operating member by a retaining member and configured to plug the liquid introducing portion at the first position. The covering portion is configured to cover the plug member in a direction intersecting with the first direction.

Liquid discharge apparatus having liquid container and operating member

A liquid ejection apparatus includes a first liquid storage container, a second liquid storage container, a first terminal member, a second terminal member, and a circuit board. The first liquid storage container stores liquid to be supplied to a liquid ejection head that ejects the liquid to an ejection medium. The second liquid storage container is arranged side by side in a first direction with respect to the first liquid storage container. The first terminal member comes into contact with the liquid stored within the first liquid storage container. The second terminal member comes into contact with liquid stored within the second liquid storage container. The circuit board comes into contact with the first terminal member and the second terminal member and relatively moves in the first direction with respect to the first liquid storage container.

Liquid ejection apparatus

A liquid discharge apparatus includes a liquid discharge head to discharge liquid to a medium and a liquid storage container. The liquid storage container includes a reservoir portion, a liquid injection portion, a liquid holding unit, and a liquid guide portion. The reservoir portion reserves the liquid that is supplied to the liquid discharge head. The liquid injection portion allows a liquid injection container for injecting the liquid into the reservoir portion to be inserted in the liquid injection portion in a first direction. The liquid holding unit is provided at a position spaced apart from the liquid injection portion and is capable of holding the liquid. The liquid guide portion guides the liquid from the liquid injection portion to the liquid holding unit in a second direction intersecting with the first direction.

Liquid discharge apparatus and liquid storage container

A recording apparatus includes a recording head having discharge orifices arranged on a discharge orifice surface, a cap, a wiper, and a moving unit that moves the wiper in a first direction. When the cap covers the discharge orifice surface, a first member is disposed at an inside wall of the cap at a position near a first side of a region having the discharge orifices, and a second member is disposed at another inside wall of the cap at a position near a second side of the region having the discharge orifices. The first side faces in a direction opposite to the first direction and the second side faces in the first direction. In a direction normal to the discharge orifice surface, a distance between the second member and the discharge orifice surface is smaller than a distance between the first member and the discharge orifice surface.

Recording apparatus

A recording apparatus includes a wiper, a recording head having a step portion and an ejection port surface supporting an ejection port, and a moving unit to relatively move the wiper and the recording head so that the wiper moves with respect to the recording head in relative movement in a first direction. In a first wiping, the relative movement causes the wiper to stop at or in vicinity of the step portion, or pass at or in the vicinity of the step portion at a speed lower than a speed at which the wiper wipes an area in which the ejection port is arranged. In a second wiping performed after the first wiping, the relative movement causes the wiper to pass through the step portion of the recording head and wipe the recording head in the first direction toward the area, and thereafter wipe the area.

Recording apparatus and wiping method

A recording apparatus includes a recording head having an ejection port surface and a step portion, a blade to wipe the ejection port surface, and a moving unit. A plurality of ink ejection ports is arranged on the ejection port surface. The moving unit performs relative movement of the blade and the recording head by moving the blade or the recording head in a first direction to cause the blade to wipe a wiped surface including the ejection port surface, from the step portion to an area in which the plurality of ink ejection ports is arranged. The moving unit performs the relative movement so that a first relative velocity of the relative movement when the blade passes the step portion is higher than a second relative velocity of the relative movement when the blade, that has been in contact with the wiped surface, is separated from the wiped surface.
