A liquid discharge head having an element board including an element configured to discharge a liquid includes a first storage element and a second storage element. The first storage element is a fuse element or an anti-fuse element. The second storage element is a semiconductor memory capable of holding a larger capacity than the first storage element. The second storage element is provided on an area other than the element board.

Liquid discharge head and method of manufacturing the same

To provide a liquid storage container equipped with a plug member that can prevent leakage of a liquid from the liquid storage container and can be opened without causing scatter of the liquid, and a liquid ejection apparatus equipped with the liquid storage container. For the purpose, at least one of a connection part of the convex part with the cover part and an apical part of the convex part most apart from the connection part is provided offset from the centroid of the cover part, seen from a direction orthogonal to an opening surface of a supply port in a state that the plug member is mounted on a supply port of the liquid storage container.

A liquid container unit includes: a liquid container including: a plurality of liquid storage portions; and a plurality of injection ports which are provided to the respective plurality of liquid storage portions, and are configured to enable injection of liquid into the plurality of liquid storage portions; and an injection port cover which is provided to the liquid container so as to be rotatable and is configured to cover the plurality of injection ports so as to be openable and closable, the injection port cover including a plurality of stopper members configured to close the plurality of injection ports when the injection port cover is closed.

Liquid container unit and recording apparatus

There are provided a liquid container including a plug member which prevents leakage of a liquid from the liquid container and can be opened without scattering the liquid and a liquid ejection apparatus including the liquid container. For that purpose, a projecting portion in the plug member is provided below a center part of the plug member in a gravity direction in an attitude at the time of use of the liquid ejection apparatus.

Liquid container and liquid ejection apparatus

A liquid supplying mechanism includes: a tank including a liquid storage section configured to store a liquid, and a liquid injection port configured to inject the liquid into the liquid storage section; and a bottle configured to replenish the liquid into the tank. The bottle includes: a bottle section configured to store the liquid; and a protruding section, which protrudes from the bottle section, and is insertable into the liquid injection port so as to inject, into the liquid storage section, the liquid stored in the bottle section. The liquid injection port includes: a protruding section insertion portion into which the protruding section of the bottle is insertable; and a protruding section fixing portion, which is engageable with the protruding section of the bottle, to thereby be capable of fixing the bottle to the tank.

An object is to provide a liquid ejecting apparatus that enables a liquid storage container to be properly and easily refilled with a liquid from a liquid refilling container without causing color mixture in the liquid storage container. The liquid ejecting apparatus includes liquid storage containers each configured to feed the liquid to a liquid ejecting portion and liquid refilling containers each configured to refill the liquid storage container with the liquid. A first fitting unit is provided around a liquid injection port in each of the liquid storage containers. A second fitting unit is provided around a liquid pour-out port in each of the liquid refilling containers. The second fitting unit is fitted to the first fitting unit to enable the liquid to be delivered from the liquid pour-out port to the liquid injection port.

Liquid ejecting apparatus and liquid refilling container

A notification device can suppress the occurrence of a user's mistake in supplementing a printing liquid. An acquisition unit that acquires information relating to a residual amount of each of a plurality of printing liquids supplied to a printing apparatus and a determination unit that determines whether or not each of the plurality of printing liquids is a printing liquid of a notification target of which a residual amount is a predetermined amount or less based on the acquired information are included. In addition, a notification unit that, in a case where a plurality of printing liquids of the notification target determined by the determination unit are present, notifies of information relating to the residual amount of a predetermined printing liquid is included. This notification unit performs a notification with priority for a predetermined printing liquid satisfying a predetermined condition among the plurality of printing liquids of the notification target.
