Liquid storage container and liquid ejecting apparatus

A liquid supply device includes a first shell having a liquid storage chamber configured to store liquid and a liquid inlet portion through which the liquid is poured to the liquid storage chamber, a second shell that is a different member from the first shell, a holding member for holding a mutual positional relationship between the first shell and the second shell to be constant, and an atmospheric communication channel that makes outside and the liquid storage chamber communicate with each other.

Liquid supply device, liquid jetting system, and liquid jetting device

A liquid ejection apparatus has a liquid ejection head that has nozzles for ejecting liquid, a liquid container that has a liquid replenishing port through which the liquid is replenished from the outside, a plug member that can close the liquid replenishing port by being positioned at a closing position and open the liquid replenishing port by being positioned at an open position, a carriage configured to arrange the liquid ejection head and the liquid container, a cap configured to cap the nozzles so as to cover the nozzles, and a control unit, assuming that a state where the nozzles are covered by the cap is a capping state and a state where the nozzles are not covered by the cap is a non-capping state, configured to bring the nozzles and the cap into the non-capping state before removing the external container from the liquid replenishing port.

Liquid ejection apparatus

Provided is a liquid tank in which air bubbles are less likely to remain in a valve mechanism provided in an on-carriage-type liquid tank. The liquid tank has a liquid supply portion, a first liquid chamber, a second liquid chamber that can contain the liquid to be supplied to the first liquid chamber, and a valve mechanism that is arranged between the first liquid chamber and the second liquid chamber, and the valve mechanism has, inside an exterior wall constituting the valve mechanism, a channel member, a biasing member, a valve body, and a rod from an upstream side of flow of the liquid in the stated order, the channel member is provided inside the biasing member, and includes a first channel in which the liquid can pass, and the exterior wall and the biasing member form a second channel through which the liquid can pass therebetween.

A waste liquid container includes a waste liquid vessel having a mounting face, a first side face, and a bottom face that are outer surfaces intersecting each other, a waste liquid inlet disposed on the mounting face, a circuit board having a connection terminal disposed along the first side face, and a first recess portion that opens in the mounting face and the bottom face below the waste liquid inlet. In the waste liquid container, when a width direction is defined as a direction in which both the mounting face and the bottom face extend, the first recess portion is disposed at a position between the waste liquid inlet and the connection terminal in the width direction.

Waste liquid container and attachment

A liquid ejecting apparatus includes a liquid ejecting head that ejects a liquid, a subsidiary tank connected to the liquid ejecting head, and a main tank capable of supplying the liquid to the subsidiary tank. The subsidiary tank is provided with a liquid introducing portion that receives the liquid from the main tank. The liquid introducing portion includes a receiving member that receives the liquid from the main tank. The receiving member is a porous member that seals the pressure chamber by being impregnated with the liquid. The main tank includes a reservoir portion in which the liquid is stored and a connecting flow path that extends from the reservoir portion. The connecting flow path includes a terminal portion that is connectable to and disconnectable from the liquid introducing portion.

Liquid ejecting apparatus

A liquid ejecting apparatus includes a liquid ejecting head configured to eject liquid onto a medium, a mounting portion on which a liquid collection container including an absorber that absorbs liquid is removably mounted, a liquid receiving portion configured to receive the liquid ejected by the liquid ejecting head, and a relay portion located in a region communicating with the liquid receiving portion. The relay portion is located at a position in contact with the absorber of the liquid collection container mounted in the mounting portion.

Waste liquid reservoir and liquid ejecting apparatus

A waste liquid container is detachably mounted on a mounting unit which includes a discharge portion discharging a waste liquid and a projection to which a substrate connection portion is joined. The waste liquid container includes: a containing portion that is able to contain the waste liquid; a connection concave portion that is opened in a mounting direction; a circuit substrate that includes connection terminals electrically connected to the substrate connection portion and is joined to the connection concave portion; and a waste liquid introduction portion that is connected to the discharge portion.
