Abstract
A liquid ejecting device includes a head having a nozzle configured to eject liquid, a container that is connected with the head and is configured to store the liquid, a communication section configured to communicate an internal space of the container with atmosphere, and a liquid reservoir configured to store the liquid and to be removably attached to the container. An internal space of the liquid reservoir is communicated with the internal space of the container through a liquid flow path and a gas flow path in an attached state where the liquid reservoir is attached to the container.
Claims27
A liquid ejecting device comprising:
- a head having a nozzle configured to eject liquid;
- a container connected with the head, the container being configured to store the liquid;
- a communication section configured to communicate an internal space of the container with atmosphere;
- and
- a liquid reservoir located outside the head and configured to store the liquid and to be removably attached to the container, wherein an internal space of the liquid reservoir is communicated with the internal space of the container through a liquid flow path and a gas flow path in an attached state where the liquid reservoir is attached to the container, and
- wherein in the attached state, when a first liquid-filled region in the internal space of the container is in communication with a second liquid-filled region in the internal space of the liquid reservoir via the liquid flow path, a second gas-filled region in the internal space of the liquid reservoir is in communication with a first gas-filled region in the internal space of the container via the gas flow path and in communication with the atmosphere via the communication section of the container, without any liquid-filled regions interposed between the second gas-filled region and the atmosphere, and wherein the first gas-filled region directly contacts the first liquid-filled region and the second gas-filled region directly contacts the second liquid-filled region.
A liquid reservoir comprising:
- a first reservoir valve disposed at a liquid flow path in an attached state where the liquid reservoir is removably attached to a container of a liquid ejecting device;
- and
- a second reservoir valve disposed at a gas flow path in the attached state, the liquid flow path and the gas flow path being configured to, in the attached state, communicate an internal space of the container with an internal space of the liquid reservoir,
- wherein the first reservoir valve and the second reservoir valve are configured to:
- change from a closed state into an open state in response to a transition from a separated state where the liquid reservoir is not attached to the container to the attached state;
- and
- change from the open state into the closed state in response to a transition from the attached state to the separated state, and
- wherein in the attached state, when a first liquid-filled region in the internal space of the container is in communication with a second liquid-filled region in the internal space of the liquid reservoir via the liquid flow path, a second gas-filled region in the internal space of the liquid reservoir is in communication with a first gas-filled region in the internal space of the container via the gas flow path and in communication with atmosphere via a communication section of the container, without any liquid-filled region interposed between the second gas-filled region and the atmosphere, and wherein the first gas-filled region directly contacts the first liquid-filled region and the second gas-filled region directly contacts the second liquid-filled region.
