Abstract
Official abstract text for this publication.
A supply device that supplies a liquid to a liquid ejecting head, includes one or more tanks that house the liquid; a liquid flow path coupled to the one or more tanks and the liquid ejecting head; and a pressure-adjusting portion that adjusts a pressure in the one or more tanks. The one or more tanks are provided between the pressure-adjusting portion and the liquid flow path. The pressure-adjusting portion includes a communication path that communicates with the one or more tanks, a pressure chamber provided with a diaphragm and coupled to the communication path, and an urging portion that urges the diaphragm in a direction in which the pressure chamber expands.
First claim
Opening claim text (preview).
What is claimed is: 1. A supply device that supplies a liquid to a liquid ejecting head, the supply device comprising: one or more tanks that house the liquid; a liquid flow path coupled to the one or more tanks and the liquid ejecting head; and a pressure-adjusting portion that adjusts a pressure in the one or more tanks, the pressure-adjusting portion being a self-sealing valve, wherein the one or more tanks are provided between the pressure-adjusting portion and the liquid flow path, the pressure-adjusting portion includes a communication path that communicates with the one or more tanks, a pressure chamber provided with a diaphragm and coupled to the communication path, and an urging portion that urges the diaphragm in a direction in which the pressure chamber expands, and the inside of the communication path and the self-sealing valve contains only air when pressure is adjusted such that no liquid enters the communication path or the self-sealing valve. 2. A liquid ejecting apparatus comprising: the supply device according to claim 1 , wherein the liquid ejecting head ejects the liquid onto a medium to form an image. 3. The liquid ejecting apparatus according to claim 2 , further comprising: a carriage provided with the liquid ejecting head; and a movement mechanism for reciprocating the carriage with respect to the medium, wherein the carriage is provided with the one or more tanks. 4. The liquid ejecting apparatus according to claim 3 , wherein the carriage is provided with a plurality of the tanks. 5. The liquid ejecting apparatus according to claim 4 , wherein the plurality of the tanks communicate with the pressure-adjusting portion. 6. The liquid ejecting apparatus according to claim 3 , wherein the carriage is provided with the pressure-adjusting portion.
