Abstract
A liquid supply device that supplies a liquid to a head that ejects the liquid to an object includes a liquid storage chamber, an air introduction port, an atmospheric release flow path where one end is in communication with the air introduction port and another end is open to the atmosphere, and an air storage chamber configured to store air and provided in a portion of the atmospheric release flow path. A liquid supply flow path that supplies the liquid from the liquid storage chamber to the head is formed in a wall defining the air storage chamber. Thus, the size of a liquid ejection system is reduced.

A liquid supply device that supplies a liquid to a head that ejects the liquid to an object, the liquid supply device comprising:
- a liquid storage chamber configured to store the liquid;
- a liquid injection portion in communication with the liquid storage chamber, and configured to inject the liquid into the liquid storage chamber;
- an air introduction port that is an opening provided in the liquid storage chamber to introduce air into the liquid storage chamber;
- an atmospheric release flow path where one end is in communication with the air introduction port, and another end is open to the atmosphere;
- and
- an air storage chamber configured to store air, and provided in a portion of the atmospheric release flow path;
- wherein a liquid supply flow path that supplies the liquid from the liquid storage chamber to the head is formed in a wall defining the air storage chamber.
