摘要： A first valve mechanism is a valve mechanism provided in a flow path coupled to a liquid ejecting head that ejects a liquid, and including a valve that opens/closes the flow path, a first communication liquid chamber that communicates with the flow path, and a first pressure receiving body that converts a pressure difference between a pressure of the first communication liquid chamber and a reference pressure into an operating force of the valve, in which a threshold pressure of the first communication liquid chamber for determining opening/closing of the valve is variable.

摘要： A liquid discharge unit includes a liquid discharge head having a first joint portion and configured to discharge a liquid in a first direction, a liquid supply section having a second joint portion joined to the first joint portion to supply the liquid to the liquid discharge head, and disposed in a second direction opposite to the first direction relative to the liquid discharge head, and a support section which is formed together with the liquid discharge head, and to which the liquid discharge head is fixed. With respect to the first direction, a position at which the liquid supply section is fixed to the support section is located in the second direction with respect to a position at which the first joint portion and the second joint portion are joined to each other.
