A liquid discharge device is provided with a discharge head, a sub tank, and a liquid replenishment device comprising a space for housing a main tank and a joint member to be connected to the main tank. The joint member is capable of being connected to and disconnected from the sub tank. The liquid within the main tank is supplied to the sub tank when the joint member is in a connected state with the sub tank. The joint member comprises a liquid path and a valve biased in a direction where the liquid path is closed. The joint member is configured to receive a force from the sub tank and open the liquid path in the case where the joint member is being connected to the sub tank. The joint member is configured to open the liquid path in the case where an inner space of the main tank has a negative pressure greater than a first value. |
