Abstract
A solvent container (), an additional solvent container (), a liquid delivery pump (), a flow path structure () including a connection flow path () a suction flow path (), and a flow path opening/closing mechanism () for opening and closing the suction flow path () of the flow path structure () are included. The connection flow path () has a first end and a second end, the first end is inserted into the solvent container (), and the second end is inserted into the additional solvent container (). The suction flow path () is fluidly connected to the connection flow path () at a position between the first end and the second end of the connection flow path (). When both ends of the connection flow path () are immersed in the solvent and the connection flow path () is filled with the solvent, the solvent flows in the connection flow path () due to a relationship between a liquid level height of the solvent in the solvent container () and a liquid level height of the solvent in the additional solvent container (), so that the solvent is supplied from the additional solvent container () to the solvent container () in response to a decrease in the solvent in the solvent container ().
