PURPOSE:To supply the pen tip with a stable amount of ink by providing a disposable tank to an ink vessel of a recorder written in ink via a constant liquid-surface controller. CONSTITUTION:When a record is performed with a pen and the ink 11 in a vessel main body 1 is flowed out via a capillary tube 10 by a capillary phenomenon, since the liquid surface 11a of the ink is detached from the lower end surface of the short side of the constant liquid-surface controller 17 and air is flowed in the disposable tank 15, the ink 11 is flowed in the vessel main body 1 until the constant liquid surface is attained. In this way, the liquid surface 11a of the ink 11 in the vessel main body 1 is kept constant at all times. Hereby, the stable amount of ink can be supplied to the pen tip and further, the tank capacity can be increased or decreased according to a necessary amount of the ink and moreover, the workability at the time of replenishing the ink is improved. |
