PROBLEM TO BE SOLVED: To prevent an application liquid from reversing even when the applicator is used facing upward by arranging a tip at the tip end side of an application liquid-feeding valve, bringing the rear end section of the tip into contact with the valve disc, and at the same time, arranging a check valve between the application liquid-feeding valve and an application liquid tank. SOLUTION: When a fiber bundle tip pen 1 as an applicator is used, a tip 5 is pushed in by a writing pressure, and the valve disc 12 of an ink feeding valve 6 retracts, and the opening of a housing 11 is opened. Then, at the time of a facing downward writing, the valve body 31 of a check valve 30, which is arranged between the ink feeding valve 6 and an ink tank 3, is opened, and an ink can be fed by a small amount into the valve chest 11 of the ink feeding valve 6. Therefore, the ink can be prevented from dropping down. On the contrary, at the time of a facing upward writing, the valve disc 31 of the check valve 30 is closed, and the ink in the ink tank 3 and a closing material 8 can be prevented from reversing. Therefore, the discharging of the ink and the closing material 8 from the rear end section of the ink tank 3 can be eliminated. |
