PROBLEM TO BE SOLVED: To provide an invertible ink stamp avoiding leakage of ink from an ink pad side even if internal pressure of an ink tank increases.SOLUTION: In an invertible ink stamp, an ink absorber/retainer member 3 is disposed on a top face side of an ink pad 6, an absorbent member 31 having capillary attraction weaker than that of the ink absorber/retainer member 3 and absorbing excessive ink, is disposed on the top face side of the ink absorber/retainer member 3, and an ink tank 2 having an ink supply tube 21 whose distal end is open, is disposed on the top face side of the absorbent member 31. A wall member surrounds the whole circumferential surface of the ink absorber/retainer member 3 and the absorbent member 31 for avoiding leakage of ink. Part of or the entire lower face of the ink absorber/retainer member 3 is open and includes an ink discharge vent 3a, and part of or the entire outer face of the absorbent member 31 is open and includes an air flow vent 31a which communicates with the atmosphere. The distal end of the ink supply tube 21 is connected to the ink absorber/retainer member 3. |
