Summary:PROBLEM TO BE SOLVED: To provide a reversal type stamp capable of sufficiently securing air-tightness of an ink pad, as well as allowing sealing with a small pressure.SOLUTION: A reversal type stamp 10 comprises: an outer cylindrical body 30; an inner cylindrical body 20 fitted into the outer cylindrical body 30 in a relatively movable manner; a coil spring 60 constantly energizing the inner cylindrical body 20 toward a protruding direction in the outer cylindrical body 30; a reversal body 40 reversed and returned in conjunction with slide movements of the outer cylindrical body 30 and the inner cylindrical body 20; and a stamping body 41 adhered to one surface of the reversal body 40. An ink cartridge 50 encasing a movable container 53 having an ink pad 52 is fitted into an upper part of the inner cylindrical body. An O-ring 43 disposed in the reversal body, seals an inside of the ink cartridge at a seal surface 51a, which receives the O-ring 43 and which is formed in a tapered shape.SELECTED DRAWING: Figure 5 【課題】インキパッドの気密性を充分確保することができ、しかも小さな押圧力で捺印することができる等の反転式印判を提供すること。【解決手段】反転式印判10は、外筒体30と、外筒体30に対し相対動可能に嵌装される内筒体20と、外筒体30内において内筒体20を突出方向に常時付勢するコイルバネ60と、外筒体30および内筒体20のスライド動作に連動して反転復帰する反転体40と、反転体40の一面に接着された印字体41とを備えている。内筒体の上部には、インキパッド52を有する可動容器53を収容するインキカートリッジ50が嵌合している。反転体に設けたOリング43を介してインキカートリッジの内部が密閉されるとともに、このOリング43を受けるインキカートリッジのシール面51aがテーパ状に形成されている。【選択図】図5
