[Industrial applications]

 The present invention relates to an improvement in a stamp using a printing body made of a porous stamp material having innumerable continuous pores.

[0002]

[Prior art]

 Conventionally, there has been known a seal stamp that does not need to be adhered to the red meat and the like each time it is used, using a printing body formed of a multi-pore printing material having a large number of continuous pores such as sponge rubber so that it can absorb ink. Has been. It is also known that those seals are unitized and detachably attached to the rear end of the shaft cylinder of the writing instrument or the tip of the shaft cylinder of the seal holder. By the way, in the conventional stamp, the imprint becomes thin as the ink impregnated in the printing body and the ink occlusion body is consumed with the imprinting. In that case, a method is usually used in which ink is dripped from the printing surface of the printed material to allow the ink to soak into the ink. In that case, it takes time to infiltrate the ink and is troublesome. There is also a method of dropping the ink from the rear end of the ink occlusion body, but problems such as spilling the ink and soiling the surrounding area are likely to occur. In addition, the amount of ink dripped is moderate, which causes problems such as overfilling and imprinting of the imprint. There is also a method in which an ink storage rod which is in close contact with the rear end of the ink storage member and is impregnated with a large amount of ink is arranged, but there is a problem that the structure is complicated and the cost is high.
