[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. Further, it is known that those seals are unitized and detachably attached to the rear end of the shaft cylinder of a writing instrument or the tip of the shaft cylinder of a seal holder with an opening / closing lid that does not require attachment / detachment of a cap. By the way, as shown in FIG. 2, a conventional stamp holder has a cylindrical cover 9 ', which has a hole at the upper end thereof, and a print body 2'which can be impregnated with ink is housed therein. The cushion 4 "is placed on the lower surface of the print body 2", and the upper end of the shaft 6 "of the pedestal 5" with the shaft 6 "above the collar 7" and the shaft 8 "below is exposed. The cover 9 "and the shaft 6" are fixed to each other with the lower surface of the cushion 4 "in contact with each other. In the seal stamp unit having such a structure, the ink occluded in the print body 2'is consumed together with the stamp, and the seal image usually becomes thin after stamping several hundred times. At that time, the ink is replenished by dripping from the printing surface 3 ', but the viscosity of the ink is high and it takes a long time for the ink to permeate the print medium. Therefore, there is a problem that the printing surface becomes sticky during this time and printing cannot be performed. Further, the ink drools drastically and the seal cannot be stored until the ink has permeated to some extent.
