Abstract
In order to supply a multiple number of inks at a desired geometry, a filling frame has filling ports of substantially vertical passage holes. A stamp piece has a continuous porous structure and is placed on a base plate with the filling framed laid thereover. Each ink is supplied from a corresponding filling port to a separated area and is impregnated into a stamp piece in substantially the same geometry as that of separated area so that each will not mix with the other. Thus, inks are filled keeping the separation, into the stamp piece having a continuous porous structure laid below the filling frame.
