Abstract:
A stamp making device which makes a pattern on a porous resin member including light energy absorbing material, said stamp making device comprising:a data input unit into which image data is inputted; an original printing unit including a thermal head and a platen which nip a transparent film and an ink ribbon therebetween, said thermal head being driven to print an image on said transparent film based on said image data, thereby to make a positive original film; an irradiation unit including a transparent support plate fed said original film and a light source which applies light to said porous resin member through said original film; an original feeder which feeds said original film to said irradiation unit from said original printing unit; and a biasing unit which biases said porous resin member against said original film on said transparent support plate thereby decreasing a thickness of a portion of said porous resin member such that when light is applied by said irradiation unit to said porous resin member through said original film, an irradiated portion of said porous resin member is melted and becomes relatively rigid while an unirradiated portion is relatively elastic and incapable of being impregnated with ink.
