The present invention relates to a marker pen, and more particularly, to a marker pen, in which ink is smoothly and rapidly supplied by controlling an ink supply amount, and the re-supplying of the ink is convenient. To this end, the marker pen comprises a pen point fixing element slidably mounted at a leading end of an inner case; a sponge case mounted in the pen point fixing element; a valve, in which a cutoff stopper is formed at a lower end of a guide bar for composing a first outlet in a stepped part of the inner case, a peripheral valve through hole is formed to be connected to the guide bar and the cutoff stopper, and a second outlet is formed between a holding protrusion formed at a lower end of the cutoff stopper and a leading end of a sponge case which is held by the holding protrusion; a spring base inserted into the leading end of the inner case; and an ink tank fitted into the leading end of an outer case. The marker pen enables writing without breaks in the ink flow through a smooth ink supply via a through hole and the valve through hole, and provides the advantage of a quick supply of ink by supplying more ink to the sponge through the first and the second outlet. The manufacturing of an ink tank for separate sale by combining the ink tank with an additional cap is also enabled. |
