    • The present invention relates to an electronic pen recognizing the position in a coordinate system with the reaction of the magnetic field in an electronic device such as a computer, a smartphone, a tablet PC. More particularly, the present invention relates to an electronic pen having multiple core structures having a magnetic field focused to the pen for the reaction with a metal sheet to be generated at the end of the electronic pen. The present invention provides an electronic pen for recognizing positions having multiple cores enabling stable and accurate position recognition by controlling an inductance value to be large while controlling the rate of change to be low through shortening the path of a flux line and controlling an area to be small by enabling the induction flux line of the electronic pen to be focused by a second core.
