Abstract
A position measurement device for measuring a position of a pen is provided. The position measurement device includes a first sub-loop unit that includes at least one loop configured to apply an electrical current or measuring an electromagnetic field change; a second sub-loop unit having at least one loop configured to measure the electromagnetic field change; and a control unit configured to determine at least one loop of the first sub-loop unit as a transmission signal transmitting loop to thereby apply the electrical current to the transmission signal transmitting loop, and measure the position of the pen based on the electromagnetic field change measured by each of the at least one loop of the first sub-loop unit and each of the at least one loop of the second sub-loop unit.
