Abstract: A position indicator includes a tubular core member comprising a first magnetic core, a second magnetic core, a first coil, a second coil, a rod, a pen-pressure detecting element, a capacitor, and a switch. At least one of the first and second magnetic cores includes a recessed portion extending in the axial direction so as to form a through-hole when the first and second magnetic cores are combined, and the rod is inserted through the hole. The first coil is wound around the tubular core member, and the second coil is wound around the second magnetic core. The pen-pressure detecting element detects a pressure applied to an end of the rod (i.e., the pen tip). The capacitor is connected to the first coil to form a resonant circuit. The switch controls “on” and “off” states of the second coil to calculate a rotation angle of the position indicator.

Abstract: A position indicator includes a tubular core member, a first coil, a second coil, a substantially bar-like rod, a pen-pressure detecting element, at least one capacitor, and a switch. The tubular core member is formed by a substantially bar-like first magnetic core and a substantially bar-like second magnetic core, which are combined in a transversal direction thereof to form a through-hole therebetween. At least one of the first and second magnetic cores may include a recessed portion formed therein extending in the axial direction thereof. The first coil is wound around the tubular core member, and the second coil is wound around the second magnetic core. The rod is inserted into the through-hole of the tubular core member. The pen-pressure detecting element detects a pressure applied to an end of the rod (i.e., the pen tip). The capacitor is connected to the first coil to form a resonant circuit.
