Abstract
A position indicator is provided. The position indicator includes an external case, and a core having an indicating unit projecting outside of the case. The core is movably supported by the case. The core has a central axis extending along a lengthwise direction thereof. A guiding unit includes an inclined plane provided on one of the case and the core. An engaging unit is provided on the other one of the case and the core. The engaging unit is slidably engaged with the inclined plane such that the guiding unit guides movement of the core when external force is applied to the indicating unit of the core in a lateral direction with respect to the central axis of the core. A pressure detector is operably associated with the core for detecting pressure applied to the indicating unit based on the movement of the core with respect to the case via the guiding unit.
