Coordinate output device, pen-shaped device, and electronic equipment

Abstract

Disclosed herein is a pen-shaped device having a pen tip, the pen-shaped device that includes a relative coordinate detecting device that, in operation, detects relative coordinates indicating changes in a position of the pen tip, and a signal transmitter circuit that, in operation, transmits a signal usable to detect absolute coordinates of the pen tip in a predetermined region. The relative coordinate detecting device includes an optical device including a light source that, in operation, emits light and an imaging part that, in operation, images reflected light of the light emitted from the light source.
