Abstract
A coordinate-position detecting device comprising a white board as a coordinate-position entry area, and three reflecting members each for recursively reflecting light from two optical units. The angle between the write-in surface of the white board and the reflecting surface of the reflecting member at the bottom is an obtuse angle. Further, of angles obtained by dividing the above angle by a horizontal surface, the angle between the horizontal surface and the reflecting surface is an acute angle.
