Abstract:
1. A pointing device comprising: a plurality of magnetic sensors placed on a printed circuit board; an elastic member mounted on said printed circuit board the elastic member having a hollow for enabling sway in any desired direction; a rigid pushing member placed on said elastic member; and a magnet mounted on said elastic member or said pushing member, wherein said elastic member is adapted to be deformed by an external force and to return the magnet to an initial position when the external force is removed, said hollow being enclosed by said printed circuit board, and said plurality of magnetic sensors detect magnetic flux density changes caused by a sway of said magnet due to elastic deformation of said elastic member, wherein said elastic member has a hollow that is made in such a manner that a portion where said magnet is placed and its neighborhood are made thinner than a remaining portion where the magnet is not placed.
