A coordinates input apparatus for designating a particular set of coordinates in three-dimensional space, the coordinates input apparatus includes a substantially box-like frame, an operating part tiltably positioned within the frame, a printed circuit board supporting the frame, a magnet, a plurality of magnetoelectric transducers and a magnetic plate. The magnet and the plurality of magnetoelectric transducers are fixedly mounted on an upper surface of the printed circuit board opposite the magnetic plate, the magnet is disposed so that one pole faces the magnetic plate, the magnetic plate is disposed on a lower surface of the operating part opposite the magnet and tiltably supported by the frame via the operating part, the plurality of magnetoelectric transducers are disposed around an outer rim of the magnet and output voltage signals indicating voltage values that vary according to a change in distance between the magnetoelectric transducers and the magnetic plate, such that the voltage signals indicate a set of coordinates in three-dimensional space.
