ABSTRACT:
An input device has an exciting coil for generating a predetermined exciting magnetic field. First and second coils are displaced from each other by a predetermined distance in a predetermined direction and capable of generating an induced electromotive voltage when excited by the exciting coil. Third and fourth coils are displaced from each other by a predetermined distance in the predetermined direction and capable of generating an induced electromotive voltage when excited by the exciting coil. The third and fourth coils are displaced by a predetermined distance from the first and second coils, and all of the coils are similarly constructed.
