Elektromagnetisches Eingabegerät

摘要

An input device comprises an exciting coil (24) for generating a predetermined exciting magnetic field. First and second coils (26C, 27C) are displaced from each other by a predetermined distance in a predetermined direction and are capable of generating an induced electromotive voltage when excited by the exciting coil (24). Third and fourth coils (28C, 29C) 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 (28). The third and fourth coils (28C, 29C) are displaced by a predetermined distance from the first and second coils, (26C, 27C) and all of the coils (26C, 27C, 28C, 29C) are similarly constructed.
