Claims

[Scope of utility model registration request]

A rotating magnet that is rotatably held and arranged in a horizontal plane to detect earth's magnetism; a first and a second magnetically sensitive element; a first element that detects and electrically processes electrical signals obtained from the first and second magnetically sensitive elements in response to rotation of the rotating magnet;
, a second electric processing circuit, first and second coils to which electric signals processed by the first and second electric processing circuits are supplied and respectively generate mutually orthogonal magnetic fields; , a magnetic pointer rotatably arranged around the center with respect to the orthogonal magnetic field created by the second coil;
and a display device that displays the direction corresponding to the rotating magnet based on the rotation of the magnetic pointer that rotates with a sensitive port in response to an orthogonal magnetic field created by a second coil.
