<P>PROBLEM TO BE SOLVED: To provide a triaxial magnetic type acceleration sensor and a compact acceleration geomagnetism detector. <P>SOLUTION: An acceleration sensor of each axis in this triaxial magnetic type acceleration sensor comprises a plate spring, a detecting magnet supported by the plate spring to be displaced along a direction opposite to a detection-directional acceleration, and constituting a magnetic circuit comprising a yoke and a gap of a soft magnetic material, and a magnetic field detecting element for detecting a magnetic field along a direction perpendicular to a longitudinal direction of the gap, the each plate spring of the each acceleration sensor is fixed to the same block, The Z-axial acceleration sensor is arranged within an angle range of 90° ranging from an angle position of the X-axial acceleration sensor up to an angle position of the Y-axial acceleration sensor, and this compact acceleration geomagnetism detector of the present invention comprises the triaxial magnetic type acceleration sensor and a geomagnetic sensor arranged on the same diagonal line of a quadrangle package to make the magnetic field detecting elements most separated each other, and respective detecting circuit parts thereof. <P>COPYRIGHT: (C)2007,JPO&INPIT |
