MAGNETIC TYPE ATTITUDE SENSING SENSOR AND ELECTRONIC EQUIPMENT USING THE SAME

Title:

MAGNETIC TYPE ATTITUDE SENSING SENSOR AND ELECTRONIC EQUIPMENT USING THE SAME

Document Type and Number:

Japanese Patent JP2006098320

Kind Code:

A

Abstract:

To provide a magnetic type attitude sensing sensor simple in configuration and mountable on portable electronic equipment, and also to provide the electronic equipment.

The magnetic type attitude sensing sensor applies first and second bias magnetic fields 19 and 20 mutually orthogonal to first and second Wheatstone bridge circuits 21 and 22 being magnetic detection means respectively, and detects the attitude of the equipment by utilizing the fact that differential voltage of the Wheatstone bridge circuit applying the bias magnetic field of a horizontal direction is constant when on bias magnetic field is vertical and the other bias magnetic field is horizontal.
