PROBLEM TO BE SOLVED: To prevent magnetic interference between a plurality of sensors without using a magnetic shield member. SOLUTION: In an electronic equipment on which a plurality of combinations of sensors consisting of the combinations of magnetic force generators and magnetic force detectors for detecting the magnetic force generated by the magnetic force generators, the magnetic force generators of the sensors 16 and 20 are composed of electromagnets, respectively, and a control means 10 is provided, for making one sensor operate, while exciting the electromagnet of the one sensor and holding the electromagnet of the other sensor in a non-excited state when one sensor of the plurality of combinations of the sensors 16 and 20 operates. Accordingly, the magnetic interference between the plurality of sensors can be prevented. COPYRIGHT: (C)2005,JPO&NCIPI
