<P>PROBLEM TO BE SOLVED: To highly accurately detect an opening/closing state of an opening/closing body, which is capable of being configured by a fixed unit as well as a movable unit, regardless of a distance or a direction between the fixed unit and the movable unit. <P>SOLUTION: An opening/closing body comprises: a fixed unit arranged at a fixed section of an opening/closing body; and a movable unit arranged at a movable section of the opening/closing body supported by the fixed section. The movable unit has a magnetic field generation section. The fixed unit has a plurality of magnetic field detection sections to detect a magnetic field generated by the magnetic field generation section of the movable unit and an opening/closing state determination section to determine an opening/closing state of the opening/closing body in accordance with respective output voltages based on the respective magnetic fields detected by the plurality of the magnetic field detection sections. <P>COPYRIGHT: (C)2012,JPO&INPIT |
