<P>PROBLEM TO BE SOLVED: To discriminate a plurality of postures of a second body to a first body by using one magnet and two magnetic field sensors, in a rotary electronic apparatus in which the first body and the second body are coupled with each other through a two-axis hinge mechanism 3. <P>SOLUTION: In a rotary electronic apparatus, a second body includes a magnet 4 having an N-pole 41 and an S-pole 42, and a first body includes an N-pole magnetic field sensor 5 and an S-pole magnetic field sensor 6. The magnet 4 is installed in a posture having a magnetizing direction axis tilted to a second hinge axis 8. The S-pole magnetic field sensor 6 is disposed at a position which is on an extension line of the magnetizing direction axis of the magnet 4 and receives a magnetic field from the S-pole 42, in one state of a plurality of states, and the N-pole magnetic field sensor 5 is disposed at a position which is on the extension line of the magnetizing direction axis of the magnet 4 and receives a magnetic field from the N-pole 41 in another state. <P>COPYRIGHT: (C)2013,JPO&INPIT |
