Abstract: A portable telephone includes an upper housing and a lower housing connected by a two-axis hinge. A magnet is built into the upper housing at a position spaced from the upper housing center axis passing the vertical axis (Y) of the two-axis hinge. Depending on the direction of the upper housing when the two housings are closed, the magnet comes to a position symmetrical about the center axis. Consequently, when MR sensors are arranged in the lower housing at positions corresponding to the above positions, the direction of the upper housing can be determined. Four elements in total are conventionally required to detect the direction of a housing; however, the device enables housing detection by three elements in total: one magnet, two MR sensors. The number of elements necessary to detect the direction of a housing is reduced, as is the area for mounting the elements.
