<p>[PROBLEMS] A portable mobile apparatus where two magnetic detection means and a reduced number of magnets can specify in which of the following four states the housings of the apparatus are: a state where the housings are opened, a state where the housings are closed, a state where the housings are closed with a display reversed to face the outside, and a state where the display is turned 90 degrees with the housings closed and the display reversed to face the outside. [MEANS FOR SOLVING PROBLEMS] The portable mobile apparatus has a display housing (11), an operation housing (21), a universal hinge (30) that enables both housings (11, 21) to be opened and closed at a connection end and enables the display housing (11) to rotate about an axis (B) that is normal to a display surface (11A) and about an axis (C) that is in parallel with the display surface (11A), a first magnet (12) and a second magnet (13) that are installed at the display housing (11), a first Hall IC (22) and a second Hall IC (23) that are installed at the operation housing (21) so as to correspond to the magnets (12, 13), and state determination means (35) for determining each of the open/close states of the display housing (11) and the operation housing (21) based on detection information from the Hall ICs (22, 23).</p> |
