Abstract
First display (4) comprising a liquid crystal display is provided on the external surface of the first case body (1). In the near proximity of the first display (4), a non-voice radio communications service start button (5), scroll buttons (6a), (6b), and a selection/decision button (7) are provided. On the internal surface of the first case body (1), the second display 8, on the side of which is provided an antenna 9 retractable slantwise, is provided. In the first case body (1) is embedded a magnet (18) and in the second case body (2) is embedded a lead switch (19). When the main unit is folded to bring the magnet (18) in close proximity to the lead switch (19), the lead switch is turned ON. When the main unit is unfolded to place the magnet (18) apart from the lead switch (19), the lead switch is turned OFF. This allows detection of folding/unfolding of the case body.
