Abstract
A first display (4) comprising a liquid crystal display is provided on the outer surface of a first case body (1). In the near proximity of the first display (4), a call start button (5), a call release button (6), and a so-called navigation key (7) having an arrow key for scrolling in four directions and a center key for selecting and determining target information. A second display (8) is provided on the inner surface of the first case body (1). An antenna 9 is provided retractable slantwise on the side of the second case body (2). A magnet (18) is embedded in the first case body (1), and a lead switch 19 is embedded in the second case body (2). When the main body is folded to bring the magnet (18) in close proximity to the lead switch (19), the lead switch is turned ON. When the main body 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 main body. At the lower portion of the side where the antenna (9) is located, an earphone microphone jack 37 is provided.
