<p>PURPOSE: A slide type mobile phone is provided so that a button portion slides and a screen of a display unit is changed from a small screen to an expanding screen. CONSTITUTION: A body(100) has a display unit(110) which is classified as a large screen formed over the half of a mobile phone size and a small screen formed about 1/3 size of the large screen. A button portion(200), which is combined with the body(100) at its lower surface, covers the body(100) so that the button portion(200) slides on the display unit(110) of the body(100). The button portion(200) has an extending portion(201), which is extended at both sides, at its upper end. When the button portion(200) is not used, the display unit(110) is formed as the small screen by the length of the extending portion(201). When the button portion(200) is used, the extending portion(201) is maximally opened and the display unit(110) is formed as the large screen.</p> |
