  • Publication number: 20060120029
    Abstract: A portable terminal includes a main housing, a sliding housing coupled to the main housing in such a manner that it can slide to expose or hide a part of a surface of the main housing, a keypad module positioned on the main housing and adapted to be exposed or hidden as the sliding housing moves, and a driving means positioned on the main housing to cause the keypad module, when exposed by the movement of the sliding housing, to protrude from a surface of the main housing. The sliding movement of the sliding housing is converted into up-and-down movement of the keypad module to overcome the difference in level among the upper surface of the sliding housing, the display device, and the keypad for convenient key input.

  • Patent number: 6091815
    Abstract: A flip cover of a portable telephone apparatus, in which a flip cover includes a two stage extension so as to prevent transmitted voice from being dispersed and to prevent any noise from occurring when transmitting and receiving speech (voice). The flip cover includes an upper flip, a lower flip fixed to an inner side of the upper flip, and an inner flip slidably mounted to the upper and lower flip. A guide rib formed in the upper flip and a slide groove formed in the lower flip facilitate the sliding motion. A fixing projection provided on an upper side of the lower flip and upper and lower fixing grooves on the inner flip are adapted to be fixably fitted into the fixing projection. A guide projection formed at both sides of the front end of the inner flip is adapted to be fitted into the slide groove of the lower flip and guided therein.
