Abstract:
1. An apparatus for detecting an opening and a closing of a slide-type mobile communication terminal having a main body and a sub-body mounted on said main body, said sub-body being movable relative to said main body in a sliding manner between the open position where said sub-body slides up so as to expose a part of said main body and the closed position where said sub-body slides down to completely cover said main body, comprising: a signal generating element provided in said sub-body for generating a predetermined signal; a first and a second signal sensor provided at two positions separated by a predetermined interval in said main body so as to face said signal generating element respectively when said sub-body slides up and down relative to said main body, said first and second signal sensors detecting said predetermined signal; and a control unit for performing corresponding functions according to the opening and closing operations of said mobile communication terminal represented by different signals generated by said first and second signal sensors, the control unit detecting a relative position of the sub-body and the main body in one of a first position, a second position, and a transition position, the first position corresponding to the sub-body fully slid up, the second position corresponding to the sub-body fully slid down, and the transition position being between the first and second positions.
