An antenna is attached to the second housing in a rotatable manner. The first housing and the second housing are folded when the telephone is not in use. For reception or transmission, the attached first housing and second housing and the attached antenna are detached to unfold the telephone to set a usable state by a one-touch operation with a slide button. ## Claims ### Claim 1 An apparatus for unfolding and activating a portable telephone, which comprises: a first housing having at least a built in receiver; a second housing having at least a transmitter, an antenna anchored so as to be rotatable around an antenna hinge section, antenna-biasing means for biasing the antenna for extending thereof, antenna-attaching means for attaching the antenna and antenna-detaching means for detaching the attached antenna; a hinge section for rotatably connecting the first and second housing such that the housings are capable of attaining a folded position; a biasing means for biasing the first housing and the second housing into an unfolded position; a first magnet positioned on the first housing; a second magnet positioned on the second housing, such that one of the poles of the first magnet faces the opposite pole of the second magnet for magnetically attracting one magnet to the other when in the folded position; a detaching means for detaching the attached first housing and second housing; and a hook switch positioned in the second housing for activating the electronic operation of the telephone. ### Claim 2 (depends on 1) The apparatus as claimed in claim 1, wherein the detaching means is a means for moving the first magnet positioned on the first housing and/or the second magnet positioned on the second housing to increase the spacing between the first magnet and the second magnet. ### Claim 3 (depends on 1) The apparatus as claimed in claim 1, wherein the detaching means and the antenna-detaching means operate in an interlocked manner. ### Claim 4 (depends on 1) The apparatus as claimed in claim 1, wherein the detaching means, the antenna-detaching means and the hook-switch operate in an interlocked manner. ### Claim 5 (depends on 1) The apparatus as claimed in claim 1, wherein the biasing means is a spring placed at the hinge section. ### Claim 6 (depends on 1, 2) The apparatus as claimed in claim 1 or 2, wherein either magnet of the first magnet and second magnet is replaced by a metal which attracts the other magnet. ### Claim 7 (depends on 1) The apparatus as claimed in claim 1, wherein the antenna-attaching means comprises a third magnet positioned on the antenna and a fourth magnet positioned on the second housing, the magnets being positioned such that one of the poles of the third magnet faces the opposite pole of the fourth magnet when the antenna is in its attached position. ### Claim 8 (depends on 1) The apparatus as claimed in claim 1, wherein the antenna-detaching means is a means for moving the third magnet placed on the antenna and/or the fourth magnet positioned on the second housing to increase the spacing between the third magnet and the fourth magnet. ### Claim 9 (depends on 1) The apparatus as claimed in claim 1, wherein the antenna-biasing means is a spring positioned at the antenna hinge section. ### Claim 10 (depends on 7, 8) The apparatus as claimed in claims 7 or 8, wherein either magnet of the third magnet and the fourth magnet is replaced by a metal which attracts the other magnet. ### Claim 11 (depends on 2) The apparatus as claimed in claim 2, wherein the detaching means comprises a connecting member which connects to the second magnet and a slide button positioned on the connecting member. ### Claim 12 (depends on 7) The apparatus as claimed in claim 7, wherein the antenna-detaching means comprises a connecting member which connects to the fourth magnet and a slide button positioned on the connecting member. ### Claim 13 (depends on 3, 11, 12) The apparatus as claimed in claims 3, 11 or 12, wherein the detaching means and the antenna-detaching means comprise the connecting member which connects to the second magnet or the fourth magnet and the slide button positioned on the connecting member. ### Claim 14 (depends on 13) The apparatus as claimed in claim 13, further comprising a switch positioned near the connecting member at a given distance for activating the electronic operation of the telephone when pressed by the connecting number. ### Claim 15 (depends on 11, 12) The apparatus as claimed in claims 11, 12, or 14 wherein the connecting member further comprises a spring for biasing the connecting member and slide button into their home positions. ### Claim 16 (depends on 13) The apparatus as claimed in claim 13, wherein the connecting member further comprises a spring for biasing the connecting member and slide button into their home positions.
