Abstract
Abstract A portable telephone with a fundamental structure consisting of a first housing with a built-in receiver and a second housing with a built-in transmitter which are connected around a hinge section in a rotatable manner, which further has biasing means for biasing the first housing and the second housing for their unfolding, attaching means for attaching the first housing and the second housing and detaching means for detaching the attached housings. 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 Analysis
Total Claims: 17
Claim 1
Independent Claim
179 words
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
Independent Claim
179 words
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 3
Dependent Claim
45 words
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 4
Dependent Claim
20 words
The apparatus as claimed in claim 1, wherein the detaching means and the antenna-detaching means operate in an interlocked manner.
Claim 5
Dependent Claim
22 words
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 6
Dependent Claim

Claim 8
Dependent Claim
58 words
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 9
Dependent Claim
44 words
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 10
Dependent Claim
