Abstract
Abstract A main body of a portable radio apparatus is split into an upper box and a lower box, and the upper box is connected to the upper part of the lower box to be rotatable about a hinge section. An antenna is similarly connected to be rotatable on the hinge section. When the lower body is swung open, the antenna is also swung simultaneously. As the antenna can be further swung, the distance between the head of the user and the antenna can be maximized during communication.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
178 words
A portable radio apparatus comprising: a first body including at least a receiving section; a second body; a hinge section for connecting said first body and said second body such that said first body can be rotated with respect to said second body from a closed position to an open position; and an antenna rotatably installed on said hinge section, wherein said hinge section comprises: a first hinge portion integral to said second body; a second hinge portion integral to said first body and being rotatably coupled with said first hinge portion; a third hinge portion integral to said first body; a fourth hinge portion integral to said second body and being rotatably coupled to said third hinge portion; a fifth hinge portion integral to said antenna, and coupling means for mechanically coupling said fifth hinge portion with one of said third and fourth hinge portions; wherein said antenna is rotatable when said first and second bodies are closed, and wherein said antenna rotates in response to rotation of a corresponding one of said first and second bodies.
Claim 2
Dependent Claim
178 words
A portable radio apparatus comprising: a first body including at least a receiving section; a second body; a hinge section for connecting said first body and said second body such that said first body can be rotated with respect to said second body from a closed position to an open position; and an antenna rotatably installed on said hinge section, wherein said hinge section comprises: a first hinge portion integral to said second body; a second hinge portion integral to said first body and being rotatably coupled with said first hinge portion; a third hinge portion integral to said first body; a fourth hinge portion integral to said second body and being rotatably coupled to said third hinge portion; a fifth hinge portion integral to said antenna, and coupling means for mechanically coupling said fifth hinge portion with one of said third and fourth hinge portions; wherein said antenna is rotatable when said first and second bodies are closed, and wherein said antenna rotates in response to rotation of a corresponding one of said first and second bodies.
Claim 3
Dependent Claim
19 words
The apparatus as claimed in claim 1, wherein said antenna is secured at one end of said hinge section.
Claim 4
Dependent Claim
27 words
The apparatus as claimed in claim 2, wherein said first body includes a display section and said second body includes a keyboard section and a transmitting section.
Claim 5
Dependent Claim
19 words
The apparatus as claimed in claim 1, wherein said antenna is secured at both ends of said hinge section.
Claim 6
Dependent Claim
58 words
The apparatus as claimed in claim 1, wherein said coupling means comprises: a pin provided in one of said third and fourth hinge portions and extending from an end face thereof; and a groove formed in an opposing end face of said fifth hinge portion in which said pin is received, said groove extending over a predetermined angle.
Claim 7
Dependent Claim
36 words
The apparatus as claimed in claim 5, wherein one end of said groove is pushed by said pin when said corresponding one body is opened, so that said antenna is rotated with said corresponding one body.
Claim 8
Dependent Claim
37 words
The apparatus as claimed in claim 6, wherein an opposite end of said groove is pushed by said pin when said corresponding one body is closed, so that said antenna is rotated with said corresponding one body.
Claim 9
Dependent Claim
40 words
The apparatus as claimed in claim 7, wherein said antenna is further rotatable by said predetermined angle until said pin abuts against one of said ends of said groove in a condition when said first and second bodies are fixed.
