Abstract

A portable radio apparatus includes an antenna, a transceiver body having a receiver on an upper portion thereof and a transmitter on a lower portion thereof, and a mechanism for drawing out the receiver from the body to a side close to an ear of an operator. Also, in a portable radio apparatus including a transceiver body, a receiver provided in the body and an antenna provided on the body, the transceiver body is divided into a first unit including at least one receiver and a second unit coupled with the first unit, and the antenna is projected from the second unit.

Claims

1. A portable radio apparatus, comprising:

a body;

an antenna provided at an upper portion of said body;

an earpiece hingedly coupled to said body;

a mouthpiece provided at a lower portion of said body,

wherein said earpiece is movable between a first position wherein said earpiece is substantially flush with a front of said body, and a second position wherein said earpiece is angularly rotated away from a top of said antenna towards said mouthpiece, so that during normal use with the earpiece positioned in the vicinity of an operator'"'"'s ear, a head of said operator will be positioned farther from said antenna top when said earpiece is in said second position than when said earpiece is in said first position.

2. A portable radio apparatus according to claim 1, wherein said earpiece is hingedly coupled to said body at approximately the middle of said body.

3. A portable radio apparatus according to claim 1, wherein said earpiece is hingedly coupled to said body on opposing sides of said body.

4. A portable radio apparatus according to claim 1, wherein said portable radio apparatus is in a non-call state when said earpiece is in said first position, and said portable radio apparatus is in a call state when said earpiece is in said second position.

5. A portable radio apparatus according to claim 1, wherein said antenna is retractable into said body.

6. A portable radio apparatus according to claim 1, wherein a surface of said earpiece and a surface of said body comprising said mouthpiece form a plane-like surface when said earpiece is in said first position.

7. A portable radio apparatus, comprising:

a body;

an antenna provided at an upper portion of said body;

an earpiece hingedly coupled to said body and retractable into said body;

a mouthpiece provided at a lower portion of said body,

wherein said earpiece is movable between a first position wherein said earpiece is substantially flush with a front of said body, and a second position wherein said earpiece is angularly rotated away from a top of said antenna towards said mouthpiece, so that during normal use with the earpiece positioned in the vicinity of an operator'"'"'s ear, a head of said operator will be positioned farther from said antenna top when said earpiece is in said second position than when said earpiece is in said first position.

8. A portable radio apparatus according to claim 7, wherein said portable radio apparatus is in a non-call state when earpiece is in said first position, and said portable radio apparatus is in a call state when said earpiece is in said second position.

9. A portable radio apparatus according to claim 7, wherein said antenna is retractable into said body.

10. A portable radio apparatus according to claim 7, wherein a surface of said earpiece and a surface of said body comprising said mouthpiece form a plane-like surface when said earpiece is in said first position.
