Abstract

A receiver includes a first case to which an integrated circuit controlling component of the receiver is mounted, and a second case pivotally mounted to the first case and having an antenna mounted thereto. The integrated circuit and the antenna are thus mounted in different cases so as to be separated from each other, and the receiver receives a radio wave with less noise from the integrated circuit. An LCD is mounted to one of the cases such that the LCD is interposed between the antenna and integrated circuit, to substantially shield the antenna from the integrated circuit, when the cases are closed together.

Claims

1. A portable radio apparatus comprising:

a first case;

a second case pivotably mounted to said first case;

a CPU (Central Processing Unit) for controlling components of the apparatus, said CPU being mounted to one of the first and second cases;

an antenna for receiving a radio wave, said antenna being mounted exclusively to another of the first and second cases; and

an LCD (Liquid Crystal Display) for displaying information, said LCD being mounted to one of said first case and said second case such that said LCD is interposed between said antenna and said CPU, to substantially shield the antenna from the CPU, when said first case is pivoted to a closed position relative to said second case, said first case being located over said second case in said closed position.

2. The portable radio apparatus as recited in claim 1, wherein said second case is electrically connected to said first case.

3. The portable radio apparatus as recited in claim 1, wherein said second case is joined to said first case by a hinge.

4. The portable radio apparatus as recited in claim 1, wherein said LCD includes a display section which causes display of information under control of the CPU.

5. The portable radio apparatus as recited in claim 1, wherein said LCD is mounted to said first case, said LCD overlapping with said CPU in a thickness direction of the first case.

6. The portable radio apparatus as recited in claim 1, further comprising:

an RF (Radio Frequency) circuit mounted to said second case, said RF circuit being coupled to said antenna to receive a signal from said antenna.

7. The portable radio apparatus as recited in claim 1, wherein said first case is an apparatus core and said second case is a lid assembly having a thickness less than that of the apparatus core.

8. The portable radio apparatus as recited in claim 7, wherein said LCD is mounted to said lid assembly.

9. The portable radio apparatus as recited in claim 8, further comprising a sheet key unit, the sheet key unit being mounted to a surface of said apparatus core which is opposite to the LCD when the apparatus core and the lid assembly are closed.

10. The portable radio apparatus as recited in claim 1, wherein said second case is an apparatus core and said first case is a lid assembly having a thickness less than that of the apparatus core.

11. The portable radio apparatus as recited in claim 10, wherein said LCD is mounted to said lid assembly.

12. The portable radio apparatus as recited in claim 10, further comprising a sheet key unit, the sheet key unit being mounted to a surface of said apparatus core which is opposite to the LCD when the apparatus core and the lid assembly are closed.

13. The portable radio apparatus as recited in claim 1, wherein said LCD is mounted to said first case.

14. The portable radio apparatus as recited in claim 1, wherein said LCD is mounted to said second case.
