Abstract

A portable wireless communication apparatus of new type is provided. The apparatus is composed of a handset type substantially parallelopiped body which is to be used in combination with a battery pack in a portable mode and a support tray installed in a passenger car room for hand-free use. The top surface of the body is provided with a key operating section, a display section and a speaker. All of them are in the user'"'"'s sight while the apparatus is being used in the hand-free mode. In the portable mode, on the other hand, all the user has to do is only take up the apparatus away from the tray after the key board operation, hold the receiving section against the ear and talk into the transmitting section without changing the grip.

Claims

1. A portable wireless communication apparatus comprising

a substantially rectangular parallelopiped body having a top surface and a bottom surface wherein said top surface is provided with a key operating section, a display section and a speaker, whereas said bottom surface is provided with a transmitter section and a receiver section;

a collapsible antenna and a connector mounted to perspective longitudinal end surfaces of said body;

said bottom surface of the body having a battery pack seat between said transmitter section and said receiver section;

a battery pack removably attached to said battery pack seat; and

said battery pack seat being structured to engage an automobile passenger compartment support table when not attached to said battery pack and being powered from said support table.

2. A portable wireless communication apparatus according to claim 1, wherein said receiver section rises from said bottom surface to protrude beyond the attached battery pack.

3. A portable wireless communication apparatus according to claim 1, wherein said support table has a support surface for releasably engaging said battery pack seat of said body.

4. A portable wireless communication apparatus comprising:

a substantially rectangular parallelopiped body having a top surface annd a bottom surface wherein said top surface is provided with a key operation section, a display section and a speaker for hand-free communication, and said bottom surface is provided with a transmitter section and a receiver section at opposite ends thereof and a battery pack seat positioned therebetween;

a collapsible antenna and a connector provided in respective longitudinal end surfaces of said parallelopiped body;

a battery pack releasably attached to said battery pack seat;

said parallelopiped body connected to a support table, said support table mounted in a vehicle, said support table further connectable to a plurality of devices including a power supply of the vehicle, an external antenna of the vehicle and an external hand-free microphone, whereby said portable wireless communication apparatus is operable as a vehicle-mounting type communication apparatus acquiring electric power from said vehicle and automatically switching from said collapsible antenna thereof to said external antenna.

5. A portable wireless communication apparatus as claimed in claim 4, wherein said parallelopiped body thereof and said support table are connected through a curl cord.

6. A portable wireless communication apparatus as claimed in claim 4, wherein said receiver section rises from said bottom surface in such a manner that it protrudes beyond said attached battery pack.

7. A portable wireless communication apparatus as claimed in claim 4, wherein said support table is further connected with a battery charging adaptor for charging said battery pack.

8. A portable wireless communication apparatus as claimed in claim 4, wherein said support table is connected to said power supply, to said-external antenna and to said external hand-free microphone thereby to operate as a vehicle-mounted communication apparatus receiving electric power from said power supply of the vehicle and automatically switching from said collapsible antenna thereof to said external antenna of the vehicle.

9. A portable wireless communication apparatus as claimed in claim 4, wherein said parallelopiped body further includes release means for releasably engaging said battery pack.

10. A portable wireless communication apparatus as claimed in claim 9, wherein said release means comprises a slit-and-projection arrangement on said parallelopiped body and on said battery pack, together with a release lever for retracting said projection thereby to release said battery pack.

11. A portable wireless communication apparatus as claimed in claim 10, wherein one of a slit and a projection is provided on said parallelopiped body and the other of said slit and said projection is provided on said battery pack;

and wherein said support table also includes the other of said slit and said projection, and wherein said release laver is provided for withdrawing said projection thereby to engage and release said battery pack to said battery pack seat and to engage and release said support table from said battery pack seat.

12. A portable wireless communication apparatus as claimed in claim 4, further including vehicle antenna connecting means for connecting said support table to said external antenna of the vehicle and wherein said parallelopiped body and said support table are connected by further connecting means including therein means for connecting the parallelopiped body through said support table to said external antenna of the vehicle.

13. A portable wireless communication apparatus comprising:

a substantially rectangular parallelopiped body having a top surface and a bottom surface wherein said top surface is provided with a key operating section, a display section and a speaker for hand-free communication, and said bottom surface is provided with a transmitter section and a receiver section at opposite ends thereof and a battery pack seat positioned therebetween;

a collapsible antenna and a connector provided in respective longitudinal end surfaces of said parallelopiped body;

a battery pack releasably attached to said battery pack seat;

said parallelopiped body connected to a support table, said support table mounted in a vehicle, said support table further connectable to a plurality of devices including a power supply of the vehicle, an external antenna of the vehicle and an external hand-free microphone, whereby said portable wireless communication apparatus is operable as a vehicle-mounting type communication apparatus acquiring electric power from said vehicle and automatically switching from said collapsible antenna thereof to said external antenna;

wherein said support table further includes means for accepting said battery pack seat.

14. A portable wireless communication apparatus as claimed in claim 13, wherein said parallelopiped body thereof and said support table for accepting said battery pack seat are connected through a curl cord.
