Abstract

A portable radio device includes a radio device main body, a man-machine interface unit, a first interface unit, a fixing adaptor, and a cord. The radio device main body has a radio unit for transmitting/receiving a radio speech signal and a control unit for controlling a signal transmitting/receiving operation of the radio unit. The man-machine interface unit has a telephone transmitter unit and a telephone receiver unit, which are used for speech communication, and is detachably coupled to the radio device main body. The first interface unit electrically connects the radio device main body to the man-machine interface unit in a coupled state. The radio device main body is detachably mounted on the fixing adaptor. The fixing adaptor supplies power to the radio device main body in a mounted state of the radio device main body. The cord is detachably connected to the man-machine interface unit and electrically connects the man-machine interface unit to the radio device main body through the fixing adaptor.

Claims

1. A portable radio device comprising:

a radio device main body having a radio unit for transmitting/receiving a radio speech signal and a control unit for controlling a signal transmitting/receiving operation of said radio unit;

a man-machine interface unit having a telephone transmitter unit and a telephone receiver unit, which are used for speech communication, and detachably coupled to said radio device main body;

a first interface for electrically connecting said radio device main body to said man-machine interface unit in a coupled state;

a fixing adaptor, on which said radio device main body is detachably mounted, for supplying power to said radio device main body in a mounted state of said radio device main body; and

a cord, detachably connected to said man-machine interface unit, for electrically connecting said man-machine interface unit to said radio device main body through said fixing adaptor when said radio device main body is mounted on said fixing adaptor.

2. A device according to claim 1, further comprising a switch for electrically disconnecting said radio device main body from said man-machine interface unit when said radio device main body is mounted on said fixing adaptor, a second interface for electrically connecting said fixing adaptor to said man-machine interface unit when said radio device main body is mounted on said fixing adaptor, and a third interface for electrically connecting said man-machine interface unit to said cord connected to said fixing adaptor.

3. A device according to claim 2, wherein said switch is arranged in said radio device main body, and said control unit of said radio device main body detects that the second and third interfaces are connected, thereby controlling a disconnecting operation of said switch.

4. A device according to claim 2, wherein said fixing adaptor is connected to an external battery and an external antenna, and when said radio device main body is mounted on said fixing adaptor, said fixing adaptor supplies power from said external battery to said man-machine interface unit through said cord and said third interface, supplies power from said external battery to said radio device main body through said second interface, and connects said radio device main body to said external antenna.

5. A device according to claim 4, wherein said fixing adaptor is arranged in an automobile, said external antenna is constituted by a mobile antenna arranged on the automobile, and said external battery is constituted by a mobile battery mounted in the automobile.

6. A device according to claim 4, wherein a speech signal from/to said telephone receiver unit of said man-machine interface unit/said telephone transmitter unit is input to/output from said radio device main body through said third interface, said cord, said fixing adaptor, and said second interface, and said radio unit of said radio device main body performs a conversion operation between a high-frequency signal and a speech signal and an input/output operation of a high-frequency signal with said external antenna through said second interface and said fixing adaptor.

7. A device according to claim 2, wherein said man-machine interface unit having said third interface set in a disconnected state is coupled to said radio device main body having said second interface set in a disconnected state when said first interface is set in a connected state, thereby constituting a portable radio telephone device.

8. A device according to claim 2, wherein said first, second, and third interfaces include detachable connector members, respectively.

9. A portable radio device comprising:

a radio device main body having a radio unit for transmitting/receiving a radio speech signal and a control unit for controlling a signal transmitting/receiving operation of said radio unit;

a man-machine interface unit having a telephone transmitter unit and a telephone receiver unit, which are used for speech communication, and detachably coupled to said radio device main body; and

a fixing adaptor, on which said radio device main body is detachably mounted, for supplying power to said radio device main body in a mounted state of said radio device main body,

wherein, when said radio device main body is mounted on said fixing adaptor, said man-machine interface unit is electrically connected to said radio device main body through said adaptor, and, when said radio device main body is not mounted on said adaptor, said man-machine interface unit is coupled to said radio device main body, thereby directly, electrically connecting said man-machine interface unit to said radio device main body.

10. A portable radio device comprising:

a radio device main body having a radio unit for transmitting/receiving a radio speech signal and a control unit for controlling a signal transmitting/receiving operation of said radio unit;

a man-machine interface unit having a telephone transmitter unit and a telephone receiver unit, which are used for speech communication, and detachably coupled to said radio device main body;

a first interface for electrically connecting said radio device main body to said man-machine interface unit in a coupled state;

a fixing adaptor, which is arranged in an automobile and connected to a mobile battery and a mobile antenna, and on which said radio device main body is detachably mounted, for supplying power to said radio device main body in a mounted state of said radio device main body;

a cord, detachably connected to said man-machine interface unit, for electrically connecting said man-machine interface unit to said radio device main body through said fixing adaptor;

a switch for electrically disconnecting said radio device main body from said man-machine interface unit when said radio device main body is mounted on said fixing adaptor;

a second interface for electrically connecting said fixing adaptor to said man-machine interface unit when said radio device main body is mounted on said fixing adaptor; and

a third interface for electrically connecting said man-machine interface unit to said cord connected to said fixing adaptor,

wherein, when said radio device main body is mounted on said fixing adaptor, said fixing adaptor supplies power from said mobile battery to said man-machine interface unit through said cord and said third interface, supplies power from said mobile battery to said radio device main body through said second interface, and connects said radio device main body to said mobile antenna.
