DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door-to-door radio receiver for disaster prevention used as part of disaster management.

[0002]

2. Description of the Related Art FIG. 3 is a block diagram showing the configuration of a conventional example of this type of apparatus. The radio signal transmitted from the base station 1 is received by the antenna of the door-to-door receiver, and is amplified by the high-frequency amplifier 2. The selective calling (receiving) unit 3 determines whether or not to receive the signal, and if it is determined that the signal is to be received, sends a signal (voice) to the low-frequency amplifying unit 4 to drive the internal speaker or the external speaker 5. The power supply unit 6 supplies power to each unit. The operation unit 7 includes a power switch, a volume control, and a power lamp.

When the signal is other than a voice signal (FAX),
A signal is output to the FAX terminal 8 after being identified by the selective calling (receiving) unit 3. When a voice signal is to be recorded, it is identified by the selective calling (receiving) unit 3 and output to the recording terminal 9.

[0004]

However, in the conventional door-to-door receiving apparatus, the external appearance of the main body of the receiver is very large, and the receiver has a considerable weight. There is.

[0005] Furthermore, since it is fixed by using the wall of each house, there is an inconvenience that if it becomes necessary to remove it, it cannot be easily done.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a portable disaster-prevention radio that can be easily attached to and detached from an apparatus main body as a small-sized portable reception unit that is convenient for carrying.
It is an object of the present invention to provide a door-to-door wireless receiving device for disaster prevention which can be removed from the portable radio and carried in an emergency.

[0007]

A door-to-door radio receiving apparatus for disaster prevention according to the present invention has an apparatus main body attached to a door, and is carried by a radio paging receiver or a portable radio which can be heard at an audible frequency. The receiving unit is detachable. For example, when the portable receiving unit to be detached is a portable radio, the portable radio is automatically electrically connected when the portable radio is attached to the apparatus main body. In an emergency, only the portable radio can be detached from the apparatus main body to receive a single signal. .

In this case, a facsimile,
Each terminal for recording and outputting video can be provided. The apparatus main body has a main body antenna and a main body speaker, and the portable information receiving section, which is equipped with the radio information, processes the radio information received by the main body antenna, amplifies the information, and amplifies the sound by the main body speaker.

On the other hand, the portable radio has an internal antenna which is switched from a main body antenna when the portable radio is detached from the main body of the apparatus, and has an internal speaker for amplifying radio information received by the internal antenna and loudspeaking. I have.

[0010] The portable radio is provided with a display unit for displaying radio information received by a main body antenna or an internal antenna.

The internal speaker built into the portable radio is minimized for power saving. Also, NHK
It is possible to listen to about 1 channel (channel) station of the broadcast, but it is preferentially switched when administrative notification is received. Furthermore, if the portable radio is used only for disaster prevention (emergency use), a selective receiving unit can be incorporated in the apparatus main body so that all can be received. When the government notice is received, the priority is switched to listen to the broadcast in the local area.

[0012]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, an embodiment of a door-to-door radio receiving apparatus for disaster prevention according to the present invention will be described in detail with reference to the drawings.

As shown in FIG. 1, in a door-to-door radio receiving apparatus according to the present embodiment, a portable radio 20 for receiving disaster prevention information as a portable receiving section according to the present invention is provided inside a main body 10 of the present invention.
Alternatively, a wireless paging receiver (selective paging receiver) of a portable terminal in place of this is simply and detachably accommodated.
This portable radio 20 is slidably attached to the device body 10 so that it can be carried quickly in the event of a disaster,
Or it can be easily removed from the front of the main unit with one touch.

When the portable radio 20 is used by being mounted on the apparatus main body 10, when the portable radio 20 is inserted and set, the portable radio 20 is automatically connected to the apparatus main body 10 by the connection terminal 11 at that position.

The radio wave of the information received by the main body antenna 12 is selected by a selective calling section provided in either the apparatus main body 10 or the portable radio 20, and its input signal is amplified by a power supply / amplifying section 13 to be amplified by a speaker. 14 can be sounded, or signals can be output to the FAX terminal 15, the recording terminal 16, the video output terminal 17, and the like.

On the other hand, as shown in FIG. 2, when the portable radio 20 is detached from the apparatus main body 10 and used alone, the connection terminal 21 is disconnected from the connection terminal 11 on the apparatus main body 10 side, and the portable radio is automatically turned off. Internal antenna 2 in 20
Switch to 2. When a broadcast arrives, the internal speaker 23
Alternatively, an earphone connected to the earphone terminal 24 sounds. Since the antenna of the portable radio 20 relieves the weak electric field, the external antenna 12 can also be used. Power /
A volume control switch 25 is provided, and is operated when the portable device is used by being removed from the device body 10. In addition, a display unit 26 including a liquid crystal display (LCD) is also provided to display necessary information.

The internal speaker 23 is set to the minimum necessary for power saving. The earphone terminal 24 is connected to the internal speaker 23
In order to prevent power loss due to the above, NHK broadcast channel 1ch station can be listened to, but when administrative notification is received, switching is performed preferentially.

As described above, the portable radio 2 of the present embodiment
0 indicates that only the receiving unit and the low frequency amplifying unit or the selective calling (receiving) unit is added. If used only for disaster prevention (emergency use), the selective receiving unit can be built in the apparatus main body 10 so that all can be received.

It should be noted that about one NHK broadcast channel can be received, and the priority is switched when receiving an administrative broadcast. In addition, when it is mounted on the apparatus main body 10, a signal can be output to a facsimile recording terminal.

[0020]

As described above, the door-to-door receiving apparatus of the present invention is most suitable for a disaster-prevention administrative radio system, and is normally used in each home at normal times. This is very useful since only the portable receiving unit such as a portable radio can be quickly and simply removed and carried alone.
