[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a wireless device including a wireless device such as a transceiver and an accessory device connected to the wireless device via a connection cable.

[0002]

[Prior art and problems]

 In the past, specific low-power portable transceivers based on the Radio Law were required to have an integrated antenna, and the transmission power of radio waves was also limited.

For this reason, for example, when communication is performed from a moving vehicle to another moving vehicle, the communicable distance becomes extremely short, and communication on a highway or in an urban area is performed. However, in order to increase the communication distance, transceiver users often lean out from the window and communicate with each other, which poses a problem.

The present invention solves the problems existing in the prior art, and provides a wireless device that can dramatically increase the communicable distance from the interior of an automobile or the like and contribute to safety. With the goal.

[0005]

[Means for Solving the Problems]

 In the present invention, when the wireless device 1 including the wireless device 2 and the auxiliary device 4 such as the external handset 4a and the data processing device 4b which is connected to the wireless device 2 through the connection cables 3a and 3b is configured, It is characterized in that the wireless device 2 is provided with a fixing means 5, for example, magnets 5a and 5b, which can be attached to and detached from an outdoor surface F of an automobile body or the like.

It is desirable that the connection cables 3 a and 3 b or the accessory device 4 be provided with power supply connectors 6 a and 6 b capable of supplying power to the wireless device 2 and the accessory device 4. Further, it is desirable that the wireless device 2 is provided with an antenna 7 whose angle can be changed, and a water-proof case 8 that covers the wireless device 2.

[0007]

[Action]

 According to the wireless device 1 of the present invention, when the wireless device 2 is used indoors such as an automobile, for example, when communicating with other wireless devices or data processing units outside the room, only the wireless device 2 is used. Is taken out of the room and fixed to the outside surface F of the automobile body or the like by magnets 5a and 5b (fixing means). At this time, if the antenna 7 provided in the wireless device 2 is erected, the sensitivity is further enhanced, and if the wireless device 2 is housed in the waterproof case 8 if necessary, the wireless device 2 is protected from rainwater even in rainy weather. ..

Further, the accessory device 4 is connected to the outdoor radio 2 via the connection cables 3a and 3b. As a result, since the accessory 4 can be used indoors and the antenna 7 is arranged outdoors, the communicable distance is dramatically expanded even when used in the interior of a vehicle.

【Example】

 Next, preferred embodiments according to the present invention will be described in detail with reference to the drawings.

First, the configuration of the wireless device 1 according to the present invention will be described with reference to FIGS. 1 and 2.

The wireless device 1 includes a wireless device 2 and an accessory device 4. The wireless device 2 is, for example, a specific low power type transceiver, and has a function of transmitting or receiving to or from another transceiver or a data processing unit. The wireless device 2 is provided with a display unit 11, operation buttons 12, a receiver unit 13, an antenna 7, and the like on the outside thereof, and also incorporates various functional circuits, a battery, and the like. In this case, the antenna 7 is rotatably attached to the body of the wireless device 2 so that the angle can be changed.

Further, a fixing means 5, that is, a pair of spaced magnets (permanent magnets) 5 a and 5 b are provided on the back surface of the wireless device 2, and a connection cable to be described later is connected to a side surface of the wireless device 2. The connector parts 14 and 15 are provided.

Furthermore, a waterproof case 8 capable of accommodating the wireless device 2 therein is prepared. As shown in FIG. 2, the waterproof case 8 can be formed, for example, in the shape of a bag from a flexible transparent material, and the entrance 8x is provided at one end and the exposure opening 8y of the antenna 7 is provided at the other end. You can

On the other hand, as the auxiliary equipment (including peripheral equipment) 4, an external handset 4a and a data processing equipment 4b such as a portable personal computer can be used. In this case, the handset 4a can be connected to the connector unit 14 via the connection cable (connection cord) 3a, and the data processing device 4b can be connected to the connector unit 15 via the connection cable (RS232C or the like) 3b.

The connection cables 3 a and 3 b may be provided with power supply connectors 6 a and 6 b capable of supplying power to the accessory device 4 and the wireless device 2. As a result, even if the battery runs out during use, power can be supplied from the power supply unit of the cigarette lighter provided in the vehicle, the auxiliary battery, etc. without removing the wireless device 2 from the outdoor surface F. The power supply connector may be provided in the accessory device 4.

Next, the usage and function of the wireless device 1 according to the present invention will be described with reference to FIGS.

First, when communicating (transmitting / receiving) with another wireless device or the like outside the vehicle interior in the interior of the vehicle C (FIG. 3), only the wireless device 2 is taken out of the vehicle interior and the magnets 5a and 5b are attached. Fix it to the exterior surface (roof surface) F of the car body. At this time, if the antenna 7 is erected, the sensitivity can be further improved, and if the radio 2 is housed in the waterproof case 8 if necessary, the radio 2 can be protected from rainwater even in the rain. On the other hand, the connection cable 3a is connected to the connector portion 14 of the wireless device 2 (see FIG. 1). This allows the external handset 4a to be used in the passenger compartment. Therefore, even if the antenna 7 is used in the vehicle interior, the antenna 7 is arranged outside the vehicle interior, so that the communicable distance is dramatically expanded, and communication between vehicles on a highway can be favorably performed.

On the other hand, as shown in FIG. 3, when data communication is performed in the interior of the automobile C with the data processing unit 21 provided in the vending machine S outside the automobile, the exterior surface F of the automobile body is The connector unit 15 of the wireless device 2 fixed to the above and the data processing device (portable personal computer) 4b placed in the vehicle compartment are connected by the connection cable 3b. As a result, the data processing device 4b can be operated in the passenger compartment, predetermined command information can be transmitted to the data processing unit 21 via the wireless device 2, and the sales information of the vending machine S and the like can be sent from the data processing unit 21. It can be received, and for example, it can be surely transmitted / received from a place away from the vending machine S due to road conditions or the like. Therefore, the communicable distance is dramatically expanded similarly to the communication between the wireless devices described above. In FIG. 3, reference numeral 22 indicates an antenna provided in the vending machine S.

Although the embodiments have been described in detail above, the present invention is not limited to such embodiments. For example, although a case where a magnet is used as the fixing means is shown, other fixing means such as a suction plate may be used. Further, although the automobile body is exemplified as the outdoor surface, it may be another outdoor surface such as an outer wall surface of a building. In addition, the detailed configuration, shape, material and the like can be arbitrarily changed without departing from the scope of the present invention.
