　この種の外部機器との接続には、ケーブルを用いる場合もあるが、近年では、Ｂｌｕｅｔｏｏｔｈ（登録商標）などの無線通信により接続を行うことも多くなっている。 In some cases, a cable is used for connection with this type of external device, but in recent years, connection is often performed by wireless communication such as Bluetooth (registered trademark).
　例えば、Ｂｌｕｅｔｏｏｔｈ（登録商標）で通信をする場合は、まず、パスキーなどの入力を行って接続可能機器とのペアリング（登録）を行い、その後にペアリングされた機器同士がリンク（接続）されて通信が行われる（例えば特許文献１を参照）。 For example, when communicating with Bluetooth (registered trademark), first, a pass key or the like is input to perform pairing (registration) with connectable devices, and then the paired devices are linked (connected). Communication is performed (see, for example, Patent Document 1).

　しかしながら、これまでの無線による外部機器の接続においては、ユーザが自らペアリング操作を行う必要があり、ユーザ自身が当該外部機器が接続可能であることを知らない場合は当然接続されることは無く、その外部機器を接続することで有効となる機能により得られる恩恵を受けることはできなかった。 However, in the connection of the external device so far, the user needs to perform the pairing operation himself, and if the user himself does not know that the external device can be connected, it is naturally not connected. It was not possible to receive the benefits gained by the functions enabled by connecting the external device.
　また、特許文献２のように、接続可能な外部機器のリストを作成して表示することも考えられるが、例えば、車載機器の場合、たまたま同乗した乗員や、車外にある機器を表示してしまう可能性があり、単に接続可能な外部機器のリストを作成して表示するだけでは不十分である。 In addition, as in Patent Document 2, it is conceivable to create and display a list of connectable external devices.

In the wireless communication apparatus according to the embodiment of the present invention, the external device detection unit that detects and identifies the external device detects the same external device a plurality of times with reference to the history information stored in the storage unit. In this case, since the notification means for notifying that the external device is connectable is notified, it is possible to eliminate the external device that is detected by accident in order to notify the same external device after detecting it multiple times. It is possible to detect a connectable external device owned by a person who frequently uses the device, such as a user, and prompt the connection.
　また、外部機器検出手段が、当該無線通信装置起動時に外部機器の検出および識別を行い、複数の起動回数中に所定回数以上同じ外部機器が検出された場合は報知手段に報知させてもよい。このようにすることにより、機器の起動時に外部機器を検出し識別して、履歴情報から複数の起動回数中に何度も検出される外部機器はユーザ等の所有する外部機器であると判定することができる。 In addition, the external device detection unit may detect and identify the external device when the wireless communication device is activated, and may notify the notification unit when the same external device is detected a predetermined number of times or more during a plurality of activation times.

The flowchart shown in FIG. 2 is executed when the car navigation device 1 is activated by the wireless connection control unit 4.
　まず、ステップＳ１０１において、登録済み無線機器接続処理を行いステップＳ１０２に進む。登録済み無線機器接続処理とは、既に登録されている無線機器（外部機器）がある場合、無線接続部３にその無線機器への接続を試みさせることである。 First, in step S101, a registered wireless device connection process is performed, and the process proceeds to step S102. The registered wireless device connection process is to cause the wireless connection unit 3 to try to connect to a wireless device when there is a wireless device (external device) that has already been registered.
　次に、ステップＳ１０２において、接続機器があるか否かを判断し、ある場合（ＹＥＳの場合）は終了し、無い場合（ＮＯの場合）はステップＳ１０３に進む。つまり、接続機器がある場合はステップＳ１０１による処理で当該無線機器が接続されているので、無線機器の登録促し動作は行わずに本フローチャートを終了し、接続機器が無い場合は以降の処理を行う。 Next, in step S102, it is determined whether there is a connected device. If there is a connected device (YES), the process ends. If not (NO), the process proceeds to step S103. In other words, if there is a connected device, the wireless device is connected in the process of step S101, so this flowchart is terminated without performing the wireless device registration prompting operation. If there is no connected device, the subsequent processing is performed. .
　次に、外部機器検出ステップ、記憶ステップとしてのステップＳ１０３において、周辺無線機器検索結果記録を行いステップＳ１０４に進む。周辺無線機器検索結果記録とは、無線機器を検索し発見された無線機器の情報を例えば記憶装置７などに記憶する処理である。Ｂｌｕｅｔｏｏｔｈ（登録商標）の場合、インクワイアリスキャンにより接続可能機器を検索することが可能であり、インクワイアリスキャンの結果を記憶する。また、記憶装置７にはインクワイアリスキャンを行う度にその結果を記憶するため、記憶装置７にはインクワイアリスキャンの履歴情報が蓄積される。また、発見された無線機器は、デバイスＩＤなどの各機器固有の番号等から識別し、同じデバイスＩＤの無線機器が既に記憶されている場合は、当該無線機器の発見回数を１加算して記憶する。したがって、この発見回数も履歴情報に含まれる。即ち、無線機器を検出し識別した結果を履歴情報として記憶している。 Next, in step S103 as an external device detection step and a storage step, the peripheral wireless device search result is recorded, and the process proceeds to step S104. The peripheral wireless device search result record is a process of searching for a wireless device and storing information on the discovered wireless device in, for example, the storage device 7. In the case of Bluetooth (registered trademark), connectable devices can be searched by an inquiry scan, and the result of the inquiry scan is stored. In addition, since the result of the inquiry scan is stored in the storage device 7, history information of the inquiry scan is accumulated in the storage device 7. The discovered wireless device is identified from a number unique to each device such as a device ID. If a wireless device with the same device ID is already stored, the number of times of discovery of the wireless device is incremented by 1 and stored. To do. Therefore, the number of times of discovery is also included in the history information. That is, the result of detecting and identifying the wireless device is stored as history information.
　次に、ステップＳ１０４において、ステップＳ１０３で検索した結果発見された周辺無線機器の数（発見機器数）を変数Ｍに設定するとともに、発見機器番号を示す変数Ｎを０にリセットしてステップＳ１０５に進む。この発見機器番号は、ステップＳ１０３において発見された無線機器各々に自動的に付与される番号であり、付与方法は発見順などで０から順に付与すればよい。 Next, in step S104, the number of peripheral wireless devices discovered as a result of the search in step S103 (the number of discovered devices) is set to the variable M, and the variable N indicating the discovered device number is reset to 0, and the process returns to step S105. move on. This discovered device number is a number automatically assigned to each wireless device discovered in step S103, and the assigning method may be assigned in order from 0 in the order of discovery.
　次に、ステップＳ１０５において、発見機器番号Ｎが発見機器数Ｍと同じ値か否かを判断し、同じ値である場合（ＹＥＳの場合）は終了し、同じ値で無い場合（ＮＯの場合）はステップＳ１０６に進む。本ステップで発見機器番号Ｎが発見機器数Ｍと同じ値である場合は、全ての発見機器に対して以降に説明する処理を行ったこととなるので終了する。 Next, in step S105, it is determined whether or not the discovered device number N is the same value as the discovered device number M. If it is the same value (in the case of YES), the process ends. If it is not the same value (in the case of NO). Advances to step S106. If the discovered device number N is the same value as the discovered device number M in this step, the processing described below has been performed for all discovered devices, and the process ends.
　次に、ステップＳ１０６において、発見機器番号Ｎが所定回数以上発見された記録があるか否かを判断し、ある場合（ＹＥＳの場合）はステップＳ１０８に進み、無い場合（ＮＯの場合）はステップＳ１０７に進む。本ステップでは、発見機器番号Ｎを付与された無線機器について、記憶装置７を参照して、過去に発見された記録が予め定めた所定回数以上（少なくとも２回以上）であった場合は記録ありと判断している。 Next, in step S106, it is determined whether or not there is a record in which the discovered device number N has been discovered a predetermined number of times or more. If there is a record (YES), the process proceeds to step S108; The process proceeds to S107. In this step, with respect to the wireless device to which the discovered device number N is assigned, with reference to the storage device 7, there is a record when a record found in the past is a predetermined number of times or more (at least twice or more) Judging.
　次に、ステップＳ１０７において、発見機器番号Ｎを１加算してステップＳ１０５に戻る。 Next, in step S107, the discovered device number N is incremented by 1, and the process returns to step S105.
　一方、報知ステップとしてのステップＳ１０８においては、ステップＳ１０６において、所定回数以上発見された無線機器名に対する登録促しの表示を行ってステップＳ１０９に進む。本ステップでは、例えば、図３に示すような表示を画面表示部６に行って、ユーザに対して無線機器の登録（ペアリング）を促す。図３はナビゲーション用に表示されている地図上に登録促しのメッセージダイアログを表示させた例である。なお、無線機器の登録促しは図３のように画面に表示して報知するだけでなく、音声再生部５を報知手段として機能させて音声により報知させてもよいし、表示と音声とを組み合せて行ってもよい。即ち、記憶装置７に記憶されている履歴情報を参照して同じ無線機器が複数回検出された場合に報知している。 On the other hand, in step S108 as a notification step, a registration prompt is displayed for the wireless device name that has been found a predetermined number of times or more in step S106, and the process proceeds to step S109. In this step, for example, a display as shown in FIG. 3 is performed on the screen display unit 6 to prompt the user to register (pair) the wireless device. FIG. 3 shows an example in which a registration prompt message dialog is displayed on the map displayed for navigation. The registration prompt for the wireless device is not only displayed on the screen and informed as shown in FIG. 3, but may be informed by voice by causing the audio reproduction unit 5 to function as an informing means, or a combination of display and audio. You may go. That is, notification is made when the same wireless device is detected a plurality of times with reference to the history information stored in the storage device 7.
　次に、ステップＳ１０９において、ステップＳ１０８で表示した無線機器の登録処理を行ってステップＳ１１０に進む。即ち、ペアリングを行って当該登録内容を、例えば記憶装置７に記憶する。 Next, in step S109, the wireless device registration process displayed in step S108 is performed, and the process proceeds to step S110. That is, pairing is performed and the registered content is stored in the storage device 7, for example.
　次に、ステップＳ１１０において、登録成功か否かを判断し、成功の場合（ＹＥＳの場合）はステップＳ１１１に進み、失敗の場合（ＮＯの場合）は終了する。なお、本ステップで失敗と判断されるのは、通信プロトコルなどの機器の動作上登録が失敗した場合以外に、図３の画面で「いいえ」を選択した場合などユーザが登録を拒否した場合も含める。 Next, in step S110, it is determined whether or not the registration is successful. If successful (YES), the process proceeds to step S111, and if failed (NO), the process ends. It should be noted that this step is determined to have failed not only when registration fails due to operation of the device such as the communication protocol, but also when the user refuses registration, such as when “No” is selected on the screen of FIG. include.
　次に、ステップＳ１１１において、接続処理を行って終了する。即ち、無線接続部３に携帯電話機１０との接続処理を行わせる。例えば無線機器として携帯電話機１０が登録、接続された場合は、本ステップ以降カーナビゲーション装置１を利用したハンズフリー通話を行うことが可能となる。 Next, in step S111, connection processing is performed and the process ends. That is, the wireless connection unit 3 is connected to the mobile phone 10. For example, when the mobile phone 10 is registered and connected as a wireless device, a hands-free call using the car navigation device 1 can be performed after this step.
　なお、図２に示したフローチャートでは、起動時に各ステップを実行し、発見（検出）された回数が所定回数以上であった場合に登録促し表示を行っていたが、起動回数を区切ってその回数内で所定回数以上発見された場合に登録促し表示を行ってもよい。例えば、初めて発見されてから５回の起動の間に３回以上発見された無線機器は登録促し表示を行い、発見回数が２回以下の無線機器は発見回数をリセットしてもよい。このようにすることにより、稀にしか乗車しない乗員の無線機器の発見回数が蓄積されて登録促しされることを防止できる。 In the flowchart shown in FIG. 2, each step is executed at the time of activation, and when the number of times of discovery (detection) is a predetermined number or more, registration prompting is displayed. If it is found more than a predetermined number of times, registration prompting may be displayed. For example, a wireless device that has been discovered three times or more during five activations after the first discovery may be prompted to register, and a wireless device with a discovery count of 2 or less may reset the discovery count. By doing so, it is possible to prevent the number of times of finding the wireless device of the occupant who gets on rarely from being accumulated and being prompted to register.
　また、図２に示したフローチャートは、カーナビゲーション装置１の起動時に単に発見（検出）された回数が所定回数以上であった場合に登録促し表示を行っていたが、図４に示すように案内経路があるか否かを判断するようにしてもよい。図４に示したフローチャートではステップＳ１０２とＳ１０３の間にステップＳ１１２として案内経路有りか否かを判断して、ありの場合は終了し、なしの場合はステップＳ１０３に進むようにしている。即ち、車両を目的地まで誘導していない場合に、無線機器の検出を行っている。つまり、経路探索部８により目的地までの経路が探索され案内されている場合は、ユーザ以外の乗員もいる可能性が高く、無線機器の検出を行うと不要な無線機器を検出してしまう可能性があるが、目的地までの案内を行っていない場合は、通勤などでユーザのみが乗車している可能性が高いと判断できるため、その場合のみ無線機器の検出を行わせることで、ユーザの所有する無線機器のみを検出することができる。 In the flowchart shown in FIG. 2, the registration prompting display is performed when the number of times of discovery (detection) when the car navigation apparatus 1 is started is equal to or more than a predetermined number. However, as shown in FIG. It may be determined whether there is a route. In the flowchart shown in FIG. 4, it is determined whether or not there is a guide route between steps S102 and S103 as step S112. If yes, the process ends. If not, the process proceeds to step S103. That is, when the vehicle is not guided to the destination, the wireless device is detected. In other words, when a route to the destination is searched and guided by the route search unit 8, there is a high possibility that there is an occupant other than the user, and if a wireless device is detected, an unnecessary wireless device may be detected. However, if there is no guidance to the destination, it can be determined that there is a high possibility that only the user is on the road due to commuting, etc. Only wireless devices owned by can be detected.
　本実施例によれば、カーナビゲーション装置１の起動時に、接続可能な無線機器の検索を行って、その結果を記憶装置７に記憶し、無線接続制御部４が検索されて発見された回数が予め定めた所定以上の回数ある無線機器がある場合は、その無線機器に登録するように促す表示を画面表示部６に行わせるので、複数の起動回数中に何度も発見される無線機器はユーザ等の所有する無線機器であると判定することができるために、偶然発見される無線機器を排除することができ、ユーザまたはカーナビゲーション装置１を使用する頻度の高い人物の所有する無線機器のうち接続可能なものを発見して接続を促すことができる。 According to the present embodiment, when the car navigation device 1 is activated, a search for connectable wireless devices is performed, the result is stored in the storage device 7, and the number of times the wireless connection control unit 4 is searched and found is determined. When there is a wireless device having a predetermined number of times or more, a screen prompting the user to register with the wireless device is displayed on the screen display unit 6. Since it can be determined that the wireless device is owned by a user or the like, a wireless device that is accidentally discovered can be excluded, and a wireless device owned by a user or a person who frequently uses the car navigation device 1 can be excluded. You can find out what can be connected and encourage the connection.
　また、起動時に周辺無線機器検索結果を記録し、その記録に基づいて、所定回数以上発見されたか否かを判断している。即ち、複数の起動回数中に所定回数以上同じ無線機器が検出された場合は当該無線機器について画面表示部６に登録促し表示を行っている。このようにすることで、例えば、５回の起動回数中３回発見された無線機器について登録を促すようにすることができる。つまり連続で発見されない場合でも、複数回発見された無線機器について登録を促すことができる。 Also, peripheral wireless device search results are recorded at startup, and it is determined whether or not a predetermined number of times have been found based on the records. That is, when the same wireless device is detected a predetermined number of times or more during a plurality of activation times, the screen display unit 6 is prompted to register and display the wireless device. In this way, for example, it is possible to prompt registration for a wireless device discovered three times out of five activations. In other words, even when the wireless devices are not continuously discovered, registration can be prompted for the wireless devices discovered multiple times.
　次に、本発明の第２の実施例にかかるカーナビゲーション装置１を図５を参照して説明する。なお、前述した第１の実施例と同一部分には、同一符号を付して説明を省略する。 Next, a car navigation apparatus 1 according to a second embodiment of the present invention will be described with reference to FIG. The same parts as those in the first embodiment described above are denoted by the same reference numerals and description thereof is omitted.
　本実施例は、構成は図１と同一であるが、外部機器接続動作が異なる。図５に本実施例における外部機器接続動作のフローチャートを示す。 This embodiment has the same configuration as that shown in FIG. 1, but the external device connection operation is different. FIG. 5 shows a flowchart of the external device connection operation in this embodiment.
　まず、ステップＳ２０１において、登録済み無線機器接続処理を行いステップＳ２０２に進む。本ステップはステップＳ１０１と同様に、既に登録されている無線機器がある場合、無線接続部３にその無線機器への接続を試みさせる。 First, in step S201, a registered wireless device connection process is performed, and the process proceeds to step S202. Similar to step S101, this step causes the wireless connection unit 3 to attempt connection to the wireless device when there is a wireless device already registered.
　次に、ステップＳ２０２において、接続機器があるか否かを判断し、ある場合（ＹＥＳの場合）は終了し、無い場合（ＮＯの場合）はステップＳ２０３に進む。本ステップはステップＳ１０２と同様に、接続機器がある場合はステップＳ２０１による処理で当該機器が接続されているので本フローチャートを終了し、接続機器が無い場合は、以降の処理を行う。 Next, in step S202, it is determined whether there is a connected device. If there is a connected device (YES), the process ends. If not (NO), the process proceeds to step S203. In this step, as in step S102, if there is a connected device, the device is connected in the process in step S201, and thus this flowchart is terminated. If there is no connected device, the subsequent processing is performed.
　次に、ステップＳ２０３において、周辺無線機器検索結果記録を行いステップＳ２０４に進む。本ステップはステップＳ１０３と同様に、無線機器を検索し発見された無線機器の情報を例えば記憶装置７などに記憶する処理を行っている。 Next, in step S203, the peripheral wireless device search result is recorded, and the process proceeds to step S204. Similar to step S103, this step performs a process of searching for a wireless device and storing information on the discovered wireless device in the storage device 7, for example.
　次に、ステップＳ２０４において、ステップＳ２０３で検索した結果発見された周辺無線機器の数（発見機器数）を変数Ｍに設定するとともに、発見機器番号を示す変数Ｎを０にリセットしてステップＳ２０５に進む。 Next, in step S204, the number of peripheral wireless devices discovered as a result of the search in step S203 (the number of discovered devices) is set to the variable M, and the variable N indicating the discovered device number is reset to 0, and the flow returns to step S205. move on.
　次に、ステップＳ２０５において、発見機器番号Ｎが発見機器数Ｍと同じ値か否かを判断し、同じ値である場合（ＹＥＳの場合）はステップＳ２０６に進み、同じ値で無い場合（ＮＯの場合）はステップＳ２０７に進む。 Next, in step S205, it is determined whether or not the discovered device number N is the same value as the discovered device number M. If it is the same value (YES), the process proceeds to step S206, and if it is not the same value (NO) In the case), the process proceeds to step S207.
　次に、ステップＳ２０６において、所定時間待機してステップＳ２０２に戻る。本ステップでは、ステップＳ２０５において、発見された全ての機器において所定回数以上の発見記録が無いと判断されたので、無線機器の検出に一定時間間隔を空けるために待機させ、再度ステップＳ２０２からの動作を行わせる。即ち、定期的に無線機器の検出を行っている。 Next, in step S206, the process waits for a predetermined time and returns to step S202. In this step, since it is determined in step S205 that there is no discovery record more than a predetermined number of times in all discovered devices, the wireless device detection is made to wait for a certain time interval, and the operation from step S202 is performed again. To do. That is, the wireless device is periodically detected.
　一方、ステップＳ２０７において、発見機器番号Ｎが所定回数以上発見された記録があるか否かを判断し、ある場合（ＹＥＳの場合）はステップＳ２０９に進み、無い場合（ＮＯの場合）はステップＳ２０８に進む。本ステップでは、発見機器番号Ｎを付与された機器について、記憶装置７を参照して、過去に発見された記録が予め定めた所定回数以上（少なくとも２回以上）であった場合は記録ありと判断している。 On the other hand, in step S207, it is determined whether or not there is a record in which the discovered device number N has been discovered a predetermined number of times or more. If yes (YES), the process proceeds to step S209. If not (NO), step S208 is performed. Proceed to In this step, with respect to the device to which the discovered device number N is assigned, with reference to the storage device 7, if the previously discovered record is a predetermined number of times or more (at least twice or more), there is a record. Deciding.
　次に、ステップＳ２０８において、発見機器番号Ｎを１加算してステップＳ２０５に戻る。 Next, in step S208, the discovered device number N is incremented by 1, and the process returns to step S205.
　一方、ステップＳ２０９においては、ステップＳ２０７において所定回数以上発見された無線機器名に対する登録促しの表示を行ってステップＳ２１０に進む。勿論、本実施例においても、登録促しは表示に限らず音声により行ってもよい。 On the other hand, in step S209, a registration prompt is displayed for the wireless device name found in the predetermined number of times in step S207, and the process proceeds to step S210. Of course, also in the present embodiment, registration prompting is not limited to display but may be performed by voice.
　次に、ステップＳ２１０において、ステップＳ２０８で表示した無線機器の登録処理を行ってステップＳ２１１に進む。即ち、ペアリングを行って当該登録内容を、例えば記憶装置７に記憶する。 Next, in step S210, the wireless device registration process displayed in step S208 is performed, and the process proceeds to step S211. That is, pairing is performed and the registered content is stored in the storage device 7, for example.
　次に、ステップＳ２１１において、登録成功か否かを判断し、成功の場合（ＹＥＳの場合）はステップＳ２１２に進み、失敗の場合（ＮＯの場合）は終了する。 Next, in step S211, it is determined whether or not the registration is successful. If successful (YES), the process proceeds to step S212, and if failed (NO), the process ends.
　次に、ステップＳ２１２において、接続処理を行って終了する。即ち、無線接続部３に携帯電話機１０との接続処理を行わせる。例えば無線機器として携帯電話機１１０が登録、接続された場合は、本ステップ以降カーナビゲーション装置１を利用したハンズフリー通話を行うことが可能となる。 Next, in step S212, connection processing is performed and the process ends. That is, the wireless connection unit 3 is connected to the mobile phone 10. For example, when the mobile phone 110 is registered and connected as a wireless device, a hands-free call using the car navigation device 1 can be performed after this step.
　本実施例のフローチャートは上述したように、起動時に一度だけ実行するのではなくカーナビゲーション装置１の起動後に所定時間待機して（定期的に）周辺無線機器の検索を行い、所定回数以上発見された無線機器がある場合は当該無線機器の登録促し表示を行っている。 As described above, the flowchart of the present embodiment is not executed only once at the time of activation, but waits for a predetermined time after the activation of the car navigation device 1 (periodically), searches for peripheral wireless devices, and is found more than a predetermined number of times. If there is a wireless device, a registration prompt for the wireless device is displayed.
　本実施例によれば、カーナビゲーション装置１の起動後に、接続可能な無線機器の検索を所定時間間隔で行って、その結果を記憶装置７に記憶し、検索されて発見された回数が予め定めた所定以上の回数ある無線機器がある場合は、その無線機器に登録するように表示或いは音声により促す報知を行うので、１回の使用期間に何度も検出される無線機器は、例えば車外などの偶然に検出される無線機器ではなく、ユーザ等の身の回りにある無線機器であると判定することができる。 According to the present embodiment, after the car navigation device 1 is activated, a search for connectable wireless devices is performed at predetermined time intervals, the result is stored in the storage device 7, and the number of times found by searching is determined in advance. If there is a wireless device with a predetermined number of times or more, a notification that prompts the user to register or register with the wireless device is given, so that the wireless device that is detected many times during one use period is, for example, outside the vehicle It is possible to determine that the wireless device is not a wireless device detected by accident but a wireless device around the user.
　なお、本実施例においても、図４に示したような案内経路があるか否かを判断するようにして、案内経路が無しの場合にのみ表示或いは音声による登録促しの報知が行われるようにしてもよい。 Also in this embodiment, it is determined whether or not there is a guide route as shown in FIG. 4 so that only when there is no guide route, a registration prompt notification is displayed or displayed. May be.
　また、上述した２つの実施例において、周辺無線機器を検索した際に無線接続部３で電波強度を検出し、無線接続制御部４は、電波強度が所定の強度以上の場合のみ、発見された無線機器として検索結果を記憶するようにしてもよい。このようにすることにより、カーナビゲーション装置１の近傍にある無線機器のみを検出することができ、例えば車外にある無線機器などを検出してしまう可能性を少なくすることができる。 In the two embodiments described above, the radio connection unit 3 detects the radio field intensity when searching for peripheral wireless devices, and the radio connection control unit 4 is found only when the radio field intensity is equal to or higher than a predetermined level. The search result may be stored as a wireless device. In this way, only wireless devices in the vicinity of the car navigation device 1 can be detected, and for example, the possibility of detecting wireless devices outside the vehicle can be reduced.
　また、上述した２つの実施例においては、１回のフローチャート実行中に１回報知し終えた後、終了するが、発見機器数の中で登録促し対象が複数ある場合は、繰り返し表示或いは音声による登録促しの報知を行っても良い。 Further, in the above-described two embodiments, the notification ends once after execution of one flowchart, but ends. However, when there are a plurality of registration urging targets in the number of discovered devices, repeated display or voice is used. Notification of registration prompting may be performed.
　また、上述した２つの実施例では、無線通信の方式としてＢｌｕｅｔｏｏｔｈ（登録商標）で説明したが、それに限らず、接続可能機器を検出、登録して通信を行う方式であれば、例えば、ＩＥＥＥ８０２．１１シリーズで規定される方式などの他の方式でも適用可能である。 In the two embodiments described above, Bluetooth (registered trademark) has been described as a wireless communication method. However, the present invention is not limited to this, and any method that detects and registers a connectable device and performs communication, for example, IEEE802. Other methods such as those defined in the 11 series are also applicable.
　また、上述した２つの実施例では、カーナビゲーション装置１と携帯電話機１０で説明したが、それに限るものではなく、例えば、無線通信装置としてのカーオーディオと外部機器としてのポータブルオーディオなどで通信を行ってポータブルオーディオ内の楽曲をカーオーディオで再生する機能に適用してもよいし、車両そのものに本発明の無線通信装置を搭載し、携帯電話機１０などと通信するようにしてもよい。その場合は、カーオーディオの表示部や車両のメータ内やインストルメントパネル等に設けられている表示装置等や車両に取り付けられているスピーカ等を用いて登録促しの報知を行えばよい。 In the two embodiments described above, the car navigation device 1 and the mobile phone 10 have been described. However, the present invention is not limited to this. For example, communication is performed using a car audio as a wireless communication device and a portable audio as an external device. Thus, the present invention may be applied to a function of reproducing music in portable audio with car audio, or the wireless communication device of the present invention may be mounted on the vehicle itself to communicate with the mobile phone 10 or the like. In that case, the registration prompting notification may be performed using a display unit provided in a car audio display unit, a vehicle meter, an instrument panel, or the like, a speaker attached to the vehicle, or the like.
　さらに、上述した２つの実施例において、既に記憶装置７等に登録されている無線機器がある場合は、新たな無線機器の登録促し表示を行わなくともよい。このようにすることにより、ユーザは既に無線機器（外部機器）の接続が可能であることを認識しているので、登録促しによる接続機能の周知は不要とみなすことができる。また、一度ユーザが登録を拒否した場合は当該機器に関しては登録促し非対象機器として記憶装置７等に記憶して、以後は当該機器が検出されても登録促しを行わないようにしてもよい。このようにすることにより、ユーザが接続したくない無線機器を何度も表示してユーザが煩わしく感じることを防止できる。 Furthermore, in the above-described two embodiments, when there is a wireless device already registered in the storage device 7 or the like, it is not necessary to display a registration prompt for a new wireless device. By doing so, since the user has already recognized that the wireless device (external device) can be connected, it can be considered that the connection function by the registration prompt is not necessary. Further, once the user refuses registration, the device may be prompted to register and stored as a non-target device in the storage device 7 or the like, and thereafter the registration prompt may not be performed even if the device is detected. By doing in this way, it can prevent that a user feels bothersome by displaying the radio equipment which a user does not want to connect many times.
