Thereby, the mounting table 100 can perform various operations using the position detected by the position detection unit 20. Examples of the use of the position detected by the position detection unit 20 include, for example, an example of a charging stand and a short-range wireless device as will be described later, but the present invention is not limited to this, and the mounted portable wireless device It can be generally applied to a mounting table for detecting the position of the machine.
　ここで、携帯無線機１は、無線通信のためのアンテナ５を備えている。位置検出部２０は、マトリクスコイルや配線等の導電体を備えているため、アンテナ５と位置検出部２０とが接近すると、アンテナ５の共振周波数がずれたり、位置検出コイルと当該アンテナとが結合して放射が妨げられる等、アンテナ５のアンテナ特性が劣化することがある。 Here, the portable wireless device 1 includes an antenna 5 for wireless communication. Since the position detection unit 20 includes a conductor such as a matrix coil and wiring, when the antenna 5 and the position detection unit 20 approach each other, the resonance frequency of the antenna 5 is shifted or the position detection coil and the antenna are coupled. As a result, the antenna characteristics of the antenna 5 may deteriorate, for example, radiation may be hindered.
　これに対し、載置台１００は、位置検出部移動部２１を備えているため、適宜、位置検出部２０と携帯無線機１とを接近または離間させることが可能となる。これにより、載置台１００に載置された携帯無線機１の位置を検出する場合であっても、位置の検出を行わない間は位置検出部２０を携帯無線機１から遠ざけることができるため、位置検出部２０に起因する、アンテナ５のアンテナ特性の劣化を抑制することができる。 On the other hand, since the mounting table 100 includes the position detection unit moving unit 21, the position detection unit 20 and the portable wireless device 1 can be appropriately approached or separated from each other. Thereby, even if it is a case where the position of the portable radio | wireless machine 1 mounted in the mounting base 100 is detected, since the position detection part 20 can be kept away from the portable radio | wireless machine 1 while not detecting a position, Deterioration of the antenna characteristics of the antenna 5 due to the position detection unit 20 can be suppressed.
　（制御手段を備えた例）
　図３は、載置台１００が制御部（制御手段）３０を備えている場合の構成の例を概略的に示す模式図である。図４は、載置台１００が制御部３０を備えている場合の構成の例を概略的に示すブロック図である。 (Example with control means)
FIG. 3 is a schematic diagram schematically showing an example of the configuration when the mounting table 100 includes a control unit (control means) 30. FIG. 4 is a block diagram schematically illustrating an example of a configuration when the mounting table 100 includes the control unit 30.
　まず、制御部３０の配置について説明する。図３の（ａ）に示すように、制御部３０は、位置検出部２０に付随するように設けることもできる。このように構成することにより、可動する配線を減らすことができる。また、図３の（ｂ）に示すように、制御部３０を、位置検出部２０とは独立させて設けてもよい。この場合には、例えば、制御部３０と位置検出部２０とを可撓性を有する配線によって接続すればよい。 First, the arrangement of the control unit 30 will be described. As shown in FIG. 3A, the control unit 30 can be provided so as to accompany the position detection unit 20. With this configuration, movable wiring can be reduced. Further, as shown in FIG. 3B, the control unit 30 may be provided independently of the position detection unit 20. In this case, for example, the control unit 30 and the position detection unit 20 may be connected by a flexible wiring.
　次に、制御部３０の動作について説明する。図４の（ａ）に示すように、一例において、制御部３０は、位置検出部移動部２１に対して、位置検出部２０が移動すべき位置を指定する制御信号Ｃ１を送るものであり得る。例えば、位置検出部移動部２１が、図１の（ｃ）のように構成されている場合、制御部３０は、歯車２１ｂを回転させるモータ等に対して、歯車２１ｂを所定の角度回転させるための制御信号Ｃ１を送ればよい。 Next, the operation of the control unit 30 will be described. As shown in (a) of FIG. 4, in one example, the control unit 30 may send a control signal C <b> 1 that designates a position to which the position detection unit 20 should move to the position detection unit movement unit 21. . For example, when the position detection unit moving unit 21 is configured as shown in FIG. 1C, the control unit 30 rotates the gear 21b by a predetermined angle with respect to a motor or the like that rotates the gear 21b. The control signal C1 may be sent.
　このように、制御部３０が制御信号Ｃ１を位置検出部移動部２１に送るようになっていることにより、載置台１００は、位置検出部２０の移動を自動的に行うことができる。 As described above, since the control unit 30 is configured to send the control signal C1 to the position detection unit moving unit 21, the mounting table 100 can automatically move the position detection unit 20.
　また、図４の（ｂ）に示すように、他の例において、位置検出部２０は、携帯無線機１の位置の検出が完了したことを示す制御信号Ｃ２を制御部３０に送るものであり、制御部３０は、制御信号Ｃ２を受けた後に、位置検出部移動部２１に対して、位置検出部２０を携帯無線機１から離れた所定の位置に移動させることを指示する制御信号Ｃ３を送るものであり得る。 Further, as shown in FIG. 4B, in another example, the position detection unit 20 sends a control signal C2 indicating that the detection of the position of the portable wireless device 1 is completed to the control unit 30. After receiving the control signal C2, the control unit 30 gives a control signal C3 for instructing the position detection unit moving unit 21 to move the position detection unit 20 to a predetermined position away from the portable wireless device 1. It can be sent.
　これを、図５に示すフローチャートを参照して説明すれば、まず、携帯無線機１が載置部１０に載置されると（ステップＳ１）、位置検出部２０が、携帯無線機１の位置を検出し（ステップＳ２）、制御信号Ｃ２を制御部３０に送る。そして、制御信号Ｃ２を受けた制御部３０は、制御信号Ｃ３を位置検出部移動部２１に送り、位置検出部移動部２１は、制御信号Ｃ３に基づき、位置検出部２０を移動させる（ステップＳ３）。 This will be described with reference to the flowchart shown in FIG. 5. First, when the portable wireless device 1 is placed on the placement unit 10 (step S <b> 1), the position detection unit 20 detects the position of the portable wireless device 1. Is detected (step S2), and a control signal C2 is sent to the control unit 30. The control unit 30 that has received the control signal C2 sends the control signal C3 to the position detection unit moving unit 21, and the position detection unit moving unit 21 moves the position detection unit 20 based on the control signal C3 (step S3). ).
　このように、制御部３０が、制御信号Ｃ２を受けてから、制御信号Ｃ３を送るようになっていることにより、載置台１００は、適切なタイミングにおいて、位置検出部２０を携帯無線機１から離間させることができる。これにより、携帯無線機１の位置の検出が完了し、位置の検出が必要でない間、位置検出部２０と携帯無線機１とを離間させて、アンテナ５のアンテナ特性の劣化を好適に抑制することができる。 As described above, since the control unit 30 receives the control signal C2 and sends the control signal C3, the mounting table 100 moves the position detection unit 20 from the portable wireless device 1 at an appropriate timing. Can be separated. Thereby, while the detection of the position of the portable wireless device 1 is completed and the detection of the position is not necessary, the position detection unit 20 and the portable wireless device 1 are separated from each other, and the deterioration of the antenna characteristics of the antenna 5 is suitably suppressed. be able to.
　また、図４の（ｃ）に示すように、さらに他の例において、位置検出部２０は、携帯無線機１の位置の検出が完了したことを示す制御信号Ｃ２と、携帯無線機１の位置を示す制御信号Ｃ４とを制御部３０に送るものであり、制御部３０は、制御信号Ｃ２およびＣ４を受けた後に、位置検出部移動部２１に対して、位置検出部２０が移動すべき位置を指定する制御信号Ｃ５を送るものであり得る。そして、制御部３０は、携帯無線機１の位置を示す制御信号Ｃ４に基づき、位置検出部２０が移動すべき位置を決定し、制御信号Ｃ５を生成する。 Further, as shown in FIG. 4C, in yet another example, the position detection unit 20 includes a control signal C2 indicating that the detection of the position of the portable wireless device 1 is completed, and the position of the portable wireless device 1. Control signal C4 indicating the position to which the position detection unit 20 should move relative to the position detection unit moving unit 21 after receiving the control signals C2 and C4. It is possible to send a control signal C5 designating. And the control part 30 determines the position which the position detection part 20 should move based on the control signal C4 which shows the position of the portable radio | wireless machine 1, and produces | generates the control signal C5.
　このとき、例えば、制御信号Ｃ４は、載置部１０（上面）を２次元平面と見た場合の携帯無線機１の検出座標を示す情報であり得る。これに対し、制御部３０は、位置検出部２０の可動範囲の中で、位置検出部２０の中心または端部が、当該検出座標から最も離れるような位置に位置検出部２０を水平方向に移動させるようになっていてもよい。これにより、制御部３０は、効率的に、位置検出部２０を携帯無線機１から離間させることができる。 At this time, for example, the control signal C4 may be information indicating the detected coordinates of the portable wireless device 1 when the placement unit 10 (upper surface) is viewed as a two-dimensional plane. In contrast, the control unit 30 moves the position detection unit 20 in the horizontal direction to a position where the center or end of the position detection unit 20 is farthest from the detection coordinates within the movable range of the position detection unit 20. You may come to let me. Thereby, the control unit 30 can efficiently separate the position detection unit 20 from the portable wireless device 1.
　また、他の実施形態において、位置検出部２０が独立して移動可能な複数の区画から構成され、制御部３０は、検出座標に対応する区画のみを移動させるようになっていてもよい。この場合、例えば、位置検出部２０は、縦横ｎ×ｍ個の区画に分割され、位置検出部移動部２１は、位置検出部２０の各区画を独立して移動させることができるように構成されている。制御部３０は、位置検出部移動部２１に制御信号Ｃ５を送ることにより、位置検出部２０の区画のうち、無線通信機１のアンテナに影響を与え得る区画（例えば、制御信号Ｃ４が示す検出座標が含まれる区画）のみを無線通信機１から離間するように移動させる。これにより、無線通信機１に対する位置検出部２０の影響を抑制するとともに、無線通信機１が載置されていない領域において、引き続き位置検出を行うことができる。これにより、例えば、複数台の無線通信機の充電等を行う載置台（位置検出手段付き充電台）を好適に構成することができる。すなわち、一つの無線通信機が載置されているときに、当該一つの無線通信機に対する位置検出部２０の影響を抑制するとともに、当該一つの無線通信機が載置されていない領域において、引き続き位置検出を行うことができるため、さらに他の無線通信機が載置されたときに、位置検出部２０が、首尾よく当該他の無線通信機の位置を検出することができる。これによって、複数の無線通信機が載置される載置台を好適に構成することができる。 In another embodiment, the position detection unit 20 may be configured by a plurality of sections that can move independently, and the control unit 30 may move only the sections corresponding to the detected coordinates. In this case, for example, the position detection unit 20 is divided into n × m vertical and horizontal sections, and the position detection unit moving unit 21 is configured to be able to move each section of the position detection unit 20 independently. ing. The control unit 30 sends a control signal C5 to the position detection unit moving unit 21, thereby dividing a section of the position detection unit 20 that can affect the antenna of the wireless communication device 1 (for example, detection indicated by the control signal C4). Only the section including the coordinates) is moved away from the wireless communication device 1. Thereby, while suppressing the influence of the position detection part 20 with respect to the radio | wireless communication apparatus 1, a position detection can be continued in the area | region where the radio | wireless communication apparatus 1 is not mounted. Thereby, for example, a mounting table (charging table with position detecting means) for charging a plurality of wireless communication devices can be suitably configured. That is, when one wireless communication device is placed, the influence of the position detection unit 20 on the one wireless communication device is suppressed, and in the region where the one wireless communication device is not placed, Since position detection can be performed, the position detection unit 20 can successfully detect the position of the other wireless communication device when another wireless communication device is placed. Thereby, a mounting table on which a plurality of wireless communication devices are mounted can be suitably configured.
　このように、制御部３０が、制御信号Ｃ２およびＣ４を受けてから、制御信号Ｃ４に基づいて位置検出部２０が移動すべき位置を決定し、制御信号Ｃ５を位置検出部移動部２１に対して送ることにより、位置検出部移動部２１の動作を最適化することができる。 Thus, after the control unit 30 receives the control signals C2 and C4, the position detection unit 20 determines a position to move based on the control signal C4, and sends the control signal C5 to the position detection unit movement unit 21. The operation of the position detection unit moving unit 21 can be optimized.
　〔充電台〕
　また、本発明に係る載置台は、携帯無線機の充電台として構成してもよい。図６は、本発明の一実施形態に係る充電台１０１の基本的な構成を概略的に示す模式図である。また、図７は、充電台１０１の基本的な構成の例を概略的に示すブロック図である。また、図８は、充電台１０１の動作の例を説明するフローチャートである。 [Charging stand]
Moreover, you may comprise the mounting base which concerns on this invention as a charging stand of a portable radio. FIG. 6 is a schematic diagram schematically showing a basic configuration of the charging stand 101 according to the embodiment of the present invention. FIG. 7 is a block diagram schematically showing an example of the basic configuration of the charging stand 101. FIG. 8 is a flowchart for explaining an example of the operation of the charging stand 101.
　図６および図７に示すように、充電台１０１は、載置部１０、位置検出部２０、位置検出部移動部２１および制御部３０といった載置台１００と同様の部材に加えて、携帯無線機２の充電のための、充電用送電コイル（送電部）４０および送電コイル移動部（送電部移動手段）４１を備えている。また、携帯無線機２は、アンテナ５の他、充電用受電コイル６を備えている。 As shown in FIGS. 6 and 7, the charging stand 101 includes a portable wireless device in addition to the same members as the placement table 100 such as the placement unit 10, the position detection unit 20, the position detection unit moving unit 21, and the control unit 30. 2, a charging power transmission coil (power transmission unit) 40 and a power transmission coil moving unit (power transmission unit moving means) 41 are provided. The portable wireless device 2 includes a charging power receiving coil 6 in addition to the antenna 5.
　充電用送電コイル４０は、携帯無線機２が備える充電用受電コイル６との間で非接触電力電送を行うものであり、例えば、電磁誘導方式に適合する公知の送電コイルを用いればよい（例えば、Qi System Description Wireless Power Transfer, Volume I:Low Power, Part 1:Interface Definition, Version 1.0.2, April 2011を参照のこと）。また、充電台１０１は、充電用送電コイル４０を制御するための図示しない制御回路および充電用送電コイル４０に電力を供給するための図示しない電源を備えている。 The charging power transmission coil 40 performs non-contact power transmission with the charging power reception coil 6 included in the portable wireless device 2. For example, a known power transmission coil suitable for an electromagnetic induction method may be used (for example, Qi, System, Description, Wireless, Power, Transfer, Volume, I: Low, Power, Part, 1: Interface, Definition, Version, 1.0.2, and April, 2011). Further, the charging stand 101 includes a control circuit (not shown) for controlling the charging power transmission coil 40 and a power supply (not shown) for supplying power to the charging power transmission coil 40.
　なお、本発明は、電磁誘導方式で非接触電力伝送を行う形態に限定されず、静電誘導方式、磁界／電界共鳴方式、線路／線路結合方式、線路／共振器結合方式、マイクロ波送電方式、レーザ送電方式等を用いてもよい。この場合、充電用送電コイル４０に替えて、各方式に適合する公知の送電部を用いればよい。 In addition, this invention is not limited to the form which performs non-contact electric power transmission by an electromagnetic induction system, An electrostatic induction system, a magnetic field / electric field resonance system, a line / line coupling system, a line / resonator coupling system, a microwave power transmission system Alternatively, a laser power transmission method or the like may be used. In this case, instead of the charging power transmission coil 40, a known power transmission unit suitable for each method may be used.
　送電コイル移動部４１は、位置検出部移動部２１と同様に、制御部３０からの制御に応じて、充電用送電コイル４０を移動させるものであればよい。 The power transmission coil moving unit 41 may be any unit that moves the charging power transmission coil 40 in accordance with control from the control unit 30, similarly to the position detection unit moving unit 21.
　充電用送電コイル４０は、例えば、図６に示すように、位置検出部２０よりも載置部１０側に配置され得る。これにより、充電用送電コイル４０の移動と、位置検出部２０の移動とが衝突することを好適に避けることができる。但し、充電用送電コイル４０の配置はこれに限定されず、例えば、位置検出部２０が水平方向に移動するものであれば、充電用送電コイル４０が、位置検出部２０よりも載置部１０とは反対側に配置されていても、充電用送電コイル４０の移動と、位置検出部２０の移動とが衝突することを避けることは可能である。 For example, as shown in FIG. 6, the charging power transmission coil 40 may be disposed closer to the placement unit 10 than the position detection unit 20. Thereby, it can avoid suitably that the movement of the power transmission coil 40 for charge and the movement of the position detection part 20 collide. However, the arrangement of the charging power transmission coil 40 is not limited to this. For example, if the position detection unit 20 moves in the horizontal direction, the charging power transmission coil 40 is more than the mounting unit 10 than the position detection unit 20. It is possible to avoid the collision of the movement of the charging power transmission coil 40 and the movement of the position detection unit 20 even if arranged on the opposite side.
　続いて、制御部３０の動作について説明する。なお、制御部３０と位置検出部２０および位置検出部移動部２１との間の制御信号の送受については、載置台１００における説明と同様であるので、説明を省略する。 Subsequently, the operation of the control unit 30 will be described. Note that the transmission and reception of control signals between the control unit 30 and the position detection unit 20 and the position detection unit moving unit 21 are the same as those described in the mounting table 100, and thus the description thereof is omitted.
　図７の（ａ）に示すように、一例において、制御部３０は、位置検出部２０から携帯無線機２の位置を示す制御信号Ｃ４を受け取ると、送電コイル移動部４１に制御信号Ｃ６を送ることにより、充電用送電コイル４０を充電用受電コイル６に接近させる。これにより、好適に携帯無線機２の充電を行うことができる。また、制御部３０は、載置台１００における制御と同様に、位置検出部２０による携帯無線機２の位置の検出が完了後、位置検出部２０を載置部１０から遠ざけるように移動させるので、アンテナ５のアンテナ特性の劣化を抑制することができる。 As shown in FIG. 7A, in one example, when receiving a control signal C4 indicating the position of the portable wireless device 2 from the position detection unit 20, the control unit 30 sends a control signal C6 to the power transmission coil moving unit 41. Thus, the charging power transmission coil 40 is brought close to the charging power reception coil 6. Thereby, the portable wireless device 2 can be suitably charged. Further, the control unit 30 moves the position detection unit 20 away from the mounting unit 10 after the detection of the position of the portable wireless device 2 by the position detection unit 20 is completed, similarly to the control in the mounting table 100. Deterioration of antenna characteristics of the antenna 5 can be suppressed.
　これを、図８の（ａ）に示すフローチャートを参照して説明すれば、まず、携帯無線機１が載置部１０に載置されると（ステップＳ１１）、位置検出部２０が、携帯無線機２の位置を検出し（ステップＳ１２）、制御信号Ｃ２およびＣ４を制御部３０に送る。そして、制御信号Ｃ２およびＣ４を受けた制御部３０は、制御信号Ｃ５を位置検出部移動部２１に送り、位置検出部移動部２１は、制御信号Ｃ５に基づき、位置検出部２０を移動させる（ステップＳ１３）。また、並行して、制御部３０は、制御信号Ｃ６を送電コイル移動部４１に送り、送電コイル移動部４１は、制御信号Ｃ６に基づき、充電用送電コイル４０を充電用受電コイル６に接近するように移動させる（ステップＳ１３）。そして、充電用送電コイル４０と充電用受電コイル６との間で非接触電力電送を行い、充電を実行する（ステップＳ１４）。 This will be described with reference to the flowchart shown in FIG. 8A. First, when the portable wireless device 1 is placed on the placement unit 10 (step S11), the position detection unit 20 is moved to the portable wireless device. The position of the machine 2 is detected (step S12), and control signals C2 and C4 are sent to the control unit 30. And the control part 30 which received control signals C2 and C4 sends the control signal C5 to the position detection part moving part 21, and the position detection part movement part 21 moves the position detection part 20 based on the control signal C5 ( Step S13). In parallel, the control unit 30 sends a control signal C6 to the power transmission coil moving unit 41, and the power transmission coil moving unit 41 brings the charging power transmission coil 40 closer to the charging power receiving coil 6 based on the control signal C6. (Step S13). Then, non-contact power transmission is performed between the charging power transmission coil 40 and the charging power reception coil 6 to perform charging (step S14).
　このように、制御部３０が、位置検出部２０が携帯無線機２の位置を検出した後、位置検出部２０を載置部１０から遠ざけるとともに、位置検出部２０が検出した位置に基づいて、充電用送電コイル４０を充電用受電コイル６に接近させることにより、充電台１０１は、アンテナ５のアンテナ特性の劣化を抑制しつつ、充電を効率的に行うことができる。 As described above, after the position detection unit 20 detects the position of the portable wireless device 2, the control unit 30 moves the position detection unit 20 away from the placement unit 10 and based on the position detected by the position detection unit 20. By bringing the charging power transmission coil 40 closer to the charging power receiving coil 6, the charging stand 101 can efficiently perform charging while suppressing deterioration of the antenna characteristics of the antenna 5.
　また、制御部３０は、充電を実行中に携帯無線機２が変位（位置ずれ）したときに、再度、携帯無線機２の位置を検出させるようになっていてもよい。この場合、図７の（ｂ）に示すように、充電台１０１は、携帯無線機２の変位を検出するための結合量検出部（変位検出手段）４２を備え得る。 In addition, the control unit 30 may be configured to detect the position of the portable wireless device 2 again when the portable wireless device 2 is displaced (displaced) during charging. In this case, as shown in FIG. 7B, the charging stand 101 can include a coupling amount detection unit (displacement detection means) 42 for detecting the displacement of the portable wireless device 2.
　充電を実行中、結合量検出部４２は、充電用送電コイル４０と充電用受電コイル６との間の結合量を示す制御信号Ｃ７を制御部３０に送る。当該結合量の変化は、携帯無線機２の変位の指標となるため、制御部３０は、制御信号Ｃ７に基づいて携帯無線機２の変位を検知することができる。 During the charging, the coupling amount detection unit 42 sends a control signal C7 indicating the coupling amount between the charging power transmission coil 40 and the charging power receiving coil 6 to the control unit 30. Since the change in the coupling amount serves as an index of displacement of the portable wireless device 2, the control unit 30 can detect the displacement of the portable wireless device 2 based on the control signal C7.
　そして、制御部３０は、携帯無線機２の変位を検知すると、位置検出部２０を載置部１０に接近させることを指示する制御信号Ｃ８を位置検出部移動部２１に送る。制御信号Ｃ８を受けて、位置検出部移動部２１は、位置検出部２０を載置部１０に接近させる。そして、位置検出部２０は、まず、携帯無線機２が載置部１０に載置されているか否かを判定する。携帯無線機２が載置部１０に載置されていれば、携帯無線機２の位置検出を行い、制御信号Ｃ２およびＣ４を制御部３０に送る。携帯無線機２が載置部１０に載置されていなければ、そのままの位置で、次回の充電に備える。 And the control part 30 will transmit the control signal C8 which instruct | indicates that the position detection part 20 approaches the mounting part 10 to the position detection part moving part 21, if the displacement of the portable radio | wireless machine 2 is detected. In response to the control signal C <b> 8, the position detection unit moving unit 21 causes the position detection unit 20 to approach the placement unit 10. Then, the position detection unit 20 first determines whether or not the portable wireless device 2 is placed on the placement unit 10. If the portable wireless device 2 is placed on the placement unit 10, the position of the portable wireless device 2 is detected, and control signals C 2 and C 4 are sent to the control unit 30. If the portable wireless device 2 is not placed on the placement unit 10, it is ready for the next charging at the same position.
　これを、図８の（ｂ）に示すフローチャートを参照して説明すれば、まず、携帯無線機１が載置部１０に載置されると（ステップＳ２１）、位置検出部２０が、携帯無線機２の位置を検出し（ステップＳ２２）、制御信号Ｃ２およびＣ４を制御部３０に送る。そして、制御信号Ｃ２およびＣ４を受けた制御部３０は、制御信号Ｃ５を位置検出部移動部２１に送り、位置検出部移動部２１は、制御信号Ｃ５に基づき、位置検出部２０を移動させる（ステップＳ２３）。また、並行して、制御部３０は、制御信号Ｃ６を送電コイル移動部４１に送り、送電コイル移動部４１は、制御信号Ｃ６に基づき、充電用送電コイル４０を充電用受電コイル６に接近するように移動させる（ステップＳ２３）。そして、充電用送電コイル４０と充電用受電コイル６との間で非接触電力電送を行い、充電を実行する（ステップＳ２４）。 This will be described with reference to the flowchart shown in FIG. 8B. First, when the portable wireless device 1 is placed on the placement unit 10 (step S21), the position detection unit 20 becomes portable wireless. The position of the machine 2 is detected (step S22), and control signals C2 and C4 are sent to the control unit 30. And the control part 30 which received control signals C2 and C4 sends the control signal C5 to the position detection part moving part 21, and the position detection part movement part 21 moves the position detection part 20 based on the control signal C5 ( Step S23). In parallel, the control unit 30 sends a control signal C6 to the power transmission coil moving unit 41, and the power transmission coil moving unit 41 brings the charging power transmission coil 40 closer to the charging power receiving coil 6 based on the control signal C6. (Step S23). Then, non-contact power transmission is performed between the charging power transmission coil 40 and the charging power reception coil 6 to perform charging (step S24).
　そして、制御部３０は、充電が完了したかを判定し（ステップＳ２５）、充電が完了していないときには、制御部３０は、結合量検出部４２からの制御信号Ｃ７に基づいて携帯無線機２の位置ずれを判定する（ステップＳ２６）。位置ずれがなければ、ステップＳ２４に戻って充電を継続する。一方、位置ずれがあったときには、制御部３０は、制御信号Ｃ８を位置検出部移動部２１に送り、位置検出部移動部２１は、制御信号Ｃ８に基づき、位置検出部２０を載置部１０に接近させる（ステップＳ２７）。 Then, the control unit 30 determines whether the charging is completed (step S25). When the charging is not completed, the control unit 30 is based on the control signal C7 from the coupling amount detection unit 42, and the portable wireless device 2 Is determined (step S26). If there is no position shift, the process returns to step S24 to continue charging. On the other hand, when there is a position shift, the control unit 30 sends a control signal C8 to the position detection unit moving unit 21, and the position detection unit moving unit 21 moves the position detection unit 20 to the placement unit 10 based on the control signal C8. (Step S27).
　続いて、位置検出部２０は、携帯無線機２が載置部１０に載置されているか否かを判定する（ステップＳ２８）。携帯無線機２が載置部１０に載置されていれば、ステップＳ２２に戻り、位置検出部２０は、携帯無線機２の位置検出を行う。携帯無線機２が載置部１０に載置されていなければ、位置検出部２０をそのままの位置に待機させる。 Subsequently, the position detection unit 20 determines whether or not the portable wireless device 2 is placed on the placement unit 10 (step S28). If the portable wireless device 2 is placed on the placement unit 10, the process returns to step S <b> 22, and the position detection unit 20 detects the position of the portable wireless device 2. If the portable wireless device 2 is not placed on the placement unit 10, the position detection unit 20 is made to stand by at the same position.
　このように、充電中に、携帯無線機２の位置ずれを検出した場合、位置検出部２０を載置部１０に接近させて、位置検出を行わせることにより、位置情報を更新して、携帯無線機２の位置ずれが生じても、好適に充電を行うことができる。 As described above, when a position shift of the portable wireless device 2 is detected during charging, the position information is updated by bringing the position detection unit 20 close to the placement unit 10 and performing the position detection, thereby carrying the mobile phone. Even if the radio apparatus 2 is misaligned, it can be charged appropriately.
　〔近距離無線装置〕
　また、本発明に係る載置台は、携帯無線機との間で近距離無線通信を行う近距離無線装置（例えば、ＦｅｌｉＣａ（登録商標）リーダ等）として構成してもよい。図９は、本発明の一実施形態に係る近距離無線装置１０２の基本的な構成を概略的に示す模式図である。また、図１０は、近距離無線装置１０２の基本的な構成の例を概略的に示すブロック図である。また、図１１は、近距離無線装置１０２の動作の例を説明するフローチャートである。 (Short range wireless device)
The mounting table according to the present invention may be configured as a short-range wireless device (for example, a FeliCa (registered trademark) reader) that performs short-range wireless communication with a portable wireless device. FIG. 9 is a schematic diagram schematically showing a basic configuration of the short-range wireless apparatus 102 according to the embodiment of the present invention. FIG. 10 is a block diagram schematically illustrating an example of a basic configuration of the short-range wireless device 102. FIG. 11 is a flowchart for explaining an example of the operation of the short-range wireless device 102.
　図９および図１０に示すように、近距離無線装置１０２は、載置部１０、位置検出部２０、位置検出部移動部２１および制御部３０といった載置台１００と同様の部材に加えて、携帯無線機３との間の近距離無線通信のための、近距離無線アンテナ（アンテナ）５０およびアンテナ移動部（アンテナ移動手段）５１を備えている。また、携帯無線機３は、アンテナ５の他、近距離無線アンテナ７を備えている。 As shown in FIGS. 9 and 10, the short-range wireless device 102 is portable in addition to the same members as the mounting table 100 such as the mounting unit 10, the position detection unit 20, the position detection unit moving unit 21, and the control unit 30. A short-range wireless antenna (antenna) 50 and an antenna moving unit (antenna moving means) 51 for short-range wireless communication with the wireless device 3 are provided. In addition to the antenna 5, the portable wireless device 3 includes a short-range wireless antenna 7.
　近距離無線アンテナ５０は、携帯無線機３が備える近距離無線アンテナ７との間で近距離無線通信を行うものであり、公知の近距離無線通信規格（例えば、ＦｅｌｉＣａ（登録商標）、ＩＳＯ／ＩＥＣ１４４４３等を含むＮＦＣ規格）に適合するアンテナを用いればよい。また、近距離無線装置１０２、近距離無線アンテナ５０を介した近距離無線通信を行うための図示しない無線回路を備えている。 The short-range wireless antenna 50 performs short-range wireless communication with the short-range wireless antenna 7 included in the portable wireless device 3, and is a known short-range wireless communication standard (for example, FeliCa (registered trademark), ISO / An antenna conforming to NFC standards including IEC14443 and the like may be used. In addition, a short-range wireless device 102 and a wireless circuit (not shown) for performing short-range wireless communication via the short-range wireless antenna 50 are provided.
　アンテナ移動部５１は、位置検出部移動部２１と同様に、制御部３０からの制御に応じて、近距離無線アンテナ５０を移動させるものであればよい。 The antenna moving unit 51 only needs to move the short-range wireless antenna 50 in accordance with the control from the control unit 30, similarly to the position detection unit moving unit 21.
　近距離無線アンテナ５０は、例えば、図９に示すように、位置検出部２０よりも載置部１０側に配置され得る。これにより、近距離無線アンテナ５０の移動と、位置検出部２０の移動とが衝突することを好適に避けることができる。但し、近距離無線アンテナ５０の配置はこれに限定されず、例えば、位置検出部２０が水平方向に移動するものであれば、近距離無線アンテナ５０が、位置検出部２０よりも載置部１０とは反対側に配置されていても、近距離無線アンテナ５０の移動と、位置検出部２０の移動とが衝突することを避けることは可能である。 For example, as shown in FIG. 9, the short-range wireless antenna 50 can be arranged closer to the placement unit 10 than the position detection unit 20. Thereby, it can avoid suitably that the movement of the short distance radio | wireless antenna 50 and the movement of the position detection part 20 collide. However, the arrangement of the short-range wireless antenna 50 is not limited to this. For example, if the position detection unit 20 moves in the horizontal direction, the short-range wireless antenna 50 is more than the placement unit 10 than the position detection unit 20. It is possible to avoid collision between the movement of the short-range wireless antenna 50 and the movement of the position detection unit 20 even if they are arranged on the opposite side.
　続いて、制御部３０の動作について説明する。なお、制御部３０と位置検出部２０および位置検出部移動部２１との間の制御信号の送受については、載置台１００における説明と同様であるので、説明を省略する。 Subsequently, the operation of the control unit 30 will be described. Note that the transmission and reception of control signals between the control unit 30 and the position detection unit 20 and the position detection unit moving unit 21 are the same as those described in the mounting table 100, and thus the description thereof is omitted.
　図１０の（ａ）に示すように、一例において、制御部３０は、位置検出部２０から携帯無線機３の位置を示す制御信号Ｃ４を受け取ると、アンテナ移動部５１に制御信号Ｃ９を送ることにより、近距離無線アンテナ５０を近距離無線アンテナ７に接近させる。これにより、好適に携帯無線機３との間で近距離無線通信を行うことができる。また、制御部３０は、載置台１００における制御と同様に、位置検出部２０による携帯無線機３の位置の検出が完了後、位置検出部２０を載置部１０から遠ざけるように移動させるので、アンテナ５のアンテナ特性の劣化を抑制することができる。 As shown in FIG. 10A, in one example, when receiving a control signal C4 indicating the position of the portable wireless device 3 from the position detection unit 20, the control unit 30 sends a control signal C9 to the antenna moving unit 51. Thus, the short-range wireless antenna 50 is brought close to the short-range wireless antenna 7. Thereby, near field communication can be suitably performed between the portable wireless devices 3. Further, the control unit 30 moves the position detection unit 20 away from the mounting unit 10 after the detection of the position of the portable wireless device 3 by the position detection unit 20 is completed, similarly to the control in the mounting table 100. Deterioration of antenna characteristics of the antenna 5 can be suppressed.
　これを、図１１の（ａ）に示すフローチャートを参照して説明すれば、まず、携帯無線機１が載置部１０に載置されると（ステップＳ３１）、位置検出部２０が、携帯無線機３の位置を検出し（ステップＳ３２）、制御信号Ｃ２およびＣ４を制御部３０に送る。そして、制御信号Ｃ２およびＣ４を受けた制御部３０は、制御信号Ｃ５を位置検出部移動部２１に送り、位置検出部移動部２１は、制御信号Ｃ５に基づき、位置検出部２０を移動させる（ステップＳ３３）。また、並行して、制御部３０は、制御信号Ｃ９をアンテナ移動部５１に送り、アンテナ移動部５１は、制御信号Ｃ９に基づき、近距離無線アンテナ５０を近距離無線アンテナ７に接近するように移動させる（ステップＳ３３）。そして、近距離無線アンテナ５０と近距離無線アンテナ７との間で近距離無線通信を行う（ステップＳ３４）。 This will be described with reference to the flowchart shown in FIG. 11A. First, when the portable wireless device 1 is placed on the placement unit 10 (step S31), the position detection unit 20 becomes portable wireless. The position of the machine 3 is detected (step S32), and control signals C2 and C4 are sent to the control unit 30. And the control part 30 which received control signals C2 and C4 sends the control signal C5 to the position detection part moving part 21, and the position detection part movement part 21 moves the position detection part 20 based on the control signal C5 ( Step S33). In parallel, the control unit 30 sends a control signal C9 to the antenna moving unit 51 so that the antenna moving unit 51 approaches the short-range wireless antenna 50 to the short-range wireless antenna 7 based on the control signal C9. Move (step S33). Then, short-range wireless communication is performed between the short-range wireless antenna 50 and the short-range wireless antenna 7 (step S34).
　このように、制御部３０が、位置検出部２０が携帯無線機３の位置を検出した後、位置検出部２０を載置部１０から遠ざけるとともに、位置検出部２０が検出した位置に基づいて、近距離無線アンテナ５０を近距離無線アンテナ７に接近させることにより、近距離無線装置１０２は、アンテナ５のアンテナ特性の劣化を抑制しつつ、近距離無線通信を効率的に行うことができる。 As described above, after the position detection unit 20 detects the position of the portable wireless device 3, the control unit 30 moves the position detection unit 20 away from the placement unit 10, and based on the position detected by the position detection unit 20. By bringing the short-range wireless antenna 50 close to the short-range wireless antenna 7, the short-range wireless device 102 can efficiently perform short-range wireless communication while suppressing deterioration of the antenna characteristics of the antenna 5.
　また、制御部３０は、近距離無線通信を実行中に携帯無線機３が変位（位置ずれ）したときに、再度、携帯無線機３の位置を検出させるようになっていてもよい。この場合、図１０の（ｂ）に示すように、近距離無線装置１０２は、携帯無線機３の変位を検出するための受信レベル検出部（変位検出手段）５２を備え得る。 Further, the control unit 30 may be configured to detect the position of the portable wireless device 3 again when the portable wireless device 3 is displaced (displacement) during the short-range wireless communication. In this case, as shown in FIG. 10B, the short-range wireless device 102 may include a reception level detection unit (displacement detection unit) 52 for detecting the displacement of the portable wireless device 3.
　近距離無線通信を実行中、受信レベル検出部５２は、近距離無線アンテナ５０における受信レベルを示す制御信号Ｃ１０を制御部３０に送る。当該受信レベルの変化は、携帯無線機３の変位の指標となるため、制御部３０は、制御信号Ｃ１０に基づいて携帯無線機３の変位を検知することができる。 During execution of short-range wireless communication, the reception level detection unit 52 sends a control signal C10 indicating a reception level at the short-range wireless antenna 50 to the control unit 30. Since the change in the reception level serves as an index of the displacement of the portable wireless device 3, the control unit 30 can detect the displacement of the portable wireless device 3 based on the control signal C10.
　そして、制御部３０は、携帯無線機３の変位を検知すると、位置検出部２０を載置部１０に接近させることを指示する制御信号Ｃ１１を位置検出部移動部２１に送る。制御信号Ｃ１１を受けて、位置検出部移動部２１は、位置検出部２０を載置部１０に接近させる。そして、位置検出部２０は、まず、携帯無線機３が載置部１０に載置されているか否かを判定する。携帯無線機３が載置部１０に載置されていれば、携帯無線機３の位置検出を行い、制御信号Ｃ２およびＣ４を制御部３０に送る。携帯無線機３が載置部１０に載置されていなければ、そのままの位置で、次回の近距離無線通信に備える。 And the control part 30 will send the control signal C11 which instruct | indicates that the position detection part 20 approaches the mounting part 10 to the position detection part moving part 21, if the displacement of the portable radio | wireless machine 3 is detected. In response to the control signal C <b> 11, the position detection unit moving unit 21 causes the position detection unit 20 to approach the placement unit 10. Then, the position detection unit 20 first determines whether or not the portable wireless device 3 is placed on the placement unit 10. If the portable wireless device 3 is placed on the placement unit 10, the position of the portable wireless device 3 is detected, and control signals C 2 and C 4 are sent to the control unit 30. If the portable wireless device 3 is not placed on the placement unit 10, the next short-range wireless communication is prepared at the same position.
　これを、図１１の（ｂ）に示すフローチャートを参照して説明すれば、まず、携帯無線機１が載置部１０に載置されると（ステップＳ４１）、位置検出部２０が、携帯無線機３の位置を検出し（ステップＳ４２）、制御信号Ｃ２およびＣ４を制御部３０に送る。そして、制御信号Ｃ２およびＣ４を受けた制御部３０は、制御信号Ｃ５を位置検出部移動部２１に送り、位置検出部移動部２１は、制御信号Ｃ５に基づき、位置検出部２０を移動させる（ステップＳ４３）。また、並行して、制御部３０は、制御信号Ｃ９をアンテナ移動部５１に送り、アンテナ移動部５１は、制御信号Ｃ９に基づき、近距離無線アンテナ５０を近距離無線アンテナ７に接近するように移動させる（ステップＳ４３）。そして、近距離無線アンテナ５０と近距離無線アンテナ７との間で近距離無線通信を行い、近距離無線通信を実行する（ステップＳ４４）。 This will be described with reference to the flowchart shown in FIG. 11B. First, when the portable wireless device 1 is placed on the placement unit 10 (step S41), the position detection unit 20 is moved to the portable wireless device. The position of the machine 3 is detected (step S42), and control signals C2 and C4 are sent to the control unit 30. And the control part 30 which received control signals C2 and C4 sends the control signal C5 to the position detection part moving part 21, and the position detection part movement part 21 moves the position detection part 20 based on the control signal C5 ( Step S43). In parallel, the control unit 30 sends a control signal C9 to the antenna moving unit 51 so that the antenna moving unit 51 approaches the short-range wireless antenna 50 to the short-range wireless antenna 7 based on the control signal C9. Move (step S43). Then, short-range wireless communication is performed between the short-range wireless antenna 50 and the short-range wireless antenna 7, and short-range wireless communication is executed (step S44).
　そして、制御部３０は、近距離無線通信が完了したかを判定し（ステップＳ４５）、近距離無線通信が完了していないときには、制御部３０は、受信レベル検出部５２からの制御信号Ｃ１０に基づいて携帯無線機３の位置ずれを判定する（ステップＳ４６）。位置ずれがなければ、ステップＳ４４に戻って近距離無線通信を継続する。一方、位置ずれがあったときには、制御部３０は、制御信号Ｃ１１を位置検出部移動部２１に送り、位置検出部移動部２１は、制御信号Ｃ１１に基づき、位置検出部２０を載置部１０に接近させる（ステップＳ４７）。 Then, the control unit 30 determines whether the short-range wireless communication is completed (step S45), and when the short-range wireless communication is not completed, the control unit 30 generates a control signal C10 from the reception level detection unit 52. Based on this, the displacement of the portable wireless device 3 is determined (step S46). If there is no position shift, the process returns to step S44 and the short-range wireless communication is continued. On the other hand, when there is a position shift, the control unit 30 sends a control signal C11 to the position detection unit moving unit 21, and the position detection unit moving unit 21 converts the position detection unit 20 into the placement unit 10 based on the control signal C11. (Step S47).
　続いて、位置検出部２０は、携帯無線機３が載置部１０に載置されているか否かを判定する（ステップＳ４８）。携帯無線機３が載置部１０に載置されていれば、ステップＳ４２に戻り、位置検出部２０は、携帯無線機３の位置検出を行う。携帯無線機３が載置部１０に載置されていなければ、位置検出部２０をそのままの位置に待機させる。 Subsequently, the position detection unit 20 determines whether or not the portable wireless device 3 is placed on the placement unit 10 (step S48). If the portable wireless device 3 is placed on the placement unit 10, the process returns to step S <b> 42, and the position detection unit 20 detects the position of the portable wireless device 3. If the portable wireless device 3 is not placed on the placement unit 10, the position detection unit 20 is made to stand by at the same position.
　このように、近距離無線通信中に、携帯無線機３の位置ずれを検出した場合、位置検出部２０を載置部１０に接近させて、位置検出を行わせることにより、位置情報を更新して、携帯無線機３の位置ずれが生じても、好適に近距離無線通信を行うことができる。 As described above, when the position shift of the portable wireless device 3 is detected during the short-range wireless communication, the position information is updated by causing the position detection unit 20 to approach the placement unit 10 to perform position detection. Thus, even if the mobile wireless device 3 is displaced, short-range wireless communication can be suitably performed.
