以下、本発明を具体化した一実施形態を図面に従って説明する。
図１は、本実施形態の非接触充電システムを示す。デジタルカメラ等よりなる携帯機器１０は、静止画や動画の撮影等、主たる機能を実行するための機能回路（図示略）を備え、同じく内蔵の二次電池（バッテリ）１１からの電源供給に基づいて動作する。受電側回路１２は、電力用コイル１３を通じて受電した充電器２０からの所定の交流電力に基づいて所定の直流電力に変換するものであり、二次電池１１はその直流電力にて充電される。また、携帯機器１０は認証回路１４を備えており、該認証回路１４は認証用コイル１５を通じて充電器２０との間で確認信号の授受を行う。 DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, an embodiment of the invention will be described with reference to the drawings.
FIG. 1 shows a contactless charging system according to this embodiment. The portable device 10 including a digital camera or the like includes a functional circuit (not shown) for executing main functions such as shooting of still images and moving images, and is also based on power supply from a built-in secondary battery (battery) 11. Works. The power receiving side circuit 12 converts to predetermined DC power based on predetermined AC power from the charger 20 received through the power coil 13, and the secondary battery 11 is charged with the DC power. In addition, the mobile device 10 includes an authentication circuit 14, and the authentication circuit 14 exchanges a confirmation signal with the charger 20 through the authentication coil 15.

充電器２０は、外部からの例えば商用電源の供給に基づいて携帯機器１０の充電に適した所定の交流電力を生成する送電側回路２１を備え、該送電側回路２１は電力用コイル２２を通じて携帯機器１０の電力用コイル１３に向けて電力伝送を行う。また、充電器２０においても認証回路２３を備えており、該認証回路２３は認証用コイル２４を通じて携帯機器１０側の認証回路１４との間で確認信号の授受を行う。   The charger 20 includes a power transmission side circuit 21 that generates predetermined AC power suitable for charging the portable device 10 based on, for example, supply of commercial power from the outside. The power transmission side circuit 21 is carried through the power coil 22. Power transmission is performed toward the power coil 13 of the device 10. The charger 20 also includes an authentication circuit 23, which transmits and receives a confirmation signal to and from the authentication circuit 14 on the mobile device 10 side through the authentication coil 24.

つまり、充電器２０に載置（近接）したものが該充電器２０と適合する携帯機器１０か否かをその確認信号の授受にて判定し、適合の携帯機器１０であるとの判定に基づいて送電側回路２１に充電許可信号を出力し、該送電側回路２１はその充電許可信号の入力に基づいて携帯機器１０に向けての送電を開始するようになっている。これにより、適合しない携帯機器や金属等が充電器２０に載置されても送電が実施されないため、無用な充電動作が防止される。   That is, it is determined whether or not the portable device 10 that is placed (close to) the charger 20 is compatible with the charger 20 by transmitting and receiving the confirmation signal, and based on the determination that the portable device 10 is compatible. Then, a charging permission signal is output to the power transmission side circuit 21, and the power transmission side circuit 21 starts power transmission toward the mobile device 10 based on the input of the charging permission signal. Thereby, even if an incompatible mobile device, metal, or the like is placed on the charger 20, power transmission is not performed, so unnecessary charging operation is prevented.

ここで、携帯機器１０の電力用及び認証用の両コイル１３，１５の構成について、図２に示すように、携帯機器１０内において略正方形状に設定されるコイル配置領域Ａ１には、円環状に巻回される１個の電力用コイル１３に対し、４個に分割構成されそれぞれ円環状に巻回された認証用コイル１５が同一平面上に配置されている。電力用コイル１３はコイル配置領域Ａ１の中央部に配置され、扱う電力の小さい認証用コイル１５は電力用コイル１３よりも小径で構成され、コイル配置領域Ａ１の四隅にそれぞれ配置されている。充電器２０側の電力用及び認証用の両コイル２２，２４も先の携帯機器１０側と同様に構成されている。   Here, regarding the configuration of both the power and authentication coils 13 and 15 of the portable device 10, as shown in FIG. 2, the coil arrangement region A <b> 1 set in a substantially square shape in the portable device 10 has an annular shape. An authentication coil 15 that is divided into four parts and wound in an annular shape is arranged on the same plane with respect to one power coil 13 wound around the power coil 13. The power coil 13 is arranged at the center of the coil arrangement area A1, and the authentication coil 15 with a small amount of power to be handled has a smaller diameter than the power coil 13, and is arranged at each of the four corners of the coil arrangement area A1. Both the power and authentication coils 22 and 24 on the charger 20 side are configured in the same manner as the previous portable device 10 side.

このように本実施形態の電力用及び認証用の両コイル１３，１５（２２，２４）においては、コイル配置領域Ａ１の利用効率を高く構成しているため、電力用及び認証用コイル１３，１５（２２，２４）をコンパクトな構成とでき、携帯機器１０及び充電器２０の小型化に寄与する構成となっている。   As described above, in the power and authentication coils 13 and 15 (22 and 24) of the present embodiment, the utilization efficiency of the coil arrangement area A1 is configured to be high, so that the power and authentication coils 13 and 15 are configured. (22, 24) can be made into a compact configuration, which contributes to downsizing of the portable device 10 and the charger 20.

次に、本実施形態の特徴的な作用効果を記載する。
（１）本実施形態では、電力用コイル１３，２２と同一平面において、４個に分割し小径で構成した認証用コイル１５，２４がその電力用コイル１３，２２の周囲にそれぞれ配置されている。つまり、電力用コイル１３，２２の周囲の領域を認証用コイル１５，２４の配置に効率よく利用することで、電力用及び認証用コイル１３，１５（２２，２４）をコンパクトな構成とでき、搭載する携帯機器１０及び充電器２０の小型化に寄与することができる。 Next, characteristic effects of the present embodiment will be described.
(1) In the present embodiment, authentication coils 15 and 24 that are divided into four parts and have a small diameter are arranged around the power coils 13 and 22 in the same plane as the power coils 13 and 22, respectively. . In other words, by efficiently using the area around the power coils 13 and 22 for the arrangement of the authentication coils 15 and 24, the power and authentication coils 13 and 15 (22 and 24) can be made compact. This can contribute to miniaturization of the portable device 10 and the charger 20 to be mounted.

（２）本実施形態のように略正方形状（略矩形状）のコイル配置領域Ａ１を設定する場合、このコイル配置領域Ａ１の中央部に１個の電力用コイル１３，２２を配置し、認証用コイル１５，２４がコイル配置領域Ａ１の角部に分割配置されている。つまり、円環状に巻回される電力用コイル１３，２２に対してはコイル配置領域Ａ１の角部が大きく空くため、そこに認証用コイル１５，２４を配置することでコイル配置領域Ａ１の利用効率は高く、特に四隅全部に配置する本実施形態では利用効率は一層高く、電力用及び認証用コイル１３，１５（２２，２４）のコンパクトな構成を確実としている。   (2) When a substantially square (substantially rectangular) coil arrangement area A1 is set as in the present embodiment, one power coil 13, 22 is arranged in the center of the coil arrangement area A1, and authentication is performed. The coils 15 and 24 for use are divided and arranged at the corners of the coil arrangement region A1. In other words, since the corners of the coil arrangement area A1 are large for the power coils 13 and 22 wound in an annular shape, the use of the coil arrangement area A1 is provided by arranging the authentication coils 15 and 24 there. The efficiency is high, and in particular, the use efficiency is higher in this embodiment arranged at all four corners, and the compact configuration of the power and authentication coils 13 and 15 (22, 24) is ensured.

尚、本発明の実施形態は、以下のように変更してもよい。
・上記実施形態では、電力用コイル１３，２２と認証用コイル１５，２４の両者ともに円環状に構成したが、楕円、四角形、三角形等の環状に構成してもよく、また電力用コイル１３，２２と認証用コイル１５，２４とで異なる環状形状として適宜組み合わせてもよい。 In addition, you may change embodiment of this invention as follows.
In the above embodiment, both the power coils 13 and 22 and the authentication coils 15 and 24 are configured in an annular shape, but may be configured in an annular shape such as an ellipse, a quadrangle, and a triangle. 22 and the authentication coils 15 and 24 may be appropriately combined as different annular shapes.

Moreover, as shown in FIG. 3, the power coils 13 and 22 may be divided into two pieces and configured in an elliptical annular shape that is short in the juxtaposition direction. In this case, even when the power coils 13 and 22 are divided, the increase in size in the parallel arrangement direction can be suppressed. Further, for such power coils 13 and 22, authentication coils 15 and 24 divided into six are arranged between the four corners of the coil arrangement region A1 and the longitudinal ends of the power coils 13 and 22.

That is, in addition to the authentication coils 15 and 24 being arranged on the outer peripheral side of the power coils 13 and 22, the region on the inner peripheral side of the power coils 13 and 22 is also used for the arrangement of the authentication coils 15 and 24. . Even if it does in this way, the utilization efficiency of the circumference | surroundings area | region of the coil for electric power can be improved, and it can contribute to the compact structure of the coils 13 and 15 for electric power and authentication (22, 24). The authentication coils 15 and 24 divided into the outer side and the inner side may be connected to each other or may be used separately.

また図４（ａ）のように、電力用及び認証用コイル１３，１５（２２，２４）の巻回形状を同心の円環状とし、また図４（ｂ）のように同心の四角環状とすることで、コイル１３，１５（２２，２４）間の隙間を極めて小とできるため、電力用コイル１３，２２の周囲領域の利用効率向上を確実としている。   Further, as shown in FIG. 4A, the winding shape of the power and authentication coils 13, 15 (22, 24) is a concentric annular shape, and as shown in FIG. Thus, since the gap between the coils 13 and 15 (22, 24) can be made extremely small, the utilization efficiency of the surrounding area of the power coils 13 and 22 is ensured.
