Description

本発明は、無線機器への給電方法に関し、特に、ホスト装置とＵＳＢ（Universal Serial Bus）を介して接続されるＵＳＢデバイスに接続された無線機器側への給電方法に関する。   The present invention relates to a method for supplying power to a wireless device, and more particularly to a method for supplying power to a wireless device connected to a USB device connected to a host device via a USB (Universal Serial Bus).

パーソナルコンピュータ（以下、「ＰＣ」という）と、マウス、モデム、ジョイスティック等の周辺機器とを接続するデータ伝送路の規格の一つとしてＵＳＢが存在する。このＵＳＢ接続では、例えば、図４に示すように、ＵＳＢホスト装置（ＰＣ）１と、ＵＳＢデバイス（プリンタ）３とをＵＳＢケーブル２を介して接続する。   USB is one of data transmission path standards for connecting a personal computer (hereinafter referred to as “PC”) and peripheral devices such as a mouse, modem, and joystick. In this USB connection, for example, as shown in FIG. 4, a USB host device (PC) 1 and a USB device (printer) 3 are connected via a USB cable 2.

また、ＵＳＢデバイス３に接続される無線機器等へ給電する際には、ＵＳＢ仕様に規定されているように、ＵＳＢホスト装置１から給電を行うこととなっている。そのため、図５に示すように、ＵＳＢ接続の無線機器（ホスト装置側）４をＵＳＢホスト装置（ＰＣ）１に接続する場合には、ＵＳＢ接続の無線機器（ホスト装置側）４への給電は可能であるが、ＵＳＢ接続の無線機器（ＵＳＢデバイス側）５をＵＳＢデバイス（プリンタ）３に接続する際には、電源ボックス７を設け、ＡＣケーブル８をコンセントに接続し、電源ケーブル６をＵＳＢ接続の無線機器（ＵＳＢデバイス側）５に接続して給電していた。   When power is supplied to a wireless device connected to the USB device 3, power is supplied from the USB host device 1 as defined in the USB specification. Therefore, as shown in FIG. 5, when a USB-connected wireless device (host device side) 4 is connected to a USB host device (PC) 1, power is supplied to the USB-connected wireless device (host device side) 4. Although it is possible, when connecting the USB-connected wireless device (USB device side) 5 to the USB device (printer) 3, a power supply box 7 is provided, the AC cable 8 is connected to an outlet, and the power cable 6 is connected to the USB. It was connected to the connected wireless device (USB device side) 5 to supply power.

例えば、特許文献１に記載のシリアル・バス・ハブを備えたモニタ・ベースは、回転自在にモニタを支持し、かつキーボード及びマウス等の周辺装置とのインターフェースのために複数のポートを有し、ＵＳＢ経由で無線周辺機器へ給電するにあって、ＵＳＢホスト装置であるモニタ・ベースから給電している。   For example, a monitor base having a serial bus hub described in Patent Document 1 supports a monitor in a rotatable manner and has a plurality of ports for interfacing with peripheral devices such as a keyboard and a mouse. When power is supplied to a wireless peripheral device via USB, power is supplied from a monitor base which is a USB host device.

しかし、上記特許文献１に記載の無線機器への給電方法等においては、ＵＳＢデバイスからの給電のルートがないため、外部電源を用いて給電する必要があった。そのため、ＵＳＢデバイスに電源ボックス等を設ける必要があった。今後、無線通信用の各種機器を、ＰＣの延長として周辺デバイスにＵＳＢ接続する場合が増加することが考えられるため、ＵＳＢデバイスに電源ボックス等を設けなくとも無線機器に給電することができれば、設備コストを低減することができるとともに、配線が簡単なものとなって便利である。   However, in the method for supplying power to the wireless device described in Patent Document 1, since there is no route for supplying power from the USB device, it is necessary to supply power using an external power source. Therefore, it is necessary to provide a power supply box or the like for the USB device. In the future, it is considered that various devices for wireless communication will be connected to peripheral devices by USB as an extension of the PC, so if power can be supplied to wireless devices without providing a power supply box etc. on the USB device, The cost can be reduced and the wiring is simple and convenient.

Power is supplied to a provided wireless device.

そして、本発明によれば、周辺デバイスに設けられた無線機器に対し、周辺デバイスの電源を介して給電するため、通常ホスト装置側から周辺デバイス側に対して給電するように構成されるシステムであっても、無線機器に対して周辺デバイスから直接給電することができ、無線機器に対する電源ボックス等を別途設けることが不要となる。   According to the present invention, in order to supply power to the wireless device provided in the peripheral device via the power supply of the peripheral device, the system is configured to supply power from the normal host device side to the peripheral device side. Even in such a case, the wireless device can be directly supplied with power from the peripheral device, and it is not necessary to separately provide a power supply box or the like for the wireless device.

前記給電方法において、前記周辺デバイスに設けられた無線機器へ前記周辺デバイスの電源を介して給電する際に、前記無線機器に設けられた電源端子を備えたプラグと、前記周辺デバイスに設けられた電源端子を備えたコネクタと、該コネクタ及びプラグを互いに接続するケーブルを介して給電するようにすることができる。これによって、１本のケーブルのみによって周辺デバイスから無線機器への給電が可能となる。   In the power feeding method, when power is supplied to a wireless device provided in the peripheral device via a power supply of the peripheral device, a plug provided with a power supply terminal provided in the wireless device, and provided in the peripheral device Power can be supplied through a connector having a power supply terminal and a cable connecting the connector and the plug to each other. Thus, power can be supplied from the peripheral device to the wireless device using only one cable.

前記給電方法において、前記ホスト装置と周辺デバイスとは、ＵＳＢ（Universal Serial Bus）を介して接続することができる。周辺デバイスからの電源供給用のケーブル及びプラグ等で給電を行うパスを設けること等により、周辺デバイスから、この周辺デバイスに設けられた無線機器への給電が可能となり、ＵＳＢホスト装置側からの給電が不要となる。   In the power feeding method, the host device and the peripheral device can be connected via a USB (Universal Serial Bus). By providing a power supply path with a power supply cable and plug from the peripheral device, power can be supplied from the peripheral device to the wireless device provided in the peripheral device, and power is supplied from the USB host device side. Is no longer necessary.

本発明によれば、無線機器を周辺デバイスにＵＳＢ接続する場合等でも、ＵＳＢデバイス側に電源ボックス等を設ける必要のない無線機器への給電方法を提供することができる。   According to the present invention, it is possible to provide a power supply method to a wireless device that does not require a power supply box or the like on the USB device side even when the wireless device is connected to a peripheral device via USB.
