【発明の詳細な説明】
本発明は宅内の加入者線を無線回線に置き換えることに
よって電話機設置場所を固定することなく、持ち運びを
可能とするようなコードレス電話における電源供給方法
に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a power supply method for a cordless telephone that replaces a subscriber line in a home with a wireless line, thereby making it possible to carry the telephone without fixing its installation location.
図は本発明の対象とするシステムの説明図であり、図に
おいて１が宅内の親局、２が子局であり、親局には加入
者線が繋がれ親局と子局とは無線回線によって繋がれて
いる。The figure is an explanatory diagram of the system to which the present invention is applied. In the figure, 1 is a master station in the home, and 2 is a slave station. A subscriber line is connected to the master station, and the master station and slave stations are connected to a wireless line. are connected by.
従って子局２は宅内において自由に持ち運び可能となり
特に宅内をオフィス等の机等の移動がひんばんな場所に
おいて特に便利なシステムとなる。Therefore, the slave station 2 can be freely carried around the house, making the system particularly convenient in places such as offices where it is difficult to move desks around the house.
図で子局２は１つの場合を想定しているが本発明はかか
るシステムに限定されず子局が複数であっても伺らさし
つかえない。Although the figure assumes a case where there is only one slave station 2, the present invention is not limited to such a system, and can also be used even if there is a plurality of slave stations.
また図において、親局１の無線機はそれが固定されてい

テリ等の直流電源によって電源が供給されることが必須
である。In addition, in the figure, since the radio of master station 1 is fixed, it is convenient to be powered by a commercial power source, and slave station 2 is configured to be mobile, so it is convenient to use a DC power source such as a battery. It is essential that power be provided by a power source.
そして本発明はかかる点に鑑みてなされたものであり、
その構成は宅内の加入者線が無線回線で構成されたコー
ドレス電話機において、充電可能な直流電源が親局で常

充電源とし、且つ停電時親局の電源となるように構成し
たことを特徴とするものである。The present invention has been made in view of this point,
The configuration is that in a cordless telephone whose subscriber line in the house is a wireless line, a rechargeable DC power supply is constantly charged at the master station, and the DC power supply serves as a supplementary power source when the DC power supply of the slave station is discharged. It is characterized by being configured to serve as a power source for the master station during a power outage.
次に本発明の実施例について説明すると親局１には充電
可能な直流電源が備えられ、常時充電されており、親局
１内の無線機への電源は商用電源から与えられるが停電
時該充電されている直流電源が切換り接続され親局１の
無線機の電源となるよう構成される。Next, an embodiment of the present invention will be described. The master station 1 is equipped with a rechargeable DC power source and is constantly charged. Power to the wireless device in the master station 1 is supplied from the commercial power supply, but when a power outage occurs, The charged DC power source is switched and connected to serve as a power source for the wireless device of the master station 1.
かかる切換接続の電気回路の構成は当業者であれば種々
設計変更可能であるので、その詳細は省略する。Since those skilled in the art can make various design changes to the configuration of the electrical circuit for switching and connecting, the details thereof will be omitted.
一方、子局２にはバッテリーが備えられ直流電流を供給
している。On the other hand, the slave station 2 is equipped with a battery and supplies direct current.
従ってこの備えられたバッテリが放電した場合には親局
１で充電されている直流電源を使用することにより常時
通話が可能である。Therefore, even if the provided battery is discharged, by using the DC power source charged in the master station 1, it is possible to talk at all times.
なお、この子局２に備えられるバッテリが充電可能なも
のであれば親局１で充電された直流電源を使用する際、
親局１で子局２に備えられたノ、クツテリを充電するよ
うにすれば一層システムの運用上効果を有するものとな
る。In addition, if the battery provided in this slave station 2 is rechargeable, when using the DC power supply charged in the master station 1,
If the main station 1 charges the battery provided in the slave station 2, the system will be more effective in operation.
