Abstract

본 발명은 무선전화기에 관한 것으로, 정전시에도 무선 전화기 고장장치에 전원을 공급하여 통과할 수 있도록 한 무선전화기의 전원공급방법 및 장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wireless telephone, and more particularly, to a power supplying method and apparatus for supplying power to a wireless telephone failure apparatus in the event of a power failure.

본 발명은 비정전시 별도의 배터리에 전원을 충전하고 정전시 배터리에 충전된 전원을 무선전화기 고정장치측으로 공급하므로, 정전시에도 통화가능하게 되어 무선전화기 사용상의 편리성을 대폭 증가시킬 수 있다.The present invention charges power to a separate battery during non-outage and supplies power charged to the battery to the radiotelephone fixed device during power outage, thereby making it possible to make a call during a power outage, thereby greatly increasing convenience in using a radiotelephone.
