Abstract

1. 청구범위 기재된 발명이 속한 기술분야1. TECHNICAL FIELD OF THE INVENTION

무선전화기에서 로우밧데리 경고음이 울린후 외부로부터 전원을 공급받아 통화상태를 지속적으로 유지하는 휴대장치에 관한 것이다.The present invention relates to a portable device that maintains a call state by receiving power from an external device after a low battery warning tone sounds in a wireless telephone.

2. 발명이 해결하고자 하는 기술적 과제2. Technical problem to be solved by the invention

통화중에 로우밧데리 경고음이 발생된 후 종지전압이 이하로 방전되면 밧데리의 전원이 차단됨으로 통화가 차단되어 밧데리 교체후 통화를 재시도 하여야 하며, 또한 통화중 로우밧데리 발생시 일정시간내에 병렬로 연결된 전화기(일반 전화기)로 통화를 계속하든지 아니면 통화를 보내야 하는 문제를 해결한다.If the battery voltage is discharged to less than the end voltage after the low battery warning tone is generated during a call, the battery is cut off and the call is cut off. Solve the problem of having to continue the call or sending a call.

3. 발명의 해결방법의 요지3. Summary of Solution to Invention

무선전화기의 휴대장치를 이용하여 통화하고 있는 상태에서 로우밧데리 경고음이 발생될 시 외부의 DC전원이 휴대장치의 전원잭으로 공급되도록 하여 통화상태가 중단되지 않고 지속적으로 유지될 수 있도록 한다.When a low battery warning tone occurs while using a portable device of a wireless telephone, external DC power is supplied to the power jack of the portable device so that the call state can be maintained without interruption.

4. 발명의 중요한 용도4. Important uses of the invention

무선전화기의 휴대장치에 적용한다.Applied to portable devices of cordless telephones.
