Abstract

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

비디오 장치의 전원공급 회로에 있어서, 특히 비디오 전원 차단모드(대기상태)시 공급하던 전원을 제어하여 소비 전력을 감소시키는 회로 및 그 제어방법에 관한 것이다.A power supply circuit of a video apparatus, and more particularly, relates to a circuit for controlling power supplied in a video power off mode (standby state) to reduce power consumption and a control method thereof.

2. 발명이 해결하려고 하는 기술적 과제2. The technical problem to be solved by the invention

종래의 비디오데크 장치는 전원차단모드(대기상태)에서도 항시 테이프상태 체크 센서들에 전원을 공급해 주어야 했기 때문에 실제 35미리암페어에서 80미리암페어까지의 전류를 소모시켰던 문제점을 해결한다.The conventional video deck device solves the problem of consuming a current of 35 to 80 mA since the tape status check sensors had to be supplied at all times even in the power-off mode (standby state).

3. 발명의 해결방법의 요지3. Summary of Solution to Invention

비디오장치의 전원차단모드(대기상태)에서 테이프를 삽입 할 때만 센서를 동작시킬 수 있도록 전원공급을 제어하는 방법 및 회로를 제공한다.Provided are a method and a circuit for controlling a power supply so that a sensor can be operated only when a tape is inserted in a video power off mode (standby state).

4. 발명의 중요한 용도4. Important uses of the invention
