Abstract

본 발명은 일정공간내의 사람의 존재여부에 따라 자동으로 영상출력이 온/오프되는 텔레비젼 수상기의 영상자동 온/오프장치에 관한 것으로, 일정공간내의 사람의 존재여부를 감지하는 센서부(1), 텔레비젼 수상의 CRT로 공급되는 FBT 고압을 단속하는 스위칭 트랜지스터(Q1), 이 스위칭 트랜지스터(Q1)을 스위칭 제어하는 스위칭 구동 트랜지스터(Q2) 및, 상기 센서부(1)의 감지신호에 따라 상기 스위칭 구동 트랜지스터(Q2)의 동작을 제어하는 마이크로 컴퓨터(2)를 포함하여 구성된 것을 특징으로 한다.The present invention relates to an apparatus for automatically turning on / off an image of a television receiver in which an image output is automatically turned on / off according to the presence of a person in a certain space. The switching transistor Q1 for interrupting the FBT high voltage supplied to the CRT of the television award, the switching drive transistor Q2 for switching control of the switching transistor Q1, and the switching drive in accordance with a detection signal of the sensor unit 1. And microcomputer 2 for controlling the operation of transistor Q2.
