Abstract

본 발명은 인체 유무 감지용 시청자의 존재 유무를 판단함으로써 VCR의 재생 모드를 자동으로 정지 모드로 전환시켜 주는 장치에 관한 것이다.The present invention relates to a device for automatically switching the playback mode of the VCR to the stop mode by determining the presence or absence of a viewer for detecting the presence or absence of a human body.

본 발명에 따른 VCR의 작동 모드 자동 전환장치는 일정 거리이내의 인체에서 발산되는 체온을 감지하는 인체 유무 감지용 적외선 센서(10)와, 이 센서로부터 감지된 신호를 비교 전압으로서 기준 전압과 비교하여 인체 유무 검출신호를 발생하는 비교기(18)와 비교기(18)의 출력에 따라 시청자의 부재시 재생 모드를 정지 모드로 전환시키고, 시청자 존재시 정지 모드를 재생 모드로 전환시켜 주는 마이컴(20)을 포함한다.The automatic switching mode of the operation mode of the VCR according to the present invention includes an infrared sensor 10 for detecting the presence or absence of a body temperature emitted by the human body within a certain distance, and comparing the signal detected from the sensor with a reference voltage as a comparison voltage. Comparator 18 for generating a human presence detection signal and the microcomputer 20 to switch the playback mode in the absence of the viewer to the stop mode in accordance with the output of the comparator 18, and to switch the stop mode to the playback mode in the presence of the viewer do.
