Abstract

본 발명은 비디오테이프 재생속도 제어장치에 관한 것으로, 영상신호와 음성신호가 기록된 비디오테이프를 구동하는 테이프구동수단을 구비한 비디오테이프레코더에 있어서, 미리 정해진 재생속도에 의한 비디오테이프의 재생을 제어하는 리모콘과, 상기 리모콘에 의해 비디오테이프의 재생이 제어된 상태에서 시청자를 검출하는 시청자검출센서, 상기 시청자검출센서에 의해 시청자가 검출되지 않는 시간적인 기준치를 카운트하는 타이머, 상기 타이머에 의해 시간적인 기준치 동안 상기 시청자검출센서에 의해 시청자가 검출되지 않는 경우 상기 테이프구동수단에 의한 상기 비디오테이프의 재생속도를 변경하는 제어수단을 구비하여 구성되고, 상기 제어수단은 상기 재생속도가 변경된 상태에서 상기 시청자검출센서에 의해 시청자가 검출되면 상기 테이프구동수단에 의한 상기 비디오테이프의 재생속도를 원래의 속도로 회복시키도록 된 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a videotape playback speed control apparatus, comprising: a videotape recorder having tape driving means for driving a videotape on which video and audio signals are recorded; A remote control unit, a viewer detection sensor for detecting a viewer while the playback of the videotape is controlled by the remote control, a timer for counting a temporal reference value at which the viewer is not detected by the viewer detection sensor, and a temporal And a control means for changing the playback speed of the video tape by the tape driving means when the viewer is not detected by the viewer detection sensor during the reference value, wherein the control means is configured to change the viewer in the state where the playback speed is changed. When the viewer is detected by the detection sensor Is a so as to restore the play speed of the video tape by the tape driving unit group to the original speed.
