Abstract

본원 발명은 테이프의 재생시 원하는 구간을 반복적으로 재생하는 헤드폰 스테레오의 반복재생장치에 관한 것으로서, 키입력부와, 시스템을 제어하는 제어부와, 시스템에 공급되는 전원을 제어하는 전원제어부와, 테이프를 구동시키는 덱크어세이와, 프리앰프와, 돌비부와, 튜너부와, 상기 돌비부 및 튜너부의 신호를 선택하여 출력하는 선택증폭부와, 아날로그/디지탈 변환부와, 램(RAM)과, 디지탈/아날로그 변환부로 구성되어, 사용자에 의한 키입력부의 동작으로 반복구간을 설정하여 상기 반복구간을 램에 저장한 후 원하는 횟수만큼 텍크에 세이의 구동없이 반복재생함으로써 시간을 단축하고 잡음을 없애는 것을 특징으로 한다.The present invention relates to a repetitive playback apparatus of a headphone stereo that repeatedly plays a desired section during playback of a tape. The present invention relates to a key input unit, a control unit for controlling a system, a power control unit for controlling power supplied to a system, and a tape drive. Deck Assay, Preamplifier, Dolby Section, Tuner Section, Selective Amplification Section for Selecting and Outputting Signals of the Dolby Section and Tuner Section, Analog / Digital Converter, RAM, Digital / It is composed of an analog converter, by setting the repetition section by the operation of the key input unit by the user to save the repetition section in the RAM, it is possible to reduce the time and eliminate the noise by repeatedly playing without the drive to the text as many times as desired do.
