제1도는 본 발명 장치에 의한 카세트 재생기의 주요부 블록구성도, 제2도는 본 발명 방법을 설명하기 위한 플로우챠우트1 is a block diagram showing the main part of a cassette player according to the present invention, and FIG. 2 is a flow chart for explaining the method of the present invention.

Claims (1)

각 기능회로를 제어하는 시스템 제어기(1)와, 데이트구동 및 음성 처리를 선택하기 위한 키 선택부(2)와, 상기 키선택부(2)의 키선택에 따라 모터(4)의 회전속도 및 방향을 제어하는 모터제어부(3)와, 헤드(5)로부터의 기록된 신호를 검출 증폭시키는 증폭기(6)와, 음량 및 음질상태를 조정하는 음량 및 음질 조저어부(7)와 스피커 또는 헤드폰(9)으로 출력시키기 위한 음성신호를 증폭시키는 음성증폭기(8)로 된 것에 있어서, 상기 증폭기(6)로 부터 출력되는 음성신호에 무음구간을 검출하기 위해 레벨증폭시키는 버퍼(10)와, 상기 버퍼(10)로 부터의 음성 출력을 평활시키는 저역통과필터(11)에 의해 직류화 시키고 직류화된 신호를 기준전압 설정부(13)의 기준전압과 비교하여 무음부를 판별하는 비교기(12)와, 구간반복재생을 선택하기 위한 구간반복 재생키를 구비하여 구간반복 재생키 신호가 입력되면 시스템 제어기가 음소거시킴과 동시에 무음부 구간이 검출될때까지 되감기를 수행하고, 되감기 수행중에 무음부구간이 검출되면 되감기 모드를 정지시킴과 동시에 음소거 해제 및 재생 동작이 이루어지게 함을 특징으로 하는 단일키에 의한 테이프 구간 반복 재생제어장치.A system controller 1 for controlling each function circuit, a key selector 2 for selecting date driving and voice processing, a rotational speed of the motor 4 according to the key selection of the key selector 2, and The motor control unit 3 for controlling the direction, the amplifier 6 for detecting and amplifying the recorded signal from the head 5, the volume and sound quality control unit 7 for adjusting the volume and sound quality state, the speaker or the headphone ( 9) A voice amplifier 8 for amplifying a voice signal for output to a buffer, comprising: a buffer 10 for level-amplifying the voice signal output from the amplifier 6 to detect a silent section; and the buffer A comparator 12 which directs the DC signal by a low pass filter 11 for smoothing the audio output from 10 and compares the DC signal with a reference voltage of the reference voltage setting unit 13 to determine a silent part; Obtain the interval repeat play key to select the interval repeat play. In comparison, when the section repeat play key signal is input, the system controller mutes the sound and rewinds until the silent section is detected. Tape section repeat playback control device by a single key characterized in that made. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
