Abstract

본 발명은 곡식별기능이 구비된 오디오 카세트 플레이어에 관한 것으로, 키입력부(35); 오디오 카세트 테이프를 재생하는 데크부(31); 상기 데크(31)로부터 재생된 신호를 증폭하는 재생증폭부(38); 상기 재생증폭부(38)의 출력신호에서 곡번호를 검출하는 곡번호 검출부(37); 상기 곡번호검출부(37)의 출력을 카운트하여 해당곡의 번호를 인식하며, 상기 키입력부(35)를 통해 선곡을 위한 곡번호가 입력되면 제어신호를 발생하여 해당곡의 선두위치가 재생될 수 있도록 제어하는 마이콤(35); 상기 마이콤(35)로부터 입력된 제어신호에 따라 상기 데크의 서보를 제어하여 선곡된 곡번호의 선두부분에 재생헤드가 위치되도록 제어하는 서보제어부(36); 상기 재생증폭부(38)로부터 재생된 오디신호를 입력받아 잡음을 제거하며 음질을 보상처리한후 스피커로 출력하는 오디오처리부(39); 마이콤의 제어에 따라 곡신호를 발생하는 곡신호발생부(33); 마이콤의 제어에 따라 상기 곡번호 발생부(33)로부터 입력된 곡신호를 출력한 후 이어서 녹음을 위해 곡신호를 출력하는 녹음부(32)로 구성되어 신속하게 원하는 곡을 선곡할 수 있다.The present invention relates to an audio cassette player having a grain identification function, comprising: a key input unit 35; A deck section 31 for playing back an audio cassette tape; A reproduction amplifier section 38 for amplifying a signal reproduced from the deck 31; A song number detector (37) for detecting a song number in the output signal of the reproduction amplifier (38); By counting the output of the music number detection unit 37 to recognize the number of the corresponding song, if the song number for the selection song is input through the key input unit 35 can generate a control signal to reproduce the head position of the song A microcomputer 35 to be controlled to be; A servo controller (36) for controlling the servo of the deck according to a control signal input from the microcomputer (35) so that the playhead is positioned at the head of the tune number selected; An audio processor 39 which receives the audio signal reproduced from the reproduction amplifier 38, removes noise, compensates sound quality, and outputs the audio signal to a speaker; A tune signal generator 33 for generating a tune signal according to the control of the microcomputer; According to the control of the microcomputer is composed of a recording unit 32 for outputting the music signal input from the music number generation unit 33, and then for recording the music can quickly select the desired song.
