Abstract

본 발명은 운전자가 FM이나 AM의 방송을 찾는 도중이나 또는 라디오 방송 수신중 약전계 지역이나 타지역 이동시 메모리를 다시 시켜야 하는 경우에도 튜너를 통하여 테이프(또는 CD)를 청취할 수 있도록 하는 방송채널 선국시 테이프 청취 가능 회로에 관한 것으로 방송채널 선국등의 신호를 입력시키기 위한 키 입력부(10)와, 상기 키 입력부(10)로부터 방송선국 신호가 입력될 때 튜너(30)는 뮤트시키고 데크구동부(50)는 동작시키도록 제어를 수행하는 마이컴(20)과, 상기 마이컴(20)의 제1단자(a)로부터 출력되는 신호에 따라 스위칭되어 튜너(30)를 제어하는 제1스위칭부(40)와, 상기 마이컴(20)의 제2단자(b)로부터 출력되는 신호에 따라 스위칭되어 데크(50)를 제어하는 제2스위칭부(60)와, 상기 마이컴(20)의 제3단자(c)로부터 출력되는 신호에 따라 스위칭되어 스피커(SP)로 출력되는 오디오출력을 뮤트시키는 제3스위칭부(70)를 포함하여 이루어진다.According to the present invention, even if the driver needs to re-execute the memory while searching for a broadcast of FM or AM, or when receiving a radio broadcast, the memory needs to be replayed through a tuner. And a key input unit (10) for inputting a signal such as broadcast channel selection, and the tuner (30) mutes the deck driver (50) when a broadcast channel signal is input from the key input unit (10). ) Is switched to the microcomputer 20 to control the operation, the first switching unit 40 to control the tuner 30 is switched according to the signal output from the first terminal (a) of the microcomputer 20 and A second switching unit 60 that switches according to a signal output from the second terminal b of the microcomputer 20 to control the deck 50, and a third terminal c of the microcomputer 20 from the second switching unit 60. Is switched according to the output signal It comprises a third switching unit 70 to mute an audio output which is output to the large (SP).
