Abstract

본 발명은 녹음 모드 및 재생 모드를 자동으로 절환하는 하이 파이 비디오 카세트 레코더의 자동 절환 장치에 관한 것으로서, 오디오 헤드(10), 오디오헤드(10)에서 출력되는 오디오 신호를 재생하여 처리하는 오디오 신호 재생부(30), 입력 신호에 따른 구동 모드 절환 신호를 출력하는 마이콤(50), 오디오 신호를 기록할 수 있도록 처리하는 오디오 신호 기록부(40), 오디오 헤드(10)가 오디오 신호 기록부(40)에서 출력되는 오디오 신호를 자기 테이프에 기록할 수 있도록 발진 주파수를 출력하는 발진부(20)를 포함하는 하이 파이 비디오 카세트 레코더에 있어서, 마이콤(50)의 제어에 따라 스위칭되어 오디오 헤드(10)를 선택적으로 제어하는 제2스위칭부(600)를 더 포함하도록 구성하므로써, 생산 원자를 절감시킬 수 있다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic switching device of a hi-fi video cassette recorder for automatically switching between a recording mode and a playback mode, wherein an audio signal reproduction for reproducing and processing an audio signal output from the audio head 10 and the audio head 10 is performed. The unit 30, the microcomputer 50 for outputting the drive mode switching signal according to the input signal, the audio signal recording unit 40 for processing to record the audio signal, the audio head 10 in the audio signal recording unit 40 A hi-fi video cassette recorder comprising an oscillation unit 20 for outputting an oscillation frequency so that an output audio signal can be recorded on a magnetic tape, wherein the audio head 10 is selectively switched by being controlled under the control of the microcomputer 50. By further comprising the second switching unit 600 to control, it is possible to reduce the production atoms.
