디지탈 오디오테이프 레코더의 전원차단시 모드변환회로에 있어서, 전원차단시, 로딩모터가 구동될 수 있도록 백업전원을 공급하기 위한 전원백업회로(10)와, 데크의 현재모드를 판정하여 정지모드 이외의 가타모드에서는 모터구동회로(8)의 한 입력단자에 하이신호를 출력하고 모터구동회로(8)의 다른 한 입력단자에는 그라운드 신호가 입력되게 하는 스위칭 및 게이트회로(20)와, 데크가 정지모드인지 아닌지를 판정하여 R/S 플립플롭(1)의 입력제어신호를 출력하는 제어부(30)와, 상기 스위칭 및 게이트회로(20)의 출력신호에 의하여 로딩모터를 구동하거나 정지시키는 모터구동부(40)로 이루어진 것을 특징으로 하는 디지탈 오디오테이프 레코더의 전원차단시 모드변환회로.In the mode switching circuit of the digital audio tape recorder when the power is turned off, a power backup circuit 10 for supplying backup power so that the loading motor can be driven when the power is turned off, and the current mode of the deck is determined to determine the mode other than the stop mode. In other mode, the switching and gate circuit 20 outputs a high signal to one input terminal of the motor driving circuit 8 and a ground signal is input to the other input terminal of the motor driving circuit 8, and the deck is in a stop mode. The controller 30 outputs an input control signal of the R / S flip-flop 1 by determining whether or not, and a motor driver 40 which drives or stops the loading motor according to the output signal of the switching and gate circuit 20. Mode conversion circuit when the power supply of the digital audio tape recorder, characterized in that consisting of. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
