Claims (1)

파워키이의 온/오프 신호에 따라 시스템의 전원을 온/오프시키고, 소정의 키이 입력신호에 따라 시스템의 동작을 제어하는 마이컴을 구비한 전자기기의 전원제어회로에 있어서; 파워키이 입력시 파워키이가 온 또는 오프됨과 동시에 소정시간동안 타이머 동작을 하여 타이머 동작이 완료되기 전에 다시 파워키이 입력이 있을경우 입력 신호를 차단하여 상기의 마이컴의 전원 온/오프동작에 영향을 미치지 않게 하고, 타이머 동작이 완료된후 파워키이 입력이 있을 경우 상기 마이컴 파워키이 온/오프신호가 입력되게 하여 시스템의 전원을 온 또는 오프시키기 위한 제어부를 포함함을 특징으로 하는 전자기기의 전원 제어회로.A power supply control circuit of an electronic apparatus having a microcomputer for turning on / off a power supply of a system in accordance with an on / off signal of a power key and controlling operation of the system according to a predetermined key input signal; When the power key is turned on or off, at the same time the timer is operated for a predetermined time and if the power key is input again before the timer is completed, the input signal is cut off to affect the power on / off operation of the microcomputer. And a control unit for turning on / off the power of the system by inputting the on / off signal to the microcomputer power key when the power key is input after the timer operation is completed. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
