Abstract
본 발명은 전화선로를 이용하는 컴퓨터 및 팩시밀리의 전원자동제어장치에 관한것으로 전화선로측의 벨 신호전압을 중앙처리장치에 입력시켜 중앙처리장치를 제어하고 중앙처리장치의 출력으로 PC/FAX 전원스위치 릴레이 구동부와 전화벨신호전압스위치 릴레이구동부를 작동시켜 PC/FAX 전원스위치와 전화벨신호전압스위치를 자동으로 온, 오프시킴으로서 교신중에는 PC/FAX에 전원을 공급하고 PC/FAX를 사용하는 사람이 부재중이나 사용하지 않을 때에는 자동으로 전원이 오프되어 전력소비를 줄이고 발열로 기기가 마손되는 것을 예방토록한 것이다.The present invention relates to a computer and a facsimile power automatic control device using a telephone line. The bell signal voltage of the telephone line is input to the central processing unit to control the central processing unit and output the PC / FAX power switch relay to the central processing unit. The driver and the telephone bell signal voltage switch operate the relay driver to automatically turn on / off the PC / FAX power switch and the telephone bell signal voltage switch, so that power is supplied to the PC / FAX during communication and the person using the PC / FAX is not present or in use. When not in use, the power is automatically turned off to reduce power consumption and prevent the device from being damaged by heat.
