Abstract
팩시밀리에 있어서 전화기 사용방법에 관한 것이다. 팩시밀리에 전원이 공급될 경우 발광다이오드를 구동하고, 수광트랜지스터가 상기 발광다디오드로부터 수광시 다이알회로의 동작을 중단케 함으로써, 하나의 키패드로, 팩시밀리 전원이 켜진 상태에서는 다이알 회로의 동작이 중단되어 팩시밀리 메인 시스템에서 발생되는 다이알 신호와의 중복을 막고, 팩시밀리 전원이 꺼진 상태에서는 다이알회로를 구동시킴으로써 다이알링을 가능케 한다.A method of using a telephone in a facsimile. When power is supplied to the facsimile, the light emitting diode is driven and the light receiving transistor stops the operation of the dial circuit when receiving the light from the light emitting diode, so that the operation of the dial circuit is stopped when the facsimile power is turned on with one keypad. It prevents duplication of the dial signal generated in the facsimile main system and enables dialing by driving the dial circuit when the facsimile power is turned off.
