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.

팩시밀리 메인시스템(100)과 키패드(200)와 다이알회로(400)를 구비한 팩시밀리 전화기에 있어서, 팩시밀리에 전원이 공급될 경우 소정상태로 발광하는 발광다이오드와, 상기 발광다이오드로부터 수광시 상기 다이알회로(400)의 동작을 중단케하는 수광트랜지스터를 구비하여 하나의 키패드로 팩시밀리 전원이 켜진상태에서는 팩시밀리 내부 회로를 이용하여 다이알링을 하고 팩시밀리 전원이 꺼진 상태에서는 전화기 최초의 다이알회로(400)를 사용하여 다이알링을 하는 것을 특징으로 하는 팩시밀리 전화기 제어회로.A facsimile telephone having a facsimile main system 100, a keypad 200, and a dial circuit 400, comprising: a light emitting diode that emits light in a predetermined state when power is supplied to the facsimile; and the dial circuit when receiving light from the light emitting diode. With a light receiving transistor that stops the operation of 400, dialing is performed using the facsimile internal circuitry when the facsimile power is turned on with one keypad, and the first dial circuit 400 of the telephone is used when the facsimile power is turned off. Fax dialing control, characterized in that for dialing. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
