Claims (2)

In a circuit that allows remote control of the entire system of the facsimile as intended by the user through the telephone 10 on the same telephone line installed far from the facsimile body; A relay means (1) connected to a telephone line and controlling a loop connection through switch switching, a transformer (2) connected to the relay means, and an amplification means connected to the transformer to amplify a signal of the line ( 3) Tone and DTMF detection means 4 connected to the amplification means, off-hoop detection means 5 and ring detection means 6 connected to the remote telephone line 10 to detect respective signals, and the off Input / output buffer means 7 connected to hook detection means and ring detection means, CPU 8 connected to the tone and DTMF detection means 4 and input / output buffer means 7, and ROM connected to the COU ( 9) A facsimile remote control circuit, characterized in that consisting of. A relay means (1) connected to a telephone line and controlling a loop connection through switch switching, a transformer (2) connected to the relay means, and an amplification means (3) connected to the transformer to amplify a signal of a line (3) ), A tone and DTMF detecting means 4 connected to the amplifying means, an off hook detecting means 5 and a ring detecting means 6 connected to the remote telephone line 10 to detect respective signals, and the off hook. Input / output buffer means 7 connected to the detection means and the ring detection means, CPU 8 connected to the tone and DTMF detection means 4 and input / output buffer means 7, and ROM 9 connected to the CPU. In the method of embedding a facsimile remote control circuit consisting of a) into the facsimile body and remote control via the telephone 10 of the remote place; The first step of setting the facsimile to the telephone mode (101), the second step of continuously detecting the input of the ring signal (102, 103), the state of the remote telephone 10 is checked (104) if the on-hook state Repeating the second step and turning off the relay (1) to facsimile (105), if the off-hook state (106, 108) or the corresponding function is performed (106, 108) depending on whether or not a specific DTMF tone is detected (107, 108). 109) In the fourth step, the state of the remote keeper telephone 10 is checked (110). If the off-hook state is repeated, the fourth step is repeated, and if the on-hook state, the fax is separated from the telephone line through the relay (1). 111) A fax remote control method, characterized in that performed by the fifth step. ※ Note: The disclosure is based on the initial application.
