る。2. Description of the Related Art Conventionally, an operator picks up the handset of a slave telephone of a facsimile machine, listens to the signal transmitted over the line, and when the operator determines that a facsimile reception has been received, the operator sends a DTMF signal from the slave telephone to the main facsimile machine.
The main facsimile device is configured to initiate reception by sending a (dual tone multi-frequency) signal or by switching the slave telephone.

ングが異なる場合などリモート受信されない。However, the above-mentioned conventional example has the following drawbacks due to the operation timing of the operator who performs the remote reception operation on the facsimile machine. (1) In the method of transmitting a DTMF signal from a slave phone and determining the DTMF signal using the main facsimile device, remote reception may not be possible due to the length of the DTMF signal transmission time and the signal interval of the DTMF signal operated by the operator. (2) In the method in which the main facsimile device determines the switch of the sub phone by switching the hook switch of the handset of the sub phone from off to on, the operation timing of the operator on the sub phone side and the reception timing determined on the main unit side are different. etc. remote reception is not possible.

ある。[Means for Solving the Problems] According to the present invention, in order to perform remote reception from a slave telephone to the main body facsimile device, the main body facsimile device detects that the handset of the connected telephone is off-hook, and when the connected telephone is off-hook. To, C
By operating the detection process of the NG (calling tone) signal, the operator's operation is simplified and the main facsimile device can smoothly enter the receiving state.

有する。Reference numeral 7 denotes a modem, which also includes a clock generation circuit and the like. Modem 7 is controlled by CPU 1.
Modulate the transmission data stored in AM3 and send it to NCU8
to line 9 via. Further, the modem 7 demodulates the received data and stores the binarized data in the RAM 3. Further, during the reception operation, it identifies the DTMF signal sent from the other party, evolves the data into 16, and stores it in the RAM 3. 8
is an NCU (line control unit), which has a function of switching and connecting the telephone line 9 to either the modem 7 or the connection telephone 10, or both at the same time under the control of the CPU 1. The NCU 8 also has a function of detecting off-hook of the connected telephone 10.

プＳ５）、スタンバイ状態に戻る。When a Ci (calling) signal is received on the line shown in FIG. 1, the Ci signal is directly transmitted to the connecting telephone (child telephone) 10 via the NCU 8. When the CPU 1 detects off-hook of the connected telephone (child telephone) 10 by the NCU 8 (step S1), the CPU 1 detects a CNG signal by the modem 7 of the main body facsimile device via the NCU 8 (step S2). If no CNG signal is detected, the telephone communication state (step S4) is changed to the slave telephone on-hook (step S5), and the telephone returns to the standby state.
