In the figure, reference numeral 19 denotes a fixed response message storage / reproduction circuit including a semiconductor memory. In the semiconductor memory, a response message from which a frequency component near the frequency of the CNG signal is removed is stored in advance on the manufacturer side. ..

Next, the operation of the facsimile apparatus in the above embodiment will be described.

First, prior to use, a message desired by the user is registered in the response message storage means 8. This registration is stored in the response message storage means 8 through the microphone 3 in the message registration mode.

Further, this facsimile apparatus can select the normal mode and the answering machine mode. In the normal mode, the telephone by the answering machine A and the facsimile section B are selected.
It is possible to use facsimile communication.

The case where the answering machine is selected will be described below. In the answering machine mode, the telephone line 1 is normally switched and connected to the answering machine section A side by the relay 2. Further, when an incoming call is received, it is selected whether the message registered by the user registered in the response message storage means 8 or the fixed response message stored in the semiconductor memory is transmitted as the response message. In the following description, it is assumed that the message registered in the response message storage means 8 is selected.

Now, in the answering machine mode, the incoming call detecting circuit 10 detects the calling signal and the answering machine section control means 1 is provided.
When the incoming call detection signal is output to 5, the control means 15 outputs a message sending command signal to the response message storage means 8. Then, the reply message storage means 8 reproduces and outputs the registered message and sends it to the telephone line 1 through the filter circuit 9 and the telephone circuit 5 and the relay 2. However, the response sent to the telephone line 1 The message is in a state where frequency components near the frequency of the CNG signal are suppressed by passing through the filter circuit 9.

Then, when the calling side receives the response message and sends out the CNG signal for facsimile transmission, the called side calls the telephone line 1, the relay 2 and the telephone circuit 5.
The voice / CNG detection circuit 6 detects the CNG signal sent via the. At this time, even while the response message is being sent, the frequency component near the frequency of the CNG signal in the response message is suppressed, so that the CNG signal is not canceled by the response message and the voice / C
It will be detected by the NG detection circuit 6. Therefore, the calling side does not have to wait until the end of the response message and can immediately send the CNG signal upon receiving the response message, thus saving time waste.

When the voice / CNG detection circuit 6 detects a CNG signal, the voice / CNG detection control means 18 switches the relay 2 to the side of the facsimile section B and sends it from the calling side device via the telephone line 1 and the relay 2. The received image data is received by the facsimile signal transmission / reception circuit 11 under the control of the facsimile unit control means 17, processed by the facsimile signal processing unit 12, and then printed by the printing unit 13 on the recording paper.

On the other hand, when the voice / CNG detection circuit 6 detects that a message has been sent from the calling side, the voice / CNG detection control means 18 outputs a control signal to the answering machine section control means 15. Under the control of the message recording control means 16, the message message sent from the calling side is stored in the message message storage means 7.

When the fixed response message registered in the semiconductor memory is selected as the response message, when the incoming call arrives, the fixed response message storing / reproducing circuit 19 reproduces and outputs the fixed response message, and the telephone circuit 5 And to the telephone line 1 via the relay 2. Since this fixed response message removes the frequency component near the frequency of the CNG signal at the time of registration, the CNG signal is sent while the message is being sent.
Similar to the above description, the signal can be reliably detected by the voice / CNG detection circuit 6 without being canceled by the response message. Next, FIG. 2 is a block diagram showing a facsimile apparatus according to another embodiment of the present invention, which is different from the previous embodiment in that a filter circuit 9 as a filter means is provided between an amplifier circuit 4 and a response message storage means 8. The other configuration, action, etc. are the same, except that they are inserted in.
