In addition, C1 and C2 are capacitors for carting the DC voltage superimposed on the telephone line 10, RET is a cold current line ring for capturing the line when the relay connects the telephone line IO to the modem device side, and TI , T2 is an audio transformer.

FIG. 3 is a flowchart showing the operation of the central control means 8, which flow is stored in the program memory of the computer of the central control means 8.

Hereinafter, the operation of the apparatus shown in FIGS. 1 and 2 will be explained based on the flowchart shown in FIG.

First, in step S1, when the operator sets a document on the reading means 6 and makes a manual call using the telephone 9,
In S2, a dial tone signal is input to the dial tone detection means 13, and a dial numeric signal is input from the dial tone detection means 13 to the dial memory built in the central control means 8 via the signal line 1-b. Ru. In addition, when making a manual call in step Sl, telephone line 1
o is connected by a relay 11 to the telephone side of the signal lines 11-a and 11-b.

Next, in S3, the telephone number manually called by the operator in step Sl is registered in the telephone number registration memory built in the central control means 8, in which several frequently used telephone numbers can be registered in advance. If the phone number is
When the automatic number confirmation switch on the operation panel of
A confirmation display command code is output to the display means 5 via the signal line 5-a, a confirmation display is displayed on the display panel of the display means 5, and the process proceeds to S6. Also, the manual calling telephone number must be a registered number. If so, the process proceeds to S12, where the central control means 8 outputs a number error display command code to the display means 5 via the signal line 5-a, a number error is displayed on the display panel of the display means 5, and the process returns to step 31. It turns out.

If the automatic number confirmation switch is off in S3, the process proceeds to S4, in which the central control means 8 outputs the previously manually dialed number signal to the display means 5 via the signal line 5-a and displays it. The dial number is displayed on the display panel of the means 5, and the process advances to S5.

In S5, the operator confirms the dial digits displayed on the display means 5, and also confirms the ringing tone from the other party's telephone, and if the other party's telephone is busy, the operator displays the dial number displayed on the display means 5, and if the other party's telephone is busy, the operator displays the dial number displayed on the display means 5. When the above automatic transmission switch is turned on, the calling operation is automatically repeated until the busy mode ends and the telephone line 10 is connected to the other party's telephone.

Therefore, the operator does not need to make a manual call again, which simplifies the operation.

Next, in S6, the central control means 8 determines whether the automatic transmission switch is on or off. If it is off, the process proceeds to S7, and in S7, the operator
When the send button on the operation panel is pressed, the process proceeds to 88, where the central control means 8 outputs a relay switching command code to the relay 11 via the signal line 1-d, and the relay 11 connects the telephone line 10 to the connection line 11-d. c, the modem means side of 11-d is switched, and the process proceeds to S8. At S8, facsimile communication is performed by the central controller 13) 8, the reading means 6, the coding means 3, and the modem means 2, and the image signal of the original set in the reading means 6 is transmitted, and the process proceeds to SlO.
When the central control means 8 confirms the completion of transmission, 311
Then, in the Sll, the central control means 8 outputs the telephone line release command code to the relay 1 via the signal line 1-d, and after the telephone line IO is once released by the relay 11, it is sent to the telephone side. Connected.

If the automatic transmission switch is turned on in S6, the process proceeds to S15, and in S15, a ringing signal is detected. If the signal returned from the other party's telephone is a ringing signal, the ringing signal detection means signal fi by 14
t-c is set to H level, and if it is not a calling signal, it is set to L level by the calling signal detection means 14, so the central control means 8 determines whether the signal line 1-c is at H level or L level. If it is determined whether there is a call signal, it is determined whether it is a call signal or not.

If it is not a call signal in S15, the process advances to 516;
In step 318, the telephone line IO is once released by the operation described in step Sll, and then connected to the telephone side, and St? Proceed to. 31? At this point, a time waiting program is set in the computer of the central control means 8, and after waiting for a certain period of time, the process proceeds to step 318, where the central control means 8 issues a call via the dial digit signal 1% and 1-a. The calling means 12 performs a calling operation and returns to step S15 to detect whether it is a calling signal.However, steps S15, S1B, and S17.518 are performed until a calling signal is detected. The action is repeated.

Further, when a calling signal is detected in step 315, the process proceeds to S8, Sθ, S10, and 311, and the transmission ends.

By registering the other party's telephone number in the facsimile machine in advance, turning on the automatic number confirmation switch, and turning on the automatic transmission switch, the operator can simply make a manual call using the telephone and the rest will be done automatically. The facsimile machine automatically checks the number and sends it, making the operation extremely simple.

[Effect] As explained above, by providing the image communication device with a means for recognizing the communication transmission signal, there is an effect that image communication is no longer performed to a wrong communication destination.
