BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control system for a facsimile machine.

[0002]

2. Description of the Related Art Facsimile apparatuses have been widely used as apparatuses for transmitting and receiving images or documents. In recent years, an increasing number of devices have been miniaturized so that they can be used in general households and are integrated with a telephone in order to use one telephone line for both facsimile communication and voice communication.

In such an apparatus, various functions are added to satisfy not only the function as a facsimile machine but also the function as a telephone. For example, one of the features
One is the so-called speakerphone function, which allows you to talk to the other party without using a handset. With this speakerphone function, the voice of the called terminal input from the telephone line is output from the speaker unit of the device through the loudspeaker amplifier, and the voice of the user is sent to the called terminal through the telephone line through the microphone. ..

When dialing using the speakerphone function, the speakerphone is turned on from the operation unit. Then, the dial tone input from the telephone line is output from the speaker.

Next, when the dial button is pressed from the operation section, the mute function of the mute function is muted to the microphone so that noise does not occur in the dial signal, and the dial signal is sent to the telephone line. After a certain period of time has passed since the dial signal was sent, the microphone is unmuted, and if the other party hears the voice, you can talk as it is. By pressing the button, the document set on the document table is read and transmitted as a facsimile signal to the other side.

[0006]

However, in the above-mentioned configuration, when the other party's response is voice, the mute of the microphone is canceled after the dial signal is sent out so that the other party can immediately enter the call. The input ambient sound wraps around to the receiving side as sidetone, and even if a facsimile signal is input from the other party, it cannot be detected,
After dialing, there was a problem that even if a facsimile signal was input from the other side, it could not be automatically switched to facsimile communication.

The present invention has been made in view of the above-mentioned prior art. In a facsimile apparatus having a speakerphone function, a calling terminal is a facsimile apparatus after a manual call is made (a dial is made as the user inputs). Yes CN sent back from the called terminal when a signal indicating that there is an intention to send (hereinafter referred to as CNG signal) is sent to the called terminal
To provide a control method of a facsimile device that facilitates detection of a response signal by not canceling mute applied to a microphone when detecting a response signal to a G signal and can automatically move to a facsimile operation. Is.

[0008]

SUMMARY OF THE INVENTION The present invention comprises a response signal detecting means for detecting a response signal returned from a called terminal,
Dialing means for dialing the called terminal, speakerphone means for making a call with the called terminal, mute means for performing mute processing on the microphone, and transmission document detecting means for detecting the presence or absence of a document to be transmitted to the called terminal. In the facsimile apparatus including the above, when the response signal is detected by the response signal detecting means, the mute means of the microphone is not released if the transmission original detecting means determines that the transmission original exists.

[0009]

According to the present invention, when a call is manually made using the speakerphone function and the transmission document detecting means determines that there is a transmission document, the microphone mute is not released after dialing, and the CNG is not released. After transmitting the CNG signal from the signal transmitting means to the called terminal, the response signal detecting means detects the response signal to the CNG signal and automatically shifts to the facsimile operation to perform the facsimile communication.

The terminal PO1 of the control means 11 is an output terminal for controlling the interface circuit 2, PO2 is an output terminal for controlling the CNG signal sending means 3, and PI1 is for notifying whether the response signal detecting means 4 has detected a response signal. An input terminal for receiving the number, an output terminal for instructing the dial means 6 to dial the called terminal number, a PI2 input terminal for the speakerphone means 5, and an output terminal PO4 for controlling the mute means 8. , PI3 is an input terminal for informing the presence / absence of a document from the transmission document detecting means 9, PO
Reference numeral 5 is an output terminal for controlling the FAX unit 10.

FIG. 2 is a flow chart showing the operation of this apparatus. The operation of the facsimile apparatus configured as described above will be described below.

When the operator of the calling terminal operates the speakerphone means 5 (S1), the control means 11 causes the interface circuit 2 to capture the telephone line 1 at the output terminal P.
Instruct from O1 (S2). After the line is closed, the control means 11 instructs the dial means 6 from the output terminal PO3 to dial the called terminal number input by the operator (S).
3).

Further, the control means 11 instructs the mute means 8 from the output terminal PO4 to mute the microphone 7 (S4). The dial means 6 sends a dial signal to the telephone line 1 according to the operator's input (S5). Then, after the dialing is completed, the control means 11 causes the transmission document detecting means 9
Further, it is taken from the input terminal PI3 whether or not the transmission original is set in the apparatus (S6). If the transmission original is not set in the apparatus, the mute means 8 is instructed to release the mute of the microphone 7 from the output terminal PO4.
(S11) After the operator of the called terminal responds in the same manner as the normal telephone operation, the telephone call operation is performed (S12).

Next, when the transmission original is set in the apparatus, the control means 11 instructs the CNG signal transmission means 3 to output a CNG signal to the called terminal through the output terminal PO2 and receives it. Then, the CNG signal transmitting means 3 starts to transmit the CNG signal (S7).

After that, the response signal detecting means 4 starts a check operation as to whether or not a facsimile response signal to the CNG signal is returned from the called terminal (S8).

When the response signal to the CNG signal is returned from the called terminal and the response signal detecting means 4 informs the input terminal PI1 of the control means 11 that the response signal to the CNG signal is detected, the control means 11 outputs the signal. From terminal PO5 to F
