Description

Description: FIELD OF THE INVENTION The present invention relates to facsimile machines.

2. Description of the Related Art There is a case where a communication line and a device necessary for a call (hereinafter referred to as a communication device) are connected to one communication line, and this communication line is shared by the communication line and the communication line and used for the call and the communication. .

In the conventional facsimile equipment, when a call is needed during communication or at the start of communication, a control signal for calling the operator is sent to the other facsimile equipment, and when the signal is transmitted / received, an audiovisual display is provided to inform the operator. This made it possible to switch from communication to call.

Problems to be Solved by the Invention The conventional facsimile machine described above has the following drawbacks when it is used for voice communication and facsimile communication by one telephone line.

In other words, if the fax machine is set to be able to receive automatically, when the telephone that is not connected to the fax machine is called, the fax operator sends a call signal to the other operator in order to receive automatically. I can't.

Further, if the facsimile machine is set in a state in which it cannot be automatically received, there is a drawback that an operator's intervention is required when communicating between facsimile machines, which hinders operation.

The present invention has been made in view of the above-mentioned conventional circumstances, and therefore an object of the present invention is to provide a novel facsimile machine capable of eliminating the above-mentioned drawbacks inherent in the conventional technology. is there.

Means for Solving the Problems In order to achieve the above object, the facsimile machine according to the present invention has an auditory display that operates when an automatic incoming call is received, and receives a response signal (reception command signal) from a calling terminal. Circuit,
A circuit for detecting a call request condition by the aural display, and means for performing an aural display until a facsimile signal from the calling side is received at the time of automatic incoming call.

Embodiment Next, the present invention will be described in detail with reference to the drawings for a preferred embodiment thereof.

FIG. 1 is a block diagram showing an embodiment of the present invention, and FIGS. 2 and 3 are operation time charts thereof.

In FIG. 1 to FIG. 3, when the ringing signal detection circuit 2 detects the ringing signal 8 from the exchange, the control unit 5 detects the detected state.
The control unit 5 and the switching signal is transmitted to the relay 7,
This switching signal switches the relay 7 from the contact a side to the contact b side. At this time, the control unit 5 makes an auditory display request to the auditory display unit 6, and the auditory display 11 is provided by a buzzer or the like.

Next, the facsimile device sends the identification signal 9 created by the control unit 5 to the other side, that is, the calling side terminal through the modulation / demodulation unit 4 and the exchange. When the facsimile machine is connected to the calling side, a receiving command signal 10 is sent from the calling side, and immediately the receiving side receives the receiving command signal 10 through the modulator / demodulator 4 as shown in FIG. Then, the auditory display 11 is stopped and the communication operation of the facsimile is started.

If the facsimile machine is not connected to the other party, the command signal 10 is not received. At this time, as shown in FIG.
Since the auditory display 11 is continuous, the operator can easily identify it. When the operator lifts the handset of the telephone, the hook-off detection circuit 3 operates to notify the control unit 5 that there is a call request. When the call request is received, the control unit 5 sends a switching signal to the relay 7, whereby the relay 7 can switch the contact from b to a.

Similarly, the auditory display 11 is displayed on the auditory display unit 6 from the control unit 5.
The stop signal is output to stop the auditory display such as a buzzer and the voice call becomes possible.

It is obvious that the auditory display is the same even if it is displayed intermittently.

EFFECTS OF THE INVENTION As described above, according to the present invention, the facsimile apparatus displays an aural call when an automatic incoming call is received, and the aural display is continued until a facsimile signal is received or a call request is made. As a result, even if only one line is used for the facsimile machine, the effect that it can be easily used for telephone conversation and facsimile communication can be obtained.

Claims (1)

[Claims] Claims: 1. A facsimile apparatus for providing an auditory display when an automatic call is received, wherein a switching circuit for detecting a calling signal from an exchange and switching a communication line to a call or a facsimile communication is switched to the facsimile communication side and the auditory display circuit is operated. A control circuit, a signal receiving circuit for receiving a reception command signal from the calling terminal through the switching circuit, and a hook-off detection circuit for detecting a hook-off of the telephone, and the control circuit receives the reception command signal. When the auditory display by the auditory display circuit is stopped to start the facsimile communication operation, and when the hook-off is detected without receiving the reception command signal, the switching circuit is controlled to switch the communication line to the call side and connect. Facsimile machine characterized by the above.
