Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a facsimile device having a telephone calling function.

Traditionally, images were sent using regular telephone lines,
In a facsimile device that performs reception, the following operations are performed when communicating with the operator of the other party after the end of image communication.

(1) Reserve a call after the facsimile communication (transmission/reception of images) ends, remove the handset from the device in advance, and make the call after the facsimile communication ends.

(2) Call the operator of the other party's device using a ringing tone such as a buzzer, and then switch the call switch to start the conversation.

In (1) above, it is necessary to make a reservation for a call (voice conversation) before starting facsimile communication, so if you forget the reservation and switch to facsimile communication, the operator of the other party If the handset is not removed from the device, the line will be disconnected when the facsimile communication ends. Therefore, the call must be made again, and even if the handset is removed from the device in advance, the volume of the handset is too low to call the operator (the handset must be held against the ear). ).

The above (2) improves the drawbacks of the above (1),
When the need for a call arises during facsimile communication, by pressing the call reservation switch, when one page of facsimile communication is completed, a buzzer or the like on the other party's machine will sound to prompt the operator to make a call. Then, when the operator of the other party presses the call switch in response, the line changes from "facsimile communication" to "call".
The state changes and you can start talking.
However, if the operator of the other party is not near the facsimile machine and the response is delayed, the calling party will have to wait for a long time in silence without switching to the "talk" state, and the other party will have to wait a long time in silence. I was worried because I couldn't tell if the person was calling the operator or if the device was malfunctioning and could not be reached. In some cases, I quickly suspected that the line was broken or malfunctioning, so I hung up the handset and disconnected the line.

Further, as disclosed in Japanese Patent Application Laid-open No. 54-34709, when a call reservation switch is pressed during facsimile communication, a buzzer or the like on the other party's machine sounds when one page of facsimile communication is completed to prompt the operator to make a call. When the operator of the other party presses the call switch in response, a response signal is sent to the party making the call request, and this response signal calls the operator of the party making the call request using a buzzer or the like. .

However, in this case as well, as in the case described above, while the operator is being called by a buzzer, etc., there is no sound and the state is not switched to a "talk" state, and the operator who answered first is not aware of the other party's call. There was a problem in that it was not possible to identify what state the aircraft was in.

The present invention eliminates the conventional problems as described above,
By transmitting a signal indicating that a call is being made to the other machine while the operator on the own side is calling, the above-mentioned feeling of anxiety is removed and the line is used smoothly. That is, the present invention provides a communication means for transmitting or receiving an image signal, a communication means for making a voice call, a switching means for switching between the above communication means and the above communication means, and a communication means for switching between the above communication means and the above communication means. A call request signal generating means for generating a call request signal for making a call by the communication means, means for receiving a response signal from the other party's device in response to the call request signal, means for receiving a call request signal from the other party, a response signal generating means for generating a response signal to the other party's machine in response to the call request signal; a calling means for calling an operator on the own machine side to enable a telephone call by the talking means;
A calling signal generating means for generating a signal indicating that the calling means is calling, and automatically operating the calling means in response to reception of the call request signal or the response signal; control means for outputting a calling signal to the other party's machine, and stopping the output of the calling signal to the other party's machine in response to the own operator's response to the call by the calling means; This facsimile device is characterized in that it notifies the machine that it is currently being called by the above-mentioned call signal.

According to the present invention, while the operator on the own machine is calling, a signal indicating that the call is in progress is sent to the other party's machine, so even if the operator of the other machine answers first and switches to a call, the other party's operator cannot call. It is possible to recognize that the destination is calling an operator, and thereby the line can be used smoothly.

Hereinafter, the present invention will be explained according to the embodiments shown in the drawings.

In the figure, T is a facsimile transmitter, R is a facsimile receiver, 10 is a control circuit that controls the call procedure on the transmitter side, 11a is a call switch, 1
1b is a call switch, 11c is a transmission switch, 1
2 is a document reading circuit, 13 is a modulation circuit, 14, 34
15 is a calling signal generation circuit, 15 is a response signal detection circuit,
16, 17, 18 are relays that switch lines, 1
9 and 39 are buzzers for calling; 20 and 40 are call request display units; 21 and 41 are operation instruction display units that display, for example, ``pick up the receiver and press the call switch''; and 22 and 42 are for call calls. 30 is a control circuit for controlling communication procedures on the receiver side, 31a is a call switch, 31b is a call switch, 31c is a reception switch, 32 is a recording circuit,
33 is a response signal sending circuit, 35 is a demodulation circuit, 3
6, 37, 38 are relays for switching lines; 50;
51 is an exchange. In the figure, when performing facsimile communication, image information read by the original reading circuit 12 of the transmitter T is input to the receiver R via the control circuit 10 and exchanges 50 and 51, and is further transmitted via the control circuit 30. It is recorded by the recording circuit 32. First, when the call switch 11a (switch for sending a call request signal) is closed, the control circuit 10 of the transmitter T flashes the call request display section 20, and the call switch 11a (call request switch) operates correctly. Displays that the "call" has been accepted. Then, when the document reading circuit 12 sends out image signals for one page and facsimile communication stops,
The control circuit 10 includes a modulation circuit 13, relays 16, 1
7, 18, a call request signal is sent to the receiver R via the exchanges 50, 51. Then, the control circuit 10 switches the relay 17 to the a side and waits for a response from the receiver R.

On the other hand, the call request signal sent from the transmitter T (which becomes the call information for the receiver R) is demodulated by the demodulation circuit 35 via the relays 38 and 37 of the receiver R, and is input to the control circuit 30. Control circuit 3
0 is a buzzer 39 when the call request signal is input.
is sounded and the call request display section 40 is made to flash, thereby appealing to the auditory and visual senses of the operator of the receiver R to convey the call request from the operator of the transmitter T. At the same time, the control circuit 30 lights up the operation instruction display section 41, for example, "Pick up the handset and turn on the call switch (switch 31 to switch the relay 38 from the B side to the A side.
Please press b)", and the operator of receiver R instructs the next action to be taken. Next, the control circuit 30 switches the relay 37 to the b side to send the response signal of the response signal sending circuit 33 to the transmitter T, and then switches the relay 36 to the a side to send out the call signal sent from the calling signal generating circuit 34. A signal (ringing tone) is sent to transmitter T via relays 36, 37, 38 and exchanges 50, 51. Here, the ringing signal (ringing tone) sent from the ringing signal generation circuit 34 may be an intermittent tone of a certain frequency or other signals (for example, a chime, a music box sound,
You can use a human voice to say something like, ``We are currently calling, so please wait for a while.'' on the other hand,
When the transmitter T inputs the response signal sent from the response signal sending circuit 33 of the receiver R to the control circuit 10 via the relays 18 and 17 and the response signal detection circuit 15, the control circuit 10 switches the relay 17 to the b side. , the relay 16 is switched to the a side, and the ringing tone generated by the ringing signal generation circuit 14 is transmitted to the receiver R via the relays 16, 17, 18 and the exchanges 50, 51.
At the same time, the control circuit 10 also controls the buzzer 1.
9 to sound and operate the operation instruction display section 21. This allows the operator of the transmitter T to know that the transmitter T has finished transmitting the image signals for one page and is now in the calling state, and furthermore, the operation instruction display section 21 displays the next message. can read the actions that should be taken.

At the time when the above-described procedure is completed, both the transmitter T and the receiver R have the call request display section 20,
40 flashes, the buzzers 19, 39 sound (call information), the operation instruction display parts 21, 41 light up,
Furthermore, the ringing tone (calling signal) is in a state where it is mutually transmitted to the line. In such a state (standby state for a call), the operator of either the transmitter T or the receiver R operates the telephone 22 according to the display on the operation instruction display section 21 or 41.
or 42 (communication means) handset 22a or 42
a and press the call switch 11b or 31b (a few seconds after pressing the call switch, the relay 18
(or 38, you can pick up the handset after pressing the call switch).For the sake of explanation, operator A of the transmitter T picks up the handset 22a from the telephone 22 and presses the call switch 11b. Suppose that Then, the control circuit 10 causes the buzzer 19 to
stops the sound, turns off the operation instruction display section 21,
Switch the call request display section 20 from blinking to lighting.
Then, the relay 18 is switched to the a side and the line is connected to the telephone set 22. In this state, when Operator A puts the handset to his ear, he can hear the aforementioned ring tone (ring signal) sent from receiver R to the line, so he knows that there is no equipment malfunction or incorrect operation. , and can wait for operator B of receiver R to respond without any anxiety. On the other hand, since the operator B has been called by the ringing of the buzzer 39 (calling information), if he picks up the handset 42a and presses the call switch 31b, the control circuit 3
0 stops the buzzer 39, turns off the operation instruction display section 41, and switches the call request display section 40 from blinking to lighting. Then, the relay 38 is switched to the a side and the line is connected to the telephone set 42, so that operators A and B can talk to each other. In the example described above, we considered the case where operator A answered the call first, but even if operator B of receiver R answered first, the procedure would be the same (if operator B is called I hear something),
Even people who are not accustomed to using facsimile machines can definitely operate it easily.

In the above-mentioned embodiment, the call switch 11a,
Although the telephone switch 31a and the telephone switch 11b, 31b have been described as being separate, they can also be integrated into a "telephone switch".
