Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a telephone calling system in facsimile.

5-Generally, when communicating by facsimile, it is often necessary not only to simply exchange facsimile data, but also to communicate various matters by telephone with the other party.

For this reason, in facsimile, telephone contact is performed by automatically sending a "calling code" from the conversation requesting side before and after exchanging facsimile data.

By the way, the method that has been proposed in the past for making it possible to actually talk on the phone after sending out this call code is to simply send a call code from the side requesting the conversation and then call the operator on both devices. All it did was generate an audible sound to let you know.

For this reason, especially when the operator on the called side picks up the receiver, the person on the other end cannot determine whether the facsimile machine has switched to the telephone or not, and the operator must wait on the phone for a while, feeling irritated. There were some unavoidable flaws.

The present invention eliminates the drawbacks of the prior art described above, and provides an advantageous method in which, when either the calling party or the called party picks up the telephone receiver, it is possible to tell whether or not the other party's operator has answered the telephone and switched from the facsimile machine to the telephone. The purpose is to ensure that In order to achieve this object, the present invention causes both devices to generate an audible tone when a calling code is sent out, and at the same time sends an audible tone to the line. stop listening,
It is characterized by being able to switch to a telephone.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a facsimile system configuration diagram showing an embodiment of the present invention. Blocks A and B indicate two facsimile machines with which communication is carried out, furthermore, IA and IB are audible tone stop pushbuttons, and 2A and 2B are audible tone stop pushbuttons. Speakers, 3A, 3B are system controllers, 4A, 4B are modems, 5A, 5B are telephones,
6A and 6B are switching relay contacts. The caller of the person who wants to make a phone call sets a call code in a predetermined control field in the control procedure that is performed before and after message communication, depending on when the caller wants to make the call. Send it to the side.

For example, when proc A is the sending side and proc B is the receiving side, as shown in Figure 2, if you want to call the operator of the B side after sending facsimile data C from the A side to the B side and make a telephone contact, Post-message command (EOP, MPS) on the A side
, EOP, etc.), the call code D is set in the control field and sent.

On the A side, after the system controller 3A sends the call code D, it drives the speaker 2A once and simultaneously sends an audible sound E to the line in order to inform the operator that the call has started.

As this audible sound E, for example, facsimile equipment is generally equipped with a 2100H noise generation circuit to send out a called station identification signal (CEDk) when switching from the telephone to the equipment side at the beginning of communication. The intermittent sound may be sent out via the model 4A using the above method.

When the B side receives the call code D, the system controller 3B decodes it and drives the speaker 2B by 1 in the same way as the A side, and at the same time sends the audible sound F to the line.

In this way, when the call code D is sent out, the speakers on both the A side and the B side are activated to notify the operator that there is a telephone call.

When the operator noticed this ringing sound, he pressed button 1A.
, 1B, the system controllers 3A, 3B will
The driving of the speakers 2A and 2B and the transmission of the audible sounds E and F to the line are stopped.

At the same time, switching signals G and H are output to switch the relay contacts 6A and 6B to the dotted line positions. As a result, the second
As shown in the figure, for example, if the A-side operator notices the ringing tone first and presses the push button 1A, the driving of the speaker 2A and the transmission of the audible sound E are stopped, and the line is connected to the telephone 5A.

When the operator picks up the handset of telephone 5A, audible tone F is heard. This shows that the operator on the B side is not yet on the line. Next, when the B-side operator notices the ringing tone and presses the push button 1B, the driving of the speaker 2B and the transmission of the audible sound F are stopped, and the line is switched to the telephone 5B. When the operator on the B side picks up the telephone, he does not hear any sound, so he knows that the operator on the A side is on the line. In addition, if the pushbuttons 1A and 1B are not pressed, the driving of the speakers 2A and 2B and the transmission of the audible sounds E and F will be stopped after a specified time has elapsed, and at the same time the line will be switched to the telephone 5.
It can be switched to A and 5B.

As a result, it is known that a call can be made while the speaker is operating, and the person who picks up the phone first also hears the audible tone, so there is no need to wait forever for the other party to answer the phone.

By the way, in the above embodiment, the push buttons 1A and 1B are pressed to notify the other party that you have answered the telephone, but this can be done by omitting the push buttons 1A and 1B and picking up the receiver. It can also be configured to automatically detect and notify the other party.

That is, FIG. 3 shows a configuration diagram of a B-side facsimile device for this purpose. In the figure, the same symbols as in FIG. 1 indicate the same or corresponding parts, and furthermore, 6C to 6E are switched by the switching signal H. 7 is a power supply, 8 is a photocoupler, and 9 is an amplifier.

By configuring the B-side facsimile device in this way, when the speaker 2B is activated and the handset of the telephone 5B is picked up, the operation circuit of the photocoupler 8 is formed, and the detection signal thereof is extracted from the amplifier 9. Can be done.

Therefore, if this signal is used in place of the output of the push button 1B in FIG. 1, the driving of the speaker 2B and the transmission of the town hearing sound F will be stopped, and the switching signal H will be output, and the line will be switched to the telephone 5B. , and the desired telephone call operation can be performed.

It goes without saying that the sound source for operating the speakers may be the same as the sound source for sending out to the line, or may be different. As described above, according to the present invention, after a call code is sent, both devices generate an audible sound and simultaneously send it to the line, while the operator who listens to the audible sound stops the audible sound. Since the switch is switched to a telephone, even if the operator is away from the equipment while data is being sent and received, an audible tone will be emitted when a telephone call is required, and the operator will be able to tell when a telephone call is required. As a result of being able to judge whether or not the other party has answered the telephone based on the presence or absence of an audible sound when the operator picks up the telephone receiver, there is no need to wait at the telephone end without knowing whether or not the other party is answering the telephone.

Claims (1)

[Claims] 1. During facsimile communication, the facsimile machine on the side that receives a telephone contact instruction from the operator sends a call code to the other party, then generates an audible tone and sends it to the line, while the facsimile machine on the other side that receives it sends a call code to the other party. generates an audible tone and sends it to the line, and furthermore, in response to the generation of the audible tone, the facsimile machine on the side where the operator has performed the operation stops generating and transmitting the audible tone, and connects the line to the telephone side.
