Abstract

PURPOSE:To improve the call processing of an operator by confirming a caller telephone number when a call comes from other line during the execution of communication, requesting the communication standby to the caller and executing the communication in standby after the end of communication. CONSTITUTION:A picture signal inputted from a line I or II is tentatively stored in a RAM 13 via a MODEM or an NCU 21 or 22 and a picture signal read from the RAM 13 is fed to a recording section 18 via an interface 17. When the facsimile equipment of the destination uses the line I and facsimile communication is implemented and a call comes from the other line II, the caller telephone number is confirmed, the communication standby is requested to the caller and the standby communication is executed after the end of communication. Since the picture information of the original of the caller is subjected to immediate polling reception, the call processing by the operator of the caller is not entirely required.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a facsimile machine that accommodates multiple lines.

[Background of the Invention] A facsimile machine may accommodate a single line or accommodate multiple lines.

The former is commonly used, but since a facsimile machine that can accommodate multiple lines has a wider range of uses, it is a form that can be used frequently when it has a central function rather than being used as a terminal. .

[Problems to be Solved by the Invention] By the way, in a facsimile machine that accommodates a plurality of lines, when a certain line is used for communication, if there is an incoming call ε from another line, Usually the call is ignored. Therefore, the sender receives a signal indicating that the facsimile machine is in use (for example, a busy-1
No. 8).

Therefore, it is extremely inconvenient for the originating operator because he or she cannot know when the facsimile machine will be available and ready for communication. Furthermore, it often happens that a line is connected for the first time after several transmission processes.

Even though a plurality of lines are accommodated in this way, it takes time and effort to make a call, and also leads to wasted time for making a call.

Therefore, the present invention solves these problems and proposes a facsimile machine with improved call processing.

"Means for Solving the Problems" In order to solve the above-mentioned problems, the present invention provides a facsimile machine that accommodates a plurality of lines, so that when i communications are being carried out, an incoming call from another line is received. When a caller's telephone number is received, the sender must have a means of confirming the telephone number of the caller, and a means of requesting the sender to wait for communication, and then waiting and executing the communication after one communication is completed. It is.

[Operation] In a facsimile machine that accommodates multiple lines, the following communication procedure is performed.

First, when a call is received from another line while one communication is in progress, check the phone number of the caller,
Memorize. After that, the sender is requested to wait for communication. Then, after one communication is completed, a transition is made to the polling receiver 5 where the waiting communication is executed.

Then, when a call is received from another line and the facsimile machine is in use, that line will be temporarily disconnected, but as soon as the facsimile machine finishes the current communication process, the call will be sent to the caller. Dial is automatically performed, and if the line is free, it will be a polling reception (M).

Therefore, since the image information of the originating original can be immediately polled and received, the calling process performed by the originating operator is completely eliminated.

Since the sender is requested to stand by for communication, there is no risk that the operator will remove the original.

[Embodiment 1] Next, an example of a facsimile apparatus according to the present invention will be described in detail with reference to FIG. 1 and subsequent figures.

FIG. 1 shows an example of communication control means 10 in a facsimile machine, and it is assumed that there are a plurality of communication lines d accommodated. This example shows a case where two communication lines 1 and II are accommodated.

In the figure, 11 is a CPU that manages control. 12 is a ROM 11 in which various @control programs are stored.
Reference numeral 3 denotes a RAM for storing the incoming 3-picture signal and the pictures to be transmitted (number 8, etc.).

The image signal read by the image reading unit 14 is stored in the RAM 13 or directly transmitted to the interface 15.
Modem and line j1111 circuit (NCU) 2 through
1 or 22. Also, line ■ or 1
The image input from 1 (No. 8 is the image input from these modems and NCU2
1 or 2, and is temporarily stored in the RAM 13. The image signal read out from the RAM 13 is then supplied to the recording section 18 via the interface 17 and recorded.

It is also possible to record the i-signal directly without storing it in the RAM 13.

The telephone number of the destination party is supplied to the display section 20 via the interface 19 and displayed thereon.

In this invention, when a call is received from another line while one communication is in progress, the telephone number of the caller is confirmed, and the third caller is requested to wait for communication.
A series of communication procedures is executed in which a waiting communication is executed after one communication is completed.

Therefore, the facsimile apparatus of the present invention has means for confirming the telephone number of the caller when one communication is in progress and when there is a second call from another line, and a means for confirming the caller's telephone number and instructing the caller to wait for communication. and means for executing the standby communication 3 after the completion of the i communications. However, all of these means are processed by software.

Currently, terminals that are capable of such communication processing are limited to terminals that are connected to the same 41i1 and that are equipped with a non-standard 1 function. Therefore, in phase B mode,
Non-standard function identification signal sent from called @ (destination)
A signal prompting standby processing for polling reception is inserted into the NSF signal).

To do this, first, as shown in Figure 2A, a signal (such as a flag) for executing such processing is inserted using the facsimile information field (PIF) that constitutes the NSF signal. .

For this, call out! 1 (sender) uses the FIF section of the non-standard function setting signal (NSS signal) transmitted from this to insert a signal indicating polling transmission capability.

Additionally, the called side issues a polling standby request. A request signal for this purpose (hereinafter referred to as a PRQ signal) is inserted into the front part of the FIF section as shown in FIG. 2C. In response to this, on the calling side, a display for polling standby processing and polling standby processing are performed. Based on this display content, the calling party, that is, the originating operator, knows that his or her own machine has been controlled to standby mode for performing polling transmission processing.

Now, Figure 3 shows a facsimile machine that accommodates multiple lines (
An example of communication processing at the destination (destination) is shown below.

First, if the destination facsimile machine is connected to one line, for example
When facsimile communication is being carried out using
This is the procedure when a call is received from another line II. When a call is made from the calling party to the called party to connect the line, the called party issues a 2100Hz tone number 48 (CED).
At the same time, a non-standard function identification signal (NSF signal), a called terminal identification signal (C5I signal) and a digital identification signal (DIS signal) are sent to the calling party.

In response to this, the calling side sends a transmitting terminal identification signal (TSI
4M) and a non-standard function setting signal (NSS signal). When it is desired to set a non-standard mode, non-standard content is set in this NSS signal.

The called party, which is the destination of the call, detects the telephone number of the caller from the TSI signal and stores it in memory.

The source also sends a training check signal (TC
F (ff number) is sent. In normal procedure, when this TCP signal is sent, the destination sends a reception readiness confirmation signal (CF
R signal) is sent to the source and the phase B mode ends.

However, in this invention, instead of this CFR4M, the second
The PRQ shown in Figure C (No. 8 is sent to the sender, and this PRQ
When the Q signal is analyzed, a message indicating that the polling transmission standby process is in progress is displayed on the display unit 20.The operator can now automatically select the polling transmission mode 8. I found out that it was on standby.

At the same time, the originating S source transits to the polling send I8 standby mode, whereby a line disconnection signal (DCN signal) is sent to the originating station ε, and the line II is disconnected.

At the destination, the line! When it is detected that the communication using the , the destination automatically transitions to polling reception mode immediately. Then, the image information of the source (image information obtained by manipulating the original or image information of the original stored in memory) is transmitted (ε toward the destination). It is transmitted.In other words, it is polling reception.

In this way, it is possible to automate the communication processing procedure when the caller is waiting for a line to become available, which greatly simplifies the operation.

[Effects of the Invention] As explained above, in the present invention, when a call is received from another line while one communication is being performed, the telephone number of the calling party is confirmed, and The sender is requested to wait for communication, and after one communication is completed, the waiting communication 4g is executed.

According to this, the source operator can automatically send the desired document to the destination without any special processing.

Therefore, it has a feature that can greatly improve call processing for operators.
