Abstract

PURPOSE:To give priority to regular reception and recording by means of a recording paper by delaying the transmission timing of a response message as against an incoming call from a terminal while a paper lacks by means of prescribed time. CONSTITUTION:A paper lacking detection means 4 detecting that the reception recording paper comes to a paper lacking state, an incoming call detection means 3 detecting the incoming call from the line of an integrated digital service network (ISDN) 1 and a control means 7 delaying the transmission timing of the response message as against the incoming call by prescribed time when the incoming call is detected in the paper lacking state are provided. Consequently, a terminal where the paper is not rumming out is given the priority of the response to the incoming call compared to the terminal where the paper lacks. Thus, the generation frequency of memory substitution reception as against the incoming call from ISDN is considerably reduced and an original by the terminal where the paper is not lacked is preferentially received.

Description

Detailed Description of the Invention (Objective of the Invention) (Industrial Application Field) The present invention relates to a facsimile device that is operated by connecting to an integrated digital service network (hereinafter referred to as 15DN).
In particular, the present invention relates to improvements in a call response device provided within the facsimile machine.

(Prior Art) As is well known, in a public telephone network or a DDX network, only one facsimile machine is connected to one line, so the control of answering incoming calls can be handled as a problem for that facsimile machine alone.

For example, if a call arrives at a facsimile VC machine that is out of paper in the public telephone network or DDX network, there will be no operational problem even if the facsimile machine responds to the call through memory proxy reception or the like.

By the way, more and more facsimile machines compatible with I5DN, which have become popular in recent years, have the above-mentioned memory proxy reception function.

As is well known, L5DN allows up to eight terminals to be connected via bus to one line, and when a call is received while connected to the bus, the network will select the first one from among the multiple terminals that answered the call. The responses are accepted in order, and control is performed such that only one terminal is allowed to communicate.

The state of this control will be briefly explained with reference to the general communication procedure in this type of l5DN compatible facsimile machine shown in FIG.

In FIG. 3, a response message is sent to the exchange from the facsimile machine @(X) that first responded to the incoming call from the 15DN (for convenience, an example of responding via the user is shown). ), then exchange! After waiting for a response confirmation message to be sent back from km (see B in the diagram), the communication status changes.

At this time, the exchange sends a release message to the facsimile g@(Y> that has responded R) (C in the diagram), and the facsimile machine @(Y) that receives this sends a release completion message back to the exchange. After doing so (D in the figure), the device enters the state of waiting for the next call.

Here, it is assumed that the facsimile machine (X) has received recording paper remaining, and the facsimile machine (Y) is out of paper.

If the facsimile machine (X) answers 125 first in response to an incoming call in such a state, as shown in FIG. 3, the normal recording operation using the receiving recording paper will be performed, and there will be no problem.

However, if facsimile 8@(Y) responds to the incoming call first, even though there is another terminal called facsimile machine (X) that can record normal reception, if facsimile machine (Y) receives the memory proxy reception. was to be held.

(Problem to be Solved by the Invention) As described above, with the above-mentioned conventional l5DN compatible facsimile machines, as long as they have a memory proxy reception function, they can respond to incoming calls on a first-come, first-served basis regardless of whether there is a paper shortage or not. Despite the existence of terminals that can receive data using recording paper, there is a problem in that the chances of memory proxy reception are increasing, which is undesirable from an operational point of view.

The present invention has been made in view of the above circumstances, and
It is an object of the present invention to provide a facsimile device which can reduce the frequency of occurrence of memory proxy reception for incoming calls from N as much as possible, and can preferentially receive documents by terminals that are not out of paper.

[Structure of the invention]

(Means for Solving the Problems) The facsimile apparatus of the present invention includes a paper-out detection means for detecting when a received record paper is out of paper, and a paper-out detection means for detecting an incoming call from a line of an integrated digital service network. and a control means for delaying the sending timing of a response message to the incoming call by a predetermined time when an incoming call is detected in a paper out state.

(Function) In the facsimile apparatus of the present invention, for a terminal out of paper among the plurality of terminals connected to the l5DN via the bus,
When waiting for an incoming call, the timing of sending a response message to the caller is controlled to be delayed by a predetermined time compared to other terminals that are not out of paper.

As a result, terminals that are not out of paper have a higher priority for answering incoming calls than terminals that are out of paper, and as a result, terminals that are out of paper respond to incoming calls before other normal terminals. The frequency at which memory proxy reception is performed can be significantly reduced.

(Example) Hereinafter, an example of the present invention will be described in detail based on the accompanying drawings.

FIG. 1 is a ten diagram showing one embodiment of a facsimile apparatus according to the present invention, in which 1 is an l5DN to which this facsimile apparatus is connected to a bus together with other terminals, and 2 is an l5DN1.
3 is the network distribution department that controls the interface between

Next, an example of the receiving operation in this facsimile machine will be described in detail with reference to the flowchart of FIG.

In the facsimile machine shown in FIG. 1, when there is an incoming call from the 15DN1, this fact is detected by the incoming call detection unit 3 through the network control unit 2.

The main 1hlJ device unit 7 monitors the detection output of the incoming call detection unit 3 and determines whether there is an incoming call (step 20
1).

Here, if it is determined that there is an incoming call, then the main control section 7 refers to the detection result of the paper shortage detection section 4 and determines whether or not the own terminal is out of paper (step 202).

If there is no paper shortage, the facsimile communication controller 5 is immediately instructed to send a response message back to the sender (step 203).

Thereafter, this receiving terminal waits for the reception of a response IN acknowledgment message from the exchange in response to the response message, and shifts to a communicating state.

During this time, the main control unit 7 monitors whether the communication has ended or not (step 204), and at the same time as the communication ends, performs a line disconnection process based on a disconnection command signal sent from the calling side, and ends the operation (step 204). 205).

On the other hand, if it is determined in step 202 that there is a paper shortage, then the main control section 7 sends a paging message to the exchange (step 206).

Thereafter, the main control unit 7 determines whether a predetermined time period set in advance has elapsed (step 207).

If it is determined that the predetermined time has not elapsed, then the main control section 7 checks whether there is a disconnection instruction from the exchange (step 208).

Specifically, in step 208, a signal corresponding to the release message (C in the figure) sent from the exchange to the destination terminal (Y) in the communication procedure shown in FIG. 3 is checked.

As described above, this release message means that among the terminals connected to each other via the bus, a terminal other than the own terminal has already responded to the incoming call at that time.

Therefore, when the main control unit 7 recognizes that a disconnection instruction has been received within the predetermined time, it immediately performs the disconnection process (step 205) and ends the operation.

In contrast, step 207 is performed without the above-mentioned cutting instruction.
If it is determined that the predetermined time has elapsed, the facsimile communication control unit 5 immediately sends a response message to the exchange (step 203).

Thereafter, the receiving terminal waits for a response confirmation message from the exchange and shifts to a communicating state, but since it is out of paper at this time, it will respond to the communication using its memory reception function. .

During this time, the main control unit 7 monitors whether the communication has ended or not (step 204), and disconnects the line by a disconnection command signal sent from the calling side at the same time as the communication ends.
The operation ends (step 205).

In the above control, the process of step 207 is performed to give priority to the incoming call response to a normal terminal that is not out of paper when the receiving terminal is out of paper.

In other words, the present invention increases the priority of the terminal's incoming call response when it is out of paper by delaying the sending timing of a response message to the caller by a predetermined period of time ( ) for a terminal that is out of paper.

As a concrete delay time, a time of at least 1 second or more is required.

In this way, by making the sending of a response message from a terminal that is out of paper more efficient, the chances of incoming calls to other normal terminals during that time increase, and unnecessary activation of the memory proxy reception function can be avoided.

(Effects of the Invention) As explained above, according to the facsimile apparatus of the present invention, when a call is received from an 15DN that accommodates a plurality of terminals via bus connection, the timing of sending a response message to the above call from a terminal that is out of paper. Since the reception is delayed by a predetermined period of time, the memory proxy reception function does not work unnecessarily, and there is an excellent advantage that efficient operation can be realized, giving priority to normal reception recording using recording paper.
