Abstract

PURPOSE:To enable an operator at a facsimile equipment on the transmission side to instantaneously judge the status of a facsimile equipment on the opposite side by constituting the titled system so that the reception side monitors the function of its own respective operating parts, reports the result of the monitoring, and transmits the reception-unable factor included in the monitoring result through a line at a time when a call comes in. CONSTITUTION:If there is an incoming call, the reception side checks the presence/absence of information regarding the reception unable factor of an operating part supplied from a communication control part 10; if this information is not registered, a normal reception is executed. On the other hand, if this unable function factor information is registered, an NSF (non standard frame) signal including an unable factor information is transmitted. Thereafter, the reception side monitors the reception of a DCN(disconnection) signal from the transmission side, and at the time of receiving it, the line is released. As a result, the operator at the facsimile equipment on the transmission side can immediately judge the status of the facsimile equipment on the opposite side.

Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a facsimile control system, and in particular, when a facsimile device is used to send a document, the facsimile device at the other end may fail to receive the document due to a paper jam, no receiving paper, copying, etc. The present invention relates to a facsimile control system that detects the above-mentioned unreceivable state of a receiving facsimile machine at the protocol stage and notifies the transmitting side operator of the unreceivable state.

Prior Art In the conventional control system for facsimile machines,
If a situation occurs on the receiving side, such as out of paper, paper jam, copying, storage memory overflow, etc., and the receiving side is unable to receive a call, only the telephone will ring. .

However, this state is indistinguishable from the state in which the receiving facsimile machine is turned off, so the sending operator is unaware of the above trouble and ends up repeating transmissions over and over again. There was a serious problem of reduced usage efficiency.

This will be explained in detail below.

Figure 5 shows an example of a non-standard protocol for G3 facsimile, which has an automatic dialing function (AA type NCU).
This figure shows an example of a facsimile machine (installed).

In this device, if the receiving side is normal, the communication flow from turning on the facsimile start switch until the end is as shown in Figure 5. or,
When reception is not possible, such as when recording paper is jammed or copying is in progress, the receiving side does not close the line and therefore does not output an N5F (non-standard frame) signal.

Since the receiving side does not close the line, the sending side only hears the ringing tone after the dialing is sent. Conventionally, in such a case, as described above, the transmitting side once releases the line and then tries again after a certain period of time.

However, with this method, the line is tied up for a long time, resulting in a decrease in efficiency.

Purpose The present invention has been made in view of the above circumstances, and its purpose is to solve the above-mentioned problems in the conventional facsimile control system, so that the operator of the sending facsimile machine can control the status of the other facsimile machine. It is an object of the present invention to provide a facsimile control method that can immediately determine the facsimile machine and improve the usage efficiency of a facsimile machine.

Configuration The above-mentioned object of the present invention is to provide a facsimile machine having an operating unit such as a scanner or a plotter, an image information compression/expansion unit, a modem, a network control unit 2, a communication control unit, a system control unit that controls these, and an automatic transmission function. By configuring the system to monitor the functions of each of the operating units and report the monitoring results.

This is achieved by a facsimile control system characterized in that, when there is an incoming call, the monitoring result that is the cause of unreceivable reception is sent via a line.

EMBODIMENT OF THE INVENTION Hereinafter, the structure of this invention will be explained in detail based on an Example.

FIG. 3 is a block configuration diagram of a facsimile machine showing an embodiment of the present invention. In FIG. 4 is a modem; 5 is a network control unit (NCU) that controls a line 6; Further, 7 is a plotter section for writing image information on recording paper, 8 is a recording circuit section for converting the image information signal into a signal according to the plotter section 7, 9 is a system control section for managing and controlling the entire apparatus, and 10 is a system control section for managing and controlling the entire apparatus. A communication control section 11 indicates an operation section such as a numeric keypad for controlling facsimile communication.

The system control section monitors each operating section via a sensing means (not shown), for example, the presence or absence of recording paper in the plotter section 7 and the occurrence of a jam.

It monitors whether the copy function is used or not, and has the function of reporting the monitoring results to the communication control unit 10.
The communication control unit 10 has a function of registering this report result.

FIG. 1 is a processing flowchart of the communication control section 10. As shown in FIG. The main points of this process are as follows.

The incoming call is monitored (step 21), and if there is an incoming call, the line is closed (step 22).
Step 23), the system controller 10 checks whether there is information about troubles in the operating section (operating section trouble information) from the system control section 10 (step 24), and the operating section trouble information is registered. If not,
Proceeding to step 28, a normal reception flow (see FIG. 5) is performed.

Further, in the check at step 24, if operating section trouble information is registered, the process proceeds to step 25, where an NSF signal containing trouble information as described later is sent. After that, DCN (call release signal) from the sending side
The reception is monitored (Step 26), and when the reception is received, the 9th line is released (Step 27).

The above procedure is summarized in Figure 2.

Further, FIGS. 4(A) and 4(B) show details of the NSF signal including the above-mentioned trouble information. Figure 4 (A) shows its overall configuration, and Figure 4 (B) shows more details of the PIF. In both figures, F is a flag, and A
F indicates an address field, CF a control field, FCF a facsimile control field, and PIF a facsimile information field. Further, FCS is a facsimile check field.

Facsimile information field P above
IF is CCITT member code 31° and industry association code 32. NSF identification code 33 and facsimile information 3
4, and in this facsimile information 34g,
The above-mentioned operating unit trouble information is set.

The other party's (sending source) facsimile machine that has received the operating unit trouble information as described above notifies the operator of the facsimile machine of this information through a display, voice, reception result report, or the like. The operator can analyze this information and take the following countermeasures depending on its contents.

For example, if the plotter section runs out of recording paper or a jam occurs, the operator of the facsimile machine that sent the information can be contacted and the operator of the facsimile machine that sent the information can be contacted and the other party's facsimile machine has copy function. If it is in use, you can resend it after a while.

effect As described above, according to the present invention, there is provided a scanner.

Monitors the functions of the operating units such as a plotter, the image information compression/expansion unit, the modem, the network control unit 2 communication control unit, the system control unit that controls these, and the facsimile machine that has an automatic dialing function. By configuring the system to report the monitoring results, when there is an incoming call,
Since the monitoring results that are the cause of unreceivable reception are sent through a single line, the operator of the sending facsimile machine can immediately determine the status of the facsimile machine at the other end. This has the remarkable effect of realizing a facsimile control system that can improve usage efficiency.
