Abstract

PURPOSE:To return any concrete reception disable reason to the transmission source at the time point of call incoming in the case of disabling the reception by judging whether the reception is enabled in a reception side device system or not at the time of call incoming from another equipment and returning the result to the transmission source. CONSTITUTION:A RAM 3 stores data required for controlling the facsimile equipment, and a CPU 1 controls respective parts in the equipment according to a processing program stored in a ROM 2. A communication control part 7 exchanges a facsimile control signal with the opposite side facsimile equipment and executes the sequence of facsimile communication. When a call is incoming, the reception side equipment is changed into a reception mode regardless of whether there is any reception disable reason or not and checks the state of the system in the own equipment, namely, whether the reception is enabled or not. When recording paper sheets are exhausted and a SAF memory 9 to perform reception in place of the device is full as the checked result, for example, a reception disable information return mode is set, and information showing such a state is returned to the facsimile equipment at the transmission source.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile machine, and more particularly, when the receiving facsimile machine of the transmission destination has a reason why the receiving facsimile machine cannot receive the information, the receiving facsimile machine gives the reason why the receiving facsimile machine cannot receive the reception. The present invention relates to a facsimile device that can be transmitted to a device.

[0002]

2. Description of the Related Art In a conventional facsimile communication system, after the line connection with the transmission destination is completed, the read information is sequentially transmitted, and when all the information is transmitted, the transmission is completed and the above-mentioned line connection is made. After the completion and start of information transmission, if a trouble occurred on the transmission side or the reception side, an error generation signal was output. Also, if the recipient's fax machine becomes unreceivable due to recording paper exhaustion or the storage memory capacity being exceeded, etc. I was trying to make the connection impossible. Regarding this, for example, as disclosed in Japanese Patent Laid-Open No. 62-216577, when the self-device is abnormal, the status information of the self-device is automatically notified to a pre-registered partner. It has also been proposed to configure it.

[0003]

However, the notification of the status information of the own device in the above-mentioned prior art is limited to the destinations registered in advance, and the notification from the unspecified large number of transmission destinations is required. This is not enough for general facsimile machines that need to be considered. That is, when the above-mentioned reason why the reception is impossible is present at the time when the facsimile apparatus receives an incoming call, at that time, the specific reason for the reception failure is returned to the facsimile apparatus on the transmitting side, and the appropriate action is taken. It also means that the reason why the reception is not possible can be eliminated early. The present invention has been made in view of the above circumstances, and an object of the present invention is to solve the above-described problems in the related art and to provide a reason why reception is impossible at the time when an incoming call is received by the receiving facsimile device. In this case, it is to provide a facsimile device that can return a specific reason why reception is impossible to the facsimile device on the transmission side at that time.

[0004]

SUMMARY OF THE INVENTION The above object of the present invention is to provide a facsimile apparatus having a line control circuit for controlling the exchange of information with a communication line, and providing means for judging whether or not reception is possible within the facsimile apparatus system. When there is an incoming call from another facsimile machine via the communication line, the line control circuit shifts to the reception mode, the judging means checks the state of the system in the facsimile machine, and if the reception is impossible, Is achieved by a facsimile device characterized in that information indicating that is returned to the facsimile device of the transmission source.

[0005]

In the facsimile apparatus according to the present invention, when there is an unreceivable reason at the time when an incoming call arrives at the facsimile apparatus, a specific unacceptable reason is returned to the sending facsimile apparatus at that time. By doing so, appropriate measures can be taken on the transmitting side, which leads to early elimination of the reason why reception is impossible. In addition, the sending facsimile machine has a function to stop the recalling operation when it receives the reason why it cannot be received from the destination facsimile machine. Is possible.

The operation of the present embodiment configured as described above will be described below with reference to the flow chart shown in FIG. On the transmitting side, first, the document is set (step 21), the destination telephone number is input (step 22), and the start button is pressed (step 23), as in the normal procedure. Based on this, a call is made to the corresponding number (step 24) and an incoming call is made to the receiving side facsimile device (step 41). In the receiving side device, when there is an incoming call (step 41), regardless of whether or not there is a reason why reception is not possible, the process moves to the receiving mode (step 42). It is checked whether it is possible (step 43). If the result of this check is that reception is possible (step 44), the routine moves to the normal reception processing of step 45. Since this case is outside the scope of the present invention, detailed description will be omitted. On the other hand, as a result of the above check, if reception is not possible (step 4

First, the NSC transmission request information is placed on the NSF and transmitted (step 46).

The transmitting side device analyzes the above NSF information (step 25) and checks whether or not there is an NSC transmission request.
(Step 26). If the result of this check is that there is no NSC transmission request, the routine proceeds to the normal processing of step 27. Further, as a result of the above check, if there is an NSC transmission request, NSC is transmitted. The receiving side apparatus shifts to the polling transmission operation because it has received the NSC (step 47). The information to be sent is: * A description of the situation such as "Currently, we are in a situation where we cannot receive the message." * Explanation of "Reason why we are unable to receive the message." Step 50). The device on the transmission side that receives this prints out the above information. FIG. 3 shows an example of the format of the reception failure reason report. In addition, here
Detailed description of the procedure for polling transmission itself is omitted. According to the above-described embodiment, the operator of the transmission side device, who sees the printed information, can understand the cause of the unreceivability from the received information and can promptly take necessary measures.

Next, another embodiment of the present invention will be described. The first-described embodiment corresponds to claim 4. FIG. 4 shows the main part of the transmission control flow according to this embodiment. Here, a normal NSF (C) as shown in FIG.
Instead of "RTI", information about the reason why reception is not possible is added and transmitted. An example is shown in FIG. After that NS
