Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a facsimile communication system that notifies a transmitting device of the type of abnormality that occurs in a receiving device while receiving an image signal.

[Technical background of the invention]

In general, facsimile machines have a system that, when an error occurs in the receiving device while recording image information, displays the type of error, such as a paper jam, and notifies the operator of the receiving device of what kind of error has occurred. ing.

Furthermore, on the transmitting device side, abnormalities such as training errors are detected before the image signal is transmitted, and the operator is notified. However, if an abnormality occurs in the receiving device while transmitting an image signal, an end-of-message signal (EOM) is sent from the transmitting device to the receiving device when the image signal has been transmitted to the receiving device. Multiple signal (MP
S), it was only known that some abnormality had occurred in the receiving device when there was no clear response to a signal indicating that the image signal had been transmitted, such as an end-of-procedure signal (EOP). If an abnormality occurs in the receiving device as described above, the operator on the transmitting device side has to perform an operation to send the image information to the receiving device again.

[Problems with background technology]

However, the time required to remove the abnormality varies depending on the type of abnormality that occurs in the receiving device. For example, in the case of a paper jam that can be removed relatively quickly, such as a paper jam, the receiving device can return to a normal state by the time the transmitting device operator performs the next operation to send image information. The sex is great. However, if it takes a relatively long time, such as when the recording paper has run out and must be loaded, the operator of the transmitting device may try to send the image information again before the problem on the receiving device side is resolved. It's very possible.

Generally, the receiving device is configured not to accept image information from the transmitting device until the abnormality is removed.
In such a case, the transmitting device had to send the image information again.

Recently, there are also receiving devices that store received image signals in a memory instead of outputting them to recording paper as image information. If a memory error occurs while receiving image signals in such a receiving device, it may take several days to complete the process. will also attempt to send. Then, in the end, the operator on the transmitting device side must contact the receiving device side by telephone or the like to confirm.

As described above, there is a problem in that the transmitting device is not notified of the nature of the abnormality that occurs in the receiving device while receiving image signals, which imposes a large burden on the operator of the transmitting device. Ta.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to eliminate the above-mentioned drawbacks and provide a facsimile communication system that does not place a burden on the operator of the transmitting device even if an abnormality occurs in the receiving device during image signal reception.

[Summary of the invention]

The present invention achieves the above object by notifying the transmitting device of the type of abnormality when an abnormality occurs in the receiving device during image signal reception.

[Embodiments of the invention]

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

FIG. 1 is a block diagram for explaining one embodiment of the present invention. 1 is a transmitting device that converts image information into an image signal and transmits the image signal; 2 is a receiving device that records the image signal transmitted from the transmitting device 1 as image information. 3 is a reading unit that reads image information, and 4 is a receiving device 2 that uses the read image information as an image signal.
5 and 6 are modems, 7 is a transmitting device 1
8 is a recording unit that records the received image signal as image information; 9i to 9n indicate the type of abnormality that has occurred in the receiving device 2, such as a recording paper jam or a recording paper shortage. 10 is a transmitting unit that is a transmitting unit that transmits the type of abnormality to the transmitting device 1; 11 is a receiving device that receives the type of abnormality transmitted from the receiving device 2; 12 is a display unit that displays the type of abnormality, 13 is a control unit that controls the transmitting device 1, and 14
is a control unit that controls the receiving device 2.

The image information read by the reading section 3 is transmitted as an image signal from the transmitting section 4 to the receiving device 2 via the modem 5, and in the receiving device 2, it is received by the receiving section 7 via the modem 6. The image signal is then recorded as image information in the recording section 8.

Now, if an abnormality occurs in the receiving device 2 while receiving an image signal, the type of abnormality in the receiving device 2 is detected by one of the abnormality detecting sections 9i to 9n.

Here, it is assumed that the abnormality that has occurred is a recording paper jam, and that the recording paper jam is detected by the abnormality detection section 9i.

The controller 14 is informed that a recording paper jam has occurred during reception of the image signal. For example, during normal operation, it sends out a "L" level signal, but when a paper jam occurs, it sends out a "L" level signal.
A signal of "H" level is sent out.

When the control unit 14 of the receiving device 2 receives a call from the transmitting device 1 as shown in the flowchart of FIG. 2, the control unit 14 inputs the Nth bit (N is an arbitrary positive integer) and a non-standard device signal (hereinafter N
(referred to as SF) 17 from the transmitter 10 to the transmitter 1 to indicate that the type of abnormality can be transmitted (step 31). Next, as shown in FIG. 4, a non-standard device setting signal (hereinafter referred to as NSS) 1 is sent from the transmitting device 1.
It is checked whether the M-th bit (M is any positive integer) of the FIF 19 of No. 8 contains the special code 20 "Ijo" (step 32). If it is, the transmitting device 1 regards the type of abnormality as one that can be output, and checks whether an "H" level signal is input from the abnormality detection means 9i while receiving the image signal ( Step 33), if it is present, it is assumed that a recording paper jam has occurred, and instead of a message confirmation signal (hereinafter referred to as MCF), the X bit of the FIF 22 shown in FIG. ) is an error notification signal 2 with error code 23 “Kamitsumari”
1 from the transmitter 10 to the transmitter 1 (step 3
4).

In addition, the code 2 is in the M bit of FIF19 of SS18.
0 "IJO" is not input, or when the "H" level signal is not input from the IJO detection means 91, the abnormality notification signal 21 is not output (step 3).
5).

On the other hand, as shown in FIG. 6, the control unit 13 of the transmitting device 1 checks whether the special code 16 "Ijo" is included in the N bit of the FIF 15 of the NSF 17 sent from the receiving device 2 (step 41). . If it is, it is receiver 2.
considers that the type of abnormality that occurred during reception of the image signal can be transmitted, and puts code 20 "Ijo" in the Mth bit of FIF 19 of NSS 18 to indicate that it is possible to receive the abnormality detection signal 21 ( Step 42).

Then, it transmits the image signal and checks whether or not the abnormality notification signal 21 is received from the receiving device 2 instead of the MCF (step 43). When the abnormality notification signal 21 is received, the FIF 22 of the abnormality notification signal 21 The bit-th error code 23 is output to the display unit 12 (step 44). Here, M
If the CF has been received, it is checked whether all image information has been transmitted (step 46), and if not, the process returns to step 43.

Note that the NSF received from the receiving device 2 in step 41
If the code 16 "IJOU" is not included in the N-th bit of the FIF 15, the receiving device 2 considers that the abnormality notification signal 21 cannot be sent, and does not detect the abnormality notification signal 21 (step 47).

Further, the display unit 12 displays the type of abnormality in correspondence with the error code 23. Here, since the type of abnormality is assumed to be a paper jam in the recording paper, the display is, for example, "kilokushizumari".

As described above, in the Japanese embodiment, the type of abnormality that occurs in the receiving device 2 during image signal reception can be transmitted to the transmitting device 1 side, so that the burden on the operator of the transmitting device 1 side can be reduced.

Furthermore, in this embodiment, the type of abnormality is displayed on the display unit 12, which has the effect of making it particularly easy for the operator of the transmitting device 1 to confirm.

In this embodiment, the display unit 12 is provided as an output means for outputting the type of abnormality, but the display unit 12 is not limited to this example as long as the type of abnormality can be notified to the transmitting device 1 side. A plurality of lamps may be provided and the lamp corresponding to the abnormality may be turned on.

In addition, although this embodiment describes the case where one type of abnormality occurs, a memory is provided that stores the time required for recovery depending on the type of abnormality. Alternatively, the error code 23 that requires the longest time for recovery may be included in the abnormality notification signal 21.

〔Effect of the invention〕

As described in detail above, in the present invention, if an abnormality occurs in the receiving device while receiving an image signal, the type of the abnormality is notified to the transmitting device. Therefore, even if an abnormality occurs in the receiving device during reception of image signals, a facsimile communication system can be obtained that does not place a burden on the operator at the transmitting site.
