Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a facsimile machine, and more particularly to a facsimile machine having an interrupt function.

[Conventional technology and its problems]

Conventionally, when trying to use a first facsimile to transmit data from a first facsimile to a third facsimile, the first facsimile is transmitting a large number of original documents, such as several dozen, to the second facsimile. If a transmission was in progress, the user did not have to wait a long time for the transmission to the second facsimile to finish. Furthermore, if the document to be sent to the third facsimile is urgent and important, such a long transmission delay may lead to a large loss in the contents of the document. Emphasis was placed on urgent and important manuscripts, and the transmission of manuscripts from the first 7-axis facsimile to the second facsimile was interrupted, and even if a heavily loaded manuscript was sent to the third 7-axis, the transmission was interrupted. In order to restore the transmission of originals to the second 7 occi, it is necessary to follow the procedure from the beginning and call again. You can call again and be connected immediately, but if the other party is already accepting another transmission or is transmitting to another device, you will have to wait.

This time, on the other hand, the person who was sending the fax to the second fax machine had to wait, which often resulted in wasted time.

[Means for solving problems]

The uninvented facsimile machine compensates for the above-mentioned drawbacks by providing an inventive facsimile machine which, while transmitting a document from the first facsimile machine to the second facsimile machine,
In order to smoothly transmit data to the facsimile machine, the first facsimile machine has a function to send an interrupt signal to the second facsimile machine, and a function to automatically transmit the interrupt signal to the second facsimile machine after the transmission to the third facsimile machine is completed. The second facsimile machine also has a function to send a signal to the first facsimile machine to indicate that the interrupt signal has been accepted. The first facsimile machine is placed on hold until there is a second call from the first facsimile machine, and during the hold state, it does not accept reception from facsimile machines other than the first facsimile machine.

〔Example〕 Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a proof diagram showing a schematic configuration of an embodiment of the present invention.

As shown in the figure.

First, by making a call from the calling side (first facsimile machine Tt1), the called side (second facsimile machine Tt1)
) receives the Renogar signal and starts receiving it. After starting reception, the called station sends a called station verification signal CED, a non-standard equipment signal N8F, a called subscriber identification signal C8I, and a digital identification signal DIS to the calling side. The calling side starts transmitting after confirming the called station verification signal CED, and subsequently receives the non-standard equipment signal NSF and the called subscriber identification signal e.
sI.

The digital identification signal DIS is analyzed and the transmitted subscriber identification signal TSI and non-standard equipment setting signal NSS are sent depending on the content.
Or send out digital command signal DO8. Subsequently, a training check signal TCP on the outgoing side is sent out. When the called side receives the training check signal TCP normally without any error, it sends the reception confirmation signal CF I (,
The calling side detects this and sends a message MES8.
Send 7ft.

After sending the message, if there is no document to send next, the procedure end signal)】OP is sent, and the receiving side sends the procedure end signal EOP.
After detection, if the message has been received normally, a message confirmation signal MCF' is sent out.

The transmitting side transmits the message confirmation signal MCF and a reception disconnection signal DCN and ends the transmission, and the receiving side receives the disconnection signal DCN and ends the reception.

How to change the destination in the normal procedure as described above will be explained below.

Now, assume that the first facsimile device t1 is transmitting to the second facsimile device 2. The first facsimile device 1 stores the destination number in a storage section (not shown) on the control section lf at the same time as the S/G signal. After that, the procedure progresses and it is assumed that a message is being sent from the first facsimile machine 1 to the second facsimile machine 2. Here, it is assumed that it becomes necessary to urgently transmit a document from the first facsimile machine 1 to the third facsimile machine 3. After this, the first facsimile machine 1 and the second facsimile machine 2
Flowcharts showing the operations are shown in FIGS. 3 and 4, respectively.

In FIG. 3, the first facsimile machine mi which is currently transmitting enters an interrupt mode by pressing an interrupt switch (not shown) on the operation unit 1g (step 4).

When the interrupt switch is pressed in the middle of a certain page of the document being transmitted, an interrupt signal is transmitted after that page is completed. Also, when the button is pressed after the transmission of a certain page is completed (steps 5 and 6).

At that point, an interrupt signal is sent to the second facsimile machine 2 (step 7). Second 7 fuchsia device 12
After receiving the interrupt signal from (step 8),
Immediately disconnect communication with the second facsimile device t2 and N3
(Step 9). The operator here removes the remaining document that was being sent to the second facsimile device f2 from the sending document table of the first facsimile device 1, and then sends it to the third facsimile device f2.
Place the original to be sent to 3 and send it using normal operation.

After communication with the third facsimile device 3 (step 1)
0) Place the remaining original document being sent on the transmission document table to be sent to the second facsimile machine 2, and press the transmission switch (not shown) on the operation unit 1g. By pressing this transmission switch, the first facsimile machine 1 calls the second facsimile machine 2 stored in advance (step 11) and resumes message communication (step 11).
Step 12).

The second facsimile machine it2 during the above-mentioned operation
The movement will be explained with reference to FIG.

The second facsimile device 2 is connected to the first facsimile tJ.
Upon receiving an interrupt signal from the I device 1 (step 13), the interrupt receiver transmits a signal indicating that the interrupt has been accepted to the first 7 axis device 1 (step 14). After receiving the interrupt signal, it enters the hold mode (step 15). Thereafter, the holding mode 1 continues until the first facsimile machine 1 is activated.

During the hold mode, reception from other than the first facsimile machine is not sent or received, such as a busy signal that does not indicate the reception (step 16). Communication is restarted by a second call from the first facsimile device rIL1, and the process returns to step 17) normal transmission. First facsimile attachment gi.

The second facsimile machine [2] stores the destination number and various procedures from the start to the end of communication. These stored numbers are used, as described above, in the first facsimile machine 1 to call the facsimile machine 2 of the cylinder 2 after returning from the interrupt mode, and in the second facsimile machine, when a call occurs during the hold mode. When the caller's number is compared with the stored destination number (first facsimile fcttl), it is used to reject calls other than those from the first facsimile machine 1. . These stored destination numbers and procedures are cleared after the end of communication.The communication procedure when an interrupt mode is added is shown in FIG. As explained above, when an interrupt occurs, the first facsimile device 1 waits until the message on that page is finished, and then
Sends an interrupt signal. still.

The second facsimile device 2 receives the second non-standard equipment signal NSF.
Indicate that the facsimile device is an interrupt-enabled device. After receiving the interrupt acceptance signal - disconnect. During this time, communication is carried out with the 37th facsimile station 1%, and after the first communication is completed, the second facsimile station 2 is called again to resume message communication. These series of movements are controlled by the microprocessor of each device.

According to the present invention, the communication time between the first facsimile and the third facsimile in the 1-interrupt mode is desirably shorter than the width of a sheet of paper, and desirably several sheets of originals.

〔Effect of the invention〕

As explained above, the present invention eliminates wasted time such as waiting time by providing a facsimile machine with an interrupt mode and a hold mode, and enables urgent documents to be sent preferentially.

Moreover, the return is carried out promptly, which has the effect of eliminating wasted time due to the return.
