Abstract

PURPOSE:To attain the transmission without awaiting the end of reception by operating a reception interruption command means when a picture data desired to be sent urgently to a called party to which a picture data is sent during the reception of the picture data, interrupting the reception operation tentatively while the line with the called party is kept connected and sending a picture data to the called party. CONSTITUTION:When a facsimile equipment detects a call signal, a transmission terminal equipment identification signal, a nonstandard function setting signal and a training check signal sent from the caller side are displayed on a display device 10, and a reception preparation acknowledge signal is sent to the caller in a called facsimile equipment. Then a picture data is sent in the unit of pages from the caller and when the succeeding page to be sent exists, a multi-page signal representing it is sent. The called party sends a message acknowledge signal to the caller side to start the transmission and when an original desired to be sent to the opposite party suddenly exists, a reception interruption command key 9 is turned on to stop the reception and the transmission is started based on the output of an original sensor 11.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a facsimile machine, and particularly relates to improvements in image data reception and transmission control in a facsimile machine.

<Prior art> When a facsimile machine is receiving image data from a called party and it becomes necessary to urgently send a document to the called party, conventional facsimile machines stop the receiving operation and disconnect the line. A conceivable operation procedure would be to disconnect the caller and then send the urgent document to the called party, or wait for the line to be disconnected after receiving the received data, then call the called party and send the urgent document. .

In addition, in the above-mentioned operating procedure, it is necessary to reconnect the line after the line with the calling party has been disconnected.
Publication No. 885 discloses that after receiving image data, without immediately disconnecting the line, it is checked whether there is image data to be transmitted to the called party, and the image data to be transmitted is stored in a storage means. A device has been proposed that is capable of transmitting image data to the called party using the connected line.

Among the conventional techniques, there is a method in which the line is disconnected without the caller's permission while image data is being received, and an urgent document is sent to the caller. Even if the message to be called is urgent, it may be extremely rude to the person on the other end of the call. Furthermore, there is a possibility that the remaining part of the image data that has been sent halfway may not be received due to a mistake or the like.

In addition, the method of sending an urgent document after receiving image data is inconvenient if you want to send image data urgently, even if the transmission starts without disconnecting the line with the calling party. . Furthermore, with the method of temporarily disconnecting the line after receiving the image data sent from the calling party, if the calling party is performing broadcast transmission, the other party may be busy, Sending an urgent manuscript will be delayed.

Therefore, the present invention solves the above-mentioned drawbacks of the conventional device, and when it becomes necessary to urgently send a document to the calling party of the image data while receiving the image data, the urgent document can be sent immediately. An object of the present invention is to provide a facsimile device that can transmit image data to other areas and also reliably receive image data that is currently being received.

Means for Solving the Problems> The present invention provides a facsimile device capable of transmitting and receiving image data using a communication line,
Discrimination notification means for identifying and notifying the calling party when image data from the calling party is being received; and reception interruption instructing means; reception control means for temporarily suspending the image data reception operation while keeping the line connected to the calling party in response to an instruction from the means; and after the reception is interrupted;
a transmitting means for transmitting desired image data to the called party; and after the transmission by the transmitting means is completed, the reception control means cancels the suspension of the reception operation, and receives the image data from the called party. The facsimile apparatus is characterized in that it includes an interruption release means for restarting the operation.

Effects> During reception of image data, if there is a document (image data) to be urgently sent to the calling party who is transmitting the image data, the operator operates the reception interruption instruction means. When the reception interruption instructing means is operated, the reception control means temporarily suspends the reception operation while keeping the line connected to the called party, and makes it possible to transmit image data to the called party.

After the transmission of the urgent image data to the calling party is completed, the interruption canceling means cancels the interruption of the receiving operation, so that the receiving operation of the image data from the calling party is automatically resumed.

FIG. 1 is a flowchart showing control operations specific to this facsimile apparatus, that is, the characteristic reception and transmission control operations. Further, FIG. 2 is a diagram showing a signal transmission procedure between the calling side and the called side when transmission and reception control is performed based on the flowchart of FIG. 1.

Next, the control operation in this facsimile machine will be explained in accordance with the flow shown in FIGS. 1 and 2 and with reference to FIG. 3.

First, a paging signal is sent to the facsimile machine according to this embodiment, which is the called party. The facsimile device according to this embodiment (hereinafter referred to as called side facsimile device)
When a ringing signal is detected (step S1), the line is connected to the calling side (step S2), and the CNG signal sent from the calling side is detected, and the functions of the facsimile machine of the called side are activated. Notify the calling party. in particular,
Called terminal identification signal CHD, non-standard function identification signal NSF,
Signals such as a called terminal identification signal C3I and a digital identification signal DIS are sent to the calling side.

In response to this, the calling party sends calling party identification data and the like. Specifically, this data is a transmitting terminal identification signal TSI, a non-standard function setting signal Nss, and an h-learning check signal TCP.

The facsimile machine on the called side displays the contents of the sent TS or NSS on the display 10 so that the operator can confirm it (step S3).

In addition, the facsimile machine on the called side receives the reception preparation confirmation signal CF.
Send R to the calling party. In response, the calling side sends image data PIX page by page. When image data PIX of a new page is sent, if there is a subsequent page, a multi-page signal MPS representing it is also sent.

The called facsimile machine receives one page of image data P.
When IX is received, a message confirmation signal MCF is sent to the calling party to confirm receipt. After receiving the MCF, the calling side transmits the next page of image data PIX to the called side.

In the manner described above, image data is sent from the calling party to the called party's facsimile machine.

In the facsimile machine of the called party, if a document to be urgently sent to the called party occurs while image data is being received, the operator presses the reception interruption instruction key 9 on the operation unit 2. When the control unit 1 determines the ON signal of the reception interruption instruction key 9 (step S4), it interrupts the reception operation (step S5),
Second message confirmation signal M indicating that there is an emergency transmission to the calling party
Send CF2. When the calling side receives MCF2, in response, it sends a non-standard function identification signal NSF, a called terminal identification signal C3I, and a digital identification signal DIs to the called facsimile machine, which inform the functions of the calling side. send. After receiving these signals, the facsimile machine on the called side sends a training check signal TCP to the calling side.
and waits for the receiving preparation confirmation signal CFR to be sent from the calling side.

During this time, the operator sets a document to be urgently transmitted on the reading section 3. The control unit 1 confirms that the original has been set based on the output of the original sensor 11 provided in the reading unit 3 (step S6), and starts transmitting the original (step S7).

In this embodiment, in the case of emergency transmission, the transmission is automatically started when it is confirmed that the document is set in the reading section 3. However, if necessary, the start key (not shown) on the operation section 2 is pressed. Transmission of the document may be started after waiting for the button to be pressed.

When the transmission of the original is started, the image data PIX read by the reading unit 3 is sent from the called side facsimile machine to the calling side facsimile machine.
is sent in page units. When the last page of image data is sent, a procedure end signal EOP indicating the end of transmission is sent.

When the transmission of the emergency document is thus completed and the control unit 1 of the called side facsimile machine determines that the transmission has ended (step S8
), the control unit 1 restarts the operation of receiving image data sent from the calling side (step S9). Resumption of the receiving operation begins upon reception of the second message confirmation signal MCF2 from the calling party.

After all the remaining image data PIX is transmitted from the calling side to the called side facsimile machine, a procedure end signal EO is sent.
P will be sent.

When the called side facsimile machine receives the EOP from the calling side, it determines whether the reception has ended (step 510), sends a message confirmation signal MCF to the calling side, and in response, a disconnection command signal DCN is sent from the calling side. Once the data has been sent, the communication operation ends.

<Effects of the Invention> Since the present invention is configured as described above, when image data is being received and there is a document to be urgently sent to the calling party who is transmitting the image data, The document can be promptly sent to the calling party without waiting for the end of receiving the image data sent from the calling party. Also,
Even if the reception of image data from the calling party is temporarily interrupted, the reception of image data from the calling party will automatically resume after the transmission of the emergency document is completed, so that the calling party will not be able to receive image data. I never lack respect for them.
