Abstract

PURPOSE:To eliminate the need for the intervention of the operator by providing a communication control section having a function deciding whether a procedure end signal is sent based on the information of presence of original in an initial identification signal to transit to the call interruption or a message end signal is sent to continue the call. CONSTITUTION:When a call comes from an opposite terminal equipment, a communication control section 5 sends an initial identification signal including the presence information of a sent original based on the information of an original detection signal 7 representing the presence of the sent original informed from an original read section 1 in the called terminal equipment. On the other hand, the caller equipment uses the communication control section 5 to send a procedure end signal and to cut off the call when is discriminated that there is no sent original in the called terminal equipment according to the information of the presence of sent original in the called terminal equipment indicated in the initial identification signal received already when the transmission of the original is all finished.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a group 3 facsimile communication control method, and more particularly to reverse transmission of a document.

BACKGROUND OF THE INVENTION Conventionally, in this type of facsimile, after transmitting a document with a single telephone call, it is identified that there is a document to be transmitted to the terminal to which the document was sent, without operator intervention, and the document is sent to the other party's terminal. There was no function to retrieve (receive) manuscripts in case of such a situation.

Problems to be Solved by the Invention In the conventional facsimile described above, when an original is sent to the other party's terminal and then another original is attempted to be retrieved (received) from the other party's terminal. Make a call request to the other party, reverse the transmission rights with operator intervention and pick up another document, or disconnect the call after sending the document, make a call again, and poll the other party's terminal. was going on.

That is, after transmitting a document during one telephone call without operator intervention, the document could not be retrieved from the other party's terminal.

In addition, some devices automatically start a polling sequence after the original has been sent, regardless of whether there is a document to send to the other device. When there was no document to be processed, extra time was required to disconnect the telephone call, causing an invalid hold.

The present invention has been made in view of the above-mentioned conventional situation,
SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a new facsimile apparatus which makes it possible to solve the above-mentioned problems inherent in the conventional technology.

Means for Solving the Problems In order to achieve the above object, the facsimile apparatus according to the present invention detects that a transmission document is in the document stacker, L, and transmits information on whether the document is present or absent to a communication control section described later. A function that notifies the presence/absence of the document in the initial identification signal (01S) when a call is received from the other party's device, and a function that sends the document after the document has been sent to the other party's device. The call is disconnected by sending an end-of-procedure signal (EOP) based on the document presence/absence information in the initial identification signal (Dis') received before starting the process (Phase E).
and a communication control unit having a function of determining whether to proceed to call continuation (phase B) by sending an end-of-message signal (EOM).

Embodiment Next, a preferred embodiment of the present invention will be specifically explained with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of a facsimile apparatus according to the present invention.

Referring to FIG. 1, reference number 1 is a document reading section, 2 is an encoding section, 3 is a recording section, 4 is a decoding section, 5 is a communication control section,
6 is a line control unit, and 7 is a document detection signal.

8.9.10 indicates an image information transfer path, and 11 indicates an image information 1 communication control procedure signal transfer path.

FIG. 2 illustrates the document reversal transmission control and communication control procedures performed according to the present invention.

When an incoming call is received from the other party's terminal, the communication control section 5 of the called terminal uses the information of the document detection signal 7 indicating whether or not there is a transmitted document notified from the document reading section 1 in FIG. , sends out an initial identification signal (DIS) containing information on whether there is a document to be transmitted.

This initial identification signal (DIS) is shown in FIG.

On the other hand, in the calling device, the communication control unit 5 shown in FIG.
When all the originals have been sent, the information shown in Figure 2 is sent according to the information on whether or not there is a original to be sent at the called terminal, which is indicated in the initial identification signal (DIS) already received as described above. As shown in the figure, if it is determined that the called terminal does not have a transmission document, an end-of-procedure signal (EOP) is sent and the call is disconnected, but if it is determined that the called terminal has a transmission document, The message end signal (ROM) is sent, the message procedure is restarted, the polling procedure specified in the Group 3 facsimile control procedure is activated, and the transmission right is reversed, so that the document cannot be received from the called terminal. Control as possible.

The object of the present invention can be achieved by performing the above control procedure in each of the calling and called communication control units.

DETAILED DESCRIPTION OF THE INVENTION According to the present invention, the initial identification signal (DIS) sent from the called terminal indicates whether or not there is a document to be transmitted to the called terminal, and the calling terminal side , by transmitting an end-of-procedure signal (EOP) according to the information indicated in the initial identification signal (DIS) after sending the transmission document, if the information indicates that there is no document to be transmitted. The call will be disconnected, but if the information indicates that there is a document to be sent, a message end signal (
ROM) and start the premessage procedure,
By executing the polling procedure specified in the Group 3 facsimile control procedure, when there is a document to be sent to the other party's terminal, the operator can start the polling sequence after completing the transmission of the original, and the operator can receive the document from the other party's terminal. without intervention and within the same telephone call.

Claims (1)

[Claims] A facsimile machine that complies with the CCITT Group 3 standard has a document reading section that can detect that the document to be sent is on the document stacker and transmit information on whether the document is present or absent to the communication control section described later, and a device that receives a call from the other device. A function to notify information on whether the document exists or not in the initial identification signal (DIS) when the document is present or not in the initial identification signal (DIS) received after the transmission of the document to the other device is completed and before the transmission starts. The call is disconnected by sending an end-of-procedure signal (EOP) based on the presence/absence of the document (phase E).
a communication control section having a function of determining whether to proceed to call continuation (phase B) by sending an end-of-message signal (EOM) or to proceed to call continuation (phase B).
