DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication device,
In particular, while exchanging document data by exchanging control signals based on a predetermined transmission control procedure in response to an incoming call from the calling side device, the document data corresponding to each document number is stored in a memory in advance. After receiving the call, the DTMF is transmitted from the calling side device before shifting to the predetermined transmission control procedure.
The present invention relates to a communication device for reading out document data corresponding to a document number designated by a signal or a DP signal from the memory and transmitting the document data to the calling side device by exchanging control signals based on the predetermined transmission control procedure.

2. Description of the Related Art In a communication apparatus such as a facsimile apparatus, a normal communication mode is such that a calling side transmits document data and a called side receives the document data, but the calling side transmits the document data. Requesting the called side, and the requested called side transmits the document data stored in advance to the calling side,
Communication in a so-called polling communication form may be performed.

In the polling communication mode, a caller receiving document data sends a plurality of documents stored in advance to a callee transmitting document data by a predetermined transmission document designation procedure. In some cases, so-called selective polling is possible in which the called party designates the document data to be transmitted, and the called party selects the designated document data and sends it to the calling party.

As a form of transmission document specification in selective polling, the called party, after receiving a call, gives a caller a "specify document number" to the calling side prior to starting polling transmission of document data. Sends a voice message, hears the voice message, or knows in advance how to specify the document number. The calling user specifies the document number by pressing the dial key, and the specified document number is assigned. There is a form often used in a facsimile information service in which a called party detects a corresponding DTMF signal or DP signal, specifies a transmission document, and transmits the specified document data to a calling party.

[0005] Such a form in which a voice message is transmitted (not essential) and a transmission document is designated by a DTMF signal or a DP signal can provide various people with various information, and is very convenient. is there.

[0006]

However, in such a form of specifying a transmission document by a DTMF signal or a DP signal, the calling user first listens to a guidance by a voice message, and performs an operation according to the voice guidance. Since there is a need to manually input a document number (or a password in some cases if there is no voice guidance), the operation is cumbersome.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and it is possible to flexibly cope with various forms of transmission document designation by a calling user and transmit a designated document to a calling side.

If it is determined in decision 404 that the document number corresponding to the notified document number is in the table 7a (Yes in decision 404), the document corresponding to the document number corresponding to the notified document number in the table 7a is determined. The data is read from the storage memory 8 and sent to the calling side by polling (process 405), the line is disconnected (process 406), and the process ends.

Thus, when a document number is specified in a format unique to the manufacturer by the NSC signal, the specified document can be transmitted to the calling side.

In the judgment 401, when the NSC signal is not received (No in the judgment 401), or in the judgment 40
If the maker codes do not match in step 2 (No in decision 402), the process proceeds to decision 501 in FIG.

In decision 501 in FIG. 11, it is determined whether the digital transmission command signal DTC and the selective polling signal SEP have been received, and if the DTC signal and the SEP signal have not been received (No in decision 501), the timer It is determined whether T1 has timed out (determination 50).
2) If a timeout has not occurred (No in decision 502), the process returns to decision 304 in FIG. 9, but if a timeout has occurred (Yes in decision 502), it is determined that a communication error has occurred and the line is disconnected (step 502). Process 503), end the process

At decision 501, the DTC signal and SE
If the P signal has been received (Yes in decision 501), S
The document number notified by the EP is collated with the document data management table 7a shown in FIG. 3 (process 504). If there is no matching document number (No in decision 506), the line is disconnected (process 504). 508), the process ends.

If it is determined in the determination 506 that the document number corresponding to the notified document number is in the table 7a (Yes in the determination 506), the document corresponding to the document number corresponding to the notified document number in the table 7a is determined. The data is read from the storage memory 8 and polled and transmitted to the calling side (process 507), the line is disconnected (process 508), and the process is terminated.

Thus, when the document number is specified in the G3 facsimile standard form by the DTC signal and the SEP signal, the specified document can be transmitted to the calling side.

As described above, according to the present embodiment, a document number designation mode by a selection signal such as a DTMF signal or a DP signal according to voice guidance, a document number designation mode by a manufacturer-specific NSC signal, or G3 facsimile Even if a document number is designated by the calling side in any of the designated forms of the document number by the standard SEP signal, a document corresponding to the designated document number can be transmitted to the calling side. It is possible to flexibly cope with various document number designation forms on the calling side.
