Abstract

PROBLEM TO BE SOLVED: To provide facsimile communication equipment capable of reducing a communicating time when transmission of a document becomes impossible after plural selected polling producers are formed. SOLUTION: After transmitting a first document, a called terminal 120 judges the presence/absence of the other documents to be transmitted and in the case of judging the absence of the document, the terminal 120 transmits an EOP signal showing the finish of the procedure to a caller terminal 110 in stead of an EOS signal showing the finish of selection. When the EOP signal is received with a receiving timing with which the EOS signal has to be received originally, a calling terminal 110 informs the operator of the effect and transmits an MCF signal to the terminal 120. The terminal 120 receiving this MCF signal transmits a DCN signal to the terminal 110.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a facsimile communication apparatus represented by a facsimile apparatus, and more particularly, to a facsimile communication apparatus having a multiple selection polling function.

[0002]

2. Description of the Related Art A facsimile apparatus communicates with a partner machine by a communication procedure conforming to the recommendations of the International Telecommunication Union Telecommunication Standardization Sector (ITU-T).
TU-T Recommendation With thirty recommended revisions, for example,
Functions such as confidential communication, relay broadcast communication, and multiple selection polling can also be realized.

[0003] Specific methods for realizing confidential communication, relay broadcast communication, multiple selection polling, and the like using this standardized standard protocol procedure include a SUB (sub address) command and an SEP (selection polling) command. And the like, and these option signals are sent together with standard signals such as DCS (digital command signal) and DTC (digital transmission command).

[0004] As an option signal, a PWD (password) command for password check, a SID (transmitter identification) command or a PSA (polling subaddress) command is newly added.

[0005] Among the standardized functions, the multiple selection polling function is a function that makes it possible to retrieve a plurality of documents by one communication.

The procedure will be described by taking the G3 protocol as an example. First, a line is established between the calling terminal and the called terminal, and the called terminal sets the multiple selection polling capability to "present". A DIS (Digital Identification Signal) command is transmitted to the calling terminal, and the calling terminal notifies the called terminal of a DTC command for performing multiple selection polling and an SEP command for specifying a document (designating a confidential box). I do. This establishes a multiple selection polling procedure.

After establishing the multiple selection polling procedure, the called terminal extracts the document (image information) specified by the SEP command from the documents registered in advance in the terminal itself, and transmits the document (image information) to the calling terminal. . Here, if the document is composed of a plurality of pages, the document is extracted for each page and transmitted to the calling terminal sequentially.

After the called terminal has transmitted the last page of the one document specified by the SEP command to the calling terminal, it transmits an EOS command indicating the end of selection to the calling terminal, so that the next A document retrieval process is performed.

In the next document retrieval process, phase B
The DTC command for instructing the multiple selection polling and the SEP command for instructing the document (next document) are transmitted from the calling terminal to the called terminal 120 in the same manner as the retrieval of the previous document. And the called terminal 120 that has received the SEP command extracts the document (image information) specified by the SEP command one page at a time, and sequentially transmits it to the calling terminal 110.

[0010] Thereafter, when the calling terminal desires to select the next document, the procedure of the phase B is repeated while changing the document specified by the SEP command to the relevant document.

If the selection of the next document is not desired, that is, if the selection of the current document is the last, in order to indicate that there is no additional document selection following the current communication, the current document is selected. Is set in the DTC command transmitted together with the SEP command designating the document, and transmitted to the called terminal.

The called station receiving the DTC command transmits the last page of one document specified by the SEP command received together with the DTC command, and then transmits the EOP
Command to the calling terminal, and then the called terminal
When the CF command is received, the DCN command is transmitted to terminate the communication. Further, the calling terminal receives the DCN command sent from the called terminal and ends the communication.

[0013]

By the way, in the above-mentioned conventional facsimile apparatus (called terminal), if a situation occurs in which a plurality of documents cannot be selected after the multiple selection polling procedure is established. However, even if the next document is instructed by the other party (calling terminal), the instructed document does not actually exist, so that the document cannot be transmitted.

For example, when all documents in another confidential box are deleted during communication, or when documents in another confidential box are polled first due to another communication and there are no more documents, Since there is no document even if the next instruction is made, the called terminal cannot transmit the document.

To cope with this problem, a conventional facsimile apparatus (called terminal) uses ITU-T Recommendation T.30. According to the procedure according to the 30th revised recommendation, the fact that the document cannot be transmitted is transmitted to the other party (calling terminal).

However, in the conventional facsimile apparatus, even if it is known that the designated document cannot be transmitted after the multiple selection polling procedure is established, the ITU-T Recommendation T.30. In the case where communication is performed according to the procedure based on the 30th revised recommendation, a useless procedure must be executed before notifying the other party that the document cannot be transmitted. For this reason, there has been a problem that the communication time becomes longer and unnecessary communication cost is generated.

An object of the present invention is to provide a facsimile communication apparatus capable of shortening a communication time when a document cannot be transmitted after a multiple selection polling procedure is established.

[0018]

In order to achieve the above object, according to the first aspect of the present invention, after a multiple selection polling procedure is established with a calling terminal, the multiple selection polling is sent to the calling terminal. In a facsimile communication apparatus for transmitting a document specified by the above, a storage means for storing a document to be transmitted, and whether or not another document is stored in the storage means during transmission of the document specified by the multiple selection polling And a signal indicating the end of document selection after transmitting the last page of the document being transmitted when the determination unit determines that the other document is not stored. Communication control means for transmitting a signal indicating a command to the calling terminal.

According to a second aspect of the present invention, in the first aspect of the invention, after transmitting the last page, the communication control means replaces the signal indicating the end of selection of the document with the plurality of selected pages. A signal indicating the end of the polling procedure is transmitted to the calling terminal.

According to a third aspect of the present invention, in the facsimile communication apparatus for receiving a document specified by the multiple selection polling from the called terminal after the multiple selection polling procedure is established with the called terminal, When a signal indicating a command different from the signal indicating the end of selection of the document to be originally received is received after receiving the last page of the document specified by polling, notification to notify the contents based on the command to the outside. It is characterized by comprising control means.

According to a fourth aspect of the present invention, in the third aspect of the invention, after receiving the last page, the notification control means substitutes the signal at the reception timing of the signal indicating the end of selection. When a signal indicating the end of the multiple selection polling procedure is received, the end of the procedure is reported to the outside.

[0022]

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

FIG. 1 shows a facsimile apparatus 1 according to the present invention.

As shown in FIG. 1, the facsimile apparatus 100 includes a central processing unit (CPU) 1 for performing control processing of the entire apparatus, a RAM 2 serving as a work area used by a control program, a touch panel, and the like. An operation display unit 3 used for operation, a reading unit 4 for reading a transmission original, a printing unit 5 for recording and outputting received image data on recording paper, encoding, decoding, enlarging, reducing, and the like for image data An image processing unit 6 for performing the above processing, an image storage unit 7 for storing the received image data or the read image data, a system control unit 8 having a program (ROM) for controlling the entire facsimile, a communication control suitable for a digital network ( A communication control unit 9 including a ROM storing a program for performing a G4 communication procedure, for example, a communication control suitable for an analog network. For example, a communication control unit 10 composed of a ROM storing a program for performing a G3 communication procedure, a digital network control unit 11 for controlling a connection to a digital network (for example, an ISDN network), and a low-speed mode and a high-speed mode function. A modem 12 which is a modulation / demodulation device provided, an analog network control unit 13 which is in charge of control for connection to an analog public network and has an automatic transmission / reception function, and line switching control for switching and connecting a plurality of external line interfaces and a plurality of internal communication circuits. Part 1
4. System bus 1 for exchanging data with each other
5 is provided.

The CPU 1 to the digital network communication control unit 11, the analog network control unit 13, and the line switching control unit 14 mutually transmit and receive data via the system bus 15.

When the facsimile apparatus 100 is connected only to an analog network, the communication control section 9 and the digital network control section 11 can be omitted. When the facsimile apparatus 100 is connected only to a digital network, the communication control section 9 can be omitted. The unit 10, the modem 12, and the analog network control unit 13 can be omitted.

The facsimile apparatus 100 is an ITU-
Recommendation T. 30 has a communication procedure compliant with the recommendation in the Recommendation No. 30. By the revision of the recommendation, a standard protocol is newly added to the communication procedure using a command (option signal) such as SUB (sub address) or SEP (selection polling). It can be handled by a procedure.

Here, the outline of the multiple selection polling function, which is one of the communication functions realized by using the SEP command, will be described.

FIG. 2 is an operation conceptual diagram of the multiple selection polling function. As can be seen from FIG. 2, in the multiple selection polling, the calling terminal 110 that has made a call to the called terminal 120 having opened a plurality of function boxes (confidential boxes) to be polled is sent from the called terminal 120 by the SEP command. Is transmitted to the called terminal 120, the DTC command for instructing the multiple selection polling and the SEP command for instructing the confidential box (indicating the document) are transmitted to the called terminal 120, and the DTC command and the SEP command are transmitted. The called terminal 120, which has received the message, searches for the corresponding confidential box based on the SEP command, and transmits the image data of the transmission original registered in advance by the operator in the confidential box to the calling terminal 110. Basically, the procedure is repeated a desired number of times while sequentially switching the designated confidential box.

The control sequence of such multiple selection polling will be described with reference to FIG.

FIG. 3 shows two documents (one document = 1 in this example) by the multiple selection polling using the G3 protocol procedure.
2 shows a general protocol sequence for extracting a page.

After the called terminal 120 receives the CNG (calling tone) signal from the calling terminal 110,
By transmitting an ED (Called Terminal Identification Signal) command to the calling terminal 110, call setting and line establishment are performed (phase A).

When the phase A ends, the phase B
Move to In other words, the establishment of the multiple selection polling procedure is based on the fact that if the called terminal 120 has a document which can be polled a plurality of times, b in the FIF (facsimile information field)
A DIS signal in which the value of each of it9, bit34, and bit47 is set to “1” is transmitted to the calling terminal 110. Here, bit9 = 1 indicates that polling is ready, bit34 = 1 indicates that there is a multiple selection polling capability, and bit47 = 1 indicates that there is a selective polling capability.

Next, when the calling terminal 110 receives a multiple selection polling instruction from an operator or the like, the calling terminal 1
If the values of the above three bits of the DIS command from “20” are all “1”, the value of bit 34 in the FIF is set to “1”.
Is transmitted to the called terminal 120. Here, bit34 = 1 indicates that multiple selection polling is instructed.

The instruction to select a document is made by transmitting an SEP signal in which a confidential box number of a confidential box from which a document is to be taken out together with the DTC signal to the called terminal 120.

The procedure from the transmission of the DCS signal to the transmission of the image information, that is, the procedure from the end of Phase B to the end of Phase C including the transmission of the image information corresponding to the first document, is performed in a usual manner. This is similar to the facsimile sequence.

Next, when transmitting the post message command in phase D, the called terminal 120 issues an EOS signal if the transmitted page (image information) is the last page of the selected document. Transmit to call terminal 110.

Calling terminal 110 that has received this EOS signal
Transmits an MCF (message acknowledgment signal) command to the called terminal 120. As a result, both the calling terminal 110 and the called terminal 120 return from phase D to phase B after the preset time T2 has elapsed, and the calling terminal 110 selects a new document.

Next, when this new document is the last document and no document is selected except for the selected document (in this example, there is no document other than two documents). , The calling terminal 110 sends a DT to indicate that there is no additional document selection following the current communication.
The value of bit 34 of the C command is set to "0"
A TC signal is transmitted to the called terminal 120. In this case, MC
After the time T2 has elapsed since the F signal was transmitted,
A DTC signal will be transmitted.

The subsequent sequence is the same as a normal facsimile sequence. That is, the phase D procedure is executed after the communication from the transmission of the DCS signal to the transmission of the image information corresponding to the second document is performed.

In this case, when the called terminal 120 transmits the post message command, if the transmitted page (image information) is the last page of the selected document,
An EOP signal indicating the end of the procedure is transmitted to the calling terminal 110,
The calling terminal 110 that has received the EOP signal transmits an MCF signal to the called terminal 120. Then, the called terminal 120 transmits a DCN signal to the calling terminal 110, whereby the line is disconnected between the calling terminal 110 and the called terminal 120 (phase E).

Here, a description will be given of control in a case where a situation occurs in which a plurality of documents cannot be selected after the multiple selection polling procedure is established.

As for this control, in comparison, I
TU-T Recommendation Two cases will be described, one in which communication is performed according to a procedure based on the 30th revised recommendation (conventional) and the other in which communication is performed by multiple selection polling according to the present invention.

First, the former control method will be described with reference to the control sequence of FIG.

FIG. 4 shows a protocol sequence when another document (the second document) is deleted while the first document is being taken out in the control sequence shown in FIG. .

For example, if another document (in this example, the second document) is deleted while the first document is being retrieved during the procedure indicated by reference numeral 30 in the sequence of FIG. The SEP signal for instructing the selection of the confidential box (the second document in this example) together with the DCT signal in which the value of bit 34 is set to “0” is CF
When the called terminal 120 receives the time T2 after the transmission of the R (reception preparation completion signal) command, the called terminal 120 receives the document (the second document) designated by the SEP signal. Is determined, but in this case, there is no document in the corresponding confidential box.
An FNV signal for notifying that is transmitted to calling terminal 110. In addition, instead of transmitting this FNV signal,
A DIS signal or a DCN signal may be transmitted.

The calling terminal 110 transmits a DCN signal to the called terminal 120, so that the line is disconnected between the calling terminal 110 and the called terminal 120.

As described above, in the conventional multiple selection polling, the timing at which the called terminal 120 notifies the calling terminal 110 that there is no document to be transmitted is the timing for instructing the retrieval of the second document. This is when a DTC signal is received.

Next, a control method in communication by multiple selection polling according to the present invention will be described with reference to a control sequence in FIG.

FIG. 5 shows a protocol sequence in a case where another document is deleted while the first document is being taken out, as in the example shown in FIG.

In this example, the same processing as the control sequence shown in FIG. 4 is performed until the processing of transmitting the first document. Next, after transmitting the image information corresponding to the first document, the called terminal 120 determines whether there is any other document to be transmitted, and determines that there is no document to be transmitted. , EO indicating the end of the procedure instead of the EOS signal
The P signal is transmitted to the calling terminal 110.

In this case, the timing of notifying that there is no document to be transmitted is the time when the post message command for the first document is transmitted.

Then, in the calling terminal 110, the EOS
If the EOP signal is received at the reception timing at which the signal should be received, the operator is notified of the fact and the MOP signal is received.
A CF signal is transmitted to the called terminal 120. The called terminal 120 receiving this MCF signal sends a DCN signal to the calling terminal 11.
0 to the calling terminal 110 and the called terminal 1
20 is disconnected from the line.

In this embodiment, the calling terminal 110 itself may be normally terminated. However, since the operator expects that a plurality of documents can be taken out, the calling terminal 110 must be able to retrieve the document. Is notified to the operator that a plurality of documents could not be retrieved. As a notification to the operator, for example, message information “Plural selection polling has been interrupted. Check with the partner operator” is displayed on the operation display unit 3.

As described above, in the control sequence shown in FIG. 5, at least the time T shown in FIG. 4 can be reduced as compared with the control sequence shown in FIG. Specifically, the time can be reduced by about 8 seconds.

Next, the processing operation of the facsimile apparatus 100 capable of shortening the communication time will be described with reference to FIG. 6 and FIG.

FIG. 6 is a flowchart showing the processing operation of the calling terminal 110 to which the facsimile apparatus 100 (see FIG. 1) is applied. FIG. 7 shows the processing operation of the called terminal 120 to which the facsimile apparatus 100 is applied. It is a flowchart shown.

First, the processing operation of the calling terminal 110 will be described with reference to FIG.

As shown in FIG. 6, in the calling terminal 110, the operator operates the operation display unit 3 to input a confidential box number of a desired confidential box, and then starts multi-selection polling (confidential transmission). (Step 201). Here, for example, it is assumed that the confidential box numbers “001” and “002” are selected and the polling reception button is pressed. Note that the confidential box number and the indication of multiple selection polling are stored in RAM.
2 is stored.

By this operation, for example, the communication control unit 10
Sends a dial-out to the other party (called terminal 120) accommodated in the analog network via the modem 12, the line switching control unit 14, and the analog network control unit 13, and establishes a line with the called terminal 120. Is successful (phase A), the process shifts to phase B and waits for reception of a signal from the called terminal 120.

In this signal waiting state, the communication control unit 1
0 determines whether or not the DIS signal transmitted from the called terminal 120 has been received (step 202), and if not received, waits until the DIS signal is received, while receiving the DIS signal. If so, it is determined whether or not all the values of bit9, bit34, and bit47 of the DIS command are "1" (step 203).

If the values of the above three bits are not all "1", the communication control unit 10 executes normal polling communication processing (step 204).

On the other hand, when the values of the three bits of the DIS command are all “1”, the communication control unit 10
Based on the confidential box number stored in AM2 and the fact that multi-select polling is instructed, the DTC signal in which the value of bit 34 is set to “1” and the confidential box number “0”
01 is set to the called terminal 120 (step 205), and the fact that the multi-selection polling mode is being performed is stored in the RAM 2 (step 20).
6).

Next, the communication control section 10 shifts to phase C and executes the image information receiving sequence (step 2).
07). In the image information receiving sequence, the image information of the document stored in the confidential box corresponding to the confidential box number set in step 205 is transmitted from the called terminal 120.
No. 0 receives the image information and stores it in the image storage unit 7.

When the reception sequence of the image information has been completed (when the image information corresponding to the last page of the document has been received), the communication control unit 10 shifts to phase D and is transmitted from the called terminal 120. It is determined whether or not an EOS signal has been received as a post message command (step 208).
It is determined whether an EOP signal has been received (step 20).
9).

If no EOP signal is received in step 209, the process returns to step 207 and the steps after this step are executed. In this example, steps 207 to 209
Is repeated for the confidential box number “00”.
This is when receiving a multi-page document stored in the confidential box corresponding to “1”.

The reason why the communication control unit 10 receives the EOP signal in step 209 is that the called terminal 12 receives the EOP signal during the execution of the image information receiving sequence in step 207.
0, for example, when a document is deleted and there is no more document to be sent next (this is event 1), or when all documents are received in the process of step 207 (this is event 2) Is.

Further, when the EOS signal is received in step 208, the communication control unit 10 executes a process of receiving the next document (step 210). This step 21
0 is executed when the image information received in step 207 is the image information corresponding to the last page,
This is the case where the instruction for the next document is given (in this example, the confidential box number “002” is given).

In the processing for receiving the next document in step 210, the processing in steps 205 to 209 is executed. At this time, of the DTC signal and the SEP signal transmitted in the process of step 205, the SE
In the P command, the confidential box number of the confidential box in which the next document to be selected is stored (in this example,
The confidential box number “002” is set.

For the DTC command in step 205, when N documents (that is, N confidential boxes) are specified in step 201, the next document to be received is "2- (N-1)". )), The value of bit 34 is set to “1”. On the other hand, if the next document to be received is the Nth document, the communication (1 to N B) to indicate that there is no additional document selection following
The value of it34 is set to “0”.

In this example, the confidential box number “00”
Since two confidential boxes of “1” and “002” are specified, at the time of processing in step 210, the SEP command indicating the confidential box number “002” and the bi
The DTC command in which the value of t34 is set to “0” is transmitted.

When the value of the bit 34 of the DTC command is set to "0", the fact that the multi-selection polling mode stored in the RAM 2 is in effect is cleared.

By the way, the communication control unit 10 determines in step 2
If the EOP signal is received in step 09, it is determined whether or not the fact that the multi-select polling mode is being performed is stored in the RAM 2 (step 211). Is determined to be the above event 2 (all documents have been received), and the processing operation of the multiple selection polling procedure is terminated. On the other hand, if the multi-selection polling mode is stored, It is determined that this is event 1 (when there is no more document to be sent to the called terminal), and the event is said to be event 1, for example, "Multiple polling has been interrupted. Check with the destination operator." Is displayed on the operation display unit 3, and then the processing operation of the multiple selection polling procedure is terminated.

In this example, when this processing is completed, the document in the confidential box corresponding to confidential box number “001” is received, but the document in the confidential box corresponding to confidential box number “002” is received. Has been deleted at the called terminal 120, and thus has not been received.

Next, the processing operation of the called terminal 120 will be described with reference to FIG.

When there is an incoming call (step 301), the communication control unit 10 determines whether a plurality of confidential boxes are opened in the image storage unit 7 and whether documents are stored, that is, whether a plurality of documents can be selected. It is determined whether or not it is (step 302).
Here, the confidential box numbers “001”, “0”
It is assumed that documents are stored in the confidential boxes corresponding to each of "02."

If a plurality of documents can be selected in step 302, the communication control unit 10
Each value of t9, bit34, and bit47 is set to "1" (step 303), and the DIS signal is transmitted to the calling terminal 110 (step 304).

After transmitting the DIS signal, communication control section 10 determines whether or not a command from calling terminal 110 has been received (step 305). If no command has been received, communication control section 10 waits until a command is received. On the other hand, if a command is received, it is determined whether the command is DTC (step 306).

The communication control unit 10 determines that the received command is
If it is not a TC command, a normal reception process according to the content of the command is executed (step 307).
If the received command is a DTC command, the DTC command
It is determined whether the value of bit 34 of the command is “1” (step 308).

Here, bit 34 of this DTC command
Is not "1" (when the value is "0"), a normal polling process is executed (step 309).

If the value of the bit 34 of the DTC command is “1” in step 308, the communication control unit 10 analyzes the SEP command received at the same time as the DTC command, and transmits the SEP command from the image storage unit 7 based on the analysis result. A document to be selected is selected (step 310). In this example, S
The confidential box corresponding to the confidential box number (for example, confidential box number “001”) set in the EP command is selected.

Then, the communication control section 10 executes a transmission sequence of image information including a process such as a read process for a document in the selected confidential box (step 31).
1) Thereafter, it is determined whether or not the transmission of the image information for all pages of the document (that is, the image information of the last page) has been completed (step 312). Steps 311 and 312 are repeated until image information for the page is transmitted.

Here, during transmission of image information in step 311, the confidential box number “00” is set by the operator.
It is assumed that the document in the confidential box corresponding to “2” has been deleted.

Next, when the transmission of the image information for all pages is completed in step 312, the communication control unit 10 determines whether there is any other document that can be transmitted, that is, at least one of the confidential boxes. It is determined whether or not the documents in the box are stored (step 313).

Here, if there is a document that can be transmitted,
After transmitting the EOS signal to the calling terminal 110 (step 314), the communication control unit 10 executes a transmission process of the next document (step 315). That is, steps 305 to 305
313 will be performed. In this case, in step 309, the confidential box corresponding to the confidential box number set in the newly received SEP command is selected.

On the other hand, if there is no other document that can be transmitted in step 313 because the document in the confidential box is deleted or the like, the communication control unit 10 sends an EOP signal indicating the end of the procedure to the calling terminal. The data is transmitted to the terminal 110 (step 316), and the processing operation of the multiple selection polling procedure ends.

In this example, the confidential box number “001”
While the document in the confidential box corresponding to the confidential box is being transmitted, the document in the confidential box corresponding to the confidential box number “002” is deleted, and no document exists in any other confidential box. After the document in the confidential box corresponding to "001" is transmitted, the EOP signal is transmitted.

In the above embodiment, communication with the analog network has been described. However, the same control can be performed by the communication control unit 9 on the premise of communication with the digital network.

The present invention is not limited to a facsimile apparatus, but is applicable to all facsimile communication apparatuses capable of executing a facsimile communication procedure, such as a multifunction machine having a facsimile communication function and a copying function.

[0089]

As described above, according to the present invention,
If it is determined that the document to be sent next is not stored after the multi-selection polling procedure has been established with the calling terminal, the transmission of the last page of the already instructed document indicates the end of document selection. Since a signal indicating a command different from the signal is sent to the calling terminal, there is no needless procedure to notify the calling terminal that there is no document that can be sent even if there is a document instruction after that. It is not necessary to do so, and it is possible to reduce the communication time and the communication cost when the document cannot be transmitted after the multiple selection polling procedure is completed.

In particular, according to the present invention, it is determined that the document to be transmitted next is not stored, and after transmitting the last page of the already designated document, the signal is transmitted in place of the signal indicating the end of selection of the document. Since the signal indicating the end of the multiple selection polling procedure is transmitted to the calling terminal, the calling terminal can shift to the disconnection procedure immediately after the timing of receiving the signal indicating the end of the document selection, and can transmit the document. Compared with the case of ending the multiple selection polling procedure using the signal indicating the end of the selection, the time until the end of the procedure can be greatly reduced.

Further, according to the present invention, after the multiple selection polling procedure is established with the called terminal, after the last page of the already designated document is received from the called terminal, the selection of the document to be originally received is performed. When a signal indicating a command different from the signal indicating the end is received, the contents based on the command are notified to the outside.

In particular, in the present invention, after receiving the last page, a signal indicating the end of the multiple selection polling procedure is received instead of the signal at the reception timing of the signal indicating the end of selection of the document to be originally received. At the time, the end of the procedure is notified to the outside.

According to this configuration, after entering the multiple selection polling, the operator of the own terminal, which is the requester of the multiple selection polling, is notified without delay that there is no document available for transmission at the called terminal. It is possible to restrict unnecessary document instructions thereafter, and to quickly respond to a recovery operation such as contacting the called terminal for status confirmation.
