Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication terminal having a binary file transfer (volume transfer) function, and more particularly to a communication terminal which uses binary file transfer to transfer a volume of a floppy disk.

[0002]

2. Description of the Related Art Communication terminals such as facsimile machines for transmitting and receiving information such as image information files and characters of document files stored in a floppy disk (hereinafter referred to as FD) have been conventionally known (for example, Japanese Unexamined Patent Application Publication No. Hei 10 (1999) -242977). 7-288
665, JP-A-7-7577). In addition, as an international regulation, ITU-T T. 30 recommended DIs
BFT (Binary File Transfer Bit) added to S / DTC / DCS and ITU-T T.264. The 434 recommendation (regulation of binary file transfer bit for telematic service) and the like are also known techniques. Here, the conventional transmission and reception of binary image information will be briefly described.

FIG. 14 is a diagram for explaining a conventional protocol when transmitting and receiving binary image information. In the figure,
NSF is a non-standard function identification signal, DIS is a digital identification signal, DCS is a digital command signal, NSS is a non-standard function setting signal, TCF is a modem training signal, CFR is a reception ready signal, PIX is image information, PPS. EOP is a procedure end signal (at the time of ECM), MCF is a message confirmation signal, DCN is a disconnection command signal, the left side is the transmitter side,
The right side shows the receiver side.

The transmitter analyzes the digital identification signal DIS sent from the receiver side to determine the transmission mode.
In this case, there is a constraint that the mode of the capability (function) that the receiver side does not have cannot be set. However, it is possible to arbitrarily select the capability of the receiver side. In the transmitter, when the mode is selected, the receiver side is notified by the digital command signal DCS. The determination of the transmission mode in this case is performed without the user's awareness, and the digital command signal DCS is selected.
It was printed on the recording paper on the receiver side regardless of the contents of. In the case of special communication such as confidential transmission, printing is not performed on the receiver side unless a preset procedure is executed after reception.

By the way, in the standard mode BFT, the FD
During the transfer of the (floppy disk) data, the receiver side can notify the presence or absence of the function transmitted from the transmitter side (the 53rd bit of the digital identification signal DIS).
On the other hand, on the transmitter side, the receiver has the same function, and when BFT transmission is performed, only that effect is instructed (the 53rd bit of the digital command signal DCS). Subsequent detailed attributes are incorporated in the image information PIX. In this case, this attribute is treated as binary data.

That is, the transmitter is shown as an attribute of BFT information to be transmitted, and there is no function or means for notifying the transmitter side of detailed functions of a received image such as a specific receivable format type. Therefore, when the FD data is transferred by the BFT from the transmitter side, the read FD format type is designated as the attribute as described above. However, in such a system, the intention of the receiver side is not reflected in the communication, so that the data is transmitted in an appropriate format type selected by the transmitter side. As a result, in the case of binary image information transmission, printing is possible regardless of the reception mode and can be easily read by the user on the receiving side. When FD data of a format type that is not owned by the machine is transmitted, the data cannot be taken out immediately. In addition, ITU-T T. The 30 Recommendations specify a group 3 facsimile apparatus for document transmission with an error correction function. By executing the ECM procedure according to this regulation, it is possible to transmit error-free image information even if the line quality is poor.

[0007]

As described in the prior art, the FD controller (hereinafter abbreviated as FDC).
With a communication terminal having a communication function based on a file transfer procedure (hereinafter referred to as a BFT function), FD data can be transmitted and received. However, a communication terminal equipped with an FDC capable of handling FDs of a plurality of format types and a BFT function is not provided with means for notifying the transmitter of the detailed function related to the FD document at the time of reception. Therefore, even if an FD document with a different format type is received, the FD data cannot be retrieved quickly and easily.
There is a problem.

When transmitting binary image information, the facsimile apparatus can always print an image on a recording paper regardless of the receiving mode. On the other hand, in the transfer of FD data, the printing of an image on such a recording sheet is performed by the F
This corresponds to writing to D. However, when sending FD data of a format type that the receiving side does not have,
Even if the FD document is transmitted, there is a problem that the receiving side cannot easily take it out. For example, it is necessary to check the format of the received FD data and initialize the FD in the format by an external device or the like. Moreover, even if the data is written in the FD thereafter, it is assumed that the operability (business) after that is not good.

According to the present invention, in a communication terminal having an FDC capable of handling FDs of a plurality of format types and a BFT function, it is possible to notify the other party of the FD format type capable of being handled by itself when receiving the FD data. An object of the present invention is to prevent useless communication caused by different format types (the inventions of claims 1 to 6). Even in a communication terminal that can handle FDs of a plurality of format types, each user normally uses only the FDs of a specific format type. Therefore, secondly, it is possible to notify the other party of only the format type that the user on the receiving side wants to use, and the F of the received BFT is sent.
An object of the present invention is to make a D document available quickly and easily (the invention of claim 2).

Third, when there are a plurality of format types that the receiving side user wants to use, it is an object to improve the convenience of the receiving side user by preferentially selecting the most preferable type. Invention of 3). Fourth,
For the other party who once communicated, the FD format type information obtained by the communication is
An object of the present invention is to prevent erroneous operation and the like by holding the FD format information that is frequently used and setting it automatically during subsequent communication (the invention of claim 4).

Fifth, from the viewpoint of routine work and the like, the FD that can be received by the communication terminal described in the second problem above.
It is an object of the present invention to ensure that the FD document of BFT received from an important destination can be taken out by making it possible to switch the format type of the above for each destination (the invention of claim 5). Sixth, similarly, from the viewpoint of routine work and the like, with respect to the communication terminal described in the fifth subject, it is an object to make it possible to switch the format type of the FD that can be received by only a specific destination ( Claim 6
Invention).

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of a communication terminal having a BFT function of the present invention will be described in detail with reference to the drawings. The first to fifth embodiments will be described below. The invention of claim 1 described in the first embodiment is the basic invention, and will be described in the second to fifth embodiments, respectively. The inventions of claims 2 to 5 are based on the invention of claim 1. First, the hardware configuration common to all the embodiments, that is, the BF of the present invention
A communication terminal having a T function will be described.

FIG. 1 is a functional block diagram showing an example of an embodiment of the main configuration of a communication terminal having a BFT function of the present invention. In the figure, 1 is a system control unit, 2 is a system memory, 3 is a scanner, 4 is a plotter, 5 is a BFT control unit, 6 is an FD control unit, 7 is a network control unit, 8 is a G3 FAX modem, 9 is an image memory, Reference numeral 10 is an encoding / decoding unit, 11 is an operation display unit, and 12 is a system bus.

The communication terminal having the BFT function shown in FIG. 1 is basically the same as the conventional device except that the system control unit 1 controls according to the flow shown in FIGS. It is the structure of. The function of each part is as follows. The system control unit 1 uses the communication terminal of FIG.
In addition to performing the control processing of each unit and the facsimile transmission control procedure similar to the conventional apparatus, it has a function of performing the control unique to the present invention described later. The system memory 2 is used as a work area when the system control unit 1 executes a program, and stores necessary data and the like, and further stores parameters and user registration data necessary for the system. It is a means.

The scanner 3 is an image reading means for reading an original at a predetermined resolution. The plotter 4 is an output unit such as a printer that records and outputs images or reports at a predetermined resolution. The BFT control unit 5 uses the FD
It is a format control means having a function of adding header information to the data of BFT format to be BFT formatted or unformatted at the time of reception. The FD control unit 6 is a control unit including a general-purpose FDD / FDC. Network controller 7
Is a control means for connecting to a public telephone line network, and also has an automatic calling / receiving function.

The G3 FAX modem 8 has a function of realizing the modem function of G3 facsimile, and has V17, V
33, V29, V27fer, FSK mode and the like. The image memory 9 stores image information at the time of memory transmission and memory reception (proxy reception, confidential reception, etc.), and a FIFO or EC for G3 (group 3) communication.
The storage unit is also used as an ECM buffer during M (automatic error resending function) communication, a line buffer that handles raw image data (image information before encoding) in units of lines, and the like. The encoding / decoding unit 10 has a function of encoding and compressing raw image data (image information before encoding) according to a predetermined method, and expanding the encoded image to original raw image data. is doing. The operation display unit 11 is composed of various keys provided on the panel, a display LCD, an LED and the like, and has a function of performing a communication operation and a registration operation. The communication terminal having the BFT function of the present invention is configured as described above in all the embodiments.

By the way, as described above with respect to the prior art, the ITU-T. If a group 3 facsimile apparatus for document transmission with an error correction (ECM) function defined in Recommendation No. 30 is used, it is possible to transmit error-free image information even if the line quality is poor. According to the present invention, the facsimile machine according to this regulation is capable of transmitting image information without error, and instead of the image information, other information, specifically, information such as FD is kept as it is. In this state, or in the state where the encoding processing suitable for the information is performed, the transmission is performed. In this case, in terms of communication procedure, simply performing ECM HDLC framing,
It is characterized in that the MH / MR / MMR method used for image information does not have to be compressed and the passed information is received as it is. That is, in the case of binary transfer, the communication procedure skips encoding and decoding of image information handled in phase C. Regarding coding in this case, ITU-TT. 4 and T.I. It is specified in 6. Therefore, in the communication procedure, the information may be sent and received as it is. In this case, according to the present invention, information indicating the attribute of information called a header of binary information and the like is also put together in the image information portion.

Next, a specific operation will be described. Actually F
When transmitting the information of D, first, the BFT of the receiving side
(Binary file transfer bit) is on (with function)
Check whether or not. And the BFT on the receiving side is on,
When it has a function, the binary information (the data part in the sector of the FD) is taken out by the BFT control part 5 in FIG.
The extraction of the binary information may be performed before the call is made, as in the storage process at the time of memory transmission. Next, the BFT control unit 5 processes into a format to which header information and the like are added, as described above. Then, the processed information is transmitted using the ECM buffer.

At the time of reception, conversely, the BFT control unit 5 on the receiving side decomposes the information in the ECM buffer into header information and actual data. Then, the latter actual data is temporarily stored in the image memory 9 or is directly written into the FD by the FD control unit 6. Needless to say, in the case of a medium having a slow writing speed, it is better to temporarily store the image in the image memory 9 for better system performance. As described above, the BF of the present invention
In a communication terminal having a T function, it is premised that FD volume transfer (so-called whole transfer) is performed using a binary file transfer function. Further, since the FD is a medium that takes time to read / write, the following embodiments assume that the FD is temporarily stored in the image memory 9 before calling. Similarly, at the time of reception, it is assumed that the data is once stored in the image memory 9.

First Embodiment This first embodiment corresponds to the invention of claim 1, but is also related to the inventions of claims 2 to 6,
The invention of claim 1 is a basic invention. In the first embodiment, an FD drive unit (FDC) capable of processing FDs of a plurality of format types and a communication terminal having a communication function according to a file transfer procedure (volume transfer procedure) can perform processing at the time of reception. It is characterized in that the receiver side can notify the transmitter side of the other party of the FD type.

According to the first embodiment, the received FD document of BFT can be taken out without fail. Therefore, in the communication terminal shown in FIG. 1 above, processing is performed by the FDC installed in the communication terminal (transmitter side and receiver side) having this BFT function on the system memory 2 or the RAM in the system control unit 1. Information on the format type of FD that can be created is written in advance. Also, on the receiver side,
The BFT function of the digital identification signal DIS is set, the FD volume transfer function of the BFT of the non-standard function identification signal NSF, and the information held previously, that is, the own FC
All the FD formats are set by citing the information of the FDC format type that can be processed by the D. And
When there is an incoming call, the digital identification signal DIS / non-standard function identification signal NSF is created in consideration of other functions, and the transmitter side is notified. Here, the non-standard function identification signal NSF and the non-standard function setting signal NSS will be described.

FIG. 2 is a diagram showing an example of the bit configuration of the non-standard function identification signal NSF and the non-standard function setting signal NSS. In the figure, bitM is the Mth bit,
nbit indicates an n-bit configuration.

As shown in the NSF of FIG. 2, in the non-standard function identification signal NSF, for example, the M-th bit (bi
tM) is assigned to a bit indicating the presence or absence of the FD volume transfer function of BFT. When the bitM is "1", the transfer function is "present", and when the bitM is "0", the transfer function is "absent". The n bits that follow it indicate the type of FD format that can be processed by the FDC in 1-bit units.

For example, if there are four types of FD format, n = 4 and the bit of the corresponding type is set to "1". The above is an example of the bit configuration of the non-standard function identification signal NSF. Further, the non-standard function setting signal NSS is also the M-th bit (bi
tM) is assigned to a bit indicating the presence or absence of the FD volume transfer function of the BFT. Then, of the following n bits, only the bit corresponding to the format of the FD to be transferred is set to "1". In this FIG. 2, n = 4
Of these, the case where the third bit is "1" is shown.

When the volume transfer operation of the FD is performed in the communication terminal shown in FIG. 1, the transmission of the BFT document is started. This transmission is the transmission of the FD document and also the volume transfer. In this case, if either condition is missing, the normal BFT transmission procedure will be performed. Regarding the function of the other party, the digital identification signal DI
Since the ability can be determined when S is received, the ability is investigated. The BFT function is a digital identification signal DI
When S bit 53 = 1, it is present, and when bit 53 = 0, it is absent. Also, the FD volume transfer function is
When the bit M = 1 of the non-standard function identification signal NSF is present, when the bit M = 0, it is absent. Even if the signal NSF cannot be identified, it is determined that the FD volume transfer function is not provided. Further, when the FD format is invalid (in the n bits from the bit M + 1 of the signal NSF,
Since the bit = 0 of the format information to be transmitted does not make sense to continue the transmission, the interruption procedure is performed.

By judging these conditions, bit M = 1 of signal NSF, bit of the target format in n bits =
When it is 1, the corresponding non-standard function setting signal NSS
Is created and sent to the receiving side. In this case, since the nonstandard function setting signal NSS is used, the nonstandard BFT procedure is performed. With the above control, the FD format type of the FDC on the receiver side can be notified to the transmitter side, so that invalid (not easy to use) FD format type data transfer from the transmitter side can be performed. Avoided. Note that FIG. 2 shows the case where 4 bits (n = 1) are used for the FD format type of the signal NSF and the signal NSS, but if there are more format types, the number of bits is increased. do it. Even if the bit indicating the presence or absence of the BFT function is defined in the signal NSF / NSS in duplicate, no problem will occur. The above processing is shown in the flow.

FIG. 3 is a flow chart showing a main processing flow at the time of transmitting a BFT document in the first embodiment in the communication terminal having the BFT function of the present invention. In the figure, # 1 to # 12 indicate steps.

In step # 1, transmission of the BFT document is started. In step # 2, it is determined whether the document is an FD document. If it is an FD document, the process proceeds to step # 3 to determine whether or not it is volume transfer. As a result of the determination in the previous step # 2, if it is not the transmission of the BFT document, and as a result of the determination in the previous step # 3, it is not the volume transfer, the process proceeds to step # 11 to perform the normal BFT transmission procedure. On the other hand, as a result of the determination made in step # 3,
In the case of volume transfer, the process proceeds to step # 4 to monitor the reception of the digital identification signal DIS. When the digital identification signal DIS is received, the process proceeds to step # 5 to check the capability of the receiver.

At step # 6, it is checked whether or not it has the BFT function. If so, it is checked in next step # 7 whether or not volume transfer is possible. When the volume transfer is possible, it is checked in the next step # 8 whether the FD format is valid. If the FD format is valid, step #
At 9, the non-standard function setting signal NSS is created and transmitted.
Proceeding to the next step # 11, the non-standard BFT transmission procedure is executed.

As a result of the judgment made in step # 6,
When the BFT function is not provided, as a result of the determination made in the previous step # 7, the volume transfer is not possible, and further, as a result of the determination made in the previous step # 8, if the FD format is not valid, go to step # 12. Go ahead and perform the interruption procedure. As described above, in the first embodiment, the FDC capable of handling the FDs of a plurality of format types.
In addition, the communication terminal having the BFT function can notify the other party of the information of the FD format type that can be handled by the communication terminal at the time of reception. Therefore, the transmitted FD data is a format type that can always be used on the receiving side, and useless communication is avoided.

Second Embodiment This second embodiment corresponds to the invention of claim 2, but is also related to the invention of claim 1. In the first embodiment, the configuration in which it is possible to notify the other party of the information of the FD format type that can be handled by the own device at the time of reception has been described, but in the second embodiment,
Furthermore, it is characterized in that the receiving side can notify only the format type that is most easily used.

The hardware structure is similar to that shown in FIGS. 1 and 2. A registration function is provided on the operation display unit 11 as one of the functions to perform registration. For example, it is assumed that when the [Function] key is pressed, the function mode is entered, and when the ten keys [2] and [6] are sequentially pressed, the function No. 26 is entered. Here, in Function No. 26,
If FD format selection is assigned,
The screen as shown in FIG. 4 is displayed.

FIG. 4 is a diagram showing an example of a display screen when the FD format is selected. In the figure, and indicate the format selection screens, respectively.

If the format of the screen shown in FIG. 4 is the type to be used (the type of format to be set), when the ten key [1] is pressed, the item "1: use" is highlighted. When the enter key is pressed in this display state, the format is selected / set.
If you are not using it, press the numeric keypad [2],
The item “2: Do not use” is highlighted. In this way, the format settings are changed by using the ten keys [1] and [2].

When the current settings are acceptable,
The [YES] key is used to perform the next selection operation. When the next selection is operated, the selection screen shown in FIG. 4 is changed to the selection screen shown in. When there is a scroll key, it is possible to switch the selection screen by operating the left and right keys. Further, in this case, the next selection may be the down key, and the up key may be used to return to the previous state. The control for selecting such a format is basically the same as the control for selecting / setting a normal function, and the display example of FIG. 4 is only one example. By the above operation, receivable FD format information is rewritten in the system memory 2 of FIG.

FIG. 5 shows an F that can be used by the communication terminal on the receiving side.
It is a figure which shows an example of the storage state about D format information. In the figure, F1 to F5 indicate the types of FD formats.

In FIG. 5, there are five types of FD formats that can be used, F1 to F5. Of these, the formats used by the user are two types, F1 and F4. Therefore, when receiving, the FD format information to be notified to the other party (sending side) is F1 and F
There are only two kinds of 4. Although illustration of the flow is omitted, it is basically the same as that of FIG. A non-standard function identification signal NSF is created according to the contents of FIG. 5 and is notified to the transmission side by the protocol shown in FIG.

As described above, in the second embodiment, the processing of n bits of the non-standard function identification signal NSF is improved, and instead of notifying all the format types that can be processed by the FDC, the user can Only the format type to be used is replaced with the content stored by the setting operation described in FIG. Therefore, as compared with the method of notifying the format information according to the first embodiment, the BFT FD document received by the receiving side can be taken out without fail, and the subsequent processing becomes easier. In other words, it is possible to avoid the case where the other party is requested to resend in a different format, and it is possible to reduce unnecessary communication costs, and to use the F format that is not normally used.
There is no need for wasteful work such as preparing D and copying it via an HD (hard disk).

Third Embodiment The third embodiment corresponds to the invention of claim 3 but is also related to the invention of claim 1. In the above-described second embodiment, the case where only the format type used by the user is notified has been described. The third embodiment is characterized in that the format types used by the user are prioritized and the information of the format types most easily used is notified.

Also in the third embodiment, similarly, the operation display unit 11 is provided with a registration function as one of the functions to perform registration. For example, it is assumed that when the [Function] key is pressed, the function mode is entered, and when the ten keys [2] and [0] are sequentially pressed, the function number 20 is entered. Here, assuming that the function number 20 is assigned to one-touch registration, the following FIG.
A drawing like is displayed.

FIG. 6 is a diagram showing an example of a display screen at the time of one-touch registration. In the figure, -indicate the selection screens for one-touch registration.

On the screen shown in FIG. 6, if the desired one-touch key is selected, the number and name of the other party can be registered. In addition, if you have already registered,
As indicated by, if "01" of "one touch" is selected, it is possible to quote the registered information such as the destination number and the destination name. The input operation and function of the one-touch registration as described above are well known in the related art, and thus detailed description thereof will be omitted. However, in the third embodiment, registration of the FD format is enabled by the following submenu. ing.

The screens indicated by-in FIG. 6 are FD format registration screens. Here, when there are six types of FD format types, it is possible to register (1: use) with a bit matrix. In addition,
Since the bit matrix is the same as the conventional one, its explanation is omitted. On the screen of Figure 6, "*****"
The display of indicates that the FD format information of the destination has not been input even once. Therefore,
In the screen of FIG. 6, the FD format information has been input to the two destinations. By such an operation, one-touch or shortened information is registered in the system memory 2 (or the RAM in the system control unit 1).

FIG. 7 is a diagram showing an example of a list of registered one-touch and shortened information. In the figure, indicates one-touch and indicates shortened information.

In FIG. 7, the destination number, the destination name,
This shows a state in which FD format information and the like are registered. One touch is 64 pieces from "0" to "63".
The shortened information is the case where 100 pieces of "* 00" to "* 99" can be registered. The information in FIG. 7 can be printed as a list. Also, the F of BFT
When the destination designated at the time of executing the D transfer is the one-touch or shortening shown in FIG. 7, the FD corresponding to the destination
Format information can be quoted.

When the format type (of the FD being used) obtained at the time of reading the FD does not match the FD format information of the destination shown in FIG. 7, that is, when the FD format is invalid for the destination. , The alarm is displayed to inform that effect. By issuing such a warning, it is possible to prevent unnecessary transmission of the BFT document. Also, the FD that is reading
When the format type of and the FD format information of the destination in FIG. 7 match, FD reading is executed,
Send a BFT document.

In the third embodiment, the notification of the possible format type using the non-standard function identification signal NSF from the receiving side is not necessary, and the BFT function is provided by the digital identification signal DIS at the time of checking the receiving ability. It is good if there is. If this BFT function is absent, it will proceed to the interruption procedure. Then, it is confirmed whether the signal NSF can be identified. In this case, the manufacturer code of this signal NSF is quoted to determine whether they are the same manufacturer. If it is confirmed that the signal NSF can be identified, the non-standard function setting signal NSS is sent to execute the non-standard procedure. When the signal NSF cannot be identified, the digital command signal DCS is sent out to execute the standard procedure. The above processing is shown in the flow.

FIG. 8 is a flow chart showing the main processing flow at the time of BFT transfer in the third embodiment for the communication terminal having the BFT function of the present invention. In the figure, steps # 1 to # 6 and # 9 to # 12 indicate steps similar to those in FIG. 3, and # 21 to # 23 indicate added steps.

The flow of FIG. 8 is different in that steps # 21 to # 23 are provided instead of steps # 7 and # 8 of FIG. Then, in step # 6,
Check if it has BFT function. BFT
Step # 21 added when the function is available
Then, it is checked whether the non-standard function identification signal NSF can be recognized. When the non-standard function identification signal NSF can be recognized, the process proceeds to step # 9 similar to FIG.
A non-standard function setting signal NSS is created and transmitted. On the other hand, when the non-standard function identification signal NSF cannot be recognized, the digital command signal DCS is created and transmitted in step # 22. Proceed to next step # 23, and use standard B
Perform the FT transmission procedure.

As described above, in the third embodiment, when there are a plurality of format types that the user on the receiving side wants to use, the most preferable type is selected preferentially, which is convenient for the user on the receiving side. Be improved. Also, when an FD format of a format type that is not used by the receiving user is selected, a warning to that effect is issued.
The inconvenience that the D document is transmitted is prevented in advance.

Fourth Embodiment This fourth embodiment corresponds to the invention of claim 4, but is also related to the inventions of claim 2 and claim 3. In the fourth embodiment, as in the first embodiment, the FD format type available on the receiver side is indicated by the non-standard function identification signal NSF. When a call is made (transmitted or polled received) to the destination using the registered one-touch or shortened information, the format of the FD that can be processed by the FDC shown in FIG. 2 is obtained from the information of the received non-standard function identification signal NSF. N indicating the type of
Read a bit. This is the area of the system memory 2 used in the destination registration described in the third embodiment,
That is, it is held in the storage area of the FD format information.

As described above, if the information obtained from the received non-standard function identification signal NSF is used, not only the registration operation described in the third embodiment above becomes unnecessary, but also the BFT When the designated destination is one-touch or shortened at the time of executing the FD transfer, the learned FD format information can be quoted. Then, these pieces of information are compared with the format type obtained at the time of reading the FD (the format type of the FD currently used). As a result of the comparison, when the two do not match, that is, when the FD format type is invalid for the destination, the alarm is displayed and the FD is not read. By such control, useless BFT transfer can be avoided. In this case, at the time of actual BFT transmission, it suffices to perform only the same control as in FIG.

As described above, in the fourth embodiment, with respect to the other party who has once communicated, the FD format type information obtained by the communication is used for each destination as the FD format information which is frequently used. It is retained as, and can be automatically set at the time of subsequent communication. In addition, the format type F that the other party does not use
When the D format is selected, a warning to that effect is issued. Therefore, the BF of the format that is annoying to the receiver side
Processing that does not handle T FD documents is realized. Furthermore, B
Since the FD document to be FT-transmitted is always in the format owned by the other party, the transmission in the useless format is prevented in advance. For example, in the case of the third embodiment described above, an operation error or the like may occur at the time of setting, but according to the fourth embodiment, such an inconvenience is surely avoided. .

Fifth Embodiment This fifth embodiment corresponds to the invention of claim 5, but is also related to the invention of claim 1. In the fifth embodiment, in the case of routine work and the like, in the communication terminal described in the second embodiment, it is possible to switch the receivable FD format type for each destination. It has features.

Therefore, also in the fifth embodiment, it is assumed that the one-touch / shortening information is stored in the system memory 2 as in the third embodiment. Upon reception, the FD that can be received by the non-standard function identification signal NSF
The format type is not specified. And
When receiving, the other party is instructed that the digital identification signal DIS has the BFT function, and if the non-standard function setting signal NSS instructs the FD transfer of the BFT, this signal N
Reference the FD format in the SS. In this case, when the receiver side determines that the FD format is not desired to be used by itself, the disconnection command signal DCN may be sent from the receiver side after the training signal TCF of the modem.

FIG. 9 is a diagram for explaining the procedure at the time of interruption in the fifth embodiment in the communication terminal having the BFT function of the present invention. Reference numerals in the figure are the same as those in FIG.

The fifth embodiment is a receivable FD.
Since the format type is not specified, FIG.
The non-standard function identification signal NSF shown in FIG. 2 does not need the M-th bit (bit M) shown in FIG. As a result of comparing FD formats,
If they do not match, a disconnection command signal DCN is sent from the receiver side after the modem training signal TCF to disconnect the circuit. The above processing is shown in the flow.

FIG. 10 is a flow chart showing the main processing flow at the time of receiving a BFT document in the fifth embodiment in the communication terminal having the BFT function of the present invention. In the figure, # 31 to # 42 indicate steps.

In step # 31, the reception is started. In the next step # 32, the non-standard function identification signal NSF, the signal C
The IS and the digital identification signal DIS are created and transmitted. In this case, since it has the BFT function, "1" is set to the 53rd bit of the digital identification signal DIS. In step # 33, it is monitored whether or not the digital command signal DCS or the non-standard function setting signal NSS is received. Digital command signal DCS or non-standard function setting signal NSS
Is received, it is checked in the next step # 34 whether or not there is a BFT request. If there is no BFT request, the process proceeds to step # 35 to move to the requested process flow.

On the other hand, when there is a BFT request,
In step # 36, it is checked whether the standard mode (DCS) is set. When not in the standard mode (when the non-standard function setting signal NSS), in the next step # 37,
Check if it is FD volume transfer. FD
When it is not a volume transfer, and the previous step # 36
As a result of checking in step #
Proceed to 38. In step # 38, the normal BFT processing procedure is executed.

On the other hand, as a result of checking in step # 37, if the FD volume is transferred, the process proceeds to step # 39 to check the format. In step # 40, the format check result is determined, and if they match, the process proceeds to step # 41 to move to the flow of the FD volume transfer reception process. If they do not match, in step # 42, after the training signal TCF of the modem, the disconnection command signal DCN is sent from the receiver side, and the flow of FIG. 10 ends.

FIG. 11 is a diagram for explaining the method of checking the format on the receiving side in the fifth embodiment of the present invention. In the figure, indicates the FD format information area in the system memory 2.

FIG. 11 shows the format check method performed in step # 39 in the flow of FIG. The receivable FD format type stored in the FD format information area in the system memory 2 shown in FIG. 11 is compared with the n bits of the non-standard function setting signal NSS shown in FIG. Note that FIG. 10 shows the flow on the receiving side, but the flow of transmission is almost the reverse of that on the receiving side, so illustration is omitted. The above is the case where the system on the receiver side has only one receivable FD format information, as in the first embodiment.

In the fifth embodiment, it is also possible to use the signal sent from the transmitter side. That is, the signal TSI or the signal RT sent from the transmitter side
It is investigated whether I (corresponding to TSI in the non-standard procedure) and the registered destination match, and if they match, the receivable FD of the destination can be received as in the case of the third embodiment.
Compare with the format. Specifically, regarding the contents of the non-standard function setting signal NSS (or signal TSI) sent from the transmitter side and the list of registered one-touch and shortened information shown in FIG. The destination number / destination name of the abbreviated information is compared, and when they match, the FD format information corresponding to that is compared,
The receivable FD format type stored in the FD format information area shown in FIG. 11 is compared. In the flow of FIG. 10 described above, such a format check is executed in step # 39.

Also in the case of this method, if it is desired not to use this FD format, the disconnection command signal DCN is received from the receiver side after the training signal TCF of the modem.
Is sent. As described above, in the fifth embodiment, the receivable FD format type can be switched in units of destinations in the case of routine work. Therefore, as in the first to fourth embodiments, the inconvenience that the FD document of the BFT received from the important partner cannot be taken out is prevented. As a result, useless communication costs on the other side are also saved. At the same time, it is possible to prepare a formatted FD and avoid waste such as execution of copying via the HD or the like.

Sixth Embodiment The sixth embodiment corresponds to the invention of claim 6 but is also related to the inventions of claim 2 and claim 5. In the second and fifth embodiments described above, it is necessary to assign individual areas to the information of one-touch or abbreviated registration destinations, which is not always efficient. In the sixth embodiment, attention is paid to the fact that the number of destinations using the BFT is practically limited to a certain number, and in addition to the destination information, the fifth embodiment described above is used on the system memory 2. Information of a registered destination group having a BFT function for comparison with the signal TSI and the signal RTI described in the above form is registered. Generally, F
The number of D format types is smaller than the number of registered destination group information. Therefore, the destination information of the same FD format is registered in the information of each FD format type. At the time of transmission, the system memory 2 is saved by comparing with this information, and the same effect as in the case of the fifth embodiment can be obtained. Also in the sixth embodiment, the procedure at the time of interruption is the same as that in FIG. 9 described in the fifth embodiment. The processing flow is also the same as in FIG. 10, but the method of checking the format performed in step # 39 is slightly different.

FIG. 12 is a diagram for explaining a format check method performed on the receiving side in the sixth embodiment of the present invention. In the figure, indicates the FD format information area in the system memory 2, and indicates the destination group registration area corresponding to it.

As shown in FIG. 12, the FD format information area in the system memory 2 and the destination group registration area corresponding thereto are set. And the same FD
Format type destinations are registered in the destination group registration area. In this case, the number of registered destinations does not necessarily have to be one, and a plurality thereof does not cause any problem. Also, when there are a plurality of format types that can be received by one communication terminal, the same registered destination is naturally registered in the destination group registration area corresponding to different FD format information areas.

FIG. 13 is a flow chart showing the flow of format check processing in the sixth embodiment of the present invention. In the figure, # 51 to # 53 indicate steps.

FIG. 13 shows the flow of FIG.
Only the process corresponding to step # 40 is shown. In step # 51, the contents of the non-standard function setting signal NSS (or signal TSI) sent from the transmitter side and the above-mentioned FIG.
Compare the contents of the destination group registration area shown in to check if there is a match. If there is a match, in step # 52, the n bits of the signal NSS are
It is investigated whether it is in the FD format information area of FIG. If it is in the FD format information area, reception is possible in step # 53.

As described above, in the sixth embodiment, in the case of routine work and the like, the signal TSI and the signal TSI described in the fifth embodiment are stored in the system memory 2 separately from the destination information. Information on a registered destination group having a BFT function for comparison with the signal RTI is registered. Then, at the time of transmission, the FD format type is determined by comparing with this information, as in the second and fifth embodiments. Therefore, the system memory 2 can be saved, and the same effects as those of the second and fifth embodiments can be obtained.
