Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information transmission device such as a facsimile device for transmitting facsimile information.

[0002]

2. Description of the Related Art Conventionally, for example, transmission of facsimile information between facsimile devices is generally performed in a standard mode (G1 to G4 mode) communication protocol determined in accordance with a recommendation of CCITT (International Telegraph and Telephone Consultative Committee). It was carried out based on.

For example, when a facsimile machine owned by oneself is used as a calling station and a facsimile machine of a destination desiring to receive is dialed by calling its telephone number as a called station, first, the facsimile machine of the destination is called. G
The performance is disclosed that the facsimile information can be transmitted in the standard mode from 1 to G4. Upon receiving the performance disclosure, if the facsimile machine as the calling station makes a selective setting to use any one of them, for example, the communication protocol in the G4 mode, the transmission speed or the like defined in the G4 mode is set. Facsimile information will be transmitted.

By the way, in a facsimile machine equipped only with such a standard mode, its performance (transmission speed, etc.)
Since it is not possible to increase the transmission speed or add a unique function, it is a non-standard that can increase the transmission speed other than this standard mode or add a unique function. Some have modes.

[0005]

However, such a non-standard mode allows manufacturers to freely set their own functions in accordance with CCITT's recommendations. Since the formats of functions and their function settings are different, information transmission using the non-standard mode could be performed only between facsimile machines of the same manufacturer equipped with the same non-standard mode.

[0006] For example, in information transmission between facsimile machines of different manufacturers, the facsimile machine as a calling station cannot know what kind of function the facsimile machine as a called station has in a non-standard mode. Therefore, the information transmission in the non-standard mode cannot be performed, and only the standard mode inferior in transmission speed and the like can be performed.

The present invention has been made in view of the above circumstances, and is a non-standard of information transmission between information transmission devices as a plurality of called stations, each of which has a different function. It is an object of the present invention to provide an information transmission device as a calling station which is made to perform by using modes.

[0008]

In order to achieve the above-mentioned object, the present invention provides an information transmission apparatus as a plurality of called stations equipped with non-standard modes having different functions as communication protocols in addition to the standard mode. In the information transmission device as the calling station that performs information transmission between the two, transmission for information transmission using the communication protocol in the non-standard mode provided in each of the information transmission devices as the called stations It is equipped with means.

Specifically, the transmission means includes a storage unit that stores data for specifying different non-standard mode functions respectively provided in the information transmission devices as a plurality of called stations, and the storage unit. It includes an emulation calculation unit for specifying a function of the non-standard mode equipped in the information transmission device as the called station based on the data of the unit and instructing communication line setting according to the function.

Then, for example, the storage unit is a card-shaped external storage medium containing a memory formed of an integrated circuit, and the called station and the calling station are configured as a facsimile device for transmitting facsimile information. It was done.

[0011]

According to this structure, it is possible to perform information transmission by using the non-standard mode having different functions provided in each of the information transmission devices as a plurality of called stations. Even when the manufacturers of the facsimile machines as the calling stations are different from each other, the facsimile information can be transmitted using the non-standard mode on the called station side.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A facsimile apparatus as an embodiment of the present invention will be described below with reference to the drawings. In the present embodiment, when the manufacturers of the facsimile machine as the called station and the calling station are different from each other, the facsimile machine on the calling station side emulates the non-standard mode equipped on the called station side, as if the called station was called. Information transmission using the non-standard mode function of the called station is performed as if the facsimile machine of the same manufacturer equipped with the same non-standard mode as the facsimile machine of the station side. It was done.

Here, the maximum number of NSF signals representing non-standard functions sent from the facsimile apparatus on the called station side is 25.
6 bits long, CCITT up to the first 32 bits
The stipulations in the recommendation have been set, and it has been decided that each manufacturer can set the remaining bits in a unique function in a unique format. Focusing on the fact that there is a maker code assigned to each maker as one of the designation items, the facsimile machines on the calling station side are different from each other and are installed in the facsimile machines as a plurality of called stations. Data for identifying each function in the non-standard mode is stored in advance, and data corresponding to the manufacturer code is extracted from the data and used for emulation.

FIG. 1 shows an example of a concrete block configuration of the facsimile machine, 1 is a network control unit (NCU) for controlling connection with a public data line such as a telephone line, and 2 is a signal sent to the line. A modulator / demodulator 3 which modulates for transmission and demodulates a signal transmitted from the line, 3 a scanner unit (ISU) for optically reading a document to be transmitted and converting it into an electric signal, and 4 for controlling the entire facsimile apparatus. A control unit (hereinafter referred to as “CPU”) 5 is a ROM in which a control program of the CPU 4 and the like are stored.

Reference numeral 6 is an emulation ROM in which data for specifying a non-standard mode function of the called station side facsimile apparatus, which is different for each manufacturer, is stored as table data for each manufacturer, and 7 is a specific use. The table data corresponding to the manufacturer code included in the NSF signal indicating the non-standard function sent from the facsimile apparatus on the called station side for identifying the request of the user is stored in the ROM.
6 is an emulation operation unit that specifies the function and sets the communication line based on the function. The emulation operation unit 7 stores in the RAM 8 having a memory capacity corresponding to at least the table data from among the specified functions. Set the bit part as an index that sets the function you want to use (in this case, change from 0 to 1)
After the function setting, the communication line is set by sending them to the called station side as NSS signals for non-standard function setting corresponding to digital commands for NSF signals. Here, since the RAM 8 is also used for temporarily storing the facsimile information from the called station in this case, its capacity is set to be larger than 256 bits. A printer unit 9 prints out the facsimile information sent from the calling station when it operates as a called station.

Therefore, when a facsimile machine having a block structure as shown in FIG. 1 is used as a calling station to transmit facsimile information, first, as shown in FIG. Make a telephone call (TEL) as a call station. Then, the facsimile machine on the called side of the other party makes a disclosure of its own performance. For example, when the called station is equipped with a non-standard mode communication protocol in addition to the standard mode, the called station sends out a DIS signal as a digital identification signal for disclosing the standard capability of the called terminal. Before it is done, an NSF signal representing a non-standard function will be sent. The CSI signal is a signal for identifying the called terminal which represents the international telephone number of the called terminal.

In response to this, the calling station side determines the manufacturer of the called station from the manufacturer code included in the NSF signal, expands the corresponding table data in the ROM 6 and specifies the function of the non-standard mode. Then, select the function you want to use from among the functions that can be used (depending on the model)
It is set in the AM8 and sent to the called station side as an NSS signal of non-standard function setting. For example, as shown schematically in FIG.
When the F signal is transmitted, the calling station receives the N signal and receives the N signal.
From the manufacturer code included in the SF signal, A in the ROM 6
When the company table data is expanded and its function is specified (for example, when it is known that the 39th bit is relay polling and can be used), if the 39th bit relay polling function is to be used, the corresponding RAM 8 is stored. By setting the 39th bit of and sending it as an NSS signal,
The relay polling function on the called station side works.

As a result, when the communication line is set up in the non-standard mode on the called station side, the calling station side sends out a TCF signal as a training check for confirming channel use at this data rate. When it is confirmed to be normal, a CFR signal for confirmation of reception preparation, which is a digital response for confirmation of message transmission start, is transmitted from the called station side, and in response thereto, image data is transmitted from the calling station side. Will come.

Then, the transmission of this image data is completed,
When the EOP signal indicating the end of the complete page of the facsimile information is sent from the calling station side, the EOP signal indicating the end of the procedure is transmitted, and in response to this, a message confirmation message indicating that the complete message has been satisfactorily received from the called station side. MCF signal is sent. In response to this MCF signal, the calling station side sends a DCN signal, which is a disconnection command indicating the start of call disconnection that does not require a response, and disconnects the line to complete the information transmission. If the calling station does not store the non-standard mode data of the called station, the DIS indicating the next standard capability is heard by listening to the NSF signal indicating the non-standard function from the called station. When the calling station receives the signal and sends out the DCS signal which is a digital setting command for the DIS, the communication line is set in the standard mode.

Although the present embodiment has described the case where the transmission is performed in the non-standard mode, when the called station is equipped only with the standard mode, the telephone call from the calling station is not received. Only the DIS signal indicating the standard capability and the CSI signal indicating the telephone number are transmitted from the calling station, and the information is transmitted in the standard mode. Further, in the present embodiment, reduction of software load on the CPU 4 portion,
In order to make it easier to add the emulation function to the existing facsimile machine, the emulation operation unit 7 is provided separately from the CPU 4, but C
You may make it shared by PU4. In addition, the data required for emulation is stored in the storage medium R
Although it is stored in the OM6, a card-shaped external storage medium having a built-in memory formed by an integrated circuit instead of a built-in one, a so-called IC card, may be used. It is possible to change the data according to the purpose such as a card, to change the data, and to easily expand the data.

[0021]

As described above, according to the present invention, for example, even if the manufacturers of the facsimile machines as the called station and the calling station are different, the facsimile machine on the calling station side is equipped with the called station side. Since the non-standard mode of the called station can be emulated and information can be transmitted in the non-standard mode of the called station, the performance of the called station can always be fully utilized.
