Abstract

PURPOSE:To receive a desired original only by causing the facsimile equipment (FAX) on a transmitting side to accumulate file numbers after adding the numbers to every original data and the FAX on a receiving side to designate the file number of a required original. CONSTITUTION:At a transmitting-side FAX 1, an original is set to a scanner unit 20t and reading of the original is designated after a file number adding and accumulating mode is set from an ope-port unit 19t. The unit 20t writes the picture information including a file number into a RAM 12t. When receiving- side FAX 2-1 is called from the FAX 1 side and a telephone line is connected between them, a transmission controlling procedure is executed and the data of the FAX 1 are read out from the RAM 12t and transmitted to the FAX 2-1. When the file number of the original required on the FAX 2-1 side is written in a RAM 13r on the receiving side, the file number is transmitted to the FAX 1 and only required data are transmitted.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a facsimile (FAX) communication system, and more specifically, in a case where there are a plurality of stored and transmitted documents, the transmitting side FAX is connected to the receiving side FAX, The present invention relates to a communication method that makes it possible to select and transmit only requested buttock original image information.

[Prior Art] Conventionally, in normal storage transmission and polling transmission in FAX communication, all image information of a document stored on the sending side is transmitted.

In other words, once multiple documents are stored on the sending fax machine,
If only the image information of the required document is selected and transmitted from among them, all the accumulated image information will be transmitted to the calling destination or the polling destination.

[Problem to be solved by invention] By the way, between each automobile sales department and the head office, etc.
The head office compiles the monthly sales figures for each day.
By using a FAX with a circular communication function to send data to each department's facsimile, it is possible to understand the current sales trends and to boost the morale of each department to promote sales.

In this case, each DC already knows its own sales volume, and there is no need to receive notification from the head office regarding at least that data.

On the other hand, as mentioned above, with conventional FAX communication, it is not possible to select and send only a part of the accumulated document image information to each destination, so the entire document must be sent, which reduces the sending time. The problem was that it became longer and communication costs increased.

Therefore, the present invention allows only a part of the original stored in the original sending side FAX to be designated from the original receiving side FAX, and
It was created with the purpose of providing a FAX communication method that solves the above-mentioned problems by transmitting only the image information of the required manuscript that has been designated as AX.

[Means for solving the problem] In order to achieve the above object, in the present invention, FA
In the storage transmission of A FAX communication method is adopted in which the user specifies the file number of the required document among the requested documents, and the document transmitting FAX transmits only the accumulated data of the document corresponding to the specified file number.

In normal storage transmission, as a control signal in the transmission control procedure described above, the PI of the NSF (non-standard function identification signal) in the transmission control procedure is sent to the document receiving side FAX.
You will be asked to specify the file number using F (FAX information field).

In addition, in polling transmission, as a control signal in the above-mentioned transmission control procedure, the original receiving side FAX or NSC (non-standard function identification signal) or DT in the transmission control procedure
The file number is specified using PIF of C (digital transmission command signal).

[Operations] In the present invention, when the document sending side FAX stores a plurality of documents, data for each document (image information for one page) is stored in association with a file number. Here, the file number serves as a search number when reading and transmitting data of each manuscript.

In this way, by attaching a file number to each document data stored in the FAX on the document sending side, it becomes possible for the document receiving side to specify the document to be received using the file number. In other words, if the document sending side and the document receiving side confirm in advance the correspondence between each document stored at the sending side FAX and the file number, the file number can be specified by the control signal of the transmission control procedure sent by the receiving side FAX. By doing so, it is possible to request the receiving side FAX or the sending side FAX to send only the required original.

As a control signal in this transmission control procedure, NSF can be used in normal storage transmission, and NSC or DTC can be used in baud link transmission. All of these are sent from the FAX on the document receiving side, and it is possible to allocate bits of the file number to the PIF of the frame structure.

The original sending fax machine that receives these control signals detects the file number by analyzing the PIF of the signal, searches for and reads only the document data corresponding to that file number, and sends it to the receiving fax machine. do.

[Embodiment] The FAX communication system of the present invention will be explained below with reference to FIGS. 1 to 6.

This embodiment will be explained by taking as an example the FAX communication between the above-mentioned head office and each sales dealer.

FIG. 1 shows a FAX system circuit diagram on the head office side and the dealer side, and a schematic diagram of the communication network. Here, 1 is the head office side FA
X, 2-1 to m indicate the dealer side FAX, 3 indicates the telephone network, the head office side FAXI becomes the document sending side FAX, and the dealer side FAX
AX2-1 to AX2-m become the document receiving side FAX, and a document summarizing the monthly sales numbers of automobiles for each dealer is sent from the head office side to the dealer side by successive report transmission.

The head office side FAXI and each dealer side FAX 2-1 to 2-m have the same system, 11 is a ROM that stores the system control program, and 12 is a RAM that stores image information.

In the above configuration, the document storage procedure in the head office FAX 1 will be described first with reference to the flowchart shown in FIG.

After setting multiple originals [total (n+1) sheets including the cover] with sales numbers summarized for each dealer in the scanner unit 20t, and setting the storage mode with file number from the operation port unit 19t, start reading the originals. Instruct [Steps (1) to (3) 1. As a result, the scanner unit 20t starts reading the document, or this mote first stores the file number O in the RAM l.
2 written to t, and E is written to the address corresponding to that number.
At the same time as OL (line termination code) is written, the read image information of the first page (cover) is accumulated, and RTC (control return code) is written next to the last line of the image information, and the first page Reading is completed [Steps (4) to (August).

The procedure after starting this reading is to
) page [Steps (9) → (11)]
, the mode is canceled and the storage procedure ends when all the originals are stored in the RAM 12t [Step (9) D
o)]. The data processing related to reading and storing image information is the same as normal operation, and after storing the image information transferred from the scanner unit 20t in the line buffer 14t, it is encoded and compressed by the DCR 15t for each line. is stored in RAM 12t.

As a result of the above, the RAM 12t has the format shown in Figure 3, that is, the file number and EOL for each page.
・Page data (image information) ・With RTC as unit frame data, the manuscript data of the first page (cover) and the second page to the (n+1)th page are stored.

Next, a signal sequence for transmitting the document data accumulated above from the head office FAX 1 to the dealer FAX 2-1 will be explained with reference to FIG.

First, the head office makes a call to the dealer, and when the telephone line is connected, the dealer's FAX 2-1 sends the called station identification signal (
CED: 2100 Hz)-null) is returned to execute the transmission control procedure, but NSF is sent after CHD. This NSF identifies specific user requests outside the scope of the CCITT Recommendation T series, and has a PIF of at least 2 octets.
No. 1 inserts the file number of the manuscript required by the dealer into this PIF bit and sends it to the head office FAXI.

The file numbers of the manuscript required on the dealer side are from page 1 to page 1 of the manuscript sent by the head office, and
This corresponds to pages i+3) to (H+l)th page. In other words, every month, the head office sends (n+1) pages of standard manuscripts including the cover page to each dealer, or at the time of sending, it sends them by FAX 2-1.
It is decided that the manuscript regarding the sales volume of the dealer where the company is located will always be sent on the (i+1)th page and the (1+2)th page, and this fact is confirmed in advance by the head office and the dealer.

Therefore, since the dealer already knows his own sales volume, the (i+1)th page and the (ith)
+2) Pages are no longer needed and we do not request to receive them, only other pages.

In addition, the writing of the file number to the FIF of NSF on the dealer side FAX 2-1 is done in the RAM 1 of the same FAX 2-1.
It is possible to write the necessary file number in 3r in advance as management data, and then execute it by writing it to the FIF at the stage of sending out the NSF.

In this way, after the dealer's FAX 2-1 sends the NSF, the same FAX 2-1 or C
After sending SI (Called Terminal Identification Signal) and DIS (Digital Identification Signal), head office side FAXI or NSS (non-standard function setting signal), TSI (Transmitting Terminal Identification Signal), DC
3 (digital command signal) and TCF (training check), and the dealer's FAX 2-1 returns a CFR (receiving readiness confirmation signal), and the head office's FAXI
will move on to transmitting image information.

From then on, the head office FAXI sends the image information (PIX') of the original stored in the RAM 12t to the dealer FAX 2-1 while exchanging MPS (multi-page signal) and MCF (message confirmation signal), starting from the first page. However, only the data of the manuscript specified by the above-mentioned NSF FIF will be sent, and when the first page is sent, the (i+1)th and (i+2)th pages will be sent. Ignoring this, the process immediately shifts to the transmission of the (i+3)th page, and then sequentially transmits the final manuscript, the (n+1)th page.

The control procedure of the head office side FAX 1 during this time is clarified in the flowchart of FIG. That is, when the reception of NSF is detected, the PIF is analyzed and file number data [0 to i.

(i+3) to (n+1) are detected and RAM 1st
[Steps (21) to (23)
)]. Next, when the reception of CFR is detected, the file numbers in the RAM 12t are sequentially searched based on the file number data, and the document data whose file numbers are other than [(i+1) and (i+2) are read out and sequentially retrieved. Send the manuscript data [Steps (24) to (29)]. Then, by transmitting up to the final (n+1)th page,
Documents or FAX 2-1 regarding the sales volume of other dealers
[Steps (29), (31)
,(30)■. Note that the data processing related to the transmission of image information is the same as the normal storage and transmission operation, and the compressed data is read from the RAM 12t, and the -MODEM data is read from the CCU 16t.
17t - sent to the line via NCU 18t, while the dealer side FAX 2-1 is sent to NCU 18t.
The image information received from r is sent to MODEM 17 r-CCU.
16 r to RAM 12r, and this RAM
12r as a receiving buffer, the image information is reproduced by the DCR 15r, further transferred to the line buffer 14r, and finally the image information is printed out by the plotter unit 21r. As a result, the dealer's FAX 2-1 contains pages (i+1) and (i+2) that are unnecessary for the dealer.
Pages of original documents are not printed out, thereby reducing communication time and communication costs.

By the way, by sequential report transmission, the original data is sent from the head office FAX 1 to the other dealer FAXs 2-2 to 2-m, but the signal sequence and processing procedure for the following two are the same; however, each RAM of dealer side FAX 2-2~m
Since the file numbers stored in FAX 13r are different, the head office FAX 1 will not transmit the manuscript data of the page corresponding to the missing file number.

Although the above has been described in the case of normal storage transmission, the present invention can also be applied to the case of polling transmission.

In this case, the head office FAX 1 adds a file number to each page of the transmitted manuscript and stores the manuscript data in the RAM 12t. However, since the signal sequence in the transmission control procedure specific to polling transmission is executed,
The control signals for specifying the file number are different from the dealer side FAX 2-1 to 2-m.

That is, in polling transmission, the dealer's FAX 2
-1 to m become the calling station, and after the prescribed transmission control procedure is executed, when the head office FAXI or CFR is sent, the dealer side FAX 2-1 to m delegate the right to send the message to the head office FAXI. Send DTC and NSC for

Therefore, in this embodiment, the PIF of this DTC or NSC is

~Send to m.

In the above embodiment, the file number is added to the beginning of the image information of each page in the transmission data in the RAM 12t, as shown in FIG.
If this is ignored by the DCR 15r of -1 to m, the image information will not be affected.

[Effects of the Invention] Since the present invention has the above configuration, it has the following effects.

In the invention of claim (1), the document sending side and the document receiving side confirm the file number for each transmitted document data in advance, and the document sending side FAX adds a file number to the document data and stores the document data. By specifying the file number of the required document with the control number on the receiving side FAX or transmission control procedure,
By making it possible to receive only the required manuscript, communication time is shortened and transmission costs are reduced, and in particular,
When the sending side periodically sends standard manuscripts, this happens when the receiving side instructs the receiving side not to send a manuscript whose contents are already known.

The invention of claim (2) makes it possible to specify a file number using NSF, and performs normal storage and transmission. The above effect can be achieved by sending a volink.
