Description

Description: TECHNICAL FIELD The present invention relates to a facsimile communication method in a facsimile system for transmitting image information to a plurality of destinations via a relay station based on a request from a transmission source.

[Conventional technology]

Conventionally, the relay broadcast function in facsimile communication is mainly used by large corporations for facsimile communication between heterogeneous networks (for example, G3 facsimile connected to a telephone line and G facsimile connected to a digital line) between different networks. It is used as important in in-house networks. In order to give a relay instruction to the relay broadcast facsimile, the facsimile communication procedure can be realized by its own mode (a procedure in which communication can be performed only between facsimile machines of the same manufacturer) or a relay instruction is made by a tone signal of a push phone. There is a method.

[Problems to be solved by the invention]

However, the above-mentioned conventional example has the following disadvantages when constructing a facsimile relay broadcast network.

(1) Even if an expensive relay broadcast facsimile is introduced, the relay cannot be performed unless the facsimile that issues the relay instruction is a product of the same manufacturer. Even products of the same manufacturer without a relay instruction function cannot be used. That is, the existing facsimile cannot be used for the relay broadcasting system.

(2) A relay instruction by the push phone can be used for a relay instruction from an analog line, but cannot be used on a digital line.

(3) In order to perform the operation by the relay instruction, the operator must perform an operation necessary for the relay separately from the normal transmission operation, which is troublesome.

(4) It is troublesome to check the contents of the relay instruction. The operator is always stressed when performing the relay instruction operation.

(5) Further, in order to solve the above-mentioned problems, it has been proposed to make a request for relay broadcasting using a mark sheet or the like. However, conventionally, in this case, image information input unconditionally is used. Is recognized as a destination instruction image. Therefore, when this recognition is not necessary, the processing therefor is useless.

Means for Solving the Problems In view of the above problems, the present invention relates to a facsimile communication method in a facsimile system for transmitting image information to a plurality of destinations via a relay station based on a request from a transmission source. Inputting image information including a plurality of destination designation images, determining the number of pages of the input image information, and inputting the image information if the number of pages of the image information is determined to be plural in the determination step. Analyzing the plurality of destinations based on the destination designation image, and transmitting the image information input in the inputting step to the plurality of analyzed destinations; and An object of the present invention is to provide a facsimile communication method characterized in that when the number is determined to be one page, the analysis in the analysis step is not performed.

This sheet is added to the document as the first page of the document to be relayed and transmitted to the relay facsimile station (first stage). The entry example shown in FIG. 3 is a request for a one-stage relay broadcast. As the relay broadcast destination, the contents of the "01" table registered in the relay facsimile and the G3 facsimile of the dial number 123-4567 are dialed. The instruction to execute the added relay broadcast of the G4 facsimile with the number 7654321 is shown.

An example of the entry in FIG. 3 will be described with reference to FIG. FIG. 1-C adds a completed OCR sheet shown in FIG. 3 to 1-B and transmits the document. 1-B analyzes the received first page and detects that it is an OCR sheet (FIG. 3-E).

The other resolution and image size are fixedly operated to the same as those of 200ppi and A4. However, the resolution and the encoding method are not limited to this.

11 to 22 are flowcharts showing the control operation of the control unit 2-A in FIG. 2 of the present system. Hereinafter, the operation of the apparatus will be described with reference to the flowcharts in FIG. 11 and subsequent figures.

When there is an incoming call to NCU2-N via an analog line,
2-H detects this and seizes the line. At the same time 2-H
Notifies 2-A that 2-A has received a call on the G3 line side. 2-A detects this (STP00 in FIG. 11) and

Proceed to 1.

When communicating via an analog line, 2-H transmits a digital identification signal (DiS signal) to the calling terminal. The unit has MH and MR codec capability, the paper size is A4, and the fine mode ( 200ppi resolution). Proceeding to S1 in FIG. 12, 2-A is 2-H
Wait for the receiving command of the partner machine to be notified (TSi / DCS
signal). If a receiving command is notified from 2-H (STP1
1). A new file is created in the file registration table shown in FIG. 6 (STP12). A new file is managed by finding an area in which the content indicated in the file registration table top address is empty (NULL) data and writing a file name, for example, RECREC01 ▼, therein. Next, a check is made as to whether the other device is registered in the device as a relay instruction station (STP13). For this reason, a pointing station registration table as shown in FIG. 4 is prepared in this machine, and the dial number of the partner terminal which is to be the relay pointing station of this machine is registered in this table. On the other hand, 2-A can know the other party identification number when notified of the reception command from 2-H (TS
i)), it is compared with the contents of the pointing station registration table in FIG. 4 to determine that the partner station is a relay pointing station.

If it cannot be identified as a relay instruction station, a blank (NULL) is entered at the top address of the service information area of the RECREC01 ▼ file in the file registration table in FIG. 6, the relay service is prohibited, and S11 (FIG. 14) STP110).

If the partner station is a relay instruction station, the address of the service information area is written in the service information area start address (6-D) (STP14) to create service information.

In the service information in FIG. 6, the relay instruction station type (in this case, 'G3'), the relay instruction station number, and the execution status are entered (STP15), and the flow shifts to S11 in FIG.

In S11, the address of the page information table is entered at the top address of the page information table of FIG. 6 ▼ REC01 ▼ file, and all the page information tables are cleared to NULL (STP110). In the page information table, the storage position and the encoding information in FIG. After the information of the first page to be received is entered (STP111), 2-H is instructed to transfer received image data to 2-K. The image information of the first page received by 2-H is transferred to the 2-K image memory, and then stored in the 2-Q hard disk (STP112, 113). If 2-H continues to receive the next page, return to STP111,
The second page is processed. Similarly, reception is continued up to the n-th page. When the reception processing of the last page has been completed in STP114, the next page information address in the information entry column of the last page of the page information table is cleared to NULL (this indicates that it is the last page. STP116).

At this time, if the number of received pages is 1, it is determined that the relay service using the OCR sheet has not been requested,
If the number of received pages is two or more, it is determined that there is a possibility that a relay service using an OCR sheet has been requested. Therefore, when the number of received pages is 1, the service information area start address of the file in FIG.
Prohibit the relay service (STP119) and proceed to S31. Even if the number of received pages is two or more, if the service information area start address of the ▼ REC01 ▼ file has been cleared to NULL, the process proceeds to S31 (STP118). Only when the number of received pages is 2 or more, and the start address of the service information area of the file REC01 ▼ file is not cleared to NULL,
Move to S12.

In S12, the received image data of the first page is 2-F
To perform OCR analysis. First, Hard Disk 2
Transfer the received first page from -Q to the image memory 2-K. At this time, the data is read from 2-Q by referring to 6-L of the page information table of the file REC01 ▼ of FIG. Next, the decoder 2-E is set to the parallel output mode to 2-F, and the decoding method is set to 2 by referring to the page information table.
Set to -E (in this case MR). Next, the image information of the first page received on 2-K is transferred to 2-E,
At the same time, it instructs 2-F to transfer an image. This allows 2-K
The image information transferred from to the 2-E is decoded by the 2-E using the MR method, converted into a 200 ppi pixel signal, and transferred to the 2-F. When decoding of one page is completed, 2-
F performs an OCR analysis on the transferred pixel signal. The result of 2-F executing OCR is 2-A as a character turn as shown in FIG.
(The example in FIG. 7 corresponds to the example of entry in the OCR sheet in FIG. 3.) For characters that cannot be recognized, “?” Is notified. The top character is
If the character is other than the sheet recognition character 'C', it is determined that the sheet is not an OCR sheet. Also, when a decoding error (decoding error) occurs during execution of decoding by the 2-E, it is not determined to be an OCR sheet. This is to prevent the OCR from erroneously recognizing due to a line omission due to a line error as shown in FIG. If it is determined that the sheet is not an OCR sheet as a result of the OCR execution, the ▼ RE
C01 ▼ NUL for the service information area start address of the file
Clear L to prohibit the relay service, and proceed to S31 in FIG.

If the received first page is determined to be an OCR sheet as a result of the above determination, the service information area 6-J, 6-Q, 6- in FIG. 6 is determined based on the recognition result in FIG. R, 6-S, 6
Complete and complete -T and 6-U, 6-V, 6-W. At the same time, the page information table top address is
Rewrite to the top address of the page information area of the page,
An operation is performed so that the received second page becomes the first received page on the table (the OCR sheet is not relayed). Here, it is assumed that the OCR recognition result of FIG. 7 has been obtained. In this case, 6-Q is 1, 6-R is NULL, 6-2 is
01, 6-V and 6-W have "123-456, G3" and "765432".
1, G4 ”is entered (STP128).

In addition, 6-H is changed from "OCR analysis" to "relay transmission wait".
(STP129) and shift to S4.

In S4, the file waiting for relay transmission is searched, and the primary relay,
The secondary relay is determined and executed.

First, in the file registration table in FIG. 6, the execution status (6-H) is added to the service information of the file.
Search for the file that says "Waiting for relay transmission". In this case, the file name ▼ REC01 ▼ is equivalent (STP4
1). Next, if the number of relay stages is 1 (primary relay), broadcast transmission is started, and if the number of relay stages is 2 (secondary relay), the process shifts to S5 in FIG. 20 to execute secondary relay. In the case of the primary relay, after the completion of the relay broadcast transmission, the execution completion file is cleared to NULL from the file registration table in FIG. In this case, all areas of the ▼ REC01 ▼ file are cleared to NULL.

In step S5 of FIG. 20, the secondary relay station performs relay transmission to the secondary relay station to perform secondary relay.

In STP50, the secondary relay station destination number (6-R) is given to 2-J, and a calling command is issued. 2-J receives this and calls,
Connect to secondary relay station. The STP 51 confirms this, passes the copied information of 6-S, 6-V, and 6-W to 2J, and transmits it to the secondary relay station as a control document (STP52). After the transmission of the control document is completed, the apparatus sequentially transmits the received images received from the relay instruction station to the partner apparatus. When transmission is completed, the process returns to the standby state.

On the other hand, when the process proceeds to S2 in FIG. 13 in the G4 communication by the digital line, the CDS (reception command) signal transmitted by the other party is determined, and it is determined whether the reception is the simple reception or the secondary relay instruction (STP2
0). In the case of the secondary relay instruction, the CDVI information received first is not an image signal but a control document in which control information necessary for performing secondary relay is incorporated. In the case of simple reception, the CDVI information received first is an image signal.

If the receiving command takes the form of simple reception in STP20,
A new file is created in the file registration table shown in FIG. 6 (STP22). Next, if the other station is not registered as a relay instruction station in this unit, relaying is not performed.
Proceed to 4 to clear the service information area start address to NULL, and then proceed to S20 in FIG. If the destination machine is registered as a relay instruction station, the process proceeds to STP25, where the address of the service information area is entered in the service information area start address (6-D) to create service information (STP2).
6). Then, the process proceeds to S21 in FIG.

STP20 when receiving instruction notifies secondary relay instruction S
Proceeding to TP27, the first received CDVI information (including the secondary relay station destination number, the relay destination table number and the relay destination station number as the secondary relay destination control information) is decoded, and the file registration table is decoded. Create a new file in
At this time, the service information indicates “1” for the number of relay stages (6-Q).
And the relay destination table number and the individually designated destination information are created by copying the contents of the received control document. This newly created file apparently takes the form of executing the operation of the primary relay. Then, the process proceeds to S11 in FIG.

In S20 of FIG. 16, the image data (CDUI) received in 2-J is transferred to the image memory 2-K by STP200 for one page. When the transfer of one page is completed by the STP201, the decoder 2-E is instructed on the MMR decoding method (STP202).
-2 is set to L level, 2-4 and 2-6 are connected, and the printer is activated (STP203). By transferring one page of the image on 2-K from 2-K to 2-E, the decoder 2-E outputs the decoded image signal to 2-4, and the printer starts printing (STP204). If the next page is received in 2-J, the flow returns to STP200 again to print out the second page. If the communication between the partner device and 2-J has been completed, the process returns to the standby state (STP206).

As described above, in S20, the received image on 2-K is not stored in the hard disk, but is printed out every time a page is received.

In step S21 of FIG. 17, the STP 210 writes the address of the page information table in the page information table start address of the newly created file, and prepares for management of the received page. Next, in the order of reception (firstly the first page), page information of the page to be received is created in the page information table.
Coding method MMR, hard disk storage start address (6
In (L), the head address of the file on the hard disk is created as the information of the first page (STP211).

Next, the image data received in 2-J is transferred to the image memory 2-K for one page. Next, the page transferred on 2-K is saved on the hard disk 2-Q. If 2-J has received the next page, the process proceeds to STP215, and if 2-J and the other device have finished communication, the process proceeds to STP214.

In STP215, the process waits until 2-J starts receiving the next page, and returns to STP211. In STP 211, page information of the second page is created. The encoding method is MMR, and the hard disk storage start address (6-L) is the address next to the first page storage end address. Thereafter, the sequence proceeds similarly to the processing of the first page.

When the process proceeds to the STP 214 on the last page, the area after the (n + 1) th page of the page information table is null-cleared (it is assumed that up to the nth page has been entered. At this time, the nth page is determined as the last page). ). Next, it is determined whether the received page is only one page or 23 or more pages (STP216). Do not relay if there is only one page (even if
Even if it is an OCR sheet, there is no page to be relayed), so shift to STP218, clear the service information area start address of the file registration table to NULL, and delete the service information. Then, the process proceeds to S31 in FIG. If it is determined in STP216 that two or more pages have been received, the service information start address in the file registration table is NULL,
It is determined whether or not it has been entered, and if it is NULL, it does not relay, so it proceeds to S31, and if it has been filled, it relays, so S12 in FIG. 15
Proceed to.

In step S31 in FIG. 18, the received page is pulled out from the hard disk 2-Q and printed. The STP 310 searches the page information table specified by the file registration table, and finds the n-th page (n = 1,
2,3…). Initially, n = 1. If the area of the n-th page has been cleared to null in ST311, it is considered that all pages have been output and the process returns to the standby state. Information on page n is NULL
If not, go to STP312.

In STP312, the corresponding page (nth page) is
Transfer to 2K. Next, the decoding method is set in the decoder 2-E with reference to the n-th page 6-M (STP313), and 2-2.
To L level and connect 2-4 and 2-6 to printer 2-
S is activated (STP314). Then, the n-th page transferred on 2-K is transferred from 2-K to 2-E (STP3
15). As a result, the n-th page starts to be printed out from the printer 2-S. After finishing the page transfer from 2-K to 2-E, n output from the page information table by STP316
Delete the page information of the page. The erasure is performed by rewriting the page information table start address of the file registration table to the page information start address of the (n + 1) th page of the page information table. Return to STP310 again.

When the output of all pages in the table is completed in this way, the process returns to the standby state.

FIG. 21 shows a control unit 2-A for executing the relay broadcast transmission.
FIG. 4 is a flowchart showing the control operation of FIG.

FIG. 22 is a flowchart when the contents of the page information table are transmitted to the partner machine.

First, the STP 430 of FIG. 21 refers to the relay destination registration table number (6-S) and obtains 5-F and 5-G from FIG. 5-C.
Read the contents of

At the next STP431, the contents of 6-V and 6-W and 5-F and 5-
From the contents of G, a broadcast destination list is created, and it is determined in STP432 whether transmission to all of the destinations has been completed or not. When the transmission ends for all destinations, the broadcast transmission ends. If not, go to STP433.

The STP433 determines whether the destination to be transmitted is G3 or G3, and proceeds to STP435 for G4 and to STP434 for G3.

In STP435, a destination number is given to 2-J, a calling command is issued, and a connection is made to the destination. In STP434, a destination number is given to 2-H, a call command is given, and connection is made with the destination.

In STP436, relay transmission is performed to the connected
Return to STP430.

Next, in the image transmission shown in FIG. 22, each received page is decoded into a pixel signal by a 2-E decoder with reference to the page information table, and the decoded pixel signal is matched with the partner device by the encoder 2-D. Encoding is performed to convert and transmit the image page. For example, the image page received by G3 is MR
(Or MH) coded, but when this is transmitted on G4, the MR (or MH) is coded, but when it is transmitted on G4, the MR (or M
The page H) is converted as an MMR image page corresponding to G4 using the above 2-E and 2-D.

First, the encoding method of the received page is set in the decoder 2-E with reference to the page information table. Next, 2-2 is set to H to connect the output 2-4 of the decoder to the input 2-3 of the encoder 2-D. In the encoder 2-D, the encoding method of the partner device to be transmitted is set. Hard Disk 2-Q
Then, the page is read in 2-K, and the page read in 2-K is transferred to 2-E. Thereby, 2-E decodes the page transferred from 2-K into a pixel signal, and outputs it to 2-D. 2-D encodes the pixel signal and transfers it to 2-K. A converted page is created in 2-K by the above series of processing (STP532). If this is G3, 2-H, G4
Then, the image is transmitted by transferring the images to 2-J, respectively. In this case, the data flow is as shown in FIG.

FIG. 24 is an external view of the apparatus of this embodiment. 25th
The figure shows the G4 facsimile communication procedure, and FIG. 26 shows the G3 facsimile communication procedure.

The G4 communication procedure in FIG. 25 is based on the G4 facsimile communication control unit 2-
This is executed by J, and the dial number (identifier) of the transmission source is identified by CSS. In RDCLP, for example, a resolution of 200 ppi and a size of A4 are declared.

The CDS notifies the control unit 2-A from 2-J as a reception command.

The G3 communication procedure shown in FIG. 26 is executed by the G3 facsimile communication control unit 2-H, and the dial number of the transmission source is identified by the TSI. In the DIS, for example, a resolution fine (equivalent to 200 ppi) and a size A4 are declared.

The DCS notifies the control unit 2-A from 2-H as a reception command.

In this embodiment, the facsimile apparatus which operates as a relay station has been described. However, a reader 2-T shown in FIG. 2 may be provided to function as a normal facsimile.

As described above, according to this embodiment, the OCR sheet is read,
All communicable facsimile machines (including G3 and G4 machines) can be used as relay instruction stations for relay broadcast facsimile machines.

Also, since the relay instruction is given by the OCR sheet, it is easy to confirm the content of the relay instruction.

In addition, since the relay instruction is performed by the OCR sheet, the same operation as the normal transmission operation can be performed, operability is improved, and malfunction is reduced.

In addition, since the relay is performed by communicating the OCR sheet in which the address is entered, the contents of the relay can be easily confirmed.

When a relay instruction is issued, a normal transmission operation may be used. Also, the OCR sheet can be used as many times as it is filled out. In addition, since the sheet is a handwritten sheet, it is easy to change or add a destination.

When relay transmission is desired, the operator only needs to add an OCR sheet to the cover of the document, and the operability and confirmation (visibility) are very good.

In this embodiment, since the OCR sheet having the decoding error is not recognized, the erroneous recognition of the OCR due to the influence of the analog line noise is rejected in advance, and the reliability of communication (does not result in an erroneous relay instruction) is improved. be able to.

In addition, according to the present embodiment, the relay station does not need the OCR
Since no sheet is transmitted, the communication cost can be reduced.

In this embodiment, when the number of received documents is one, it is possible to speed up the receiving process by determining that relay broadcasting is not performed.

Also, in this embodiment, only the registered terminal stations perform relay broadcasting. Therefore, when receiving from a terminal having no possibility of instructing the relay broadcasting in advance, the reception output becomes faster. As a result, the use efficiency of the memory at the relay station can be improved.
