Description

Detailed Description of the Invention

[0001]

The present invention relates to a facsimile machine,
In particular, the present invention relates to a facsimile device capable of transferring image data transmitted from a transmission source to a transfer destination designated by the transmission source.

[0002]

2. Description of the Related Art An ordinary facsimile apparatus reads image data of an original and transmits the image data to a destination facsimile apparatus or the like via a telephone line. When transmitting the image data, first, the telephone number of the transmission destination is dialed, and the data is transmitted according to a predetermined transmission control procedure. The transmission control procedure is the procedure to connect the source device and the destination device correctly, the procedure to confirm the other party, the data transmission, the confirmation whether the data is received correctly, and disconnect the line. It includes procedures for doing so.

Some facsimile machines have a function of transferring image data transmitted from a transmission source to a transfer destination designated by the transmission source. In such a facsimile apparatus, the non-standard function setting signal (NSS) and the sub address (SUB) are included in the procedure data transmitted and received in the pre-procedure before the data transmission among the above-mentioned transmission control procedures. In general, it is commonly used to transmit / receive transfer data of a transfer destination.

When transmitting the transfer data by using the sub address (SUB), the transmitting side notifies the receiving side that the sub address function is used by using the DCS signal. Specifically, by setting a specific bit of this DCS signal, the reception side is notified that the sub-address function is used. The SUB signal is a frame capable of transmitting 20-digit character information in ASCII code, and transmits the telephone number of the transfer destination to the receiving side. When the receiving side detects the flag with the sub-address function in the DCS, it regards the transfer data in the SUB as valid and stores it in the memory as the telephone number of the next transfer destination.

Further, the receiving side decodes the image data received by the data transmission procedure and outputs it on the recording paper. Further, it communicates with the transfer destination telephone number based on the transfer data, and transfers the received image data to the transfer destination device.

[0006]

In the above transmission control procedure, the image data transmission procedure is 9600b.
Although communication is performed at a high speed of ps to 14400 bps, the pre-procedure before transmission of image data is usually 300 bp.
Communication is performed at the communication speed of s. Therefore, if the subaddress transmitted / received in the pre-procedure includes the transfer data indicating the telephone number of the transfer destination, the communication time becomes long and the communication cost increases. Further, since the length of the sub-address is regulated, there is a problem that a plurality of pieces of transfer data cannot be transmitted and other data cannot be added to the transfer data and transmitted. Even if a plurality of transfer data can be transmitted, there is no standardized method for determining the transfer destination data to be transferred next from among them, so that the transfer from each relay station is not reliable. There's a problem.

It is an object of the present invention to receive transfer data of a transfer destination designated by a transmission source at high speed and also enable reception of additional information, and to specify a transfer destination to be transferred next from the transfer data. An object is to provide a facsimile device that extracts and realizes reliable transfer.

[0008]

A facsimile apparatus according to the present invention comprises a data receiving means, a decoding means, an output means, an encoding means, a transfer destination data extracting means, and a data transferring means. There is. The data receiving means receives the first code data transmitted from the transmission source. The decoding means decodes the first coded data to extract the image data and the transfer data which is one or a plurality of transfer destination telephone numbers. The output means outputs the image data. The encoding means re-encodes the image data to create second encoded data. The transfer destination data extracting means extracts transfer destination data to be transferred next based on the transfer data. The data transfer means transfers the first code data or the second code data via the line based on the transfer destination data.

Here, the transfer data, which is one or a plurality of transfer destination telephone numbers, is received as the integrated code data added to the image data, and the transfer data is compressed and encoded together with the image data. Therefore, it is possible to reduce the influence on the communication time. Further, a large amount of transfer data can be received, and the transfer destination data to be transferred next can be surely extracted by the transfer destination data extracting means, and reliable data transfer can be performed. it can.

Further, it is possible to have a structure further comprising own station number storage means for storing the own station number. In this case, the transfer destination data extracting means may be configured to extract the transfer destination data to be transferred next based on the transfer data and the own station number. Specifically, when one transfer destination data is encoded corresponding to one line of image data, the transfer data located in the line next to the transfer data corresponding to the own station number in this transfer data It can be extracted as transfer destination data to be transferred next.

Further, the encoding means can be configured to select the transfer data to be transferred to the next transfer destination from the transfer data, and create the second code data integrated with the image data. For example, the line of the transfer data corresponding to the own station number can be deleted from the transfer data included in the transmitted first code data, and the line can be combined with the image data. In this case, when transferring the code data, it is possible to reduce the communication time by omitting the data of the line corresponding to the own station number. Also, in the facsimile apparatus of the transfer destination which receives the code data, Processing becomes simple when performing decryption.

It is also possible to have a structure including the last line data which is located at the last line of the transfer data and indicates that the next transfer data does not exist. In this case, the final station that receives the transfer of the code data can easily determine that its own station is the final transfer destination. Further, the pre-procedure transmitting / receiving means is further provided, and the procedure data including the index of the transfer destination data to be transferred next is included in the procedure transmitted / received by the pre-procedure transmitting / receiving means. Based on this, the transfer destination data to be transferred next can be extracted from the transfer data. In this case, even a facsimile apparatus that does not have a storage unit for storing its own station number can easily extract the transfer destination data to be transferred next from a plurality of transfer data. The procedure data including this index can be included in the sub-address.

The operation of the above embodiment will be described. When the facsimile apparatus 1 is turned on, various parameters are initialized in step S1 shown in FIG. In step S2, it is determined whether or not an operation to perform the transmission operation has been performed. For example, when a document is placed on the document table 2 or there is a key operation for performing the transmission operation of the operation panel 3, the process proceeds to step S3 and the transmission process is executed.

In step S4, it is determined whether or not an incoming call is made from another facsimile machine or a fax modem via the line. When an incoming call is received from another device, the process proceeds to step S5 and the receiving process is performed. In step S6, other processing is performed, and then the process proceeds to step S2.
In the transmission process in step S3, the operation as shown in FIG. 4 is performed.

In step S11, it is determined whether or not the destination telephone number has been input. The telephone number of the transmission destination can be input by operating a ten-key pad included in the operation panel 3 or a registration key in which a number is registered in advance. If the telephone number of the transmission destination is not input, the process proceeds to step S12. In step S12, it is determined whether or not there is a cancel input. If it is determined that the cancel input has been made, this transmission process is terminated. If there is no cancel input, the process returns to step S11.

If it is determined in step S11 that the destination telephone number has been input, the process proceeds to step S13. In step S13, the input destination telephone number is temporarily stored in the RAM 14. In step S14, "Do you want to specify the transfer destination?" Is displayed on the liquid crystal display panel of the operation panel 3. Is displayed, and the operator waits for the input.

In step S15, it is determined whether or not there is an instruction input for designating the transfer destination. If the transfer destination is not designated, the process proceeds to step S16. In step S16, the original image is read by the image reading unit 11, encoded by an encoding method such as MH, MR, MMR, etc., and the process proceeds to step S25. In step S15, if there is an input to instruct the transfer destination, the process proceeds to step S17. In step S17, the liquid crystal display panel of the operation panel 3 displays "Please input the transfer destination number". In step S18, it is determined whether the telephone number of the transfer destination has been input. Also in this case, similarly to the case of inputting the number of the transmission destination, the input can be performed using the ten keys of the operation panel 3 or the registration key in which the number is registered in advance.

If no transfer data is input in step S18, the process proceeds to step S19. In step S19, it is determined whether or not there is a cancel input. If there is a cancel input, the process proceeds to step S16, and if there is no cancel input, the process proceeds to step S17. If the transfer destination number is input in step S18, the process proceeds to step S20. In step S20, the operation panel 3
On the LCD panel of, "Specify another transfer destination? Is displayed, and the operator waits for the input. If there is an instruction input to specify another transfer destination in step S20, the process proceeds to step S17. If no instruction is given to another transfer destination, the process proceeds to step S21. In step S21, transfer data is created based on the transfer destination telephone number input in step S18. For example, the destination facsimile number is "06-76.
4-1234 ”. In this case, as shown in FIG. 5, "9" indicating that the telephone number of the transfer destination has 9 digits is added to the beginning, and each digit has 4 bits of 2 digits.
Transfer data 21 is created by converting to a base number. As for the transfer data shown in FIG. 5, four transfer data 21 are created on the assumption that four telephone numbers are input in the transfer data input in step S18.

In step S22, the original image is read by the image reading unit 11 and binary two-dimensional data is created based on the grayscale information of the image. In step S23, transfer data is added to the beginning of the image data read in step S22 and combined. At this time, the transfer data 21 is stored in the transfer data area 22 (40 bits) of FIG. 5 so that one transfer data corresponds to one line of image data (1728 bits in A4 normal mode), and the remaining check is performed. The area 23 (1688 bits) is filled with "1". Also, in the line next to the last transfer data,
The final line data 24 filled with "1" is added. Therefore, the transfer data 26 including the transfer data for four lines and the final line data is added to the head of the image data 25.

In step S24, the data synthesized in step S23 is compressed by a two-dimensional coding method such as MR or MMR. In step S25, data transmission is started according to a predetermined transmission control procedure. When the data transmission is completed in step S25, the communication is completed in step S26. The transmission control procedure is performed as shown in FIG. Here, the binary transmission control procedure used for the G3 machine is shown. The left side in the figure is the transmission side and the right side is the reception side. First, a ringing tone (CNG) is transmitted from the transmitting side. The receiving side receiving the CNG signal transmits a called terminal identification signal (CED), a digital identification signal (DIS) and a non-standard function identification signal (NSF). When the transmitter receives the DIS signal, it transmits a digital command signal (DCS) which is a setting command in response to the DIS signal. Also, a non-standard function setting signal (NSS) that responds to the NSF signal and a sub-address signal (SUB) that originally stores transfer data are sent from the transmitting side to the receiving side.

Here, of the code data, the data of which the transfer data is added to the head is stored in the NSS signal,
The SUB signal remains empty and is transmitted or not transmitted. Next, the transmitting side transmits a training check (TCF) for confirming the training at the communication speed. For example, "1" is 1.5 at a communication speed of 14400 bps.
Send for seconds. The receiving side transmits a reception preparation confirmation signal (CFR) indicating that data transmission may be started when the TCF signal is normally received, and retransmits the training transmission when the reception of the TCF signal fails. Is transmitted as a training failure signal (FTT).

When the transmitting side receives the FTT signal, the communication speed is lowered by one rank and the TCF signal is transmitted again. Thereafter, this procedure is repeated until the transmission side receives the CFR signal, and if the CFR signal is not received even if the communication speed is reduced to a predetermined value, it is regarded that communication is impossible and the line is disconnected. When the transmitting side receives the CFR signal, code data including transfer data and image data is transmitted as an MSG signal at the communication speed at which the TCF signal was transmitted at that time. M
When the transmission of the SG signal is completed, a procedure end signal (EOP) indicating the end of one page and no continuous transmission is transmitted.

When the receiving side receives the EOP signal, it transmits a message confirmation signal (MCF) indicating that the code data is normally received. When the transmitting side receives the MCF signal, it transmits a disconnection command signal (DCN) to disconnect the line. In the transmission control procedure described above, 300 bps is used to prevent transmission errors other than DCF signals and MSG signals.
Communication speed is used.

The facsimile apparatus on the receiving side operates as shown in FIG. First, in step S31, it is determined whether or not the transmitted data includes transfer data. Here, the presence or absence of the transfer data in the code data and the addition position are determined by the data indicating the transfer data addition position included in the NSS signal. If it is determined that there is no transfer data, the process proceeds to step S32. In step S32, the code data is received from the transmitting facsimile machine. In step S33, the received coded data is decoded by the coding / decoding means 15 into image data. In step S34, the decrypted image data is visualized on the sheet by the image output unit 12 and output.

If it is determined in step S31 that the transfer data is included in the code data, the process proceeds to step S35. In step S35, the code data transmitted from the transmitting side facsimile device is received. In step S36, the received coded data is decoded by the coding / decoding means 15. In step S37, transfer destination data to be transferred next is extracted from the decrypted transfer data. Here, the own station number stored in the RAM 14 or the ROM 13 is compared with a plurality of decrypted transfer data, and if the own station number is found in the transfer data, the transfer data located on the next line is determined. Next, it is determined as the transfer destination data to be transferred. In step S38, the extracted transfer destination data is stored in a predetermined area in the RAM 14. In step S39, the line corresponding to the own station number in the transfer data is removed from the decrypted data, and the image output unit 12 visualizes and outputs the image on paper.

In step S40, the line corresponding to the own station number is removed from the plurality of transfer data received and decoded, and this line is recombined with the image data. In step S41, the image data and transfer data combined in step S40 are compressed and coded again by a coding method such as MR or MMR. In step S42, RA in step S38
Based on the transfer data stored in M14, the transfer destination telephone number is dialed to establish a line connection. Step S4
In step 3, the code data encoded in step S41 is transferred to the transfer destination, and if the transfer is completed, the communication is ended in step S44. The transmission control procedure of step S43 is the same as the procedure between the transmission source and the reception side (relay station) and is as shown in FIG.

In the above-described facsimile apparatus according to the present invention, the transfer data is compressed and encoded together with the image data, and since it is transmitted and received at high speed, the addition of the transfer data has an effect on the communication time. Is less. Further, each transfer data is added as data for one line of the image data, and a plurality of transfer data can be added. Further, it is possible to add data other than the transfer data, for example, the number of error lines generated can be used as the additional information. [Other Embodiments] (A) Transfer data can be added to the end of image data. In this case, the compression efficiency in the case of using a two-dimensional encoding processing method such as MR or MMR is increased, and the communication time can be further shortened. (B) When the received code data is decoded and then output on the paper, the transfer data corresponding to the own station number may be directly output without being removed. Similarly, when re-encoding and transferring, the transfer data corresponding to the own station number may be directly encoded and transferred without being removed, or the received code data may be transferred as it is as transfer data. . (C) When inputting the transfer destination number, the transfer number is previously stored in RAM
It may be configured to be stored in the storage unit 14 and displayed on the liquid crystal display panel of the operation panel 3 or the like for reference during communication involving transfer. (D) It is also possible to include the index of the transfer destination data to be transferred next in the sub address (SUB) for transmission and reception. In this case, for example, when data is transmitted from the first transmission source, the SUB signal is transmitted with the index of "2" included. The receiving side receiving this recognizes the data of the second line in the transfer data as the transfer destination data to be transferred next, and transmits the coded data re-encoded to the transfer destination.
In this case, since the own station number and the transfer data are not compared, the transfer data and the image data are recombined and re-encoded without deleting the transfer data corresponding to the own station number. Also, the sub address (SUB) at the time of transfer is the S at the time of reception.
The content of the UB signal is incremented and transmitted to the transfer destination.

In this case, it is possible to surely instruct the transfer destination data to be transferred next by the SUB signal, and it is also possible to deal with the facsimile apparatus in which the own station number is not registered. (E) The image output unit may be a thermal recording paper or a thermal transfer recording system.

[0035]

In the facsimile apparatus according to the present invention, since the transfer data is encoded together with the image data, the transfer data can be compressed similarly to the image data and can be transmitted / received at high speed. Therefore, even if a plurality of transfer data are added, the influence on the communication time is reduced. Further, the transfer destination data to be transferred next can be reliably extracted from the plurality of transfer data, and the data transfer can be surely performed. Further, a large amount of data can be added, and it is possible to add data other than the transfer data.
