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]

Generally, the above-mentioned facsimile apparatus does not have a function of feeding back to the transmitting side whether or not the image data is normally received at the receiving side. . In particular, if you want the destination fax machine to transfer data to another device,
It is difficult for the sender to confirm whether or not the communication at each relay station has been performed normally. Therefore, the sender of the data may contact the telephone directly to confirm, or the confirmation of receipt may be returned at the transfer destination. It will be necessary to intervene with human resources such as receiving.
Therefore, there are problems that a new communication cost is required and the work becomes complicated.

An object of the present invention is to allow a receiving side device to transfer image data by designating a transfer destination from a source.
It is an object of the present invention to provide a facsimile apparatus capable of confirming whether or not data is normally received at each relay station.

[0008]

A facsimile apparatus according to the present invention comprises a data receiving means, a reporting means, a decoding means, an output means, an encoding means, and a data transfer means. The data receiving means is the first transmitted from the transmission source.
Receive coded data. The reporting means detects whether or not the data receiving means has successfully received the first coded data, and transmits a report of the reception state to a predetermined callback destination. The decoding means decodes the first code data to extract the image data and the transfer data which is the transfer destination telephone number.
The output means outputs the image data. The encoding means re-encodes the image data to create second encoded data. The data transfer means transfers the first code data or the second code data via the line based on the transfer data.

In this case, for example, by designating the transmission source that has started the transmission as a predetermined callback destination, the transmission source can receive a report from each relay station of the transfer destination that the code data has been normally received. Therefore, it is possible to easily confirm that the communication has been normally performed with each transfer destination. Here, the first
The configuration may further include pre-procedure receiving means for receiving the procedure data before receiving the code data. In this case, it is possible to send and receive the call-back number information corresponding to the predetermined call-back destination in the procedure data.

Further, the telephone number of the callback destination can be directly included in the procedure data as the callback number information, and the telephone number of the callback destination is indicated from a plurality of transfer data included in the transfer data. It is also possible to include it in the procedure data as an index of. This callback number information can be stored and transmitted in the frame of the subaddress in the procedure data.

Further, the encoding means can be constructed so as to integrally encode the transfer data and the image data to create the second encoded data.

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 a 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 S26. 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, number data is created based on the telephone number of the transfer destination input in step S18. For example, the destination facsimile number is "06-76.
4-1236 ”. In this case, as shown in the third line of the number data area 22 in FIG. 5, "9" indicating that the telephone number of the transfer destination is 9 digits is added to the beginning, and each digit is made up of 4 bits. The number data 21 is created by converting it into a binary number. The number data shown in FIG. 5 is assumed to be the case where three transfer destinations are specified in the transfer data input of step S18, and the telephone numbers of the transmission source and the first transmission destination are added to this, and the transmission source is added to the first line. Telephone number (A), second destination telephone number (B) on the second line,
Transferee telephone numbers (C), (D), on lines 3-5
Five number data 21 of (E) are created.

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, number data is added to the beginning of the image data read in step S22 and combined. At this time, the number data 21 is stored in the number data area 22 (40 bits) of FIG. 5 so that one number 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". Therefore, the number data line area 26 including the number data of five lines 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, callback number information is set. For example, the telephone numbers of the transmission source, the first transmission destination, and the transfer destination input in step S18 are displayed on the liquid crystal display panel of the operation panel 3, and the operator is instructed which number to call back. Let Usually, it is common to call back the facsimile machine of the transmission source, and in this case, the telephone number of the transmission source of the first line of the number data is set to be called back. In this case, the subaddress (SU
Set "1" to the frame of B).

In step S26, data transmission is started according to a predetermined transmission control procedure. When the data transmission is completed in step S26, the communication is completed in step S27. 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, the data indicating that the number data is added to the head of the code data is stored in the NSS signal, and the SUB
The signal is set to "1" and transmitted.

Next, a training check (TC) for confirming the training at the communication speed is actually made from the transmitting side.
Send F). For example, "1" is 14400 bps
It transmits at the communication speed of 1.5 seconds. On the receiving side, this T
When the CF signal is normally received, a reception preparation confirmation signal (CFR) indicating that data transmission may be started is transmitted, and when the reception of the TCF signal is unsuccessful, training transmission is requested again. Signal (FTT)
Send

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, the code data including the number data and the image data is transmitted as the 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 error except for TCF signal and MSG signal.
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 an incoming call is received from another facsimile device. When the call is received from another facsimile apparatus, the process proceeds to step S32. In step S32, the DCS signal, the NSS signal, and the SU sent from the sending facsimile machine
The procedure data such as the B signal is received, and then the code data is received. It is determined whether the reception in step S32 has been normally performed. When the reception is not normally performed, the process proceeds to step S45. In step S45,
Normally, the fact that there is an abnormality is displayed on the operation panel 3, and the process ends. When it is determined in step S33 that the data reception is normally completed, the process proceeds to step S34. In step S34, the received code data is encoded /
The decrypting means 15 decrypts the image data and the number data which is the telephone number of the transfer destination.

In step S35, transfer destination data to be transferred next is extracted from the decrypted number data.
Here, the own station number stored in the RAM 14 or the ROM 13 is compared with a plurality of decrypted number data, and if the own station number is found in the number data, the next number data located on the next line is searched. It is determined as the transfer destination data to be transferred to. In step S36, the extracted transfer destination data is stored in a predetermined area in the RAM 14. In step S37, the decoded image data is output to the image output unit 1
2 visualizes on paper and outputs.

In step S38, the received and decoded plural number data are recombined with the image data. In step S39, the image data and the number data combined in step S38 are compressed and encoded again by an encoding method such as MR or MMR. In step S40, step S3
Based on the transfer destination data stored in the RAM 14 in 6,
Dial the transfer destination telephone number to connect to the line. In step S41, the code data encoded in step S39 is transferred to the transfer destination, and when the transfer is completed, step S42
To end communication. The transmission control procedure of step S40 is the same as the procedure between the transmission source and the reception side (relay station) and is as shown in FIG.

In step S43, the callback number is extracted based on the content of the sub address (SUB) transmitted from the facsimile machine on the transmission side. For example, S
If the content of the UB signal is "1", the data of the first line in the number data is recognized as the telephone number of the callback destination, and this is taken into the RAM 14. As shown in FIG. 5, in the number data in which the telephone number of the transmission source is recorded on the first line, if the content of the SUB signal is "1", the number data of the transmission source is determined as the callback destination. Step S
In 44, based on the callback number determined in step S43, a report indicating that data has been normally received is transmitted. The data transmitted here may be configured to return the coded data that has been encoded again, or may simply return a signal indicating that the communication has been normally performed.

In the facsimile apparatus according to the present invention as described above, a plurality of number data is compressed and encoded together with the image data, and the data is transmitted and received at a high speed, so that the influence on the communication time is reduced. Further, each number data is added to the image data, and it becomes possible to add a plurality of number data. By storing the information as to which number of the plurality of number data is to be called back as an index in the SUB signal and transmitting the information, it is possible to confirm to the predetermined facsimile device that the communication has been normally performed at each relay station. You can call back to. Therefore, for example, the transmission source device can easily grasp the communication status. Other Embodiments (A) It is possible to add the number data to the end of the 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) A communication status data area is provided after the number data area 22 in FIG. 5, and when data is normally received, a message to that effect is displayed in the communication status data area in the line where the own station number exists. The data shown may be stored, this data may be added and encoded together with the image data, and the encoded data may be called back. (C) When inputting the transfer destination number, the transfer number is previously stored in the 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 directly include the call-back destination telephone number in the sub-address (SUB) for transmission / reception. In this case, it is necessary to send procedure data to the effect that the subaddress includes the telephone number of the callback destination in the NSS signal for transmission. (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 number data is encoded together with the image data, the number data can be compressed similarly to the image data, and high speed transmission / reception is possible. Therefore, even if a plurality of number data are added, the influence on the communication time is reduced. In addition, the callback number for making a callback can be reliably extracted, and the communication status can be reliably reported.
