Description

Description: TECHNICAL FIELD The present invention relates to a facsimile apparatus with a broadcast transmission function.

[Conventional technology]

When the same document is transmitted to a plurality of destinations, a facsimile apparatus reads and stores the document, and a device having a function of automatically transmitting sequentially to each designated destination is a general sequential broadcast facsimile device. It is. In the transmission method of the facsimile apparatus having such a function, even when the same destination is included in the image information stored in the facsimile apparatus, transmission to all destinations designated for one piece of image information is performed. Since the next image information is transmitted after the process, the image information is transmitted one after another in units of image information. Therefore, there is a problem that different image information of the same destination is transmitted separately, which is inefficient.

In view of such a drawback, a method of transmitting the image information of the same destination at one time has been proposed in Japanese Patent Application Laid-Open No. 62-157461, but in this method, one image information of one destination is transmitted to a certain destination. When the transmission processing is completed, it is detected whether or not there is the same destination in another image information, and if so, the processing of transmitting the image information is sequentially repeated. In this method, if all pieces of image information to be sent at a time are in the same mode (image width, sub-scanning line density, encoding method), the transmitting side sends MPS (MULTI PAGE SIGNAL) following image information of one page as shown in FIG. ) When a signal is transmitted and an MCF (MESSAGE CONFIMATION) signal is received from the receiving side, transmission is performed by repeating the procedure of transmitting the next page of image information, so that there is no problem. However, the transmitted manuscript has a choice of image width (A4, B4, A3 width) and sub-scanning line density (selection of image definition 3.85, 7.7, 15.4 / mm), and encoding method (normally binary images are MR codes). However, image information of different modes, such as the MH coding method is advantageous when reproducing halftones, is often used. In this case, the image information of different modes is shown in FIG. According to the mode change procedure, a mode change notification is sent from the transmission side to the reception side, and a process of transmitting the next image information (which takes about 13 seconds extra) is performed.

[Problems to be solved by the invention]

The above prior art does not consider that the efficiency is deteriorated by the mode change procedure.For example, the same destination is designated in the image information files No. 1, No. 2 and No. 3,
If the image information files No. 1 and No. 3 are in the same mode and the image information file No. 2 is in a different mode,
o.1 After transmission, go through the mode change procedure and
Since the transmission of No. 2 and the transmission of the image information file No. 3 after the mode change procedure again, there is a problem that the efficiency is not improved.

SUMMARY OF THE INVENTION An object of the present invention is to minimize the mode change when batch transmission to the same destination is performed, and to increase transmission efficiency.

Means for Solving the Problems The present invention provides a reading unit that reads image information, a compression unit that compresses the information, a transmission function that includes the compressed image information, a destination telephone number for each image information, and transmission parameters. , A memory unit for storing destination information comprising a transmission mode representing a transmission mode, an expansion unit for extracting and expanding the image information stored in the memory unit, and a transmission for transmitting the image information expanded by the expansion unit to a transmission destination. Unit, including a reception parameter of the transmission destination, comprising an identification unit for identifying a reception parameter representing a reception function, reading the image information by the reading unit, compressing the read image information by the compression unit And expands the stored image information once by the expansion unit at the time of broadcast transmission,
A facsimile machine with a broadcast transmission function for recompressing the decompressed image information in accordance with a receiving function of the other party in the compression unit and transmitting the compressed image information to the other party via the transmitting unit. At the time of transmitting the information, the same destination is selected from the memory unit storing the destination information including the destination telephone number and the transmission parameter for each of the image information and the transmission parameter of the destination information corresponding to the image information of the same destination. A transmission order that receives a transmission mode including the transmission mode and a reception parameter indicating a transmission destination reception function of the destination function identification unit and determines a transmission order so that image information can be collectively transmitted for each transmission mode having the same parameter. A determining unit is provided so that image information of the same destination can be transmitted at a time while controlling the transmission order of transmission image information.

[Action]

In batch transmission of the same destination in the broadcast transmission of the present invention, the same destination is selected at the time of transmission from the memory unit storing the destination information for each piece of image information, and the destination information of the image information corresponding to the same destination is taken out. After obtaining information identifying the receiving function of the other party, determining the transmission order of the transmission image information, and transmitting the information to the other party in a batch. By doing so, the mode change can be minimized.

〔Example〕

Hereinafter, an embodiment of the present invention will be described with reference to FIG. FIG. 1 is a block diagram of a facsimile apparatus showing one embodiment of the present invention.

The operator sets a document to be transmitted, sets a telephone number and a transmission mode to all transmission destinations from the operation display unit 6, and presses a start button. The control unit 1 activates the reading unit 2, the recording unit 3, and the compression / expansion unit 4, reads the transmission original, compresses the image information, attaches the file No. to the storage unit 5, accumulates the image information, and adds The transmission mode and the telephone number including the transmission parameters such as the accompanying image width and the sub-scanning line density binary / halftone are formed into a management table and stored in the memory unit 5.

The management table is stored in the memory unit 5 as shown in FIG. In the figure, the “number” indicates the total number of files for each file number, the “sent number” indicates the number of completed transmissions, and the “number” and “sent number” correspond to each other. It indicates that the transmission has been completed, and a non-matching portion indicates that an untransmitted page remains by subtracting the “transmitted number” from the “number”. Further, the transmission mode is stored in a code as shown in the figure to simplify the transmission order determination process. For example, the image width is 00 ... A4, 01 ... B
4,10 A3, sub-scan 00 3.85, 01 7.7, 10 15.4 / mm, binary / halftone 0 ... halftone 0 ... halftone (MH), 1 ... binary (M
R).

At the time of broadcast transmission, the control unit 1 reads out the management table of the memory unit 5, searches for the untransmitted destinations in ascending order of file No., extracts the telephone number, file No. remaining page and transmission mode, and further extracts Is searched for the same telephone number, and if so, the process of retrieving the file No., the remaining number and the transmission mode is sequentially repeated.
At this time, the control unit 1 transfers the file number and the transmission mode to the transmission order determining unit 9 in ascending order of the file number. The control unit 1 controls the modem NCU unit 7 based on the telephone number and calls the destination via the line 8. In response to a response signal from the partner facsimile, the partner function identification unit 10 detects reception parameters such as the recording paper width (image width), sub-scanning line density, and coding capability of the partner facsimile, and transfers information to the transmission order determination unit 9. The transmission order determination unit 9 compares the information from the partner function identification unit 10 with the transmission mode for each file number from the control unit 1, determines the transmission order of the file numbers, and transfers the information to the control unit 1. . The control unit 1 transmits the lowest number of the file No. first, and the subsequent transmission order is based on information from the transmission order determination unit 9. The comparison between the partner function information and the transmission mode and the determination of the transmission order are performed by the following method. The image width, sub-scanning line density and encoding capability of the partner function information are represented by the same codes as those in the file of the management table, and the calculation is performed by the method shown in FIG. Then, the result of the file with the lowest number is compared with the result of the other files, and the file with the matching file No. is sorted in the order of transmission. Is done. Here, file No.
If the transmission mode matches the youngest number, the calculation result naturally matches. This is because the transmission mode of the management table does not always match the transmission mode at the time of facsimile communication (for example, the transmission mode of the management table is 7.
Even if it is set at 7 / mm, if the partner function has only 3.85 / mm, it will be transmitted at 3.85 / mm. Therefore, by performing the calculation shown in FIG. , Are to be determined. When the control unit 1 transmits the last file in the order described above, the line is restored. Next, the control unit 1 searches for a destination that has not been transmitted, performs transmission in the same manner, and repeatedly executes until all files have been transmitted.

〔The invention's effect〕

Advantageous Effects of Invention According to the present invention, in the case where broadcast transmissions with different transmission modes are collectively transmitted to the same destination, the number of mode change procedures can be minimized, and the transmission efficiency is improved.

In the present embodiment, the case of general broadcast transmission has been described, but it is apparent that the present invention can also be applied to time-specified broadcast. The present invention can also be applied to special transmission modes such as a relay broadcast request and confidential transmission by expanding the transmission mode column in the management table.
