Description

Description: TECHNICAL FIELD The present invention relates to a sequential broadcasting device.

[Prior Art] In recent years, it has a large-capacity image memory and transmits the same image information to a plurality of facsimile stations, or stores a plurality of image information and designates it as a destination station set corresponding to each. Sequential broadcasting devices having the function of transmitting at specified times are in practical use.

In such a sequential broadcasting device, image information is stored in an image memory by distinguishing between an immediate transmission file that starts transmission immediately after storage and a time-specified transmission file that is transmitted at a specified time. is doing.

However, in the past, since the destination was called for each transmission file, the following inconvenience occurred.

For example, when storing the immediate transmission file, when the specified transmission time of the time-specified transmission file stored in advance has passed, and when the destinations of this immediate transmission file and the time-specified transmission file are the same, After the transmission of the time-specified transmission file is completed and the transmission line (for example, telephone line) is once disconnected, the transmission control procedure is started again for the same destination to send the immediate transmission file. The use efficiency of the broadcasting device is poor.

Further, even when a plurality of immediate transmission files are stored in the image memory and the destinations of these immediate transmission files are the same, the use efficiency of the transmission line and the sequential broadcasting device is poor for the same reason as described above.

[Purpose] It is an object of the present invention to solve the above-mentioned inconvenience and to provide a sequential broadcasting device that can improve the usage efficiency by continuously transmitting a transmission file of the same destination.

1f is a network control circuit for controlling a transmission line network such as a telephone line network to establish and disconnect the transmission line, and 1h is the scanner described above.
1a, a printer 1b, a buffer 1c, a code compression / expansion circuit 1d, a modem 1e, a network control circuit 1f, and a management information addition circuit 1g, each of which controls a CPU (Central Processing Unit), and 1i stores a program executed by the CPU 1h (ROM ( A read only memory), 1j is a RAM (random access memory) that forms a work area of COU 1h, and 1k is an external memory interface circuit that exchanges data between the facsimile section 1 and the storage / broadcast section 2.

In addition, the buffer 1c, the network control circuit 1f, the management information addition circuit 1
g, CPU1h, ROM1i, RAM1j and external memory interface circuit 1k are connected to the system line SB.

In the storage / broadcast unit 2, 2a is a facsimile interface circuit that is connected to the above-mentioned external memory interface circuit 1k to exchange data between the facsimile unit 1 and the storage / broadcast unit 2, and 2b suppresses the capacity of the image memory 2c. To achieve this, the code compression / expansion circuit and 2d are code compression / expansion circuits that code-compress the image data applied via the facsimile interface circuit 2a and restore the original image data by decoding / expanding the data stored in the image memory 2c.

2e is a CPU that controls the facsimile interface circuit 2a, the code compression / expansion circuit 2b, the image memory 2c, and the clock circuit 2d, and 2f stores a program executed by the CPU 2e.
ROM and 2g form a work area for CPU2e and RAM for storing management information (including sender information) and 2h
Is an input unit including a numeric keypad and function keys.

Further, the facsimile interface circuit 2a, the code compression / expansion circuit 2b, the image memory 2c, the clock circuit 2d, the CPU 2e, the ROM 2
The f, RAM 2g and input unit 2h are connected to the internal bus line IB.

FIG. 2 shows in detail the above-mentioned operation input section 2h. In the figure, OP is an operation panel, K1 is an automatic transmission key, K2 is a time designation transmission key, K3 is a polling transmission key,
K4 is a copy key, K5 is an immediate transmission key, 10K is a numeric keypad for inputting a numeral and time, SK is a start key and CK is a stop / clear key. The contact outputs of these keys are judged by the CPUs 2e and 1h to set the mode. Although other operation keys and various indicators are provided on the operation panel OP, the description thereof is omitted because it is not directly related to the present invention.

FIG. 3 shows a file management table for setting the transmission mode of the image information file when the image data of the transmission original is stored in the image memory 2c to form the image information file. This file management table FMT is set in the RAM 2g by the number of image files stored in the image memory 2c.

The file management table FMT is a management flag M that indicates which transmission mode the image information file is in.
F, file number NF indicating the order in which the image information file was stored, destination information TN that is a code such as the telephone number of the destination, and transmission time [hour / minute] information TT that indicates the designated transmission time at the time designated transmission. , A document count information PP that shows the total number of pages of the transmitted document, a page counter that shows the amount of transmitted information as the number of pages of the transmitted document, and a call that stores the number of re-transmissions when the PC and the destination station are communicating It consists of a frequency counter CT.

FIG. 4 shows details of the management flag MF. As shown in the figure, the management flag MF is a time designated transmission flag FTT, a batch transmission flag FBT and an immediate transmission flag FIT, which respectively indicate that the image information file is designated as one of time designated transmission, batch transmission and immediate transmission. An image information file managed by the file management table FMT includes a transmission request flag FRT indicating that the image information file has not been transmitted yet and should be transmitted.

Therefore, the operator sets the transmission original and presses the key K2.
When is pressed, the specified time is sent, so when forming the image information file corresponding to this sent document in the image memory 2c, the CPU 2e specifies the time of the management flag MF of the file management table FMT that manages this image file. The signal flag FTT and the transmission request flag FRT are set, the batch transmission flag FBT and the immediate transmission flag FIT are reset, the number of transmitted documents is counted, and the result is set in the document number information PP. Furthermore, the telephone number of the destination and the designated transmission time entered by the operator using the numeric keypad 10K are the destination information TN.
And transmission time information TT, respectively.

If the operator presses the key K1 during document storage, the batch transmission flag FBT of the management flag MF is set, and if the operator presses the key K5, the immediate transmission flag FIT is set. In this case, the designated transmission time is not input. Further, the transmission request flag FRT and the document number information PP are also set, as in the case of the time designated transmission file described above.

During such document storage, the CPU 2e determines how many times this document storage operation corresponds to on the day, and the result is stored in the file number NF. Therefore, files stored at earlier times have smaller file number NF values, and if file searches (table searches) are performed in the order of file number NF, transmission files can be transmitted in the order of storage.

As described above, various information related to each image information file is stored in the corresponding file management table FM when documents are stored.
Memorized in T.

FIG. 5 shows a transmission control flow in the broadcasting device MFX sequentially. This transmission control flow is a part of a main control flow for sequentially controlling the entire broadcasting device MFX. Moreover, since the main control flow is cyclically executed, the transmission control flow is repeatedly executed at extremely short time intervals.

As shown in the figure, in the transmission control flow, first, the routine FLIM for searching and transmitting the immediate transmission file is executed, then the routine FLBK for searching and transmitting the batch transmission file is executed, and finally the time designated transmission file is searched. Execute the routine FLST to send by sending.

FIG. 6 shows a routine FL for searching and transmitting a file for immediate transmission.
An example of IM is shown. In this example, after transmitting an immediate transmission file, all valid transmission files having the same destination as this file are transmitted in succession.

That is, a table search is performed using the file number FN of each file management table FMT as an index (process 11),
If there is a transmission file (the result of determination 12 is YES), it is determined whether or not there is a transmission request for this transmission file depending on whether or not the flag FRT of the management flag MF in the file management table FMT of the transmission file is set. (Judgment 13), and it is further judged whether or not it is the immediate transmission mode depending on whether or not the flag FIT of the management flag MF is set (Judgment 14).

If the result of determination 14 is YES, the destination information TN of the file management table FMT is transferred to the network control circuit 1f to call the destination station (process 15), and after the transmission line is established, the transmission file is handled. Image information is transmitted to the destination station (Process 1
6).

Then, after the processing 16 is completed, the table search is performed again before the transmission line is opened (disconnected) (processing 1
7), it is checked whether or not there is a transmission file with the same destination (decision 18). If such a transmission file exists, if the transmission file searched for has a transmission request (determination)
If the result of 19 is YES), it is further determined whether or not it is the time designated transmission mode (decision 20). If it is not the time designated transmission mode, it is the immediate transmission mode or the batch transmission mode, and the process returns to step 16 to transmit the transmission file.

Also, if the time designated transmission mode is determined in Judgment 20, if the transmission designated time is exceeded (the result of Judgment 21 is
(YES) only, the process returns to the process 16 to transmit the transmission file, and if not, the process returns to the process 17 and repeats the table search.

The above operation is performed for all the file management tables FMT, and the image information in which the same destination is set is continuously transmitted.

Routine FLBK and routine FL that follow this routine FLIM
In ST as well, similar to routine FLIM, if the transmission files to which the same destination is set are to be transmitted successively, the procedure is as follows.

That is, the routine FLBK is the “decision 14” of the routine FLIM.
Need only be changed to a "decision block" for discriminating transmission files in the batch transmission mode. The routine FLST also
As shown in FIG. 7, instead of the judgment 14, the judgment 22 for judging the transmission file in the time designated transmission mode and the judgment 23 for judging that the designated transmission time is exceeded are judged 13 and the processing 15
Insert between the other, the rest may be the same as the routine FLIM.

FIG. 8 shows another example of routine FLIM, that is, routine FLIM.
1 is shown. In this routine FLIM1, after transmitting the immediate transmission file, the immediate transmission file of the same destination is searched and transmitted. That is, in the table search loop after processing 16, the judgment 24 for judging the immediate transmission file is inserted after the judgment 19 and the result of this judgment 24 is displayed.
The transmission file to be YES is transmitted by the process 16.

Now, setting the immediate transmission file search / transmission routine to the above-mentioned routine FLIM1 means that the transmission file of the same destination is searched from among those in which the same transmission mode is set. Therefore, a routine FLBK1 and a routine FLST1 for performing similar processing in other transmission modes are shown in FIGS. 9 and 10, respectively.

That is, the routine FLBK1 has the contents in which the determination 14 and the determination 24 of the routine FLIM1 are changed to the determination 25 and the determination 26 for determining the batch transmission file, respectively.

Also, the routine FLST1 is a routine F partially shown in FIG.
In LST, if the result of judgment 20 is NO, change to return to processing 17, and if the result of judgment 20 is YES, then a predetermined time (for example, 10 minutes) from the designated transmission time of the transmission file transmitted earlier. The determination 27 for determining the transmission file whose time in the range is set to the designated transmission time is performed, and the process returns to the process 16 and the image information is transmitted only when the result of the determination 27 is YES.

As a result, transmission files of the same destination that are subsequently transmitted are searched from among those for which the same transmission mode is set.

FIG. 11 shows another example of the routine FLIM, that is, the routine FLIM2. In this example, when an immediate transmission file is transmitted, if there is a batch transmission file with the same destination set, this batch transmission file is transmitted only when there is no immediate transmission file with another destination set. . By doing this, the routine FLIM shown in FIG.
Compared with, does not impede the immediacy (immediacy) of the instant transmission file.

That is, when the table search is performed in process 17 and there is a transmission file (decision 28), this transmission file is in the immediate transmission mode (the result of decision 29 is YES), and it is not the same destination (the result of decision 30 is NO) ends the process.

On the other hand, the transmission file searched is not in the immediate transmission mode (the result of judgment 29 is YES), the same destination is set (the result of judgment 32 is YES), and the transmission request exists (judgment 33).
If the result is YES, and the batch transmission mode is set (the result of determination 34 is YES), the process returns to process 16 and the transmission file is transmitted.

Also in this routine FLIM2, if the same destination exists in the immediate transmission mode (result of determination 30 is YES) and the transmission request is present (result of determination 31 is YES), the transmission file is transmitted.

If the destination station is communicating in the above-described process 15, the call is reissued after a certain period of time, but the number of re-calls is stored in the call count information CT, and the value of this call count information CT is a predetermined value. When it becomes (for example, 2 or 5), the transmission control relating to the image information file is interrupted, and the process moves to the transmission control of the next image information file. This is because the repeat transmission is repeated indefinitely or many times, and the broadcasting device MFX is sequentially
This is a measure for preventing the normal operation of the vehicle from being hindered.

Also, the page counter PC is incremented each time the image information for one page of the transmission original is sent. As a result, when the transmission is resumed after being interrupted, which page should be resumed can be easily determined.

[Effects] As described above, according to the present invention, if there is image information to which the same destination is set, the image information is transmitted successively, so that it is not necessary to repeat the transmission control procedure from the beginning, and as a result, the transmission line and the device. The advantage is that the usage efficiency of can be greatly improved.
