FIG. 5 shows a conventional configuration of the facsimile signal transmitting device 103.

In the figure, reference numeral 11 denotes a computer that controls the entire facsimile signal transmission device 103. This computer
A keyboard 12 constituting an input device is connected to 11.
The keyboard 12 is used to input control information, data, and the like.

Reference numeral 13 denotes a document input unit for inputting the type information to be transmitted to the computer 11 as digital data. As the document input means 13, an image scanner, a word processor, a telephone line facsimile, or the like is used. Hereinafter, the image scanner will be described as an example.

Reference numeral 14 denotes a facsimile which converts digital data of type information input to the computer 11 from the document input means 13 into facsimile data by performing compression coding or adding an error correction code by a dedicated IC or software processing. It is a data creation means.

Reference numeral 15 denotes the facsimile data Sf and the multiplexer 104.
An output I / F circuit for outputting in accordance with the input interface (see FIG. 4).

In the above configuration, when an operator sets a document to be transmitted on the document input means 13 and instructs the computer 11 to start transmission from the keyboard 12, the document is read by the computer 11 as image pattern data 2b.
The computer 11 obtains the facsimile data 2d through the facsimile data creating means 14 using the image pattern data 2b as it is as the data 2c. Computer 11
Sends the data 2d from the data port to the output I / F circuit 15 as data 2e to which control data indicating the start and end of the document is added at the beginning and end of the data 2d. The data 2e is output from the output I / F circuit 15 in accordance with the input interface of the multiplexer 104, and transmitted as facsimile data Sf (see FIG. 4).

[Problems to be solved by the invention]

Here, when transmitting type information that complements video information and audio information, the facsimile data Sf is transmitted at the same time as the transmission of the video signal Sv and the audio signal Sa. Therefore, the facsimile data Sf is transmitted at predetermined intervals in accordance with the transmission of the video signal Sv and the audio signal Sa.

In the facsimile signal transmitting apparatus shown in FIG. 5, the operator needs to instruct the computer 11 to start transmission by using the keyboard 12 every time a document is transmitted.

Therefore, when sending at an interval time, the operator must always wait and manage the time, and instruct the start of sending at each time to be sent, which is a great burden.

Accordingly, the present invention provides a facsimile signal transmitting device that can reduce the burden on the operator.

[Means for solving the problem]

According to the present invention, original input means for inputting type information to be transmitted as digital data, facsimile data generating means for generating facsimile data from digital data input from the original input means, and output from the facsimile data generating means Data storage means capable of storing a plurality of facsimile data, time table creation means for creating a time table of facsimile transmission time and facsimile data stored in the data storage means, and management of the transmission time and clock time of the time table And data transmission means for reading out and transmitting facsimile data corresponding to the transmission time from the data storage means.

[Action]

In the above configuration, the transmission time of the time table and the time of the clock are managed, and at the transmission time, the corresponding facsimile data is read from the data storage means and automatically transmitted.

Therefore, even when transmission is performed at an interval time, the operator does not need to instruct transmission start at each transmission time, and does not need to always wait.

〔Example〕

Hereinafter, an embodiment of the present invention will be described with reference to FIG. In FIG. 1, portions corresponding to those in FIG. 5 are denoted by the same reference numerals, and detailed description thereof will be omitted.

In this example, a computer 11, a keyboard 12, an original input means 13, a facsimile data creating means 14, an output I /
In addition to the F circuit 15, a large-capacity data storage means 16 such as a hard disk for storing created facsimile data.
Is provided, and a clock 17 is provided in the computer 11. Reference numeral 18 denotes a display means such as a CRT.

Next, the four originals A, B, C, and D are
The operation of this example will be described with an example in which the document is transmitted at 10:00, the document B is transmitted at 11:15, the document C is transmitted at 12:30, and the document D is transmitted at 12:35.

First, an operation of storing and registering digital data of a document in advance will be described.

In this case, when the digital data of the originals A, B, C, and D are converted into facsimile data,
It is assumed that the data has a capacity of 480 kbytes, 1200 kbytes, and 600 kbytes, and is stored and registered under the names of 100, 200, 300, and 400, respectively.

The operator places the document A on the document input means 13, inputs a name “100” for registering the input document from the keyboard 12 to the computer 11, and instructs input of the document.
The digital data 1b of the document A is input from 3 to the computer 11. The computer 11 converts the data 1b into facsimile data, passes the data 1b directly to the facsimile data creating means 14 as data 1c, and converts the facsimile data into a facsimile data having a capacity of 720 kbytes.
1d is obtained. The computer 11 sends the facsimile data 1d to the large-capacity data storage means 16 as it is as data 1g, and sends the registered name "10"
"0" is stored and registered in the large capacity data storage means 16.

Similarly, the digital data of the original B is converted to facsimile data and becomes 480 kbytes of facsimile data, and has a registered name of "200". By the name, the digital data of the original D is 600k bytes of facsimile data, "400"
Are registered and stored in the large-capacity data storage means 16, respectively.

 Next, the time table will be described.

As shown in FIG. 2, the time table has fields for a document name, a time at which the document is started to be transmitted, and a time at which the transmission is completed. The sending time and the original name are input from the keyboard 12 in the order of sending. The sending end time is obtained by calculating the sending time of this document from the data capacity of the sending document by the computer 11 and adding this to the sending time. In the example of FIG. 2, the sending speed of facsimile data is 2k
The transmission time is calculated using the equation (1).

T = C / (2 × 60) (1) T: transmission time (minutes) C: data capacity (k bytes) A procedure for creating such a time table will be described.

First, the first transmission start time 10:00 and the transmission original name "100"
Is input from the keyboard 12 by the operator. Then, the computer 11 substitutes the data capacity of 720 kbytes of the original into the equation (1) to calculate a transmission time of 6 minutes, obtains the transmission start time, obtains the transmission end time 10:06, and writes it in the time table. .

Subsequently, the second transmission start time 11:15 and the transmission original name "20
Input "0" from the keyboard 12. Computer 11
The first transmission end time 10:06 is compared with the second transmission start time 11:15 to confirm that the transmissions do not overlap. Further, the transmission end time 11:19 is obtained from the data capacity of the second document of 480 kbytes and is written in the time table.

Subsequently, the third transmission start time 12:30 and the transmission original name "30
Input "0" from the keyboard 12. Computer 11
The second transmission end time 11:19 and the third transmission start time 12:30 are compared to confirm that the transmissions do not overlap. Further, the third transmission end time 12:40 is obtained from the data capacity of the third document, 1200 kbytes, and is written in the time table.

Subsequently, the fourth transmission start time 12:35 and the transmission original name “40
Enter "0". The computer 11 compares the third transmission end time 12:40 with the fourth transmission start time 12:35, finds an overlap in transmission, and displays a warning on the display means 18. This warning is given by, for example, a color change, blinking, or an error message. Note that, even if not described above, the timetable being created is displayed on the display means 18 when the timetable is created.

The operator confirms the warning described above and changes the setting of the time table so that the transmissions do not overlap. Here, a case will be described where the fourth transmission start time is changed to 12:50 and input again. Then, the computer 11 compares the third transmission end time 12:40 with the fourth transmission start time 12:50,
After confirming that there is no overlap in the transmission, the fourth transmission end time 12:55 is obtained from the data volume of the transmitted document of 600 kbytes and written in the time table.

In this way, four transmissions are set in the time table (shown in FIG. 2).

This time table is created and stored on the system memory of the computer 11, the large-capacity data storage means 16, or the like.

In this way, before the sending time, the storage registration of the facsimile data of the sending original and the creation of the time table are performed.

The sending process is started when the operator instructs the computer 11 to start sending the time table from the keyboard 12. This instruction is performed before the first transmission time registered in the time table.

This sending operation will be described along the processing flow of the computer 11 (shown in FIG. 3).

In step 51, the computer 11 sets the first transmission start time 1 registered in the time table (shown in FIG. 2).
0:00 and the current time xx: xx of the clock 17 of the computer,
If they are not equal, the determination in step 51 is repeated.

In step 52, the computer 11 obtains the first sentence document name "100" by referring to the time table, and stores the facsimile data of the sentence document name "100" in the large-capacity data storage unit 1.
Read from step 6 and proceed to step 53.

In step 53, the computer 11 adds control data indicating the start and end of the original data to the beginning and end of the read facsimile data, and proceeds to step.

In step 54, the computer 11 sends out the facsimile data to which the control data has been added to the output I / F circuit 15 through the data port as data 1e, and proceeds to step 55. At this time, the data 1e is output from the output I / F circuit 15 to the multiplexer 104.
And output it as facsimile data Sf (see FIG. 4).

In step 55, it is determined whether there is the next transmission. In this example, since there is the second transmission, the process proceeds to step 51. In step 51, the second transmission start time 11: 1 is obtained from the time table.
5 and the current time xx: xx of the clock 17 of the computer 11 are compared, a second transmission is performed in the same manner as the first transmission, and the process proceeds to step 55.

In step 55, since there is the third transmission as the next transmission, the process proceeds to step 51. In step 51, the third transmission start time 12:30 is compared with the time xx: xx of the current time 17 of the computer 11 from the time table, and the third transmission is performed in the same manner as the first transmission, and the process proceeds to step 55. .

In step 55, since there is the fourth transmission as the next transmission, the process proceeds to step 51. In step 51, the fourth transmission start time 12:50 of the time table is compared with the current time xx: xx of the clock 17 of the computer 11, and then the fourth transmission is performed in the same manner as the first transmission.

In step 55, since there is no next transmission, the processing is terminated, and the four transmissions are completed.

As described above, in the present example, when sending is performed at an interval time, the facsimile data of the document to be sent is stored and registered, and a time table is created before the first sending time. The facsimile data Sf corresponding to the time is automatically and sequentially transmitted. Therefore, the operator does not need to instruct transmission start at each transmission time. That is, it is not necessary to always wait as in the conventional example, and the burden on the operator can be greatly reduced.

In the above-described embodiment, one transmission is performed for one document. However, the present invention can be applied to a case where one transmission is performed for a plurality of documents.

〔The invention's effect〕

As described above, according to the present invention, the transmission time of the time table and the time of the clock are managed, and at the transmission time, the corresponding facsimile data is read from the data storage means and automatically transmitted. Even when the transmission is performed at an interval time, the operator does not need to instruct the start of transmission at each transmission time, and does not have to always wait, so that the burden on the operator can be greatly reduced. When creating the time table, the transmission time is calculated based on the data volume of the document to be transmitted, and the transmission time is added to the transmission start time given as data to obtain the transmission end time. The transmission end time is written together with the time, and when the transmission start time of the next original is given as data, the transmission end time is compared with the transmission end time of the previous original to check the overlap of the transmission times. Thus, it is possible to prevent a transmission error at the time of facsimile data transmission due to overlapping transmission times.
