Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for outputting unsent documents in a broadcasting device.

The broadcast device inputs the manuscript to be broadcast from the center to multiple terminals into the broadcast facsimile transceiver (hereinafter referred to as the facsimile device) within the center.
The image information obtained thereby is temporarily stored in memory. The plurality of documents sequentially stored in this manner are sent to a terminal for each document by operating the operation section.

In such a broadcast device, there is a limit to the number of documents that can be stored in the memory, so documents whose broadcast communication to each terminal is not completed due to busy lines or line failures (hereinafter referred to as unsent documents) is cleared from memory after several attempts to send to these terminals.

Conventionally, unsent documents that would be deleted from memory in such cases would be sent to the telephone line with the center itself as the dial destination, and the data regarding these unsent documents would be sent to the center's facsimile machine via the nearest telephone office. , and was played back by the receiving function of the facsimile machine. In this way, conventional broadcasting devices use telephone lines to reproduce image information about unsent documents, which increases the traffic density and requires telephone charges each time. It was hot.

The present invention was made in view of the above circumstances, and
It is an object of the present invention to provide an unsent output method that can send unsent originals to a facsimile machine at low cost. The present invention achieves the above-mentioned object by directly inputting data related to unsent documents outputted from the memory, that is, unsent outputs, to a facsimile machine in a center without going through a telephone exchange.

The present invention will be explained in detail with reference to Examples below.

In Figure 1 showing the configuration of the broadcast system,
1 is a center broadcasting device, 2 is an exchange, and 3 and 4 are telephone lines; 3 is for transmission and 4 is for reception. In the broadcasting device 1, 11 is an operation panel;
12 is a broadcast facsimile device, 13 is a telephone,
A network control device 14 has an automatic dialing function and connects the facsimile device 12 or the telephone 13 to the telephone line 3 selectively. 15 is a central processing unit that controls the entire broadcasting device; 16, 17, 18;
are an interface for an operation unit, a facsimile interface, and an interface for network control, respectively, and 19 is an input/output bus. 20 is the main memory,
21 is an image memory; 22 is a memory bus; the main memory 20 stores control programs and various control data necessary for control operations of the central processing unit; image information is exchanged between the image memory 21 and the facsimile device 12; It also has an area as a buffer memory that is used when necessary.

When broadcasting, the operation panel 11 is operated,
When data indicating a plurality of destinations and input instructions is given, this data is sent to the central processing unit 15 through the operating unit interface 16 and the input/output bus 19. The central processing unit 15 stores destination data in the image memory 21 and provides input instruction data to the facsimile device 12 through the facsimile interface 17 . If a transmission document is set, the facsimile device 12 reads the original and processes the image signal obtained by the reading. The processed image information is sent to the central processing unit 15 via the facsimile interface 17.
sent to. The central processing unit 15 sequentially stores image information in the image memory 21 using the main memory 20 as a buffer memory.

In this way, all the image information is stored in the image memory 21, and after becoming ready for transmission, when output instruction data is given from the operation panel 11, the central processing unit 15 outputs the plurality of image information stored in the image memory 21. One of the destination data is read out, converted to dial number data, and this dial number data is provided to the network control device 14 via the network control interface 18. Network control device 14
After closing the DC loop for the telephone line 3 and making a call, it sends a dial signal based on this data to the exchange 2. When an exchange connection is made to a telephone line to which a terminal (not shown) is connected in the exchange 2 and a call is received at the terminal, the network control device 14 detects this and sends an incoming call detection signal to the central processing unit 15. At the same time, the connection between the facsimile device 12 and the telephone line 3 is controlled.

The central processing unit 15 accesses the image memory 21, reads out image information using the main memory 20 as a buffer memory, and sends it to the facsimile device 12. The facsimile device 12 modulates the image information at a predetermined modulation rate and sends a modulated signal to the telephone line 3 via the network control device 14. All the image information is sent out, and in addition, if necessary, a control signal is sent to the control device 14 to indicate the end of sending out the image information and to open the telephone line 3.

When the transmission of image information to one terminal is completed in this way, automatic dialing is performed for the next terminal, and when the terminal is connected, the same image information is transmitted in the same way. Broadcast communication is subsequently performed to a plurality of terminals in the same manner, but it may be impossible to transmit the image information because some or all of the other terminals are receiving data or are out of order. In such a case, after a predetermined period of time has elapsed, broadcast communication is attempted again to the terminals that have not yet received the message. When transmission to these terminals becomes impossible again, this connection test is repeated several times.

By the way, if such a state is repeated many times for various originals, the number of unsent originals increases in the image memory 21, and the facsimile device 12
Since it is no longer possible to input a new manuscript, a problem arises in the operation of the broadcast system. For this reason, a section is provided in the control data storage area of the main memory 20 to store the number of attempted transmissions of unsent documents for each destination. If this is not possible, the image information for the unsent document is sent to the facsimile device 1, provided that the number of times the transmission has been done reaches a predetermined number.
2, and its receiving function reproduces and records the data.

That is, when it is determined that a particular document is to be sent to the facsimile device 12, the central processing unit 15 first sends a direct connection signal A to the facsimile device 12 through the facsimile interface 17, as shown in FIG. If the facsimile device 12 is not receiving data, the central processing unit 1
The central processing unit 15 sends a direct response signal B to the central processing unit 15.
Wait for the image information sent from. When the central processing unit 15 detects the direct connection response signal sent from the facsimile device 12, it accesses the image memory 21 and transfers the image information about the unsent document to the facsimile device 12 through the facsimile interface 17. do.

On the other hand, if the facsimile device 12 is receiving the direct connection signal A when it is sent to the facsimile device 6, the facsimile device 12 does not send out the direct connection response signal. In this case, since the central processing unit 15 cannot detect the direct connection response signal, it stops sending out the direct connection signal A after a predetermined period of time has elapsed. Then, after a certain period of time has elapsed, the direct connection signal A is sent to the facsimile device 12 again. In this way, the direct connection response signal B
The above operations are repeated until detected by the central processing unit 15.

After the central processing unit 15 detects the direct connection response signal B, both the direct connection signal A and the direct connection response signal B remain on (exist) until the image information transfer is completed, and the image information transfer is completed. At this point, it turns off.

FIG. 3 is a diagram for explaining in more detail the untransmitted output method described above.

During broadcast communication, as mentioned above, the central processing unit 1
5 to the input/output bus 19, the image information is sent to the modulator 5 via the facsimile interface 17 and the main body 51 in the facsimile device 12.
2. This modulated image information is sent to the network control device 14 and the telephone line 3 for transmission.
is transmitted to the other party's terminal via. In addition, the main body 51
The broken line inside means the connection path at this time, and when a document is input, a connection path is formed from the image signal processing section in the main body to the facsimile interface 17.

On the other hand, a signal transmitted from the other party's terminal through the receiving telephone line 4 is input to the main body 51 via the incoming call detection circuit 54 and the demodulator 53, and is reproduced and recorded. The incoming call detection circuit 54 includes a central processing unit 15.
A direct connection signal A is input from the telephone line 4, and when the direct connection signal A is on, the telephone line 4 loses its incoming call function. In other words, even if the other party's terminal calls the center in this state, the center will be busy.
Image information cannot be transmitted from the other party's terminal to the facsimile device 12.

The incoming call detection circuit 54 generates a direct connection response signal B that turns on when the direct connection signal A turns on and there is no incoming call function. This signal B is the central processing unit 1
5, and the central processing unit 15 accesses the image memory 21 in response to this, and sends the unsent original to the facsimile device 12. At this time, since the direct connection signal A remains on, the untransmitted output passes through the AND circuit 55 as it is and is input to the receiving section of the main body 51. The main body 51 reproduces this unsent document.

Here, the image data input means corresponds to the facsimile interface 17, and the input data selection means corresponds to the central processing unit 15, the incoming call detection circuit 54, and the AND circuit 55.

As described above, according to the present invention, it is possible to send unsent originals to a facsimile device without using a telephone line, without having to significantly change the broadcasting device.
Furthermore, if the number of transmission tests for unsent documents is counted as explained in the example, and the count is transferred to the facsimile machine when the count reaches a certain value, the management of unsent documents can be automated and the operator No operation required. Of course, when the central processing unit decides to transfer unsent originals to the facsimile machine, it may also use a method other than counting.For example, the central processing unit may periodically grasp the storage status of unsent originals in the image memory. It is also effective to transfer unsent originals to the facsimile machine in order of age when the number of unsent originals exceeds a certain level.

Note that the transfer of unsent documents to the facsimile device does not always have to be performed automatically, and a method may be adopted in which a designated document is transferred to the facsimile device by an operator's operation on the operation panel. In this case, the operator can freely determine the order of transfer of unsent documents.

Further, in the embodiment, only the unsent originals are reproduced and recorded, but in addition to this, information on destinations to which the originals have not been sent may also be recorded.
This can be realized by representing the destination information in a code, for example, and by providing a storage unit that stores the code in the form of image information in advance.
