【発明の詳細な説明】
(1) 発明の技術分野
本発明は、電話交換網を利用するフアクシミリ
伝送方式に関し、特に同報時の回線使用コストを
低減しようとするものである。DETAILED DESCRIPTION OF THE INVENTION (1) Technical Field of the Invention The present invention relates to a facsimile transmission system that utilizes a telephone exchange network, and is particularly intended to reduce line usage costs during broadcast broadcasting.
(2) 技術の背景

性が強い。(2) Technical background In facsimile transmission, the same message may be sent to multiple destinations. This is generally called broadcasting, but when using a switched telephone network, line usage charges become an issue. In other words, in the case of one-to-one transmission, the line usage fee is uniquely determined. However, if broadcasting is performed by repeating this one-to-one transmission, there is a strong possibility that the line usage fee in that case will be the highest.

る。(3) Prior art and problems In other words, as shown in Figure 1, the facsimile device FAXa communicates with FAXb via the telephone switching network NW.
Previously, when sending the same message to FAXc, line L1 was used.
From FAXa to FAXb, and from FAXa on line L 2
It is common to transmit to FAXc. However,
In some cases, the overall line charge may be cheaper if you send a message from FAXa to FAXb on line L1 , and then send the same message from FAXb to FAXc on line L3 . However, in conventional facsimile transmission, such consideration is not usually taken.

A buffer that stores messages, a function that determines the next device that can transmit data using the minimum cost route from the remaining destination information given from the previous device, and a function that attaches the remaining destination information to the data in the buffer and sends it to the next device. The device is characterized by having a function of transmitting information to.

安価であると判断されて選択されたものである。(6) Embodiments of the Invention The present invention will be described in detail below with reference to illustrated embodiments. FIG. 2 shows an embodiment of the present invention, in which a broadcast is sent from a facsimile device FAXa to FAXb and FAXc. In this example, first, a message is sent from FAXa to FAXb via line L1 , which then prints it and also transfers it to FAXc via line L3 . The lines L 1 and L 3 used at this time are cheaper than broadcasting in parallel on lines L 1 and L 2 as shown in Figure 1, or serially transmitting on lines L 2 and L 3 . It was selected because it was determined that there was.

アである。 In the case of serial transmission in this manner, the device FAXb serving as a relay point needs to use its output document as the document to be transmitted to the next device FAXc, or a buffer Mb is required to store the received message from the previous device FAXa. Relaying using a buffer is advantageous in order not to degrade the final image quality in serial transmission. Ma and Mc are similar buffers provided with the assumption that each device will serve as a relay point.

~fb 3 , fc 1 ~ fc 5 , fd 1 ~ fd 4 are normal facsimile,
A to D are devices above these that have a storage function and are capable of facsimile transmission. Therefore, for example, a combination of device A and one facsimile fa1 corresponds to the facsimile device FAXa in FIG. When a plurality of facsimiles fa1 to fa4 are connected to the lower level, device A (and the other devices B to D as well) has these selection functions. The devices A to D are connected to each other by a switching network NW. The charge for each line is (1),

置へ同じ電文が直列伝送される。 In such a case, the problem is the handling of destination information and the logic of route selection. The destination information can be written in a document destination information field 11 provided in a part of the document 10 as shown in FIG. 4, or added to the control signal for the transmission procedure as shown in FIG. introduce. In the case of Fig. 4, field 1 is used for devices A, B, ... that have facsimile transmission functions.
Control 1. That is, when a document with all destinations marked is sent from the sender, the device that receives it searches for the most suitable next device from field 11, and sends the document with the remaining destinations marked, including the next device, to the next device. Transmit to device. As each device repeats this, the number of "remaining destinations" decreases one by one, and the same message is serially transmitted to the final device.

する。 Figure 5 shows the transmission sequence of the binary code signal system for facsimile control procedures, where DIS is a digital identification signal, DCS is a digital command signal,
CFR is a reception readiness confirmation signal. In such a transmission sequence (phases B, C, and D), destination information can be added to the digital command signal DCS and transmitted. This additional information is controlled by devices A, B, . . . having a facsimile transmission function. In other words, the device that has been notified of all destination information as additional information from the sender searches for the optimal next device by recognizing the additional information, and
The remaining destination information including the next device is notified as additional information to the next device, and the document is sent.

Explain. For example, assuming a system as shown in FIG. 6a, tables T A , T B , . . . are provided for each device A, B, . . . as shown in FIG. 6 b and c when the system is constructed. These tables T A , T B , . . . indicate when each device A, B, . . . is a transmission source, a first relay point, a second relay point, etc., respectively.
is stored for all cases. The content is such that the remaining destination information from the previous device is searched as all destinations, and each column is filled with the cheapest next device (next destination) and other destinations, taking into consideration each line charge. The destination is written. Therefore, for example, when sending a document from device A to device B and C, the table
The destination is determined to be device C from the first column of T A , and the document to which all destination information (C and B) including the next destination C and other destinations B is added is sent to device C. Device C can recognize that B is the only destination other than its own device C (in this case, table T C
), the document is sent to the next device B with only the destination information (B) added. Since device B has no destination other than itself, it recognizes that it is the terminal, and ends the series of transmissions. Like this A→
If it is transmitted in series from C to B, the line charge will be 5+3=8, but if it is transmitted in parallel from A to B and A to C, the line charge will increase to 5+7=12.

The determination circuit 23 searches the table 24 using the given destination information to determine the next destination, and the automatic transmission and transmission circuit 25 transmits the original in the buffer memory 22 and the destination information from the table 24 to the next device. let In the example shown in FIG. 8, non-urgent documents are transmitted to the next device at night at a discounted rate. Reference numeral 26 denotes an urgency determination circuit, which operates in the same manner as in FIG. 7 if it is determined that the document is an urgent document. On the other hand, if it is determined that it is not urgent (no), the accumulation time control circuit 27 and the timer 2
At step 8, the original stored in the buffer memory 22 is transmitted to the apparatus after the line charge becomes discounted.
