JPS6181048A - Page dividing communication system of telex message - Google Patents

Abstract

PURPOSE:To receive a code signal, namely, a telex message even at a reception terminal where the recording paper length is limited or a code buffer memory is not provided by providing a means which divides the code signal inputted from a transmission terminal to page units by a prescribed number of lines and transmits it to the reception terminal. CONSTITUTION:The code signal is transmitted from a transmission terminal 1 to a communication converter 5 through an exchange 4. After receiving this code signal by a reception control module 6, the communication converter 5 stores this code signal in a code buffer memory 7. A controller 8 counts one line by CR or LF in the code signal and edits the code signal in page units with b-number of lines as one page. The communication converter 5 discriminates the signal of the destination in the beginning of the code signal and is connected to a reception terminal 3 by the exchange 4. The code signal is transmitted to the reception terminal 3 in page units.

Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a telex message communication method, and in particular, by providing a means for dividing a code signal into pages of a predetermined number of lines and transmitting the same, A receiving terminal device with finite length recording (this also relates to a communication system capable of receiving code signals).

[Technical background of the invention]

FIG. 5 is a block diagram showing the configuration of a conventional telex telegram communication system. )2, transmit a telex message.

In this case, the receiving terminal 2 either has no limit on the length of the receiving recording paper or has a code memory capable of storing code signals of telex telegrams.

However, although the receiving terminal 3 can receive code signals of telex telegrams, it has a recording length limit and does not have a code buffer memory.

[Problems with background technology]

At this time, the transmitting terminal 1 can communicate with the receiving terminal 2 as described above, but since the receiving terminal 3 has a recording length limit and does not have a code buffer memory, the transmitting terminal 1 can communicate with the receiving terminal 2. There was a problem in that it was not possible to communicate with 3.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to eliminate the above-mentioned drawbacks and provide a telex telegram communication system that allows even a receiving terminal with a finite reception recording paper length and no code buffer memory to receive telex telegrams.

[Summary of the invention]

The present invention achieves the above object by providing means for dividing the code signal of a telex message into pages with a predetermined number of lines and transmitting them to a receiving terminal page by page.

[Embodiments of the invention]

Embodiments of the present invention will be described in detail below based on the drawings.

FIG. 1 is a block diagram showing the configuration of a telex telegram communication system according to an embodiment of the present invention. In the figure, elements that perform the same functions as the elements of the conventional telex telegram communication system shown in FIG. 5 are given the same numbers.

The feature of this embodiment is that the exchange 4 counts the number of lines of the code signal of the telex telegram, divides it into pages every certain number of lines, and transmits the code signal to the receiving terminal 3 for each page. The purpose of the present invention is to provide a communication conversion device 5 that performs the following steps.

FIG. 2 is a block diagram showing the configuration of the communication conversion device 5. As shown in FIG. As shown in the figure, the communication conversion device 5 includes a reception control module 6 that receives the code signal of the telex message, a code buffer memory 7, a control device 8 that divides the code signal into pages, and a code signal to the reception terminal 3. It consists of a transmission control module 9 for transmitting data.

Next, the operation of this embodiment will be explained. FIG. 3 is a flowchart showing the operation of this embodiment, and shows the operation when transmitting a telex message to the receiving terminal 3 which has the record length limit shown in FIG. 1 and does not have a code buffer memory. .

As shown in FIG. 3, first, in step S1, a code signal is transmitted from the transmitting terminal 1 to the communication converter 5 via the exchange 4. In the communication conversion device 5, the reception control module 6 (FIG. 2) receives this code signal, and then stores this code signal in the code buffer memory 7 (FIG. 2) (step s2).

Next, the control device 8 counts one row by CR-LF in the code signal (step S3), and then counts one row for every b rows.
The code signal is edited page by page (step s4).

FIG. 4 is a diagram schematically showing this page division, and FIG. 4(a) shows an input code signal, and FIG.
b) shows a code signal that has been divided into pages, and as shown in the figure, the page division is performed such that one line of character string a forms one page for every b line.

Next, the communication conversion device 5 determines the destination signal at the beginning of the code signal, and connects the communication conversion device e5 to the receiving terminal 3 via the exchange 4 (step S5). Then, the code signal is transmitted page by page to the receiving terminal 3 (step 86).

Note that the receiving terminal 3 performs code character conversion, but the character record in line b must be less than or equal to the maximum recording length of the receiving terminal 3. Furthermore, in this embodiment, a case has been described in which the communication conversion device 5 receives a code signal from the transmitting terminal 1, but regardless of the method, if the code signal is input to the code buffer memory 7, the communication converter 5 receives the code signal from the receiving terminal 3. You can send telex messages to.

〔Effect of the invention〕

As described above in detail and concretely, according to the present invention, by providing means for dividing the code signal input from the transmitting terminal into individual pages for each predetermined number of lines and transmitting the divided pages to the receiving terminal. , a receiving terminal with a limited recording paper length,
Even receiving terminals that do not have a code buffer memory can receive code signals, that is, telex messages.
