Abstract

PURPOSE:To obtain the accurate information on the remaining capacity of a memory by securing the equality between the number of characters included in one line used as a basis for calculation of the number of lines to be displayed for the memory remaining capacity and the set value of the write margin. CONSTITUTION:A main control part 11 includes a memory remaining capacity information register 14 which stores the capacity of a telegram memory part 21 or an external memory part 22 in the form of the number of characters, a write margin setting register 12 which stores the write margin set value inputted from an input part 41, and a memory remaining line number register 13 which stores the memory remaining capacity in the form of the number of lines. When the write margin is set, the memory remaining capacity information is divided by the set value of the write margin. The result of this calculation is displayed at a display part as the number of remaining lines of the memory. Thus the coincidence is always secured between the line number display of the memory remaining capacity and the actual memory remaining capacity.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method for displaying remaining memory capacity in a terminal device that is equipped with a storage unit and a display unit for character information, and particularly relates to a method for displaying remaining memory capacity in a terminal device that is equipped with a storage unit for character information and a display unit. This is related to displaying the remaining memory capacity as the number of remaining lines.

[Prior Art] Terminal devices equipped with a storage section and a display section for character information include display devices, audio devices, personal computers (PCs), word processors,
There are various types such as typewriters and teleprinters. Here, among these devices, a device that creates a data body (text) to be transmitted, first stores it in a storage section, and then transmits it to a partner station, particularly a teleprinter, will be explained.

Conventionally, teleprinters display remaining memory capacity on a display for the operator. While an operator is creating a text, he or she may want to know the amount of memory available for text creation, that is, the remaining amount of memory. This is because even if a text is created that exceeds the remaining capacity of the memory, the excess amount cannot be transmitted to the partner station, and the creation will be wasted.

Specifically, the number of remaining lines in the memory was displayed as the number of remaining lines in the memory on the CRT display, which was a display section.

For example, if the remaining memory capacity is 5000 characters, 5000
Since 69 = 72.4637, the display will be "72°".

Here, the value 69'' is the conventional maximum number of standard characters in one line for teleprinters.

Furthermore, the reason why the remaining capacity of the memory is displayed as the number of remaining lines rather than the number of remaining characters is because if it is displayed as the number of characters, the number of display digits increases, making it difficult for the operator to recognize it in a short time. Furthermore, displaying the remaining memory capacity in terms of the number of lines has also been a standard display method for teleprinters.

However, the conventional method of dividing the remaining number of characters in memory by the standard maximum number of characters in one line and displaying the remaining memory capacity as the number of remaining lines has the following drawbacks.

Some teleprinters have an editing function, that is, a light margin function, that allows you to set the maximum number of characters per line to an arbitrary number rather than a fixed value. This teleprinter has a problem where when the maximum number of characters per line is set to something other than ``69'' characters using the light margin function, the displayed number of lines of remaining memory capacity does not match the actual remaining capacity. there were.

For example, if the remaining memory capacity is 5000 characters and the maximum number of characters per line is set to 80 characters, 500 (
Since 169=72.4637, the number '72' is displayed.

However, in reality, it is 500 (180=62.5...), so the number of remaining lines should be "62". If the number of characters is fixed in this way, the display and the actual number will not match.

By the way, unlike terminal devices such as personal computers and wharf terminals, which have a large storage capacity and usually create documents or text page by page, teleprinters have a relatively small storage capacity (3
(approximately 2K), and there is no concept of pages (the I-text single-sheet format is used, and continuous roll paper is used for printing).

Therefore, especially with teleprinters, as mentioned above, if the displayed number of lines remaining in memory is larger than the actual number of lines remaining, the operator may suddenly realize that he or she thought he or she could still input data. This leads to a situation where input is no longer accepted. In this case, unlike the case where the text can be processed page by page, the entire text may be wasted and the text may have to be rewritten from the beginning to fit within the memory capacity.

[Problems to be Solved by the Invention] As described above, in the conventional system in which the number of characters in one line, which is the basis for calculating the number of remaining lines in memory, is fixed, and the number of lines remaining in memory is displayed, the number of characters remaining in memory is displayed. If the number of characters and the set number of characters do not match, the displayed number of remaining lines may not match the actual number of remaining lines, which is a drawback.

An object of the present invention is to eliminate the above-mentioned drawbacks of the prior art by making the maximum number of characters in one line, which is the basis for calculating the display of the number of remaining lines in memory, equal to the write margin setting value, even when the write margin setting value changes. To provide a display method for remaining memory capacity that allows an operator to obtain accurate information without causing a mismatch between the display of the number of lines of remaining memory capacity and the actual remaining capacity.

[Means for Solving the Problems] A display method for displaying remaining memory capacity of the present invention includes a storage section that stores character information, and a display section that displays character information with a specified maximum number of characters in one line, In a terminal device where the maximum number of characters in a line can be set arbitrarily, the remaining memory capacity in the storage section prepared for creating character information is divided by the write margin setting value that determines the maximum number of characters in one line, and the result is divided. '' The number of lines remaining in the remaining memory capacity is displayed on the display section.

Here, the character information includes symbols, figures, etc. in addition to characters.

Furthermore, the right margin is the number of characters that can be placed in one line, and the right margin setting value is the maximum number of characters that can be placed in one line.

1 Effect] When the write margin is set, the remaining memory capacity is divided by the setting value, and the result of the calculation is displayed on the display unit as the number of remaining lines in the memory.

Further, when the write margin setting value or the remaining memory capacity changes, the above-mentioned arithmetic processing is performed again, so the current number of remaining memory lines is displayed on the display section.

In this way, the remaining memory capacity is calculated based on the currently set write margin, so the line number display of the remaining memory capacity always matches the actual remaining capacity.

[Embodiment 1] An embodiment of the present invention will be described below with reference to FIGS. 1 to 5.

FIG. 1 is a block diagram showing an example of the method for displaying remaining memory capacity of the present invention applied to a teleprinter.

Reference numeral 41 indicates an input section for creating text and setting a light margin, and is composed of a keyboard. 21
is a message storage unit that stores created text, and is composed of semiconductor memory.

Reference numeral 31 denotes a display section for the operator to visually check the text being created or already stored, and is comprised of, for example, a 12-inch CRT display.

Furthermore, if necessary, an external storage device 22 consisting of a floppy disk or the like. Printing device 51 to which roll paper is attached. Line control unit 61 that controls transmission of external line data
are connected to the main control section 11, respectively. This main control section 1
1, the external storage device 22. The printing device 511 and the line control section 61 are connected to the input section 41. The message storage section 212 is controlled together with the display section 31.

The main control unit 11 has a message storage unit 21 or an external storage unit 2.
2, a remaining memory capacity register 14 that stores the remaining memory capacity in the number of characters, a write margin setting register 12 that stores the write margin setting value input from the human power section 41, and a memory that stores the remaining memory capacity in the number of lines. It has a remaining line number register 13.

Next, the operation of the above-mentioned configuration will be explained using FIGS. 2 and 3.

When the teleprinter (apparatus) is started up, the initial flow shown in FIG. 2 is carried out, and then text creation 5 collection etc. are carried out based on the flow shown in FIG. 3.

First, FIG. 2 will be explained.

The operator first puts the device into text creation mode, and the main control unit 11 determines whether the mode selected by the operator is this text creation mode (SPI).

When it is determined that the text creation mode is selected, the main control unit 11
Under its control, the parameter setting screen is displayed on the display unit 31 (see FIGS. 4 and 5), the standard value is stored in the light margin setting register 12, and the remaining memory capacity register 14 is stored in the message storage unit 21 or external The remaining capacity is stored in the storage unit 22 (SF3, 5P3).

Next, the operator inputs parameters by operating the input unit 41 while looking at the display unit 31, and the manually input parameters are captured and stored in the main control unit 11 (SF4).

Further, a write margin position is specified as necessary, and the main control unit 11 determines whether a write margin position has been specified (SF3).

When a write margin is specified, the main control unit 11 takes in the write margin setting value input from the input unit 41 and stores it in the write margin setting register 12 as a new write margin value to replace the standard value described above. (SF3).

After the new write margin setting value is stored, or when no write margin is specified, the main control unit 11 reads the remaining memory capacity in characters from the remaining memory capacity register 14, and reads the remaining memory capacity from the write margin setting register 12 first. Read the memorized write margin setting value (SF3)
.

Next, the main control unit 11 divides the read number of characters of the remaining memory capacity by the write margin setting value, stores the calculation result as the number of remaining memory lines in the remaining memory line number register 13, and displays it on the display unit 31. (SF8,5P
9).

This completes the initial flow.

Next, text creation 2 is performed following the initial flow.
The flow of binding collection etc. will be explained with reference to FIG. Monitor value changes.

First, the main control unit 11 reads the remaining memory capacity of the message storage unit 21 or the external storage device 22, and compares it with the remaining memory capacity previously read and stored in the remaining memory capacity register 14 to determine whether the remaining memory capacity has changed. Decide whether or not (SP
IO).

When the remaining memory capacity changes, the main control unit 11 takes in the remaining memory capacity of the message storage unit 21 or the external storage unit 22, and sets it as the current remaining memory capacity, replacing the previously stored remaining memory capacity. Store in register 14 (SPII).

The main control unit 11 also controls, during text creation or editing,
The write margin setting value input from the input unit 41 is taken in and compared with the write margin setting value previously stored in the write margin setting register 12 to determine whether the operator has changed the write margin setting value ( St)
12).

When the write margin setting value is changed, the main control unit 11 inputs the write margin setting value imported into the main control unit 11 into the write margin setting register as a new write margin setting value that replaces the previously stored write margin setting value. 12 (SP1, 3).

When the remaining memory capacity changes or the write margin setting value is changed, the main control unit 11 reads the remaining memory capacity in characters from the remaining memory capacity register 14, and reads the previously stored line from the write margin setting register 12. ]・Read out the margin setting value (S P 14)
.

Next, the main control unit 11 divides the read number of characters of the remaining memory capacity by the write margin setting value, stores the calculation result as the number of remaining memory lines in the remaining memory line number register 13, and causes the display unit 31 to display the result. (SPl, !5,
5p16), then return to the first step 5PIQ.

On the other hand, when there is no change in the remaining memory capacity or change in the write margin setting value, it is determined whether or not the text creation 2 binding collection etc. has been completed by pressing the end key of the input section 41 (SP1
7) If no key has been pressed, return to step 5pio and repeat the above-described flow, and if a key has been pressed, the process ends.

4 and 5 show the parameter setting screen of the display unit 31. In FIG. 4, the remaining memory capacity is "105.363".
``In the case of text, the light margin setting value is ' 6
Fig. 5 shows an example of displaying the number of remaining memory lines "1,527" when the remaining memory capacity is "1,527" when the write margin setting value is "80" when the remaining memory capacity is the same as in Fig. 4.
An example of displaying the number of remaining memory lines ''[317'' when `` is shown is shown below.

It is easy to see that the difference between the two is ``210'' lines.In other words, the operator who was creating text with the light margin setting value ``80°'' believed the conventional display, which always calculated with ``69''. In some cases, even though the remaining line "'210" was still displayed, I had the experience of suddenly not being able to do it manually.

As described above, according to this embodiment, the value of the number of lines, which is the basis for calculating the number of lines remaining in memory, is not fixed to the standard maximum number of characters in one line, but is set to the currently set light margin setting value. Therefore, even if the write margin setting value is changed, the calculated number of remaining memory lines will be the correct value, and therefore the number of remaining memory lines displayed on the display section 31 will be different from the actual number of remaining lines. always matches. In this way, the displayed number of remaining lines in memory matches the actual number of remaining lines, so it is especially useful for teleprinters that have a relatively small storage capacity (1 text, 1 page), and the operator is still There will be no more cases where you thought you could input something, but suddenly your input is no longer accepted, or where an entire piece of text is wasted and you have to re-enter it from the beginning.

In addition, when the operator creates or edits text and the remaining memory capacity changes, calculations are performed again based on the remaining memory capacity after the change, so even if the remaining memory capacity changes, the correct A remaining line number display is displayed on the display section 31.

Furthermore, even if the operator changes the light margin setting value midway, the calculation is performed again based on the changed light margin setting value, so even if the light margin setting value changes, the remaining rows are always correct. A numerical display is displayed on the display section 31.

In addition, although the terminal device was described as a teleprinter in the above-described embodiment, the present invention is not limited to this.
Other terminal devices such as word processors and personal computers can also be used.

[Effects of the Invention] According to the present invention, the number of characters in one line, which is the basis for calculating the number of lines displaying the remaining memory capacity, is made equal to the light margin setting value, so even if the light margin setting value changes,
Since the number of rows displaying the remaining memory capacity matches the actual remaining capacity, the operator can obtain accurate remaining memory capacity information.
