Abstract

PURPOSE:To facilitate checking such as gathered characters at left/right end, line feed or inhibited processing at print by extracting a part of the beginning and end of one line of print information string and displaying it on a display device having a number of display digits smaller than the number of printed digits. CONSTITUTION:On line's content of a sentence to be printed, e.g., 80 characters, are extracted from a data memory 19 and stored in a buffer memory 21. Then left 18 characters are extracted from one line's content of data in the buffer memory 21 succeedingly and displayed from the left side of the display device and four symbols representing the middle part are displayed. Finally, right side 18 characters of one line's content data in the buffer memory 21 are extracted and displayed on the display device succeedingly. When the operation is repeated and the screen of the display device 9 is fully occupied, the key input is awaited and the next 20 lines are displayed. Since the first part and the end part of one line of the print information string are extracted and displayed corresponding to the beginning and end of one line of the display device 1 in this way, even if a display means with less number of display digits is used, the entire constitution of the sentence to be printed out is displayed effectively.

Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a display device having a smaller number of display digits than the number of print digits of a printing device for printing text to be printed in a word processor or a personal computer having a text editing function. The present invention relates to a text display device that displays the text in its entirety.

[Technical Background of the Invention] As personal computers have become more widespread, various types of software have been developed, and many types of software have been developed, such as so-called word processors, which have a text editing function.

When printing a text edited with such a word processor using a printer, the text to be printed is displayed on a display device and the structure of the entire print format etc. is checked in advance before printing.

By the way, many personal computers use home television receivers as their display devices, but the number of characters that can be displayed per line on such display devices that also double as a television receiver is not very large. , for example, about 40 characters. However, printing devices, ie, printers, are generally capable of printing about 80 characters per line, and printers that print English text in particular are usually configured to print 60 to 80 characters per line. Therefore, when printing a text of 80 characters per line with a printer, check the final print format etc. by displaying the text on the above-mentioned TV receiver with a small number of display digits. When attempting to edit the text, there is a problem in that the entire text to be printed by the printer cannot be displayed as is.

Conventionally, in such cases, each character to be displayed is displayed as a dot, and the dots are used to display only the structure of the entire sentence. However, this method lacks specificity and cannot completely check, for example, the state of line breaks or prohibition processing, and if there is an irregularity in the overall structure of the sentence, this point display will tell you where to correct it. There are problems such as it is difficult to find out whether the

[Purpose of the Invention] This invention has been made in view of the above, and its purpose is to effectively display the entire structure of the text to be printed using a display means with a small number of display digits. An object of the present invention is to provide a text display device.

SUMMARY OF THE INVENTION 1 In order to achieve the above object, the present invention provides a text display device having a display means having a number of display digits per line smaller than the number of print digits per line that can be printed by the printing means.
As shown in FIG. 1, from the beginning of the one-line print information string printed by the printing means to the
a first display control means 1 for extracting printed information of a predetermined number of digits and displaying it at the beginning of a line on the display means; and a remainder obtained by subtracting the first predetermined number of digits from the number of display digits of the display means. a second display that extracts print information of a second predetermined number of digits less than or equal to the number of digits from the end of the print information string per line printed by the printing means and displays it at the end of the line on the display means; The gist is that the control means 3 is provided.

[Effects of the Invention] According to the present invention, a part of the beginning and a part of the end of one line of printed information string are extracted and displayed corresponding to the beginning and end of one line on the display device. Even when a display means with a small number of display digits is used, the entire structure of the text to be printed can be effectively displayed. In this case, in particular, characters near the left and right ends of each line of the text to be printed, line breaks, irregularities, processing of prohibited characters, etc. are clearly displayed, so these can be completely checked and the editing process is facilitated. can be done efficiently.

[Example of idea] Hereinafter, the present invention will be explained in detail using the drawings.

FIG. 2 is a block diagram of a text display device according to an embodiment of the present invention. In the figure, 1 is a central processing unit (hereinafter abbreviated as CPU) consisting of a microprocessor, etc.
, 7 is a keyboard for inputting characters, numbers, control information, etc.; 9 is a display device such as a CRT display for displaying characters, numbers, etc. input from the keyboard 7; this display device H9 is an interface; It is connected to CPtJ5 via a certain display circuit 13. Reference numeral 11 denotes a printer for printing characters, numbers, etc. input from the keyboard 7, and this printer 11 is connected to the CPtJ5 via an output interface circuit 15. 17
inputs and processes characters, numbers, control information, etc. entered manually from the keyboard 7 and displays them on the display device 9, edits the text made up of the input characters, and sends the input text to the printer 11. A program memory 19 stores a program for displaying the entire structure of the text to be printed on the display device 9 and executing the processing shown in FIG. 3, which will be described later. A data memory 21 is used to store sentences input from the keyboard 7, and a buffer 7 memory is used to temporarily store various data. The printer 11 is a printer that can print 80 characters per line, and the display device 9 can print 40 characters per line.
This is a display device that can display 20 lines of characters.

In the device configured in this way, character information etc. input from the keyboard 7 are input processed under the control of the program in the program memory 17 and stored in the data memory 19.
While looking at the sentence of 40 characters per line displayed on the display bag M9, the user inputs the next sentence manually. Further, the text consisting of character information stored in the data memory 19 and displayed on the display device 9 is edited under the control of the program in the program memory 17 based on the control information input from the keyboard 7, and the text is edited as desired. The text is corrected and stored in the data memory 19 and displayed on the display device 9. After the desired text is completed through input processing and editing processing in this way, this completed text information is output to the printer 11 and printed.In this case, the text to be printed is In order to check the overall configuration in advance, the display device 9 has the same configuration as the printing configuration.
After checking the overall configuration by looking at this display, print.

However, in this case, if you want the printer 11 to print 80 characters per line, the display device 9 can only display up to 40 characters per line, so display the text in the same configuration as that printed by the printer 11 and check. Can not do it. Therefore, in this embodiment, of the characters printed in one line by the printer 11, the 18 characters from the left end and the 18 characters from the right end are extracted and displayed on the left and right sides of the display bag M9, respectively, and both A special symbol indicating the middle part, such as a "*" symbol, is displayed in the space corresponding to the four characters in between, so that the entire display is made with 40 characters per line, with the middle part omitted. By displaying in this way, the same 80 characters as in the printer 11 cannot be completely displayed, but at least characters near the left and right edges of the 80 characters to be printed, line breaks, irregularities, processing of prohibited characters, etc. can be displayed. So,
These can be completely checked and edited easily.

FIG. 3 is a flowchart showing a process for displaying the overall configuration for printing confirmation.

Hereinafter, the display process of the overall configuration for printing confirmation will be explained according to this process flow.

First, write the text to be printed from data memory 19 to 1.
Extract characters one by one, write to buffer memory 21, 1
This operation is repeated until 80 characters for a line are extracted and stored (steps 100 and 110).

When 80 characters for one line are stored in the buffer memory 21, 18 character information from the left end of this one line of character information is extracted, and these 18 character information are output to the display circuit 13 and displayed on the display device 9. The display is covered from the left end (step 120).

Next, display circuit 13 with four special symbols “*J” indicating the middle part.
and displayed on the display device 9 (step 13o).

Then, 18 character information from the right end of one line of character information in the buffer 7 memory 21 is extracted, output to the display circuit 13, and displayed on the display device 9 (step 140). In this way, in steps 120 to 140, of the 80 characters printed per line, the 18 characters from the left end and the 18 characters from the right end are displayed on the left and right sides of the display device 9, respectively, and in the middle between the two. , four special symbols "*" are displayed, and a total of 40 characters are displayed on one line of the display device 9.

This display operation per line is performed for 20 lines, and the display device 9
The characters to be printed are displayed until the screen is filled (step 150). When the display of 20 lines is completed, this display processing operation goes into a standby state with 20 lines displayed, and the same operation is repeated again by the key input to instruct the display of the next 20 lines. Similar processing is performed for 20 lines (step 160).

In the above embodiment, the number of characters per line printed by the printer 11 is 80, and the number of characters per line displayed on the display device 9 is 40, but the present invention is not limited to this.
