Abstract

PURPOSE:To rapidly perform display, by a method wherein a character code showing the synthetic character of a basic character and an overlap character is stored when both characters are continuously inputted to directly read the pattern data of the synthetic character. CONSTITUTION:When a basic character and an overlap character are continuously inputted from an input means M1, an input data memory means M3 synthesizes both characters to convert the same to a character code showing a synthetic character and said code is stored in an input data memory means M2. In displaying the synthetic character, the pattern data of said synthetic character is directly read from a pattern data memory means M4 on the basis of said character code to be displayed on a display means M5. In printing the synthetic character, the basic character and overlap character constituting of the synthetic character are printed at the same position on recording paper in an overlapped state by a printing means M6. By this method, the synthetic character can be rapidly displayed using a video RAM for one image.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an information processing device that can display and print a plurality of characters input from a keyboard or the like as one composite character.

[Prior Art] Conventionally, in an information processing device, for example, r
If there is a composite character with a duplicate character ``°°'' added to the basic character raJ such as ``Stone'', by inputting each character sequentially from the keyboard, the composite character can be displayed on a CRT, etc. Some are configured so that they can be printed using a printer or the like.

In this type of device, when a basic character and a duplicate character are input successively, a character code is attached to each character, and a composite character is stored using these two character codes. In addition, to display a composite character, pattern data corresponding to the two character codes that make up the composite character may be read out from a character generator and combined, or the two character codes may be converted into a character code representing the composite character, and the resulting conversion may be performed. This is done by reading the pattern data of the composite character from the character generator using the character code created.

In some cases, the printed image is distorted on the display screen to display two characters divided into two columns, so that a composite character can be formed on the recording paper only during printing.

[Problem to be Solved by the Invention] The conventional device described above has good operability because when displaying or printing a composite character, the basic characters and duplicate characters that make up the composite character can be input directly from the keyboard etc. But the composite character is 2
Because the data is stored in individual character codes, the storage area is twice as large as normal, and as the number of composite characters increases, the amount of data that can be processed decreases.

In addition, when displaying a composite character, a video RAM that can store character codes for two screens is required to combine the pattern data of two characters, and vice versa. When converting and extracting pattern data of a composite character, it takes time to display and there is a problem that responsiveness deteriorates. Furthermore, if the composite characters are displayed in two columns, it is difficult to grasp the print image by looking at the screen, which impairs operability.

Therefore, when a composite character exists in data, the present invention not only allows the composite character to be displayed and printed, but also realizes the same screen display time as a normal character when displaying it, and also requires additional video RAM. The aim was to provide an information processing device without

[Means for Solving the Problems] That is, the present invention, which has been made to achieve the above object, includes an input means M1 for inputting a basic character and a duplicate character attached to the basic character, as illustrated in FIG.
The input character from the input means M1 is converted into a character code and stored in the input data storage means M2, and when a basic character and a duplicate character are continuously input from the input means M1, a composite character is created by combining both characters. input data storage means M for converting into a character code representing the character code and storing it in the input data storage means M2;
3, and pattern data storage means M4 in which pattern data of the basic character and composite character are stored in advance.
and a display means M5 for sequentially reading character codes from the input data storage means M2, extracting pattern data corresponding to the character codes from the pattern data storage means M4, and displaying the extracted pattern data on the display screen; Character codes are sequentially read out from the storage means M2, basic characters corresponding to the character codes are printed on recording paper, and if the read character code is a code representing a composite character, the basic characters and characters constituting the composite character are printed. The gist of the present invention is an information processing apparatus characterized by comprising a printing means M6 for printing duplicate characters in duplicate at the same position on recording paper.

[Operation] In the information processing apparatus of the present invention configured as described above, when a basic character and a duplicate character are continuously input from the input means M1, a character code representing a composite character made up of these two characters is input to the input data. It is stored in the storage means M2. The display of the composite character is performed by directly reading the pattern data of the composite character from the pattern data storage means M4 using the stored character code, and the printing of the composite character is performed by reading out the pattern data of the composite character directly from the pattern data storage means M4 using the stored character code. This is done by printing multiple times at the same location on the recording paper.

[Example code] Embodiments of the present invention will be described below with reference to the drawings.

First, FIG. 2 is a schematic configuration diagram showing the overall configuration of a document creation device according to an embodiment to which the present invention is applied.

As shown in the figure, the document creation device of this embodiment includes a keyboard 1 for inputting characters and editing instructions, a display device (CRT display) 3 for displaying characters and figures, a flexible disk drive 5 as an external recording device, It is comprised of a printer 7 that prints characters and figures using daisy-wheel type typefaces, and an electronic control unit 10 that is connected to these devices and controls the creation, display, and printing of documents.

The electronic control device 10 includes a well-known CPU II, ROM 12.
It is configured as a logic operation circuit centered around RAM14, etc.
A video RAM 15 that records character and graphic pattern data to be displayed on the RT display 3, a keyboard input board 16 that inputs key data from the keyboard 1, and a flexible disk that controls the flexible disk drive 5 to read and write data. It includes a drive controller b roller 18, a printer output boat 20 for outputting print data to the printer 7, and the like.

The RAM 14 is used as a text memory 14a as an input data storage means M2 for storing character information sequentially input from the keyboard 1, and for temporarily storing data for synthesizing input characters or editing a document. It is equipped with a work memory 14b and stores various data in a rewritable manner.

The ROM 12 also stores control programs and initial data for creating, displaying, printing documents, etc.
Pattern data necessary for displaying characters and symbols is stored.

On the other hand, the video RAM 15 has a so-called dual port RAM configuration, and has a CRT provided independently of the CPU 1.
The configuration is such that it can also be accessed by the controller 22. The CRT controller 22 controls the video RAM 1 at a period determined by the scanning frequency of the CRT display 3.
5 is repeatedly read out and displayed on the CRT display 3. Therefore, video RAM is
The data written to the predetermined area of l5 is immediately CR
It will be displayed on the T-display 3.

Next, the keyboard 1 is equipped with a character key 31 for inputting characters, various instruction keys 33 for commanding document editing 9 display, printing, etc., and a cursor key 35 for moving a cursor. When various keys are pressed, a preset key code is generated for each key. Therefore, the user can create a document by pressing the character key 31, and can also edit, display, print, etc. the document as needed.

The created document can also be temporarily recorded in the RAM 14 and then written to a flexible disk set in the flexible disk drive 5 via the flexible disk drive controller. The character key 31 includes basic characters (X characters) representing alphabets, numbers, spaces for one character, etc.
Basic character and dead symbol input corner keys are provided so that dead symbols (duplicate characters) attached to the basic characters can be input.

Next, FIG. 3 is a flowchart showing document data creation processing executed by the electronic control unit 10.

This process is executed when a document creation command is issued via the keyboard 1, and when the process starts, the SL first stores the display address and text memory that indicate the display position of characters on the display screen. Initialization processing is executed to set an initial value to the document data storage address representing the storage position of characters in the keyboard 14a, and the process moves to S2.
Wait for the key code to be entered. When a key code is input, it is determined in S3 whether or not the input code is a dead symbol code. If it is a dead symbol code, the process moves to S4 and the dead symbol storage area in the work memory 14b is stored. Store the input dead symbol code and
5, a dead symbol is displayed at the display address position on the CRT display 3. The display address is video RAM1
5 indicates the display position of the characters on the CRT display 3, and the above display is made by reading pattern data corresponding to the dead symbol code from the ROM 12 and storing it in the display address of the video RAM 15. It is done.

When the dead symbol is displayed in this way, the process moves to S6 and waits for a basic character code to be input from the keyboard 1. Then, when the basic character code is input, the process moves to 87, and the input basic character code and the dead symbol code stored in the work memory 14b in 84 are converted into a de and do symbol using a preset conversion table. and a basic character into a composite character code representing a composite character, and the process moves to S8. Then, in S8, the pattern data corresponding to the converted composite character code is read from the ROMI 2 and stored in the display address of the video RAM 15, so that the dead symbol is displayed on the display screen where it was displayed until now by the processing in S5. The composite character is displayed again, and the process moves to <99, where the converted composite character code is stored in the document data storage address of the text memory 14a.

Note that if a space code representing a space is input as the basic character code, even if a dead symbol and a space are combined, it will become a dead symbol, so the conversion process to the composite character code is not performed in S7 above, and the process of converting to a composite character code is not performed in S8. Even after the process is executed, the dead symbol remains on the display screen. Also S
9, the dead symbol code is stored in the text memory 14 as it is.
It is stored in a.

On the other hand, if it is determined in S3 that the input code is not a dead symbol code, the process moves to S10, and it is determined whether the input code is a basic character code.

Then, if it is determined that it is the basic character code, S11
After moving to and storing the input basic character code in the document data storage address of the text memory 14a,
Proceeding to S12, pattern data corresponding to the basic character code is read from the ROM 12, and the basic character is displayed at the display address position on the CRT display 3.

When a composite character or a basic character is displayed by inputting the character key 31 in this way, the process moves to S13, where the display address and the document data storage address are counted up, and the process moves to S2 again.

Next, if a negative determination is made in 83 and SIO, that is, if a key other than character key 31 is input, S
14, it is determined whether the input code is an end code. If the input code is an end code, the end code is input to the document data storage address of the text memory 14a in step 515 and the process ends; otherwise, the step goes to step 516 and editing corresponding to the input code is performed. The process is executed and the process moves to S2 again.

Next, FIG. 4 is a flowchart showing a created document display process executed by the electronic control unit 10.

This process is executed when the user issues a command to display a created document stored in the text memory 14a through a keyboard operation. When the process starts, first, in S20, the document to be displayed is The start address of the data is set as the display data storage address, and the process moves to 921 to initialize the display address. And the following S22
Now, read the document data (code) stored in the display data storage address of the text memory 14a, and
23, it is determined whether the read code is a character code. If this 523 is affirmatively determined,
The process moves to S24, and the pattern data corresponding to the read code is read out from the ROMII and displayed at the display address position of the CRT display 3, and the process moves to S25.

Then, in 825, the display address and the display data storage address are counted up, and the process returns to S22.

Next, in 523, if it is determined that the read code from the text memory 14a is not a character code, the process moves to 826,
It is determined whether the read code is an end code. If the read code is an exit code, there is no more data to display, so the process ends.
Otherwise, if it is a control code such as line break or centering, the process moves to S27 to display the document data corresponding to the control code, and then moves to S22 again.

Next, FIG. 5 is a flowchart showing the created document printing process executed by the electronic control unit 110.

This process is executed when the user issues a command to print a created document stored in the text memory 14a through a keyboard operation. The start address of is set as the print data storage address, and the process moves to 531. In S31, the document data (code) to be cut stored in the print data storage address of the text memory 14a is read out, and the process proceeds to S32, where it is determined whether the read code is a composite character code. If an affirmative determination is made in S32, the process proceeds to S33, where the read composite character code is converted into a dead symbol code and a basic character code using a preset conversion table. And the following S3
In step 4, the converted dead symbol codes and basic character codes are sequentially outputted to the printer, and the dead symbols and basic characters are printed overlappingly on the recording paper set in the printer.

On the other hand, if it is determined in S32 that the read code is not a composite character code, the process moves to 935, and it is determined whether the read code is a character code (that is, whether it is a basic character code or a dead symbol code). . If the read code is a character code, the process moves to 536, where the read character code is output to the printer and a basic character or dead symbol is printed on the recording paper.

After the characters are printed in step 834 or S36, the process moves to step S37, where it is determined whether the print position on the recording paper has reached a preset write margin. If the light margin has been reached, the process moves to 53B, where a paper feed signal is output to the printer to feed the recording paper by one line, and the process moves to the following S39, where a head movement signal is output to the printer. Then, the print head is moved to the left margin, and the process returns to S31. Conversely, if it is determined in 937 that the print position has not reached the write margin,
The process moves to S40, where a print head movement signal is output to the printer to move the print head to the right by an amount corresponding to a preset character pitch, and the process moves again to S31.

Next, if it is determined in 935 that the read code is not a character code, the process moves to S41 and it is determined whether the read code is an end code. If the readout code is an end code, there is no more data to be printed, so the process ends; otherwise (in other words, if it is some kind of control code), the process moves to S42 and the process corresponds to the readout code. The printer drive process is executed, the printing position, etc. is changed, and the process returns to S31.

As explained above, in the document creation device of this embodiment, when creating a document, the keyboard 1 is used to input a dead symbol (for example, "r").
) is input, the basic character code representing a basic character (for example, "a") is input, and the input basic character code and dead symbol code are combined into a composite character. The code is converted into a composite character code representing (for example, "t") and stored in the text memory 14a. Therefore, it is not necessary to store two character codes (i.e., a basic character code and a dead symbol code) in the text memory to store composite characters as in the past, and the storage area of the text memory is required to store composite characters. will not be narrowed down. In addition, when displaying composite characters in a created document again, the composite character code in the text memory can be read and the pattern data can be directly displayed using that composite character code. There is no need to perform conversion or pattern composition, and composite characters can be quickly displayed using one screen's worth of video RAM. In addition, when printing composite characters, the composite character code is reconverted into a dead symbol code and a basic character code and output to the printer, and the characters corresponding to each character are printed overlappingly on the recording paper. Therefore, there is no need to prepare types for composite characters in order to print composite characters, and conventional printers can be used as they are to print composite characters.

[Effects of the Invention] As detailed above, according to the information processing device of the present invention, by continuously inputting a basic character and a duplicate character, it is possible not only to display and print a composite character of both characters, but also to display and print a composite character of both characters. When displaying a composite character, pattern data is extracted by combining the two character codes that make up the composite character, or pattern data is extracted for each two character codes and combined on the display screen. There is no need to do this, and the composite character can be quickly displayed using a single-screen video RAM.
