Abstract

PURPOSE:To access a desired character quickly, by correcting one-line components of inputted character information in a buffer. CONSTITUTION:One-line components of 1>= character information inputted latest from a keyboard 1, for example, ''NIHONGO NO DENSHI TAIPURAITA'' is stored temporarily in a buffer 6A and is accessed by a DMA circuit 7 and is displayed on a display 10 through a buffer switching circuit 8 and a display buffer 9. In case that this character information is corrected to ''NIHONGO DENSHI TAIPURAITA'', character ''NO'' in the buffer 6A is deleted when a delete key is opened after a cursor is moved to the position of ''NO''. Thus, ''NIHONGO DENSHI TAIPURAITA'' is displayed on the display 10.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for processing character information in a character processing device such as a word processor or an electronic typewriter.

Conventional Japanese language document processing devices (hereinafter referred to as word processors) require processing time when creating documents, and the operator's operation speed is faster (sometimes resulting in a decrease in operability. This is due to the fact that in order to identify the code and perform processing accordingly, the editing buffer consisting of information such as character strings and formats was sequentially checked, and the validity of the processing and execution of editing processing were performed throughout the editing buffer. 〇This invention was made in order to eliminate the above-mentioned drawbacks, and a buffer for storing input information is provided separately from the editing buffer, and when a small number of lines is to be corrected, the information stored in this separate buffer is corrected. The object of the present invention is to provide a method for processing character information in a word processor or the like, which enables quick correction work.

An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 1 denotes the keyboard of a Japanese word processor, which is equipped with character keys such as kana characters, alphanumeric characters i, etc., as well as kana-kanji conversion keys, correction keys, and other various function keys similar to those in known word processors. ing. The output signal of each key is individually coded.

2 is a code conversion circuit which discriminates the key code input from the keyboard 1 and converts it into a full key processing circuit, a sub-function processing circuit 3-2. Conversion y-action processing circuit 3-3. One of the function processing circuits 3-4 is selected. Here, the full key 7 processes hiragana, katakana, alphanumeric characters, symbols, line break codes, etc., and deletes subfunctions.

The conversion function for cursor movement etc. performs, for example, kana-bokuji conversion processing, and the function function performs registration, calling, etc. processing, respectively. For example, when a kana character is input, it passes through the full key processing circuit 3-1, activates the function processing command circuit 4, and stores the character in the primary buffer 6j via the buffer write processing circuit 5.

- The next buffer 6 is a first buffer 76A that stores character information for one line inputted in the first buffer 4, and a second buffer 6B that stores character information inputted manually for the first line of characters. and has.

The first buffer 6A is a memory direct access circuit (hereinafter referred to as DM).
It is called A circuit. ) Accessed by 7 Sane Sono Back 76
The character information read from A is applied to a display buffer 9 via a buffer switching circuit 8.

Reference numeral 10 denotes a display device of the word processor, which displays, for example, one line of characters.

Also, the second buffer 6B of the next buffer 6 is DM.
:The character information accessed by the A circuit 11 and read from the buffer 6B is applied to the editing buffer 12. This editing buffer 12 is accessed by a DMA circuit 13, and the read output is applied to the buffer switching circuit 8. The full key processing circuit 3-1 is connected to the character count processing circuit 14, and when the number of characters is 1,
Within the range where lines can be displayed, the buffer switching processing circuit 8 is switched to the primary buffer 6 side.The editing buffer 12 stores several pages worth of input character strings, red tabs, indents, and format information. The contents of this editing buffer 12 are converted by a known method into a form that can be appropriately displayed in a buffer for creating a display format (not shown).

In the above configuration, character information of less than one line most recently input from the keyboard 1, for example, "Japanese electronic typewriter" is temporarily stored in the first cross 16A, and the character information is transferred to the DMA circuit. 7, the signal is applied to the display device 10 via the buffer switching circuit 8 and the display buffer 9, and is displayed on the screen of the display device 10 as shown in FIG. 2, for example.

Here, the above text information [Japanese electronic typewriter]
Japanese Electronic Type 2 To correct itazu, move the cursor to the "no" position as shown in Figure 3, then press the delete key (
(not shown), the above character in buffer 6A “
"of" is deleted.

Then, as shown in FIG. The data is written to the buffer 12.

When the number of characters entered exceeds one line, the characters entered before the most recent one line are sent to the second buffer 6.
B, further transferred to the editing buffer 12 via the DMA circuit 11, and then displayed on the display device 10 via the DMA circuit 13% buffer switching circuit 8 and the display buffer 9. The processing to be performed includes, for example, right and left cursor movement, right and left cursor deletion, and cancellation processing.

As described above, according to the present invention, one line of input character information can be corrected in the buffer 6A, so that the desired character information can be corrected in the buffer 6A. The call can be made quickly and the operator's waiting time can be shortened. The above-mentioned example on the right has been explained for the case of processing one line, but for processing two or several lines. You can store the character information in the primary buffer and modify this.

Claims (1)

[Claims] (1) Character information input from a keyboard equipped with keys for inputting character information and commands used for character processing is displayed on the display device according to predetermined lines, while the input character information is stored in an editing buffer. In a method for processing character information in a character processing device, input character information is stored in a storage means provided separately from the editing buffer, and when corrections are made, the characters stored in the storage means are A method for processing character information in a character processing device, characterized in that the information is corrected.
