Abstract

PURPOSE:To enable an operator to continue an input operation regardless of the input mode by deciding whether a character is already stored at a store position an performing the automatic switching between an insertion mode and a superscription mode. CONSTITUTION:An input part 1 produces a key code corresponding to an input operation. An input processing part 2 converts the key code into a character code, a code of KANJI (Chinese character), etc. and stores it temporarily. A character store part 3 inserts a character string to a text on a memory or superscribes said string. A memory part 4 stores a subject text for input and editing, and a display part 5 displays a text which is under input and editing. A cursor control part 6 is made coincident and correspondent between the character at the displayed cursor position and the character at the cursor position on a text stored in a memory part 4. Then a store/unstore deciding part 7 decides whether the characters are already stored on a text which is going to be supplied. An insertion/superscription switching part 8 inserts the input mode or switches the input mode to a superscription mode, and the switching result is delivered to the part 3.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to input processing for a Japanese document processing device.

Conventional Structures and Problems There has been remarkable progress in Japanese document processing devices in recent years, with new models being announced by various companies every year. Generally, there are two methods for inputting a string into text: one is to insert the string in insert mode, and the other is to overwrite the string on the text. Depending on the model, some have the two methods described above, while others have only one method (often inserted), but both methods require the operator to input a character string by operating a key on the processing device. Must. This process is complicated for the operator, and an input method that allows input where desired is desired.

Leaving the characters that have not yet been entered when deleting is a necessary process, especially for beginners.
In the overwriting process, it is often seen that characters input later are erased.

Purpose of the Invention In view of the above-mentioned drawbacks, the present invention provides an input method that allows an operator to input without always having to consider the current input mode, and that prevents careless overwriting and erasing already input character strings. The present invention provides a document processing device that provides the following features.

Structure of the Invention The present invention is configured such that when inputting a character string to a document processing device, the input is performed in insert mode if characters are already stored in the memory location to be stored, and in overwrite mode otherwise. It is.

DESCRIPTION OF EMBODIMENTS FIG. 1 shows an embodiment of the present invention. 1 is an input section,
Generates a key code according to input operations.

2 is an input processing unit, which converts the key code output from the input unit 1 into alphanumeric characters, character codes such as hiragana, 9 shirugana, kanji, etc., and also serves as a buffer for temporarily storing character code strings. It can happen. 3 is a character storage unit, which stores the character string output from the input processing unit 2 as text (
insert or overwrite a document). Reference numeral 4 denotes a memory unit that stores text (document) to be input and edited. 5 is a display unit, which displays the text currently being input/edited on a display device. Reference numeral 6 denotes a cursor control unit, which matches the character displayed at the cursor position on the display unit 5 with the character at the cursor position on the text stored in the memory unit 4. Reference numeral 7 denotes a stored/unstored determination unit, which determines whether or not a character is already stored at a position on the text that is currently being input. Reference numeral 8 denotes an insert/overwrite switching unit which switches the input mode to insert mode or overwrite mode according to the judgment of storage/unpaid discriminator 7. This result is output to the character storage section 3, where insertion processing or overwriting processing is performed.

FIG. 2 is a schematic flowchart of the main parts of the invention. Once the characters are entered and stored on the text, step 2
At step 1, the cursor control unit 6 associates the display cursor with the text storage position on the memory 4. Step 2
In step 2, the character at the text storage position determined in step 21 is read out, and it is determined whether or not a character is already stored at this position. If characters have already been stored, insert processing in step 23 is performed, otherwise, overwrite processing in step 24 is performed.

In the above-mentioned processing, the judgment is made every time one character is stored, so after continuing the overwriting processing, when a character is already stored at a position, the insertion processing is automatically executed.

FIG. 3 is an example of overwriting processing. 31 is a character string that has already been input and stored within the text. 32 is an area in which no character string is stored as text, and a pseudo space is displayed on the display unit 5.

A cursor 33 indicates the current input position.

This position 34 is a position where no character is stored, so the character 36
When input, a character is written at position 34 on the text, and cursor 33 moves to the next character position 36.

FIG. 4 is an example of insertion processing. 37 is a character string that has already been input and stored within the text. The cursor 33 is moved to a character position 38 in the middle of this character string 37, and the character 36 is input. Then, the string after character position 38 will be shifted to the back,
The input character 36 is inserted into character position 38. The cursor 33 moves to the next character position 39.

FIG. 6 shows input processing when using the present invention.

Processes 51 and 52 execute overwriting processing. Processing 52
Since the cursor 33 indicates the position where the character is already stored, insert processing is performed in steps 53 and 54.

Note that in the above processing description, the processing is completed for each character. However, processing one character at a time increases the processing time, so it is necessary to process multiple character strings at once. To deal with this, both the number of input characters and the number of characters that can be overwritten may be counted at the start of processing, and the overwriting processing and insertion processing may be performed separately.

Effects of the Invention As described above, the present invention automatically selects insert mode and overwrite mode by determining whether or not characters are already stored in the position to be stored in the current text when inputting data to a document processing device. Switch. Therefore, the operator can continue inputting without being aware of the input mode, and previously inputted characters will not disappear unless deleted.

This reduces the input burden on the operator and has a great practical effect.

Claims (1)

[Claims] An input processing unit that inputs a character string from an input device, a character storage unit that stores the input character string in memory, and a cursor control unit that controls the correspondence between the input position on the memory and the cursor position on the display screen. It is equipped with an overwrite process that sequentially stores character strings in memory using a storage/non-storage determination unit that determines whether characters are already stored at the current input position in memory, and an overwrite process that sequentially stores character strings in memory. Insert that moves the column backwards and stores the input string in memory.
