JPS61122734A - Repeated input system of character - Google Patents

Abstract

PURPOSE:To execute the repeated input of the same 'Kanji' (Chinese character) or the like easily by forming a repeat key for indicating the repeat of a character displayed immediately before a cursor. CONSTITUTION:Data inputted from an input device 10 are analyzed and worked by a CPU 20 and written in a document buffer 41 of a memory (RAM) 40 on the basis of a code format. Simultaneously with said processing, the CPU 20 reads out the contents on the screen of a display device 50 and supplies and displays the read-out contents on the display device 50. When a repeat key is depressed, the CPU 20 reads out a character in the document buffer 41 which is to be displayed immediately before the cursor and supplies the character to the display device 50 so as to be inserted into a position immediately before the cursor. The CPU 20 executes similar processing also for a character string in the document processing buffer 41.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a method for continuously and repeatedly inputting the same character in a document creation device.

[Background of the invention]

2. Description of the Related Art In a document creation device, when inputting the same character continuously, 1 the character key is usually pressed repeatedly. But 1. If you try to input the same kanji in succession using this method, the operation becomes extremely cumbersome because it involves conversion of kana to kanji. This also applies to the case where the same character is inserted consecutively after any character that has already been input. Furthermore, in conventional document creation devices equipped with a repeat key, when repeating the previous function operation, the press of the repeat key is used instead, and no consideration is given to inputting the same character continuously. .

[Purpose of the invention]

An object of the present invention is to realize repeated input of the character WX, continuous insertion of previously input characters, repeated input of characters selected from a menu, etc., by fffll key operations.

[Summary of the invention]

The present invention provides a repeat key that instructs to repeat the character immediately before the cursor, and when the repeat key is pressed, the character immediately before the cursor is repeatedly inserted immediately before the cursor while the repeat key is pressed. It is characterized by

[Embodiments of the invention]

FIG. 1 is an overall block diagram of a document creation device to which the present invention is applied. In FIG. 1, an input device 10 includes a keyboard on which various function keys, character keys, etc. are arranged, and among the keys, there is a repeat key that relates to the present invention. The data input from the input device IO is centrally processed! The data is analyzed and processed in step 20 and written in code form to a document buffer 41 in a memory (RAM) 40. In parallel, the central processing unit 20 displays the contents of the document buffer 41 on the display device i! The i output is sequentially supplied to the 1 display device 150 for display in 50 screen display units.

Input device! ! When the 10 repeat key is pressed, the central processing unit! 20 reads the character immediately before the cursor in the document buffer 41 and supplies it to the 1 display liquid aSO to insert and display it immediately before the cursor, and also performs the same processing on the character string in the document buffer 41.

The program necessary for processing the central processing bag W20 is stored in the memory (
ROM) 30, one of which is a repeat input program 31 according to the present invention. The repeat input program 31 is activated by pressing the repeat key, reads the character immediately before the cursor from the document buffer 41, and displays it on the display device! 50, and while the repeat key continues to be pressed, that character is repeatedly inserted and displayed.

FIG. 2 shows a processing flow diagram according to the present invention.

First, when the power is turned on, the loop state continues until there is key power (step 101), and when there is key power,
The key is determined (step 102). And Wi
If it is the source disconnection key, the process ends.

If a key other than the repeat key is manually operated, other processing continues (step 106). On the other hand, in the case of a repeat key, step 1 is used to determine whether there is a character immediately before the cursor.
03), if there are no characters, an error buzzer is sounded (step 107). When the repeat key is input and there is a character immediately before the cursor, the character immediately before the cursor is read from the one-document buffer 41, supplied to the display device 150, and inserted at the display position immediately before the cursor (step 104). Next, step 1 to determine whether the repeat key is pressed or not
05), while the repeat key continues to be pressed, the process of step 104 is repeated; during this time, the document buffer 41 is 0.
For the character string, shift the read character forward one character at a time, write the same character immediately after the read character, and repeat this while the repeat key is pressed.
When the repeat key is released, repeat processing ends.
The key power is monitored in a loop until the next key power is available.

FIG. 3 shows an example of repeatedly inputting characters using the repeat key. In Figure 3, "-" indicates the cursor position. If you keep pressing the repeat key in the state of 3 @ (a), the character "K" immediately before the cursor will be input continuously, and the first display screen will be as shown in Figure 3. Figure 3 (2).
As shown in Fig. 3), if you move the cursor to the character "ka" using the left cursor key and press and hold the repeat key again, the character "o" immediately before the cursor will be input continuously, and the 1 display screen will be displayed as shown in Fig. 3 (c). d) Figure 3 shows all hiragana characters, but the same is true for kanji.

〔Effect of the invention〕

According to the present invention, by simply pressing the repeat key, it is possible to input or insert any number of characters immediately before the cursor, so when repeatedly inputting the same kanji, etc., it is possible to input or insert the character immediately before the cursor. becomes very easy.
