Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to a method for moving a cursor displayed on a display screen in a document processing device.

(Conventional Example) Conventionally, in document processing devices equipped with display devices such as electronic typewriters and word processors, it is possible to make 1m corrections to a document on the screen of the display device, and the cursor displayed on the screen can be The user moves to the desired document location and performs operations such as insertion, deletion, and movement. for that,
It is equipped with cursor movement keys for moving the cursor in various directions. For example, for horizontal cursor movement, a cursor forward key is used to move the cursor to the right for each character iσ, and a cursor back key is used to move the cursor to the left for each character. When moving the cursor position for a long time, use the repeat function that moves the cursor continuously by holding down the cursor forward key or cursor back key, or move the cursor word by word or sentence by sentence. It is common to use separate cursor movement keys to

However, even if you move the cursor using the conventional repeat function, there is a drawback that it takes a lot of time to move the cursor to the desired document position. Providing a cursor movement key that moves every time not only complicates key operations but also makes the keyboard device expensive.

(Objective) The present invention was made in view of the above drawbacks, and an object of the present invention is to provide a cursor movement method that can speed up cursor movement without increasing the number of cursor movement keys.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings. Note that the cursor movement method of the present invention is applicable not only to horizontal cursor movement but also to vertical cursor movement; however, in the following, the cursor movement method in the horizontal direction on a typewriter equipped with a one-line display will be described. I will explain about it.

FIG. 1 shows an example of the system configuration of an electronic typewriter according to the present invention. Here, 1 is a keyboard device, and as shown in FIG. It has a key 12 and a cursor back key 13. Reference numeral 2 denotes a display device that displays one line of a finite number of character strings and also displays one cursor that indicates the position for correction or editing. Reference numeral 3 denotes a storage device ♂l that stores documents input from the keyboard device 1 and stores character string data displayed on the display device 2.

4 is a control device realized by a microprocessor, and includes a keyboard control section 41. It is composed of three parts: a display control section 42 and a storage control section 43. The keyboard control unit 41 reads the data of the pressed key, performs processing according to the data, and issues instructions to other control units. In addition, it detects whether a repeatable key is continuously pressed and repeats the process of the pressed key.Continuously pressed keys can be detected by using a double action key that generates an electrical signal, or by using a method that generates an electrical signal for a certain period of time. It is possible to detect by reading the interval key, but any method may be used.1 The display control unit 42 controls the one-line display block 2 having a finite number of display cells. Display and scroll columns, display and move the cursor, etc. The storage control unit 43 is responsible for writing and reading data into and from the storage device 3 .

As an example, the movement of the cursor when the cursor forward key is pressed will now be explained based on the flowchart shown in FIG.

First, the cursor forward key 12 of the keyboard device l
When the keyboard control unit 41 recognizes the press key, an instruction is issued to the display control unit 42 to move the cursor one character rIt to the right (Sl). Furthermore, cursor forward key 12
When the cursor is pressed and repeat is detected (S2), the cursor number σ is moved to the right for each character position repeatedly. When this repetition is repeated a predetermined number of times, for example, 15 times (S3), the cursor movement thereafter is l71i11r! The cursor is moved to the right by a medium 4σ (S4), and the cursor is moved word by word until the cursor forward key 12 is stopped being pressed (
S5).

Figure 4 shows "Cursor, forward Key"
moves cursorto tl+e right
” is displayed on the display device 2 and the cursor 21 is positioned at the character “Coo”, and the cursor forward key 12 is continuously pressed. The cursor 21 is 15 from ■ to O.
When moving the cursor, the cursor moves to the right every character position, but when moving the cursor 16 times [J and above (O2O9...), the cursor moves to the right every word.

Although the explanation has been given using the 3-in display as an example, a CR7 display may also be used.

Further, in the above embodiment, only the movement of the cursor in the horizontal direction has been described, but the present invention can also be applied to movement of the cursor in the vertical direction.

(Effect) As explained above, according to the present invention, the cursor movement key for each unit can be pressed several times without providing a cursor movement key with a special movement width other than the cursor movement key for each unit. This has the advantage that the cursor can be quickly moved to the desired position by pressing the button or pressing the button repeatedly, and the number of operation keys can be reduced and the operation can be simplified accordingly.
