Abstract

PURPOSE:To surely move a cursor to an intended position by selecting and executing a line crossing mode in which the cursor in the line end crosses the line and moves continuously, and a line end stop mode in which the cursor movement stops in the line end. CONSTITUTION:When the left cursor key is operated continuously at the time point when a cursor is positioned in a position P3 in a display screen 15 of an indicator 15, after it is decided to be the left cursor key, it is decided that the start position is not the line head, and the cursor is moved in the left direc tion by a one-character portion. Thereafter, the processing is executed repeatedly until it is decided that the cursor reaches a position P2, the cursor is moved continuously by a key repeat, and at the time point when the cursor reaches the position P2, the movement of the cursor is stopped. When the left cursor key is operated newly at the time point when the cursor is in this position P2, after it is decided to be the left cursor key, it is decided that the start position of operation is the line head, and the cursor crosses the line and is moved to the position P3 of the line end of the previous line. In such a way, the cursor movement can be executed surely.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a document creation device characterized by a cursor position control method.

(Prior art) In conventional Japanese word processors, for example, when the cursor is positioned at the end of a line and a cursor key operation is used to instruct the cursor to move further to the right, the cursor is not moved from the end of the line. , there was one that moved the cursor to the beginning of the next line.

Compared to the method that does not move the cursor from the end of the line, the method that moves the cursor to the beginning of the next line allows the cursor to move in line with the flow of the sentence, making document input more efficient. It had this advantage.

(Problem to be Solved by the Invention) However, with the above-mentioned device that moves the cursor to the beginning of the next line, if you release the cursor key that you are continuously operating at the wrong time when you want to position the cursor at the end of the line, the cursor will move to the beginning position of the next line. moves to the opposite end of the adjacent row,
You have to operate the cursor keys in the opposite direction again. Also, especially if the number of characters per line of the document is set to 1 on the display section.
If there are more characters than the number of characters in a line, the display section cannot display the entire line direction at once, so if the cursor key is incorrectly operated, the cursor moves to the opposite end of the adjacent line, and the entire display screen is displayed. is scrolled, and the desired cursor stop position disappears from the display screen, resulting in a problem that document input cannot be performed smoothly.

The present invention has been made in view of the above-mentioned circumstances, and its purpose is to provide a document creation device with high operability by suppressing unnecessary movement of the cursor due to erroneous operation of the cursor keys. .

[Structure of the Invention (Means and Effects for Solving the Problems) The present invention enables the cursor at the end of the line to move past the line by determining whether or not the cursor was at the line end position when the cursor key operation started. This allows you to select between a line-crossing mode in which the cursor moves continuously across lines, and a line-end stop mode in which the cursor stops moving at the end of the line, thereby avoiding unintentional cursor crossing and ensuring that the cursor is at the intended position. You will be able to move it to

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

FIG. 1 shows its basic circuit configuration, where IO is a microprocessor (CPU) and 11 is a RAM accessed by the microprocessor 10.

12 is the same ROM.

A microprocessor (hereinafter referred to as CPU) 10 controls the entire device, and controls the RAM II and ROM described above.
12 and starts a program according to input instructions to execute document creation processing, external character creation processing, key manual control processing as shown in FIG. 2 above, and the like. RAMII
consists of areas for storing various control information such as a document area, line image area (print buffer), external character registration area, word/phrase registration area, and a cursor position register for storing the cursor position on the document display screen. ROM12 is CPUl
A program area 12a stores input processing programs including a program for determining the operation of 0 and a cursor control routine associated with manual keystrokes as shown in FIG. 2, and a character pattern area 12b1 for storing display or print character patterns. Dictionary area 1 where various dictionaries for converting readings input in kana or romaji to kanji are registered.
2c etc.

Also, 13 is the keyboard (KB), 15 is the display, 18
is a floppy disk device (FDD), and 20 is a printer (PRT). The keyboard (KB) 13 uses a keyboard interface (KB) to input information necessary for document creation, etc.
The data is input to the CPU 10 via the KB-IF) 14. In addition to character keys, numeric keys, cursor keys, etc., this keyboard 13 includes a half-width specification key that switches the cursor range from full-width to half-width, and a "hiragana" shift key and a "katakana" shift key that switches the cursor range from half-width to full-width. Various function keys are provided including a "kanji" shift key and the like. The display 15 is comprised of, for example, a liquid crystal display device that displays 20 lines and 40 characters. The display controller (display-○NT) 1B controls the display of the display 15 using the display RAM 17 under the control of the CPU10. The floppy disk device 18 connects to the CPU10 via a disk interface (FDD-IF) 19.
Under the control of the computer, the created document is saved and external characters, second level characters, etc. are stored. The printer 20 communicates with C through a printer interface (PRT-IF) 21.
Under the control of PUl0, a created document or character information read into the main body from the floppy disk device 18 is printed.

Next, the operation of the above embodiment will be explained.

FIG. 2 shows a routine executed by the CPU 10 when the cursor keys in the left and right directions are operated on the keyboard 13. At the beginning of the process, the cursor key operated in the left direction is as shown in step Sl. Determine whether the left cursor key specifies movement.

If it is the left cursor key, then in step S2 it is determined whether the cursor was positioned at the beginning of the line when the operation of the left cursor key was started.

If it is determined that it is not at the beginning of the line, then step S
Proceed to step 8 and move the cursor one character toward the beginning of the specified line. Thereafter, in step S4, it is determined whether the position to which the cursor has moved has reached the beginning of the line.

If the beginning of the line has not been reached, continue with step S.
Proceeding to step 5, it is determined whether the same cursor key is still being operated continuously. If the key has not been operated, this process ends, but if the key has been operated, the process from step S3 is repeated again using the key repeat operation to continue moving the cursor.

In addition, if it is determined that the position of the cursor has reached the beginning of the line in step S4, the process ends at this point and the cursor is moved to that position, regardless of whether the cursor keys are still being operated continuously. Stop at the beginning of the line.

If it is determined in step S2 that the cursor was located at the beginning of the line when the cursor key operation started, the process proceeds to step S6, where the cursor is moved across the line to the end of the previous line, and then step S5 is performed. This is all about key repeat processing.

Furthermore, if it is determined that the operated cursor key is not the left cursor key in step Sl, it means that the operated cursor key is the right cursor key. Determine whether the cursor is at the end of the line.

If it is determined that it is not located at the end of the line, then step S
Go to step 8 and move the cursor one character toward the end of the specified line. Thereafter, in step S9, it is determined whether the position to which the cursor has moved has reached the end of the line.

If the end of the line has not been reached, continue with step S
Proceeding to IO, it is determined whether the same cursor key is still being operated continuously. If the key has not been operated, this process ends, but if the key has been operated, the process from step S8 is repeated again using the key repeat operation to continue moving the cursor.

Additionally, if it is determined in step S9 that the cursor has moved to the end of the line, the process ends at this point and the cursor is moved to the end of the line, regardless of whether the cursor keys are still being operated continuously. Stop at the end of the line.

If it is determined in the above step S7 that the cursor was located at the end of the line when the cursor key operation was started, the process proceeds to step Sll and moves the cursor across the line to the beginning of the next line, and then returns to step SIO. This is all about key repeat processing.

By performing the processing operations described above, the cursor control becomes as shown in FIG. FIG. 3 shows the number of lines on one page and the number of characters on one line on the front screen 15a of the display 15 (
15b) illustrates the movement of the cursor while editing a document 31 that is sufficiently large compared to the document 31 shown in FIG. For example, display 15
If the left cursor key is operated continuously when the cursor is located at the position indicated by P on the display screen 15, the operation is started in step S2 after it is determined that the left cursor key is the left cursor key in step S1. It is determined that the position is not at the beginning of the line, and the cursor is moved one character sentence to the left in step S3. Then, in step S4, the cursor moves to P2 at the beginning of the line.
The processes of steps S3 to S5 are repeatedly executed until it is determined that the cursor has reached the position , and the cursor continues to be moved by key repeat. Thereafter, when the cursor reaches the position of the beginning of the line P2, this is determined in step S4, and the movement of the cursor is stopped.

When the left cursor key is operated anew when the cursor is at the position of the beginning of the line P2, it is determined in step S1 that it is the left cursor key, and then in step S2 it is determined that the operation start position is the beginning of the line, and step In S6, the cursor is moved across the line to position P3 at the end of the previous line. In this case, since the position P3 is outside the range of the display screen 15a, the display screen is newly changed to the range indicated by 15b,
The cursor is moved and displayed at the position of P3 on this screen 15b.

In this way, when the cursor key is operated to the left or right, it is determined whether the cursor is located at the end of the specified direction at the start of the operation, and if it is not located, the cursor is positioned at the end of the specified direction. The cursor continues to be moved by key repeat until the end is reached, and when the end is reached, continuous key operations are disabled and the cursor is positioned at the end. After that, when a new cursor key is operated in the same direction, the cursor is moved across the line according to the flow of the sentence.

[Effects of the Invention] As detailed above, according to the present invention, the cursor at the end of a line can be continuously moved across lines by determining whether or not the cursor was located at the end of the line when the cursor key operation was started. We have made it possible to select between the line crossing mode, where the cursor moves at the end of the line, and the line end stop mode, where the cursor movement stops at the line end.
To provide a highly operable document creation device that can avoid unintentional movement of the cursor and reliably move the cursor to an intended position.
