[Cursor display processing (FIGS. 5 to 10)] The cursor display processing will be explained below with reference to the flowcharts shown in FIGS. 5 to 8 and the cursor display examples shown in FIGS. 9 to 10. In particular, the cursor display process executed when (1) a character size change instruction, (2) a cursor movement instruction, (3) a character cancel instruction, and (4) a character delete instruction are given will be described. Further, as shown in FIG. 9(A), it is assumed that text is input to the LCD 6 in a font size of 36 points. Here, 61 in FIG. 9(A) is a cursor indicating the character size of 36 points. Unless you instruct to change the font size,
Characters that are keyed in continue to be entered at a size of 36 points.

FIG. 5 is a schematic flowchart of cursor display processing.

First, in step S5, key input is accepted. Next, in step S10, it is checked whether the received key input is an instruction to change the font size. Here, if it is determined that the key input is an instruction to change the font size, the process advances to step S20, and font size changing processing is executed. In this embodiment, it is assumed that the font size change instruction is issued by pressing the MODE key 229 and the numeric key "2" at the same time. On the other hand, if the key input is not an instruction to change the font size, the process proceeds to step S3.
Go to 0.

[0023] From now on, processing corresponding to the above four instructions will be explained.

(1) Character size change processing step S20
In the font size change process, first, as shown in FIG. 9(B)
A character size setting screen 62 as shown in FIG. 1 is displayed overlaid on the document editing screen of the LCD 6. In the case of this embodiment, the font size setting screen 62 has 9 points (
“9point (Small)”), 12 points (
12 points (Standard)”), 18 points (“18 points (Medium)”), 24
Point (“24point(Large)”), 36
Points (“36 points (Largest)”),
Width expansion (“Expanded”) and width reduction (“Expanded”)
“Condensed”) are displayed. A desired character size is selected by inputting one of the numerical keys 1 to 7 corresponding to each size and pressing the return key 230. Here, the currently set size of 36 points is displayed in bold, and items that cannot be selected are displayed in italics. In FIG. 9B, the character size of 36 points is the maximum character size, and since further width expansion is impossible, width expansion (“Expanded”) is regarded as an item that cannot be selected. Furthermore, a style box 63 is displayed on the display screen, which shows information on the currently set character font, size, and style.

After the character size setting screen 62 is displayed, the user of the device selects a desired character size, and information on the selected character size is stored in the input character information area 112 at the cursor position. After that, the process proceeds to step S9.
Go to 0.

In step S90, the cursor position is set to the display position stored in the display position information 125 of the display character information 120 in the cursor line display character string information 111 that corresponds to the cursor position information 114 in the cursor line display character string information. The cursor shape is displayed on the LCD according to the input character information 112.
Display on 6. For example, if a 12 point font size is selected from the font size setting screen 62,
As shown in C), a cursor 64 having a shape corresponding to 12 points is displayed. For subsequent character input, as shown in Figure 9(D), the character size is 12 points.
The information will be displayed on CD6.

(2) Cursor movement instruction At step S30, it is checked whether the key input is a cursor movement instruction. Here, if it is determined that the key input is a cursor movement instruction, the process proceeds to step S4.
0 and performs cursor movement processing, and if the key input is not a cursor movement instruction, the process proceeds to step S50. In this embodiment, the cursor movement key 21 on the keyboard 1
It is assumed that an instruction to move the cursor has been made by any one of the inputs from 4 to 220.

Here, a sentence as shown in FIG. 10(E) is created on the LCD 6, and the cursor 65 is displayed in a 12-point shape to indicate the position of the last "t" of the 12-point character string "12point". The following processing will be explained assuming that it is displayed.

In the flowchart of FIG. 6, in step S41, it is determined whether the line is changed depending on the cursor movement destination. Here, the cursor line is not changed by moving the cursor (cursor movement key 220R or 2
If 20L is pressed, the cursor line will not change)
If it is determined that this is the case, the process proceeds to step S43. On the other hand, when the cursor is moved, the cursor line is changed (for example, the cursor movement key 220U is
Alternatively, if it is determined that 220D is pressed and the cursor line is changed if it is not the start line or the last line of the sentence, the process proceeds to step S42.

In step S42, new cursor line display character string information 111 to which the cursor is to be moved is created, and the process advances to step S43.

In step S43, the corresponding display character information 120 in the cursor line display character string information 111 is searched in accordance with the input cursor movement key. For example, if the cursor movement key 220R is input in step S5, "" displayed at 36 points in FIG.
The display character information 120 indicating the leftmost character "3" of "36point" is searched for. In step S44, the position of the display character information 120 searched in step S43 is set to the cursor position information 114 in the cursor line display character string information. Furthermore, in step S45, the font 1 of the display character information 120 indicated by the cursor position information 114 is stored.
22, size 123, and style 124 are stored in the input character information 112 at the cursor position. After that, the process proceeds to step S90.

In step S90, as already explained, a cursor shape according to the input character information 112 at the cursor position is displayed on the LCD 6. For example, when the cursor movement key 220R is pressed in the state shown in FIG. 10(E), the cursor 66 is displayed in a 36-point shape as shown in FIG. 10(F).

(3) Character Cancel Instruction Now, in step S50, it is checked whether the key input is a character cancel instruction. Here, if it is determined that the key input is a character cancel instruction, the process proceeds to step 60, and if it is determined that the key input is not a character cancel instruction, the process proceeds to step S70. In this embodiment, it is assumed that a character cancellation instruction is issued by inputting the cancel key 231 on the keyboard 1.

Here, a sentence as shown in FIG. 10(F) is created on the LCD 6, and the cursor 66 is displayed in a 36-point shape, indicating the position of the first "3" of the 36-point character string "36point". The 12 point character string (“12 point
”) will be explained below.

In the flowchart of FIG. 7, in step S61, the displayed character string information 111 in the cursor line is searched for the displayed character information 120 to be deleted. Here, 1
The 2-point character "t" is the corresponding display character.

In step S62, the font 122, size 123, and style 124 information of the display character information 120 retrieved in step S61 is stored in the input character information 112 at the cursor position. Here, the font size is 12
Information on the character size of the point is stored in the input character information 112 at the cursor position.

In step S63, the character to be deleted is deleted from the text information storage area 110, and in step S64,
After the cursor line display string information 111 after character deletion is recreated, the canceled cursor line is displayed according to the display character string information 111 in step S65. This is shown in Figure 10.
(G) The cursor 67 is not displayed.

Further, in step S66, the display character information 120 corresponding to "3" indicated by the cursor is searched from within the new cursor line display character string information 111, and the process proceeds to step S6.
7, the display character information 12 retrieved in step S66
The position of 0 is stored in the cursor position information 114 in the cursor line display character string information. After that, the process proceeds to step S90.

In step S90, as already explained, the cursor shape is displayed on the LCD 6 in accordance with the input character information 112 at the cursor position. Here, the cursor 67 is displayed in a 12-point shape as shown in FIG. 10(G).

(4) Character Delete Instruction Now, in step S70, it is checked whether the key input is a character delete instruction. Here, if it is determined that the key input is a character deletion instruction, the process proceeds to step 80.
If it is determined that the character is not deleted, the process ends. In this embodiment, CODE on keyboard 1
It is assumed that a character deletion instruction has been issued by pressing the key 228 and the cancel key 231 at the same time.

Here, the screen shown in FIG. 10(G) is displayed on the LCD 6, and the cursor 67 is displayed in a 12-point shape, and the character at the cursor position (the leftmost "3" of the 36-point character "36point") is displayed. ) is deleted.

In the flowchart of FIG. 8, in step S81, the cursor line display character string information 111 corresponding to the cursor position information 114 in the cursor line display character string information is
Display character information 120 in font 122, size 12
3. Store each information of the style 124 in the input character information 112 at the cursor position. Here, information on the left end "3" of the deletion target character shown in FIG.

Next, in steps S82 to S84, the same processing as in steps S63 to S65 described above is executed to display the cursor line after character deletion. This is the state in which the cursor 68 is not displayed in FIG. 10(H). Furthermore, in step S85, the display character information 120 of the character "6", which will be the new cursor position after character "3" has been deleted, is searched from the new cursor line display character string information 111. and,
In step S86, the same processing as in step S67 is executed. After that, the process proceeds to step S90.

In step S90, as already explained, a cursor shape according to the input character information 112 at the cursor position is displayed on the LCD 6. Here, the cursor 68 is displayed in a 36-point shape as shown in FIG. 10(H).

Therefore, according to this embodiment, according to (1) a character size change instruction, (2) a cursor movement instruction, (3) a character cancel instruction, and (4) a character delete instruction,
The shape of the cursor can be changed and displayed on the LCD in consideration of the currently displayed cursor shape and cursor position.

In this embodiment, only the cursor size change display processing according to the font size change has been explained.
The present invention is not limited to this, and for example, FIG.
As shown in 1, it is possible to display cursor shapes that match changes in character styles such as underlined characters, boldface characters, italicized characters, and outline characters, and to change the character font, superscript, subscript, and It is also possible to change the cursor shape and display it depending on the difference in shading information, etc.

In addition, in this embodiment, cursor movement processing and
Although the process of changing and displaying the cursor shape when only a change in character size occurs due to character cancel processing/delete processing has been described, the present invention is not limited to this. For example, even when a change in character font, style, etc. occurs, the cursor shape can be changed and displayed in accordance with the change in information.

Furthermore, the present invention is not limited to the explanation of the above embodiments, but the present invention is applicable when input character information at the cursor position is changed while editing a document using a word processor, for example, word deletion, line deletion, range deletion, etc. It is also possible to handle specified deletion, etc.
