Next, in step S2, the set character size reflection display flag indicating whether the cursor line is temporarily displayed reflecting the character size is turned off (bit value "0" is stored). Then
At step S3, key input is awaited. Here, if any key is input, the process proceeds to step S4,
Determine the key. Here, if it is determined that the key input is (1) a character input, the process proceeds to step S5.
The key input is (2) a key for executing the character size setting (for example, MODE key 229 and numeric key “3”).
If it is determined that the operation is performed, the process proceeds to step S6.
Proceed to. If it is determined that the key input is neither (3) a character input nor a character size setting execution key, the process proceeds to step S9. Hereinafter, the processes (1) to (3) will be described.

(1) Character input processing In step S5, a first display processing after character input is executed.
Thereafter, the process proceeds to step S11. If the power is not turned off, the process returns to step S3 to wait for the next key input. If the power is turned off in step S11, the process ends.

FIG. 10A shows the document information created by repeatedly executing the first display process in step S5.
6 is a display example displayed in FIG. In FIG. 10A, 61
Is a set line space amount indicator, 1/6
It is displayed in the unit of inch as one line. A cursor line position indicator 62 displays the cursor line position on the page in units of 1/6 inch as one line starting from the top margin position. For example, in FIG. 10A, "2" is displayed because the cursor line is at the second line from the beginning of the sentence. A page indicator 63 displays a page number. Numeral 64 denotes a cursor, which in the case of FIG. 10A has a character size of 12 points and indicates that character input is performed. The character size of 12 points is a size corresponding to 1/6 inch (one line).

The details of the first display process in step S5 will be described with reference to the flowchart of FIG.

First, in step S51, a cursor line display character string table 113 is created from the leading character information 122 in the display line information 121 in the display line information table 112 indicated by the cursor position information 117 in the display line information table. At this time, the position of the display character information 131 indicated by the cursor position in the cursor line display character string table is stored in the cursor position information 118 in the cursor line display character string table. In step S52, the character size 133 of each display character information 131 of the cursor line display character string table 113 is set.
Search for the largest character size from
21 is stored in the maximum character size 123.

In step S53, the set line space amount 115 and the maximum character size 12 of the cursor line are set.
3 is determined, and the display line position of the cursor line is determined according to the larger amount.

For example, in the case of the screen shown in FIG.
The set line space amount indicator 61 is "1", that is, 1/6 inch, and the maximum character size of the second line is 24.
In points, this is 2 rows, 2/6 inch. In this case, the line feed amount from the first line is determined according to the maximum character size (24 points) of the cursor line, and the cursor display line position is "3" from the top margin.

As shown in FIG. 10A,
When the set line space amount indicator 61 is "1", that is, 1/6 inch, and the maximum character size of the second line is 12 points (one line, 1/6 inch), the cursor display line position is "2" from the top margin. ".

In step S54, the contents of the cursor line display character string table 113 created in step S51 are displayed on the LCD 6 at the display line position determined in step S53. That is, in the case shown in FIG. 10D, the value displayed on the cursor line position indicator 62 is “3”, and FIG.
In the case shown in (A), the cursor line position indicator 62
Is "2". In step S55,
Cursor position information 11 in the cursor line display character string table
A cursor having a size according to the set character size 116 is displayed at the position of the display position 134 of the display character information 131 shown in FIG. 8, and the set character size reflection display flag 119 indicating the temporary display after the character size is set in step S56. “0” is stored (turned off), and the process ends.

(2) Character Size Setting Processing In step S6, for setting the character size, the screen of the LCD 6 changes to the display shown in FIG. 10B, and a desired character size is input. In FIG. 10B, reference numeral 65 denotes a character size setting window that is overwritten on a normal character display screen, and includes 9 points (“9 point (Small)”), 1
2 points (“12 point (Standard)”), 18 points (“18 point (Medium)”), 24 points (“24 point (Standard)”)
(Large) ”), 36 points (“ 36 point (Largers)
”), Expanded width (“ Expanded ”), reduced width (“ Conde
nsed ") are displayed, and numerical values from" 1 "to" 7 "are assigned to the respective character sizes.
The selection of a desired character size is executed by inputting the corresponding numerical key and pressing the return key 230. In the case of this embodiment, as shown in FIG. 10B, the currently set size of 12 points is changed to a bold face display, an item that cannot be selected (here, the width reduction (“Co
ndensed ")) is displayed in italic font. Reference numeral 66 denotes a style box showing a display example of font, size, and style of the set character.

Next, in step S7, the character size information set in step S6 is stored in the area of the set character size 116, and in step S8, a second display process is executed.
In the second display process, after setting the character size, a size cursor corresponding to the set character size is displayed at an inputtable position on the LCD screen assuming that a character has been input. After the execution of the second display process in step S8, the process proceeds to step S11.
If not, the process returns to step S3 to wait for the next key input. If the power is turned off in step S11, the process ends.

The details of the second display process in step S8 will be described with reference to the flowchart of FIG.
In the following description, it is assumed that a character size of 24 points has been specified in step S6, and a screen as shown in FIG. In FIG. 10C, reference numeral 67 denotes a cursor having a shape corresponding to the selected 24-point character size, and reference numeral 68 denotes a step S6 described later.
3 shows the cursor line displayed at the line position determined in Step 3.

First, after executing the processing of steps S51 to S52, in step S63, step S6 is performed.
, The set character size 116 (here, 24 points), and the set line space amount 115
(Here, “1”, that is, 1/6 line) and the maximum character size 123 of the cursor line (here, that is, 12 points 1
(1/6 inch for each line), and the display position of the cursor line is determined according to the largest amount. In this case, the largest amount is the character size of 24 points which is the set character size (two lines, that is, the size of 2/6 inch), and the line feed amount from the previous line is determined based on this value. . That is,
The display line position of the cursor is determined at the position "3" from the top margin.

Thereafter, the processing of the aforementioned steps S54 to S55 is executed, and as shown in FIG. 10C, the value displayed on the cursor line position indicator 62 becomes "3", and the size of the cursor 67 becomes the set character size. It changes to the one corresponding to. Finally, in step S66, "1" is set to the character size reflection display flag 119 indicating the provisional display after the character size is set, and the process ends.

(3) Other processing (other than the character input processing and the character size setting processing) In step S9, the temporary line display based on the set character size is canceled and the display returns to the line display displayed in the first display processing. (3) Display processing is executed. Then, step S10
In the processing corresponding to the key input in step S3 (for example, search & replace function, block function, etc.)
After execution of, the process proceeds to step S11. If the power is not turned off, the process returns to step S3 to wait for the next key input. If the power is turned off in step S11, the process ends.

The details of the third display process in step S9 will be described with reference to the flowchart shown in FIG. Here, by the second display process in step S8,
When the screen shown in FIG. 10C is displayed, a key for executing the search & replace function is input, and the display returns to the screen display shown in FIG. It is assumed that the process proceeds to search and replace processing in step S10.

First, in step S91, the set character size reflection display flag 119 is checked. Here, the flag 11
If 9 is off (bit value "0"), the process ends. If it is on (bit value "1"), the process proceeds to step S92. In the state of FIG. 10C, the flag 119 is on. In step S92, the first display process described above is executed, and in step S93, the set character size reflection flag 119 is turned off, and the process ends.

Therefore, according to this embodiment, the character input position is indicated on the LCD by changing the shape (size) of the cursor in accordance with the character size change instruction during document creation / editing, or the character input is performed after the character size change. Is executed, the character size change can be automatically canceled when another input is performed.

[0040]

[Other Embodiments] Although the cursor display processing in the above-described embodiment has been described in connection with the case where the document creation and editing processing is limited to a page, in this embodiment, the cursor indicating the character input position is positioned at the last line of the page. FIG. 11 to FIG. 13 show a case where the cursor display process is performed over two pages.
14 and a cursor display example shown in FIG. Here, only the document editing process of a portion showing a feature different from that of the above-described embodiment will be described, and processes common to the above-described embodiment will be assigned the same step numbers, and description thereof will be omitted.

As a precondition for the processing of this embodiment, assuming that the value of the page length 114 is "54" lines (one line is 1/6 inch), the state of the LCD screen as shown in FIG. Think. FIG. 14A shows the first step S5.
The document created by repeatedly executing the display process is displayed on the LCD
6 is an example displayed above. In FIG. 14A, the cursor line position indicator 62 is "54" lines, indicating that the cursor line is located at the last line of the page.

If the key determined in step S4 is a key for executing character size setting,
After the processing in steps S6 and S7, the fourth display processing is executed in step S108. Details of this processing will be described with reference to the flowchart shown in FIG. In the following description, a character size of 24 points is set in step S6, and the LCD screen is shifted from the state of FIG.
Consider the process that results in the screen shown in (B).

First, the display position of the cursor line on the same page is determined by performing the processing of steps S51 to S52 and step S63. Here, since it is assumed that 24 points are set as the character size, the set character size requires the largest character feed amount,
The display line position determined according to the set character size is “55”. Next, in step S164, the page length 114 in which the determined display row position is set.
(Here, "54" line) is checked to see if it exceeds the range. Here, if the determined display line position falls within the page length, the process proceeds to step S54, and if it exceeds the page length, the process proceeds to step S165.

In step S165, a process for determining the display line position is performed with the display line position as the top line of the next page. In step S166, a page break is displayed, and the flow advances to step S167. For example, as shown in FIG. 14B, if the determined display line position is “55” and exceeds the page length “54”, that line is set as the first line of the next page. As a result, the cursor line position indicator 62 in FIG. 14B becomes the “2” line, and the page indicator 63 becomes the “2” page. Reference numeral 75 denotes a page break. Hereinafter, the processing of steps S54 to S55 and step S66 is executed, and the fourth display processing is completed.

Next, if the key determined in step S4 is neither a character input key nor a key for executing character size setting, the process proceeds to step S109, in which a temporary line display based on the set character size is canceled. A fifth display process for restoring to the original line display is executed. Details of this processing will be described with reference to the flowchart shown in FIG. In this description, when the fourth display process is executed in step S108 and the LCD screen changes to the screen shown in FIG. 14B, for example, it is assumed that a key for executing the search and replace function is input. It is assumed that the display returns to the screen display shown in FIG.

First, following the processing in step S91, it is checked in step S192 whether the temporary display line is the first line of the page. Here, if the provisional display line is not the top line of the page, the process proceeds to step S92, and if it is the top line of the page, the process proceeds to step S193.

In step S193, the display line information 12 indicated by the cursor display position information 117 in the display line information table is displayed.
The first display process of step S92 is performed by subtracting one page information 125 by one and setting the last line of the previous page as the last line.
The process of step 93 is executed and the process ends.

Therefore, according to this embodiment, the same cursor display processing as in the above-described embodiment can be performed even when the document creation / editing is performed over pages.

In the above embodiment, the bitmap type L
Although the case where a CD is used as the display unit has been described, the present invention is not limited to this. For example, even in a character type display, the line position information of the cursor may be rewritten or a blank line may be inserted. For example, provisional line display by setting the character size is possible.

Further, in these embodiments, a personal word processor has been described as an example, but the present invention is not limited to this, and can be applied to, for example, an electronic typewriter.

The present invention may be applied to a system composed of a plurality of devices, or may be applied to an apparatus composed of one device. It is needless to say that the present invention can be applied to a case where the present invention is achieved by supplying a program to a system or an apparatus.

[0052]

As described above, according to the present invention, an input character size is set by selecting an arbitrary character size from an area in which a plurality of character sizes are displayed in a list. If a cursor is displayed at the character input position above at a size corresponding to the set character size, and the displayed line of the cursor does not fit on the currently displayed page, the cursor and the displayed line of the cursor are displayed on the next page. Since the display is performed, the cursor is displayed in the character size set at the character input position regardless of whether or not the cursor fits on the displayed page, and the character input position and the character size can always be identified.
