[0005]

In the conventional information processing apparatus described above, the maximum number of characters in the horizontal direction that can be displayed on the screen of the display device is determined by the type of character font and the like. If the number of characters per hit is smaller, the character string input by the user cannot be displayed at once in the horizontal direction on the screen of the display device.

Therefore, unless the user scrolls the character string horizontally on the screen of the display device, the user cannot read a series of character strings extending over a plurality of lines at a glance, and feels inconvenience. was there.

On the other hand, in an information processing apparatus equipped with a multi-window system, a user displays a window as a work area on a screen of a display device, inputs a character string as work data, and converts the input character string. The work can be performed by displaying the information on the window.

As described above, when the character string input by the user is displayed in the window, the same problem as that described above occurs. That is, if the maximum number of characters in the horizontal direction that can be displayed in the window is smaller than the number of characters per line of the character string input by the user, the character string cannot be displayed in the window at one time in the horizontal direction. If the user does not scroll the text horizontally on the window,
A series of character strings that span multiple lines cannot be read at a glance, which is inconvenient.

Thus, the first character string display means sequentially displays the character string input by the input device on the next line of the screen of the display device for each number of characters determined by the character number calculation means. .

As a result, for example, if the number of character strings input by the input device is 100, the number of characters obtained by the number-of-characters calculating means is "40", and the horizontal direction that can be displayed on the screen of the display device is Is "30", the first line on the screen of the display device is
The thirty thirty character strings are displayed.
The first to 70th 30 character strings are displayed, the third line displays the 81st to 100th 20 character strings, the 31st to 40th 10 character strings, and 7
The first to 80th 10 character strings are not displayed.

Therefore, when the user performs an operation of inputting a switching instruction for switching a character string display method using the input device, the input device inputs the switching instruction. A switch is made to execute the second character string display means instead of the first character string display means.

Therefore, the second character string display means sequentially displays the character string input by the input device on the screen of the display device for each of the maximum number of characters in the horizontal direction that can be displayed on the screen of the display device. Display on the next line.

As a result, for example, if the number of character strings input by the input device is 100, the number of characters obtained by the number-of-characters calculating means is "40", and the horizontal direction that can be displayed on the screen of the display device is Is "30", the first line on the screen of the display device is
The thirty thirty character strings are displayed.
The first to 60th 30 character strings are displayed, the third line displays the 61st to 90th 10 character strings, and the fourth line displays the 91st to 100th 10 character strings. Is displayed.

Therefore, when the first character string display means is executing, when the user cannot read a series of character strings extending over a plurality of lines at a glance, the user can use the input device. By performing an operation of inputting a display method switching instruction, the switching means causes the second character string display means to execute, so that a series of character strings extending over a plurality of lines can be read at a glance. become.

Embodiments of the present invention will be described below with reference to the drawings.

First, a first embodiment of the present invention will be described.

FIG. 1 is a block diagram of the information processing apparatus according to the first embodiment.

In FIG. 1, 101 is a CPU, 102 is a main memory, 103 is a display device, 104 is a keyboard, 1
05 is a hard disk and 106 is a VRAM.

In this embodiment, an example in which the information processing apparatus is a document processing apparatus that performs document processing will be described.

The keyboard 104 is for a user to input a character string constituting a document and a format of the document.

FIG. 2 is a diagram showing the display contents of the screen of the display device 103 when the user inputs a format.

When the user instructs to input a format, for example, by pressing a format key provided on the keyboard 104, a format setting menu shown in FIG. . As shown in FIG. 2, in the present embodiment, the format includes a character size and a character spacing and a line spacing. Therefore, the user can set these pieces of information so as to have a desired format.

FIG. 3 is a diagram showing the display contents of the screen of the display device 103 when the user inputs a character string.

As shown in FIG. 3, a cursor is displayed on the screen of the display device 103, and character strings input by the user from the keyboard 104 are sequentially displayed at the position where the cursor is displayed. Becomes That is, every time a character is input, the cursor moves backward by one character to indicate the input position of the next character. When the user presses an arrow key provided on the keyboard 104, the cursor moves in conjunction therewith.

Returning to FIG. 1, the character string and the format input from the keyboard 104 are temporarily stored in the main memory 102, and are stored in the main memory 102 by the CPU 101 in accordance with the format stored in the main memory 102. String
By writing in the VRAM 106, the screen shown in FIG. 3 is realized.

The CPU 101 is connected to the hard disk 1
05 are stored in the main memory 102
By loading and executing the process, various processes for realizing the operation of the document processing apparatus of the present embodiment, including a process of writing a character string in the VRAM 106, are realized. The hard disk 105 has a main memory 102.
Can be stored as one document file in association with the file name input by the user from the keyboard 104.

In the present embodiment, a character string input from the keyboard 104 and stored in the main memory 102 is displayed on the screen of the display device 103 in accordance with a format input from the keyboard 104 and stored in the main memory 102. 1 and a second display method in which a character string input by the user from the keyboard 104 and stored in the main memory 102 is displayed on the screen of the display device 103 according to a predetermined format. Thus, the display method desired by the user can be executed.

More specifically, the predetermined format is a format in which the maximum number of characters in the horizontal direction that can be displayed on one screen of the display device 103 is the number of characters per line.

The user can give an instruction to execute a desired display method by, for example, pressing a switching key provided on the keyboard 104.

FIG. 4 is a state transition diagram relating to the writing process of the CPU 101.

As shown in FIG. 4, in an initial state, the CPU 101 is in a state 401 for executing the first display method. That is, in the first display method execution state 401, C
The PU 101 converts the character string stored in the main memory 102 into
VRAM 10 according to the format stored in main memory 102
6 is written.

In the first display method execution state 401,
When the switching key is pressed, the state transits to the state 402 in which the second display method is executed. That is, in the second display method execution state 402, the CPU 101 converts the character string stored in the main memory 102 into a VRAM according to a predetermined format.
A write process for writing to 106 is performed.

In the second display method execution state 402,
When the switching key is pressed, the state transits to the first display method execution state 401 again.

FIG. 5 is a flowchart of the writing process performed in the first display method execution state 401.

As shown in FIG. 5, the CPU 101 first obtains the number of characters K per line from the format stored in the main memory 102 (step 501).

In this embodiment, as shown in FIG. 2, since the format includes the character size and the character interval, the number K of characters per line can be obtained from the character size and the character interval. Note that the format may include the number of characters K per line itself.

The VRAM 106 is provided on the display device 10.
3 is a memory having the size of one screen, and the maximum number L of characters in the horizontal direction that can be displayed on one screen of the display device 103 is determined by the type of character font and the like. If the number of characters per hit is K,
K character strings can be written in the horizontal direction of the VRAM 106,
2 can be written to the VRAM 106. However, if the maximum number of characters L <the number of characters K per line, K character strings cannot be written in the horizontal direction of the VRAM 106, and the character strings input from the keyboard 104 and stored in the main memory 102 are not written. Not all can be written to the VRAM 106.

Then, the CPU 101 compares the maximum number of characters L with the number of characters K per line (step 502). If the maximum number of characters L ≧ the number of characters K per line, the CPU 101 stores the characters stored in the main memory 102. The column is divided for each K characters (step 503), and written into the VRAM 106 so that the K character strings thus divided are on the same line (step 50).
4).

As a result, for example, when the maximum number of characters L = 30 and the number of characters per line K = 30, the screen of the display device 103 is as shown in FIG. here,
Each number in a circle represents a character, and in particular, the number represents the order in which the characters were input. Further, for example, the maximum number of characters L = 30, and the number of characters per line K =
If it is 20, the screen of the display device 103 is as shown in FIG. As described above, when the maximum number of characters L ≧ the number of characters K per line, the character string stored in the main memory 102 is displayed on the screen of the display device 103 in such a manner that a line feed is performed every K character strings. Is displayed.

The CPU 101 determines that the maximum number of characters L> 1
If the number of characters per line is K, the character string stored in the main memory 102 is divided into K characters (step 50).
5) The VRAM 106 is set so that the first to L-th L character strings of the K character strings obtained by the division are on the same line.
(Step 506).

As a result, for example, if the maximum number of characters L = 30 and the number of characters per line K = 40, 40
Only 30 character strings of the VRAM10
6, and the remaining ten character strings are not written, so that the screen of the display device 103 is as shown in FIG.

Therefore, when the first display method is being executed, if the maximum number of characters L <the number of characters per line K, the user can display a series of characters over a plurality of lines on the display device 103. Since the column cannot be read at once, it is necessary to press the arrow keys to scroll the character string on the screen in the horizontal direction, which is inconvenient.

Therefore, in such a case, the user can press the switch key to transition to the second display method execution state 402, and execute the second display method.

FIG. 9 is a flowchart of the writing process performed in the second display method execution state 402.

As shown in FIG. 9, the CPU 101 first divides the character string stored in the main memory 102 into L character strings (step 901), so that the L character strings are on the same line. , Is written to the VRAM 106 (step 902).

As a result, for example, when the screen of the display device 103 is as shown in FIG.
The screen of 03 changes as shown in FIG. Further, for example, even when the screen of the display device 103 is as shown in FIG. 7, the screen of the display device 103 changes as shown in FIG. In this case, the number of characters displayed on one screen of the display device 103 increases. Further, for example, even when the screen of the display device 103 is as shown in FIG. 8, the screen of the display device 103 changes as shown in FIG. In this case, a character string that has not been displayed on the screen of the display device 103 is also displayed.

When the screen of the display device 103 is as shown in FIG. 20,
When transitioning to the second display method execution state 402,
When the switching key is pressed, the state is changed to the first display method execution state 401 again, and the first display method can be executed.

As a result, the screen of the display device 103 is displayed as shown in FIG.
In the example shown in FIGS.
The screen changes to the screen displayed at the top of the screen.

As described above, according to this embodiment,
If a series of character strings extending over a plurality of lines cannot be read at a glance while the first display method is being executed, the user simply presses the switching key to execute the second display method. Can be read, so that a series of character strings that span multiple lines can be read at a glance.

In this embodiment, the user can freely give an instruction using the switching key.
Only if the maximum number of characters L <the number of characters per line K,
An instruction using a switching key may be provided.

Also, in this embodiment, when the CPU 101 starts the writing process shown in FIG.
When the writing process shown in (1) is started, the character string is written to the VRAM 106 from the beginning and the cursor is displayed at the beginning of the screen of the display device 103.
It is possible to prevent the cursor position displayed on the screen of the display device 103 from being changed.

This can be achieved by writing the character and the character string before and after the character in the VRAM 106 based on the character written in the position on the VRAM 106 corresponding to the cursor position at the start of the writing process.

As a result, for example, in the example shown in FIG. 8, when the switching key is pressed, the screen of the display device 103 is displayed as shown in FIG.
It changes as shown in FIG.

Further, both the cursor position and the character displayed at the cursor position can be moved to a predetermined position in the screen of the display device 103.

In this case, the cursor position is moved to a predetermined position (for example, the top of the screen of the display device 103), and the data is written to a position on the VRAM 106 corresponding to the cursor position at the start of the writing process. VRAM corresponding to the cursor position after movement
The character and the character string before and after the character are written in the VRAM 106 so as to correspond to the position on the VRAM 106.

As a result, for example, in the example shown in FIG. 8, when the cursor is displayed at the position where the 35th character is displayed, when the switching key is pressed, the screen of the display device 103 is displayed. Changes as shown in FIG.

Further, when the cursor position is in the middle of a series of character strings (for example, one sentence), the beginning of the sentence can be moved to the beginning of the screen of the display device 103.

This is a character (for example, a character string indicating the delimitation of the relevance of the character string at the position closest to the cursor position in the character string written ahead of the cursor position at the start of the writing process). , A character indicating a period and a character indicating a line feed), and the character string following the next character may be written into the VRAM 106 with the next character as the head.

As a result, for example, in the example shown in FIG. 8, the cursor is displayed at the position where the 35th character is displayed, and the 28th character is a character indicating a period,
Assuming that the th to 34th characters are characters other than a character indicating a line feed and a character indicating a period, when the switching key is pressed, the screen of the display device 103 changes as shown in FIG.

In this case, there is a case where "." Is used as a period and a case where "." Is used. Therefore, when "." You can't do that. Therefore, "."
It may be determined whether or not the subsequent character is a number, and if it is a number, "." May be regarded as a decimal point.

Next, a second embodiment of the present invention will be described.

The configuration of the information processing apparatus according to the second embodiment is
It is the same as FIG.

Also in this embodiment, an example in which the information processing apparatus is a document processing apparatus for performing document processing will be described.

Further, a diagram showing the display contents of the screen of the display device 103 when the user inputs a format and a diagram showing the display contents of the screen of the display device 103 when the user inputs a character string are shown in FIG. 2 and FIG.

This embodiment differs from the first embodiment in the contents of the second display method. That is, in the present embodiment, the character string input from the keyboard 104 and stored in the main memory 102 is converted into the display device 1 according to the format input from the keyboard 104 and stored in the main memory 102.
03, a first display method to be displayed on the screen 03, and a keyboard 1
And a second display method of displaying a character string input from the main memory 104 and stored in the main memory 102 in a display area secured on the screen of the display device 103 according to a predetermined format. , The first display method is always executed, and the second display method can be executed when the user desires.

More specifically, the predetermined format is a format in which the maximum number of characters in the horizontal direction that can be displayed in the display area is the number of characters per line.

The user can execute the instruction to execute the second display method and the instruction to stop the execution by, for example, pressing a switching key provided on the keyboard 104.

FIG. 13 is a state transition diagram relating to the writing process of the CPU 101.

As shown in FIG. 13, the CPU 101 is in an initial state 1301 for executing the first display method. That is, in the first display method execution state 1301, the CPU 101 converts the character string stored in the main memory 102 into a VRA according to the format stored in the main memory 102.
A write process for writing to M106 is performed.

When the switching key is pressed in the first display method execution state 1301, the state transits to the state 1302 in which the second display method is executed. That is, in the second display method execution state 1302, the CPU 101
2 to write the character string stored in the VRAM 106 into the VRAM 106 in accordance with a predetermined format.

When the switching key is pressed in the second display method execution state 1302, the state transits again to the first display method execution state 1301.

Note that the flowchart of the writing process performed in the first display method execution state 1301 is the same as that in FIG.

Therefore, in this embodiment, as in the case of the first embodiment, when only the first display method is executed, the maximum number of characters in the horizontal direction that can be displayed on one screen of the display device 103 is obtained. If L <the number of characters per line K, the user:
In the display device 103, a series of character strings extending over a plurality of lines cannot be read at one time.
It is necessary to press the arrow keys to scroll the character string horizontally on the screen, which is inconvenient.

Therefore, in such a case, the user can press the switch key to transit to the second display method execution state 1302 and execute the second display method.

FIG. 14 shows the second display method execution state 1302.
6 is a flowchart of a writing process performed in step S1.

As shown in FIG. 14, the CPU 101 first divides the character string stored in the main memory 102 into M characters, which is the maximum number of characters in the horizontal direction that can be displayed in the display area (step 1401). The divided M character strings are written in an area on the VRAM 106 corresponding to the display area so as to be on the same line (step 1402).

Since the character string has already been written in the VRAM 106 by the writing process shown in FIG. 5, the area in the VRAM 106 corresponding to the display area is
The new character string will be overwritten.

As a result, for example, when the screen of the display device 103 is as shown in FIG.
The screen 03 changes as shown in FIG. Also, for example, when the screen of the display device 103 is as shown in FIG. 7, the screen of the display device 103 changes as shown in FIG.

Further, for example, the screen of the display device 103 is
When the display is as shown in FIG.
Screen changes as shown in FIG. The example shown in FIG. 17 shows a case where the maximum number of characters M = 10 for the number of characters K per line K = 40.
All of the 0 character strings are displayed as 40 character strings of 4 lines in the display area.

When the screen of the display device 103 is as shown in FIGS. 15 to 17, that is, when the display device 103 has transitioned to the second display method execution state 1302, When the switching key is pressed, the state is changed to the first display method execution state 1301 again, and the first display method can be executed.

As a result, the screen of the display device 103 is displayed as shown in FIG.
In the example shown in FIG. 8 to FIG.
The screen changes to the screen displayed at the top of the screen of No. 3.

As described above, according to the present embodiment,
If only a first display method is executed and a series of character strings extending over a plurality of lines cannot be read at a glance, the user simply presses a switch key to display a second display. The method can be executed so that a series of strings spanning multiple lines can be read at a glance.

In this embodiment, the user can freely give an instruction using the switching key.
Only if the maximum number of characters L <the number of characters per line K,
An instruction using a switching key may be provided.

In this embodiment, when the CPU 101 starts the writing process shown in FIG. 14, the CPU 101 writes the character string from the beginning to the area on the VRAM 106 corresponding to the display area, and moves the cursor in the display area ( In particular, the character string is displayed at the top of the display area so that a character string cannot be input outside the display area.
The character written at the position on the VRAM 106 corresponding to the cursor position at the start of the writing process shown in FIG. 4 is changed to the VRAM 10 corresponding to the moved cursor position.
The character and the character string before and after the character may be written in an area on the VRAM 106 corresponding to the display area so as to correspond to the position on the VRAM 6.

As a result, for example, in the example shown in FIG. 8, if the cursor is displayed at the position where the 35th character is displayed, when the switch key is pressed, the screen of the display device 103 is displayed. Changes as shown in FIG.

Further, when the cursor position is in the middle of a series of character strings (for example, one sentence), the beginning of the sentence can be moved to the beginning of the display area.

This indicates a character-relevance segment located closest to the cursor position in the character string written ahead of the cursor position at the start of the writing process shown in FIG. A character (for example, a character indicating a period and a character indicating a line feed) is searched, and a character string subsequent to the character indicating the searched delimiter is set as a leading character on the VRAM 106 corresponding to the display area. What is necessary is just to write in the area | region of.

As a result, for example, in the example shown in FIG. 8, the cursor is displayed at the position where the 35th character is displayed, and the 28th character is a character indicating a period,
Assuming that the th to thirty-fourth characters are characters other than a character indicating a line feed and a character indicating a period, when the switching key is pressed, the screen of the display device 103 changes as shown in FIG.

In this case, it is considered that a period "." Is used and a period "." Is used. Therefore, when "." You can't do that. Therefore, "."
It may be determined whether or not the subsequent character is a number, and if it is a number, "." May be regarded as a decimal point.

In this case, if one sentence is long,
If the head of the sentence is displayed at the head of the display area, the cursor position may not be displayed in the display area.
Therefore, the cursor may be further moved to the beginning of the text or the end of the display area.

Further, in the present embodiment, the size of the display area is fixedly determined, but the user may be able to change the size to a desired size.

In this case, in the writing process shown in FIG. 14, the maximum number of characters M may be changed according to the size of the display area.

Next, a third embodiment of the present invention will be described.

The configuration of the information processing apparatus according to the third embodiment is shown in FIG.
1 is the same as FIG. 1, but in particular, in the present embodiment, it is assumed that the information processing apparatus has a multi-window system.

In an information processing apparatus equipped with a multi-window system, as shown in FIG.
3 on the screen, a character string as work data is input, and the input character string is displayed on the window 2101 so that the work can be performed. In the example of FIG. 21, the other window 2102 is also displayed on the display device 1.
03 is secured on the screen. Note that the sizes of these windows 2101 and 2102 can be arbitrarily changed by the user.

In this embodiment, a case where the work performed by the user is a document creation work will be described as an example.

Therefore, when the user inputs a form,
The display contents (format setting menu) shown in FIG. 2 are displayed in the window. When the user inputs a character string, the display content shown in FIG. 3 is displayed in the window as shown in FIG.

In the present embodiment, the first embodiment is applied to an information processing apparatus equipped with a multi-window system. That is, in the present embodiment, the keyboard 104
The character string input from and stored in the main memory 102 is
A first display method for displaying in a window according to a format input from the keyboard 104 and stored in the main memory 102, and a first display method input from the keyboard 104 and
And a second display method for displaying the character string stored in the window 2 in a window according to a predetermined format so that the user can execute a desired display method. is there.

More specifically, the predetermined format is a format determined so that the maximum number of characters in the horizontal direction that can be displayed in the window is the number of characters per line.

Further, the user can give an instruction to execute a desired display method by, for example, pressing a switching key provided on the keyboard 104.

FIG. 22 is a state transition diagram relating to the write processing of the CPU 101.

As shown in FIG. 22, the CPU 101 is initially in a state 2201 for executing the first display method. That is, in the first display method execution state 2201, the CPU 101 converts the character string stored in the main memory 102 into a VRA according to the format stored in the main memory 102.
A write process for writing to M106 is performed.

When the switching key is pressed in the first display method execution state 2201, the state transits to a state 2202 in which the second display method is executed. That is, in the second display method execution state 2202, the CPU 101
2 to write the character string stored in the VRAM 106 into the VRAM 106 in accordance with a predetermined format.

When the switching key is pressed in the second display method execution state 2202, the state transits to the first display method execution state 2201 again.

FIG. 23 shows a first display method execution state 2201.
6 is a flowchart of a writing process performed in step S1.

As shown in FIG. 23, the CPU 101 first obtains the number of characters K per line from the format stored in the main memory 102 (step 2301).

Also in this embodiment, as shown in FIG. 2, since the format includes the character size and the character spacing, the number K of characters per line can be obtained from the character size and the character spacing.

Subsequently, the CPU 101 obtains the maximum number N of characters in the horizontal direction that can be displayed in the window serving as the work area (step 2302), and compares the maximum number N of characters with the number K of characters per line (step 2303). ), If the maximum number of characters N ≧ the number of characters K per line, the main memory 102
Is divided into K character strings (step 2).
304) Then, the divided K character strings are written in an area on the VRAM 106 corresponding to the window so that the K character strings are on the same line (step 2305).

As a result, for example, when the maximum number of characters N = 20 and the number of characters per line K = 20, the screen of the display device 103 is as shown in FIG. Also,
For example, when the maximum number of characters N = 20 and the number of characters per line K = 15, the screen of the display device 103 is as shown in FIG. Thus, the maximum number of characters N ≧ 1
When the number of characters per line is K, the character string stored in the main memory 102 is displayed on the window such that a line feed is performed every K character strings.

Also, the CPU 101 determines that the maximum number of characters N> 1
If the number of characters per line is K, the character string stored in the main memory 102 is divided into K characters (step 230).
6) Write into the area on the VRAM 106 corresponding to the window so that the first to Nth N character strings of the K character strings obtained by the division become the same line (step 2).
307).

As a result, for example, when the maximum number of characters N = 20 and the number of characters per line K = 30, 30
Only the 20 character strings of the 10 character strings are written in the area on the VRAM 106 corresponding to the window, and the remaining 10 character strings are not written. Therefore, the screen of the display device 103 is shown in FIG. As shown.

Therefore, when the first display method is being executed, if the maximum number of characters N <the number of characters per line K, the user will be able to access a plurality of windows in the window secured on the screen of the display device 103. You will not be able to read a series of strings across the line at once, so you will need to press the arrow keys to scroll the strings horizontally in the window or to enlarge the window size There is inconvenience.

Therefore, in such a case, the user can press the switch key to transition to the second display method execution state 2202, and execute the second display method.

FIG. 27 shows a second display method execution state 2202.
6 is a flowchart of a writing process performed in step S1.

As shown in FIG. 27, first, the CPU 101 obtains the maximum number N of characters in the horizontal direction that can be displayed in the window serving as the work area (step 2701).

Subsequently, the CPU 101 sets the main memory 102
Is divided into N character strings (step 27).
02), so that the divided N character strings are on the same line,
The data is written in the area on the VRAM 106 corresponding to the window (step 2703).

As a result, for example, when the screen of the display device 103 is as shown in FIG. 24, the screen of the display device 103 changes as shown in FIG. Also,
For example, even when the screen of the display device 103 is as shown in FIG.
Changes as shown in FIG. Also, for example, the display device 103
Also, when the screen of FIG. 26 is as shown in FIG. 26, the screen of the display device 103 changes as shown in FIG.
In this case, a character string that has not been displayed in the window is also displayed.

When the screen of the display device 103 is as shown in FIG. 28,
When the switching key is pressed during the transition to the second display method execution state 2202, the state is again changed to the first display method execution state 2201, and the first display method can be executed.

As a result, the screen of the display device 103 is displayed as shown in FIG.
In the examples shown in FIGS. 4 to 26, the cursor changes to the screen displayed at the top of the window.

In both the writing process shown in FIG. 23 and the writing process shown in FIG. 27, the CPU 101 determines the display contents outside the window.
The data is directly written in an area other than the area on the VRAM 106 corresponding to the window.

As described above, according to the present embodiment,
If a series of character strings extending over a plurality of lines cannot be read at a glance while the first display method is being executed, the user simply presses the switching key to execute the second display method. Can be read, so that a series of character strings that span multiple lines can be read at a glance.

In this embodiment, the user can freely give an instruction using the switching key.
Only if the maximum number of characters N <the number of characters per line K,
An instruction using a switching key may be provided.

In this embodiment, when the CPU 101 starts the writing process shown in FIG. 23 and starts the writing process shown in FIG. 27, it corresponds to the window from the beginning of the character string. Although writing to the area on the VRAM 106 and displaying the cursor at the top of the window are performed, it is possible to prevent the cursor position displayed in the window from being changed.

This means that, based on a character written at a position on the VRAM 106 corresponding to the cursor position at the start of the writing process, the character and the character string before and after the character are stored in an area on the VRAM 106 corresponding to the window. What is necessary is just to write in.

As a result, for example, in the example shown in FIG.
When the switching key is pressed, the screen of the display device 103 changes as shown in FIG.

Also, both the cursor position and the character displayed at the cursor position can be moved to a predetermined position in the window.

In this case, the cursor position is moved to a predetermined position (for example, the top of the window), and the character written at the position on the VRAM 106 corresponding to the cursor position at the start of the writing process is changed. The character and the character string before and after the character are written in an area on the VRAM 106 corresponding to the window so as to correspond to the position on the VRAM 106 corresponding to the cursor position after the movement.

As a result, for example, in the example shown in FIG.
Assuming that the cursor is displayed at the position where the fifteenth character is displayed, when the switching key is pressed, the screen of the display device 103 changes as shown in FIG.

Further, when the cursor position is in the middle of a series of character strings (for example, one sentence), the beginning of the sentence can be moved to the beginning of the screen of the display device 103.

[0149] This is a character (for example, a character string indicating the delimitation of the relevance of the character string at the position closest to the cursor position in the character string written ahead of the cursor position at the start of the writing process). , A character indicating a period and a character indicating a line feed), and writing a character string following the character following the character indicating the searched delimiter into an area on the VRAM 106 corresponding to the window. What should I do?

As a result, for example, in the example shown in FIG. 26, the cursor is displayed at the position where the fifteenth character is displayed, and the tenth character is a character indicating a period, and
If the 14th to 14th characters are characters other than the character indicating a line feed and the character indicating a period, when the switching key is pressed, the screen of the display device 103 changes as shown in FIG.

In this case, it is conceivable to use "." As a period and "." As a period, so when using "." You can't do that. Therefore, "."
It may be determined whether or not the subsequent character is a number, and if it is a number, "." May be regarded as a decimal point.

In this embodiment, the first embodiment is applied to an information processing apparatus equipped with a multi-window system. The second embodiment is applied to an information processing apparatus equipped with a multi-window system. May be applied.

In this case, in the window,
The display area in the second embodiment is displayed as a pop window.
Since it can be easily inferred from this embodiment and the third embodiment, the description is omitted.

In all the embodiments described above,
Each time the switch key is pressed, the CPU 101 starts the writing process. However, two VRAMs 106 are prepared,
2 is stored in one VRAM 106.
The writing process according to the first display method is performed, and the writing process according to the second display method is performed in the other VRAM 106. Each time the switching key is pressed, the VRAM 106 to be displayed on the display device 103 is switched. You may do so. In this case, the display contents before the switching key is pressed can be restored.

In all of the above embodiments,
Although the character size of the character string written by the writing process by the first display method is the same as the character size of the character string written by the writing process by the second display method, the second display method It may be possible to change the character size of a character string to be written in the writing process according to.

For example, when the character size is reduced,
Strings are harder to see, but more strings can be displayed. Conversely, when the character size is increased, the number of characters to be displayed is reduced, but the character string is easy to see, so that in an aging society expected in the future, convenience for the elderly who cannot easily see small characters will increase.

In this case, in each embodiment, it is necessary to change the maximum number of characters L, M, and N according to the character size.

For example, when the character size is increased in the second embodiment, when the switching key is pressed when the screen of the display device 103 is as shown in FIG. The screen of 103 changes as shown in FIG. Further, for example, when the character size is reduced in the second embodiment, when the switching key is pressed when the screen of the display device is as shown in FIG. The screen changes as shown in FIG.

Further, in particular, the first embodiment can be applied to a small information processing device such as an electronic organizer in which the display device 103 has a structure incorporated in the main body of the information processing device. However, in such a small information processing device,
Since the screen of the display device 103 is small, a remarkable effect can be obtained.

[0160]

As described above, according to the information processing apparatus of the present invention, when a user cannot read a series of character strings extending over a plurality of lines at a glance,
It becomes possible to read with a simple operation.
