Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a word processor, and more particularly to a display device thereof.

(Prior art) Word processors can be roughly divided into those equipped with large display devices that can display one page's worth of characters, symbols, etc. at a time, and those that can only display a limited number of decimal characters, symbols, etc. Some are equipped with a liquid crystal display.

(Problems to be Solved by the Invention) Word processors equipped with liquid crystal displays that display a small number of characters are generally small, convenient to carry, and inexpensive. Furthermore, since the keyboard and the liquid crystal display are arranged so close together that they are in the same field of view, it is suitable for partial character input. However, since the number of displayed characters is small, the displayed information is too small to accurately grasp the overall image of the input text, and editing the created text is extremely troublesome.

On the other hand, a word processor equipped with a large display device that can display one page's worth of characters, symbols, etc. at once displays a large number of characters and symbols on the large display device.
It is excellent when editing a created document because it displays a state close to the final image of the printed matter. However, the vR device is too large to be portable and is expensive. Moreover, the keyboard and large display device are separate units, and the two devices are not in the same field of view, so who is the operator who cannot use blind touch when inputting characters, editing, etc.? J! The problem was that the line had to be moved frequently, which increased fatigue.

Therefore, each word processor has its advantages and disadvantages.

(Objective of the Invention) The object of the present invention is to solve the above-mentioned problems by combining the excellent characteristics of a word processor equipped with a large display device and the excellent characteristics of a word processor equipped with a liquid crystal display, and to provide a method for combining the excellent characteristics of a word processor equipped with a large display device and a word processor equipped with a liquid crystal display. To provide a word processor with excellent operability and ergonomics by identifying where on a large display HM a displayed character group is displayed.

(Means for Solving the Problems) In order to achieve the above object, the present invention includes a two-dove 0t1 Futsusa main body having an input means for inputting characters, symbols, etc., and an input means provided in the word processor main body. In a word processor, the word processor is equipped with a storage means for storing character data such as characters, symbols, etc., and a display device provided in the word processor main body and capable of displaying decimal numbers of characters, symbols, etc. inputted by the input means. A large display device capable of displaying a large number of input characters, symbols, etc. is provided, and a character data group corresponding to the number of character strings that can be displayed on the display device is read out from the character data group stored in the storage means, a first display control means for displaying the character group on the display based on the data; and a first display control means for displaying the character group on the display device based on the data, and a number that can be displayed on the large display device from the character data group stored in the storage means; a second display control means for reading a large number of character data including character data of a character string to be displayed and displaying a group of characters on a large display device based on the character data; and characters displayed on the display device. an indexing means for determining a group from the storage means; The gist of the invention is a word processor comprising: index display control means for displaying an index for distinguishing from a group of displayed characters;

(Operation) The display control means of measure 1 reads out a character data group of character subdivisions of the number that can be displayed on the display device provided in the word processor main body from the character data group stored in the storage means provided in the word processor main body, Based on the same data, the character group is displayed on the display.

The second display control means selects the character data of the character string to be displayed on the display device from the character data group stored in the storage means, the number of which can be displayed on a large display device separate from the main body of the word processor. Read out a large number of character data containing characters, and create characters based on that character data! Display lY on the same large display device.

At this time, the indexing means indexes the character group displayed on the display from the storage means.

Based on the determination by the indexing means, the index display control means converts the character group displayed on the large-sized display device into a character group corresponding to the character group displayed on the display device. Display indicators to distinguish between

(Example) An example in which the present invention is embodied in a Japanese word processor will be described below with reference to the drawings.

In FIG. 1, a keyboard 3 is provided on the front side of a main body case 2 of a word processor 1, and a printer 4 is provided on the front side. The keyboard 3 is provided with a 12-digit liquid crystal display 5 (number of displayed characters: 12). Various operation keys are arranged on the keyboard 3, such as character keys for inputting alphabetic and hiragana characters and numbers, space keys, line feed keys, page feed keys, etc.
In addition, various known keys are provided. Furthermore, four cursor movement keys 3a to 3d are provided on the keyboard 3.

Large display device 6 separate from word processor 1
are detachably connected by a cable 7, and in this embodiment, characters of up to 25 lines and 40 digits (1000 characters) can be displayed on a screen 8 having a deoxidizing degree of 11,400 dots and a horizontal dot of 640 dots.

Next, the electrical configuration of this word processor 1 will be explained with reference to the electrical block circuit diagram shown in FIG.

The microcomputer 10 built into the main body case 2 includes a central processing unit (hereinafter referred to as CPU) 11, a program memory 12 consisting of a read-only memory (ROM),
and a working memory 13 consisting of a readable and rewritable memory (RAM). CPU1
1 connects the keyboard 3 via the keyboard driver 14.
, the liquid crystal display 5 via a display controller 15 , and the printer 4 via a print driver 16 . In addition, CPLIII has 17 memories for the old mountain, 18 character generators, and 91 text memos.
It is connected to various types of memory such as 9. Furthermore, CPU1
1 is connected to the large display device 6 via a cable 7.

The program memory 12 stores various III@ programs such as a Japan 3B word processor control program, a keyboard control program, a printer control program, a liquid crystal display control program, a large display control program, and a cursor and index control program. The CPU 12 operates according to these various control programs.

The dictionary memory 17 stores data of various kanji characters. The character generator 18 stores character pattern data such as characters and symbols printed in a tod matrix for each typeface.

Further, the document memory 19 stores document data consisting of character data, space data, line feed data, etc. input by the operator by operating the character keys, space key, line feed key, etc. of the keyboard 3. .

Next, the operation of the word processor 1 configured as described above will be explained.

Now, when the large display 1m6 is connected to the word processor 1 via the cable 7 and the printing format on the printing paper is set in advance using the keyboard 3 so that one page has 25 lines and 40 digits, the CPU 11 uses the Japanese word processor control 70 Based on the program, the page layout of the document memory 19 is set to 25 lines and 40 columns per page, as shown in FIG.

At this time, the text displayed on the screen of the large display device 6 is displayed up to 25 lines and 40 columns, which is the same as the print format set above.

When this allocation is completed, the CPU 11 allocates one part of the document memory 19 based on the liquid crystal display control program.
Of the document data stored on the page, read out the 12th character data counting from the first stored character data, and write the 12 characters etc. corresponding to each data as shown in Figure 4. The images are displayed on the liquid crystal display 5 in order from the left. At the same time, the CPU 11 reads out all the document data stored in the first page of the document memory 19 based on the large display control program, transfers it to the large display device 6, and displays the first page on the screen 8 as shown in FIG. Characters etc. corresponding to each character data etc. for one page are displayed.

Further, the CPU 11 causes the cursor 5a displayed on the liquid crystal display 5 to be displayed below the characters displayed in the leftmost column position based on the cursor and index control program.

Further, CPtJll displays a cursor 6a on the screen 8 of the large display device 6. CPLJl
l determines which character is indicated by the cursor 5a of the display device 5, and also determines where on the screen 8 of the large display device 6 the character corresponding to the indicated character is displayed, and displays the corresponding character. Place the cursor 6a at . Therefore, at this point, the cursor 6a is positioned at the top left end of the screen 8 of the large display device 6.
will be located.

The cpuii also determines which character data in the document memory 19 is used to display the first character of the character string displayed on the liquid crystal display 5, that is, the character displayed at the left end, and displays the character data on the liquid crystal display 5. 1 displayed in 5
A character string displayed on a large display device 6 corresponding to two character strings is determined. CPtJll displays this determined character string surrounded by a rectangular frame-like indicator 6b to distinguish it from other characters displayed on the screen 8.

When the operator operates the four cursor movement keys 3a to 3d as appropriate from this initial display state, the CPU responds to the ON signal of the operation key, and the key moves to the cursor 5a, 6.
It is determined whether the cursor movement key is for moving a to the right, left, upward, or downward.

In the case of the right cursor movement key 3a, the CPU1
1 is the cursor 5a of the display 5 and large display device 6 for the number of times of operation in response.

Move 6a to the right. At this time, CPtJll calculates what character data is at the movement position of each cursor 5a, 6a and where its display position is, and moves the cursor 5a, 6a to the left based on the calculated value. let

Also, when the right cursor movement key 3a is operated while the cursor 5a of the liquid crystal display 5 is displaying the rightmost column of the display 5, the CPLJll will move the cursor 6a of the large display 8Je position 6 to the right. However, the cursor 5a of the liquid crystal display 5 remains at its rightmost position, and the character that comes after the character displayed in the rightmost column is shifted 19 left (leftmost). characters are deleted) and displayed in the rightmost column.

When the character group displayed on the liquid crystal display 5, that is, the character string, changes, the CPU 11 determines which character data in the document memory 19 corresponds to the first character of the character string displayed on the liquid crystal display 5. At the same time, the character data group of the displayed character string is determined based on the determined character data. That is, the character strings displayed on the large display device 6 that correspond to the 12 character strings displayed on the liquid crystal display 'a5 are determined. And CPU
ii displays the determined character string surrounded by a rectangular frame-like indicator 6b. In this case, the square frame-shaped index 6b has a total of 1
9 will be shifted to the right.

Similarly, the CPU 11 moves the cursors 5a, 5a of the display 5 and the large display device 6 to the left in response to the ON signal of the left cursor movement key 3b. At this time,
Similarly to the above, the CPU 11 determines what character data is at the movement position of each cursor 5a, 6a and where its display position is, and moves the cursor 5a, 6a to the left based on the determined value. .

Further, when the left cursor movement key 3a is operated while the cursor 5a of the liquid crystal display 5 is displaying the leftmost column of the display 5, the CPU 11 moves the cursor 6a of the large display device 6 to the left. However, the cursor 5a of the liquid crystal display 5 remains at its leftmost position, and the character in front of the character displayed in the leftmost column is shifted 19 to the right (in the rightmost column). (the characters are deleted) and displayed in the leftmost column.

When the character string displayed on the liquid crystal display 5 changes, C
The PU 11 determines which character data in the document memory 19 is the first character of the character string displayed on the liquid crystal display 5, and also determines the character data group of the displayed character string based on the determined character data. Figure out. That is, the character strings displayed on the large display device 6 that correspond to the 12 character strings displayed on the liquid crystal display 5 are determined. Then, the CPU II displays the determined character string surrounded by a rectangular frame-shaped indicator 6b.

In this case, the square frame-shaped index 6b is entirely shifted to the left by 19.

Note that if the right cursor movement key 3a is operated with the index 6a located at the right corner of the screen 8 and the cursor 6a pointing to the rightmost character as shown in FIG.
determines that the cursor 6a is at the right end of the line, invalidates the on signal of the cursor key 3a, and moves the cursor 6a to the right end of the line.
a and the index 6b are kept stationary at that position without being moved. At the same time, since the cursor 6a and index 6b do not move, the CPU 11 prevents the character string and cursor 5a displayed on the liquid crystal display 5 at that time from moving.

Conversely, when the left cursor movement key 3a is operated with the index 6b located at the left corner of the screen 8 and the cursor 6a also pointing to the leftmost character, CPIJII similarly moves the cursors 5a, 6a and index 6b. is prevented from moving to its position C.

Next, the case where the upward or downward cursor movement keys 3c and 3d are operated will be described.

Now, if you operate the upward cursor movement key 3c, the CPI,
111 responds to the on signal and turns on the large display vt.
The cursor 6a at position 6 is moved to the line above 19 as shown by the broken line in FIG. 7, and the index 6b is shifted directly above 19. At this time, the CPU 11 determines the character data at the movement position of the cursor 6a, and
Character data that is distinguished from other character groups by the index 6b is determined. Then, the CPU 11 reads out the character data group, erases all the character strings previously displayed on the liquid crystal display 5, and displays them sequentially, and displays a cursor 5a under the corresponding characters.

Similarly, when the downward cursor movement key 3d is operated, CP
In response to this ON signal, U11 shifts the cursor 6a and index 6b of the large display device 6 to the row below 19, and corresponds to the character string and cursor 6a that are distinguished from other character groups by the index 6b. A cursor 5a is displayed on the liquid crystal display 5 below the characters.

Note that when the upward cursor movement key 3C is operated with the index 6a on the first line of the screen 8 as shown in FIG.
The PU 11 determines that the cursor 6a is on the first line, invalidates the on signal of the cursor key 30, and causes the cursor 6a and index 6b to remain at that position without moving.

At this time, the CPU 11 determines whether the text displayed on the first line is based on the character data on the first line of the first page of the document memory 19. When determining that the character data is the first line of the first page, CPtJll does not scroll down the text displayed on the screen 8 by one line, and the characters displayed on the liquid crystal display 5 at that time The column and cursor 5a are not moved.

On the other hand, if the text displayed on the screen 8 is, for example, page 2 or later, the CPU 11 scrolls the text displayed on the screen 8 down one line and stores the memory area corresponding to the 25th line on the previous page. Display the contents of the character data stored in screen 8.
Displayed on the first line of

Based on this scrolling, the character group distinguished from other characters by the index 6b and the character indicated by the cursor 6a become the character group and characters newly displayed by the scrolling, and the CPU 11 selects the characters surrounded by the new index 6b. In addition to displaying a group of characters on the liquid crystal display 5, the cursor 5
Position a at the corresponding character.

Similarly, when the downward cursor movement key 3d is operated while the indicator 6a is on the bottom line of the screen 8 (the 25th line in this embodiment) as shown in FIG. 6b is not moved at that position.

In this case, if the document data of the next page to be displayed after the 25th line of screen B is still stored in the document memory 19, the text on the screen 8 is scrolled up one line to the next page - the 21st line. The content of the character data stored in the storage area corresponding to is displayed on the 25th line of screen 8. and,
Based on this scrolling, the character group distinguished from other characters by the index 6b and the character indicated by the cursor 6a become the character group and characters newly displayed by the scrolling, and the CPU 11 selects the characters surrounded by the new index 6b. In addition to displaying a group of characters on the liquid crystal display 5, the cursor 5
Position a at the corresponding character.

As described above, in this embodiment, the 12 character strings displayed on the liquid crystal display 5 and the character group indicated by the index 6b on the screen 8 of the large display device 6 correspond to each other. The cursor 5a displayed on the device 5 and the cursor 6a displayed on the large display device 6a always correspond to each other, so when compiling the sentences you have created, it is easy to understand the sentences before and after it, making the editing work very easy. Can be done efficiently.

In the above embodiment, the resolution is [400 dots, 64 dots horizontally].
All large displays with 0 dots! 6 was used, but the so-called AV resolution is 192 dots vertically and 640 dots horizontally.
It may also be implemented using pre-vision or so-called home television vision having a resolution of 192 dots in the vertical direction and 256 dots in the horizontal direction. In this case, one character requires 16 dots vertically and 16 dots horizontally, so in the case of the AV television, the maximum number of dots is 16 dots.
In the case of a home television, only 12 rows and 16 digits can be displayed.

When one page has 25 rows and 40 columns as in the above embodiment, the CPU 1
1 reads only the displayable character data group out of the character data group for one page stored in the text memory 19 and displays it on the television. Therefore, A
In the case of a V television, characters in a range of 12 lines and 20 digits are displayed, and in the case of a home television, characters in a range of 12 columns and 16 digits are displayed.

For characters that are not displayed, the CPU 11
are cursor movement keys 3a to 3d provided on the keyboard 3
Based on this operation, the range to be read out from the character data group for one page of the document memory 19 is moved, and the character group in the part that is not displayed is displayed.

Further, in the case of a television in which the number of displayed characters is limited to a certain extent as described above, the CPU 11 may change the characters etc. to marks such as circles and triangles and display them on the television.

In other words, the character display of the mark is 16 dots vertically and 16 dots horizontally.
Since it can be displayed using a much smaller number of dots than dots required, actual characters, etc. are not displayed on the screen, but each character, etc. for one page is displayed as a mark. Therefore, the 12 character strings displayed on the liquid crystal display 5 and the index 6b are displayed on the screen 8 of the large display device 6.
It is particularly effective to make the groups of marks indicated by the mark correspond to each other, and to always make the cursor 5a of the liquid crystal display 5 correspond to the cursor 6a of the large-sized display device 6a.

Further, in the above embodiment, the indicator 6b is shaped like a rectangular frame, but the point is that it may be any other character as long as it can be distinguished from other character groups.For example, it can be displayed in reverse, underlined, or in color It is of course possible to implement this by changing the color.

(Effects of the Invention) As detailed above, according to the present invention, since the character string displayed on the liquid crystal display corresponds to the character group indicated by the index on the screen of the large display device, Wardrobe with large display device? This device combines the excellent characteristics of a Tsusa and the excellent characteristics of a word processor equipped with a liquid crystal display, and when editing a created sentence, it is easy to understand the sentence after 7yi, and the editing work can be performed very efficiently.
