Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention facilitates the input of a number of character types into input devices for word processors, personal computers, workstations, and computer terminals, especially various keyboards. The present invention relates to a mode-setting type symbol string input method.

[Background of the invention]

The conventional input mode setting mechanism is IIITACT-560
As shown in the /20 video data system operating manual, etc.
This will be effective for the key press operation that you are about to perform and the kana-kanji conversion. In addition, the input mode conversion only corresponds to other fixed characters for the same key. However, it does not only convert an input string to another string, or convert one character to one character.
There was nothing that did string-to-string conversion, including converting multiple characters to one character and one character to multiple characters.

In addition, there is no mode conversion mechanism that can perform input mode conversion from one character to multiple character strings, or from a symbol string to another symbol string, or even multiple waves like other symbol strings. Ta.

[Purpose of the invention]

An object of the present invention is to solve the above-mentioned problems, and to provide input devices such as keyboards with various modes (alphabetic, Roman, katakana, hiragana, uppercase, lowercase, double-width,
It is an object of the present invention to provide a mode setting type symbol string input method that eliminates the need to re-input the mode change part when setting errors or changes (half-width, etc.) and enables multi-stage mode conversion.

[Summary of the Invention] In order to be able to reset the character type of a character string once input in a keyboard input device, etc., the latest input character examples that remain in temporary memory, as well as those stored in main memory or storage storage device, are stored. A specification section is provided for resetting the character type specification mode for a character string and performing character type conversion accordingly. Character type conversion is not limited to one character to one character, but it is also possible to check what kind of character string the input character string or symbol string corresponds to in the changed character type or symbol mode, and also perform multi-stage mode conversion. It is also possible to input by Make the appropriate conversion.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. In the keyboard input table @1, general character input keys and mode setting keys (mode setting device) 2, 3, 4, 5
．． 6 Conversion key 8 No conversion and conversion cancellation key 9. In addition to the cursor movement keys 10, 11, 1, 2 and 13, a mode change key 7 is provided as a mode setting toilet change indicator. The mode setting key is Romaji/Kana mode setting key 2.
, Upper case/lower case alphabet mode setting key 3. Half-width/full-width mode setting key 4. Alphanumeric/kana mode setting key 5. There are 6 Katakana/Hiragana mode setting keys. When a key input is performed, the input signal is converted by the processor 14 into a character code string that matches the setting state of the mode setting keys at that time, and is stored in the temporary storage device 19. In this state, when the conversion key 8 is pressed, the character code string in the temporary storage device 19 is subjected to kana-kanji conversion processing, and the main storage device y! i21 or storage storage device 22, and when the non-conversion key 9 is pressed, the character code string in the temporary storage device 19 is stored in 21 or 22 without being subjected to conversion processing.

Although the above points are the same as those of the conventional input device, the functions of the mode change key 7 and the code converter 23 newly provided in the present invention will be explained below in accordance with the embodiment shown in FIG. In this example, the mode setting keys 2, 3, 4, and 5.6 are respectively set to Romaji-kana conversion mode or Kana direct input mode, uppercase alphabet mode or lowercase alphabet mode, half-width mode to full-width mode, and alphanumeric mode. You can choose between Kana mode, Katakana mode, or Hiragana mode. In the following explanation, any of these modes will be denoted by the symbols P+ q+ r...,
It will be represented by S. When the mode is set to P, by sequentially pressing the general character keys (FIG. 2, steps 101 and 102), the string a1 of the character code of mode P is selected. az...an is temporary memory 1
9 in the order in which they are pressed. temporary memory 1
9 includes a start pointer 15, an end pointer, a secondary input pointer 17°, and a temporary buffer 18. When one character code is input, the values of the primary input pointer 17 and end pointer 18 are advanced by one (step 103°105
) The input character code ct, 1≦i≦n, is stored at the position pointed to by the next input pointer in the temporary buffer (step 1
04).

Temporary buffer 18 has character code strings C1, C2...Cn

The character code string d, c(z...l is moved to the main memory buffer 20 as dll (step 115)) When the non-conversion key is pressed instead of the conversion key (step 118)
. Temporary buffer 18 character code string CI, cz...
, Cn are moved to the main memory buffer 20 as they are without being converted. When the length of the string in main memory buffer 20 exceeds a certain threshold, its contents are moved to storage storage 22 and the main memory buffer is emptied. When the conversion key 8 or non-conversion key 9 is pressed, the start pointer and end pointer of the temporary memory are reset to the state (zero) when starting to input a new character string, but (steps 116 and 11)
7) The value of the end pointer is left unchanged in preparation for a mode change.

The character code string Cx, C in the mode is stored in the temporary buffer 18.

12), the value of the next input pointer 17 is set equal to the value of the end pointer 16; (Step 112). The subsequent operation proceeds in the manner described up to this point. That is, when a general character is input, the next input pointer 17 is advanced by one, and the input character is placed in the position indicated by the next input pointer 17 in the temporary buffer 18 as a mode q character code. Similarly, when the conversion key 8 or the non-conversion key 9 is pressed, the first pointer 15 and the last pointer 1 of the temporary buffer 18 are
The character code string indicated by 6 is transferred to the main memory buffer 20 (after kana-kanji conversion in the case of the conversion key) 6 Press mode change key 7 again and press mode setting key 2

The functions of the keys not explained above are the same as those in conventional keyboard input devices (Step 1
19) To show a concrete example of conversion, we will now use the temporary buffer 18
Assume that a character code string "pen" is contained in the full-width mode of the lowercase alphabetic character mode.

At this time, if the mode change key 7 is pressed and the uppercase alphabet mode is set, the pen is converted to PEN in the uppercase English double-width mode. In this state, press the mode change key 7 again and set it to Romaji mode or Katakana mode.
PEN is converted to pen.

By pressing the conversion key 8 or the non-conversion key 9.

To redo the mode setting of the character strings CI, Cx...Cn stored in the main memory buffer 20 or storage storage device 22, press the cursor movement keys 10, 11, 12°13.

The character code string Cn is entered into the temporary buffer 18, and the head pointer 15 is set to point to the first character C1.
The end pointer 16 and next input pointer 17 are set to point to the last characters C and l. After this, when the mode change key 7 is pressed and one of the mode setting keys 2, 3, 4, 5.6 is pressed to set the mode to 9, the character code strings Cx, C2, etc. in the temporary buffer 18 are changed. lcn is the character code string CI', C2', ... C, l of mode q.
is converted into. In this state, when the non-conversion key 9 is pressed, the old character code string CI in the main memory buffer 20 is read.

C2-HCn is a new character code string 01', 62',...
Replaced by C1'.

Code converter 2 used in the above character code conversion
There is one code converter 3 for each possible combination of mode conversions, and the total number is a set of a plurality of code converters.

For mode conversion, various combinations are possible, such as from uppercase letters to lowercase letters, from hiragana to katakana, but there are some combinations that are meaningless, such as no kanji half-width mode.
No mode converter is provided for such meaningless conversions. The code converter that converts from mode p to mode q is the character code string C1 in mode p.

Another embodiment is shown in FIG. In this example, the shift key 207 also serves as a mode change indicator.

In addition to redoing the mode settings shown in the example of Fig. 1,
We will also redo the kana-kanji conversion. In this embodiment, the Romaji/Kana mode setting key 202 is used as the mode setting key.
．． Pressing any one of the uppercase/lowercase alphabetic character mode setting key 203, the half-width/full-width mode setting key 204, the alphanumeric/kana mode setting key 205, and the katakana/hiragana mode setting key 20B and the shift key 207 will switch to that mode. The mode will be reconverted to the mode specified by the setting key. For example, when the temporary buffer 218 contains full-width character strings such as hiragana and katakana by the same operation as in the embodiment shown in FIG.
When the shift key 207 is pressed at the same time, the code converter 223 is used to convert the katakana character string to hiragana katakana. Strings that were originally in katakana remain unchanged. If the key 204 for specifying half-width characters and the shift key 207 are pressed at the same time, the half-width character string hirakanashi #kanahachi is converted.

By the same operation as in the embodiment of FIG. 1, the main memory buffer 2
20 or the storage device 222 for storage, in the embodiment of FIG. 3, the range of the character string to be reconverted is specified using the mouse 224.

Next, an example of re-conversion of kana-kanji conversion will be described. In the embodiment shown in FIG. 3, when a hiragana character string is selected as a character string to be reconverted and the conversion key 208 is pressed, the character string is replaced with a character string converted from kana to kanji using the kana-kanji converter 225. It will be done. Similarly, if you select a kanji string and press the non-conversion key 209, the kanji-kana converter 226
is used to replace a kanji string with a hiragana string.

Also, if you select a kanji string and press the conversion key 208,
The kana-kanji converter 225 is used to convert the kanji string into another kanji string as a homophone. In this way, the conversion method can be changed without re-inputting the character string to be converted.

As described above, the present invention has an instruction means for converting an input symbol string into another symbol string. These instruction means not only convert the already input symbol strings, but also make it possible to convert the modes of these input symbol strings as shown below. It is possible to convert other combinations of symbol strings shown in . That is, (1) converting from kana mode to romaji mode (71 change m), (2) converting from romaji mode to kana mode, (3) converting from uppercase alphabet mode to lowercase alphabet mode, (4) converting from lowercase alphabet mode to English Converting to uppercase mode, (5) converting from half-width mode to full-width mode, (6) converting from full-width mode to half-width mode, (7) converting from alphanumeric mode to kana mode, (8) converting from kana mode to alphabetic mode. Conversion to number mode, (9) Conversion from katakana mode to hiragana mode, (10) Conversion from hiragana mode to katakana mode, (11) Conversion from hiragana to kanji, (
12) Conversion from Kanji to Hiragana, (13) Conversion from Katakana to Kanji, (14) Conversion from Kanji to Katakana,
(15) Conversion from arithmetic numerals to Chinese numerals, (16) Conversion from Chinese numerals to arithmetic numerals, and other conversions are provided with an instruction mechanism that performs conversions without re-executing the key hexagonal operations on the character string to be converted.

Although the above explanation is based on the keyboard, these input instructions can also be input using screen instructions using a line pen, mouse, cursor touch panel, etc. You can also enter information using the keyboard surface displayed on the touch panel screen, or give instructions using soft keys.
Various instructions can be given to the contents of a row of keys arranged around the screen using a highly diverse key input method in which the contents of the keys are displayed around the screen.

〔Effect of the invention〕

According to the present invention, there is no need for re-input operations due to forgetting to switch modes or incorrect mode settings, or re-input operations due to changing the character type after inputting, improving the efficiency of inputting symbol strings such as character strings. do. Generally, when inputting characters, the user often focuses on the document rather than the input character display device, so it is common to use multiple cross-strokes without realizing that the mode setting is incorrect.This mechanism is designed to handle such cases. very effective.

In addition, it is possible to switch input modes in a variety of ways by combining a small number of keys, etc., and it is possible to switch modes in multiple stages, and it is also possible to freely instruct one-character to multi-character conversion.
