Abstract

PURPOSE:To facilitate key operations by selecting one out of 'a', 'Ka', 'sa',... in accordance with depression of a key A, K, S or the like and using a key, which designates the position from the first consonant or the alike in each series, and a repeat key to input a desired KANA (Japanese syllabary) character. CONSTITUTION:A key to which an English character A, K, S, T, N, M, Y, R, or W is added is depressed to input the KANA character corresponding to the first vowel or consonant in the a, k, s, t, n, h, m, y, r, or w series. The position from the first vowel or consonant in the a, k, s, t, n, h, m, y, r, or w series is designated by the number of times of depression of search keys, on which numerics 6 and 4 are displayed, to input a desired KANA character. If the repeat key on which numeric 5 is displayed is depressed, the just preceding KANA character code held in a KANA output code holding means is repeatedly outputted through the same character output means.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a kana input method from a keyboard used in the technical field of information processing.

2. Description of the Related Art Conventionally, a common method for inputting kana characters into an information processing Wff is to use a keyboard having a group of kana character display keys arranged in a JIS layout.

Also, small keyboards with fewer keys are being used.

Problems to be Solved by the Invention Among the above-mentioned conventional kana character input methods, those that use a JIS layout keyboard have a key layout for kana characters determined based on their frequency of use.

For this reason, it is not in the so-called "aiweo" order,
Even if a user tries to memorize such an irregular key arrangement, it takes a considerable amount of time, and there is a problem in that it takes a long time to search for keys, especially for characters that are used less frequently.

In addition, small keyboards have a small number of keys and cannot be arranged in JIS or 50-syllabary layouts, so each model often has an even more irregular key layout, and it takes a considerable amount of time for users to memorize the key layout. I need. Another problem is that even if you memorize the key layout for one model, that knowledge is hardly applicable to other models.

Means for Solving the Problem The kana character input method of the present invention includes a group of keys on which alphanumeric characters are displayed, and a designation of whether the character to be input by operating these key groups is alphanumeric or kana. The keyboard is equipped with an input character type specification key.

Furthermore, in the kana character input method of the present invention, A, ni, S, and T are specified under the input character type of kana.

Based on the operation of the keys on which the alphanumeric characters N, H, M, Y, R, and W are displayed, A, Power, Su, Yu, Su in the same order.

One of the vowels or consonants in the A column of each line such as Ha, Ma, Ya, U, Wa is selected, and the step from the vowel or consonant in the A column in each line is specified based on the number of subsequent presses of a predetermined key. , the most recently inputted character that is currently being saved can be input repeatedly based on a predetermined command.

Hereinafter, the effects of the present invention will be explained in detail along with examples.

Embodiment FIG. 1 is a block diagram showing the configuration of a keyboard, a keyboard interface circuit, and a processing device to which an embodiment of the present invention is applied.

In FIG. 1, 11 is a keyboard having a group of keys displaying alphanumeric characters, and 12 is an input mode for selecting an input mode for receiving an input signal 110 from this keyboard 11 as an alphanumeric code or as a kana character code. It is a means of selection. The input signal 110 from the keyboard 11 is output as an alphanumeric code on the output line 120 if the input mode selection means 12 is selecting the alphanumeric input mode, and is output as a hakana code if the input mode of the kana character mode is selected. It is output onto the output line 121 as a target for conversion into a character code.

13 is a control code passing means for passing the control code; 1
Reference numeral 4 denotes a read address generating means for generating a corresponding kana character code from the alphanumeric code outputted on the output line 121, and 15 operates upon detecting that a functional character of a predetermined search key appears on the output line 121. 16 is a kana character code storage means, and 17 is a kana character code holding means for holding the output signal 160 of the kana character code storage means 16.

Furthermore, 18 is a kana character search means for searching for the final input kana character based on the output signal 170 and the output signal 150 (r+IJ search signal) or 151 (r-IJ search signal) of the functional character detection means 15; This is a cursor left movement generating means that generates a cursor left movement code based on the output signal 180.

Reference numeral 21 denotes a same character output means for repeatedly outputting the immediately preceding input character in accordance with the repeat signal 152 from the functional character detection means 15, and 22 a kana output unit which retains the previously input kana character and supplies it to the same character output means 21. It is a code holding means.

20 is a logical addition means, which outputs an alphanumeric code 120 when the alphanumeric mode is selected, a kana character code output 160 when the kana character mode is selected, an output 181 of the kana character search means 18, and a cursor left movement code output 190. , control code output 130 and output 210 of the same character output means 21
A logical OR is created and output as output 200. The output 200 of the OR means 20 is supplied via the bus control section 34 to a host processor comprising a central processing section 31, a main storage section 32, and a display section 33. The host processor processes this to display the corresponding alphanumeric characters and kana characters on the display section 33.

As shown in the plan view of FIG. 2, the keyboard 11 shown in FIG. 1 is composed of a group of keys on which alphanumeric characters are displayed and an arrangement of various function keys.

To input kana characters from the keyboard 11, first select the kana input mode by pressing the function key "kana". Next, as shown in the correspondence table in Figure 3, A, S, T
, N, H, ~i, Y, R, W are pressed in the same order: A, Power, Su, Yu, Su, Ha, Ma,
Enter the kana characters for the vowels or consonants in the A-dan such as ya, u3 wa. Subsequently, desired kana characters are input by specifying the level difference from the A column in each line by the number of times the search key on which the numbers "6" and "4" are displayed is pressed.

As shown in Figure 3, there are two types of search keys for the above search key: "+1" and "-1", and based on the number of times these keys are pressed, "I" and "Tsu" in each row are selected. , "1-dan" and "o-dan" can be specified.

Further, by pressing down the repeat key on which the number "5" is displayed, the immediately preceding kana character code held in the kana output code holding means 22 is repeatedly outputted via the same character output means 21.

Figure 4 shows kana characters and kana character code (JIS code)
Figure 5 shows the correspondence between alphanumeric characters and alphanumeric codes (
The correspondence relationship with JIS code) and the correspondence relationship between the stored contents of the kana character code storage means 16 and addresses are shown.

In Figure 6, the kana character "Ha" is entered by pressing the alphanumeric key on which rHJ is displayed, and then the final character is entered by pressing the search key "+1" or by pressing r-IJ. In this case, the table shows the correspondence between the number of times each search key is pressed and the characters that are finally input.

Taking the case of FIG. 6 as an example, the operation of the circuit of FIG. 1 will be explained.

When the key on which "11" is displayed is pressed while the input mode selection means 12 selects the kana character mode, input signal force lines 110 and 12 from the keyboard 11 are pressed.
1, "IJ" is input to the address generating means 14. The JIS code of this rHJ is "72", and based on this, in order to read the kana character "ha" stored at address "40" in the kana character code storage means 16, the read address generation means 14 uses "72". ”Accesses the built-in ROM in which data “40” is stored at address.

As a result, the content "202" (kana character "ha") is read from the address "40" of the kana character code storage means 16, and this is sent to the host processor via the logical sum means 20 and the bus iii control section 34. is displayed on the display section 33.
"Ha" is displayed on -d. At the same time, the kana character code "202" is successively outputted from the kana character code storage means 16.
is held in the kana character code holding means 17.

Next, when the number key "6" on the keyboard 11 is pressed, the function character detection means 15 detects that it is the search key "+1" via the input lines 110 and 121, and the function character detection means 15 outputs Line 150 is turned on. As a result, the kana character search means 18 increments the search counter by 1 and creates a kana character code "203" by adding it to the content "202" of the kana character code holding means 17. The kana character search means 18 determines whether the newly created kana character code is valid or not, and if it is valid, turns on the search valid signal 180.

The cursor left movement code generation means 19 generates a cursor left movement code when the search valid signal 180 is turned on, and sends it to the host processor via the OR means 20 and the bus control section 34.

As a result, the cursor on the display section 33 of the host processor moves to the left by one position, and returns to the position where the kana character "ha" is displayed through the procedure described above.

In parallel with this, the kana character search means 18 outputs the kana character code "203" onto the output signal line 181.
This is sent to the host processor via the logical sum means 20 and the bus control unit 34, and is displayed at the cursor position on the display unit 33.
``Hi'' is displayed instead of ``Ha''.

Similarly, each time the number key "6" is pressed, the search counter of the kana character search means 18 changes to "2" and "3".
, 4'', 40'', 1'', etc., and the cursor position returns to the original position, so that the cursor position on the display unit 33 is displayed as "F", "Go", "H". ”, “ha”, “hi”, etc., kana characters are input and displayed in a cyclical manner.

On the other hand, when the numerical key "4j" is pressed following the pressing of the alphabetic key on which rHJ is displayed, this is detected as "-1" by the function character detection means z5 via the input signal lines 110 and 121. is detected as the search key, and its output signal line 151 is turned on. Accordingly, the content of the search counter in the kana character search means 18 changes from "0" to "4", and "ho" is displayed in place of "ha" on the display block 33 of the host processor. Similarly, press the number key "4" on the keyboard 11.
Each time is pressed down, the search counter of the kana character search means 18 changes to "3" and "2".

The characters at the cursor position on the display unit 33 change cyclically in the reverse direction, such as "1", "0°,""4", etc. "Ha", "Ho", etc. are entered and displayed in a cyclical manner.

In this manner, the operator of the keyboard 11 can input desired kana characters by pressing the search key while checking the kana characters displayed at the cursor position on the display section 33.

Furthermore, when the key on which the number "5" is displayed is pressed when the kana input mode is selected, the functional character detection means 15 detects that it is a repeat key, and the output signal line 152 is turned on. . As a result, the same character output means 21 is activated, and the immediately preceding kana character code held in the kana output code holding means 22 is continuously supplied to the host processor.

In this embodiment, the numeric keys "6" and "r+1" and "-1" are used as search keys and repeat keys, respectively.
Although the configuration in which keys 4 and 5 are assigned is illustrated, any other suitable key may be used.

Effects of the Invention As explained in detail above, the kana input method of the present invention has the following effects:
Keys A, S, where alphanumeric characters are displayed.

Based on the pressing of T, N..., A, Force, S are applied in the same order.

Input the desired kana character by selecting one of the A consonants, etc. in each line of Yu, Su, etc., and specifying the level difference from the A consonant, etc. by successively pressing a predetermined key number of times. Because of its structure, there is a regularity in the correspondence between kana characters and the alphabetic keys used to input them, which makes key operations easier, and has the advantage that it can be applied to any model as long as alphanumeric keys are used. be.

In addition, the kana manual system of the present invention is configured to retain the previously input character and input it repeatedly based on the repeat function designation, which improves efficiency when inputting the same kana character continuously. There is a point.
