DETAILED DESCRIPTION OF THE INVENTION Title of invention   Screen display type key input device Technical field   The present invention relates to an input device used in the field of a character input device or an input method. For details, see a small electronic organizer, a small word processor (word processor) and a personal computer. Key (soft key) is displayed on the screen of the Touch the screen directly with a pen or fingertip, or on the screen using a mouse or tablet. Point to the key with the displayed pointer and enter characters or symbols displayed on the key. The present invention relates to a screen display type key input device. Background art   Personal computers and word processors are generally used as information devices. The miniaturization has been rapidly promoted while increasing the size. That is, from the desktop The notebook has been shifted from the notebook type to the sub-note type. I'm stepping on it. That is, there is a limit to miniaturization using the traditional keyboard format. This is because simply reducing the size of the key impairs usability.   Therefore, the size is reduced to B5 or B6 size or less, which is used for corporate sales tools. Portable personal computers, electronic organizers, personal digital assistants (PDAs), etc. Give up on "key input" that is difficult to read, and change the screen to "pen" or "fingertip", especially "pen The transition to “touch screen input”, in which touch input is performed using -Dressing is progressing.   On the other hand, in recent years personal computers, OS (operating system), various software With the advancement of functions, desktop and notebook PCs are displayed on the screen. GUI (graphical user interface) for selecting and inputting icons with a mouse Interface) has become common, and input methods that do not use a keyboard have become widespread. ing.   However, current mouse input and pen input directly access the display screen It is suitable for selecting and inputting "menu" and "command" displayed on the screen. However, it is not always suitable for character input that is most important for word processing and e-mail. There was a problem that was not.   For example, handwriting input of characters used in the pen input type has difficulty with keyboard input. Although it is convenient for those who can use it, the recognition rate of handwriting input is not necessarily Is not high, and after recognizing, it must be converted to Kanji, Katakana, Hiragana, etc. In other words, it must go through the steps of “handwriting input” → “recognition” → “conversion” Input operation is troublesome and time consuming. There was no problem.   Therefore, a "character input board" similar to a keyboard on the screen, that is, a general keyboard Small key (soft key) displayed on the screen instead of the key (hard key) And a method of touching this key with a pen or mouse to enter characters etc. is adopted. Have been.   However, the conventional “character input board” retains the shape of the conventional keyboard. Because it is inherited, the problem that the soft keys are densely dense and difficult to touch there were.   That is, as a conventional “character input board”, a screen as shown in FIG. "QWERTY arrangement" and "Kana character arrangement" for kana character input as shown in FIG. Had adopted.

This will be described with reference to FIG.   FIG. 4 is a block diagram of an internal configuration for realizing the screen display type key input device 1, FIG. 5 is a flowchart showing the processing procedure.   The screen display type key input device 1 includes a key input unit 71 and a selection processing unit 72. The selection processing means 72 includes a determination means 73 and a character generation means 74. I have.   As described above, the key input unit 71 in the present embodiment The main key area 20 is provided with a touch (Step 1, hereafter “Step” is replaced by “S”) Abbreviated).   Here, if there is a touch input, the touch input Touch input, that is, while the pen 15 is touching a key, the key Moving or the point touch input, that is, the moving distance of the pen 15 is a predetermined length It is determined whether the length is shorter (S2).   Here, if it is determined that the input is a point touch input, the character generation unit 74 outputs Standard processing for generating the first character code set at the left position of the selected key (S3).   On the other hand, if it is determined that the input is a bar touch input instead of a point touch input, a character is generated. The means 74 generates a second character code set at the right position of the touched key. A shift process is performed (S4).   The result processed by the character generation means 74 is displayed on the liquid crystal screen 3.   With the above, the processing for each touch input is completed, and if there is the next touch input, The above processing is repeated to sequentially perform touch input. The Japanese sequence shown in Fig. 2 was used. When inputting characters, the entered alphabet is displayed on the screen display type key input device 1. Is recognized as a Roman character input by the built-in "Kana-Kanji conversion program" "Hiragana" is displayed on the screen 3 and a conversion key (not shown) Is converted to Kanji etc.   Here, a method of determining a touch input in the determination unit 73 will be described.   As shown in FIG. 6, the determining unit 73 determines that the pen 15 touches each of the keys 21 to 35. The difference in operation at the time of operation is detected, and the left position (A in FIG. 6) and the right position of each key are detected. (B in FIG. 5) is to be determined.   FIGS. 7 and 8 show a method of determining a difference in touch operation at this time. Either method is adopted.   The method shown in FIG. 7 uses the pixels (pixels) included in the display area of each of the keys 21 to 35. ) The difference of the touch operation is determined every 76. That is, as shown in FIG. , A total of 100 cells 76 of 10 columns and 10 rows in the display area of each key 21 to 35 Is set, the determination means 73 determines that the pen 15 Within a predetermined number within the area, for example, one of the keys 21-35 in the display area, or Pixel 76 and its surrounding pixels 76 (indicated by the "+" symbol in FIG. 7). When touching the pixel 76 in the area where the ), It is determined that the input has been made by a point touch, and as shown in FIG. When the above pixel 76 is touched (touch as if a hyphen “-” bar is drawn) ), It is determined that an input has been made by a bar touch.   FIG. 7 illustrates a case where the pen 15 is moved in the horizontal direction. Is moved in the vertical or diagonal direction, or in a “∨” or “∧” shape. Even if four or more cells 76 are touched, it is determined that a bar touch input has been made. Ma The starting point of the touch input may be any position within the area of each key 21 to 35. , Even if the terminal of touch (bar) protrudes from the key area, touched within the key area It is determined whether the touch is a point touch or a bar touch based on the number of pixels.   In addition, the number of cells 76 serving as a criterion is not limited to four or more and less than four. May be set according to the number of cells 76 in the display area. For example, the number of cells 76 If 5 is set to 5 columns and 5 rows, a total of 25 cells are touched. Then, it may be determined that a bar touch has occurred.   On the other hand, the method shown in FIG. 8 depends on the distance between the start point and the end point of the touch of the pen 15. To determine the difference between touch operations. That is, the determination means 73 When the touch length of the pen 15 is shorter than the set length, It is determined that the input has been made, and the length of the touch by the pen 15 is set in advance as shown in FIG. If it is longer than the specified length, it is configured to judge that it was input by bar touch I have.   Also in this case, the moving direction of the pen 15 may be vertical or diagonal, and The direction may change in the middle like a point, that is, between the start point and the end point of the pen 15. That is, if the moving distance is equal to or longer than the predetermined length, it is determined that the input is a bar touch input.   Note that the set length serving as a criterion may be set in advance, or may be used for operation. The user may set it appropriately.   Next, effects of the present embodiment will be described.   According to the present embodiment, the first and second character codes are assigned to keys 21 to 35, respectively. So, you can set two characters (alphabet) and symbols for each key 21-35 Wear. For this reason, compared to the case where one character is set for one key as in the past, In all, the number of keys can be reduced by about half.   For example, as shown in FIG. 2, only 15 main keys 21 to 35 are provided. However, each key 21-35 has two character codes, that is, a total of 30 character codes. Can be set. Therefore, it is necessary to use Japanese alphabets and English In addition to the 26 letters of the favet, in Japanese input, punctuation marks “,”, reading marks “.”, Etc. , In English input, a comma “,” and a period “. '' And other frequently used symbols. Keys 21 to 35 can be set, enough for Japanese or English input even with a small number of keys I can respond.   For this reason, 15 pieces which are much less than the conventional QWERTY arrangement or the Japanese syllabary arrangement Roman key input and English input can be performed using the main keys 21 to 35 of The keys 21 to 35 are the same size as the keys of the conventional QWERTY layout or the Japanese syllabary layout. If displayed on the surface 3, the main key area 20, which is a key display area, can be made smaller. Therefore, the amount of movement of the pen 15 for touching the keys 21 to 35 can be reduced, thereby improving operability. can do.   Further, since the main key area 20 can be made smaller, the screen touch type input device 1 Can be reduced in size, and the display area 10 for data and the like can be enlarged. In addition, handleability and operability can be further improved.   On the other hand, the main key area 20 has a key arrangement of the conventional QWERTY arrangement or the Japanese syllabary arrangement. The size of each main key 21-35 can be reduced to the same size as the The keys 21 to 35 can be easily touched with the pen 15 or fingertips. In this case, the operability can be improved.   In addition, the punctuation mark “,” and the reading point “.” That are frequently input in Japanese and the The comma “,” and the period “. Is displayed on each key 30, 34, 35, Touch input allows for even better operability when inputting Japanese or English. Can be up.   Furthermore, the key of the QWERTY layout which has been widely used and used Because the order is set to 15 main keys 21 to 35, the QWERTY arrangement Many familiar people can easily learn the key layout of this embodiment, The surface display key input device 1 can be used immediately and easily.   In addition, the Japanese sequence shown in FIG. 2 and the English sequence shown in FIG. The arrangement of the keys matches, so switch between the Japanese sequence and the English sequence Also in this case, the key arrangement is easy to remember and the operability can be improved.   To enter the two characters and symbols displayed on the keys 21 to 35, use a pen. Whether to make a point touch input at point only by making the movement of 15 slightly different , Or to perform bar touch input that moves a predetermined length while touching You can perform two types of operations, including two characters on each key 21-35, One of the symbols, that is, one of the first and second character codes, is selected by a very simple operation. You can select and enter.   For this reason, even in the touch input using the pen 15, the shift of the conventional keyboard is performed. Two types of character input operations can be performed on one key in the same manner as Is very simple, so that the operability can be improved.   Further, the movement amount of the pen 15 regarded as the bar touch input is determined by using the input device 1. If the user can make adjustments as appropriate, the amount of movement of the pen 15 differs for each user. Can determine whether it is a bar touch input or a point touch input. In addition, the operability can be further improved.   Also, since the keys 21 to 35 of the key input area 12 are arranged apart from each other, The areas of the keys 21 to 35 are clearly divided, and touch input is performed with the pen 15 or the like. To prevent erroneous operation when inputting across two keys 21 to 35 can do. In particular, when touching the gap between the keys 21 to 35 Is set to cancel the previous touch input from the gap, Erroneous operation can be reliably prevented.   Next, a second embodiment of the present invention will be described. Each implementation described below In the embodiment, the same reference numerals are used for the same or similar components as those in the above-described embodiment.

This number of touches is Table 1 shows an example of comparison with Kana kana input and Roman character input in QWERTY array. Shown in                       Table 1 Comparison of the number of touches of pen input Note: In the Japanese syllabary array, "Daku" indicates a key, and "Small" indicates lowercase shift.   As can be seen from Table 1, the use of the high-speed arrangement shown in FIG. Because you can input with a single touch, the number of touches (table (Each number in 1) can be reduced, especially in sentences with many on-speech words. Can be increased.   Also, the high-speed array is designed so that the flow of character input moves sequentially from right to left. Have been. In other words, touch the left vowel or diphthong next to the right consonant, Next, touch the second syllable "n / ki / ku / chi / tsu / tsu" on the left. There is less waste in the movement of the camera, and operability can be improved. This is a two-syllable phonetic reading kanji In the case where the second syllable is not a vowel, one of "n / ki / ku / chi / tsu / tsu" In other words, after the first syllable (consonant + vowel), "n / ki / ku / chi / tsu / tsu" Focused on the characteristics of Japanese that are likely to be empowered, It is very effective in entering words.   Kanji including these characters include the following.   1) Example of a kanji whose second syllable is "i" (one of the double vowels "AI, UI, EI") Example)   -Held (KAI SAI)-Inside and outside (NAI GAI)   -Accounting (KAI KEI)-Analogy (RUI SUI)   ・ Estimation (SUI TEI) ・ Cumulative (RUI KEI)   2) Examples of kanji whose second syllable is "U" (such as one of the double vowels "UU ・ OU") Example of Kanji including "YUU" and "YOU"   ・ Method (HOU HOU) ・ Structure (KOU ZOU)   ・ Factory (KOU ZYOU) ・ Tokyo (TOU KYOU)   ・ Ventilation (TUU FUU) ・ Center (TYUU OU)   3) Example of Kanji whose second syllable is "n"   ・ Safe (A and ZE) ・ Easy (KA and TA)   ・ Chaos (KO TO TO)   4) Example of Kanji whose second syllable is "Ki-ku"   ・ Tired (HE comes E) ・ Exact (TE comes KA)   ・ Plan (KA Ku SA) ・ Purpose (MO Ku TE)   ・ Nemesis (SYUKU TE) ・ Immediate (SOKU SE)   5) Examples of Kanji characters whose second syllable is "chi-tsu-tsu"   ・ One day (I-chi NI) ・ Yoshi-day (KI-chi ZI)   ・ Quality (SI and ZI) ・ Kiri (SE and ZI)   ・ One day (I Chi NI Chi) ・ Active (KA Tsu PA)   ・ Real (ZI-SI) ・ Departure (SYU-PA)   Next, the QWERTY type English that can be switched by the selection menu key 18 shown in FIG.

FIG. 32 is a flowchart showing the processing procedure.   The screen display type key input device 101 includes an input control unit 170, a shift input unit 171 , A processing control unit 172, and an output control unit 176.   The input control unit 170 includes a selection menu 11, a main key area 20, a switching key In the rear 40 and the function key area 50, it is determined whether there is a touch input by the pen 15. (Step 1, hereinafter, “step” is abbreviated as “S”).   If there is a touch input, the shift input unit 171 determines that the touch input is a shift input. It is determined whether or not there is (S2).   Here, if it is determined that the input is a shift input, the shift input unit 171 performs a touch operation. A shift process is performed to generate a key code at the shifted position of the selected key (S3). Is sent to the processing control unit 172. On the other hand, it is determined that it is not a shift input For example, the shift input means 171 generates the key code of the non-shift position of the touched key. And sends it to the processing control unit 172.   The processing control unit 172 includes an array switching unit 173, a key processing unit 174, a function processing Means 175 are provided, and each processing means is provided in accordance with an input key. Is selected and an input process is performed (S4). For example, if the entered key is Menu key 16 to 19 of the menu 11 or each switch key area 40 If the replacement keys 41 to 43 are specified by the The main key area 20, the switching key area 40, and the function key area 50 A replacement process is performed.   If the input key is each key in the main key area 20, the key processing operation is performed. The process of displaying and outputting the key on the input line 60 is performed by the step 174 ( S4). At this time, in the case of inputting a Roman character such as a standard arrangement, the key processing unit 174 The input alphabet is automatically converted to kana (S4).   Furthermore, if the input key is each key in the function key area 50, the function processing The function set to the key is executed by the step 175 (S4). For example, conversion When the key 51 is touched, the character string displayed on the input line 60 is converted into kanji. To confirm. When the execution key 54 is touched, the determined character string is displayed in the display area. A process for displaying in the area 10 is performed.   The output control unit 176 displays the result processed by the processing control unit 172 on the liquid crystal screen 3. A display process is performed (S5).   With the above, the processing for each touch input is completed, and if there is the next touch input, The above processing is repeated to sequentially perform touch input.   As shown in FIG. 33, the shift input means 171 is a push-button type Shift input means 181, click-type shift input means 182, pre-shift type shift input Force input means 183 and the area shift type shift input means 184. It is selected and used as appropriate.   Hereinafter, each shift input means 171 will be described individually.   The push-button type shift input means 181 presses the push button 4 shown in FIG. When a key is touched with the pen 15, the shift state of the key is set. Generate the code of the symbol (second character code), and press the button 4 When the key is touched in the state, the symbol set to the non-shift state of the key is displayed. It is configured to generate a code (first character code).   The click-type shift input means 182 allows the key to be touched twice with the pen 15 within a predetermined time. When the key is touched, the code of the symbol set in the shift state of the key (the second character Code), and if it is touched once within a predetermined time, the key is not shifted And configured to generate a code (first character code) of the symbol set in the state. ing.   That is, as shown in FIG. 34, the screen is first touched with the pen 15 and then twice. If the time between touching and releasing the eye is within the set time (,), shift When the state is determined and the touch operation with the pen 15 is performed once within the set time (,) If the second touch operation exceeds the set time (), it is determined that the game is not shifted. It is configured to disconnect.   The shift key 5 shown in FIG. When the input mode is set to the shift state, the key touched by the pen 15 A code (second character code) of the symbol set in the shift state of When the input key 5 is pressed again and the input mode is set to the non-shift state, The code of the symbol set to the non-shifted state of the key touched by the pen 15 (first code Character code).   As shown in FIG. 35, the area-division-type shift input means 184 is provided in the upper half of each key. Is divided into the shift region 184A and the lower half is divided into the non-shift region 184B. Touch area to determine which area 184A, 184B was touched in The touch area determining means 187 includes a shift area 184A. If it is determined that the key has been shifted, (A second character code), and the touch area determination unit 187 generates the non-shift area 1 If it is determined that 84B has been touched, the key is set to the non-shift state. It is configured to generate a code (first character code) of the symbol.   In addition, this area division may be divided into right and left without dividing the key up and down, It may be divided diagonally, but in any case, touching each area in that area It is preferable to display a symbol to be input at this time.   Further, as the shift input means 171, the push button type shift input means 1 described above is used. 81, click-type shift input means 182, pre-shift type shift input means 183, Any one of the area segmentation type shift input means 184 may be set. The shift input means 171 is set so that the user can appropriately select it. You may.   Note that the push button 4 and the shift key 5 are pressed as shift input means 171. When not using the button-type shift input means 181 and the pre-shift input means 183 Need not be provided on the main body 2.   Further, when the high-speed arrangement shown in FIG. And the second two shift states (second and third character codes) are set. Therefore, the shift input unit 171 also uses the first and second different types 2 It is necessary to set two shift input means.   For example, a push button type shift input unit 181 is set as the first shift input unit. Then, if the click-type shift input means 182 or the like is set as the second shift input means, Good. In this case, for example, touch keys 33 and 34 while pressing button 4 In this case, the punctuation mark “,” and the reading point “” in the first shift state (second character code). ”Is input, and click the keys 33 and 34 (click the key twice within a certain time). ) In the second shift state (third character code). , “V” are input.   Next, effects of the present embodiment will be described.   According to the present embodiment, only 15 main keys 21 to 35 are provided. However, at least two keys are assigned to each of the keys 21 to 35 by the shift input means 171. (Key set to shift state and key set to non-shift state) And the second character code can be set, and set at least 30 keys in total be able to. Therefore, the alphabet used when inputting Japanese romaji, In other words, vowels "A", "I", "U", "E", "O" and vowel key combination "K", "S", "T" to input the clear tone from "ka" line to "wa" line in Japanese , "N", "H", "M", "Y", "R", "W", combined with vowels "G", "Z", "D", "P", "B" Each main key 21 can include a period character “,”, a reading character “.”, Etc. in addition to 19 characters. It can be set to ~ 35, and it can sufficiently respond to Japanese input even with a small number of keys.   Similarly, in addition to the 26 letters of the alphabet, a comma “,” and a period “. Etc. It can be set to the main keys 21 to 35, and it can sufficiently respond to English input.   Therefore, compared with the conventional QWERTY arrangement and the Japanese syllabary arrangement, there are 15 Roman key input and English input can be performed using the main keys 21 to 35. This Therefore, each key 21-35 is the same as the key of the conventional QWERTY arrangement or the Japanese syllabary arrangement If the size is displayed on the screen 3, the main key area 20 which is a key display area is small. Can move the pen 15 that touches the keys 21 to 35 can be reduced. Workability can be improved.   Further, since the main key area 20 can be made smaller, the screen touch type input device 1 Can be reduced in size, and the display area 10 for data and the like can be enlarged. In addition, handling and operability can be improved.   On the other hand, the main key area 20 has a key arrangement of the conventional QWERTY arrangement or the Japanese syllabary arrangement. The size of each main key 21-35 can be reduced to the same size as the The keys 21 to 35 can be easily touched with the pen 15 or fingertips. In this case, the operability can be improved.   In the present embodiment, switching keys 41 to 43 and selection menu 11 are used. Menu keys 16 to 19 and array switching means 173 are provided, The arrangement of -21 to 35 can be switched to seven types. For this reason, Alphabe Not only numbers, symbols and even arrays similar to the traditional QWERTY array Any of various key layouts can be set.   Therefore, the arrangement of the character codes set in the main keys 21 to 35 is -For character input (standard arrangement), English arrangement, number arrangement, symbol arrangement, high-speed arrangement, QWE It is possible to switch to 7 types of RTY English only sequence and QWERTY Japanese only sequence Even if there are only 15 main keys 21 to 35, the shift input And the array switching means 173, 30 keys x the number of arrays Can be set, and each symbol (letter, numeral, symbol, etc.) can be easily input.   Further, switching of each array is performed by switching keys 41 to 43 and menu keys 16 to 1. Since you only need to touch 9, you can easily switch the arrangement of each main key 21-35 In addition to Roman alphabet input, English, numbers and various symbols can be easily input it can.   In addition, each array switching means 173 includes not only main keys 21 to 35 but also function keys. The function keys 51 to 56 displayed in the area 50 are also configured to be switched. So that function keys 51 to 56 can be set according to each arrangement. Can be further improved. For example, "Kanji conversion ”And other functions are not displayed in the English layout so that only necessary function keys are displayed. Can be displayed, and the operability is further improved.   In the arrangement for inputting Roman characters shown in FIGS. 23 and 28, keys and consonants of vowel parts The partial keys are arranged separately in the vowel area 20A and the consonant area 20B. Therefore, when inputting Japanese Roman characters in which consonants and vowels appear alternately, The position of the vowel key can be easily grasped, and the operability can be improved.   In addition, clear consonants, which are frequently used among consonants, are placed in the non-shifted state of each key (No. 1 character code), so when inputting frequently Since no work is involved, operability can be improved in this respect as well.   In addition, the keys 27, 28 near the center of the main key area 20 have vowels and Set the “A” and “K” keys that are frequently used in consonants, and In the past, the vowels "A", "I", "U", "E", "O" and And consonants "K", "S", "T", "N", "H", "M", "Y", "R", Since the “W”, that is, the “ka” line to the “wa” line are arranged in order, The rows can be easily grasped, and the operability can be further improved.   Further, each of the consonant areas “K”, “S”, “T”, “N”, “H” In the shift state (second character code), vowels "A", "I", "U", "E", Enter “G”, “Z”, “D” to input Japanese voiced sounds and semi-voiced sounds in combination with “O”. , "P" and "B" are arranged, so they correspond to the input positions of "ka", "sa" and "ta". Then, “が”, “Za”, “Da”, “ぱ”, "Ba" will be arranged respectively, making it easier to remember the key position of the voiced sound and semi-voiced sound And the operability can be further improved.   Standard arrangement for inputting Roman characters (Fig. 23), high-speed arrangement (Fig. 28) and QWERT In the Y-type Japanese-only array (FIG. 29), the frequently used sound-repellent "n" The sound "tsu", the period ",", the reading ".", And the long sound "-" are also the main keys 21-35. Because it is partially set, even with a small number of keys, Full punctuation marks “,”, reading marks “.” And long sounds “-” can be entered with a single touch operation, improving operability. Can be improved. In particular, the sound repelling “n” is not transmitted to the key 31 or the key 35. Is set in the default state, so it is frequently used in Japanese input, especially in Onyomi Kanji etc. You can easily input the sound-repelling "n".   On the other hand, when the main key is set for the English sequence (FIGS. 25 and 29) However, the comma "," and the period "." Shift each key State or non-shifted state, allowing direct touch input Also, the operability at the time of inputting English can be improved.   Furthermore, the arrangement of many keys in the English layout of FIG. 25 matches that of the standard layout of FIG. The QWERTY type English-only array in FIG. 29 is the QWERTY type Japan in FIG. Because the key layout matches many key layouts, the standard layout and the English layout are switched. Even when switching and using together, the key layout is easy to remember and operability can be improved. Wear.   In the numeric arrangement shown in FIG. 26, each numeral is the same as a numeric keypad on a conventional keyboard. Can be arranged in the same way, and because various symbols used for calculation can be input by touch, Input and calculation operations can be performed easily.   In the symbol array shown in FIG. Number can be displayed on each of the main keys 21 to 35 and touch input can be performed. The seed symbol can be easily entered. In addition, each parenthesis is placed in two columns on the reference side. Shift state of the arranged six main keys 21, 22, 26, 27, 31, 32 And non-shifted state, so parentheses and other symbols Key position can be easily determined, and input operability can be improved.   In the high-speed arrangement shown in FIG. 28, each of the keys 21, 22, 26, 2 in the vowel area 20A 7, 31, 32 shift state (second character code) , "AI", "UI", "UU", "E" "I", "OU" and "YUU", and these characters can be input with one touch. As a result, the input efficiency of Japanese can be improved.   In addition, in the high-speed arrangement, keys 41, 42, 43 used as normal switching keys In the shift state and non-shift state, “tsu”, “ku”, prompting sound “tsu”, “chi”, “ Key for inputting “K” and “YOU”. "Ki-ku-chi-tsu-tsu" that appears frequently in the second syllable of Kanji can be entered with a single touch Also, the letter "YOU" with diphthong like Tokyo (T0U KYOU) Input can be performed by touch, and input efficiency can be further improved.   Furthermore, these keys take advantage of the fact that they appear frequently in the second syllable, -After any key of the area 20 is touched, the setting of the switching keys 41 to 43 is performed. To "ki / ku / chi / tsu / tsu" etc., usually the same switching keys 41 to 41 as the other arrangements Since the keys are used for setting 43, the keys 41 to 43 are appropriately switched according to the situation.
