Has been. In addition, the display 10 and the input button unit 20 are connected to the input / output port 45.

  The CPU 41 is an arithmetic unit that controls each unit connected by the bus line 46. The ROM 42 is a non-rewritable nonvolatile memory storing control programs executed by the CPU 41 (for example, flowcharts of processes shown in FIGS. 6 to 9) and characters or symbols assigned to the buttons 21 to 30 (see FIG. 1). The RAM 43 is a memory for rewritably storing a character / symbol type counter 43a and a button data memory 43b, which will be described later, when the control program is executed, and the EEPROM 44 is in a state when the power of the display device 1 is turned off. This is a rewritable nonvolatile memory for recording.

  In the ROM 42, the hiragana clear sound, hiragana murmur, hiragana prompting and roaring, hiragana half murmur, katakana clear sound, katakana murmur, katakana to be assigned to each of the buttons 21 to 30 (see FIG. 1). Ten types of data are stored, such as vowels and roars of katakana, semi-voiced katakana, half-width numbers, lower-case letters and symbols, and full-width numbers and upper-case letters and symbols. Here, the number half-width / alphabetic lower-case letter / symbol is a combination of the number half-size / alphabetic lower-case letter / symbol. Is a combination of uppercase letters and symbols.

  These ten types of data are assigned to the respective buttons 21 to 30 (see FIG. 1) of the input button unit 20 for each type as shown in FIG. Then, the characters or symbols assigned to the buttons 21 to 30 are each one character or one symbol as shown in FIG. 3 in order to determine the positions to be arranged in the arrangement units 13a to 13e of the input candidate display unit 12. The order is assigned from the first to the fifth. However, when the number of assigned one character or one symbol is 4 or less, the order is assigned as much as the order can be assigned.

  The 10 types of data are categorized by character / symbol type, and hiragana characters / symbol types include hiragana clear sounds, hiragana murmurs, hiragana prompts, stuttering, and hiragana half-sounds. There are four types of Katakana characters / symbol types: Katakana's clear sound, Katakana's muddy sound, Katakana's sound, and roar and Katakana's semi-voiced sound. There are two types of symbol types: numeric half-width characters, lowercase alphabetic characters, symbols and full-width numbers, alphabetic capital letters, and symbols.

  Each type of data assigned to each of the buttons 21 to 30 (see FIG. 1) of the input button unit 20 includes characters or characters displayed on the input candidate display unit 12 when the buttons 21 to 30 are continuously pressed. In order to switch symbols, as shown in FIG. 3, in the case of Hiragana characters / symbol types, Katakana characters in the order of Hiragana Kiyane, Hiragana muddy sound, Hiragana prompting sound, and Roar and Hiragana semi-voiced sound・ In the case of symbol type, in the order of Katakana Kiyomi, Katakana murmur, Katakana urgent sound, and roar and Katakana nuisance, alphanumeric characters / symbols. The symbols are assigned to the buttons 21 to 30 in the order of symbols, full-width numbers, alphabetic capital letters, and symbols.

  For example, as illustrated in FIG. 3, “A” is described in the button 21 (see FIG. 1) of the input button unit 20, and therefore hiragana is used by using the hiragana of hiragana out of 10 types of data. Of “A, I, U, E, O”, which is the clear sound of “A”, “A” is the first of the buttons 21, “I” is the second of the buttons 21, Is assigned to the third button 21, “e” is assigned to the fourth button 21, and “o” is assigned to the fifth button 21.

  In addition, as shown in FIG. 3, using the hiragana hiragana of 10 types of data, “a” of “a, i, ぅ, e, ぉ”, which is the roar of hiragana “a line”. The first of the buttons 21, “i” is the second of the buttons 21, “第三” is the third of the buttons 21, “é” is the fourth of the buttons 21, and “é” is the button 21 Assign to the fifth. Note that the hiragana and hiragana half-tones are not assigned to the button 21 because the hiragana and hiragana half-tones do not exist in the hiragana “a line”.

  Then, as shown in FIG. 3, the hiragana and hiragana assigned to the button 21 of the input button section 20 are divided into hiragana characters / symbol types, that is, hiragana kiyomi. And hiragana roar. Further, as shown in FIG. 3, each hiragana and each muffled sound of hiragana “A row” assigned to the button 21 of the input button unit 20 are displayed in the order of hiragana kanji and hiragana muffled sound, as shown in FIG. Assigned to.

  However, among the 10 types of data, in the case of using half-width numbers, lowercase letters, and symbols, as shown in FIG. 3, the button 21 (see FIG. 1) of the input button section 20 has a half-width number “1”. ”And the symbol“., @ ”, And the number of assigned one character or one symbol is 3, so that“ 1 ”of“ 1,. , “.” Is assigned to the second button 21, “@” is assigned to the third button 21, and nothing is assigned to the fourth and fifth buttons 21. The same applies to the case of using two-byte numeric characters, alphabetic capital letters and symbols among the ten types of data.

  Also, as shown in FIG. 3, among the 10 types of data, Katakana's clear sound, Katakana's muddy sound, Katakana's sound and roar, Katakana's semi-voiced sound, half-width numbers, lowercase letters and symbols, and full-width numbers -Uppercase letters and symbols of English letters are also assigned to the buttons 21 to 30 of the input button section 20 in the same manner as Hiragana.

  FIG. 4A shows the display of the input candidate display unit 12 when the button 21 is pressed once and when it is continuously pressed twice when the character / symbol type is set to hiragana. ing.

  When the button 21 is pressed once, “A”, which is the clear sound of the hiragana of “A line” assigned to the button 21 first, is assigned to the central arrangement portion 13e, and secondly assigned to the button 21. “I” is assigned to the upper arrangement part 13a, “U” assigned to the button 21 third is assigned to the right part 13b, and “E” assigned fourth to the button 21 is assigned to the lower arrangement part 13c. Fifthly, “o” assigned to the button 21 is displayed in the left part arrangement portion 13d.

  When the button 21 is pressed twice in succession, “a” which is the roar of the hiragana of “A row” assigned to the button 21 first is assigned to the central arrangement portion 13e, and secondly assigned to the button 21. “I” is assigned to the upper placement portion 13a, “ぅ” assigned to the button 21 third is assigned to the right placement portion 13b, and “e” assigned to the button 21 fourth is assigned to the lower placement portion 13c. In addition, the fifth symbol “ぉ” assigned to the button 21 is displayed on the left part arrangement portion 13d.

  FIG. 4C illustrates the display of the input candidate display unit 12 when the button 21 is pressed once and when it is continuously pressed twice when the character / symbol type is set to Katakana. FIG. 4 (e) shows an input candidate display section when the button 21 is pressed once and when it is continuously pressed twice when the character / symbol type is set to alphanumeric characters / symbols. Each of the twelve displays is illustrated.

  4 (b), FIG. 4 (d), and FIG. 4 (f), as in FIG. 4 (a), FIG. 4 (c), and FIG. Thus, the characters or symbols displayed on the input candidate display unit 12 are switched. If the character / symbol type is set to hiragana or katakana, the button 24 is assigned hiragana and katakana clear sounds, hiragana and katakana muffled sounds, hiragana and katakana prompting sounds. Therefore, FIGS. 4B and 4D show the display of the input candidate display unit 12 until it is continuously pressed three times.

  Thus, as shown in FIG. 4, when the character / symbol type is set to hiragana by continuously pressing any one of the buttons 21-30, the button is pressed. The hiragana assigned to the selected button switches in the order of clear sound, muddy sound, prompting sound and roaring sound, and semi-voiced sound. Similarly, if the character / symbol type is set to Katakana by continuously pressing any one of the buttons 21 to 30, the Katakana assigned to the pressed button is Each time the button is pressed, the sound changes in the order of clear sound, muddy sound, prompting sound and stuttering sound, and semi-turbid sound. Furthermore, when the same button of any one of the buttons 21 to 30 is continuously pressed and the character / symbol type is set to alphanumeric / symbol, it is assigned to the pressed button. Each time you press the button, the letters, numbers, and symbols are switched in the order of half-width numbers, lower-case letters, symbols, full-width numbers, upper-case letters, and symbols.

  Here, as shown in FIG. 4A, when the character / symbol type is set to hiragana, when the button 21 is pressed continuously three times, the button 21 newly displays the input candidate display section 12. Since the hiragana to be assigned is not assigned, the character / symbol type is set to katakana. The display on the input candidate display unit 12 is the same as when the button 21 is pressed once when the character / symbol type is set to hiragana as shown in FIG.

  If the character / symbol type is set to Katakana and the button 21 is pressed three times in succession, the button 21 is not assigned a new katakana character to be displayed on the input candidate display unit 12. Symbol type is set to alphanumeric / symbol. The display on the input candidate display unit 12 is the same as when the button 21 is pressed once when the character / symbol type is set to alphanumeric / symbol, as shown in FIG.

  That is, when the button 21 is continuously pressed and the character or symbol to be newly displayed on the input candidate display unit 12 is not assigned to the button 21, the character / symbol type is changed, and the changed character / symbol type is changed. Is used to display the character or symbol assigned to the button 21 on the input candidate display unit 12.

  Similarly, as shown in FIG. 4B, FIG. 4D, and FIG. 4F, when the button 24 is continuously pressed, a character or symbol that is newly displayed on the input candidate display unit 12 is a button. If the character / symbol type is not assigned, the character / symbol type is changed, and the character / symbol assigned to the button 24 is displayed on the input candidate display unit 12 using the changed character / symbol type.

  Therefore, the character / symbol type can be changed by pressing the buttons 33 to 30 in addition to pressing the button 33.

  FIG. 5 shows a list when characters or symbols assigned to the buttons 21 to 30 (see FIG. 1) of the input button unit 20 are displayed on the input candidate display unit 12. As shown in FIG. 5, the buttons 21 to 30 include a hiragana clear sound, a hiragana muffled sound, a hiragana sound and a roar, a hiragana half sound, a katakana clear sound, a katakana muffled sound, and a katakana sound. Roaring sound, katakana half-sound, number half-width / alphabetic lower-case letters / symbols, number full-width / alphabetic capital letters / symbols are assigned and displayed on the input candidate display section 12.

  However, in each of the buttons 21 to 30 (see FIG. 1), when the characters or symbols are not assigned to all of the first to fifth orders, the characters or symbols of the buttons 21 to 30 are assigned. Nothing is displayed on the arrangement parts 13a to 13d corresponding to the order in which they are not performed.

  For example, “1” is assigned to the first button 21, “.” Is assigned to the second button 21, “@” is assigned to the third button 21, and the fourth button 21 is assigned to the button 21. And nothing is assigned to the fifth, so as shown in FIG. 5, nothing is displayed on the lower arrangement portion 13 c and the left arrangement portion 13 d corresponding to the fourth and fifth of the button 21. Not.

  Returning to the description of FIG. The RAM 43 includes a character / symbol type counter 43a used for setting a character / symbol type for switching the characters or symbols displayed on the collective display unit 11 by pressing the buttons 21 to 30, and each button of the input button unit 20. There is provided a button data memory 43b for storing which button is pressed when any one of the buttons 21 to 35 and 36a to 36e (see FIG. 1) is pressed.

  Depending on the value of the character / symbol type counter 43a, the character / symbol type is set to hiragana, katakana, alphanumeric characters / symbols. The button data memory 43b is used for processing (see FIGS. 6 to 9) described later.

  Next, processing executed by the control unit 40 will be described with reference to FIGS. FIG. 6 is a flowchart showing interrupt processing performed periodically. FIG. 7 is a flowchart showing an input process for changing the process depending on the pressed button. FIG. 8 is a flowchart showing a character / symbol type process for switching the character / symbol type. FIG. 9 is a flowchart showing a display process for displaying a character or symbol assigned to a pressed button.

  When the display device 1 is set to an input screen for inputting characters or the like when creating an e-mail, for example, the character / symbol type data 43a in the state when the power stored in the EEPROM 44 is turned off is stored in the CPU 41. The CPU 41 sets the character / symbol type using the read character / symbol type data 43a and causes the character / symbol type display unit 16 to display the set character / symbol type.

  Next, the interrupt process shown in FIG. 6 is repeatedly executed by the CPU 41 (for example, at intervals of 0.2 ms) while the input screen is set. This interruption process determines whether each of the buttons 21 to 35 and 36a to 36d (see FIG. 1) of the input button unit 20 is newly pressed, and when it is determined that the button is newly pressed, This is a process for writing button data indicating whether or not the button is pressed into the button data memory 43b.

  In the interrupt process, as shown in FIG. 6, it is determined whether or not each of the buttons 21 to 35 and 36a to 36d (see FIG. 1) of the input button unit 20 is newly pressed (S1). As a result, if it is determined that a new button has been pressed (S1: Yes), it means that any of the buttons 21 to 35 and 36a to 36d has been pressed, and the process proceeds to S2. To do. In the process of S2, the button data of the newly pressed button is written into the button data memory 43b, and this interrupt process is terminated (S2).

  On the other hand, if it is determined in step S1 that a new button has not been pressed (S1: No), this means that no button has been pressed, and this interrupt processing is terminated (S1). .

  The input process shown in FIG. 7 is a process that is executed when button data is set in the input screen and is written into the button data memory 43b, and the input characters or symbols are input candidates using the written button data. This is a process for switching characters or symbols to be displayed on the input candidate display unit 12 in addition to being displayed on the display unit 12.

  In the input process, as shown in FIG. 7, it is determined whether there is new button data in the button data memory 43b (S11). As a result, if it is determined that there is new button data (S11: Yes), it means that any one of the buttons 21 to 35 and 36a to 36d has been pressed. Transition. On the other hand, if it is determined in step S11 that there is no new button data (S11: No), this means that no button has been pressed, and this input process is terminated (S11).

  In the processing of S12, it is determined whether or not the new button data is the character button 33, that is, whether or not the character / symbol type is switched (S12). As a result, when it is determined that the new button data is the character button 33 (S12: Yes), the process proceeds to S13, and the character / symbol type process (S13) for switching the character / symbol type is executed. The

  The character / symbol type process is a process for switching the character / symbol type, and the character / symbol type is set using a character / symbol type counter 43a as shown in FIG. Here, when the value of the character / symbol type counter 43a is 0, the character / symbol type is set to Hiragana, and when the value of the character / symbol type counter 43a is 1, the character / symbol type is set to Katakana. When the value of the symbol type counter 43a is 2, the character / symbol type is set to alphanumeric characters / symbols.

  In the character / symbol type process, as shown in FIG. 8, the value of the character / symbol type counter 43a is incremented by 1, and the process proceeds to S22 and subsequent steps (S21).

  In the process of S22, it is determined whether or not the value of the character / symbol type counter 43a is 3 or more (S22). As a result, when it is determined that the value of the character / symbol type counter 43a is 3 or more (S22: Yes), the process proceeds to S23, and the value of the character / symbol type counter 43a is set to 0 (S23). . Thereafter, the process proceeds to S24.

  On the other hand, in the process of S22, when the value of the character / symbol type counter 43a is not 3 or more, that is, the value of the character / symbol type counter 43a is 2 or less (S23: No), the process proceeds to S24.

  In the process of S24, the character / symbol type corresponding to the value of the character / symbol type counter 43a is set (S24), and the character / symbol type process is terminated. With this character / symbol type process, the setting of the character / symbol type for switching the character or symbol displayed on the input candidate display unit 12 by pressing each of the buttons 21 to 30 (see FIG. 1) is completed.

  Returning to the description of S12. In the process of S12, when it is determined that the new button data is not the character button 33 (S12: No), there is a possibility of input of a character or a symbol, so the process proceeds to S14 and subsequent steps.

  In the process of S14, it is determined whether or not the new button data is any of the buttons 21 to 30 (see FIG. 1) (S14). As a result, when it is determined that the new button data is any of the buttons 21 to 30 (S14: Yes), the process proceeds to S15, and the display process for displaying the characters and symbols on the collective display unit 11 is performed. (S15) is executed.

  The display process is a process for causing the collective display unit 11 to display characters or symbols assigned to the buttons 21 to 30 (see FIG. 1) of the input button unit 20, as shown in FIG. In addition to displaying the input character or symbol on the input candidate display unit 12 using the button data written in 43b, one character or one symbol is selected from the characters or symbols displayed on the input candidate display unit 12. This is a process for displaying the input confirmation on the input confirmation display section 14.

  In the display process, as shown in FIG. 9, the value of n is set to 1, and the process proceeds to S32 and subsequent steps (S31). In the process of S32, using the new button data in the button data memory 43b, the first assigned character of the n-th press of the button corresponding to the new button data is assigned to the central arrangement unit 13e of the input candidate unit 12. The second assigned character or symbol is assigned to the upper placement portion 13a of the input candidate portion 12, and the third assigned character or symbol is assigned to the right placement portion 13b of the input candidate portion 12. The character or symbol assigned to is displayed on the lower placement portion 13c of the input candidate portion 12, and the fifth assigned character or symbol is displayed on the left placement portion 13d of the input candidate portion 12, respectively. (S32).

  By the process of S32, the characters or symbols assigned to the buttons from the second to the fifth are arranged clockwise. The arrangement of the characters or symbols assigned to the buttons from the second to the fifth may be counterclockwise.

  In the process of S33, it is determined whether or not the button data in the button data memory 43b has been updated, that is, whether or not a new button has been pressed (S33). As a result, if it is determined that a new button has been pressed (S33: Yes), it means that any of the buttons 21 to 35 and 36a to 36d (see FIG. 1) has been pressed. The process proceeds to S34 and subsequent steps. On the other hand, if no new button is pressed in the process of S33 (S33: No), it means that no button is pressed, so the process proceeds to S32 and the display of S32 is continued.

  In the process of S34, new button data is read from the button data memory 43b (S34). The read new button data is used for the processing after S35.

  In the process of S35, it is determined whether or not the new button data is any of the buttons 21 to 30, that is, whether or not a character or symbol is input (S35). As a result, if it is determined that the new button data is one of the buttons 21 to 30 (S35: Yes), it means that a character or symbol has been input, and the process proceeds to S36 and subsequent steps. To do.

  In the process of S36, it is determined using the button data in the button data memory 43b whether the new button data is the same as the previous button data, that is, the previous button data (S36). That is, here, it is determined whether or not the same button has been pressed twice in succession (S36).

  As a result, when it is determined that the new button data is not the same as the previous button data (S36: No), it is different from the character or symbol displayed on the input candidate display unit 12 by the button pressed last time. Therefore, the processing returns to the process of S32, and instead of the character or symbol assigned to the button corresponding to the previous button data, the character assigned to the button corresponding to the new button data or The symbol is displayed on the input candidate display unit 12 (S32).

  On the other hand, in the process of S36, when it is determined that the new button data is the same as the previous button data (S36: Yes), the character or symbol displayed in the input candidate unit 12 is displayed in another display (for example, Since it is desired to switch from hiragana clear sound to hiragana muffled sound, the process proceeds to S37 and subsequent steps for executing this switching process.

  In the process of S37, the value of n is incremented by 1, and the process proceeds to S38 (S37). In the process of S38, it is determined whether or not there is a character to be newly displayed in the center arrangement portion 13e among the first characters of the (n + 1) pressed button assigned to the button corresponding to the new button data. In the character / symbol type setting, it is determined whether there is an n + 1 first-pressed character assigned to the button corresponding to the new button data (S38).

  As a result, when it is determined that there is a first character of the (n + 1) pressed button assigned to the button corresponding to the new button data in the current character / symbol type setting (S38: Yes), the process proceeds to S32. Returning to the processing, instead of the characters or symbols displayed in the input candidate section 12, switching to another display (for example, hiragana clear sound to hiragana muffled sound), the characters assigned to the button corresponding to the new button data Alternatively, the symbol is displayed on the input candidate display unit 12 (S32).

  For example, as shown in FIG. 4B, when the current character / symbol type is set to hiragana, if the button 24 is pressed twice in succession, the second press assigned to the button 24 It is determined that there is the first character (S38: Yes), the process returns to the process of S32, and FIG. 4 (b) displayed in the input candidate section 12 is replaced with a single press in FIG. 4 (b). The double press is displayed on the input candidate display unit 12 (S32).

  On the other hand, if it is determined in the processing of S38 that there is no first character at the (n + 1) th press assigned to the button corresponding to the new button data in the current character / symbol type setting (S38: No). ) In order to change the current character / symbol type setting, the process proceeds to S39, and the character / symbol type process is executed (S39). In the character / symbol type process, when the setting of the character / symbol type is changed (S39), the process returns to the process of S31, moves to the process of S32 after the process of S31, and is displayed on the input candidate unit 12 Instead, the character or symbol assigned to the button corresponding to the new button data is displayed on the input candidate display unit 12 using the changed character / symbol type (S32).

  For example, as shown in FIG. 4B, when the current character / symbol type is set to hiragana, if the button 24 is pressed four times in succession, 4 assigned to the button 24 in the process of S38. It is determined that there is no first character of the second press (S38: No), and the process proceeds to the character / symbol type process of S39. When the setting of the character / symbol type is changed to Katakana by the process of S39, the process returns to the process of S31, and after the process of S31, the process proceeds to the process of S32. A single press in FIG. 4D is displayed on the display unit 12 (S32).

  Returning to the description of S35. In the process of S35, when it is determined that the new button data is not one of the buttons 21 to 30 (S35: No), the character or symbol displayed on the input candidate display unit 12 is selected and the input is confirmed. Since it is considered that the buttons 36a to 36e for pressing are pressed, the process proceeds to S40 and subsequent steps.

  In the process of S40, it is determined whether or not the new button data is a button 36a to 36e (see FIG. 1), that is, whether or not the input is confirmed (S40). As a result, if it is determined that the new button data is not one of the buttons 36a to 36e (S23: No), it means that the input is not confirmed, so the process proceeds to S32 and the display of S32 is performed. To continue.

  On the other hand, in the process of S40, when it is determined that the new button data is any of the buttons 36a to 36e (S40: Yes), the character or symbol displayed on the input candidate display unit 12 is selected. At the same time, since the buttons 36a to 36e have been pressed to confirm the input, the process proceeds to the process of S41 which is the input confirmation process (S40).

  In the process of S41, if the new button data is the button 36a, the character or symbol displayed on the upper placement portion 13a is displayed. If the new button data is the button 36b, the character displayed on the right placement portion 13b. Or, if the new button data is the button 36c, the character or the symbol displayed on the lower placement portion 13c, or if the new button data is the button 36d, the character or the symbol displayed on the left placement portion 13d If the new button data is the button 36e, the symbol is selected from the character displayed in the center placement portion 13e, the selected character or symbol is displayed at the position of the left placement portion 13d, and the input is confirmed and confirmed. The characters or symbols that are not displayed are deleted, the input cursor is advanced by one, and the display process is terminated (S41). When the input of the character or symbol is confirmed, the confirmed character or symbol is displayed on the input confirmation display unit 14 so that conversion (for example, kanji) is possible.

  As described above, when characters or symbols are input to the display device 1 and displayed on the collective display unit 11, any one of the buttons 21 to 30 to which the characters or symbols to be input are assigned is pressed and assigned to the button. After the displayed character or symbol is displayed on the input candidate display unit 12, the character or symbol to be input may be selected using the buttons 36a to 36e. It is possible to search for a character or symbol to be input easily and quickly without the need to press the button repeatedly.

  Next, with reference to FIG. 10, a procedure for inputting and displaying characters on the collective display unit 11 using the display device 1 will be described. FIG. 10 is an explanatory diagram for inputting hiragana to the collective display unit 11. A case will be described in which the character “Today” has already been input and determined in the collective display unit 11 and is displayed on the input determination display unit 15 and “kick” is input after the character.

  First, it is confirmed on the display of the character / symbol type display unit 16 whether the setting of the character / symbol type is hiragana. In the case of FIG. 10, since the display of the character / symbol type display unit 16 is hiragana input, the character / symbol type is set to hiragana. Next, the button 22 (see FIG. 1) is pressed once in order to input the hiragana voice “ka”. As a result, as shown in FIG. 10A, the input candidate display unit 12 displays “Ka, Ki, Ku, Ke, Ko”, which is a clear sound of the Hiragana “Ka” line. Then, the hiragana voice “K” is selected and the button 36e (see FIG. 1) is pressed to confirm the input. As a result, as shown in FIG. 10B, the input of the hiragana clear sound “ke” is confirmed.

  Next, the button 24 (see FIG. 1) is pressed three times in succession in order to input the hiragana prompt “tsu”. As a result, as shown in FIG. 10C, the input candidate display unit 12 displays “tsu” which is the prompt sound of the hiragana “ta” line. Then, the hiragana prompt “tsu” is selected, and the button 36e (see FIG. 1) is pressed to confirm the input. As a result, as shown in FIG. 10 (d), the input of the hiragana prompt “tsu” is confirmed.

  Then, the button 24 (see FIG. 1) is pressed once in order to input the hiragana voice “ta”. As a result, as shown in FIG. 10 (e), the input candidate display unit 12 displays “Tachi, Tsu, Teto”, which is the clear sound of the hiragana “ta” line. Then, the hiragana clear sound “ta” is selected and the button 36e (see FIG. 1) is pressed to confirm the input. As a result, as shown in FIG. 10F, the input of the hiragana clear sound “ta” is confirmed.

  Next, the button 34 having a conversion function is pressed in order to convert the character “Ked” displayed on the input confirmation display unit 14 into the kanji “kick” after the input is confirmed. As a result, as shown in FIG. 10G, “kick”, which is a conversion candidate for “kita”, is displayed on the input confirmation display unit 14. Finally, in order to input and determine the conversion candidate “kicked”, the button 36 is pressed, and “kicked” is determined to be input and displayed on the input determination display unit 15 as shown in FIG. .

  As described above, the present invention has been described based on each embodiment, but the present invention is not limited to the above-described embodiment, and various modifications can be easily made without departing from the gist of the present invention. Can be inferred.

  In the present embodiment, for example, as shown in FIG. 6 (d), the prompt sound “tsu” is displayed only on the central arrangement portion 13e, but when there is only one pseudonym assigned to the button, You may display on all the arrangement | positioning parts 13a-13e. In this case, when confirming the input, any of the buttons 36a to 36e may be pressed, and the input of characters or symbols can be confirmed more easily and quickly.
