In the fifth embodiment, as described in the first embodiment, the kana character expression data d1
In the case of the rotary dial buttons shown in the block diagram of FIG. 8 when stored in the kana character expression data storage device 105, a kana character input method using an input device using the button having the function (3) described above is described. According to a display example of the display shown in FIG. 14, an operation of inputting "Yoshida" similar to that described in the related art will be described.

(Description of Operation) First, the operation of the dial rotary button 115 will be described. The dial rotary button 115 can be operated in the left-right rotation direction with respect to the axis of the button, and the content to be read changes depending on the number of rotations.
Here, it is assumed that the line of the kana character expression data can be switched. The cursor is displayed at the beginning of each line while switching lines. On the other hand, the cursor moves sideways each time the button is pressed once. Hereinafter, the input of "Yoshida" will be described as an example.

If the function button 113 is pressed in the registration waiting state, the CPU 108 displays a display [701] on the display 107 in a character registration mode. Here, if the button 113 is pressed again, the CPU 108 reads the “A” line from the data storage device 105 and reads

Next, the user presses the dial 115 twice, moves the cursor sideways to match the character "S" [707], and presses the function button 113. When the function button 113 is pressed, the CPU 108 determines that the character has been determined. Is displayed in the lower row [708].

Subsequently, when the dial 115 is rotated one time to the right with respect to the axis to select the “ta” line, the CPU 108 displays the “ta” line read from the storage device 105 on the display 107 [709]. Here, since the cursor is already under “ta”, when the function button 113 is pressed, the CPU 108 determines that “ta” has been determined and displays it in the lower part of the display 107 [710]. Further, the user presses the dial 115 five times to move the cursor sideways to match “゛” [711]. When the function button 113 is pressed, the CPU 108 determines that “゛” has been determined.
It is displayed on the lower part of the display 107 [712]. If the function button 113 is further pressed, the CPU 108 determines that the character displayed in the lower part of the display 107 has been determined, stores the determined character string in the memory 106, and displays on the display 107 that registration has been completed [ 713].

In the above description, the line is switched each time the dial is rotated left and right with respect to the axis, and the cursor is moved horizontally each time the dial is pressed. However, the present invention is not limited to this. For example, a method may be used in which the display of rows is switched every second while the dial is rotated to the right by a predetermined angle with respect to the axis, and the release of the dial is confirmed. Similarly, it is also possible to adopt a method in which the cursor moves side by side every one second while the dial button is pressed, and the release is confirmed when the dial button is released.

Next, using the flowchart shown in FIG.
An operation flow of the kana character input method according to the fifth embodiment of the present invention will be described.

(Operation Flow) If the function button 113 is pressed in the registration waiting state (step S81), the CP
U108 displays a display indicating that the character registration mode has been entered on display 107 (step S82). Here again 1
13 is pressed (step S83), the CPU 108
Reads the row "A" from the data storage device 105 and displays it on the display 107 (step S84). Next, when the dial rotary button 115 is rotated three times to the left (step S85), the CPU 108 reads a line from the storage device 105 (step S86), and displays the “Y” line on the display 107 (step S87). . Next, if the dial 115 is pressed twice (step S88), the cursor is moved to “Y” (step S89), and if the function button 113 is pressed (step S90), the CPU 10 is pressed.
8 is determined to be a character in which “Y” has been determined (step S91), and is displayed in the lower part of the display 107.

Next, when the dial rotary button 115 is rotated rightward five times (step S85), the CPU 10
8 reads a row from the storage device 105 (step S8).
6) The “sa” line is displayed on the display 107 (step S87). Next, if the dial 115 is pressed twice (step S88), the cursor is moved sideways (step S89) to match "S", and if the function button 113 is pressed (step S90), the CUP 108 is set to "S". Is determined as the determined character (step S91), and is displayed at the bottom of the display 107.

Here, since the cursor is located below “sa”, if the dial 115 is continuously pressed (step S
88) It is also possible to select a character by moving the cursor sideways (step S89). If the cancel button 104 is pressed after one character is determined (step S89), the CPU 108 deletes one character from the display 107 (step S9).
3). On the other hand, after confirming one character, the function button 113
Is pressed (step S94), the CPU 108 determines that all the characters displayed in the lower part of the display 107 have been determined (step S95), stores the determined character string in the memory 106, and notifies that the registration has been completed. The information is displayed on the display 107 (step S96), and the process ends (step S97). Next, regarding a sixth embodiment of the present invention,
This will be described with reference to the block diagram shown in FIG. 9 and the flowchart of FIG.

An operation flow for inputting “Yoshida” similar to that described in the related art will be described.

(Explanation of Operation) If a speech "talk" is input from the microphone 116 in the state of waiting for registration (step S101), the speech recognition unit 117 recognizes that the command is for shifting to the registration mode. The display that has entered the character registration mode is displayed on the display 107 (step S102). Here, if “Kaishi” is uttered and input from the microphone 116 (step S103), the voice recognition unit 117 recognizes it as a command to start name registration, and the CPU 108
, And reads out the "A" line from the display 107 (step S104). Next, when "ue" is uttered and input three times (step S105), the speech recognition unit 117 recognizes the command as a command for switching the line upward, and
08 reads a row from the storage device 105 (step S1).
06), the “ya” line is displayed on the display 107 (step S107). Next, when “horizontal” is uttered twice and input from the microphone 116 (step S108),
The voice recognition unit 117 recognizes the command as a command for switching in the horizontal direction, moves the cursor horizontally to “Y” (Step S109), and utters and inputs “Kakutei” from the microphone 116 (Step S110). ),
The voice recognition unit 117 recognizes the character on the cursor as a command for determining the character, and the CPU 108 determines that “Y” is the determined character (step S111) and displays the character on the lower part of the display 107.

Next, when "sita" is uttered and input five times from the microphone 116 (step S105), the voice recognition unit 117 recognizes it as a command for switching downward, and the CPU 108 reads a row from the storage device 105. (Step S106), the “Sa” line is displayed on the display 107.
(Step S107). Next, when “horizontal” is uttered once and input from the microphone 116, the voice recognizing unit 117 recognizes the command as a command for switching in the horizontal direction, and moves the cursor horizontally to match “shi” (step). In step S109), when the microphone 116 utters and inputs “kakutei” (step S110), the voice recognition unit 102 recognizes the command as a command for determining the character on the cursor, and the CPU 108 determines the character in which “shi” has been determined. (Step S111), the display 107
Is displayed at the bottom.

At this time, if "microphone" is uttered and input to the microphone 116 (step S112), the voice recognition unit 117 recognizes the command as one character erasure command of the determined character, and the CPU 108 displays the lower row of the display 107. Is deleted (step S113). On the other hand, after one character has been determined, when “name” is further uttered and input from the microphone 116 (step S114), the voice recognition unit 117 issues a command for registering the character string displayed at the lower part of the display 107 as a name. Upon recognition, the CPU 108 determines that the character displayed in the lower part of the display 107 has been determined (step S115), stores the determined character string in the memory 106, and displays on the display 107 that registration has been completed (step S116). ) End (Step S11)
