FIG. 3 is a character list 40 showing all the characters that can be input. The characters shown in the character list 40 are stored in the character storage unit 10. In addition, one section (hereinafter referred to as a “page”) divided by a thick line frame in the figure is displayed on the character panel 21 at a time. In this terminal device, when an application that is a specific use is started, a page including a character frequently used in the application is displayed first as an initial screen.
The application and the page displayed on the initial screen correspond to each other, and the information relating to this correspondence is held by the display control unit 11, which also has a function of a page information holding unit. This character list 40 is commonly used in the following embodiments.

Next, the operation of this embodiment will be described with reference to the flowchart of FIG. In FIG. 4, the terminal device 1
Is activated, a menu screen for the user to select an application is displayed on the character panel 21 (S30). When the user selects one of the applications, a page corresponding to the application is displayed as an initial screen on the character panel 21 based on the information of the display control unit 11 (S31). Here, as an example,
It is assumed that the initial screen displays a page 40a at the upper left end of the character list 40 as shown in the character panel 21 of FIG. Next, when the user operates the cursor movement key 31 or the selection key 32 to perform key input (S32),
The key input determination unit 4 determines whether or not the operated key is the cursor movement key 31 (S33). If the operated key is not the cursor movement key 31, that is, if the operated key is the selection key 32, The character / icon determining unit 6 determines whether the position of the cursor 21c at this time is the character 21a or the icon 21b.
(S34-S35).

The position of the cursor 21c is the icon 21
If it is not b, that is, if it is the character 21a, the character input processing unit 9 performs a character input process of inputting the code of the character from the code table storage unit 8 to the display control unit 11 (S3).

In S33, if the key operated by the user is the cursor movement key 31, the character panel 21 needs to be switched according to the position of the cursor 21c and the direction of the selected cursor movement key 31 at that time. The display control unit 11 determines whether or not it is (S38). Whether the character panel 21 needs to be switched is determined by determining whether the cursor 21c is located at one of the upper, lower, left, and right ends of the character panel 21 and the selected cursor movement key 31
Is determined to be a direction in which the cursor 21c protrudes from the character panel 21, it is determined that switching of the character panel 21 is necessary, otherwise, it is determined that switching is not necessary. If it is determined that it is not necessary to switch the character panel 21, the cursor 21c is moved in the direction indicated by the cursor movement key 31 without changing the display on the character panel 21 (S39), and the cursor 21c is displayed at a new position. (S41).

If it is determined that the character panel 21 needs to be switched, the display is switched to the next page determined by the page displayed on the character panel 21 and the direction of the selected cursor movement key 31. A page switching process is performed (S40), and a new page is displayed (S40).
41). For example, when the cursor 21c is repeatedly pressed by the downward cursor movement key 31a while the cursor 21c is at the position of "a" in the character panel 21 displaying the page 40a, the cursor 21c is sequentially turned to "ka", "sa", "ta". ""
“Ha” moves to reach the end of the character panel 21. Here, if the cursor movement key 31a is pressed further downward,
Since the cursor 21c is in the direction protruding from the character panel 21, the page switching process is performed, and the display is switched to the page 40b located below the page 40a in the character list table 40. Move to the position.

As described above, when the cursor moving key 31a is further pressed while the cursor 21c is at the bottom of the page 40a, the display is switched to the page 40b.
The cursor 21c moves to a position one stage below the previous position in the character list table 40, and is displayed at the top in a new display.

When the cursor 21c is located at the rightmost column (a column including the icons of the up arrow, the down arrow, the left arrow, and the right arrow) of the page 40a and the cursor right key 31c is pressed, a character list is displayed. Page 40 within 40
The display is changed to a page 40c on the right side of a, and the cursor 21c is moved one position from the previous position in the character list 40.
It moves to the right position of the column and is displayed in the leftmost column in the new display. As described above, when the cursor 21c is at the end of the character panel 21 and a page exists in the character list 40 in the direction selected by the cursor movement key 31, the display changes to the adjacent page.

When the cursor 21c is at the end of the character panel 21 and there is no page in the character list 40 in the direction selected by the user with the cursor movement key 31, for example, the page 40a is displayed. The leftmost column ("A", "KA", "SA", "TA", "NA", "HA" columns)
The cursor 21c, and the left cursor movement key 3
When 1b is selected, the displayed page changes to 40c, and the cursor 21c is displayed in the rightmost column in the new display. Similarly, for example, when the page 40a is displayed and the cursor 21c is at the top of the page ("a", "i" to "ko"), the upward cursor movement key 3
If the user selects 1d, the displayed page is 4
The cursor 21c is changed to 0d, and the cursor 21c is displayed at the bottom in the new display.

FIG. 1 is a diagram showing an example in which the word "Kanagawa" is input from the page 40a.
This is an example in which characters up to “na” and “ga” are selected and displayed in the first input area 22, and the cursor 21c is located at the position of “ga”. Next, in order to input the character of "wa", the character panel 21 needs to be switched. However, since the page 40b including the character of "wa" is below the page 40a, the user needs to use the downward cursor movement key. By repeatedly pressing the button 31a, the cursor 21c is moved downward, and the cursor 21c is moved to a small "a" position at the bottom. When the downward cursor movement key 31a is further pressed, the display of the character panel 21 is switched to the page 40b, and the display shown in FIG. Immediately after switching, the cursor 21c is displayed as a small "ya" at the top.
, The user can move the cursor down key 3
The cursor 21c is moved to the position of "W" by the cursor movement key 31b for the left and the right.
By pressing, “Wa” is displayed in the first input area 22.

As described above, in the terminal device using the character input device according to the present embodiment, the user operates the cursor movement key 31 to move the cursor 21c, thereby changing the display on the character panel 21 to a page. Since switching can be performed in units, even if the terminal device has a small display screen on which all of the character list cannot be displayed at one time, the user can quickly select and input characters.

In the above description, only the character input function of the terminal device 1 has been described. However, the terminal device 1 may be provided with, for example, a telephone function in addition to the above-described character input function. A communication means, a microphone, a speaker, or other operation keys may be provided. In the above example, the cursor 21c is displayed under the character 21a or the icon 21b. The display of the character 21a or the icon 21b may be thin or the display may blink.

In the above example, for example, the page 40a
Is displayed, and when the cursor left key (31b) is further selected while the cursor 21c is in the leftmost column (columns "A" to "HA"), the displayed page changes to 40c. An example was shown, but cursor 2
If 1c is located at the end of the character panel 21 and there is no page in the character list 40 in the direction protruding from the character panel 21 selected by the user with the cursor movement key 31, the page may not be changed. In this case, there is an effect that the processing when the cursor 21c is at the end of the character panel 21 is simplified.

In the above example, for example, the page 40a
Is displayed, and when the cursor moving key 31a is further pressed in a state where the cursor 21c is located at the position of the small "a" at the bottom, the display of the character panel 21 is changed to the page 40b.
, And immediately after the switching, the cursor 21c is positioned over the small "ya" at the top row.
In the example shown above, the cursor 21c immediately after switching to the page 40b is located at the position "6" in this example.
1c may be located at the same position on the character panel 21. The cursor 21c before and after the page is switched
Is a continuous position on the character list 40,

Embodiment 4 Embodiment 4 will be described with reference to FIGS. 11 to 16. In the first to third embodiments described above, an example in which characters in the character list are input to the first input area 22 has been described. However, in the present embodiment, a kanji character not in the character list is input. This is an example having a Kana-Kanji conversion function for performing the conversion.

FIG. 11 is a diagram of a terminal device using the character input device according to the present embodiment.
FIG. 13 is a block diagram of the present embodiment, FIG. 13 is a flowchart of kana-kanji conversion processing in the present embodiment, FIGS. 14 and 15 are diagrams showing a state of kana-kanji conversion in a terminal device in the present embodiment, and FIG. FIG. 9 is a diagram illustrating a terminal device when conversion is not performed.

In FIG. 11, the key input unit 3 is provided with a conversion key 33 in addition to the cursor movement key 31 and the selection key 32. Further, an OK icon 50 indicating "ok" is provided in a part of the icon 21b. The components other than the conversion key 33 and the OK icon 50 are the same as those of the terminal device 1 shown in FIG.

In the block diagram of FIG. 12, reference numeral 51 denotes a kana-kanji conversion processing unit which is a character processing means. It is determined whether or not to convert the character into a kanji, and the character storage unit 10 is notified.
Except for the kana-kanji conversion processing unit 51, it is the same as the block diagram shown in FIG.

Next, the operation will be described with reference to the flowchart of FIG. In the character input according to the present embodiment, (a) a character input operation, (b) a conversion operation, and (c)
Characters are input through three stages of operations of a determination operation.

First, in the character input operation (a), the user moves the cursor to a desired character position on the character panel 21 using the cursor movement key 31 (S60). At this time, if it is necessary to switch the character panel, as described in the first embodiment, the cursor 21c is moved in a direction protruding from the character panel 21 by the cursor movement key 31, and the character panel is switched. Subsequently, by pressing the selection key 32, a character is input in the first input area 22 (S61). When a character is input to the first input area 22, the cursor 21c is moved to the position of the leftward or rightward icon among the icons 21b, and the selection key 32 is pressed. Since the character is moved by a distance, a character can be inserted at a new position. As described above, the character string is input to the first input area 22. Naturally, this string does not include kanji.

(B) The conversion operation is performed by pressing the conversion key 33 after the user inputs a character string in the first input area 22 by the above-mentioned (a) character input operation (S62).
Execute the Kana-Kanji conversion process of the character in the input area 22 (S

A part of 1 is displayed as the conversion candidate frame 52, and a list of conversion candidates is displayed (S64). A fourth cursor 52a is displayed below any one of the conversion candidates.
The cursor 52a can be moved by the up and down keys of the cursor movement key 31.

(C) For the confirmation operation, a cursor is selected from the conversion candidates by moving the fourth cursor 52a in the conversion candidate frame 52 with the cursor movement key 31 (S6).
5) Further, the selection key 32 is pressed down (S66). Thus, the character string in the first input area 22 is determined as shown in FIG. 15A, and the display of the conversion candidate frame 52 disappears (S67).

Further, by pressing the selection key (S68),
As shown in FIG. 15B, a character string is registered in the second input area 23 (S69).

FIG. 16 is an explanatory diagram of the OK icon 50 on the character panel 21. The OK icon 50 is an icon prepared for use when a character string selected on the character panel 21 and input to the first input area 22 is directly registered in the second input area 23 without being converted. For example, when the cursor 21c is positioned on the OK icon 50 and the selection key 32 is pressed in a state where “Akino” is input in the first input area as shown in FIG.
As shown in (b), "Akino" can be input to the second input area 23 without converting this character string.

As described above, in the character input device according to the present embodiment, after the character string in the first input area 22 is converted by the conversion key, the desired character is selected from the candidates by pressing the selection key. Further, since the converted character string is input to the second input area 23 by further pressing the selection key, there is an effect that it is possible to input Japanese characters including kanji not included in the character list.

In the above description, the OK icon 50
Has been described with an icon, but the function may be realized as a hardware key (OK key) of the key input unit 3. When the OK key is provided, regardless of whether the character string in the first input area 22 is before or after the conversion, only pressing the OK key causes the second input area 23 to be pressed.
And the operation can be simplified.
