  The communication module 102 converts a signal for a call from the CPU 100, an information signal such as an e-mail, and the like into a radio signal and transmits the signal from the antenna 102a to the base station. Further, the communication module 102 converts the radio signal received by the antenna 102a into a signal for a call, an information signal such as an e-mail, and the like, and outputs the signal to the CPU 100. Thereby, a signal for a call, an information signal such as an electronic mail, and the like are transmitted / received from the communication target device via the base station.

  The memory 101 is a storage unit including a ROM and a RAM. The memory 101 stores a control program for giving a control function to the CPU 100, various applications, a plurality of key assignment tables used when the applications are executed, and the like.

  Here, the “key assignment table” refers to key input made by the user and various characters displayed on the display surface 21b and functions to be operated (determination, cancellation, movement of the cursor and focus, etc.) according to the key input. (Refer to FIG. 3).

  The CPU 100 operates the communication module 102, the liquid crystal panel 21a, the panel backlight 21c, the speaker 22, and the like according to a control program based on signals from the microphone 12 and the key input circuit 103. As a result, various applications such as a call function and an e-mail function are executed.

  The CPU 100 outputs a control signal to the video decoder 106 and the light source driving circuit 105 as a display control circuit. Thereby, the liquid crystal panel 21a and the panel backlight 21c operate, and an image is displayed on the display surface 21b.

  Further, when an input signal indicating that any key has been pressed is input from the key input circuit 103, the CPU 100 refers to the key assignment table stored in the memory 101. Here, the CPU 100 normally switches the key assignment table to be referred to according to the currently active program and the current input mode of the program. Then, the CPU 100 executes processing corresponding to the character or function assigned to the pressed key in the key assignment table to be referred to.

  The memory 101 is referred to in each input mode (hereinafter referred to as “number input mode”, “kana input mode”, and “kana input mode”, respectively) for the user to mainly input numerals, hiragana and katakana characters. A key assignment table to be stored is stored.

  Actually, the key assignment table referred to in the numeric input mode and the kana input mode includes a mode for inputting full-width characters (2-byte characters) and a mode for inputting half-width characters (1-byte characters). And is stored in the memory 101. In the present embodiment, for the sake of convenience, it is assumed that each input mode is a mode for inputting full-width characters at all times. In addition to the input mode, the memory 101 stores a plurality of key assignment tables that are referred to in various input modes for mainly inputting various characters such as lowercase letters, uppercase letters, and symbols. The memory 101 may store an individual key assignment table required by each application in addition to the above-described key assignment table for general character input.

  FIG. 3 is a diagram for explaining an example of a key assignment table stored in the memory 101. FIGS. 3A, 3B, and 3C show key assignment tables that are referred to in the numeric input mode, the kana input mode, and the kana input mode, respectively.

  In the key assignment table in the numeric input mode shown in FIG. 3A, the dial characters as printed on the upper surface of each key are input to each key of the dial key group 50 as shown in FIG. Each corresponds. For example, when the user presses the “5” key, the CPU 100 displays the character “5” on the display surface 21 b.

  In the key assignment table in the Kana input mode shown in FIG. 3B, “number of times of pressing” means the number of times the key is continuously pressed at an interval shorter than a predetermined time interval. The user can input hiragana as shown in FIG. 3B by pressing one of the dial key group 50 once or continuously several times. For example, when the “1” key is continuously pressed 1 to 5 times, the CPU 100 displays the characters “A” to “O” in the “A” level corresponding to the number of presses on the display surface 21 b. Further, as shown in FIG. 3B, a line feed that is a control character for revising a line of a sentence is assigned to the “#” key.

  In the key assignment table in the kana input mode shown in FIG. 3C, the user presses one of the dial key groups 50 once or continuously several times at an interval shorter than a predetermined time interval, thereby Katakana can be input as shown in 3 (c). For example, when the “1” key is continuously pressed 1 to 5 times, the CPU 100 displays the characters “A” to “O” in the “A” level corresponding to the number of presses on the display surface 21 b. Similarly to FIG. 3A, the “#” key is assigned a line feed, which is a control character for revising a sentence line.

  Note that the CPU 100 may process to accept a key input for character input so that the user can change a predetermined input mode. Thus, the user can input a character string made up of a plurality of types of characters. Further, the CPU 100 may accept key input for character input so that the input mode cannot be changed. For example, when CPU 100 accepts input of a telephone number for a call, the input mode is normally fixed to a numeric input mode.

  In the present embodiment, when any key is input when the mobile phone 1 is in the standby state, an input screen (referred to as a “character dial screen” in the following description) is displayed on the display surface 21b. Is displayed, and characters corresponding to the key input are displayed on the character dial screen. The user can activate an application corresponding to the operation by continuously performing a predetermined operation on the character dial screen. At this time, the characters displayed on the character dial screen are incorporated in the application operation screen (a dial input screen and an e-mail text editing screen described later) displayed on the display surface 21b. Hereinafter, this function will be described in detail.

  FIG. 4 is a flowchart showing the procedure of the character / dial input program execution process. FIG. 5A is a diagram illustrating a standby screen displayed on the display surface 21b when the mobile phone 1 is in a standby state. FIG. 5B is a diagram illustrating a character dial screen displayed on the display surface 21b when the character / dial input program is activated.

  In a state where the standby screen shown in FIG. 5A is displayed, the CPU 100 accepts input from the user. When a user presses any key in the dial key group 50, the CPU 100 executes a character / dial input program.

  When one of the keys is pressed by the user, a character dial screen showing two characters corresponding to the key input as shown in FIG. 5B is displayed on the display surface 21b. For example, when the “0” key is pressed, the character “0” (hereinafter, the character string displayed in the region R1 is referred to as the “first character string” in the region R1 at the bottom of the screen on the character dial screen. .) Is displayed. A first cursor C1 is displayed at the end of the first character string. The cursor indicates an additional position where a character following the previously input character is added. The first character string is composed of dial characters (corresponding to the first character type of the present invention). In addition, the character “WA” (hereinafter, the character string displayed in the region R2 is referred to as “second character string”) is displayed in the region R2 at the top of the screen. A second cursor C2 is displayed at the end of the second character string. The second character string is currently one hiragana character. As will be described later, various characters such as hiragana, katakana, and alphanumeric characters (corresponding to the second character type of the present invention) are added to the second character string in response to the key being pressed by the user. The Rukoto.

  When receiving the key input, the CPU 100 first displays a character dial screen on the display surface 21b (S101), and then displays first and second character strings corresponding to the key input on the character dial screen (S102). ). At this time, the CPU 100 displays the character “0” corresponding to the pressed “0” key in the region R1 with reference to the key assignment table (FIG. 3A) in the numeric input mode. Further, the CPU 100 refers to the key assignment table in the kana input mode (FIG. 3B) and displays the character “WA” corresponding to the pressed “0” key in the region R2. Thus, two types of characters (first and second character strings) are displayed in parallel on the display surface 21b in response to a key input by the user.

  Note that the second character string “WA” is underlined as shown in FIG. As described above, the character string immediately after being input in the kana input mode is usually underlined (hereinafter, the underlined character string is referred to as an “indeterminate character string”). The user can perform an operation for converting an undetermined character string into another character string by Kana-Kanji conversion. When an operation for converting an undetermined character string is performed, the CPU 100 replaces the undetermined character string with another character string and displays it, and hides the underline. A character string for which Kana-Kanji conversion has been completed in this way is referred to as a character string in a “determined state”.

  The Kana-Kanji conversion is executed as follows, for example. As shown in FIG. 5B, prediction conversion results such as “Watanabe” and “I” based on the displayed character “WA” are displayed at the bottom of the region R2. That is, the CPU 100 predicts a word after conversion of the undetermined character string, and presents the predicted word on the display surface 21b. When the user performs an operation of selecting a desired word (hereinafter referred to as “conversion confirmation operation”), the CPU 100 replaces the unconfirmed character string with the focused word. In this way, kana-kanji conversion is executed.

  Next, in step S102, the CPU 100 executes a character / dial input reception / display process for receiving and displaying a further key input by the user. CPU 100 refers to a plurality of character allocation tables in accordance with an operation for character input performed by the user, and displays the first and second character strings in regions R1 and R2, respectively.

  When a new key input is made by the user, CPU 100 displays a dial character corresponding to the new key input in region R1 following the already displayed character (for example, “0”). In the region R1, the input mode for inputting the first character string is fixed to the number input mode.

  In addition, in region R2, CPU 100 displays a character corresponding to a new key input following the already displayed character (for example, “WA”). The default input mode in the region R2 is the kana input mode. In the region R2, the input mode for inputting the second character string can be changed to various input modes such as a numeric input mode and a kana input mode.

  Next, in step S103, the CPU 100 determines whether or not the call key 41 is pressed by the user. When the call key 41 is pressed (S103: YES), the process proceeds to a second character string and cursor position recording process S105 described later. On the other hand, when the call key 41 is not pressed (S103: NO), the process proceeds to the next step S104.

  In the process of step S104, the CPU 100 determines whether or not the character input is completed (S104). When the determination key 43 is pressed when the second character string is in the finalized state, the CPU 100 determines that the character input has been completed (S104: YES). When it is determined that the character input has been completed (S104: YES), the CPU 100 executes a second character string and cursor position recording process (S107) described later. When determining that the character input is not completed (S104: NO), the CPU 100 returns to the process of S102.

  In this way, the CPU 100 repeatedly executes the character / dial input acceptance / display process of S102 until it determines YES in the process of step S103 or S104.

  FIG. 6A is a diagram showing an example when a new key is input following the initial key input and a telephone number is input on the character dial screen.

  For example, in order to input a telephone number, the user follows a “0” key followed by a “3” key, a “1” key, a “5” key, a “1” key, a “5” key, a “9” key, When the “2” key, “6” key, “5” key and “3” key are pressed, the first character string “03151592653” is displayed in the region R1, and the first cursor C1 is displayed at the end thereof. The On the other hand, in the region R2, the second character string “Wasana Arana Hanasa” in an unconfirmed state is displayed, and a second cursor C2 is displayed at the end thereof.

  In the example shown in FIG. 6, the telephone number of the call destination is input to the area R1 by the user. In this case, the second character string displayed in the region R2 usually does not have a specific meaning.

<Processing related to the first character string>
When the user presses the call key 41 in the state where the telephone number is entered on the character dial screen as shown in FIG. 6A, the CPU 100 determines YES in S103, and the first character in step S105. Executes the process of recording the column and cursor position.

  In step S105, the CPU 100 stores, in the memory 101, data representing the first character string and the cursor position of the first cursor C1, that is, the additional position displayed in the region R1 immediately before the determination of YES in step S103. Are written in a predetermined area.

  Here, the cursor position (addition position) of the cursor displayed on a certain character string is expressed by, for example, the number of characters (integer of 0 or more) displayed between the head of the character string and the cursor position. Is done. In the example of FIGS. 5B and 6A, the cursor position of the first cursor C1 is 1 and 11, respectively.

When the process of step S105 is completed, the CPU 100 activates a dial input program (S106). As a result, the character / dial input program ends.
The dial input program is a program for accepting a key operation for inputting dial characters by a user and starting a call using the input character string as a telephone number of a call destination.

  FIG. 6B is a diagram for explaining the display contents on the display surface 21b when the dial input program is executed. The character string “03151592653” that is the same as the first character string in FIG. 6A is displayed in the character input area T1 (area surrounded by the alternate long and short dash line) at the bottom of the display surface 21b. The character string displayed in this way when the dial input program is executed is referred to as a “dial character string”.

  FIG. 7 is a flowchart showing the execution procedure of the dial input program.

  When the dial input program is activated, the CPU 100 reads the first character string written by the process of the previous step S105 from the memory 101 as the dial character string, and is also written by the process of the previous step S105. The cursor position is read from the memory 101 as the cursor position on the dial character string (S121).

  Next, the CPU 100 executes dial input screen display processing (S122). In step S122, the CPU 100 displays a screen for inputting a dial character string (hereinafter referred to as a “dial input screen”) as shown in FIG. Then, as shown in the figure, the CPU 100 displays the dial character string read from the memory 101 on the display surface 21b (S123). Then, the CPU 100 displays the cursor C3 at the cursor position on the dial character string read from the memory 101 (S124). Therefore, the cursor position of the cursor C3 in FIG. 6B is the same as the cursor position of the first cursor C1 in FIG.

  In the examples of FIGS. 6A and 6B, the first cursors C1 and C3 are displayed at the end of the character string. However, as described later, the cursor position may not be displayed at the end. For example, when the screen shown in FIG. 6A is displayed, the character “5” of the fourth character of the first character string in FIG. May be substituted. When this operation is performed, the first cursor C1 is displayed on the right side of the replaced character “4” as shown in FIG.

  In this case, when the user presses the call key 41 in a state where the first character string is displayed as shown in FIG. 8A, in the process of S105 in FIG. The first character string “031415926553” and the cursor position (= 4) of the first cursor C 1 are written into the memory 101. Then, the CPU 100 activates a dial input program (S106). When executing the dial input program, the CPU 100 displays a dial input screen as shown in FIG. 8B on the display surface 21b in steps S122 to S124. At this time, the cursor C3 displayed in the character display area T1 in FIG. 8B is displayed at the same position as the cursor position of the first cursor C1 in FIG. 8A (S124).

  Next, in step S125, the CPU 100 executes dial character editing processing. The CPU 100 accepts key input for dial character input and editing by the user, and adds the dial character corresponding to the pressed key to the cursor position of the cursor C3 of the dial character string. In this way, the dial character editing process of S125 is executed. This process is executed until it is determined in step S126 that the call key 41 is pressed by the user.

  If the user presses the call key 41 and determines that the call key 41 is pressed in step S126 (S126: YES), the CPU 100 activates a call program to start the call (S127). Thereby, the dial input program ends.

  Note that there may be a case where the user wants to start a call immediately after inputting the first character string in the area R1 of the character dial screen. In this case, the user may press the call key 41 twice continuously from the state where the character dial screen is displayed. If this key operation is performed, CPU100 will start the process of the transmission for a telephone call according to determination process S103 and S126.

<Processing related to the second character string>
FIG. 9 is a diagram showing an example when a new key is input following the first key input (see FIG. 5B) and a sentence is input on the character dial screen.

  The user presses the “0” key as shown in FIG. 5B to input a sentence instead of a telephone number, and then presses the “4” key once, the “5” key once, and “6”. When the key is continuously pressed four times and the “*” key is pressed once, the second character string “Watanabe” is displayed in an unconfirmed state in the region R2, as shown in FIG. 9A. At this time, the first character string “0456666 *” is displayed in the boundary area R1.

  The user can convert the unconfirmed character string “Watanabe” into “Watanabe” as shown in FIG. 9B, for example, by performing Kana-Kanji conversion. When the second character string is in the finalized state, the CPU 100 displays a character string “Chinese” indicating that the current input mode is the kana input mode at the bottom of the region R2, as shown in FIG. 9B. M1 is displayed. When the conversion confirmation operation is performed by the user, the CPU 100 hides the displayed region R1 as illustrated. Note that the region R1 is not necessarily hidden.

  As will be described later, when another input mode is set in the region R2, another character string is displayed at a position where the character string M1 is displayed. For example, when the input mode is the numeric input mode, the character string M1 “12” is displayed instead of “Chinese” (see FIG. 13A).

  After that, by repeating the key input and the conversion confirmation operation by the user, for example, the second character string composed of four character strings is displayed in the confirmed state in the region R2, as shown in FIG. The second cursor C2 is displayed at the end of the second character string.

  Returning to FIG. 4, as shown in FIG. 9C, when the user presses the enter key 43 in a state where the second character string is displayed in the region R <b> 2, the CPU 100 performs character input in the process of step S <b> 104. Is completed (S104: YES), and the second character string and cursor position recording process of S107 is executed.

  In step S107, the CPU 100 stores, in the memory 101, the second character string and the cursor position of the second cursor C2 displayed in the region R2 immediately before the determination in step S104 is YES, in the same manner as in step S105. Are written in a predetermined area.

  Next, the CPU 100 executes an application selection screen display process S108.

  FIGS. 10A and 10B are views showing an application selection screen.

  In the process of step S108, the CPU 100 displays a menu for the user to select a desired application, as shown in FIG. The CPU 100 displays a list in which 11 selectable applications are arranged on the display surface 21b. On the left side of each item, 11 number symbols (1 to 9, 0, *) corresponding to each application are respectively attached. In FIG. 10A, the first “Internet search” is focused.

  The first “Internet search” is an item for performing an Internet search using the second character string recorded in step S107 as a keyword.

  The second “keyword search” is an item for cross-searching contents such as music, games, news, blogs, and SNS using the second character string recorded in step S107 as a keyword.

  The third “transfer search” is an item for executing a search for transfer guidance such as a train using the second character string recorded in step S107 as a keyword.

  The fourth “map search” is an item for executing a search for displaying a map of the location and information on the location using the second character string recorded in step S107 as a keyword.

  The fifth “e-mail search” is an item for searching for e-mails sent and received by the user using the second character string recorded in step S107 as a keyword.

  The sixth “E-mail text” is an item for creating and sending an email using the second character string recorded in step S107 as the email text.

  The seventh “C mail text” is an item for creating and sending a message using the second character string recorded in step S107 as the text of the SMS (Short Message Service).

  The eighth “memo pad registration” is an item for recording on the memory 101 so that the user can refer to the second character string recorded in step S107 later.

  The ninth “dictionary lookup” is an item for searching the dictionary using the second character string recorded in step S107 as a keyword.

  The 0th “schedule registration” is an item for registering schedule management data using the second character string recorded in step S107 as a requirement.

  “Address book registration” of “*” is an item for registering data so that the second character string recorded in step S107 can be used as an address book application.

  When the CPU 100 displays the list of applications as described above, it executes the process of the next step S109.

  In S109, the CPU 100 stands by so as to be able to accept a key operation by the user. The user can move the focus to a desired item by performing a predetermined key operation. For example, when the UP key 44 or the DOWN key 45 is pressed, the CPU 100 moves the focus up and down in accordance with the pressed key.

  Next, in the process of step S110, the CPU 100 determines whether or not the user has performed an operation for determining an application to be started (S110). When the determination key 43 is pressed by the user, it is determined that the determination operation has been performed (S110: YES), and the process proceeds to the next step S111. If the determination key 43 is not pressed, the CPU 100 determines that the determination operation is not performed (S110: NO), and returns to the process of step S109.

  In this way, the CPU 100 repeatedly executes the input acceptance / display processing of the application selection operation while the operation for determining the application to be activated is not performed by the user (S110: NO) (S109).

  If YES is determined in the determination process of step S110 (S110: YES), the CPU 100 activates and executes the application selected by the user (the application focused when the enter key 43 is pressed) (S111). ). For example, when the user selects and determines the sixth “E-mail text”, the CPU 100 activates an e-mail application for creating and sending an e-mail.

  The case will be described below by taking the case where the sixth “E-mail body” in FIG. 9 is selected (see FIG. 10B) as an example.

  FIG. 11 is a flowchart showing the procedure of the email text editing process related to the email application. FIGS. 12A and 12B are views respectively showing a main screen and an e-mail text editing screen when an e-mail application is executed.

  When the e-mail application is activated, the CPU 100 reads the second character string (see step S107) recorded in the memory 101 as an e-mail text. Next, the CPU 100 displays a main screen shown in FIG. 12A for creating and sending an e-mail on the display surface 21b.

  As shown in FIG. 12A, four icons are displayed in a vertical line on the display surface 12b. The second icons displayed as “To” and “Subject” are icons for entering the destination mail address and subject. The third icon on which the symbol of the clip is displayed is an icon for designating an attached file. The icon displayed as “Text” arranged at the bottom is an icon for inputting an e-mail text. In FIG. 12A, the icon displayed as “To” is focused.

  Under the icon displayed as “Text”, the CPU 100 displays the second character string read from the memory 101 on the display surface 21b as an e-mail body.

  In the state where the main screen is displayed as shown in FIG. 12A, the user can start editing the e-mail text. The e-mail text editing process for editing the e-mail text starts when the user moves the focus to the icon displayed as “Text” and presses the enter key 43.

  When an operation for starting editing is performed by the user, the CPU 100 displays a screen for editing an e-mail text (S131). Then, the CPU 100 displays the second character string read from the memory 101 as an e-mail text in the finalized state in the character input area T2 (area surrounded by a one-dot chain line) on the display surface 21b (S132).

  In the lower part of the display surface 21b, a character string M2 “Khan” is displayed to notify the user that the current input mode is the kana input mode.

  In the next step S133, the CPU 100 reads the cursor position written in the memory 101 in the process of step S107 of FIG. 4 as the cursor position on the e-mail body (S133). Then, as shown in FIG. 12B, the CPU 100 displays the cursor C4 at the cursor position read from the memory 101 on the e-mail body (S134).

  As shown in FIG. 12 (b), the e-mail text displayed on the e-mail text editing screen and the cursor position of the cursor C4 are the second character string and the second cursor C2 displayed in FIG. 9 (c). Are the same as the cursor positions.

  Next, the CPU 100 executes processing for editing the mail text (S135).

  During the editing process, the CPU 100 determines whether or not a key operation for completing editing of the electronic mail text has been performed by the user (S136). When the user completes editing of the e-mail text, the user places the e-mail text in a finalized state and presses the enter key 43.

  When the determination key 43 is pressed in a state where the email text is displayed in a finalized state (S136: YES), the CPU 100 ends the email text editing process of FIG. 11 and includes the edited email text. A screen (see FIG. 12A) is displayed.

  In this way, in the electronic mail application, the second character string and the cursor position recorded in S107 of FIG. 4 are read, and the second character string and the cursor position are taken over in the electronic mail text editing process.

  FIG. 13A is a diagram showing a character dial screen in a state where the second cursor C2 is not at the end of the second character string. FIG. 13B is a diagram showing an email text editing screen when the email application is activated from the state where the character dial screen is shown in FIG.

  In FIG. 9C and FIG. 12B, the second cursor C2 and the cursor C4 are displayed at the end of the second character string and the e-mail body, respectively. However, as described below, the cursor position may not be displayed at the end. For example, when the screen shown in FIG. 9C is displayed, the user may perform an operation of replacing the character “1” on the third line of the second character string with the character “2”. obtain. In this case, as shown in FIG. 13A, the second cursor C2 is displayed on the right side of the replaced character “2”.

  Even when the user presses the enter key 43 when the second cursor C2 is displayed in the middle of the second character string as shown in FIG. 13A, the CPU 100 causes the second character string and The cursor position of the second cursor C2 is written into the memory 101 (S107). When the user performs a key operation to start the e-mail text editing process, a display as shown in FIG. 13B is made. That is, even in this case, the cursor position of the cursor C4 on the body of the electronic mail in FIG. 13B is the same as the cursor position of the second cursor C2 on the second character string in FIG. .

  As described above, the cellular phone 1 according to the present embodiment has a function of simultaneously displaying the first and second character strings in parallel according to the operation of the dial key group 50 by the user in the character / dial input program. Thereafter, either one of the first and second character strings is selected in accordance with a predetermined operation input by the user, and an application corresponding to the selected character string (dial input program, e-mail application, etc. ( (See FIG. 10)) is performed. The selected character string is displayed again when the operation screen (dial input screen, e-mail text editing screen) of the activated application is displayed. At this time, the cursor is displayed on the character string displayed again at the same position as the cursor on the character string displayed on the character dial screen.

  With such a configuration, when editing a character string (one character string selected from the first or second character strings) input by the user on the character dial screen at the time of execution of the application, the user is as if character dialing is performed. It is possible to perform the editing operation without paying attention to the difference in cursor position as if the character strings on the screen and the operation screen can be continuously edited. For this reason, the number of key operations for cursor movement performed by the user during the editing is reduced. Further, the time required for the editing operation by the user is shortened by reducing the number of key operations. Therefore, the convenience of various applications (dial input program, e-mail application, etc.) started following the character / dial input program is improved.

<Modification 1>
In the above embodiment, when the process of step S107 in FIG. 4 is executed, the memory 101 stores the second character string displayed in the area R2 of the character dial screen and the cursor position of the second cursor C2. Data has been written. On the other hand, in this modified example, when the CPU 100 executes the process of step S107, in addition to the cursor position of the second character string and the second cursor C2, the input immediately before being determined as YES in S104. Data representing the mode is also recorded in the memory 101. For example, in the example shown in FIG. 13A, a character string M1 “12” indicating that the input mode is the numeric input mode is displayed below the region R2. Therefore, in this example, the input mode data written to the memory 101 in step S107 is data representing the numeric input mode.

  FIG. 14A is a flowchart showing the procedure of the execution process of the e-mail application according to this modification. FIG. 14B is a diagram showing an email text editing screen in the email application according to this modification.

  The flowchart shown in FIG. 14A is obtained by changing the processing content in step S133 to S133a in the flowchart shown in FIG. 11 and adding a new process S137 after the process in step S134.

  In this modified example, when the e-mail text editing process of FIG. 11 is started, the CPU 100 adds the second character string (e-mail text) and its cursor position to the memory 101 in the process of step S133a. The data of the stored input mode (in the case of the example of FIG. 13A, a numeric input mode) is also read.

  After executing the cursor display process in step S134, the CPU 100 sets the input mode read from the memory 101 as the input mode of the currently executed e-mail text editing process in the next step S137. In the above example, the current input mode is set to the numeric input mode as indicated by the character string M2 “12” in FIG.

  As described above, in this modified example, not only the cursor position but also the input mode is inherited when the application is executed. That is, when an application selected and activated on the application selection screen (e-mail application) is executed, when the same character string (e-mail body) as the second character string input in the second region R2 is edited, The current input mode is set to be the same as the input mode immediately before the input of the second character string in the second region R2 is completed.

  With such a configuration, when editing a character string input by the user on the character dial screen at the time of execution of the application, as if the user can continuously edit the character string on the character dial screen and the operation screen. The editing operation can be performed without paying attention to the difference in input mode. For this reason, when the user edits the character string during execution of the activated program, the number of key operations for changing the input mode performed by the user is reduced. Further, the time required for the editing operation by the user is shortened by reducing the number of key operations. Therefore, the convenience of various applications started following the character / dial input program is improved.

<Modification 2>
In the present modification example, the CPU 100 executes an input history of the first or second character string input on the character dial screen in addition to the cursor position, and thereafter an application (dial input program, e-mail application, etc.). Take over and use. The “input history” is data representing a history of editing (character input, deletion, etc.) operations performed on the target character string. The CPU 100 refers to the input history in order to perform an undo process in accordance with a predetermined operation performed by the user.

  For example, the input history is data in which target character strings are arranged in association with a time order every time an editing operation is performed or a predetermined time elapses. The undo process is a process in which the current character string to be processed is returned to the last character string in the time order included in the input history. When the undo process is executed once, the character string with the last time order included in the input history is deleted from the input history.

  With respect to the first character string, in the present modification example, when the process of step S101 is executed, the CPU 100 causes the memory 101 to display the first character string and the first character string displayed in the region R1 of the character dial screen. In addition to the cursor position of the cursor C1, the input history of the first character string is stored. Then, when the dial character string and cursor position reading process in step S121 is executed, the CPU 100 stores the input history of the first character string stored in addition to the first character string and the cursor position from the memory 101. Also read.

  The CPU 100 sets the read input history as the initial input history when editing the dial character string. Then, the CPU 100 executes the dial character string editing process of S125 so that the user can accept an undo operation.

  For example, as described above, after the user replaces the fourth character “5” of the first character string in FIG. 6A with the character “4” (see FIG. 8A), The case where the dial input program is activated (see FIG. 8B) may occur. In this modification, when a predetermined operation for undoing is performed by the user, the CPU 100 refers to the set input history and performs the editing performed by the user for the first character string last. Cancel the operation and restore it. Specifically, in the above example, when a predetermined operation for undo is performed while the dial input screen is displayed as in the example shown in FIG. 8B, the CPU 100 refers to the input history. Then, the replaced character “4” is returned to “5” and displayed.

  Similarly, for the second character string, in this modified example, when the process of step S107 is executed, the CPU 100 displays the second character displayed in the area R2 of the character dial screen in the memory 101. In addition to the column and the cursor position of the second cursor C2, the input history of the second character string is stored. Then, in the process of reading the cursor position in step S133, the CPU 100 reads the cursor position from the memory 101 and also reads the input history of the stored second character string.

  When executing the e-mail application selected and activated by the user on the application selection screen (FIG. 6B), the CPU 100 sets the read input history as the initial input history at the time of the e-mail text editing process. To do. Then, the CPU 100 executes the mail body text editing process of S135 so that the user can accept an undo operation based on the set input history.

  In this manner, the CPU 100 records the input history of the first or second character string in addition to the first or second character string and the cursor position, and subsequently executes an application (dial input program, e-mail application). Etc.). That is, the input history recorded in the memory 101 is applied to the character string displayed in the character input area of the application. As a result, when the program is executed, the user can cancel the editing applied to the first or second character string back to the editing performed on the character dial screen, and the application can be more comfortably performed. Can be used.

  As described above, also in this modified example, when editing the character string input by the user on the character dial screen when the application is executed, it is as if the user can continuously edit the character string on the character dial screen and the operation screen. In addition, the editing operation can be performed while performing an undo operation using the input history of the input operation on the character dial screen on the operation screen of the application.

  Note that the CPU 100 may perform not only a single undo operation as described above, but also a process of returning the character string to a plurality of times and displaying it according to the number of undo operations performed by the user. .

  Although the present embodiment has been described above, the present invention is not limited to the above embodiment, and the embodiment of the present invention can be variously modified in addition to the above embodiment. is there.

<Others>
In the above embodiment, when a character string (one of the first and second character strings) taken over from the character dial screen is displayed in an editable state in the dial input program and the e-mail application. It has been described that the cursor is displayed at the same position as the cursor position of the cursor displayed on the one character string on the character dial screen. However, the present invention can also be applied when other applications are executed. For example, the present invention can be applied when an application other than the electronic mail application displayed in the list of FIG. 10A is executed. That is, in another application, when the second character string inherited from the character dial screen is displayed in an editable state, the cursor is positioned at the same position as the cursor on the second character string on the character dial screen. Is displayed.

  Moreover, when displaying the application selection screen of FIG. 10, the order of items to be displayed may be changed according to the first or second character string input to the character dial screen. For example, when a character string that is highly likely to be the body of an e-mail is input, such as a long second character string, the sixth “E-mail body” may be displayed at the top.

  In the above embodiment, two types of character strings (first and second character strings) are displayed on the character dial screen. The character strings displayed on the character dial screen need not be limited to two types. For example, in addition to the first and second character strings described above, the CPU 100 may display a third character string consisting of lowercase letters. In this case, the CPU 100 refers to the key assignment table for displaying lowercase letters and displays the lowercase letters corresponding to the pressed key on the character dial screen. For example, an application that handles an e-mail transmission destination address may be executed so that the third character string can be edited and the cursor position is inherited. Alternatively, when key input is accepted from the state of the standby screen, an input screen for inputting one character string may be displayed on the display surface 21b instead of a character dial screen for inputting two character strings. .

  In the present embodiment, the first and second character strings are input by operating the key operation unit 11. However, the present invention is not limited to this, and a software keyboard may be used as the key operation unit. In this case, a touch sensor is provided on the display surface 21b, and the CPU 100 displays a software keyboard on the display surface 21b. The user can input the first and second character strings by touching and operating the display surface 21b while looking at the software keyboard.

  In the present embodiment, the cursor is always displayed at an additional position for adding a character on the character string. However, in the present invention, the cursor need not always be displayed on the display surface. For example, when the added position is at the end of the character string, the cursor may not be displayed. In this case, for example, the cursor is displayed only when the additional position is moved to a position other than the end of the character string by pressing the LEFT key 47 or the like.

  In the present embodiment, the added positions of the characters of the first and second character strings are stored in the memory 101 (S104, S107). However, only the additional position of one of the first and second character strings may be stored in the memory 101. For example, only the character addition position for the first character string for a call may be stored in the memory 101.

  In the above embodiment, the foldable mobile phone 1 is used, but a mobile phone 1 of a slide type or a straight type can also be used. Further, instead of the mobile phone 1, a device with an electronic mail function such as a mobile terminal device such as a PDA or an information processing device such as a personal computer can be used.

  In addition, the embodiment of the present invention can be variously modified as appropriate within the scope of the technical idea shown in the claims. For example, some or all of the above embodiments can be combined.
