A CPU (Central Processing Unit) 14 controls various connected units based on a control program stored in a ROM 16 to control various functions (a mobile phone function, a mail transmission / reception function, a mail text creation function) provided in the mobile phone 1. , Character clear function, etc.). That is, in response to various key input instructions from the input unit 17, the CPU 14 reads a corresponding control program from the ROM 16, expands and executes the control program on the work area of the RAM 15, and controls the connected units to perform various functions (portable operation). Telephone function, e-mail transmission / reception function, e-mail text creation function, character clear function, etc.).
[0016]
Specifically, the CPU 14 recognizes an input signal of a character input by the operation of the input unit 17 by the operator, and temporarily associates the specified character with predetermined display position data of the display unit 18 and stores it in the RAM 15. It is stored and displayed at a predetermined display position on the display unit 18.
[0017]
When detecting an input signal of a short press of the clear key C (delete key) on the character input screen as a range designating means, the CPU 14 recognizes the position of the cursor in the character input screen as a cursor position recognizing means. Delete the character specified by the cursor position.
[0018]
When the CPU 14 detects a long press input signal of the clear key C (delete key) during character input on the character input screen as a display control means, the CPU 14 displays a clear display in the navigation display area G2 (described later) of the display unit 18. The menu items are displayed, and various items for clearing the displayed characters are made executable as range designation means.
[0019]
More specifically, the CPU 14 recognizes the position of the cursor CS as a cursor position recognizing means, and stands by. Then, when the CPU 14 detects a press signal of the menu key M during the standby, the CPU 14 specifies the range of all characters being displayed as a range to be cleared, and similarly, the CPU 14 of the up key 17 d If the press signal is detected, the entire character string (including the character specified by the cursor key) input before the position of the cursor CS is specified as a range, and if the press signal of the down key 17e is detected, When the entire range of the character string input after the position of the cursor CS is designated and a press signal of the left key 17f is detected, the character string input before the position of the cursor CS in the line where the cursor CS is located All, in other words, all the character strings located on the left side of the cursor in the line are designated, and when the press signal of the right key 17g is detected, the character string in the line where the cursor CS is located All string entered after the position of the Cursor CS, i.e., specifying a range of any string on the right side of the cursor keys in the row.
[0020]
Further, the CPU 14 deletes the characters included in the range specification from the display unit 18 as a deletion unit, and redisplays the screen after the deletion.
[0021]
A RAM (Random Access Memory) 15 forms a work area for developing a control program read from the ROM 16 and executed by the CPU 14, data being processed, and the like. The RAM 15 also temporarily stores screen data at the time of various screen transitions to be described later, characters whose range is specified in association with the display position data on the display unit 18, and the like.
[0022]
A ROM (Read Only Memory) 16 is constituted by a flash ROM or the like, and stores various control programs executed by the CPU 14 and a control program for executing the character clear function. Also, screen data at the time of various screen transitions described later is stored.
[0023]
The input unit 17 functions as an input unit, and as shown in FIG. 2, a ten-key group 17a, a power / on-hook key 17b, an off-hook key 17c, an up key 17d, a down key 17e, a left key 17f, a right key 17g, a soft key S1, S2, a menu key M, and a clear key C are provided, and input signals corresponding to respective key input operations are output to the CPU 14.
Specifically, the numeric keypad group 17a is used for inputting a telephone number and a character string (kana characters, katakana, English characters, etc.), and the power / on-hook key 17b is used for turning on / off the mobile phone 1 and ending a call or character input. And the off-hook key 17c is used to input a call. The up / down / left / right keys 17d, 17e, 17f, and 17g (predetermined operation keys and direction keys) are used for inputting movement of an input position with a cursor on a telephone screen, a mail input screen, and the like, and for setting a preset character clear range. The software keys S1 and S2 (predetermined operation keys) are used to input software functions assigned in advance on the telephone number input screen, the mail input screen, and the like, and the menu key M is set in advance in the telephone mode, the mail input mode, etc. The clear key C (delete key) is used to move the entered menu, and to cancel the input instruction on the telephone number input screen, mail input screen, etc., to enter the clear menu screen and to return from the clear menu screen Used for etc.
[0024]
The display unit 18 functions as a display unit, and is display-controlled by a display control signal input from the CPU 14, and inputs a telephone screen, a mail input screen, a clear processing setting screen, and the like of the mobile phone 1 from the key input unit 3. And displays the information input by key on each of the screens.
Further, as shown in FIG. 3, on various display screens such as a telephone screen and a mail input screen, a main display area G1 in which main items are displayed and an instruction input for performing various functions on the main display unit are navigated. A navigation display area G2 is formed.
[0025]
In particular, in the navigation display area G2, for example, when a mail text is displayed in the main display area G1, selection keys for input characters such as kanji input, kana input, and alphanumeric input, and a transition instruction key to a menu screen In addition to displaying Kanji conversion candidates, key information for navigating to the operator which key should be pressed to execute the clearing process is displayed as a clear menu.
Specifically, as shown in FIG. 3, for example, the up / down / left / right selection display icons 3a displayed in the main display area G1 are used to move the cursor position, using the up key 17d, the down key 17e, and the left key 17f. , The right key 17g may be operated, and similarly, the menu 3b is depressed by pressing the soft key S1 to transit to the menu screen, and the character type display 3c is displayed by switching the character type. This indicates that the soft key S2 should be pressed.
[0026]
The speaker 19 converts an audio signal input from the CPU 14 into audio and outputs the audio.
The microphone 20 converts the transmission voice of the user into a transmission voice signal and outputs the signal to the CPU 14.
[0027]
Next, the character clearing process of the input character executed by the mobile phone 1 having the above configuration will be described with reference to a flowchart shown in FIG. 4 and an input screen transition diagram shown in FIG.
[0028]
First, when the menu key M or the like of the input unit 17 is pressed by the operator of the mobile phone 1, a mail creation instruction signal is input, and the CPU 14 that detects the mail creation signal inputs characters for creating a mail. A screen is displayed on the display unit 18 (Step S1).
[0029]
Next, the CPU 14 causes the display unit 18 to display a character input screen 501 as shown in FIG. 5, for example.
Here, in the navigation display area G2 of the character input screen 501, an up / down / left / right selection display icon 5a for navigating a key operation for moving the position of the cursor CS in the main display area G1, and a menu screen by pressing the soft key S1. Menu icon 5b for navigating the transition to, a character type (Kan) icon 5c for indicating the currently selected character type, and for navigating the change of character type by pressing soft key S2, and input to main display area G1 The remaining character number 5d indicating the number of remaining characters is displayed.
[0030]
In the above state, when a character is input by the operator pressing a predetermined key of the input unit 17, the CPU 14 displays the character corresponding to the input key on the display position data of the display unit 18. Are temporarily stored in the RAM 15 in association with the above, and the operation of displaying the data in the main display area G (step S2) is repeated. At this time, the CPU 14 stores the position data of the cursor CS indicating the input position in the RAM 15, and updates the data in the RAM 15 as needed every time the cursor CS moves according to the operation of the operator.
[0031]
Next, the CPU 14 determines whether or not the clear key C has been short-pressed by the operator (step S3). When it is determined that the clear key C has been short-pressed (step S3: Yes), the process proceeds to step S4, where the short press is performed. If it is determined that it has not been performed (step S3: No), the process proceeds to step S6.
[0032]
In step S4, the CPU 14 recognizes the position of the cursor CS on the character input screen 501. Next, the CPU 14 determines that the character specified by the cursor CS (for example, “large”) is within the clear range, executes the deletion process, and displays the post-deletion screen 502 on the display unit 18 (step S5). .
Here, the CPU 14 updates the display position data of each character to be displayed stored in the RAM 15, and then, on the after-deletion screen 502, the position of the cursor CS does not change and the character next to the deleted character (for example, , "Variable"), and updates the number of characters 5d. In the case of the number of characters 5d, two full-width characters and one half-width character are displayed. Since one full-width character is deleted, the remaining number of characters 5d is increased by two. After the deletion of one character, the process proceeds to step S2. Therefore, the mail text creation processing can be executed by repeating the text input, display, and clear processing.
[0033]
On the other hand, in step S6, the CPU 14 determines whether or not the clear key C has been long-pressed. If an input signal for long-pressing is detected (step S6: Yes), the CPU 14 shifts to step S7 to perform long-pressing. If the input signal cannot be detected (step S6: No), the process returns to step S2.
[0034]
In step S7, the CPU 14 displays a clear menu as shown on the character input screen 503 in FIG. 5 in the navigation display area G2. A clear menu 5e is displayed in the upper part of the navigation display area G2. Specifically, in order to delete all the characters displayed in the main display area G1, it is necessary to press the menu key M in order to perform a full clear. A “M all clear” icon 5f to gate and a “up / down / left / right select” icon 5g that navigates to press the up / down / left / right keys 17d, 17e, 17f, and 17g to specify the direction of the character to be cleared are included. Is provided.
[0035]
Further, the CPU 14 recognizes the position of the cursor CS on the character input screen 503 (Step S8).
[0036]
Next, the CPU 14 determines whether or not the menu key M has been pressed by the operation of the input unit 17 by the operator (step S9). If it is determined that the menu key M has been pressed (step S9: Yes), the process proceeds to step S10. If it is determined that the button has not been pressed (step S9: No), the process proceeds to step S11.
[0037]
In step S10, when the menu key M is pressed, the CPU 14 recognizes that all the characters displayed in the main display area G1 of the character input screen 503 are within the clear range, executes a deletion process of all the characters, and executes the RAM 15 The character input screen 504 is displayed in the main display area G1 after updating the display position data of each character to be displayed stored in the main display area G1. At this time, the number of remaining characters 5d in the navigation display area G2 is also updated and displayed, and the navigation display area G2 is changed from a clear menu to a normal menu. After step S10, the process proceeds to step S2.
[0038]
In step S11, the CPU 11 determines whether or not the up key 17d has been pressed. If it is determined that the up key 17d has been pressed (step S11: Yes), the process proceeds to step S12, where the up key 17d is pressed. If it is determined that it has not been performed (step S11: No), the process proceeds to step S13.
[0039]
In step S12, the CPU 14 determines, as the clear operation associated with the up key 17d, the cursor CS position including the character specified by the cursor CS (for example, “large”) among the characters displayed in the main display area G1. All the characters displayed earlier are recognized as the clear range, and the clear range is deleted. Then, the CPU 14 updates the display position data of each character to be displayed, which is stored in the RAM 15, and causes the main display area G <b> 1 of the character input screen 505 to display the screen after the deletion. At this time, the display of the remaining number of characters 5d in the navigation display area G2 has also been updated, and the navigation display area G2 is in the normal menu display.
Then, the process proceeds to step S2 after step S12.
[0040]
In step S13, the CPU 14 determines whether or not the down key 17e has been pressed. If it is determined that the down key 17e has been pressed (step S13: Yes), the process proceeds to step S14, and if not, the CPU 14 determines that the down key 17e has not been pressed. If it is determined (Step S13: No), the process proceeds to Step S15.
[0041]
In step S14, the CPU 14 performs, as the clear operation associated with the down key 17e, the cursor CS including the character specified by the cursor CS (for example, “large”) among the characters displayed in the main display area G1. All characters displayed after the position are recognized as a clear range, and the clear range is deleted. Then, the CPU 14 updates the display position data of each character to be displayed stored in the RAM 15 and displays the character input screen 506 in the main display area G1 as the screen after deletion. At this time, the display of the remaining number of characters 5d in the navigation display area G2 has also been updated, and the navigation display area G2 is in the normal menu display.
Then, the process proceeds to step S2 after step S14.
[0042]
In step S15, the CPU 14 determines whether or not the left key 17f has been pressed. If it is determined that the left key 17f has been pressed (step S15: Yes), the process proceeds to step S16, and if not, the CPU 14 determines that the left key 17f has not been pressed. When it is determined (step S15: No), the process proceeds to step S17.
[0043]
In step S16, as a clear operation associated with the left key 17f, the CPU 14 displays the character displayed in the main display area G1 on the line where the cursor CS is located, before (to the left of) the cursor CS position. All the characters that have been set are recognized as the clear range, and the clear range is deleted. At this time, the character specified by the cursor CS (for example, “large”) is included in the clear range. Then, the CPU 14 updates the display position data of each character to be displayed stored in the RAM 15 and displays the character input screen 507 in the main display area G1 as the screen after deletion. At this time, the display of the number of characters 5d in the navigation display area G2 has also been updated, and the navigation display area G2 is in the normal menu display.
Then, the process proceeds to step S2 after step S16.
[0044]
In step S17, the CPU 14 determines whether or not the right key 17g has been pressed. If it is determined that the right key 17g has been pressed (step S17: Yes), the CPU 14 proceeds to step S18, and determines that the right key 17g has not been pressed. When it is determined (step S17: No), the process proceeds to step S19.
[0045]
In step S18, the CPU 14 displays, as a clear operation associated with the right key 17g, a character displayed in the main display area G1 on the line where the cursor CS is located, after the cursor CS position (right side). All the characters that have been set are recognized as the clear range, and the clear range is deleted. At this time, the character designated by the cursor CS (for example, “large”) is included in the clear range. Then, the CPU 14 updates the display position data of each character to be displayed stored in the RAM 15, and then displays the character input screen 508 in the main display area G1 as the screen after deletion. At this time, the display of the number of characters 5d in the navigation display area G2 has also been updated, and the navigation display area G2 is in the normal menu display.
Then, the process proceeds to step S2 after step S18.
[0046]
In step S19, the CPU 14 determines whether the clear key C has been pressed again. At this time, either long press or short press of the clear key C may be performed.
If the CPU 14 determines that the clear key C has been pressed (step S19: Yes), the CPU 14 determines that an instruction to stop execution of the clear menu has been issued, and displays the clear menu in the navigation display area G2 from the clear menu display to the normal menu. The content is updated, the character input screen 501 is displayed on the display unit 18, and the process returns to step S2. On the other hand, when determining that the clear key C has not been pressed (step S19: No), the CPU 14 proceeds to step S9 and waits until any key for executing the clear menu item is input.
[0047]
As described above, the process of steps S1 to S19 is repeated to create a text of the mail, and when a predetermined key (not shown) for transmitting a text is pressed, the text creation process ends.
[0048]
As described above, according to the present embodiment, a predetermined operation key is associated with a character clear operation, so that a character string in a predetermined range can be easily deleted at the time of text creation. Therefore, the trouble of deleting each character can be omitted, and the efficiency of text creation can be improved.
[0049]
In particular, since the clear range and its direction are associated with the up, down, left, and right direction keys 17d to 17g, the clear operation is easy to understand.
[0050]
In the above example, the key, the range for clearing the key, and the direction are set in advance. However, if any key is pressed, the range (the number of characters, etc.) and the character string in the direction are determined. It is assumed that the user can set whether to perform the clearing process.
[0051]
As a specific setting method, for example, when a setting item is selected from a menu by an operator, a setting screen for clear processing is displayed on the display unit 18 under the control of the CPU 14. Therefore, the operator sets the clear range (for example, before or after the cursor as described above, or in units of lines, in units of punctuation marks, units of phrases, units of words, units of paragraphs, etc.) and the direction of the range, that is, the cursor position. The CPU 14 selects which operation key is to be used to execute the clear process including before and after, so that the CPU 14 stores the setting data in which the contents of the clear process are associated with the operation keys for executing the clear process. It is stored in a memory (not shown).
When the operator designates an operation key associated with the content of the clearing process, the CPU 14 executes the clearing process based on the setting data.
[0052]
As described above, since the operator can set the clearing process, the usability of the operator is further improved.
[0053]
The description according to the present embodiment is an example of a suitable portable communication terminal according to the present invention, and the present invention is not limited to this.
For example, in the present embodiment, an example in which the present invention is applied to a mobile phone is given, but the present invention is not limited to this. For example, a mobile personal computer, PDA, PHS, It is applicable to general mobile communication.
[0054]
Further, the description has been made in the character input processing in the mail creation. However, the present invention can be applied to any character input such as a telephone directory name input.
[0055]
【The invention's effect】
