Description

  The present invention relates to a portable terminal device that includes an operation unit such as a numeric keypad and a display unit such as an LCD (liquid crystal display) and can display characters input from the operation unit on the display unit.

  Conventionally, there has been a portable terminal device that includes a display unit such as an LCD (liquid crystal display) and an operation unit, and can display characters input from the operation unit on the display unit (see FIG. 1).

  Such a portable terminal device has a numeric keypad for inputting numbers “1” to “9” and “0” in the operation unit, and each numeric key of the numeric keypad has such a number. In addition, a plurality of characters are assigned to each type of characters such as kana characters and English characters. For example, the “2” key is assigned the kana characters “ka”, “ki”, “ku”, “ke”, “ko”, and the English letters “A”, “B”, and “C”. It has been.

  For this reason, such a portable terminal device is selected after selecting one of input modes such as “kana character input mode” for inputting kana characters and “alphabet input mode” for inputting English characters. , That type of characters are to be entered.

  Then, in response to the order of a plurality of characters assigned to each key, the character to be displayed on the display unit can be input by pressing the key a predetermined number of times. Yes.

  In such a portable terminal device, if you operate the numeric keypad while selecting the wrong input mode, a character of a different type from the character that the user tried to input will be input. Then, you must select the correct input mode and enter the character again.

  Therefore, even if the input mode is selected by mistake and the character input operation is performed, a function that can convert the character into another input mode corresponding to the operation of the numeric keypad when the character is input is provided. Thus, there is a portable terminal device that improves the operation efficiency of character input (see, for example, Patent Document 1).

  On the other hand, there has been a portable terminal device having a copy and paste function that can improve the operation efficiency of character input, similar to the above-described function that converts input characters into characters in other input modes.

  This copy-and-paste function temporarily operates on the same character string as the character string in an arbitrary range specified by the user's operation from the entire character string displayed on the display unit. A function to store (copy) and paste (paste) a temporarily stored character string to this location when an operation is performed to specify another arbitrary location from the entire displayed character string. It is.

  In a series of operations when using such a copy and paste function, an operation for specifying an arbitrary range from the entire character string as a target of subsequent operations is performed during character input operations. This operation is frequently used even when other functions different from the copy and paste function are used.

  The operation to specify a character string in an arbitrary range from the entire character string is performed by moving the cursor in the display unit with the direction specification key such as a cross key in the operation unit, and at the beginning and end of the specified range. The range is selected by specifying the character.

Then, as shown in FIG. 14, when an arbitrary range is designated by the first and last characters from the character string in the screen 1 displayed on the display unit, the designated range is displayed in reverse video. It is like that.
Japanese Patent Laid-Open No. 2002-366288

  However, the conventional copy-and-paste function of the portable terminal device as described above allows the cursor to be moved by a direction designation key such as a cross key when a range to be designated from a character string is wide. There was a problem that the number of operations increased.

  Therefore, in view of the above problems, the present invention provides a portable terminal that can be specified with a small number of operations even when the range to be specified is wide when specifying an arbitrary range from the character string displayed on the display unit. It is an object to provide an apparatus.

In order to solve the above problems, the mobile terminal device of the present invention
An operation unit having a numeric keypad;
A display unit for displaying a character string input from the operation unit;
When an arbitrary range of a character string output to the display unit is input from the numeric keypad for the number of rows and columns of the first and last characters, control is performed so that this range is designated as an operation target. And a control unit.

The portable terminal device of the present invention is
The operation unit includes a direction designation key,
The control unit operates the direction designation key when the number of lines and the number of columns of the first and last characters are input from the numeric keypad in an arbitrary range of the character string output to the display unit. In this case, control is performed so that the character string is scrolled in the direction designated by the operation of the direction designation key.

  In the mobile terminal device of the present invention, the display unit displays a character string input from the operation unit within a predetermined region of the display unit, and each character in the character string outside the predetermined region. The number of rows and columns corresponding to is displayed.

  In the mobile terminal device of the present invention, when the control unit scrolls the character string of the display unit in the direction specified by the operation of the direction specifying key, the number of lines displayed outside the predetermined area And the number of columns is controlled to be scrolled according to the character string.

  In the mobile terminal device of the present invention, the control unit inputs the number of rows or columns of any of the first character or the last character from the numeric keypad for an arbitrary range of the character string output to the display unit. In this case, all the characters belonging to the inputted number of rows or columns are controlled to be displayed by a display method different from that of other rows.

  According to such a portable terminal device, when an arbitrary range is specified from the character string displayed on the display unit, it can be specified with a small number of operations even if the specified range is wide.

  Hereinafter, embodiments of a mobile terminal device according to the present invention will be described in detail with reference to the drawings. FIGS. 1 to 13 are diagrams which are referred to for explaining a mobile phone 2 (corresponding to a mobile terminal device) according to an embodiment of the present invention.

  As shown in FIG. 1, the mobile phone 2 includes a display unit 4 and an operation unit 6 in the same manner as a conventional mobile terminal device. The operation unit 6 includes a numeric keypad 6a, a cross key 6b as a direction designation key, A hook-off key 6c and a hook-on key 6d are arranged.

  FIG. 2 is a block diagram showing a circuit configuration of the mobile phone 2. In addition to the display unit 4 and the operation unit 6, the mobile phone 2 includes a communication unit 8 that performs wireless communication, an audio unit 10 that performs audio processing, a storage unit 12, and a control unit 14 that controls these.

  The audio unit 10 is connected to a speaker 10a and a microphone 10b. Here, since the communication unit 8, the audio unit 10, the speaker 10a, and the microphone 10b operate in the same manner as a conventional mobile phone, the description thereof is omitted.

  As shown in FIG. 3, the storage unit 12 includes a copy character string storage buffer 12a, a copy start point row number storage buffer 12b, a copy start point column number storage buffer 12c, a copy end point row number storage buffer 12d, and a copy end point column number storage buffer. 12e, an input character string storage buffer 12f, and an input character string display attribute storage buffer 12g are provided.

  The input character string storage buffer 12f stores the character string input by operating the numeric keypad 6a, and the character string stored in the input character string storage buffer 12f is displayed on the display unit 4. It has become.

  Further, the input character string display attribute storage buffer 12g stores the attributes for each character in order with respect to the character string displayed on the display unit 4. For example, for a character that is normally displayed in full-width on the display unit 4, “00” is set as the attribute of this character, and “FF” is set if the character is displayed in reverse video in full-width. It is like that.

  The copy start point row number storage buffer 12b, the copy start point column number storage buffer 12c, the copy end point row number storage buffer 12d, and the copy end point column number storage buffer 12e are displayed on the display unit 4 as will be described later. When specifying an arbitrary range from the character string of, when entering the number of rows and columns of the first character (start point) and the last character (end point) of this arbitrary range for the entire character string, These are memorized.

  Further, the copy character string storage buffer 12a stores a character string in an arbitrary range designated by the user from the character string displayed on the display unit 4 by a control operation of the control unit 14 to be described later.

  Next, based on the flowcharts of FIGS. 4 to 6, the control operation of the control unit 14 when an operation for designating a range to be copied from the character string displayed on the display unit 4 is performed will be described. A character string output screen 20 displayed on the display unit 4 in response to a user operation and a control operation of the control unit 14 will be described with reference to FIGS.

  When the user inputs characters from the numeric keypad 6a, these characters are stored in the input character string storage buffer 12f as shown in FIG. Further, as shown in FIG. 7, during the character input operation, the character string output screen 20 is displayed on the display unit 4, and the character string stored in the input character string storage buffer 12f is the character string output. It is displayed on the middle section 20a of the screen 20.

  And like the conventional portable terminal device, when the inputted character string is long, the entire character string cannot be displayed so as to fit in the middle part 20a of the character string output screen 20, so that the middle part In the part 20a, only a part of the character string is displayed, and other parts that are not displayed can be scrolled and displayed.

  As described above, when the copy and paste function is activated by the user's operation while the character string is displayed on the character string output screen 20 of the display unit 4 (step S1 in FIG. 4), the control unit 14 The character string displayed at the approximate center position of the middle stage 20a is moved to the position of the first region 20b of the middle stage 20a as shown in FIG.

  In addition, the control unit 14 displays the number of lines corresponding to each character in the character string displayed in the first region 20b in the second region 20c adjacent to the first region 20b in the horizontal direction, The number of columns corresponding to the characters is displayed in the third area 20d adjacent to each other in the vertical direction with the first area 20b.

  A guidance display is output to the lower part 20e located below the middle part 20a in the character string output screen 20. The guidance display at this time is a content that prompts the user to specify the number of lines of the first character in the range to be copied from the character string displayed in the first area 20b.

  Next, in order to designate a range to be copied from the character string, the user inputs the number of lines of the first character of this range from the numeric keypad 6a based on the number of lines displayed in the second area 20c. (Step S2 in FIG. 4), the control unit 14 stores the number of rows in the copy start point number storage buffer 12b of the storage unit 12 (Step S5 in FIG. 4).

  In addition, if an operation for designating the vertical direction with the numeric keypad 6a is performed before inputting the number of lines in step S2 in FIG. 4 (YES in step S3), the character string in the first area 20b is directed in the designated direction. It can be scrolled (step S4). When the character string in the first area 20b is scrolled up and down, the number of lines displayed in the second area 20c is scrolled simultaneously corresponding to the character string in the first area 20b. .

  Here, in step 2, it is assumed that “01” is input by the user's operation.

  Next, the control unit 14 causes the characters belonging to the number of lines specified by the user to be displayed in a color different from the characters on the other lines in the character string displayed in the first area 20b of the character string output screen 20. (Step S5).

  Here, since “01” is input in step S2, as shown in FIG. 9, the characters in the “01” line in the range surrounded by the broken line in the first area 20b are displayed in a color different from that of the other lines. It is supposed to let you. A guidance display that prompts the user to specify the number of columns of the first character in the range to be copied is output to the lower portion 20e of the character string output screen 20.

  When the user inputs the number of columns of the first character in the range to be copied from the character string (step S6 in FIG. 4), the control unit 14 stores the copy start point sequence number storage buffer 12c in the storage unit 12. The number of columns is stored (step S9).

  Similarly to the case where the character string in the first area 20b can be scrolled before the number of lines is input in the above step S2, the number of columns in the first area 20b is also input before the number of columns is input in step S6. The character string can be scrolled (NO in step S6, YES in step S7, step S8).

  Here, it is assumed that “8” is input by a user operation in step S6.

  Next, for the character string displayed in the first area 20b of the character string output screen 20, the control unit 14 returns the character displayed in a different color in step S5 to the original color and copies the starting point of the storage unit 12. Characters designated in the row number storage buffer 12b and the copy start point column number storage buffer 12c are displayed in reverse video (step S9).

  Here, since “01” and “8” are stored in the copy start point number storage buffer 12b and the copy start point number storage buffer 12c, respectively, they are displayed in the first area 20b as shown in FIG. The characters in the “01” line and the “8” column of the character string are displayed in reverse video. In addition, a guidance display that prompts the user to specify the number of lines of the last character in the range to be copied is output to the lower part 20e of the character string output screen 20.

  Next, the operation of designating the last character in the range to be copied from the character string displayed in the first area 20b is similar to designating the first character in steps S2 to S9 of FIG. The number of lines and the number of columns of the last character are input and designated (steps S10 to S16 in FIG. 5).

  Here, it is assumed that “05” is input as the number of lines of the last character in the range to be copied by the user's operation in step S10. Here, if the last character to be specified is not currently displayed in the first area 20b of the character string output screen 20, as in the case where the last character to be designated is the “05th” line, step S11 and The scroll operation in step S12 is performed to display the "05" line as shown in FIG. 11, and then the number of lines in step S10 in FIG. 5 can be input.

  Then, when the number of lines is input in step S10 of FIG. 5, the control unit 14 displays the characters belonging to this number of lines in a different color from the other lines, and in steps S4 and S6 of FIG. From the designated first character to the line immediately before the line designated in step S10 is displayed in reverse (step S13).

  Here, since “05” is input in step S10 of FIG. 5, as shown in FIG. 12, the characters on the “05” line in the range surrounded by the broken line are displayed in a different color from the other lines. At the same time, up to “04” line is highlighted.

  Then, when the number of columns is input next in step 14 of FIG. 5, the control unit 14 switches the characters displayed in different colors in step S13 to the reverse display up to the designated number of columns, Characters after the specified number of columns are normally displayed in the original color (step S17).

  Here, it is assumed that “5” is input as the number of columns of the last character in the range to be copied in step S14. Due to the operation of step S17 in FIG. 6 by the control unit 14, as shown in FIG. 13, the character string displayed in the first area of the character string output screen 20 is from the “8” column on the “01” line, The "05" row up to the "5" column is highlighted as a copy range.

  Next, in step 18 in FIG. 6, when the user performs a determination operation by pressing the center part of the cross key 6b (YES in step 18), the control unit 14 displays the designated range as shown in FIG. Is stored in the copy character string storage buffer 12a of the storage unit 12.

  When the hook-on key 6d is operated (NO in step 18 and YES in step S19), the processing operation ends without storing the character string in the specified range in the copy character string storage buffer 12a. ing.

  According to such a cellular phone 2, when an arbitrary range is specified as an operation target from the character string displayed on the display unit 4, even if the specified range is wide, it can be specified with a small number of operations. it can.

  Further, by specifying a column after designating a row as described above, an arbitrary one point in the character string is specified, and then stored in the copy character string storage buffer 12a by pressing a predetermined key. It is also possible to paste a character string to be processed.

  In the present embodiment, the character string displayed on the character string output screen 20 is displayed so as to start a new line at the eighth column of each row, but in the first area 20b of the character string output screen 20 Following the characters up to the eighth column that can be displayed, the characters in the ninth and subsequent columns may be input.

  In such a case, it is possible to instruct horizontal scrolling in step S3, step S7, step S11, and step S15 in the flowcharts of FIGS. Are displayed in the first area 20b and can be designated in step S6 and step S14.

  Further, in the present embodiment, the present invention has been described along the operation of designating a range to be copied from a character string and the operation of the mobile phone 2 using the copy and paste function. The present invention can be applied even when a function other than the copy and paste function is used, such as a cut function for cutting an arbitrary range designated from a character string.

  In this embodiment, when an arbitrary range is specified from the character string, the number of columns is input after the number of rows is input for each of the first character or the last character in the range. However, the number of rows may be input after the number of columns is input.

  In the present embodiment, the case where the present invention is applied to the mobile phone 2 has been described. However, the present invention can also be applied to other mobile terminal devices such as a PDA (Personal Digital Assistant). Needless to say.
