  <First Embodiment> Referring to FIG. 1, portable terminal 10 includes a key input device 22. When a call operation is performed by the key input device 22, the CPU 20 controls the radio communication circuit 14 corresponding to the CDMA system and outputs a call signal. The output call signal is transmitted from the antenna 12 and transmitted to the telephone of the other party via the mobile communication network including the base station. When the other party performs an incoming call operation, a call ready state is established.

  When a call end operation is performed by the key input device 22 after shifting to a call ready state, the CPU 20 controls the wireless communication circuit 14 to transmit a call end signal to the other party. After transmitting the call end signal, the CPU 20 ends the call process. Also when the call end signal is received from the other party first, the CPU 20 ends the call process. Also, the CPU 20 ends the call process when a call end signal is received from the mobile communication network regardless of the call partner.

  When the call signal from the other party is caught by the antenna 12 with the entire system activated, the wireless communication circuit 14 notifies the CPU 20 of the incoming call. The CPU 20 outputs the caller information described in the incoming call notification from the LCD monitor 28, and outputs a ring tone from an incoming call notification speaker (not shown). When an incoming call operation is performed by the key input device 22, a call ready state is established.

In the call ready state, the following processing is executed. The modulated audio signal (high frequency signal) sent from the other party is received by the antenna 12. The received modulated audio signal is subjected to demodulation processing and decoding processing by the wireless communication circuit 14. The received voice signal thus obtained is output from the speaker 18. The transmitted voice signal captured by the microphone 16 is subjected to encoding processing and modulation processing by the wireless communication circuit 14. The modulated audio signal generated thereby is transmitted to the other party using the antenna 12 as described above.

  FIG. 2 is an external view of the mobile terminal 10. With reference to FIG. 2, the portable terminal 10 has a case C formed in a plate shape. The antenna 12 is attached to the side surface of one end in the length direction of the case C. The key input device 22 includes a key operation group, an up direction key 22a, a down direction key 22b, a left direction key 22c, a right direction key 22d, an enter key 22e, and a switching key 22f, and each key is a push switch. Provided on the main surface of case C. The LCD monitor 28 is attached to the main surface of the case C, and the touch panel input device 24 is attached to the upper surface of the LCD monitor 28. Further, the opening OP1 leading to the speaker 18 (not shown in FIG. 2) is provided on one main surface in the length direction of the case C, and the opening OP2 leading to the microphone 16 (not shown in FIG. 2) is the other in the length direction of the case C. Is provided on the main surface. That is, the user listens to the sound output from the speaker 18 through the opening OP1, and inputs his / her own sound to the microphone 16 through the opening OP2.

  Further, when the key operation group is pressed, for example, an input operation of a telephone number or power on / off of the mobile terminal 10 is turned on. Further, when the up direction key 22a is pressed, for example, the direction of movement of the cursor that can be operated by the user can be instructed upward. By pressing the down key 22b, for example, it is possible to instruct the moving direction of the cursor that can be operated by the user downward. By pressing the left direction key 22c, for example, it is possible to instruct the moving direction of the cursor that can be operated by the user to the left. By pressing the right direction key 22d, for example, it is possible to instruct the moving direction of the cursor that can be operated by the user in the right direction. By pressing the determination key 22e, for example, a process of determining a result selected by a cursor that can be operated by the user can be performed. The switching key 22f will be described later. Here, an operation in which the user presses each key is referred to as “key input”.

  As the touch panel input device 24, for example, any one of a resistive film type, an optical type (infrared type), and a capacitive coupling type can be used. The touch panel input device 24 is a pointing device for the user to indicate an arbitrary position within the screen of the LCD monitor 28. When the touch panel input device 24 is operated by pressing, stroking, or touching the upper surface with a pen or a finger, the touch panel input device 24 outputs coordinate data of the operated operation position. That is, the user can input a stroke direction, a drawn figure, or the like into the mobile terminal 10 by using the pen or finger on the upper surface of the touch panel input device 24. Here, an operation in which the user pushes, strokes, or touches the upper surface of the touch panel input device 24 with a pen or a finger is referred to as “touch input”.

3A, 3B, 3C, 3D, 3E, and 3F can be considered as touch input patterns of the touch panel input device 24. FIG. . 3 (A) to 3 (
In the touch input shown in F), key input corresponding to the key input device 22 can be performed by stroking or drawing with a pen or finger in the direction of each arrow. For example, FIG.
The touch input shown in A) corresponds to the key input of the up direction key 22a by stroking from the bottom to the top. The touch input shown in FIG. 3B corresponds to the key input of the downward key 22b by stroking from the top to the bottom. The touch input shown in FIG. 3C corresponds to the key input of the left direction key 22c by stroking from the right to the left. The touch input shown in FIG. 3D corresponds to the key input of the right direction key 22d by stroking from left to right. The touch input shown in FIG. 3 (E) corresponds to the key input of the enter key 22e by drawing a triangle. The touch input shown in FIG. 3F corresponds to the key input of the enter key 22e by drawing a circle in the same manner as the touch input shown in FIG. As a result, the user can give the same instruction as the operation of pressing each key of the key input device 22 by pressing, stroking, or touching the upper surface of the touch panel input device 24 with a pen or a finger. it can.

  Here, the portable terminal 10 has a plurality of functions, and the plurality of functions include a music player function, an e-mail function, a multitask management function, and the like. The music player function reproduces music data stored in the flash memory 34 and outputs sound from the speaker 18. FIG. 4 shows the input correspondence of key input and touch input corresponding to the music player function processing. Note that a speaker other than the speaker 18 may be provided in the portable terminal 10 so that sound is output from a speaker other than the speaker 18.

  Referring to FIGS. 3 and 4, the “play” processing is shown in FIG. 3E when the enter key 22 e is key-input while music data playback is paused or when music data playback is paused. Touch input can be done. In the “pause” process, the enter key 22e may be input during reproduction of music data, or touch input shown in FIG. 3F may be performed during reproduction of music data. In the “music selection” process, the right direction key 22d or the left direction key 22c may be input, or touch input shown in FIG. 3D or 3C may be performed. Further, the “music selection” process performed by the key input of the right direction key 22d and the touch input shown in FIG. 3D selects the next music (music data) from the currently selected music (music data). The “music selection” process performed by the key input of the left direction key 22c and the touch input shown in FIG. 3C selects the previous music (music data) from the currently selected music (music data). To do. In the “volume adjustment” process, the up key 22a or the down key 22b may be input, or touch input shown in FIG. 3A or 3B may be performed. Further, the “volume adjustment” processing performed by the key input of the up direction key 22a and the touch input shown in FIG. 3A increases the volume with respect to the current volume, and the key input of the down direction key 22b and FIG. In the “volume adjustment” process performed by touch input shown in (), the volume is lowered with respect to the current volume. Note that the display content of the LCD monitor 28 changes so that an operation by key input or touch input is reflected. For example, if the “playback” process is performed, the character string “playing” is displayed on the LCD monitor 28.

  The multitask management function manages each of a plurality of processes processed in parallel as a plurality of tasks, and further, Active (active: function processing is possible based on a key input operation) or InActive (inactive: This is a function for switching functions) based on a key input operation. Here, the above-described switching key 22f can be switched between Active (active) and InActive (inactive) by being pressed. Then, music is played by the music player function as inactive, and e-mail is created by the e-mail creation subfunction as active.

  The electronic mail function includes an electronic mail reception subfunction, an electronic mail reply subfunction, and an electronic mail creation subfunction. To activate the e-mail creation subfunction, the e-mail creation subfunction may be activated after the e-mail function is activated. FIG. 5 shows input correspondence of key input corresponding to processing of the e-mail creation subfunction. Note that the e-mail creation subfunction does not support touch input. That is, when the e-mail creation subfunction is set to inactive, an operation by touch input cannot be performed.

Referring to FIG. 5, in the “character input” process, numeric keys 0 to 9 included in the key operation group may be key-input. In addition, the user inputs characters (character strings) such as hiragana, alphabets, and symbols by “character input” processing. In the “character conversion” process, the down key 22b may be key-input. In addition, the user converts the input hiragana to kanji by “character conversion” processing. The “character confirmation” process may be performed by inputting the enter key 22e. In addition, the user determines the kanji converted from hiragana by the “character determination” process.
It should be noted that the display content changes so that the operation by the key input is reflected on the LCD monitor 28. For example, by entering the letter as "hello" in "character input" process, the character string "Hello" is displayed on the LCD monitor 28.

  Here, with the above-described multitask management function, an operation screen or the like can be displayed on the LCD monitor 28 as in the display examples shown in FIGS. 6 (A), 6 (B), and 6 (C). is there. FIG. 6A is a display example in which the operation screen for the music player function is displayed on the LCD monitor 28, and shows a state where the music player function is set to active. FIG. 6B is a display example in which the operation screen for the e-mail creation subfunction is displayed on the LCD monitor 28, and shows a state in which the e-mail creation subfunction is set to active. FIG. 6C is a display example when the operation screen for the music player function and the operation screen for the e-mail creation subfunction are displayed at the same time. The active display area 281 includes an operation screen for the e-mail creation subfunction, The inactive display area 282 shows a state in which an operation screen for the music player function is displayed.

  By the way, when the user creates an e-mail while listening to music, when the volume of the music data being listened to is selected or the music data is selected, the music player function is selected by the switching key 22f. Must be switched from inactive to active. Furthermore, as shown in FIG. 6A, the user cannot confirm the operation screen of the e-mail creation subfunction. In other words, it is necessary to change the display content of the LCD monitor 28 for easy operation of adjusting the volume of the music data being listened to or selecting music data.

  Key input can be assigned to a plurality of keys of the key input device 22 so that the e-mail creation subfunction and the music player function can be operated simultaneously. The number of keys on device 24 cannot be increased. Also, if the key input for the e-mail creation subfunction and the music player function is assigned to a small number of keys, the operability due to the key input deteriorates.

  Therefore, in the first embodiment, a process instructed by a touch input for a function set to inactive is performed. Specifically, when the music player function plays music as a function set to inactive, and an e-mail is created using the e-mail creation subfunction as a function set to active, the e-mail creation subfunction is The process operated by key input is performed, and the music player function performs the process operated by touch input. Accordingly, the user can perform processing corresponding to the operation of the key input device 22 or the touch panel input device 24, and thus can easily perform an operation corresponding to each of the two functions processed in parallel. it can.

  For example, when an e-mail is created while listening to music, the volume of music data that is being listened to is adjusted or music data is selected by performing touch input without operating the switch key 22f. It can be carried out. In addition, since the operation result by the key input or the touch input is displayed on the LCD monitor 28, the user does not intend whether the operation of the key input device 22 or the touch panel input device 24 is an intentional operation. It is possible to determine whether the operation has been performed. That is, as shown in FIG. 6C, when displaying the operation screen of the function set to active and the function set to inactive at the same time, either the key input device 22 or the touch panel input device 24 is operated. In addition, the user can determine whether the operation of the key input device 22 or the touch panel input device 24 is an operation performed intentionally or an operation performed unintentionally.

When the operation screen of the function set to active is displayed as shown in FIG. 6A or 6B, that is, the result of processing of the function set to inactive by the user is displayed on the LCD. If it is determined that there is no need to display on the monitor 28, the result of processing of the function set to active can be confirmed using the entire display device. Further, since the input operation for the function set to active is performed while confirming the processing result of the function set to active on the LCD monitor 28, the operation is performed when touch input is performed by the touch panel input device provided on the LCD monitor 28. Sexuality gets worse. On the other hand, in the input operation for the function set to inactive, the processing result of the function set to inactive is not displayed on the LCD monitor 28. Therefore, even if touch input is performed, the operability does not deteriorate.

  The CPU 20 executes a plurality of tasks including the processing of the multitask management function shown in FIGS. 7 to 9 in parallel under the control of a multitask OS such as μITRON or Symbian. A control program corresponding to these tasks and an image displayed on the LCD monitor 28 are stored in the flash memory 34.

  The processing of the multitask management function will be described. Referring to FIGS. 7 to 9, in step S1, the music player function is activated. For example, the music player function is activated in response to a music player function activation operation. In step S3, the e-mail creation subfunction is activated. For example, the e-mail creation subfunction is activated in response to the e-mail function activation operation and the e-mail creation subfunction activation operation. In the next step S5, it is determined whether or not the music player function is set to be active. That is, here, either the already activated music player function or the e-mail creation subfunction is set to active, and the other is set to inactive.

  For example, the user makes a selection using the key input device 22 on the function selection screen that is set to active displayed on the LCD monitor 28. A function that has been activated later (here, the e-mail creation sub-function) is set to active without being set to active or inactive by the user, and is already activated (here, the music player function) May be set inactive. If YES in step S5, the music player function is set active in step S7, and the e-mail creation subfunction is set inactive. On the other hand, if NO in step S5, the e-mail creation subfunction is set active in step S9, and the music player function is set inactive.

  In the next step S11, it is determined whether or not to perform division display. That is, it is determined whether only the function set to active is displayed on the LCD monitor 28 or two activated functions are displayed on the LCD monitor 28 at the same time. For example, if the e-mail creation subfunction is set to active and the music player function is set to inactive, if YES in step S11, the e-mail creation subfunction and music player function are simultaneously displayed on the LCD monitor in step S13. 28. On the other hand, if NO in step S11, only the e-mail creation subfunction set to active is displayed on the LCD monitor 28 in step S15.

  In the next step S17, it is determined whether or not the function set to inactive corresponds to touch input. If “YES” in the step S17, that is, if the music player function that can be operated by the touch input is set to inactive, it is determined whether or not the touch input is performed in a step S19 illustrated in FIG. . For example, it is determined whether or not the touch input corresponding to FIG. If “YES” in the step S19, the function set to inactive is operated based on the touch input in a step S21. For example, the music selection function of the music player function set to inactive is performed. If YES is determined in step S11 and divided display is made, the display of the song name displayed on the LCD monitor 28 is changed as a result of the song selection process, and the sound output from the speaker 18 is changed to the selected song. Change to (music data) sound. If it is determined NO in step S11 and only the function set to active is displayed, the display on the LCD monitor 28 is not changed, and the sound output from the speaker 18 as a result of the music selection process is selected. Change to the sound of the recorded song (music data).

  If “NO” in the step S19, it is determined whether or not a key input is performed in a step S23. For example, it is determined whether or not key input has been performed by the numeric key 1 to numeric key 9 in the key operation group. If “YES” in the step S23, the function set to be active based on the key input is operated in a step S25. For example, the character input processing of the e-mail creation subfunction set to active is performed. Then, a new character string is displayed on the LCD monitor 28 as a result of the character input process. If NO in step S23, that is, if neither touch input nor key input is input, the process returns to step S19.

  In the next step S27, it is determined whether or not the switching key 22f has been operated. For example, the CPU 20 sets the function set to inactive to active, and determines whether or not an operation for setting the function set to active to inactive has been performed. That is, in the process of step S27, since the display content displayed on the LCD monitor 28 can be switched by the switching key 22f, the user selects a function (subfunction) operated by the key input device 22 or the touch panel input device 24. be able to. As a result, the function set to be active can be easily switched to the function set to be inactive, thereby improving the operability for the user.

  If “YES” in the step S27, the process returns to the step S5. On the other hand, if “NO” in the step S27, it is determined whether or not one of the functions is ended in a step S29. For example, it is determined whether or not the e-mail creation subfunction has been terminated. If NO in step S29, the process returns to step S19. On the other hand, if “YES” in the step S29, the process proceeds to a step S53 (input control process with one function) shown in FIG. A detailed description of the input control process with one function shown in FIG. 10 will be given later.

  If NO in step S17, that is, if the e-mail creation subfunction that cannot be operated by touch input is set to inactive, it is determined whether or not there is a key input in step S31 shown in FIG. judge. For example, it is determined whether or not a key input is made with the right direction key 22d or the like. If “YES” in the step S31, the function set to be active based on the key input is operated in a step S33. That is, the music selection function of the music player function set to active is performed. Then, the display of the song name displayed on the LCD monitor 28 as a result of the music selection process is changed, and the sound output from the speaker 18 is changed to the sound of the selected music (music data).

  On the other hand, if “NO” in the step S31, it is determined whether or not there is a touch panel input in a step S35. For example, it is determined whether touch input corresponding to FIGS. 3A to 3F has been performed by the touch panel input device 24. If YES in step S35, an error is displayed in step S37. That is, an image or a character string that informs the user that an operation by touch input cannot be performed is displayed on the LCD monitor 28. Thereby, the user can know the reason why the operation by the touch input cannot be performed.

  If NO in step S35, that is, if neither touch input nor key input is input, the process returns to step S31. In the next step S39, it is determined whether or not a plurality of functions are activated simultaneously. For example, it is determined whether the music player function and the e-mail creation subfunction are activated. That is, in step S39, YES is determined when the multitask management function is executed, and NO is determined when input control processing with one function is executed. When the multitask management function is executed, NO is not determined in step S39. Therefore, the case where NO is determined in step S39 will be described in the input control process (FIG. 10) with one function.

  If “YES” in the step S39, it is determined whether or not the switching key 22f is operated in a step S41 as in the process of the step S27. On the other hand, the case of NO in step S39 will be described later because the input control process with one function is executed. If “YES” in the step S41, the process returns to the step S5. On the other hand, if “NO” in the step S41, it is determined in a step S43 whether or not one of the functions has been finished as in the process of the step S29. If NO in step S29, the process returns to step S31. On the other hand, if “YES” in the step S43, the process proceeds to a step S53 (input control process with one function) illustrated in FIG. A detailed description of the input control process with one function shown in FIG. 10 will be given later.

  Next, input control processing with one function will be described. Referring to FIG. 10, in step S51, the music player function is activated. For example, the music player function is activated in response to a music player function activation operation performed by the user. Next, in step S53, it is determined whether it has been activated simultaneously with other functions. That is, it is determined whether the e-mail creation subfunction or the like is activated in addition to the music player function. If “YES” in the step S53, the process proceeds to a step S5 (see FIG. 7) of the process of the multitask management function. On the other hand, if NO in step S53, that is, if only the music player function is activated, the music player function is set to be active in step S55. In the next step S57, it is determined whether or not the function set to active corresponds to touch input. For example, it is determined whether or not the music player function set to be active supports touch input. Here, if the function set to be active is a function that does not support touch input such as an e-mail creation sub-function, it is determined NO in step S57, and therefore, in steps S31-S39, step S45, and step S47. Process.

  If “NO” in the step S57, the process proceeds to a step S31 shown in FIG. Since the processing in steps S31 to S37 has been described above, it will be omitted. Since it is determined as NO in step S39, it is determined in step S45 whether or not another function has been activated. For example, it is determined whether an activation operation of the e-mail creation subfunction has been performed. If “YES” in the step S45, the process returns to the step S53 to determine YES in order to perform the process of the multitask management function, and then the process proceeds to the step S5. If “NO” in the step S45, that is, if a starting operation of another function is not performed, it is determined whether or not an ending operation is performed in a step S47. Here, if “YES” in the step S47, that is, if an end operation is performed, the input control processing with one function is ended. On the other hand, if “NO” in the step S47, that is, if the end operation is not performed, the process returns to the step S31.

  If YES is determined in the step S57, it is determined whether or not a touch input is made in a step S59. For example, it is determined whether or not the touch input corresponding to FIG. If “YES” in the step S59, the function set to be active based on the touch input is operated in a step S61. For example, the music selection function of the music player function set to active is performed. That is, the same processing as in step S33 described above is performed. If “NO” in the step S59, it is determined whether or not a key input is performed in a step S63. For example, it is determined whether or not a key input has been performed using the left direction key 22c. If “YES” in the step S63, the function set to be active is operated based on the key input in a step S65. For example, the music selection function of the music player function set to active is performed. That is, the same processing as in step S33 described above is performed. If NO in step S63, that is, if neither touch input nor key input is input, the process returns to step S59.

In the next step S67, similarly to the process in step S45, it is determined whether or not another function activation operation has been performed. If “YES” in the step S67, the process returns to the step S53 in order to perform the processing of the multitask management function, and after determining “YES”, the process proceeds to the step S5. If “NO” in the step S67, that is, if an activation operation of another function is not performed, it is determined whether or not an ending operation is performed in a step S69 similarly to the process of the step S47. If “YES” in the step S69, that is, if an end operation is performed, the input control processing with one function is ended. On the other hand, if “NO” in the step S69, that is, if an ending operation is not performed, the process returns to the step S59.

  As can be seen from the above description, the mobile terminal 10 of the first embodiment processes a plurality of functions in parallel. The key input by the key input device 22 is effective for the function set to active, and the touch input by the touch panel input device 24 is effective for the function set to inactive. In the process of step S5, for example, the e-mail creation subfunction is set to active, and the music player function is set to inactive. Therefore, the user processes the function set to active according to the operation of the key input device 22, and processes the function set to inactive according to the operation of the touch panel input device 24. Thus, the user can easily perform operations corresponding to the e-mail creation subfunction and the music player function processed in parallel.

  In the first embodiment, the operations corresponding to the e-mail creation sub-function and music player function processed in parallel can be easily performed. The operations corresponding to the one-segment TV subfunction and the one-segment DATA subfunction included in the function may be easily performed.

  <Second Embodiment> In the second embodiment, the configuration of the portable terminal 10 of FIG. 1 used in the description of the first embodiment, the external view of the portable terminal communication terminal 10 shown in FIG. 2, and the touch panel input device shown in FIG. Since the touch input patterns of 24 are the same, those figures and the description thereof are omitted in the description of the second embodiment.

  In the second embodiment, the one-segment function is included in the plurality of functions of the mobile terminal 10. The one-segment function is a function for receiving digital terrestrial television broadcasts mainly targeted for portable devices and includes a one-segment TV sub-function and a one-segment DATA sub-function. When the one-seg function is processed, the one-seg TV sub-function and the one-seg DATA sub-function are processed in parallel. In addition, a function of switching the sub function set to active or the sub function set to inactive is provided.

  As a result, as in the first embodiment, the user can perform processing according to the operation of the key input device 22 or the touch panel input device 24, so that each of the two sub-functions processed in parallel is provided. Corresponding operations can be easily performed. In other words, the user can determine whether the operation of the key input device 22 or the touch panel input device 24 is an operation performed intentionally or an operation performed unintentionally.

  Moreover, active and inactive can be switched by the switching key 22f as in the first embodiment. Further, the digital terrestrial television broadcast signal is received by the DTV antenna 32.

Here, returning to FIG. 1, the DTV tuner 30 and the DTV antenna 32 will be described. When the channel selection operation is performed by the key input device 22, the DTV tuner 30 extracts a digital terrestrial television broadcast signal corresponding to the selected channel from the digital terrestrial television broadcast signal received by the DTV antenna 32. . Further, the DTV tuner 30 performs processing such as digital demodulation on the extracted terrestrial digital television broadcast signal to generate a demodulated signal. The demodulated signal is separated into a video broadcast demodulated signal and a data broadcast demodulated signal and output to the CPU 20. The CPU 20 performs a decoding process based on the MPEG system on the demodulated signal of the video broadcast to form a video signal. Further, the CPU 20 performs a decoding process on the demodulated signal of the data broadcast to form text data and the like.

  Next, display examples of the one-segment function will be described with reference to FIGS. 11 (A) to 11 (C). FIG. 11A shows a state in which the one-segment TV sub-function and the one-segment DATA sub-function are displayed at the same time, divided into two display areas, an active display area 281 and an inactive display area 282. In the active display area 281, the sub function set to be active is displayed, and in the display example of FIG. 11A, the one-segment TV sub function is displayed. In the inactive display area 282, the function set to inactive is displayed. In the display example of FIG. 11A, the display content of the one-segment DATA sub-function, that is, tennis that is not immediately transmitted to the user only by video broadcasting. Supplementary information (such as tournament names and player names) is displayed.

  FIG. 11B is a display example in which only the display content of the one-segment TV subfunction set to active is displayed on the LCD monitor 28. FIG. 11C is a display example in which only the display contents of the one-segment DATA sub function set to active are displayed on the LCD monitor 28. When the one-segment TV sub function is displayed on the LCD monitor 28 as shown in FIG. 11B, only the one-segment TV sub function corresponds to key input. On the other hand, when the one-segment DATA sub function is displayed on the LCD monitor 28 as shown in FIG. 11C, only the one-segment DATA sub function corresponds to key input.

  As in the first embodiment, when the display screen of the sub function set to active is displayed as shown in FIG. 11B or FIG. 11C, the LCD monitor is displayed according to the operation by touch input. Since the display content of 28 does not change, the user can determine whether the operation of the key input device 22 or the touch panel input device 24 is an operation performed intentionally or an operation performed unintentionally. Further, as shown in FIG. 11A, when the operation screens of the sub function set to active and the sub function set to inactive are displayed at the same time, the operation is performed using either the key input device 22 or the touch panel input device 24. Even when the operation is performed, the user can determine whether the operation of the key input device 22 or the touch panel input device 24 is an operation performed intentionally or an operation performed unintentionally.

  FIG. 12 is an illustrative view showing input correspondence of key input and touch input corresponding to processing of the one-segment TV sub function. Referring to FIG. 3 and FIG. 12, the “channel selection” process is performed by key-inputting any one of the number keys 1 to 9 included in the left direction key 22c, the right direction key 22d, and the key input operation group. Touch input shown in FIG. 3C or 3D may be performed. In the “volume adjustment” process, as with the music player function, the up key 22a or the down key 22b may be key-inputted, or touch input shown in FIG. 3A or FIG. Note that the display content changes so that an operation by key input or touch input is reflected on the LCD monitor 28. For example, if the “volume adjustment” process is performed, a numerical value string indicating the result of adjusting the volume is displayed on the LCD monitor 28.

  FIG. 13 is an illustrative view showing an input correspondence table of key input and touch input corresponding to the processing of the one-segment TV sub function. With reference to FIG. 3 and FIG. 13, the “up scroll” process may be performed by inputting the up direction key 22 a or performing touch input shown in FIG. In the “down scroll” process, the down key 22b may be input, or touch input shown in FIG. 3B may be performed. Note that the display content changes so that an operation by key input or touch input is reflected on the LCD monitor 28. For example, if “up scroll” processing is performed, the cursor displayed on the LCD monitor 28 moves upward.

  The CPU 20 executes in parallel a plurality of tasks including the processing of the one-segment function shown in FIGS. 14 and 15 under the control of a multitask OS such as μITRON and Symbian. A control program corresponding to these tasks and an image displayed on the LCD monitor 28 are stored in the flash memory 34.

  The processing of the one-segment function will be described. Referring to FIGS. 14 and 15, in step S101, the one-segment function is activated. For example, the one-segment function is activated in response to the activation operation of the one-segment function. In step S103, it is determined whether the one-segment DATA sub function is active. That is, it is determined whether or not the one-segment DATA sub function is operable by touch input. If the one-segment function is activated, the one-segment DATA sub function or the one-segment TV sub function may be set to be active.

  If “YES” in the step S103, that is, if the one-segment DATA sub function is active, the one-segment TV sub function is set to active and the one-segment TV sub function is set to inactive in a step S105. On the other hand, if NO in step S103, that is, if the one-segment DATA subfunction is not active, the one-segment TV subfunction is set active in step S107, and the one-segment DATA subfunction is set inactive.

  In the next step S109, it is determined whether or not to perform division display. That is, it is determined whether only the sub function set to active is displayed on the LCD monitor 28 or whether two sub functions are displayed on the LCD monitor 28 simultaneously. For example, when the 1Seg DATA sub function is set to active and the 1Seg TV sub function is set to inactive, if YES in step S109, the 1Seg DATA sub function and the 1Seg TV sub function are simultaneously displayed on the LCD monitor in step S111. 28. On the other hand, if NO in step S109, the sub-function set to active is displayed on the LCD monitor 28 in step S113, and whether or not the sub-function set to inactive in step S115 corresponds to touch input. judge. That is, it is determined whether or not the one-segment DATA sub function is set to inactive.

  If the process of step S111 ends or if NO is determined in step S115, it is determined in step S117 whether or not a touch input has been made. For example, it is determined whether or not touch input corresponding to FIG. If “YES” in the step S117, the subfunction set to inactive is operated based on the touch input in a step S119. For example, the volume adjustment (increase the volume) of the one-segment TV sub function set to inactive is performed. Then, if it is determined as YES in step S109 and the divided display is made, the numerical value string indicating the result of adjusting the volume displayed on the LCD monitor 28 as a result of the volume adjustment (volume increase) process is changed. The sound volume output from the speaker 18 is changed so as to increase. If NO is determined in step S109 and only the sub function set to be active is displayed, the display of the LCD monitor 28 is not changed, and the speaker 18 as a result of the volume adjustment (volume increase) processing is performed. Change the volume so that the volume of the output audio is increased.

If “NO” in the step S117, it is determined whether or not a key input is performed in a step S121. For example, it is determined whether or not a key input has been performed using the upward key 22a. If “YES” in the step S121, the function set to be active based on the key input is operated in a step S123. That is, the up scroll process of the one-segment DATA sub function set to active is performed. Then, the cursor displayed on the LCD monitor 28 as a result of the up scroll process is moved upward. If NO in step S121, that is, if neither touch input nor key input is input, the process returns to step S117.

  In the next step S125, it is determined whether or not the switching key 22f has been operated. For example, it is determined whether or not an operation for switching the function set to inactive to active has been performed. That is, in the process of step S125, the display content displayed on the LCD monitor 28 can be switched by the switching key 22f, so that the user can select a sub function operated by the key input device 22 or the touch panel input device 24. . As a result, as in the first embodiment, the sub-function set to active can be easily switched to the sub-function set to inactive, so that the operability for the user is enhanced.

  If “YES” in the step S125, the process returns to the step S103. On the other hand, if “NO” in the step S125, it is determined whether or not an ending operation is performed in a step S127. If “YES” in the step S127, that is, if an end operation is performed, the processing of the one-segment function is ended. On the other hand, if NO in step S127, that is, if no end operation is performed, the process returns to step S117.

  If “YES” in the step S115 described above, that is, if the one-segment DATA sub function is set to inactive, it is determined whether or not a key input has been made in a step S129 shown in FIG. For example, it is determined whether or not a key input has been performed using the upward key 22a or the like. If “YES” in the step S129, the one-segment TV sub function is operated based on the key input in a step S131. That is, the one-segment TV sub function set to active is operated. Further, for example, the volume adjustment (increase the volume) of the one-segment TV sub function set to active is performed. Then, the numerical value string representing the result of adjusting the volume displayed on the LCD monitor 28 as a result of the volume adjustment (volume increase) process is changed so that the volume of the sound output from the speaker 18 is increased. Change to

  On the other hand, if “NO” in the step S129, it is determined whether or not there is a touch input in a step S133. For example, it is determined whether touch input corresponding to FIGS. 3A to 3F has been performed by the touch panel input device 24. If YES is determined in the step S133, an error is displayed in a step S135. That is, an image or a character string that informs the user that an operation by touch input cannot be performed is displayed on the LCD monitor 28. As a result, as in the first embodiment, the user can know the reason why the operation by the touch input cannot be performed.

  If NO in step S133, that is, if neither touch input nor key input is input, the process returns to step S129. Subsequently, in step S137, similarly to step S125, it is determined whether or not the switching key 22f has been operated. If “YES” in the step S137, the process returns to the step S103. On the other hand, if “NO” in the step S137, it is determined whether or not an end operation is performed in a step S139 similarly to the step S127. Here, if “YES” in the step S139, that is, if an end operation is performed, the processing of the one-segment function is ended. On the other hand, if NO in step S139, that is, if no end operation is performed, the process returns to step S129.

As can be seen from the above description, when the mobile terminal 10 of the second embodiment performs the processing of the one seg function, the one seg TV sub function and the one seg DATA sub function are processed in parallel. The key input by the key input device 22 is effective for the sub-function set to active, and the touch input by the touch panel input device 24 is effective for the sub-function set to inactive. In the process of step S103, for example, the one-segment DATA sub function is set to active, and the one-segment TV sub function is set to inactive. Therefore, the user processes the sub function set to active according to the operation of the key input device 22, and processes the sub function set to inactive according to the operation of the touch panel input device 24. Thus, the user can easily perform operations corresponding to the one-segment DATA sub function and the one-segment TV sub function processed in parallel.

  In the present embodiment, it goes without saying that the communication method of the mobile terminal 10 is not limited to the CDMA method, but may be a PHS method, a TDMA method, or a W-CDMA method. Further, when touch input other than the touch input shown in FIGS. 3A to 3F is performed, error display may be performed in the same manner as in step S37. Further, although the music player function and the e-mail creation function have been described, it goes without saying that an Internet browser function, FM / AM radio function, digital radio function, schedule function, and the like may be used. Further, not only the mobile terminal 10 but also a mobile music player including an LCD monitor or a mobile information terminal such as a PDA.
