FIG. 6 is a diagram illustrating an example of control in the case where the suspended function is resumed. FIG. 7 is a diagram illustrating another example of resuming a suspended function. FIG. 8 is a diagram illustrating an example of control when the function being executed is terminated.

  In the following description, it is assumed that the mobile phone terminal 1 is in the second form and the touch panel 3 is exposed to the outside. The touch panel 2 is normally used as a display unit on which an object for activating a function of the mobile phone terminal 1 is displayed, and the touch panel 2 normally displays a screen provided by the activated function. It shall be used as a display unit.

  In step S <b> 11 shown in FIG. 3, a standby screen on which the icon 21, the icon 22, and the icon 23 are arranged is displayed on the touch panel 2. The touch panel 3 displays a standby screen on which no icons are arranged. The icon 21 is an object used to activate the WEB browsing function. The icon 22 is an object used to activate the electronic mail function. The icon 23 is an object used to activate the call function. In this embodiment, an icon 21 or the like made of a pictograph is displayed as an object for activating a function of the mobile phone terminal 1, but a menu item, a button, or the like is displayed as an object for activating the function. It may be displayed.

  The standby screen is a screen waiting for an incoming / outgoing call or a screen waiting for an application program to start. In other words, the standby screen is a screen before the screen is changed to various function screens provided by the mobile phone terminal 1. The standby screen may be called an initial screen, a desktop screen, a home screen, or wallpaper, for example. In the example shown in FIG. 3, the plain screen is displayed as the standby screen, but image data or animation data may be displayed as the standby screen. In addition, as a part of the standby screen, a dynamically changing part such as a calendar or a clock may be included.

  Here, it is assumed that the user performs a tap operation on the icon 22. The tap operation is an operation of releasing a finger immediately after touching the touch panel so as to tap an icon or the like.

  As described above, when the tap operation is performed on the object in a state where the function screen is not displayed, the mobile phone terminal 1 activates the function corresponding to the tapped object, and the screen corresponding to the function. Is displayed on the touch panel 3. In the example illustrated in FIG. 3, the cellular phone terminal 1 activates an e-mail function corresponding to the icon 22 and displays a mail creation screen 31 provided by the e-mail function on the touch panel 3 in step S <b> 12.

  In step S21 shown in FIG. 4A, as in step S12 of FIG. 3, a standby screen on which the icons 21, 22 and 23 are arranged is displayed on the touch panel 2, and mail is displayed on the touch panel 3. A creation screen 31 is displayed. That is, in step S21, only the electronic mail function corresponding to the icon 22 is activated. Here, it is assumed that the user performs a tap operation on the icon 21.

  As described above, when a tap operation is performed on an object during execution of some function, the mobile phone terminal 1 interrupts the function being executed, and the symbol corresponding to the interrupted function is tapped. Display in or near the object display area. In addition, the mobile phone terminal 1 activates a function corresponding to the tapped object, and displays a screen corresponding to the function on the touch panel 3.

  The symbol here is displayed to indicate that there is another function interrupted to activate the function being executed. The symbol may be a simple figure such as a simple circle or rectangle, for example, but a character indicating the name of another function that has been interrupted or another interrupted function such as the example in FIG. It is preferable that the icon corresponding to the function is reduced. If a symbol indicating a name of another interrupted function or an icon corresponding to the interrupted function is reduced as a symbol, the user can easily identify the interrupted function.

  Note that displaying a symbol in or near the object display area includes displaying the symbol so as to partially overlap the object display area. Further, in the following description, displaying a symbol in or near the display area of the object may be expressed as adding a symbol to the object.

  In the example illustrated in FIG. 4A, the cellular phone terminal 1 interrupts the electronic mail function and adds a symbol 22a corresponding to the electronic mail function to the icon 21 in step S22. Then, the cellular phone terminal 1 activates the WEB browsing function corresponding to the icon 21 and displays the browser screen 32 provided by the WEB browsing function on the touch panel 3.

  As shown in this example, by adding a symbol corresponding to the suspended function to the icon corresponding to the function being executed, the user simply looks at the symbol added to the icon, and which function is suspended. You can see if there is. Also, the user can grasp which function is currently being executed simply by looking at the icon. Moreover, such an effect is realized without lowering the utilization efficiency of the touch panel 2 or the like by using an existing icon display area. In portable electronic devices, since the area of the display unit is often relatively small, it is very important not to reduce the utilization efficiency of the display unit.

  As shown in FIG. 4B, an icon to which a symbol corresponding to the suspended function is added may be displayed in an enlarged manner. By controlling in this way, it becomes easier for the user to grasp which function is being interrupted and to identify the added symbol. Further, as shown in FIG. 4-3, icons and symbols may be displayed in an integrated manner.

  In step S31 shown in FIG. 5, the standby screen on which the icon 21, the icon 22, and the icon 23 are arranged is displayed on the touch panel 2, and the browser screen 32 is displayed on the touch panel 3, as in step S <b> 22 of FIG. 4. Is displayed. Further, a symbol 22a corresponding to the e-mail function is added to the icon 21. That is, in step S31, the WEB browsing function is being executed and the electronic mail function is being interrupted. Here, it is assumed that the user performs a tap operation on the icon 23.

  As described above, when a tap operation is performed on an object during execution of some function, the mobile phone terminal 1 interrupts the function being executed, and the symbol corresponding to the interrupted function is tapped. Append to object. At this time, the cellular phone terminal 1 also adds a symbol corresponding to the suspended function to the tapped object. In addition, the mobile phone terminal 1 activates a function corresponding to the tapped object, and displays a screen corresponding to the function on the touch panel 3.

  In the example shown in FIG. 5, the cellular phone terminal 1 interrupts the WEB browsing function and adds a symbol 21a corresponding to the WEB browsing function and a symbol 22a corresponding to the e-mail function to the icon 23 in step S32. . Then, the cellular phone terminal 1 activates a call function corresponding to the icon 23 and displays a call screen 33 provided by the call function on the touch panel 3.

  Here, when there are a plurality of suspended functions, the symbols corresponding to the suspended functions are arranged in order from the shortest elapsed time since the interruption. In this way, by arranging the symbols in order of short elapsed time since the interruption, the user can grasp in what order the functions are interrupted. In addition, as will be described later, since the function with the shortest elapsed time since the interruption is the target of resumption, the user can determine which function is resumed when an operation for resuming the suspended function is performed. I can grasp it.

  When there are many interrupted functions, only a predetermined number of symbols may be added to an object such as an icon in order to avoid complicated display. In this case, a character such as “...” May be added to indicate that there is a symbol that is not added.

  In step S41 shown in FIG. 6, as in step S32 of FIG. 5, a standby screen on which the icons 21, 22 and 23 are arranged is displayed on the touch panel 2, and the call screen 33 is displayed on the touch panel 3. Is displayed. Further, a symbol 21a corresponding to the WEB browsing function and a symbol 22a corresponding to the electronic mail function are added to the icon 23. That is, in step S41, the call function is being executed, and the WEB browsing function and the e-mail function are being interrupted. Here, it is assumed that the user performs a tap operation on the icon 23.

  As described above, when a tap operation is performed on an object to which a symbol indicating that there is a suspended function is added, the mobile phone terminal 1 interrupts the function being executed, The function with the shortest elapsed time after being interrupted at is resumed. At this time, the cellular phone terminal 1 adds a symbol corresponding to the suspended function to the object corresponding to the resumed function. In addition, the mobile phone terminal 1 displays a screen corresponding to the resumed function on the touch panel 3.

  In the example illustrated in FIG. 6, the mobile phone terminal 1 interrupts the call function, resumes the WEB browsing function having the shortest elapsed time since being interrupted, and performs the browser screen 32 provided by the WEB browsing function in step S42. Is displayed on the touch panel 3. Further, the cellular phone terminal 1 adds a symbol 23 a corresponding to the interrupted call function and a symbol 22 a corresponding to the interrupted electronic mail function to the icon 21.

  In step S51 shown in FIG. 7, a standby screen on which the icon 21, the icon 22, and the icon 23 are arranged is displayed on the touch panel 2, and the call screen 33 is displayed on the touch panel 3, as in step S32 of FIG. Is displayed. Further, a symbol 21a corresponding to the WEB browsing function and a symbol 22a corresponding to the electronic mail function are added to the icon 23. That is, in step S51, the call function is being executed, and the WEB browsing function and the e-mail function are being interrupted. Here, it is assumed that the user performs a pinch operation on the icon 23. The pinch operation refers to an operation in which a plurality of fingers are brought into contact with the touch panel and then the distance between the contact positions of the fingers is changed by moving the fingers while maintaining contact with the touch panel.

  Thus, when a pinch operation is performed on an object to which a symbol indicating that there is an interrupted function is added, the mobile phone terminal 1 interrupts the function being executed, The function with the shortest elapsed time after being interrupted at is resumed. At this time, the cellular phone terminal 1 adds a symbol corresponding to the suspended function to the object corresponding to the resumed function. Further, the mobile phone terminal 1 displays a screen corresponding to the resumed function on the touch panel 2 instead of the touch panel 3.

  In the example illustrated in FIG. 7, the mobile phone terminal 1 interrupts the call function, resumes the WEB browsing function having the shortest elapsed time since being interrupted, and performs the browser screen 32 provided by the WEB browsing function in step S52. Is displayed on the touch panel 2. Further, the cellular phone terminal 1 adds a symbol 23 a corresponding to the interrupted call function and a symbol 22 a corresponding to the interrupted electronic mail function to the icon 21.

  As is clear from the examples shown in FIGS. 6 and 7, the mobile phone terminal 1 allows the user to specify on which display unit the screen provided by the resumed function is displayed by a simple operation. It is configured to be able to. 6 and 7, the function suspended by the operation on the object to which the symbol is added is resumed. However, when the tap operation is performed on the icon corresponding to the suspended function. In addition, the function corresponding to the icon may be resumed.

  Here, the suspended function is resumed when a tap operation or pinch operation is performed on an object to which a symbol indicating that there is a suspended function is added. The suspended function may be resumed by another operation such as a tap operation. For example, when an operation for rotating an object to which a symbol indicating that there is a suspended function is performed, the suspended function may be resumed. In this case, depending on the amount of rotation of the object, the suspended functions may be resumed one by one in the order from the shortest elapsed time since the interruption.

  Further, when an operation of dragging an object to which a symbol indicating that there is a suspended function is performed, the suspended function may be resumed. In this case, if the finger is released when the object is dragged from the touch panel 2 to the touch panel 3, the screen provided by the resumed function is displayed while the screen provided by the function being executed is displayed on the touch panel 3. It may be displayed on the touch panel 2. If the finger is released when the object is dragged from the touch panel 3 to the touch panel 2, the screen provided by the function being executed is displayed on the touch panel 2, and the screen provided by the resumed function is displayed on the touch panel 3. It may be displayed. The relationship between the drag direction and the display position of the screen may be reversed.

  In step S61 shown in FIG. 8, the standby screen on which the icons 21, 22 and 23 are arranged is displayed on the touch panel 2 and the call screen 33 is displayed on the touch panel 3 as in step S32 of FIG. Is displayed. Further, a symbol 21a corresponding to the WEB browsing function and a symbol 22a corresponding to the electronic mail function are added to the icon 23. That is, in step S61, the call function is being executed, and the WEB browsing function and the e-mail function are being interrupted. Here, it is assumed that the user has performed a predetermined operation for terminating the call function.

  As described above, when a predetermined operation for ending the function being executed is performed, the mobile phone terminal 1 ends the function being executed, and the elapsed time since being interrupted among the interrupted functions is the longest. Resume short functions. At this time, if there is another suspended function, the cellular phone terminal 1 adds a symbol corresponding to the suspended function to the object corresponding to the resumed function. In addition, the mobile phone terminal 1 displays a screen corresponding to the resumed function on the touch panel 3.

  In the example shown in FIG. 8, the mobile phone terminal 1 terminates the call function, resumes the WEB browsing function having the shortest elapsed time since being interrupted, and resumes the browser screen 32 provided by the WEB browsing function in step S62. Is displayed on the touch panel 3. In addition, the cellular phone terminal 1 adds a symbol 22 a corresponding to the suspended email function to the icon 21.

  Next, a functional configuration of the mobile phone terminal 1 will be described with reference to FIG. FIG. 9 is a block diagram showing a functional configuration of the mobile phone terminal 1. As shown in FIG. 9, the mobile phone terminal 1 includes a touch panel 2, a touch panel 3, a posture detection unit 4, a power supply 5, a communication unit 6, a speaker 7, a microphone 8, a storage unit 9, and main control. Section 10 and a RAM (Random Access Memory) 11. In addition, except for the touch panel 2 being provided in the first casing 1A and the touch panel 3 being provided in the second casing 1B, each part is the first casing 1A and the second casing 1B. Either may be provided.

  The touch panel 2 includes a display unit 2B and a touch sensor 2A superimposed on the display unit 2B. The touch panel 3 includes a display unit 3B and a touch sensor 3A superimposed on the display unit 3B. The touch sensor 2 </ b> A and the touch sensor 3 </ b> A detect various operations performed on the surface using a finger together with the position where the operation is performed. The operations detected by the touch sensor 2A and the touch sensor 3A include a tap operation, a pinch operation, and the like. The display unit 2B and the display unit 3B include, for example, a liquid crystal display (LCD), an organic EL (Organic Electro-Luminescence) panel, and the like, and display characters, figures, images, and the like.

  The posture detection unit 4 detects whether the mobile phone terminal 1 is in the first form or the second form. The posture detection unit 4 detects the posture of the mobile phone terminal 1 using, for example, a mechanical switch provided on a surface where the first housing 1A and the second housing 1B face each other.

  The power source 5 supplies power obtained from a storage battery or an external power source to each functional unit of the mobile phone terminal 1 including the main control unit 10. The communication unit 6 establishes a radio signal line by a CDMA system or the like with a base station via a channel assigned by the base station, and performs telephone communication and information communication with the base station. The speaker 7 outputs the other party's voice, ringtone, and the like in telephone communication. The microphone 8 converts the voice of the user or the like into an electrical signal.

  The storage unit 9 is, for example, a nonvolatile memory or a magnetic storage device, and stores programs and data used for processing in the main control unit 10. Specifically, the storage unit 9 includes a mail program 9A for realizing an e-mail function, a browser program 9B for realizing a WEB browsing function, a call program 9C for realizing a call function, A screen control program 9D for realizing such screen control and execution status data 9E storing information related to the execution status of functions are stored. In addition, the storage unit 9 stores other programs and data such as an operating system program for realizing basic functions of the mobile phone terminal 1 and address book data in which names, telephone numbers, mail addresses, etc. are registered. Is done.

  Here, the execution status data 9E will be described with reference to the drawings. FIG. 10 is a diagram illustrating an example of the execution status data 9E. As shown in FIG. 10, the execution status data 9E has items such as a hierarchy number and a program name, and data is stored for each activated function. The execution status data 9E is provided for each display unit, and the execution status data 9E shown in FIG. 10 is the execution status data 9E corresponding to the touch panel 3 at the time of step S32 shown in FIG.

  In the item of the hierarchy number, a value indicating the function execution order is stored. Specifically, when a certain function is being executed, “0” is stored in the item of the layer number of the data corresponding to the function. In addition, when a certain function is suspended, the value of “1” or more assigned to the item of the hierarchical number of the data corresponding to the function by increasing the value one by one in the shortest elapsed time since the interruption. Is stored. The name of a program for realizing the function is stored in the program name item.

  In the first line data of the execution status data 9E shown in FIG. 10, “0” is stored in the hierarchy number item, and “call program” is stored in the program name item. This data indicates that a call function realized by the call program 9C is being executed. Further, in the second row data of the execution status data 9E shown in FIG. 10, “1” is stored in the item of the hierarchy number, and “browser program” is stored in the item of the program name. This data indicates that the WEB browsing function realized by the browser program 9B is being suspended, and the elapsed time since the interruption is the shortest. Further, in the third row data of the execution status data 9E shown in FIG. 10, “2” is stored in the hierarchy number item, and “mail program” is stored in the program name item. This data indicates that the electronic mail function realized by the mail program 9A is suspended, and the elapsed time since the interruption is the second shortest.

  The execution status data 9E is updated by the main control unit 10 every time a function is activated, interrupted, resumed, terminated, or the like.

  The main control unit 10 is, for example, a CPU (Central Processing Unit), and comprehensively controls the operation of the mobile phone terminal 1. Specifically, the main control unit 10 executes the program stored in the storage unit 9 while referring to the data stored in the storage unit 9 as necessary, so that the touch panel 2, the communication unit 6, etc. Various processes are executed by controlling. The main control unit 10 expands the program stored in the storage unit 9 and the data acquired / generated / processed by executing the process to the RAM 11 that provides a temporary storage area as necessary. The program executed by the main control unit 10 and the data to be referred to may be downloaded from the server device by wireless communication by the communication unit 6.

  For example, the main control unit 10 realizes an electronic mail function by executing the mail program 9A. Further, the main control unit 10 executes the screen control program 9D to realize a function of changing the display mode of an object such as an icon in accordance with the execution or interruption of the function as described above.

  Next, a processing procedure executed by the main control unit 10 based on the screen control program 9D will be described with reference to FIG. Note that the processing procedure shown in FIG. 11 is executed each time the touch panel 2 detects contact with an object such as an icon corresponding to an executable function when the mobile phone terminal 1 is in the second form.

  FIG. 11 is a flowchart showing the operation of the main control unit 10 when contact with an icon corresponding to an executable function is detected. As shown in FIG. 11, when contact with the icon is detected by the touch panel 2 as step S101, the main control unit 10 determines whether a symbol is added to the icon with contact detected as step S102. The fact that a symbol is added to an icon means that, for example, data of a function corresponding to the icon is set to “0” in the item of the hierarchy number and stored in the execution status data 9E, and the execution status data 9E Can be determined from the fact that data of other functions are stored in

  When a symbol is not added to the icon for which contact is detected (No at Step S102), the main control unit 10 determines whether the contact is due to a tap operation as Step S103. Here, when the contact is not due to a tap operation (step S103, No), the main control unit 10 does not perform any particular processing.

  When the contact is due to a tap operation (step S103, Yes), the main control unit 10 determines whether there is a function being executed as step S104. Whether there is a function being executed is determined from, for example, whether data is stored in the execution status data 9E. When there is no function being executed (No at Step S104), the main control unit 10 activates a function corresponding to the tapped icon and displays a screen provided by the function on the touch panel 3 at Step S108.

  When there is a function being executed (step S104, Yes), the main control unit 10 erases the symbol added to the icon of the function being executed as step S105, and interrupts the function being executed as step S106. Let In step S107, the main control unit 10 adds the suspended function symbol to the tapped icon. Thereafter, in step S108, the main control unit 10 activates a function corresponding to the tapped icon and causes the touch panel 3 to display a screen provided by the function.

  On the other hand, when a symbol is added to the icon for which contact has been detected (step S102, Yes), the main control unit 10 determines whether the contact is due to a tap operation as step S109. When the contact is due to a tap operation (step S109, Yes), the main control unit 10 sets the function whose execution was interrupted last as a target to be resumed as step S110. Here, the function whose execution was interrupted last time can be specified by searching the execution status data 9E for data in which “1” is set in the item of the hierarchy number, for example.

  Subsequently, the main control unit 10 deletes the symbol added to the icon of the function being executed at step S111, and interrupts the function being executed at step S112. In step S113, the main control unit 10 adds the suspended function symbol to the icon of the function to be resumed. At this time, the symbols are arranged in the order from the shortest elapsed time since the interruption based on the value of the item of the hierarchical number of the execution status data 9E. Thereafter, in step S114, the main control unit 10 resumes the function to be resumed and causes the touch panel 3 to display a screen provided by the function.

  When the contact is not due to a tap operation (No at Step S109), the main control unit 10 determines whether the contact is due to a pinch operation as Step S115. When the contact is not due to a pinch operation (No at Step S115), the main control unit 10 does not perform any particular processing.

  If the contact is due to a pinch operation (step S115, Yes), the main control unit 10 sets the function whose execution was last interrupted as a restart target in step S116. Subsequently, in step S117, the main control unit 10 deletes the symbol of the function to be resumed from the icon of the function being executed. In step S118, the main control unit 10 resumes the function to be resumed, and displays the screen provided by the function on the touch panel 2 instead of the touch panel 3.

  As described above, in this embodiment, since the symbol corresponding to the interrupted function is added to the icon corresponding to the function being executed, the user can easily determine which function is being interrupted. Can grasp.
