  Hereinafter, processing of the mobile phone according to the embodiment of the present invention will be described. Hereinafter, an example in which the maximum number of tasks that can be executed is four will be described. In other words, the maximum number of sub-screens displayed according to the task execution result is four. However, the number of sub-screens that can be displayed on the display screen is not limited to the example here, and a predetermined number may be arbitrarily determined.

  First, with reference to FIG.4 and FIG.5, the task addition process of the mobile telephone concerning this Embodiment is demonstrated. FIG. 4 is a flowchart showing task addition processing according to this embodiment. FIG. 5 is a state transition diagram of the display screen in the task addition processing of the mobile phone according to the present embodiment.

  First, the waiting screen 1, the task icon 1 and the pointer are displayed on the display screen (S200). Specifically, the CPU 20 initializes the waiting screen number information D indicating the number of the waiting waiting screen being displayed and the execution task number information T indicating the number of executing tasks to “1”. (S100). The CPU 20 executes a task 1 for displaying the waiting screen 1. The CPU 20 generates screen information indicating a display screen including the waiting screen 1, the task icon 1, and the pointer according to the execution result, and outputs the screen information to the screen control unit 30. Then, the screen control unit 30 displays a display screen on the screen display unit 40 based on the screen information output from the CPU 20 (S101, S200).

  Here, the waiting screen is a sub-screen that is displayed when the task waits and executes the screen display program. As will be described later, the child screen is not limited to one in which the display screen is divided into a plurality of areas and an image corresponding to the task execution result is displayed in each divided area. As shown in step S200, only one displayed on the display screen is included in the child screen. Further, the screen number information D and the execution task number information T are stored in, for example, a storage device such as a memory included in the mobile phone 5 or a register (not shown) included in the CPU 20.

  When the button M is pressed by the user (S102, S201), the button unit 11 outputs button pressing information indicating that the button M has been pressed to the CPU 20. Here, the button M is a button defined to function to add a task. Any button included in the button unit 11 may be defined in advance as such.

  The CPU 20 determines whether or not the execution task number information T has reached the maximum number of tasks that can be executed according to the output of the button pressing information from the button unit 11 (S103). Specifically, in the present embodiment, since the maximum number of tasks that can be executed is 4, the CPU 20 determines whether or not the execution task number information T is “3” or less.

If the maximum number of tasks that can be executed has not been reached (S103: YES), the CPU 20 adds “1” to the execution task number information T and starts executing a new task (S104). Here, only task 1 is executed, and execution task number information T is "1" and is "3" or less. Therefore, the CPU 20 adds “1” to the execution task number information T to obtain “2”. In response to the button pressing information output from the button unit 11, the execution of the task 2 that displays the waiting screen 2 is started.
When the maximum number of tasks that can be executed has been reached (S103: NO), the CPU 20 does not start executing a new task.

  The CPU 20 determines whether the waiting screen number information D has reached the maximum number of child screens (S105). Specifically, in the present embodiment, since the maximum number of child screens is four, the CPU 20 determines whether or not the waiting screen number information D is “3” or less.

  When the maximum number of child screens has not been reached (S105: YES), the CPU 20 adds “1” to the waiting screen number information D and waits according to the execution result of the task 2 that has newly started execution. The receipt screen is displayed (S106, S101). Here, the waiting screen 1 is displayed, and the waiting screen number information D is “1” and “3” or less. Therefore, the CPU 20 adds “1” to the waiting screen number information D to obtain “2”. Then, the CPU 20 generates screen information indicating a display screen including the waiting screen 2 according to the execution result of the task 2, the task icon 2 of the task 2, the task icon 1, and the pointer, and the screen control unit 30 Output to. Then, the screen control unit 30 displays a display screen on the screen display unit 40 based on the screen information output from the CPU 20.

  As a result, the waiting screen 2, the task icons 1 and 2, and the pointer are displayed on the display screen (S202). Thus, when a task 2 is newly added, the waiting screen 1 being displayed is hidden, and the waiting screen 2 of the added task 2 is displayed. Also, a task icon 2 for task 2 is added and displayed. In step S202 of FIG. 5, the task icons are task icon 1 and task icon 2 in order from the bottom. Here, the display at the time of task addition is not limited to the example here. For example, as will be described later, the display screen may be divided into a plurality of areas, and the waiting screen 1 and the waiting screen 2 may be displayed in each of the divided areas. That is, the child screen may be displayed in addition to the child screen that has been displayed.

  In step S202, the task icon 1 of the waiting screen 1 that is not displayed is displayed in white, and the task icon 2 of the waiting screen 2 that is displayed is displayed in black. In this way, when the task icon is black, it indicates that the waiting screen corresponding to the task icon is displayed, and when the task icon is white, the waiting screen corresponding to the task icon is not displayed. It shows that. Therefore, strictly speaking, the CPU 20 generates screen information indicating a display screen including the waiting screen 2, the white task icon 1, the black task icon 2, and the pointer.

  The task icon is not limited to the display exemplified here as long as the display of the task icon corresponding to the child screen is switched according to the display or non-display of the child screen. For example, the display of the task icon may be switched to a color other than those exemplified here, and the shape, size, etc. of the task icon may be switched.

  When the maximum number of child screens has been reached (S105: NO), the CPU 20 displays the first waiting screen 1 (S107). Specifically, in the state in step S202, the user further presses the button M from the state where the button M is pressed twice and two tasks 3 and 4 are added. When the user presses the button M twice more from the state in step S202 (S102, S203), the CPU 20 executes the processes of steps S102 to S105, S101 twice. As a result, the CPU 20 sets the execution task number information T to “4”, the waiting screen number information D to “4”, and starts executing the tasks 3 and 4. Then, on the display screen, the waiting screen 4 for the task 4, the white task icons 1 to 3, the black task icon 4 and the pointer are displayed (S101, S204). In addition, a task icon 3 for task 3 and a task icon 4 for task 4 are additionally displayed. In step S204 of FIG. 5, the task icons are task icon 1, task icon 2, task icon 3, and task icon 4 in order from the bottom.

  If the user presses the button M from the state in step S204 (S102, S205), the CPU 20 determines that the number of execution task information T is "4" and not less than "3" (S103: NO), so Do not start execution. In other words, since the number of tasks being executed has reached the maximum number of tasks that can be executed, the CPU 20 does not start executing a new task. Since the waiting screen number information D is “4” and not less than “3” (S105: NO), the CPU 20 waits for the first waiting screen 1, the black task icon 1, and the white task icons 2 to 2. 4, screen information indicating a display screen including a pointer is generated and output to the screen control unit 30. Then, the screen control unit 30 displays a display screen on the screen display unit 40 based on the screen information output from the CPU 20.

  As a result, the waiting screen 1, the black task icon 1, the white task icons 2 to 4, and the pointer are displayed on the display screen (S107, S206). As described above, when the task has been executed up to the maximum number of tasks that can be executed and the fourth standby screen 4 corresponding to the task 4 that is the maximum number of tasks is displayed, the task is added. Is requested, the waiting screen 1 of the task 1 that first started execution is displayed without adding a task. Thereafter, when the user further presses the button M, the same processing is performed and the second standby screen 2 is displayed. That is, when tasks are executed up to the maximum number of tasks that can be executed, the standby screens are displayed in the order of the standby screens 1 to 4 each time the button M is pressed.

  Next, with reference to FIG. 6 and FIG. 7, a process at the time of executing input for the task icon of the mobile phone according to the present embodiment will be described. FIG. 6 is a flowchart showing display switching processing of a standby screen of the mobile phone according to the present embodiment. FIG. 7 is a state transition diagram of the display screen in the display switching process of the standby screen of the mobile phone according to the present embodiment.

  First, a waiting screen 1, a black task icon 1, a white task icon 2, and a pointer are displayed on the display screen (S300, S400). Specifically, the CPU 20 is executing tasks 1 and 2, and a display screen including a waiting screen 1, a black task icon 1 for task 1, a white task icon 2 for task 2, and a pointer. Is output to the screen control unit 30. The screen control unit 30 displays a display screen on the screen display unit 40 based on the screen information output from the CPU 20.

  When an operation for moving the pointer to the task icon 2 is performed by the user, the pointer unit 12 outputs to the CPU 20 pointer operation information indicating that an operation for moving the pointer to the task icon 2 has been performed. In accordance with the pointer operation information output from the pointer unit 12, the CPU 20 generates screen information for displaying the pointer on the task icon 2 and outputs the screen information to the screen control unit 30. The screen control unit 30 displays a display screen in which the pointer is superimposed on the task icon 2 on the screen display unit 40 based on the screen information output from the CPU 20.

  When the user presses the enter button (S401), the button unit 11 outputs button press information indicating that the enter button has been pressed to the CPU 20. As described above, when the determination button is pressed in a state where the pointer is superimposed on the task icon 2, the task icon 2 is selected, and input to the task icon 2 is performed (S301).

  The CPU 20 generates screen information indicating the display screen including the waiting screens 1 and 2, the black task icons 1 and 2, and the pointer in accordance with the button pressing information output from the button unit 11 and performs screen control. To the unit 30. That is, when the task icon that has been input by the user is displayed in white, the CPU 20 further displays a waiting screen corresponding to the task icon. Further, the CPU 20 changes the task icon so that it is displayed in black. In other words, when an input is made for a task icon corresponding to a waiting screen that is not displayed, the CPU 20 switches to display the waiting screen. The screen control unit 30 displays a display screen on the screen display unit 40 based on the screen information output from the CPU 20.

  Thereby, the waiting screens 1 and 2, the black task icons 1 and 2, and the pointer are displayed on the display screen (S302, S402). Thus, when the standby screens 1 and 2 are displayed, the display screen is divided into upper and lower areas, and the standby screens 1 and 2 are displayed in the respective areas. Here, the display area is not limited to the vertical division as illustrated here. For example, it may be divided into left and right. As described above, when there is a waiting screen that is not displayed, the user can display the waiting screen by inputting the task icon corresponding to the waiting screen. Further, as shown in FIG. 7, the waiting screen 1 in step S400 is, for example, about twice as large as the waiting screens 1 and 2 in step S402.

  Here, for example, the CPU 20 stores pointer position information indicating the position of the pointer in a storage device such as a memory included in the mobile phone 5 or a register (not shown) included in the CPU 20. Then, the CPU 20 determines which task icon has pressed the determination button based on the pointer position information. That is, the CPU 20 updates the pointer position information according to the pointer operation information output from the pointer unit 12.

  When the user presses the enter button and the task icon 1 or the task icon 2 is input (S303, S403), the button unit 11 outputs to the CPU 20 button press information indicating that the enter button has been pressed. To do. The CPU 20 determines which of the task icon 1 and the task icon 2 has been input according to the button press information output from the button unit 11.

  When an input is made to the task icon 1 (S303: first), the CPU 20 displays screen information indicating a display screen including the awaiting screen 2, the white task icon 1, the black task icon 2, and a pointer. And output to the screen control unit 30. That is, when the task icon that has been input by the user is displayed in black, the CPU 20 hides the waiting screen corresponding to the task icon. Further, the CPU 20 changes the task icon so that it is displayed in white. In other words, when an input is made to the task icon corresponding to the displayed waiting screen, the CPU 20 switches so as not to display the waiting screen. The screen control unit 30 displays a display screen on the screen display unit 40 based on the screen information output from the CPU 20.

  As a result, the waiting screen 2, the white task icon 1, the black task icon 2, and the pointer are displayed on the display screen (S304, S404). As described above, when there is a waiting screen displayed, the user can hide the waiting screen by inputting the task icon corresponding to the waiting screen.

  On the other hand, when an input is performed on the task icon 2 (S303: second), the CPU 20 responds to the button pressing information output from the button unit 11 and receives the waiting screen 2, the black task icon 1, and the white color. Screen information indicating a display screen including the task icon 2 and the pointer is generated and output to the screen control unit 30. The screen control unit 30 displays a display screen on the screen display unit 40 based on the screen information output from the CPU 20. As a result, the waiting screen 1, the black task icon 1, the white task icon 2, and the pointer are displayed on the display screen.

  The CPU 20 carries, for example, standby screen display information indicating whether the standby screen is displayed or not, or task icon display information indicating whether the task icon is displayed in white or black. The data is stored in a storage device such as a memory included in the telephone 5 or a register included in the CPU 20. Then, the CPU 20 determines whether the pressed task icon is displayed or hidden based on the standby screen display information or the task icon display information, and displays the standby screen corresponding to the task icon. Determine whether to hide or hide.

For example, as exemplified in step S1102 of FIG. 14, the display is not limited to a display surrounded by a line of a predetermined format in the standby screen, and may be a display in which a color is changed.

  When an operation for moving the pointer is performed by the user (S1103), the pointer unit 12 outputs pointer operation information indicating that an operation for moving the pointer has been performed to the CPU 20. Based on the pointer operation information output from the pointer unit 12, the CPU 20 determines which area the pointer is in among the areas displaying the standby screens 1 to 4.

  When the pointer is within the area of the standby screen 3, the CPU 20 generates screen information indicating a display screen with the standby screen 3 highlighted, and outputs the screen information to the screen control unit 30. The screen control unit 30 displays a display screen on the screen display unit 40 based on the screen information output from the CPU 20. Thus, a display screen with the standby screen 3 highlighted is displayed (S1104). In other words, when the pointer crosses the boundary of the waiting screen, the CPU 20 switches the waiting screen to be highlighted.

  In the processing described above, when a pointer is displayed on the sub-screen, the sub-screen is highlighted. Thereby, the user can easily grasp the child screen on which the pointer is displayed.
