  FIG. 7 is a functional block diagram for explaining the functions and operations of the operation key group 11, the rotary dial unit 41, the processing unit 70, and the memory 110 in more detail. As illustrated in FIG. 7, the processing unit 70 includes an operation control unit (operation detection unit, rotation amount detection unit) 71, a control unit 72, an application control unit 73, and a display control unit 74.

  The memory 110 stores information to be displayed on the display 21. The memory 110 includes a storage unit 111 and a display screen information storage unit 112.

  The storage unit 111 stores display screen information for each application displayed on the display 21. Further, the information on the display screen of the application stored in the storage unit 111 is preferably information on a start screen displayed when the application is started.

  The display screen information storage unit 112 is configured by a VRAM or the like, and temporarily stores information on the display screen displayed on the display 21. Moreover, it is preferable that the information on the display screen of the application temporarily stored in the display screen information storage unit 112 is information on a start screen displayed when the application is started.

  The operation control unit 71 detects the operation of the operation key group 11 by the user and the amount of rotation in the rotary dial unit 41. The operation control unit 71 notifies the control unit 72 and the application control unit 73 of the detected operation of the operation key group 11 or the rotation amount in the rotary dial unit 41.

  When the operation control unit 71 detects a rotation amount (first rotation amount) for selecting an application, the control unit 72 refers to the storage unit 111 and acquires information on the display screen of the application. Then, the control unit 72 controls the display 21 to display the acquired information on the display screen. That is, the control unit 72 transmits the display screen information to the display control unit 74 in order to display the acquired display screen information on the display 21.

  In addition, when the operation control unit 71 detects an operation for operating the application after the operation control unit 71 detects the first rotation amount, the application display screen information stored in the storage unit 111 is as follows. It is preferable that the start screen information be displayed first when this application is started.

  As described above, the information on the display screen of the application is virtualized by setting the information on the display screen of the application as the information on the startup screen that is displayed first when the application is started. Can be easily identified by the user.

  When the application control unit 73 terminates the new application in response to the termination of the predetermined process by the processing unit 70, the control unit 72 refers to the display screen information storage unit 112 and displays information on the display screen of the application. Is controlled to be displayed on the display 21. At this time, the predetermined process by the processing unit 70 is an incoming call process, an e-mail reception process, and the like, and examples of the new application include an application having a telephone function and an application having a function related to e-mail.

  Then, when the application control unit 73 operates a new application, the information on the display screen of the application stored in the display screen information storage unit 112 is displayed on the display 21 immediately before the display screen of the new application is displayed. It is preferable that the display screen information of the application that has been displayed.

  Thus, according to the mobile phone 1 of the present embodiment, when a new application is terminated in response to the termination of the predetermined process by the processing unit 70, the display screen of the application is referred to with reference to the display screen information storage unit 112. Is displayed on the display 21 again.
