  The outline of the processing executed by the smartphone 1 will be described with reference to FIG. FIG. 6 is a diagram illustrating an outline of processing of the smartphone according to the embodiment.

  As illustrated in FIG. 6, when the smartphone 1 detects an incoming call, for example, when the manner mode is not set, the smartphone 1 displays a notification image P1 that notifies the user of the incoming call on the first display 2A (step S11, step S11). S12).

  On the other hand, when detecting the incoming call, for example, when the manner mode is set, the smartphone 1 displays the notification image P2 that notifies the user of the incoming call on the second display 2B (steps S11 and S13).

  In the example shown in FIG. 6, the smartphone 1 is the same as the notification image P1 that is displayed on the first display 2A when the incoming call is detected and the manner mode is not set. Although it may be an image, it is not limited to the example of FIG. For example, the smartphone 1 may make the image configuration such as the size, design, and color of the notification image P2 displayed on the second display 2B different from the notification image P1 displayed on the first display 2A.

  An example of the flow of processing executed by the smartphone 1 will be described with reference to FIG. FIG. 7 is a flowchart illustrating an example of processing executed by the smartphone according to the embodiment. The processing shown in FIG. 7 is realized by the controller 10 executing the control program 9A. If the smartphone 1 is in an operable state, the process shown in FIG. 7 is repeatedly executed even in a mode in which power feeding is partially controlled, a so-called power saving mode.

  As shown in FIG. 7, the controller 10 determines whether to notify the user (step S101).

  As a result of the determination, the controller 10 determines whether or not the manner mode is being set (step S102) when notifying the user (step S101, Yes). The manner mode may be another mode, such as the silent mode, as long as it is a notification method that does not output at least sound when notifying the user.

  If the manner mode is being set as a result of the determination (step S102, Yes), the controller 10 displays a notification image on the second display 2B (step S103), and returns to the determination in step S101.

  On the other hand, when the manner mode is not being set as a result of the determination (No at Step S102), the controller 10 displays a notification image on the first display 2A (Step S104), and returns to the determination at Step S101.

  As a result of the determination, the controller 10 determines whether the manner mode is being set (step S202) when notifying the user (step S201, Yes). The manner mode may be another mode, such as the silent mode, as long as it is a notification method that does not output at least sound when notifying the user.

  When the manner mode is being set as a result of the determination (step S202, Yes), the controller 10 displays a notification image on the second display 2B (step S203).

  The controller 10 determines whether a release operation for canceling the manner mode setting has been performed (step S204).

  As a result of the determination, when the canceling operation for canceling the manner mode setting is performed (Yes in step S204), the controller 10 sets the second display 2B in a transparent state and displays a notification image on the first display 2A ( In step S205, the process returns to the determination in step S201.

  As a result of the determination, when the release operation for canceling the manner mode setting is not performed (No at Step S204), the controller 10 returns to the determination at Step S201.

  In step S202, if the result of determination is that the manner mode is not being set (step S202, No), the controller 10 displays a notification image on the first display 2A (step S205), and returns to the determination in step S201. .

  In step S201, if the controller 10 does not execute notification to the user as a result of the determination (No in step S201), the controller 10 repeatedly executes the determination in step S201.

  According to the process shown in FIG. 8, the smartphone 1 uses the second display 2B to execute display related to the notification to the user, and then uses the first display 2A if the manner mode setting is canceled. And display related to the notification to the user. Therefore, it is possible to consider the user operation corresponding to the notification while considering the surrounding environment.
