  FIG. 1 is an external perspective view of an electronic device 1 according to an embodiment of the present invention when viewed from the front. FIG. 2 is an external perspective view of the electronic apparatus 1 according to an embodiment of the present invention when viewed from the back. The electronic device 1 is, for example, a smartphone. The electronic device 1 includes a front face 1A, a back face 1B, and a side face 1C. The front face 1 </ b> A is the front of the electronic device 1, and the back face 1 </ b> B is the back of the electronic device 1. The side face 1C is a side surface that connects the front face 1A and the back face 1B over the entire circumference.

  Next, functions of the electronic device 1 will be described with reference to FIG.

  FIG. 3 is a functional block diagram showing a schematic configuration of the electronic apparatus 1 according to an embodiment of the present invention. The electronic device 1 includes a display 2, a key 3, cameras 4A and 4B, a receiver 5, a lamp 6, a proximity sensor 7, a light 8, a speaker 9, a microphone 10, a vibrator 11, and a connector 12. And a battery 13, a first wireless unit 14, a second wireless unit 15, a third wireless unit 16, a storage 20 as a storage unit, and a controller 21 as a control unit.

  The display 2 includes a display panel 2A and has a display function. The display panel 2A is configured by, for example, an LCD (Liquid Crystal Display), an organic EL (Electro Luminescence), an inorganic EL, or the like. The display panel 2A displays characters, images, symbols, graphics, or the like, for example.

  The display 2 includes a touch sensor 2B having an input function. The touch sensor 2B is formed in a transparent sheet shape and is disposed on the display panel 2A. The user visually recognizes the display panel 2A through the touch sensor 2B. The touch sensor 2 </ b> B detects, for example, a position where a user's finger, a stylus pen, or the like contacts the display 2 as an input to the user's display 2.

  Key 3 has an input function as a hard key. The key 3 is operated by the user. The controller 21 detects a user operation on the key 3 as an input in cooperation with the key 3. User operations on the keys are, for example, click, double click, push, long push, and multi-push. The key 3 includes operation keys 3A to 3C, a volume key 3D, a power key 3E, and a security buzzer key 3F.

  The operation keys 3A to 3C are keys for displaying a desired screen on the display 2 when the electronic device 1 is in a power-on state. For example, push button type keys are employed as the operation keys 3A to 3C as hard keys. The operation keys 3A to 3C may be soft keys. In this case, for example, touch sensor type keys are employed as the operation keys 3A to 3C. When the operation keys 3A to 3C are soft keys, the input function of the touch sensor 2B may detect a user operation on the operation keys 3A to 3C. In this case, the operation keys 3A to 3C may be arranged in the display 2 (touch sensor 2B).

  The operation key 3A is, for example, a back key. The user presses the operation key 3A to return the current screen displayed on the display 2 to the previous screen. The operation key 3B is, for example, a home key. When the user wants to display the home screen on the display 2, the user presses the operation key 3B. The operation key 3C is, for example, a menu key. When the user wants to display the menu screen on the display 2, the user presses the operation key 3C.

  The volume key 3D is a key for adjusting the volume of sound output from the receiver 5 and the speaker 9. The volume key 3D includes, for example, two keys, an up key and a down key. For example, push-button keys are employed as the up key and the down key as hard keys. When the user wants to increase the volume of the sound output from the receiver 5 or the speaker 9, the user presses the up key marked with “+”. Further, when the user wants to lower the volume of the sound output from the receiver 5 or the speaker 9, the user presses the down key marked with “−”.

  The power key 3E is a key for starting up the electronic apparatus 1. As the power key 3E as a hard key, for example, a push button type key is adopted. The user presses the power key 3E to activate the electronic device 1 whose power is off. The user can also press the power key 3E for a long time (for example, 1 second or longer) to shift the electronic device 1 in the normal mode to the pseudo power-off mode. Further, when the user wants to cancel the pseudo power-off mode of the electronic device 1, the user presses the power key 3E for a long time (for example, 1 second or longer). The normal mode and the pseudo power-off mode will be described later.

  Even when the electronic device 1 is in the pseudo power-off mode, the electronic device 1 may be set in advance so that the power of the electronic device 1 can be turned off by the power key 3E. That is, even when the electronic device 1 is in the pseudo power-off mode, the input function of the power key 3E may be made valid as a key for turning off the power of the electronic device 1. For example, the electronic device 1 may be set to shift to the power-off mode when the user presses the power key 3E for a longer time (for example, 3 seconds or more) than when the pseudo power-off mode is set.

  The security buzzer key 3F is a key for causing the electronic device 1 to execute a security buzzer function. For example, a push button type key is adopted as the crime prevention buzzer key 3F as a hard key. For example, when the user encounters a suspicious person, the user presses the security buzzer key 3F.

  Note that the input function of the security buzzer key 3F is enabled not only when the electronic device 1 is in the normal mode but also when the electronic device 1 is in the pseudo power-off mode. This is because the electronic device 1 can execute the security buzzer function not only in the normal mode but also in the pseudo power-off mode. The security buzzer function will be described later.

  The cameras 4A and 4B have a shooting function. The camera 4A is a so-called in-camera and photographs an object facing the front face 1A. The camera 4B is a so-called out-camera and photographs an object facing the back face 1B.

  The receiver 5 converts the sound signal transmitted from the controller 21 into sound and outputs the sound. The receiver 5 outputs the voice of the other party during the call.

  The lamp 6 has a notification function. The lamp 6 includes, for example, an LED (Light Emitting Diode). For example, the lamp 6 is turned on when the battery 13 is being charged to notify the user that the battery 13 is being charged. Further, for example, the lamp 6 is turned on when mail is received, and notifies the user that mail has been received. Further, for example, the lamp 6 is turned on when an incoming call is received to notify the user that the incoming call has been received.

  The proximity sensor 7 has a detection function. The proximity sensor 7 detects the presence of a nearby object without contact. For example, the user brings the display 2 close to the face when making a call using the electronic device 1. At this time, the proximity sensor 7 detects the user's face as a nearby object. When the proximity sensor 7 detects the user's face as a nearby object, the controller 21 turns off the display function of the display 2.

  The light 8 has a light emitting function. The light 8 includes, for example, an LED. For example, the light 8 emits light when the camera 4B captures an object. For example, the light 8 can emit light as simple illumination.

  The speaker 9 has a notification function. For example, the speaker 9 outputs a predetermined ring tone when there is an incoming call to notify the user that there is an incoming call. Further, for example, the speaker 9 outputs a predetermined alarm sound at a preset time to notify the user that it is the predetermined time.

  The microphone 10 converts the voice of the user who is talking and nearby sounds into audio signals and transmits them to the controller 21.

  The vibrator 11 has a notification function. The vibrator 11 includes a vibrator such as a piezoelectric element. For example, the vibrator 11 vibrates when receiving a mail and notifies the user that the mail has been received. Further, for example, the vibrator 11 vibrates during an incoming call and notifies the user that the incoming call is being received.

  The connector 12 is a terminal to which another device is connected. The connector 12 is, for example, a USB (Universal Serial Bus) terminal. When the USB cable of the charger is connected to the connector 12, the battery 13 is charged. The battery 13 supplies power to the components in the electronic device 1.

  The first wireless unit 14 has a communication function. The first wireless unit 14 communicates with other electronic devices and a server connected to the Internet via the base station. The first wireless unit 14 performs communication based on a communication standard such as LTE (Long Term Evolution).

  The second wireless unit 15 has a reception function. The second wireless unit 15 receives radio waves from a GPS (Global Positioning System) satellite. When the second wireless unit 15 receives radio waves from GPS satellites, the controller 21 acquires position information of the electronic device 1.

  The third wireless unit 16 has a communication function. The third wireless unit 16 communicates with other devices by short-range wireless communication, for example. The third wireless unit 16 performs communication based on, for example, Bluetooth (registered trademark). In addition, the third wireless unit 16 can connect to a WiFi (Wireless Fidelity) spot.

  The storage 20 stores programs and data as a storage unit. The storage 20 is also used as a storage unit that temporarily stores the processing result of the controller 21. The storage 20 may be composed of any storage device such as a semiconductor storage device and a magnetic storage device. Further, the storage 20 may be composed of a plurality of types of storage devices. The storage 20 may be configured by a combination of a portable storage medium such as a memory card and a storage medium reading device.

  The programs stored in the storage 20 include an application executed in the foreground or background and a control program that supports the operation of the application. For example, the application displays a predetermined image on the display 2 and causes the controller 21 to execute a process corresponding to a user operation detected via the touch sensor 2B. The control program is an OS (Operating System). The application and the control program may be installed in the storage 20 via wireless communication by the first wireless unit 14 or the like or a storage medium.

  The controller 21 controls and manages the entire electronic device 1 as a control unit. The controller 21 is configured by any suitable processor such as a general-purpose CPU (central processing unit) that reads software for executing processing of each function. Or the controller 21 may be comprised by the processor for exclusive use specialized in the process of each function, for example. A program executed by the controller 21 is stored in the storage 20.

  In this embodiment, the controller 21 will perform a security buzzer function, if the user operation with respect to the security buzzer key 3F is detected. For example, the controller 21 causes the speaker 9 to output a buzzer sound or causes the camera 5B to photograph a suspicious person. At this time, the buzzer sound output from the speaker 9 may have a volume exceeding the maximum value that can be set by the user operating the volume key 3D. Further, the controller 21 may make an emergency notification using a mail function or the like to a partner security company or an emergency contact address registered in advance. At this time, the controller 21 may notify the location information of the user acquired by the second wireless unit 15 together with the emergency notification to the security company or the emergency contact information registered in advance. For example, when an emergency notification is received, the security company determines the position of the user from the position information of the electronic device 1 and prompts a security guard patroling the vicinity of the determined position to the scene, or contacts the police, etc. To do.

  The security buzzer function can be executed not only when the electronic device 1 is in the normal mode but also when the electronic device 1 is in the pseudo power-off mode. When executing the security buzzer function when the electronic device 1 is in the pseudo power-off mode, the controller 21 shifts the electronic device 1 from the pseudo power-off mode to the normal mode.

  In the present embodiment, the controller 21 executes a security buzzer function as a function related to crime prevention, but is not limited to this. Moreover, in this embodiment, although the function which concerns on a crime, ie, a security buzzer function, shall be performed by operation with respect to the security buzzer key 3F as a trigger, it is not limited to this. For example, the security buzzer function may be executed when the user pulls the strap provided in the electronic device 1 with a predetermined force or more.

  The controller 21 executes each function according to the mode of the electronic device 1. The modes of the electronic device 1 include, for example, a normal mode, a sleep mode, a power off mode, and a pseudo power off mode. Hereinafter, these modes will be described.

<Normal mode>
The normal mode is a mode in which the power source of the electronic device 1 is on and almost all the functions of the electronic device 1 are executable. The functions of the electronic device 1 include, for example, main functions and additional functions. The main functions are, for example, an incoming call function, an outgoing call function, an e-mail reception function, an e-mail transmission function, a security buzzer function, an answering machine function, and the like. Additional functions include, for example, the display function of the display 2, the notification function of the speaker 9, the notification function of the vibrator 11, the notification function of the lamp 6, the input function of the touch sensor 2B, the light emission function of the light 8, and the input of the operation keys 3A to 3C. Functions, volume key 3D input function, power key 3E input function, first wireless unit 14 communication function, second wireless unit 15 reception function, third wireless unit 16 communication function, battery 13 charging function, etc. is there.

  For example, in the normal mode, when the first wireless unit 14 detects an incoming call from another terminal, the controller 21 executes the incoming call function as a main function. In addition, the controller 21 causes the lamp 6, the speaker 9, and the vibrator 11 to execute a notification function as an additional function.

<Sleep mode>
The sleep mode is a mode in which some of the additional functions of the electronic device 1 are restricted in order to reduce the power consumption of the electronic device 1 when the power of the electronic device 1 is on. In the sleep mode, some of the limited additional functions are, for example, display functions of the display 2.

  For example, when the electronic device 1 is in the normal mode, the controller 21 shifts the electronic device 1 from the normal mode to the sleep mode when a user operation on the operation key 3A or the like is not detected for a predetermined time. The controller 21 may execute the application in the background during the sleep mode. The controller 21 may execute the incoming call function when the first wireless unit 14 detects an incoming call from another terminal. At this time, the controller 21 causes the lamp 6, the speaker 9, and the vibrator 11 to execute a notification function as an additional function.

<Power off mode>
The power-off mode is a mode in which the main function of the electronic device 1 is restricted while the power of the electronic device 1 is in an off state. Note that, in the power-off mode, only the input function of the power key 3E for starting up the electronic device 1 and the charging function of the battery 13 among the additional functions of the electronic device 1 can be executed.

  For example, when the electronic device 1 is in the power-off mode, the controller 21 activates the electronic device 1 when detecting a user operation on the power key 3E. For example, when the controller 21 detects that the USB cable of the charger is connected to the connector 12 during the power-off mode, the controller 21 charges the battery 13.

  For example, when a user who is a child brings the electronic device 1 into an airplane, the electronic device 1 may be required to be turned off. At this time, for example, the guardian operates a menu for the guardian set in advance in the electronic device 1 to put the electronic device 1 in the power-off mode.

<Pseudo power off mode>
The pseudo power-off mode is a mode in which the power of the electronic device 1 is on and some functions of the normal mode are limited. In other words, in the pseudo power-off mode, the electronic device 1 is turned on and the specific function of the electronic device 1 is maintained to be executable while a part of the functions of the normal mode is restricted to supply power to the user. This is a mode for the electronic device 1 to wear as if is in an off state. For example, in a public place, the pseudo power-off mode is used when it is desired to disguise as if the power is off while maintaining the security buzzer function and answering machine function as specific functions. The In the present embodiment, it is assumed that the specific functions maintained to be executable in the pseudo power-off mode are a security buzzer function and an answering machine function. Further, the specific function maintained to be executable may include the communication function of the first wireless unit 14 or the reception function of the second wireless unit 15. Some functions that are restricted in the pseudo power-off mode include, for example, the display function of the display 2, the notification function of the speaker 9, the notification function of the vibrator 11, the notification function of the lamp 6, the input function of the touch sensor 2B, and the light 8 And at least one of input functions of some hard keys (for example, operation keys 3A to 3C).

  For example, when the controller 21 detects that the power key 3E is pressed for a long time (for example, 1 second or longer) while the electronic device 1 is in the normal mode, the controller 21 shifts the electronic device 1 from the normal mode to the pseudo power-off mode. Let For example, the controller 21 turns off the display function of the display 2 or disables user operations on the operation keys 3A to 3C and the volume key 3D. In this way, the electronic device 1 can be disguised as if it is in a power-off state for the user. In addition, even if the electronic device 1 is in the pseudo power-off mode, the security buzzer function and the answering machine function are maintained in an executable state. Therefore, even if the electronic device 1 is in the pseudo power-off mode, the safety of the user can be ensured.

<System error resolution process>
By the way, in a device in which software is incorporated, a system error may occur due to a state in which the software cannot operate normally. The usual method taken to resolve system errors is, for example, restart. The restart is, for example, turning off the power of the device, resetting the current setting, and then starting the device. The restart at this time includes, for example, a hardware reboot that once cuts off the power supply to the hardware and a software reboot that ends the software once while the power supply to the hardware is maintained.

  Software is also incorporated in the electronic device 1 having the pseudo power-off mode. Accordingly, a system error may occur when the electronic device 1 having the pseudo power-off mode is in the pseudo power-off mode. In this case, if the electronic device 1 solves the system error by a normal method, the pseudo power-off mode is canceled when the current setting is reset by turning off the power of the electronic device. Therefore, even if the electronic device is in the pseudo power-off mode before the system error occurs, the electronic device returns to the normal mode after restarting.

  Furthermore, system errors occur accidentally. That is, the user often does not notice even if a system error occurs. In addition, the pseudo power-off mode is a mode for the electronic device 1 to disguise as if the power is off to the user in a public place as described above. That is, the user often does not pay attention to the electronic device 1 during the pseudo power-off mode of the electronic device 1. Therefore, when a system error that occurs during the pseudo power-off mode of the electronic device 1 is solved by a normal method, even if the electronic device 1 returns to the normal mode by restarting, the user does not notice that. There are many. In other words, a situation may occur in which the setting of the electronic device 1 is changed to the normal mode without the user's knowledge. In such a case, for example, a situation may occur in which the electronic device 1 performs an operation not intended by the user, such as emitting a ring tone, in a public place.

  In order to avoid the above situation, in this embodiment, when the electronic device 1 is restarted due to a system error when the electronic device 1 is in the pseudo power-off mode, the electronic device 1 Is returned to the pseudo power-off mode. Details of this processing will be described later with reference to FIG.

  Furthermore, the controller 21 returns the electronic device 1 to the normal mode when the electronic device 1 is restarted due to a system error when the electronic device 1 is in the normal mode (or sleep mode). Details of this processing will be described later with reference to FIG.

  The controller 21 may return the electronic device 1 to the normal mode when the electronic device 1 is restarted due to a user operation when the electronic device 1 is in the pseudo power-off mode. When restarting the electronic device 1 due to a user operation, for example, the user presses the power key 3E for a long time (for example, 3 seconds or more) to turn off the electronic device 1, and then the user further presses the power key 3E. This is when the electronic device 1 is activated by pressing it for a long time (for example, 1 second or longer). This user operation is often performed when the user attempts to cancel the pseudo power-off mode of the electronic device 1 and the pseudo power-off mode cannot be canceled due to a system error. In other words, under this circumstance, the user is aware of the system error. Therefore, even when the electronic device 1 returns to the normal mode, the electronic device 1 does not perform an operation unintended by the user, such as generating a ring tone as described above. Further, by returning to the normal mode, the user can quickly know that the restart of the electronic device 1 has been completed from a predetermined image displayed on the display 2 in the normal mode, for example. In addition, since the user can immediately use the electronic device 1 by returning to the normal mode, the electronic device 1 is excellent in user convenience.

  In addition, when the electronic device 1 is in the pseudo power-off mode, the controller 21 turns off the electronic device 1 due to a decrease in the remaining amount of the battery 13, and then activates the electronic device 1. May return the electronic device 1 to the normal mode. In this case, when the controller 21 determines that the remaining amount of the battery 13 is lower than the threshold value, the controller 21 may turn off the electronic device 1.

  When the electronic device 1 is restarted in the above situation, for example, the battery 13 is being charged or after the battery 13 is completely charged. The battery 13 is charged by connecting the USB cable of the charger to the connector 12 by the user. Therefore, when the electronic device 1 is activated under such a situation, the user is often not in a public place. For this reason, even when the electronic device 1 returns to the normal mode, the situation where the electronic device 1 performs an unintended operation of the user, such as emitting a ring tone, in a public place as described above does not occur. Further, by returning to the normal mode, the user can quickly know that the restart of the electronic device 1 has been completed from a predetermined image displayed on the display 2 in the normal mode, for example. In addition, since the user can immediately use the electronic device 1 by returning to the normal mode, the electronic device 1 is excellent in user convenience.

[System operation]
FIG. 4 is a flowchart showing the operation of the electronic device 1 according to the embodiment of the present invention. In the following, it is assumed that a system error has occurred in the electronic device 1 before the process of step S1.

  When detecting a system error (step S1), the controller 21 determines whether or not the current mode of the electronic device 1 is the pseudo power-off mode (step S2). When the controller 21 determines that the current mode of the electronic device 1 is the pseudo power-off mode (step S2: Yes), the controller 21 proceeds to the process of step S3. On the other hand, when the controller 21 determines that the current mode of the electronic device 1 is not the pseudo power-off mode (step S2: No), that is, the current mode of the electronic device 1 is the normal mode (or sleep mode). If it is determined, the process proceeds to step S5.

  In the process of step S3, the controller 21 turns off the electronic device 1 and resets the current setting. Thereafter, the controller 21 activates the electronic device 1 to return to the pseudo power-off mode (step S4).

  As described above, in the present embodiment, when the electronic device 1 is restarted due to a system error when the electronic device 1 is in the pseudo power-off mode, the electronic device 1 is switched to the pseudo power source by the processing of steps S1 to S4. Return to off mode. Thereby, the situation where the setting of the electronic device 1 is changed to the normal mode without the user's knowledge can be prevented. Therefore, in this embodiment, the improved electronic device 1 can be provided.

  In the process of step S5, the controller 21 turns off the electronic device 1 and resets the current setting. Thereafter, the controller 21 activates the electronic device 1 to return to the normal mode (step S6).

  As described above, when the electronic device 1 is restarted due to a system error when the electronic device 1 is in the normal mode (or sleep mode) in the present embodiment by the processing of steps S1, S2, S5, and S6. The electronic device 1 is returned to the normal mode. Thereby, even if a system error occurs when the user is using the electronic device 1 in the normal mode, the user can continue to use the electronic device 1 in the normal mode again. Therefore, the electronic device 1 is excellent in user convenience.

  In the process of step S2, the controller 21 may determine whether or not the current mode of the electronic device 1 is the normal mode (or sleep mode). In this case, when the controller 21 determines that the current mode of the electronic device 1 is the normal mode (or sleep mode), the process proceeds to step S5. On the other hand, when the controller 21 determines that the current mode of the electronic device 1 is not the normal mode (or sleep mode), that is, when the current mode of the electronic device 1 is determined to be the pseudo power-off mode, the step The process proceeds to S3.

  As described above, in the electronic device 1 according to the present embodiment, when the electronic device 1 is in the pseudo power-off mode, when the electronic device 1 is restarted due to a system error, the electronic device 1 is turned off in the pseudo power-off mode. Return to mode. Thereby, the situation where the setting of the electronic device 1 is changed to the normal mode without the user's knowledge can be prevented. Therefore, in this embodiment, the improved electronic device 1 can be provided.
