The illustrated electronic device 10 is a laptop (notebook) personal computer including a main body 20 (an example of a first main body) and a cover 30 (an example of a second main body). The cover 30 is relatively rotatable with respect to the main body 20 by a hinge 25 between a closed state (an example of the second embodiment) and an open state (an example of the first embodiment). Here, the closed state is a state in which the side of the first display unit 140 provided in the cover unit 30 covers the main unit 20 and the main unit 20 and the cover unit 30 are overlapped with each other (FIGS. 2, FIG. 3 (b)). That is, the closed state refers to a state in which the electronic device 10 is in a form in which part or all of the first display unit 140 is physically invisible. The open state is a state in which the cover unit 30 is rotated by a predetermined angle or more from the closed state, and the first display unit 140 provided on the cover unit 30 is exposed and visible (FIGS. 1 and 3A). reference). That is, the open state is a state in which the electronic device 10 is in a form in which the entire first display unit 140 is physically visible. The second display section 240 provided on the main body section 20 is configured to be visible in both the open state and the closed state.

  The main body 20 has a flat-shaped housing extending in the left-right direction and the front-back direction. A motherboard (substrate) on which electronic components are mounted, a battery, and the like are provided inside the housing. The main body 20 is rotatably connected to the cover 30 via a hinge 25. The main body 20 and the cover 30 may be separable.

  The main body unit 20 includes a second display unit 240, a touch sensor 250, a power switch 20a, an input unit 20b, and a detection unit 20c. The second display unit 240 includes a liquid crystal display (LCD), an organic EL (Electro Luminescence) display, and the like. The second display unit 240 has a rectangular shape that is long in the left-right direction and short in the front-rear direction, and is arranged at a position closer to the hinge 25 than the input unit 20b. The second display unit 240 displays display information based on a process based on the OS2. The input unit 20b is a keyboard or the like.

  The touch sensor 250 is arranged at a position overlapping the display surface of the second display unit 240, and is configured as one touch panel by the second display unit 240 and the touch sensor 250. The surface of the touch sensor 250 is covered with a transparent cover 20f (see FIGS. 3A and 3B). The touch sensor 250 includes, for example, a capacitance-type sensor and the like, and detects a position touched by the user. Further, the touch sensor 250 is transparent, and the second display unit 240 can be visually recognized through the transparent cover 20f and the touch sensor 250. As described above, the touch sensor 250 detects a user's operation input on the display surface of the second display unit 240 (see FIG. 3A). FIG. 3A is a diagram of the electronic device 10 in an open state as viewed from a side.

  The cover unit 30 includes a first display unit 140 and a touch sensor 150. The first display unit 140 includes a liquid crystal display, an organic EL display, and the like. The first display section 140 displays display information obtained by processing based on the OS1. The touch sensor 150 is disposed at a position overlapping the display surface of the first display unit 140, and is configured as one touch panel by the first display unit 140 and the touch sensor 150. The touch sensor 150 includes, for example, a capacitance-type sensor and the like, and detects a position touched by the user. As described above, the touch sensor 150 detects a user's operation input on the display surface of the first display unit 140. Note that the touch sensor 150 may not be provided.

  In addition, the cover unit 30 has a transparent area A including at least an area closer to the hinge 25 than the first display unit 140. For example, the transparent area A is provided at a position that covers the second display section 240 of the main body section 20 when the cover section 30 is closed. A touch sensor 260 is provided in a part of the transparent area A.

  The detection section 20c provided at the end of the main body section 20 and the detection target section 30c provided at the end of the cover section 30 are provided at positions facing each other in the closed state. For example, a magnetic sensor such as a Hall sensor can be used as the detection unit 20c. As the detection target unit 30c, for example, a magnet can be used. The detection unit 20c detects an open state and a closed state of the cover unit 30 by detecting a change in a magnetic field generated by the detection target unit 30c by moving the cover unit 30 between the open state and the closed state. be able to.

This figure shows a closed state in which the cover 30 is rotated around the hinge 25 from the open state shown in FIG. 1 and the cover 30 and the main body 20 are overlapped. As shown, in the closed state, the transparent area A overlaps the position of the second display 240. That is, the transparent area A covers the second display unit 240. Therefore, the user can visually recognize the second display unit 240 through the transparent area A. In the closed state, the touch sensor 260 provided in the transparent area A is arranged at a position overlapping the display surface of the second display unit 240. Therefore, touch sensor 260 is configured as second display unit 240 and one touch panel instead of touch sensor 250, and detects a user operation on the display surface of second display unit 240 (see FIG. 3B). . FIG. 3B is a diagram of the electronic device 10 in the closed state as viewed from the side.

  As described above, in the open state, the electronic device 10 displays the display information based on the process based on the OS1 on the first display unit 140, and displays the display information based on the process based on the OS2 on the second display unit 240. It is possible to receive a user operation on the display surface of. On the other hand, in the closed state, the electronic device 10 causes the OS 1 to transition to the standby state or the stop state. That is, in the closed state, the electronic device 10 displays the display information obtained by the process based on the OS2 on the second display unit 240 without performing the process based on the OS1, and accepts a user operation on the second display unit 240.

(Block Configuration of Electronic Device 10)
FIG. 4 is a block diagram illustrating a configuration example of the electronic device 10 according to the present embodiment. The electronic device 10 includes a first processing unit 100 including a first processor that executes a process based on the OS1, a second processing unit 200 including a second processor that executes a process based on the OS2, a power supply unit 300, It has. In addition, the electronic device 10 includes a first display unit 140 that displays display information obtained by processing based on the OS 1, and a touch sensor 150 that receives an operation on a display surface of the first display unit 140. In addition, the electronic device 10 includes a second display unit 240 that displays display information by a process based on the OS2, a touch sensor 250 that receives an operation on a display surface of the second display unit 240 in an open state, and a touch sensor that receives an operation in a closed state. 260.

  The OS 1 is, for example, Windows (registered trademark) as described above. The first processor includes a CPU (Central Processing Unit) that executes a process based on the OS 1 and a chipset (for example, PCH: Platform Controller Hub). Hereinafter, the first processor is referred to as “CPU 110” for convenience.

  OS2 is, for example, Android (registered trademark) as described above. The second processor includes an SOC (System On a Chip) that executes a process based on the OS2. This SOC is obtained by integrating a plurality of ICs such as a CPU, a GPU, and a chip set into one chip. Hereinafter, the second processor is referred to as “SOC 210” for convenience.

  It should be noted that the OS1, OS2, CPU 110, and SOC 210 described in the present embodiment are merely examples, and the present invention is not limited to these, and may be configured to include any OS and processor.

  The first processing unit 100 includes a CPU 110, an EC 120, a first display control unit 130, and the like. CPU 110 executes a process based on OS1.

  The first display control unit 130 controls the display of the display information by the processing based on the OS 1 on the first display unit 140 under the control of the CPU 110. For example, the CPU 110 causes the first display unit 140 to display the display information obtained by the process based on the OS 1 via the first display control unit 130. In addition, the CPU 110 obtains, from the touch sensor 150, a detection result of a user operation input to the display surface of the first display unit 140.

  The EC 120 is an example of a control unit that monitors and controls various devices (peripheral devices, sensors, and the like) regardless of the processing of the CPU 110, and is an embedded controller in which a microcomputer is embedded. The EC 120 has functions such as battery management, power management, and a keyboard controller. For example, by communicating with the power supply unit 300, the EC 120 obtains information on the state of the battery (such as the remaining capacity) from the power supply unit 300, and issues an ON / OFF instruction for power supply to each unit to the power supply unit 300. Do it for Further, the EC 120 acquires an operation signal from the input unit 20b based on an operation input to the input unit 20b (for example, a keyboard). Then, the EC 120 transmits the obtained operation input information to one of the first processing unit 100 and the second processing unit 200, which is performing the active processing. Further, the EC 120 performs a process for controlling the operating state of each OS for each of the first processing unit 100 and the second processing unit 200. Details of the operation state control processing will be described later.

  The second processing unit 200 includes an SOC 210, a second display control unit 230, and the like. The SOC 210 executes a process based on the OS2.

  The second display control unit 230 controls the display of the display information by the processing based on the OS 2 on the second display unit 240 under the control of the SOC 210. For example, the SOC 210 causes the second display unit 240 to display the display information obtained by the process based on the OS 2 via the second display control unit 230. The SOC 210 also acquires, from the touch sensor 250 or the touch sensor 260, a detection result of a user operation input to the display surface of the second display unit 240.

  For example, the SOC 210 acquires a detection result of a user's operation input on the display surface of the second display unit 240 from the touch sensor 250 or the touch sensor 260 via USB communication. The SOC 210 is connected to the touch sensor 250 and the touch sensor 260 via the switching unit 215 via a USB communication path. The switching unit 215 is connected to the signal line (LID_CLOSE) from the detection unit 20c. When the detection unit 20c has not detected the closed state (that is, when the detection unit 20c is in the open state), the switching unit 215 receives the signal from the touch sensor 250. Switch to enable the route. On the other hand, when the detection unit 20c detects the closed state, the switching unit 215 performs switching so that the path from the touch sensor 260 is valid.

  In addition, between the SOC 210 of the second processing unit 200 and the CPU 110 of the first processing unit 100, information (applications) of each other (serial communication) such as USB (Universal Serial Bus) or I2C (Inter-Integrated Circuit) is used. Information such as the operating status of the device). Further, the EC 120 communicates with the CPU 110 using serial communication such as LPC (Low Pin Count), and communicates with the SOC 210 using serial communication such as I2C, so that the operating state of each OS is changed. Or instructs each OS to change the operating state. Note that the communication standards used for each of the above communications are merely examples, and the present invention is not limited to these.

  The power supply unit 300 supplies electric power to each unit included in the electronic device 10 based on electric power supplied from a built-in battery (battery) (not shown) or an AC adapter, or built-in based on electric power supplied from an AC adapter. Control the charging of the battery. For example, the power supply unit 300 monitors the battery voltage, detects the amount of charge (remaining capacity) of the battery, detects and controls the charging voltage and charging current, and controls ON / OFF of power supply to each unit. It includes a circuit (PMIC: Power Management Integrated Circuit) and the like.

(About operation state control processing)
Next, in this embodiment, an operation state control process for controlling the operation states of the two types of OSs will be described in detail. The electronic device 10 performs various processes using two types of OSs, OS1 and OS2, but the processes are different between an open state and a closed state. For example, in the open state, both the first display unit 140 and the second display unit 240 are visible. Therefore, in the open state, the user can use both the OS1 and the OS2. On the other hand, in the closed state, the first display unit 140 is not visible, and only the second display unit 240 is visible. Therefore, in the closed state, the user can use only OS2. Therefore, when an operation input to the power switch 20a is performed, the electronic device 10 controls the operating state of each OS differently based on whether the operating state is the open state or the closed state. The power switch 20a is an example of a receiving unit that receives an operation input for activating the operating state of the OS1 or the operating state of the OS2 to the first operating state. The power switch 20a is provided on, for example, a side surface of the electronic device 10 as an operation element that can be operated in either the open state or the closed state (see FIG. 1).

  Note that the first operation state is a normal operation state in which processing based on the OS can be executed without any particular limitation, and corresponds to, for example, an S0 state defined by ACPI (Advanced Configuration and Power Interface). To activate to the normal operation state means to activate and transition from the second operation state in which at least a part of the processing based on the OS is restricted to the normal operation state. The second operation state is a standby state or a stopped state in which at least a part of the processing based on the OS is restricted. The standby state is, for example, a screen OFF state, a state in which power consumption is lower than in a normal operation state, or a state in which power supply to a processor (for example, the CPU 110 or the SOC 210) is stopped. The standby state corresponds to, for example, a modern standby in Windows (registered trademark) or an S3 state (sleep state) defined by ACPI. The stopped state is, for example, a hibernation state or a shut down state, and corresponds to the S4 state or the S5 state defined by ACPI.

  As shown in FIG. 4, the EC 120 is connected to the signal line (LID_CLOSE) from the detection unit 20c, and determines whether the EC 120 is in the open state or the closed state based on the detection result of the detection unit 20c. Further, the EC 120 determines whether or not the power switch 20a has received an operation input based on the operation input signal acquired from the power switch 20a. For example, when the power switch 20a receives an operation input (that is, when the operation of pressing down the power switch 20a (ON) is performed), the EC 120 acquires an operation input signal indicating that the operation has been performed from the power switch 20a. On the other hand, when the power switch 20a does not receive an operation input (that is, when the operation of pressing down the power switch 20a (ON) is not performed), the EC 120 acquires an operation input signal indicating that the operation is not performed from the power switch 20a. I do. The operation input signal indicating that the operation (ON) of pressing down the power switch 20a is, for example, a pulse-shaped signal whose signal level changes from High to Low for a predetermined period, and then returns to High. The period during which the power supply SW 20a is Low corresponds to, for example, a duration during which the power switch 20a is pressed. On the other hand, the operation input signal when the operation (ON) of pressing down the power supply SW 20a is not operated is a signal whose signal level remains High.

  For example, when the power switch 20a receives an operation input in the open state, the EC 120 activates both OS1 and OS2 to transition to the normal operation state. For example, when the EC 120 acquires an operation input signal indicating that an operation (ON) of pressing the power SW 20 a in the open state from the power SW 20 a, the power SW 20 a responds to the PWR_ON signal connected to the CPU 110 from the EC 120. An operation ON signal indicating that the operation has been performed is output (PWR_ON: ON), and an operation ON signal indicating that the power supply SW 20 a has been operated is also output in response to the AUX_WAKE signal connected to the SOC 210 (AUX_WAKE: ON). ).

  The above-mentioned operation ON signal is, for example, a pulse-like signal whose signal level changes from low to high for a predetermined period, and thereafter returns to low. The High period corresponds to, for example, a continuation time during which the power switch 20a is pressed. That is, here, the operation ON signal is a signal obtained by inverting the operation input signal output from the power supply SW 20a. The specifications of the operation input signal and the operation ON signal described above are merely examples, and the present invention is not limited thereto.

  When acquiring the operation ON signal from the EC 120, the CPU 110 activates the OS 1 from the standby state or the stop state and makes the OS 1 transition to the normal operation state. Further, when the SOC 210 acquires the operation ON signal from the EC 120, the SOC 210 activates the OS 2 from the standby state or the stop state and makes the OS 2 transition to the normal operation state. At this time, the EC 120 may instruct the power supply unit 300 to supply power necessary for operating the OS1 and OS2 in the normal operation state.

  On the other hand, for example, in the closed state, when the power switch 20a receives an operation input in the closed state, the EC 120 activates only the OS2 and makes a transition to the normal operation state. Specifically, when the EC 120 acquires from the power supply SW 20 a an operation input signal indicating that the operation of pressing the power supply SW 20 a (ON) has been performed, the EC 120 outputs an operation ON signal only to the AUX_WAKE connected to the SOC 210. (AUX_WAKE: ON). When the SOC 210 acquires the operation ON signal from the EC 120, the SOC 210 activates the OS 2 from the standby state or the stop state and makes the OS 2 transition to the normal operation state. At this time, the EC 120 may instruct the power supply unit 300 to supply power necessary for the OS 2 to operate in the normal operation state.

  FIG. 5 is a flowchart illustrating an example of an operation state control process when the power switch 20a receives an operation input. With reference to FIG. 5, the operation of the operation state control processing when power supply SW 20a receives an operation input when OS1 and OS2 are in the standby state or the stopped state will be described.

(Step S101) The EC 120 determines whether or not an operation (ON) of pressing the power switch 20a has been performed based on an operation signal obtained from the power switch 20a. When the operation input signal indicating that the operation of pressing the power switch 20a (ON) is performed is obtained from the power switch 20a (YES), the EC 120 proceeds to the process of step S103. On the other hand, when the operation input signal indicating that the operation of pressing down the power switch 20a (ON) is not obtained from the power switch 20a (NO), the EC 120 performs the process of step S101 again.

(Step S103) The EC 120 determines whether or not the cover unit 30 is open based on the detection result of the detection unit 20c. When it is determined that the EC 120 is in the open state (YES), the process proceeds to step S105. On the other hand, if it is determined that the EC 120 is in the closed state (NO), the process proceeds to step S109.

(Step S105) The EC 120 outputs an operation ON signal indicating that the power switch 20a has been operated in response to the PWR_ON signal connected to the CPU 110 (PWR_ON: ON), and responds to the AUX_WAKE signal connected to the SOC 210. Output an operation ON signal indicating that the power switch 20a has been operated (AUX_WAKE: ON). Then, the process proceeds to step S107.

(Step S107) Upon acquiring the operation ON signal from the EC 120, the CPU 110 activates the OS 1 from the standby state or the stop state and makes the OS 1 transition to the normal operation state. Further, when the SOC 210 acquires the operation ON signal from the EC 120, the SOC 210 activates the OS 2 from the standby state or the stop state and makes the OS 2 transition to the normal operation state.

(Step S109) The EC 120 outputs an operation ON signal only to AUX_WAKE connected to the SOC 210 (AUX_WAKE: ON). Then, the process proceeds to step S111.

(Step S111) When the SOC 210 acquires the operation ON signal from the EC 120, the SOC 210 activates the OS 2 from the standby state or the stop state, and makes a transition to the normal operation state.

  In this manner, the EC 120 activates both OS1 and OS2 to the normal operation state when the power switch 20a receives the operation input in the open state, and activates the OS2 when the power switch 20a receives the operation input in the closed state. Only the normal operation state is activated.

  Thus, in a system in which a plurality of OSs are mounted, the electronic device 10 can appropriately control the operating state of each OS according to whether the cover unit 30 is in the open state or the closed state. Therefore, the electronic device 10 can appropriately control a system equipped with a plurality of OSs.

  For example, the electronic device 10 includes the main body 20 in which the second display 240 is disposed, and the cover 30 in which the first display 140 is disposed. The cover unit 30 is relatively movable between an open state where the surface on which the second display unit 240 is arranged is not covered and a closed state where the surface where the second display unit 240 is arranged. The cover section 30 has a transparent area A at a position covering the second display section 240 in the closed state.

  Thereby, in the electronic device 10, the user can operate the cover unit 30 in the open state or the closed state, and in the open state, the user can visually recognize both the first display unit 140 and the second display unit 240. When both OS1 and OS2 are operated and only the second display unit 240 is visible to the user in the closed state, only OS2 can be operated. Therefore, the electronic device 10 can appropriately control the operation state of each OS according to whether the cover unit 30 is in the open state or the closed state.

Next, referring to FIG. 6, when both OS1 and OS2 are in the normal operation state in the open state (for example, after the processing of step S107 in FIG. 5), when OS1 transitions to the standby state or the stop state. The operation of the operation state control process will be described.
FIG. 6 is a flowchart illustrating an example of the operation state control processing in the open state.

(Step S121) The EC 120 obtains information on the operating state of the OS1 from the CPU 110, and determines whether the OS1 has transitioned to the standby state or the stopped state. For example, when the user performs an operation to instruct a shutdown, the OS 1 transitions to a stop state. In addition, the OS 1 transitions to the standby state when the no-operation state continues for a preset time or when the user performs an operation to instruct the transition to the standby state. If the EC 120 determines that the OS 1 has transitioned to the standby state or the stopped state (YES), the EC 120 proceeds to the process of step S123. On the other hand, when the EC 120 determines that the OS 1 has not transitioned to the standby state or the stopped state (that is, remains in the normal operation state) (NO), the EC 120 performs the process of step S121 again.

(Step S123) When the EC 120 determines that the OS 1 has transitioned to the standby state or the stopped state, the EC 120 transmits to the SOC 210 an instruction to cause the OS 2 to transition to the same operation state (standby state or the stopped state) as the OS 1. In response, SOC 120 causes OS2 to transition to the standby state or the stop state similarly to OS1.

  As described above, when both the OS1 and the OS2 are activated in the normal operation state in the open state, the EC 120 transits to the standby state or the stop state in which at least a part of the processing of the OS1 is more restricted than in the normal operation state. Accordingly, the OS 2 is shifted to the standby state or the stop state.

  Accordingly, when the user suspends or terminates the use, the electronic device 10 merely brings the OS1 into the standby state or the stop state, and the OS2 also goes into the standby state or the stop state in conjunction with the user.

Next, referring to FIG. 7, when both OS1 and OS2 are in the normal operation state in the open state (for example, after the processing of step S107 in FIG. 5), cover unit 30 is rotated to transition to the closed state. The operation of the operation state control process when the operation is performed will be described.
FIG. 7 is a flowchart illustrating an example of the operation state control processing when the state transits from the open state to the closed state.

(Step S131) The EC 120 determines whether or not a transition has been made from the open state to the closed state based on the detection result of the detection unit 20c. When the EC 120 determines that the state has transitioned from the open state to the closed state (YES), the process proceeds to step S133. On the other hand, when it is determined that the EC 120 has not transitioned from the open state to the closed state (that is, it remains in the open state) (NO), the EC 120 performs the process of step S131 again.

(Step S133) When the EC 120 determines that the state has transitioned from the open state to the closed state, the EC 120 transmits an instruction to the CPU 110 to transition only the OS 1 to the standby state. In response, CPU 110 causes OS1 to transition to the standby state.

  In step S133, if the EC 120 determines that the state has transitioned from the open state to the closed state, the EC 120 may transmit an instruction to the CPU 110 to transition only the OS1 to the stop state. In this case, the CPU 110 causes the OS 1 to transition to the stop state.

  As described above, when both the OS1 and the OS2 are activated to the normal operation state in the open state, the EC 120 limits the OS1 to at least a part of the processing compared to the normal operation state according to the closed state. To a standby state or a stopped state.

  Thus, when the user wants to use only OS2, the electronic device 10 can automatically shift the OS1 to the standby state or the stop state by only closing the cover unit 30 so that only the OS2 can be used. Therefore, the convenience is good, wasteful power consumption can be suppressed, and the use time of the battery can be extended.

  Note that the EC 120 causes the OS 1 to transition to the standby state or the stop state in response to the transition from the open state to the closed state, and then, if the no-operation state continues for a preset time, the OS 2 also sets the standby state or the stop state. The state may be transited.

  Further, in the example described with reference to FIG. 7, only OS1 is changed to the standby state or the stop state in response to the change from the open state to the closed state, but both OS1 and OS2 are set to the standby state or the stop state. The transition may be made to

  Next, the operation of the operation state control processing when the cover unit 30 is turned from the closed state to the open state will be described. For example, the EC 120 determines whether or not a transition has been made from the closed state to the open state based on the detection result of the detection unit 20c, and activates OS1 and OS2 when it is determined that the transition has been made from the closed state to the open state. Transition to the normal operation state. Here, when only the OS2 is in the normal operation state when the EC 120 is in the closed state (for example, after the processing in step S111 in FIG. 5 or step S133 in FIG. 7), the EC 120 activates the OS1 to enter the normal operation state. A transition is made, and the OS 2 remains in the normal operation state. On the other hand, when both the OS1 and the OS2 are in the standby state or the stop state in the closed state, the EC 120 activates both the OS1 and the OS2 to transition to the normal operation state. Thus, the electronic device 10 can make both OSs usable by the user changing from the closed state to the open state.

Note that the EC 120 may make the control when the OS 2 transitions from the closed state to the open state different depending on whether or not the OS 2 is in the normal operation state when in the closed state. For example, in the closed state, only when the OS1 is in the standby state or the stopped state and only the OS2 is in the normal operation state (for example, after the processing of the step S111 in FIG. 5 or the step S133 in FIG. 7), the state transits to the open state. OS1 may be activated in response to the transition to the normal operation state.
FIG. 8 is a flowchart illustrating an example of the operation state control processing when the state transits from the closed state to the open state.

(Step S141) The EC 120 determines whether or not a transition has been made from the closed state to the open state based on the detection result of the detection unit 20c. When it is determined that the EC 120 has transitioned from the closed state to the open state (YES), the EC 120 proceeds to the process of step S143. On the other hand, when it is determined that the EC 120 has not transitioned from the closed state to the open state (that is, it remains in the closed state) (NO), the EC 120 performs the process of step S141 again.

(Step S143) The EC 120 acquires information indicating the operating state of the OS 2 from the SOC 120, and determines whether the OS 2 is in the normal operating state. If the EC 120 determines that the OS 2 is in the normal operation state (YES), the EC 120 proceeds to the process of step S145. On the other hand, when the EC 120 determines that the OS 2 is in the standby state or the stopped state (NO), the EC 120 ends the process without activating any of the OS 1 and the OS 2.

(Step S145) When the EC 120 determines that the OS 1 has transitioned from the closed state to the open state, the EC 120 transmits an instruction to the CPU 110 to transition the OS 1 from the standby state or the stop state to the normal operation state. In response, the CPU 110 activates the OS 1 to transition to the normal operation state.

  Thus, when the OS 120 is in the standby state or the stop state in the closed state and the OS 2 is activated in the normal operation state, the EC 120 activates the OS 1 to the normal operation state in response to the open state. To On the other hand, when OS1 and OS2 are in the standby state or the stopped state in the closed state, the EC 120 keeps the OS1 and OS2 in the standby state or the stopped state even when the EC1 is opened.

  Accordingly, the electronic device 10 controls whether or not to activate the OS1 when the user switches from the closed state to the open state, depending on whether or not the electronic device 10 has been used in the closed state. . For example, when the user wants to use OS1 rather than OS2 while using OS2 in the closed state, OS1 is started only by opening it, which is convenient.

[Second embodiment]
Next, a second embodiment of the present invention will be described.
In the present embodiment, a configuration in which the operating state of each OS is controlled in consideration of the remaining capacity of the battery will be described. Note that the basic configuration of the electronic device 10 according to the present embodiment is the same as that of the first embodiment illustrated in FIG. 1, and thus, a characteristic process in the present embodiment will be described. In the present embodiment, the EC 120 detects the remaining capacity of the battery based on the information on the state of the battery obtained from the power supply unit 300, and limits transition of the OS1 or OS2 to the normal operation state based on the remaining capacity of the battery. I do. For example, when OS1 is Windows (registered trademark) and OS2 is Android (registered trademark), operating OS1 generally consumes higher power than operating OS2. Therefore, the EC 120 may restrict the OS 1 from being in the normal operation state when the remaining capacity of the battery becomes equal to or less than the predetermined value. The above-mentioned predetermined value is a threshold value of the remaining battery capacity which is set in advance to determine whether or not to limit the OS 1 to the normal operation state.

  For example, when the power switch 20a receives an operation input when the OS1 and OS2 are in the standby state or the stop state, in the first embodiment shown in FIG. 5, in the case of the open state, both the OS1 and OS2 are in the normal operation state. And in the closed state, only OS2 was activated to the normal operation state. On the other hand, in the present embodiment, when the remaining capacity of the battery is equal to or less than the predetermined value, only OS2 is activated to the normal operation state even in the open state.

FIG. 9 is a flowchart illustrating an example of an operation state control process when the power switch 20a according to the present embodiment receives an operation input.
(Step S201) The EC 120 determines whether or not an operation (ON) of pressing the power switch 20a is performed based on an operation signal acquired from the power switch 20a. When the EC 120 acquires from the power switch 20a an operation input signal indicating that the operation of pressing the power switch 20a (ON) has been performed (YES), the process proceeds to step S203. On the other hand, when the operation input signal indicating that the operation of pressing the power switch 20a (ON) is not obtained from the power switch 20a (NO), the EC 120 performs the process of step S201 again.

(Step S203) When the EC 120 acquires an operation signal indicating that the operation of pressing the power switch 20a (ON) has been performed from the power switch 20a, the cover unit 30 is in the open state based on the detection result of the detection unit 20c. It is determined whether or not. When it is determined that the EC 120 is in the open state (YES), the process proceeds to step S205. On the other hand, when it is determined that the EC 120 is in the closed state (NO), the process proceeds to step S211.

(Step S205) The EC 120 determines whether or not the remaining capacity of the battery is equal to or less than a predetermined value (the remaining amount is low) based on the information on the state of the battery obtained from the power supply unit 300. When the EC 120 determines that the remaining capacity of the battery is equal to or less than the predetermined value (YES), the process proceeds to step S211. On the other hand, when the EC 120 determines that the remaining capacity of the battery is not less than the predetermined value (NO), the process proceeds to step S207.

(Step S207) The EC 120 outputs an operation ON signal indicating that the power switch 20a has been operated in response to the PWR_ON signal connected to the CPU 110 when the battery is open and the remaining battery charge is larger than a predetermined value. At the same time (PWR_ON: ON), an operation ON signal indicating that the power switch 20a has been operated is also output to the AUX_WAKE signal connected to the SOC 210 (AUX_WAKE: ON). Then, the process proceeds to step S209.

(Step S209) Upon acquiring the operation ON signal from the EC 120, the CPU 110 activates the OS 1 from the standby state or the stopped state to transition to the normal operation state. Further, when the SOC 210 acquires the operation ON signal from the EC 120, the SOC 210 activates the OS 2 from the standby state or the stop state and makes the OS 2 transition to the normal operation state.

(Step S211) The EC 120 outputs an operation ON signal only to the AUX_WAKE connected to the SOC 210 when the remaining battery capacity is equal to or less than a predetermined value even in the closed state or the open state (AUX_WAKE). : ON). Then, the process proceeds to step S213.

(Step S213) When the SOC 210 acquires the operation ON signal from the EC 120, the SOC 210 activates the OS 2 from the standby state or the stop state, and makes a transition to the normal operation state.

  As described above, the EC 120 detects the remaining capacity of the battery (built-in battery) that supplies power necessary for the processing based on the OS1 and the processing based on the OS2, and activates the OS1 to the normal operation state based on the detected remaining capacity. Limit what is allowed. For example, when the remaining capacity of the battery is small, the EC 120 activates only the OS2 to the normal operation state even when the power switch 20a receives an operation input in the open state.

  Accordingly, when the remaining capacity of the battery is small, the electronic device 10 can suppress the power consumption and prolong the use time of the battery by not activating the OS1 as much as possible.

  Further, in the first embodiment, an example has been described in which the OS 1 is activated to transition to the normal operation state in response to the transition from the closed state to the open state, but the EC 120 determines that the remaining capacity of the battery is equal to or less than a predetermined value. In some cases, the OS 1 may be kept in the standby state or the stopped state even when the OS 1 transitions from the closed state to the open state. In the example of the process illustrated in FIG. 8, when the OS 1 is in the standby state or the stop state in the closed state and only the OS 2 is in the normal operation state, the OS 1 is activated in response to the transition to the open state, and The example in which the state is shifted to the operation state has been described. However, when the remaining capacity of the battery is equal to or less than the predetermined value, the EC 120 determines that the OS1 is in the open state even if the OS2 is in the normal operation state in the closed state. May be kept in a standby state or a stopped state.

(Modification)
As described above, the first and second embodiments of the present invention have been described in detail with reference to the drawings. However, the specific configuration is not limited to the above-described one, and may be set within the scope of the present invention. Various design changes can be made.

  For example, in the above-described embodiment, an example has been described in which the transparent region A covers the second display unit 240 of the main body unit 20 when the cover unit 30 is closed, so that the second display unit 240 becomes visible. Alternatively, a configuration other than that the transparent area A covers the second display unit 240 may be adopted. For example, a configuration may be adopted in which a through hole is provided in a portion of the main body 20 that covers the second display 240 when the cover 30 is closed. In the configuration in which this through-hole is provided, the second display unit 240 can be visually recognized directly (without interposing the transparent area A). Further, in the configuration in which the through holes are provided, it is possible to directly receive a user's operation input to the touch sensor 250. Further, on the back surface of the cover unit 30 (the surface opposite to the surface on which the first display unit is provided), a third display unit capable of displaying in place of the second display unit 240 in the closed state is further provided. Is also good. For example, the third display unit has the same size as the second display unit 240 and is provided at a position overlapping the second display unit 240 in the closed state. The third display unit may be provided at an arbitrary position on the back surface of the cover unit 30. Further, the size of the third display unit may be different from that of the second display unit 240.

  Further, in the above-described embodiment, the configuration example in which the cover unit 30 can be relatively rotated with respect to the main body unit 20 between the closed state and the open state by the hinge 25 has been described. For example, other members (such as a separately added cover) and the main body 20 can be slid with respect to the cover 30 between a position where the first display unit 140 is visible and a position where the first display 140 is not visible. It is good also as a structure.

  In the above-described embodiment, the example in which the power switch 20 is provided on the side surface of the electronic device 10 has been described. However, a light receiving unit that receives an operation signal from a remote controller having the power switch may be provided. That is, the electronic device 10 may include a light receiving unit that receives an operation signal from the remote controller, instead of or in addition to the power switch 20a, as a receiving unit that receives an operation input for causing the OS to transition to the normal operation state.

  Note that the electronic device 10 described above has a computer system inside. Then, a program for realizing the function of each component included in the electronic device 10 described above is recorded on a computer-readable recording medium, and the program recorded on the recording medium is read by a computer system and executed. The processing in each configuration of the electronic device 10 described above may be performed. Here, "to make the computer system read and execute the program recorded in the recording medium" includes installing the program in the computer system. The “computer system” here includes an OS and hardware such as peripheral devices. Further, the “computer system” may include a plurality of computer devices connected via a network including a communication line such as the Internet, a WAN, a LAN, and a dedicated line. The “computer-readable recording medium” refers to a portable medium such as a flexible disk, a magneto-optical disk, a ROM, and a CD-ROM, and a storage device such as a hard disk built in a computer system. Thus, the recording medium storing the program may be a non-transitory recording medium such as a CD-ROM.

  The recording medium also includes an internal or external recording medium accessible from a distribution server for distributing the program. The program may be divided into a plurality of programs, and the programs may be downloaded at different timings and then combined with each other included in the electronic device 10, or the distribution server that distributes each of the divided programs may be different. Further, the “computer-readable recording medium” holds a program for a certain period of time, such as a volatile memory (RAM) in a computer system serving as a server or a client when the program is transmitted via a network. Shall be included. Further, the program may be for realizing a part of the functions described above. Furthermore, what can implement | achieve the function mentioned above in combination with the program already recorded on the computer system, and what is called a difference file (difference program) may be sufficient.

  In addition, some or all of the functions included in the electronic device 10 in the above-described embodiment may be realized as an integrated circuit such as an LSI (Large Scale Integration). Each function may be individually formed into a processor, or a part or all may be integrated into a processor. The method of circuit integration is not limited to an LSI, and may be realized by a dedicated circuit or a general-purpose processor. Further, in the case where a technology for forming an integrated circuit that replaces the LSI appears due to the progress of semiconductor technology, an integrated circuit based on the technology may be used.
