Description

  The present invention relates to an electronic device, and more particularly to a portable electronic device including two housings.

  Electronic devices such as game machines and PDAs (Personal Digital Assistants) are provided with at least operation keys and a display. In order to reduce the size of the electronic device itself without sacrificing the display size, an electronic device in which an operation key and a display are provided in each of separate housings slidably connected to each other has been put into practical use. In this electronic device, the operation keys provided on the lower housing are exposed by sliding the lower housing with respect to the upper housing from the state where the upper housing and the lower housing are completely overlapped. Thus, the user can operate the operation keys.

  In such a slide-type electronic device, when the upper housing and the lower housing are completely overlapped, the operation key is not exposed to the outside, and the user cannot operate the operation key. Since portable electronic devices are battery-powered, in this case, to reduce power consumption, the operation mode is shifted to the sleep mode and power is supplied to the CPU (Central Processing Unit) that executes the application. It is preferable to stop. However, during the execution of an application that does not basically require key operations, such as a music playback application, even if the operation keys provided on the lower housing are not exposed to the outside, the sleep mode is not entered. In addition, it may be preferable to continue music playback.

  SUMMARY An advantage of some aspects of the invention is that it provides an electronic device in which whether or not to enter a sleep mode can be set by a user operation.

  In order to solve the above problems, an electronic device according to an aspect of the present invention includes an upper housing and a lower housing, and the upper housing and the lower housing are slidably coupled to each other, and the lower housing An electronic device that can take at least two states, that is, an open state in which an operation key provided on the front of the body is exposed to the outside and a closed state in which the operation key is not exposed to the outside, and detects a transition of the state of the electronic device An open / close detection unit for executing an application, a power control unit for setting an operation mode of the application processing unit, and an operation switch operated by a user. The power control unit switches the operation mode of the application processing unit from the normal mode to the sleep mode when the operation switch is in the off state and detects the transition from the open state to the closed state, and the operation switch is turned on. In some cases, even if a transition from the open state to the closed state is detected, the operation mode of the application processing unit is not switched from the normal mode to the sleep mode.

  It should be noted that any combination of the above-described constituent elements and a conversion of the expression of the present invention between a method, an apparatus, a system, a recording medium, a computer program, etc. are also effective as an aspect of the present invention.

  FIG. 1 shows an external configuration of a portable electronic device 10 according to the present embodiment. The electronic device 10 includes an upper housing 20 and a lower housing 30 that are slidably connected. 1A is a front view when the electronic device 10 is in the first state (closed state), and FIG. 1B is a front view when the electronic device 10 is in the second state (open state). FIG. In the closed state of the electronic device 10, the upper housing 20 is almost completely over the lower housing 30, and the operation keys provided on the front surface of the lower housing 30 are not exposed to the outside. When the lower housing 30 is slid with respect to the upper housing 20 from this closed state, the electronic device 10 is in an open state in which operation keys provided on the front surface of the lower housing 30 are exposed to the outside.

  On the front surface of the upper housing 20, a left speaker 21a, a right speaker 21b, operation buttons 22 and a display 23 are provided. Between the back surface of the upper housing 20 and the front surface of the lower housing 30, a slide mechanism (not shown) that slidably connects the upper housing 20 and the lower housing 30 is provided.

  In the open state shown in FIG. 1 (b), direction keys 31a, 31b, 31c, 31d (hereinafter collectively referred to as “direction key 31”) provided on the front surface of the lower housing 30 and an analog pad 32, the microphone 33, the start button 34, the select button 35, and the operation buttons 36a, 36b, 36c, and 36d (hereinafter, collectively referred to as the “operation button 36”) are exposed to the outside. The operation keys such as the direction key 31, the analog pad 32, the start button 34, the select button 35, and the operation button 36 can be operated when the electronic device 10 is opened.

  FIG. 2 shows an external configuration of the electronic device 10. In FIG. 2, the electronic device 10 is in a closed state. 2A is a top view of the electronic device 10, and FIG. 2B is a bottom view of the electronic device 10. A left button 37a, a right button 37b, and volume buttons 38a, 38b are provided on the top surface of the lower housing 30, and a connection terminal 39 and a headphone / microphone terminal 40 are provided on the bottom surface. The connection terminal 39 is used for connecting to an external device.

  FIG. 3 shows an external configuration of the electronic device 10. In FIG. 3, the electronic device 10 is in a closed state. FIG. 3A is a left side view of the electronic device 10, and FIG. 3B is a right side view of the electronic device 10. A media card slot 41 is provided on the left side surface of the lower housing 30, and a hold switch 50 is provided on the right side surface.

  In the electronic device 10, an operation button 22 provided on the front surface of the upper housing 20, a direction key 31 provided on the front surface of the lower housing 30, an analog pad 32, a start button 34, a select button 35, an operation button 36, The left button 37a and the right button 37b provided on the top surface of the lower housing 30 are operation keys operated by the user. The hold switch 50 is moved between the off position and the on position by the user, and when the hold switch 50 is moved to the on position, the acceptance of the operation input to the operation keys by the user is invalidated. When the electronic device 10 is in the closed state, the operation keys provided on the front surface of the lower housing 30 are not exposed to the outside, but the operation buttons 22, the left button 37a, and the right button 37b are always exposed to the outside. . Therefore, when the user ends the use of the electronic device 10, the hold switch 50 is moved to the on position, thereby invalidating the key operation of the operation button 22, the left button 37a, and the right button 37b, and an erroneous operation of the operation key is not intended. Can be avoided.

  The electronic device 10 may be a portable game machine. When used as a game machine, the user opens the electronic device 10 and executes a game application. A game image is displayed on the display 23, and the user can enjoy the game by operating the direction keys 31 and the operation buttons 36 while holding the electronic device 10. When the game is over, the user closes the electronic device 10. Since the electronic device 10 is battery-driven, it is preferable to save power by switching the operation mode from the normal mode to the sleep mode in order to reduce power consumption when the electronic device 10 is closed.

  In recent years, electronic devices have become more multifunctional. For example, music playback functions are increasingly incorporated in electronic devices such as mobile phones. The electronic device 10 of the present embodiment may also be configured to have a music playback function as well as a game execution function. When the electronic device 10 is used as a music playback device, the usage mode is assumed to be different from that of the game machine. That is, when used as a game machine, the user operates the operation key while holding the electronic device 10, but when used as a music playback device, the user does not hold the electronic device 10, It is assumed that the electronic device 10 is put in a bag, a pocket of clothes, etc., and music is listened to using earphones or headphones.

  When used as a music playback device in this way, it is considered that the electronic device 10 is normally closed. However, when the electronic device 10 is closed, the operation mode is always the sleep mode. If it moves to, a music reproduction application will also be complete | finished and it is unpreferable. Therefore, the electronic device 10 according to the present embodiment can set whether or not to enter the sleep mode by a simple switch operation by the user.

  FIG. 4 shows an internal configuration of the electronic device 10. The electronic device 10 includes a main CPU 100 and a system controller 200. The main CPU 100 and the system controller 200 are formed on separate chips, and are each supplied with power from a battery in different systems. The main CPU 100 includes a menu processing unit 102 that generates a menu screen for allowing the user to set main body information and select an application, and an application processing unit 104 that executes an application. The electronic device 10 also includes a setting information holding unit 202 that holds main body information set by the user, and an open / close detection unit 220 that detects a state transition of the electronic device 10.

  The system controller 200 executes various operation key state detection functions, communication processing functions, and power control functions independently of the main CPU 100. Specifically, the system controller 200 includes an operation input reception unit 204, a transition information reception unit 206, a hold state value reception unit 208, a power control unit 210, and a communication processing unit 212.

  The functions of the system controller 200 are realized by a CPU, a memory, a program loaded in the memory, and the like, and here, functional blocks realized by their cooperation are depicted. Accordingly, those skilled in the art will understand that these functional blocks can be realized in various forms by hardware only, software only, or a combination thereof.

  As described above, in the electronic device 10 in the closed state, it is preferable that the operation mode of the main CPU 100 is set to the sleep mode in principle to realize power saving except when a music playback application or the like is being executed. However, some users may wish to display the current time information or the like when the electronic device 10 is in the closed state. Therefore, in the electronic device 10 of the present embodiment, the operation of the electronic device 10 when the electronic device 10 is in the closed state is registered in advance by the user as main body information.

  FIG. 5 shows an example of a screen for setting the operation of the electronic device 10 in the closed state. The menu processing unit 102 generates the setting screen shown in FIG. 5 when the user performs the main body information setting process. When the user presses the operation button 36 b on this setting screen, the operation input receiving unit 204 receives a pressing input of the operation button 36 b and supplies it to the menu processing unit 102. The menu processing unit 102 generates a setting item selection screen prepared for the main body information item “setting when closed”. The setting screen shown in FIG. 5 shows a state in which “standard” is selected as the initial value of the setting item.

  FIG. 6 shows a setting item selection screen 60. The selection screen 60 shows two options of “standard” and “enter sleep mode”. When the setting item “standard” is selected, when the electronic device 10 transitions from the open state to the closed state, the application processing unit 104 executes an application that displays a clock indicating current time information on the display 23. When the setting item “set to sleep mode” is selected, a sleep mode in which power supply to the main CPU 100 is stopped when the electronic device 10 transitions from the open state to the closed state is executed. When the electronic device 10 transitions from the closed state to the open state during execution of the sleep mode, power supply to the main CPU 100 is resumed and the main CPU 100 is resumed. The setting item selected by the user is held in the setting information holding unit 202 as main body information. In the following, a case will be described in which “set to sleep mode” is selected by the user.

  Returning to FIG. 4, in the system controller 200, the transition information receiving unit 206 receives transition information indicating that the electronic device 10 has transitioned from the open state to the closed state or from the closed state to the open state. Accept. The upper housing 20 and the lower housing 30 may be slidably connected by a slide mechanism, and the open / close detection unit 220 may be configured to include a magnetic sensor provided in the slide mechanism. When the electronic device 10 transitions from the open state to the closed state, or when the electronic device 10 transitions from the closed state to the open state, the open / close detection unit 220 outputs transition information indicating the transition to the transition information receiving unit 206. For example, the open / close detection unit 220 outputs the transition information of signal value 0 to the transition information receiving unit 206 when transitioning from the open state to the closed state, and the transition information of signal value 1 when transitioning from the closed state to the open state. Also good. The transition information reception unit 206 receives the transition information from the open / close detection unit 220 and determines whether the electronic device 10 has transitioned to the closed state or the open state.

  Note that the open / close detection unit 220 may output state information indicating whether it is in the open state or the closed state to the transition information receiving unit 206. For example, the open / close detection unit 220 outputs a state value 0 to the transition information receiving unit 206 when in the closed state and a state value 1 when in the open state. At this time, the transition information receiving unit 206 may determine that the state transition has occurred when the state information changes. In this case, the open / close detection unit 220 and the transition information reception unit 206 cooperate to realize a function of detecting a state transition of the electronic device 10.

  The power control unit 210 monitors the transition information received by the transition information receiving unit 206 or the determination result by the transition information receiving unit 206. In the setting information holding unit 202, when the main body information that determines “to enter the sleep mode” is held in the closed state, and the transition from the open state to the closed state is detected, the power control unit 210 In principle, the operation mode of the main CPU 100 is switched from the normal mode to the sleep mode. The normal mode is an operation mode for supplying power to the main CPU 100, and the sleep mode is an operation mode for stopping power supply to the main CPU 100. By setting the operation mode to the sleep mode, power saving can be realized.

  The above is the basic power control of the electronic device 10, but in the electronic device 10 of the present embodiment, the setting information holding unit 202 holds the main body information that defines “to enter the sleep mode” when the electronic device 10 is closed. Control that prohibits the transition to the sleep mode according to the operation state of the operation switch by the user even if the transition from the open state to the closed state is detected without changing the main body information even if it is Is done.

  The hold state value receiving unit 208 receives the state value of the hold switch 50. The state value of the hold switch 50 is a value indicating whether the hold switch 50 is on or off. Note that the state value indicating the ON state is a signal that instructs the operation input receiving unit 204 to disable the reception of the operation input of the operation key. When the hold state value receiving unit 208 receives a state value indicating the ON state of the hold switch 50, the operation input receiving unit 204 invalidates the reception of the operation input of the operation key. This prevents the user from operating the operation keys provided on the electronic device 10 effectively.

  Note that the hold state value receiving unit 208 may receive a signal indicating that the state of the hold switch 50 is switched instead of the state value of the hold switch 50. The hold switch 50 outputs switching information indicating that switching has been performed to the hold state value receiving unit 208 when the user moves the switch from the on position to the off position or from the off position to the on position. When the hold state value receiving unit 208 receives the switching information indicating that the hold switch 50 has been switched from the off state to the on state, the operation input receiving unit 204 invalidates the reception of the operation input of the operation key.

  When the hold switch 50 is in the OFF state, the power control unit 210 detects the transition from the open state to the closed state in the open / close detection unit 220 and / or the transition information reception unit 206, and the operation mode of the main CPU 100 Switch from normal mode to sleep mode. On the other hand, when the hold switch 50 is in the on state, the power control unit 210 does not change the state of the main CPU 100 even if the open / close detection unit 220 and / or the transition information reception unit 206 detects a transition from the open state to the closed state. The normal mode is maintained without switching the operation mode from the normal mode to the sleep mode. Thereby, the application processing unit 104 can continuously execute the application being executed even when the electronic device 10 is in the closed state.

  When the hold switch 50 is in the ON state, the operation input reception unit 204 invalidates the reception of operation input of the operation key. Similarly, the transition information reception unit 206 also outputs the transition information output from the open / close detection unit 220. Disable acceptance of. For this reason, even when the power control unit 210 transitions from the open state to the closed state, the power control unit 210 does not recognize the transition because reception of the transition information is invalidated. Therefore, even when the open / close detection unit 220 and / or the transition information reception unit 206 detects a transition from the open state to the closed state, the power control unit 210 does not recognize the transition, and thus sets the operation mode to the sleep mode. Power control is performed to maintain the normal mode without switching.

  Apart from the process in which the transition information receiving unit 206 described above invalidates the reception of transition information, the power control unit 210 may monitor the state value received by the hold state value receiving unit 208. Even in the case where the setting information holding unit 202 holds the main body information that determines that the sleep mode is set when the setting information holding unit 202 is in the closed state, the power control unit 210 transitions from the open state to the closed state. If the hold switch 50 is in the ON state when the detection is detected, the normal mode may be maintained without switching the operation mode of the main CPU 100 from the normal mode to the sleep mode. Thereby, the application processing unit 104 can continuously execute the application being executed even when the electronic device 10 is in the closed state.

  By assigning the operation mode setting function by the user to the hold switch 50, the resources of the electronic device 10 can be used effectively. In addition, when the electronic device 10 is in the closed state, it is often preferable to invalidate the operation of the operation key. In particular, in a music playback application, the user rarely operates the operation key. Therefore, by assigning an operation mode setting function to the hold switch 50, the operation of the operation key can be invalidated and the transition to the sleep mode can be prohibited by operating the hold switch 50 once. For an application that does not require key operations, a suitable environment can be easily provided.

  As described above, in the electronic apparatus 10 according to the present embodiment, when the power control unit 210 detects the transition from the open state to the closed state when the hold switch 50 is in the on state, the application processing unit 104 is The operation mode of the main CPU 100 is not switched from the normal mode to the sleep mode. As described above, the electronic apparatus 10 according to the present embodiment has an advantage that the user can easily control whether or not the application that has been executed is continued as it is in the closed state by setting the hold switch 50 on and off. is there.

  When the hold switch 50 is in the on state, the main CPU 100 continues to execute the application even in the closed state, but the reception of the operation input of the operation key provided in the electronic device 10 is invalidated. Therefore, a remote controller for operation input may be prepared, and the communication processing unit 212 may accept operation input from the remote controller. As a result, the user can freely operate the music playback application. Whether or not the remote controller can be used may be determined for each application. At this time, even if the hold switch 50 is turned off, the state transition of the electronic device 10 does not occur. Therefore, the power control unit 210 does not switch the operation mode of the main CPU 100 to the sleep mode.

  In the electronic device 10 according to the present embodiment, if the hold switch 50 is in the off state, when the transition is made from the open state to the closed state, the sleep mode is entered. When the electronic device 10 transitions from the closed state to the open state during execution of the sleep mode, power supply to the main CPU 100 is resumed and the main CPU 100 is resumed.

  An operation of the electronic device 10 when the hold switch 50 is moved from the off position to the on position during execution of the sleep mode will be described. If the hold switch 50 is in the on state, the transition information receiving unit 206 invalidates the reception of transition information. For this reason, even when the electronic device 10 transitions from the closed state to the open state, the power control unit 210 does not recognize the transition because reception of transition information is invalidated. Therefore, even if the transition from the closed state to the open state is detected by the open / close detection unit 220 and / or the transition information receiving unit 206, the power control unit 210 does not recognize the transition, so that the operation mode is changed to the normal mode. The main CPU 100 is not resumed without switching.

  FIG. 7 is a flowchart showing the transition control of the main CPU 100 to the sleep mode. As described above, this control flow is based on the premise that main body information that sets the sleep mode when the electronic device 10 is closed is set. The transition information receiving unit 206 monitors arrival of transition information from the open / close detection unit 220 (S10). If the transition information is not output from the opening / closing detection unit 220 (N in S10), this control flow is not executed. When the transition information receiving unit 206 receives transition information indicating that the transition is from the open state to the closed state (Y in S10), depending on whether the hold switch 50 is in the on state or the off state (S12), The transition information receiving unit 206 determines how to handle the transition information.

  If the hold switch 50 is in the off state (N in S12), the transition information reception unit 206 validates the transition information reception, and the power control unit 210 switches the operation mode of the main CPU 100 from the normal mode to the sleep mode ( S16). On the other hand, if the hold switch 50 is in the on state (Y in S12), the transition information receiving unit 206 invalidates the reception of transition information, and the power control unit 210 changes the operation mode of the main CPU 100 from the normal mode to the sleep mode. The normal mode is maintained without switching (S14). Thus, the control of the operation mode of the main CPU 100 ends.

  In the above, this invention was demonstrated based on the Example. This embodiment is an exemplification, and it will be understood by those skilled in the art that various modifications can be made to the combination of each component and each processing process, and such modifications are also within the scope of the present invention. .

  In the embodiment, the power control according to the operation state of the hold switch 50 when the main body information that sets the sleep mode when the electronic device 10 is closed is set. In the modified example, when the main body information is set to enter “standard” when the electronic device 10 is closed, the application processing unit 104 sets the application information according to the operation state of the hold switch 50. Control execution.

  As shown in the embodiment, when the setting item “standard” is selected, when the electronic device 10 transitions from the open state to the closed state, the application processing unit 104 displays a clock indicating the current time information on the display 23. Run the application that you want to display. In the modified example, when the hold switch 50 is in the ON state, even if the electronic device 10 transitions from the open state to the closed state, the transition information reception unit 206 invalidates the reception of the transition information, so that the application processing unit 104 may not execute the application.

  Further, when the electronic device 10 transitions from the open state to the closed state, and the hold switch 50 is turned on while the application processing unit 104 is executing an application for displaying the clock on the display 23, the electronic device 10 Even when the application state transitions from the closed state to the open state, the application processing unit 104 may continue to execute the application. When the transition information receiving unit 206 invalidates the reception of the transition information, the application processing unit 104 does not recognize the transition from the closed state to the open state, and continuously displays the clock on the display 23. At this time, since the hold switch 50 is in the ON state, the key operation of the operation key is invalidated. However, for example, the operation input reception is limited only to the operation key operation necessary for setting the clock, such as time adjustment. The unit 204 may accept it as valid.

  In the embodiment, the hold switch 50 is used as an operation switch for the user to set the operation mode control. However, an operation switch for the user to set the operation mode control may be provided separately from the hold switch 50. .

  Moreover, although the upper housing | casing 20 and the lower housing | casing 30 showed the electronic device 10 connected so that it could slide in a straight advance direction in parallel in the Example, the upper housing | casing 20 and the lower housing | casing 30 are rotating. It may be slidably connected in the direction.
