Description

  The present invention relates to a technical field for controlling supply of power consumed in an input device such as a mouse.

  In response to increasing awareness of global environmental problems in recent years, the spread of electronic devices including personal computers that operate with less power consumption (hereinafter referred to as “PC (Personal Computer)”) and the like has rapidly increased. It is out. Accordingly, peripheral devices such as a mouse connected to the PC are similarly required to operate with less power consumption. Therefore, there are a wide variety of techniques for reducing power consumption. For example, there are Patent Documents 1 to 3 as related technologies that exist.

  Patent Document 1 discloses a technique related to a wireless mouse device. More specifically, the wireless mouse device includes a power generation coil and a power supply unit that rectifies the power generated by the power generation coil and charges the rectified power. In addition, the wireless mouse device includes a mouse operation control unit that detects movement of the device itself, and a transmission unit that transmits the detected detection signal to the PC main body.

  The power generation coil is configured so that the wireless mouse device slides on the surface of the mouse pad in which a plurality of north poles and south poles are arranged with a predetermined distance. Generate electricity. The power supply unit rectifies the power generated by the power generation coil. And a power supply part charges the rectified electric power. Thereby, the power supply unit can supply power to the mouse operation control unit and the transmission unit.

  The wireless mouse device has a button switch that can move the position of the power generation coil. More specifically, the wireless mouse device can move the position of the power generation coil in one direction in response to, for example, a button switch being pressed. On the other hand, when the wireless mouse apparatus is released from the state where the button switch is pressed, the power generation coil is returned to the original position. By repeating the above-described operation, the power generation coil can generate power in the same manner as the wireless mouse device slides on the surface of the mouse pad.

  Patent Document 2 discloses a technique related to a wireless communication device. The wireless communication device includes a small power generator, a signal generation unit that generates a signal such as a control signal, a communication unit that transmits and receives these signals, and a control unit that controls the signal generation unit and the communication unit.

  More specifically, in the following description, an operation when the wireless communication apparatus is applied to a ball type mouse will be described. The small power generator generates power by utilizing the force that the ball of the ball-type mouse has. In other words, the rotating weight of the small power generator rotates using the force of rotation of the ball. This rotational movement of the rotary weight is transmitted to the magnetized rotor. Thereby, a rotor rotates at high speed. As a result, the power generation coil can generate power.

  When the ball mouse is stationary, the wireless communication device is configured to generate power in response to a switch provided on the ball mouse being pressed. That is, the wireless communication device converts pressure generated by pressing the switch into rotational energy. Thereby, the rotor can be rotated.

  Patent Document 3 discloses a technique related to a power generation device for a wireless mouse. The power generation device includes a power generator, a power storage member that stores power generated by the power generator, and an operation lever that can rotationally drive the power generator. Thereby, a generator can generate electric power, for example by a user pushing an operation lever repeatedly.

  As described above, Patent Documents 1 to 3 disclose techniques that operate using the power generated in the apparatus without using a battery (a primary battery or a secondary battery).

  This wireless mouse communicates with the PC body by wireless communication. That is, it is known that the power consumed by the wireless mouse is larger than the power consumed by the wired mouse. It is also known that a wireless mouse is powered by a battery. Therefore, for example, when sufficient power cannot be supplied due to battery exhaustion (battery has run out), the user needs to replace the battery. For example, when the battery to be replaced cannot be prepared promptly, the user may not be able to operate the PC using the mouse. That is, since the user cannot operate the PC, there is a possibility that the business may be hindered.

  In the techniques disclosed in Patent Documents 1 to 3, it is necessary to repeatedly press the button switch when the mouse is stationary. Or in the said technique, it is necessary to push an operation lever repeatedly. Therefore, the user needs to perform troublesome work of pressing the button switch or pushing the operation lever. As a result, the user cannot operate the PC efficiently. In other words, the deterioration of work efficiency may hinder business.

  In addition, the techniques disclosed in Patent Documents 1 to 3 describe that a wireless mouse is operated using the power generated in the device itself. However, in this technique, there is a possibility that power cannot be supplied when the power that the wireless mouse can operate cannot be generated. That is, the mouse may not be able to operate.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

<First Embodiment>
FIG. 1 is a block diagram showing the configuration of the input device 1 according to the first embodiment of the present invention.

  In FIG. 1, the input device 1 includes a power generation unit 2, a power storage unit 3, a power supply control unit 4, and an input unit 5.

  The power generation unit 2 generates electric power by converting kinetic energy into electric energy. That is, the power generation unit 2 generates kinetic energy generated by operating the input unit 5 (specifically, the input buttons 21 and 22 in FIG. 2 referred to in the second embodiment described later) that can be operated by the user. It generates electricity by converting it into electrical energy. In addition, the power generation unit 2 gives the generated power to the power storage unit 3 (transmits power).

  More specifically, the power generation unit 2 generates power by using, for example, pressure or vibration given from the outside. As an example, the power generation unit 2 may employ a piezoelectric element that generates power by a given pressure or vibration.

  Note that a general technique can be adopted at present as the technique itself for generating electric power by pressure or vibration given by the piezoelectric element. Therefore, detailed description in this embodiment is omitted (hereinafter, the same applies to each embodiment).

  The power storage unit 3 stores the power generated by the power generation unit 2. The power storage unit 3 is discharged by being controlled by a power supply control unit 4 described later. That is, the power storage unit 3 supplies power to the own device (input device 1).

  More specifically, as an example, the power storage unit 3 includes a rectifier circuit that includes a diode bridge that rectifies generated power from alternating current to direct current, and a secondary battery or a capacitor that can store the rectified power. May be adopted. However, the present invention described using this embodiment as an example is not limited to the configuration described above.

  Note that a general technique can be adopted at present as the technique itself for rectifying by the rectifier circuit or for storing the capacitor and the secondary battery. Therefore, detailed description in this embodiment is omitted (hereinafter, the same applies to each embodiment).

  The power supply control unit 4 determines the power storage state in the power storage unit 3. In addition, the power supply control unit 4 supplies power so that the own device can operate, and according to the determination result, the power supply unit 3 and power supply that is another power supply unit different from the power storage unit 3 Controls at least one of the power supplies of the unit 6.

  In the following description, for convenience of description, the description “supplying power so that the own device can operate” is also simply referred to as “supplying power to the own device” (hereinafter referred to as each power supply). The same applies to the embodiment).

  More specifically, the power supply control unit 4 determines whether or not the power necessary for the input device 1 to operate is stored in the power storage unit 3. That is, the power supply control unit 4 determines whether or not the capacity stored in the power storage unit 3 (power storage capacity) has reached a predetermined capacity (first threshold).

  As a result of the determination, when it is determined that the power storage capacity has reached a predetermined capacity, the power supply control unit 4 executes the following processing. That is, the power supply control unit 4 controls the power storage unit 3 so as to supply power to each unit configuring the input device 1. In other words, the power supply control unit 4 controls the power storage unit 3 so as to supply power to the respective units that require power supply.

  On the other hand, when it is determined that the power storage capacity has not reached the predetermined capacity, the power supply control unit 4 executes the following process. That is, the power supply control unit 4 controls the power storage unit 3 and the power supply unit 6 so as to supply power to each unit constituting the input device 1.

  Thus, the input device 1 can supply power from the power storage unit 3 when the power necessary for the operation of the input device 1 is stored in the power storage unit 3. Further, the input device 1 can supply the insufficient power from the power supply unit 6 even when the power supplied from the power storage unit 3 is insufficient. As a result, the input device 1 can operate by using the electric power of the power storage unit 3 and the power supply unit 6 together. Further, the input device 1 can suppress power consumption in the power supply unit 6.

  The control process performed by the power supply control unit 4 will be described later in detail in the second embodiment.

  For example, the input unit 5 inputs a state corresponding to an operation by the user to the own device. The input unit 5 will be described later in detail in the second embodiment.

  As an example, the power supply unit 6 may employ a battery (primary battery or secondary battery) or the like as a power source capable of supplying power to a connected device.

  In the above-described embodiment, as an example, the input device 1 has been described with an example in which the power storage unit 3 and the power supply unit 6 are included. However, the embodiment according to the present invention is not limited to such a configuration. The input device 1 may employ a configuration including one or more power storage units 3 and a power supply unit 6.

  For convenience of explanation, as an example, the input device 1 has been described by taking a configuration including the power supply unit 6 as an example. However, the embodiment according to the present invention is not limited to such a configuration. The input device 1 may adopt a configuration that does not include the power supply unit 6. That is, the input device 1 and the power supply unit 6 may be separate.

  Thus, according to input device 1 concerning this embodiment, while realizing input operation according to operation by a user, and generating electric power, the electric power including the generated electric power is efficiently supplied to an own device. can do. The reason is as described below.

  That is, the input device 1 supplies power to itself according to the power generation unit 2 that generates electric power with the given kinetic energy, the power storage unit 3 that stores the generated power, and the power storage state of the power storage unit 3. This is because it includes a power control unit 4 that controls one or more power sources and an input unit 5 that can input a state according to a user's operation.

<Second Embodiment>
Next, a second embodiment based on the input device 1 according to the first embodiment of the present invention described above will be described. In the following description, the characteristic part according to the present embodiment will be mainly described. At this time, the same reference numerals are assigned to the same configurations as those in the above-described embodiment, and duplicate descriptions are omitted.

  A wireless mouse 10 according to a second embodiment of the present invention will be described with reference to FIGS.

  In the following description, for convenience of explanation, a case where the present invention is applied to a wireless mouse as an input device will be described as an example. This wireless mouse can be communicably connected to the external device using a wireless communication technique between the device and an external device such as a PC (Personal Computer). The wireless mouse is an input device that can input information representing an input operation according to an operation such as a moving direction of the own device to the external device in accordance with an operation by a user.

  FIG. 2 is a block diagram showing a configuration of the wireless mouse 10 according to the second embodiment of the present invention. FIG. 3 is a top view showing the wireless mouse 10 according to the second embodiment of the present invention.

  In FIG. 2, the wireless mouse 10 includes a piezoelectric element 12, a power storage unit 3, a control circuit 14, a primary battery (dry battery) 15, and a power supply control circuit 13 included in the control circuit 14. As shown in FIGS. 2 and 3, the wireless mouse 10 includes an input button 21 that is a first mouse button, an input button 22 that is a second mouse button, and a mouse wheel 23.

  For convenience of explanation, as an example, the wireless mouse 10 will be described with a configuration having two input buttons (input buttons 21 and 22). However, the wireless mouse 10 may employ a configuration having one or more input buttons.

  The piezoelectric element 12 corresponds to the power generation unit 2 described in the first embodiment. The power supply control circuit 13 corresponds to the power supply control unit 4 described in the first embodiment. The input buttons 21 and 22 correspond to the input unit 5 described in the first embodiment. The primary battery 15 corresponds to the power supply unit 6 described in the first embodiment. Therefore, the overlapping description is omitted.

  For example, the control circuit 14 detects the following operation.

The amount of movement of the wireless mouse 10,
The amount of rotation of the mouse wheel 23 and the pressing (clicking) of the input buttons (input buttons 21 and 22).

  The control circuit 14 has a function of sending the detection result to the PC via the communication unit 16, for example. More specifically, for example, the control circuit 14 outputs a state corresponding to a user operation input from the input button as a detection result to the PC.

  The communication unit 16 sends the detection result by the control circuit 14 to, for example, a PC. More specifically, for example, the communication unit 16 may be realized by adopting Bluetooth, which is a short-range wireless communication standard.

  It should be noted that a general technique can be employed at present for the operation of the input buttons (input buttons 21 and 22) and the mouse wheel 23. Therefore, detailed description in this embodiment is omitted.

  FIG. 4 is a cross-sectional view (AA cross-sectional view in FIG. 3) showing the wireless mouse 10 in the second embodiment of the present invention.

  In FIG. 4, the wireless mouse 10 represents a mode in which the piezoelectric element 12 is provided below the input button 22 in the drawing. For convenience of explanation, it is assumed that the piezoelectric element 12 is similarly provided below the input button 21 (not shown).

  More specifically, as an example, the input button has a micro switch on the lower side of the input button that can be turned on or off by being pressed (clicked). Therefore, for example, the piezoelectric element 12 may adopt a configuration provided near the microswitch. Alternatively, the piezoelectric element 12 may be configured to be fixed to the bottom surface (not shown) of the input button.

  Thereby, the piezoelectric element 12 can generate electric power by the kinetic energy generated when the input button is operated (clicked) by the user.

(Description of operation of wireless mouse 10)
In the following description, the operation of the wireless mouse 10 in the present embodiment will be described more specifically.

  FIG. 5 is a flowchart showing an operation performed by the wireless mouse (input device) 10 according to the second embodiment of the present invention. The operation procedure of the wireless mouse 10 will be described along the flowchart.

  In the following description, for convenience of explanation, it is assumed that, as an example, the piezoelectric element 12 generates power using vibration generated when the input buttons (input buttons 21 and 22) are operated by the user. The generated power is stored in the power storage unit 3.

  For convenience of explanation, the above-described configuration will be described as an example. However, the present invention described using this embodiment as an example is not limited to the above-described configuration.

  The power supply control circuit 13 determines the power storage state in the power storage unit 3. That is, the power supply control circuit 13 determines whether or not the storage capacity stored in the storage unit 3 has reached a predetermined capacity (first threshold) (step S1).

  When the power supply control circuit 13 determines that the storage capacity has reached a predetermined capacity, the power control circuit 13 proceeds to step S2 ("YES" in step S1). On the other hand, if the power supply control circuit 13 determines that the storage capacity has not reached the predetermined capacity, the process proceeds to step S4 ("NO" in step S1).

  The power supply control circuit 13 controls the power storage unit 3 to supply power to the own device (step S2). Thereby, the electrical storage part 3 supplies electric power with respect to an own apparatus. More specifically, for example, the power storage unit 3 supplies power to each unit that requires power supply, such as the communication unit 16 and the control circuit 14 constituting the wireless mouse 10 (step S3).

  The power supply control circuit 13 controls the power storage unit 3 and the primary battery 15 to supply power to the communication unit 16 and the control circuit 14 (step S4). Thereby, the electrical storage part 3 and the primary battery 15 supply electric power with respect to the communication part 16 and the control circuit 14 (step S5).

  More specifically, for example, the power supply control circuit 13 includes the power storage unit 3 and the primary battery so as to supply the power required for the operation of the own device among the power supplied from the power storage unit 3 and the primary battery 15. 15 may be adopted.

  Alternatively, for example, the power supply control circuit 13 obtains power that is insufficient when power is supplied from the power storage unit 3 based on the power storage capacity and the power required for the device to operate. In other words, the power supply control circuit 13 calculates (detects) the difference between the storage capacity and the power required for the device to operate.

  The power supply control circuit 13 controls the primary battery 15 so as to supply the insufficient power to each unit constituting the wireless mouse 10 based on the obtained power. Further, the power supply control circuit 13 may be configured to control the power storage unit 3 so as to supply power to the respective units.

  As a result, the wireless mouse 10 supplies power from the primary battery 15 so that the self device can operate even when the power necessary for the self device to operate is not stored in the power storage unit 3. Can do. In addition, the wireless mouse 10 can suppress the consumption of the primary battery 15 as compared to supplying power from only one power source (primary battery 15).

  Here, a configuration example of the power supply control circuit 13 described with reference to FIG. 5 will be described with reference to FIG. FIG. 6 is a diagram illustrating a schematic configuration of the power supply control circuit 13 according to the second embodiment of the present invention. The power supply control circuit 13 includes a comparator 31, a switch circuit 32, and a conversion circuit 33. The switch circuit 32 includes, for example, a switch Q1, a switch Q2, a switch Q3, a NOT (negative) circuit 34, and a NOT circuit 35.

  The comparator 31 compares the storage capacity (output voltage) stored in the storage unit 3 with Vth (voltage threshold: hereinafter referred to as “first threshold”). When the comparator 31 determines that the storage capacity is greater than Vth, the comparator 31 outputs a comparison result (a high signal indicating a high state). On the other hand, when the comparator 31 determines that the storage capacity is smaller than Vth, the comparator 31 outputs a comparison result (low signal indicating a low state).

  More specifically, the switch circuit 32 may be configured by, for example, a field effect transistor (FET). Alternatively, for example, the switch circuit 32 may be realized by partially adopting the technique disclosed in JP-A-2002-116850.

  More specifically, the comparator 31 compares the input voltage Vin2 input from the power storage unit 3 with Vht. The comparator 31 outputs the comparison result.

  In the switch circuit 32, when the comparison result by the comparator 31 is in a high state (that is, Vin2> Vht), the switch Q3 is turned on by a high signal indicating the high state. Thereby, the output voltage Vin <b> 2 of the power storage unit 3 is applied to the conversion circuit 33. The high signal described above is inverted by the NOT circuit 34 and the NOT circuit 35. Therefore, the switch Q1 and the switch Q2 are turned off. At this time, since the switch Q1 is turned OFF, the output voltage Vin1 of the primary battery 15 is not applied to the conversion circuit 33.

  On the other hand, when the comparison result by the comparator 31 is in the low state (that is, Vin2 <Vht), the switch Q3 is turned off by the low signal indicating the low state. The low signal is inverted by the NOT circuit 34 and the NOT circuit 35. Therefore, the switch Q1 and the switch Q2 are turned on. At this time, since the switch Q1 is turned on, the output voltage Vin1 of the primary battery 15 is applied to the conversion circuit 33. Further, since the switch Q2 is turned on, the output voltage Vin2 of the power storage unit 3 is applied to the conversion circuit 33.

  Therefore, the output voltage of the power storage unit 3 and the primary battery 15 is applied to the conversion circuit 33. The conversion circuit 33 converts the power required for the operation of the device itself. The conversion circuit 33 supplies the converted power to the own device.

  In addition, the technique itself which the conversion circuit 33 converts electric power can employ | adopt a general technique now. Therefore, detailed description in this embodiment is omitted.

  The power supply control circuit 13 described above can also be realized by using an arithmetic circuit (not shown) including a CPU (Central_Processing_Unit) that executes a software program (software module). In this case, this software program controls the electronic circuit so that each step of the flowchart shown in FIG. 5 is realized.

  As an example, the power supply control circuit 13 may adopt the configuration for determining the power storage state in the power storage unit 3 described in step S1 when power is supplied from the power storage unit 3 and the primary battery 15 in step S5. Good.

  In this case, when the power supply control circuit 13 determines that the storage capacity stored in the storage unit 3 has reached a predetermined capacity, the power supply control circuit 13 controls the primary battery 15 to stop the supply of power. Further, the power supply control circuit 13 may employ a configuration for controlling the power storage unit 3 so as to supply power to each unit constituting the wireless mouse 10.

  Thereby, even if the wireless mouse 10 is supplying power from the power storage unit 3 and the primary battery 15, if the power necessary for operating the device itself is stored in the power storage unit 3, 3 can supply power. That is, the wireless mouse 10 can select a more optimal power source according to the power storage state in the power storage unit 3. In other words, the wireless mouse 10 can control the power supply so that power can be efficiently supplied to its own device.

  As an example, the power supply control circuit 13 adopts a configuration that executes the following processing when it is determined that there is no power that can be supplied from the power storage unit 3 as a result of determining the power storage state in the power storage unit 3. May be. In other words, the power supply control circuit 13 controls the primary battery 15 so as to supply power to each unit constituting the wireless mouse 10.

  In this case, for example, the power supply control circuit 13 determines whether or not the storage capacity stored in the storage unit 3 has reached the second threshold value. As a result of the determination, if the power supply control circuit 13 determines that the second threshold value has not been reached, a configuration may be adopted in which the primary battery 15 is controlled so as to supply power to each component of the wireless mouse 10. Good. The second threshold can be realized by setting a capacity smaller than the predetermined capacity (first threshold) described above.

  Thereby, even when the wireless mouse 10 is not stored in the power storage unit 3, the wireless mouse 10 can supply power to the own device. The power storage unit 3 can store power over a period in which power is supplied from the primary battery 15.

  In the above-described embodiment, for the sake of convenience of explanation, as an example, the power generation unit 2 has been described using a configuration employing the piezoelectric element 12 as an example. However, the embodiment according to the present invention is not limited to such a configuration.

  For example, the power generation unit 2 may employ a power generation means based on electromagnetic induction disclosed in Patent Document 1. That is, the power generation unit 2 may employ power generation means that generates power by using a mouse pad in which a plurality of N poles and S poles are arranged with a predetermined distance and a power generation coil. For example, the power generation unit 2 may employ a dynamo for power generation (not shown) that converts kinetic energy generated by the rotation of the mouse wheel 23 into electric energy as power generation means. Alternatively, the power generation unit 2 may employ at least one of the power generation methods among the piezoelectric element 12, the power generation means using electromagnetic induction, and the power generation dynamo.

  In the above-described embodiment, for convenience of explanation, the configuration in which the present invention is applied to a wireless mouse is described as an example. However, the embodiment according to the present invention is not limited to such a configuration. For example, the present embodiment according to the present invention may employ a configuration applied to a device that requires power supply, such as a wireless keyboard and a controller used in a home game machine.

  As described above, according to the wireless mouse 10 according to the present embodiment, the effect described in the first embodiment can be enjoyed, and further, control can be performed so that power can be supplied more efficiently.

  This is because the power supply control circuit 13 can execute the following processing even when power is supplied from the primary battery 15. That is, the power supply control circuit 13 controls the power storage unit 3 to supply power from the power storage unit 3 when determining that the power required for the self-device to operate is stored in the power storage unit 3. Because it can. On the other hand, the power supply control circuit 13 can control the primary battery 15 to stop the supply of power.

  Moreover, it is because the power supply control circuit 13 can control the primary battery 15 to supply power from the primary battery 15 when determining that there is no power that can be supplied from the power storage unit 3.

  Although the present invention has been described with reference to the embodiments, the present invention is not limited to the above embodiments. Various changes that can be understood by those skilled in the art can be made to the configuration and details of the present invention within the scope of the present invention.

  The present invention is not limited to the embodiments described above. The present invention is applicable to electronic devices that require power supply, such as various pointing devices, keyboards, controllers used in home game machines, and the like.
