Then, the image data is added to the compression / decompression processing unit 226, compressed in accordance with a predetermined compression format (for example, JPEG), and then an image file (for example, Exif) to which predetermined attached information is added, as a media control unit. The data is recorded on the storage medium 230 via 228.

  When the reproduction mode is set, the compressed image data recorded in the storage medium 230 is read out, subjected to a required expansion process by the compression / decompression processing unit 226, and then displayed on the liquid crystal monitor 234 via the display control unit 232. Is output. As a result, the captured image is reproduced and displayed on the liquid crystal monitor 234.

  As described above, the digital camera 200 according to the present embodiment has a function for performing priority setting for charging. This setting is performed on the menu screen. That is, in the digital camera 200 according to the present embodiment, an item for setting priority for charging is prepared as one of the items that can be set on the menu screen, and the priority setting for charging can be turned ON / OFF by this item. . When the priority setting for charging is set to ON, the digital camera 200 is charged with priority over other devices (when it is set to OFF, the digital camera 200 is charged in the same order as other devices). The user performs charge priority setting on the menu screen as necessary (OFF in the initial setting).

  In this example, the priority setting for charging is performed on the menu screen, but the method for performing the priority setting for charging is not limited to this. For example, a dedicated setting switch may be provided, and charging priority setting may be turned ON / OFF with this switch.

  The set charging priority setting information (ON / OFF) is recorded in the EEPROM 250 as charging setting information. At the time of charging, the CPU 246 reads information on the priority setting for charging and transmits the information to the charging device 10.

  In this example, the example applied to the digital camera has been described. However, the above-described wireless communication function and the function for performing the charge priority setting are also incorporated in other devices such as a mobile phone, a portable music player, and a PDA. The charging device 10 can be preferentially charged.

<Charging method with charging device>
As described above, the charging device 10 of the present embodiment can be charged by simply placing the device on the charging points 16A to 16I as long as the device has a contactless charging function. A device having a function for performing priority setting for charging can be preferentially charged as necessary. Hereinafter, the charging method by the charging apparatus 10 of this Embodiment is demonstrated.

  FIG. 7 is a flowchart showing the procedure of the charging process in charging device 10 of the present embodiment.

  When the placement detection unit 42 detects that the device to be charged is placed on the stage 14 (step S10), the charging control process is started.

  First, based on the detection result of the placement detection unit 42, it is determined whether or not a plurality of devices to be charged are placed on the stage 14 (step S11).

  When only one device to be charged is placed on the stage 14, charging is started only for that device (step S19). That is, power is supplied only to the primary coil of the charging point where the placement is detected, and charging is started.

  On the other hand, when determining that a plurality of devices to be charged are placed on the stage 14, the CPU 30 tries to communicate with the devices to be charged placed on the stage 14 (step S12). Then, it is determined whether there is a device that can establish communication (step S13).

  As a result of this determination, if there is no device that has established communication, all devices placed on the stage 14 are set as charging targets (step S18), and charging is started (step S19). In this case, the power of the power source is equally allocated to each device and charged (equally supplied to the primary coil of the charging point at which placement is detected). Therefore, the devices placed on the stage 14 are charged with power supplied evenly.

  On the other hand, when determining that there is a device that can establish communication, the CPU 30 attempts to acquire charge setting information from the device that can establish communication (step S14). That is, a request for transmission of charging setting information is made to the device to be charged with which communication has been established.

  The device to be charged transmits its own charging setting information to the charging device 10 in response to the request for transmitting the charging setting information. That is, charging priority setting information (ON / OFF) recorded in a built-in storage unit (EEPROM 250 in the example of the digital camera 200) is read and transmitted to the charging device 10.

  The charging setting information can be acquired only when the charged device side has a transmission function for transmitting the charging setting information (the charged device side has a function for performing priority setting of charging, And only when it can communicate with the charging device 10), in the case of a device without such a function, the charging setting information cannot be acquired. Therefore, in this case, the charge setting information cannot be acquired even if the device to be charged has a communication function. For this reason, when there is no response even after a certain period of time, it is determined that there is no charge setting information.

  CPU30 determines whether there exists any apparatus which charge setting information was acquirable after the transmission request | requirement of such charge setting information (step S15). As a result of this determination, if it is determined that there is no device for which charge setting information has been acquired, the CPU 30 sets all devices mounted on the stage 14 as charging targets (step S18) and starts charging (step S19). ). Also in this case, the power of the power source is equally allocated to all the devices placed on the stage 14 and charged.

  On the other hand, if it is determined that the charge setting information has been acquired, the presence / absence of a device to be preferentially charged (charge priority device) is determined based on the acquired charge setting information (step S16). That is, based on the acquired charging setting information, a device whose charging priority setting is set to ON is detected.

  If it is determined that there is a device whose charge priority setting is ON, that device is set as a charge priority device, and only that device is set as a charge target (step S17). Then, power is supplied only to the primary coil of the charging point where the placement of the charge priority device is detected, and charging is started (step S19).

  When a plurality of charge priority devices are detected, the power of the power source is evenly supplied to all detected charge priority devices and charging is started.

  On the other hand, if the charging setting information has been acquired, but it is determined that there is no device whose charging priority setting is ON (= when all the charging priority settings are OFF), the CPU 30 goes to stage 14 All mounted devices are set as charging targets (step S18), and charging is started (step S19). Therefore, in this case, all the devices placed on the stage 14 are evenly supplied with power and charged.

  As described above, in the charging device 10 according to the present embodiment, when a plurality of devices to be charged are placed on the stage 14, communication is performed with the devices to be charged placed on the stage 14, and acquisition of charging setting information is performed. Will be tried. And if charge setting information is acquired, charge setting (setting to which charging point electric power will be supplied) will be performed based on the acquired information, and charge will be started.

  Thereafter, the CPU 30 determines whether or not charging has been completed for the charged device (step S20). If it is determined that the charging is completed, it is determined whether or not charging of all the devices placed on the stage 14 is completed (step S21).

  As a result of this determination, if it is determined that charging of all the devices has been completed, the CPU 30 ends the charging process. On the other hand, when determining that the charging of all the devices has not been completed, the CPU 30 returns to step S11 and executes the above-described process again.

  Thus, according to charging device 10 of the present embodiment, if priority setting for charging is performed on the charged device side, charging can be performed preferentially according to the setting. Thereby, even if it is a case where a several apparatus is charged at once, according to a user's intention, each apparatus can be charged appropriately.

  Moreover, since the setting to be performed on the charged device side is only the ON / OFF setting, the setting can be easily made without bothering the user.

  In this embodiment, when a plurality of charge priority devices (devices for which charge priority setting is turned on) are detected, the power of the power source is shared between the charge priority devices for charging. However, when a plurality of charge priority devices are detected, the priority order may be automatically assigned based on a predetermined determination criterion, and charging may be performed in order.

  Hereinafter, a method for setting the priority order of charge when a plurality of charge priority devices are detected will be described.

<First method>
In the first method, the operation state of each charge priority device is detected, and the device in operation is preferentially charged.

  FIG. 8 is a flowchart showing a processing procedure when charging is performed by setting the priority order by the first method when a plurality of charge priority devices are detected.

  When the placement detection unit 42 detects that the device to be charged is placed on the stage 14 (step S30), the charging control process is started.

  First, based on the detection result of the placement detection unit 42, it is determined whether or not a plurality of devices to be charged are placed on the stage 14 (step S31).

  When only one device to be charged is placed on the stage 14, charging is started only for that device (step S44). That is, power is supplied only to the primary coil of the charging point where the placement is detected, and charging is started.

  On the other hand, when determining that a plurality of devices to be charged are placed on the stage 14, the CPU 30 tries to communicate with the devices to be charged placed on the stage 14 (step S32). Then, it is determined whether there is a device that can establish communication (step S43).

  As a result of this determination, if there is no device that can establish communication, all devices placed on the stage 14 are set as charging targets (step S39), and charging is started (step S44). In this case, the power of the power source is equally allocated to each device and charged. Therefore, each device mounted on the stage 14 is charged with electric power supplied evenly.

  On the other hand, when determining that there is a device that can establish communication, the CPU 30 attempts to acquire charge setting information from the device that can establish communication (step S34). That is, it requests transmission of charge setting information. In response to the request for transmitting the charge setting information, the device to be charged transmits its own charge setting information to the charging device 10 (only when the device to be charged has a function for transmitting the charge setting information).

  After such a charge setting information transmission request, the CPU 30 determines whether there is a device for which the charge setting information has been acquired (step S35). As a result of this determination, if it is determined that there is no device for which charging setting information has been acquired, the CPU 30 sets all devices mounted on the stage 14 as charging targets (step S39) and starts charging (step S44). ).

  On the other hand, if it is determined that the charge setting information has been acquired, the presence / absence of a charge priority device is determined based on the acquired charge setting information (step S36). That is, based on the acquired charge setting information, a device whose charge priority setting is set to ON is detected and the presence or absence thereof is determined.

  When it is determined that there is no device whose charging priority setting is ON (when it is determined that there is no charging priority device), the CPU 30 sets all the devices placed on the stage 14 as charging targets (steps). S39), charging is started (step S44).

  On the other hand, if it is determined that there is a charge priority device, it is determined whether there is only one charge priority device (step S37).

  If it is determined that there is only one charging priority device, the CPU 30 sets only the detected charging priority device as a charging target (step S38), and starts charging (step S44). That is, power is supplied only to the primary coil of the charging point where the detected charge priority device is placed, and charging is started.

  On the other hand, when determining that there are a plurality of charge priority devices, the CPU 30 executes a process for selecting a charge target.

  FIG. 9 is a flowchart illustrating a procedure of a charging target selection process when a plurality of charging priority devices are detected.

  As shown in the figure, first, the CPU 30 detects the operating state of the charge priority device. That is, it communicates with the charge priority device and requests transmission of information on the operating state (step S40). In response to the operation information transmission request, the charge priority device transmits its operation state information (operating / stopped) to the charging device 10. That is, for example, in the case of a digital camera, when it is moving for image reproduction or data transfer, information on the operation is transmitted, and when no operation is performed, information on the stop is transmitted. To do.

  This operation information is transmitted only when the device to be charged has an operation information transmission function (the function of detecting its own operation state and transmitting the information to the charging device is provided). If the device to be charged does not have a function for transmitting operation information, the operation information cannot be acquired. Therefore, when there is no response to the operation information transmission request, it is determined that there is no state information, and it is determined that the operation is stopped.

  CPU30 determines the presence or absence of the charge priority apparatus in operation based on the acquired status information (step S41). If it is determined that there is a charge priority device in operation, the detected charge priority device in operation is set as a charge target (step S42), and charging is started (step S44). On the other hand, if it determines with there being no charge priority apparatus in operation, all the charge priority apparatuses will be set to charge object (step S43), and charge will be started (step S44).

  In this way, in the present method, when a plurality of charge priority devices are detected, the active charge priority device is preferentially charged.

  As shown in FIG. 8, thereafter, the CPU 30 determines whether or not charging has been completed for the device that has been charged (step S45). If it is determined that the charging is completed, it is determined whether or not charging of all the devices placed on the stage 14 is completed (step S46).

  As a result of this determination, if it is determined that charging of all the devices has been completed, the CPU 30 ends the charging process. On the other hand, if it is determined that charging of all the devices has not been completed, the CPU 30 returns to step S31 and executes the above-described process again.

  Thus, according to charging device 10 of the present embodiment, when a plurality of charging priority devices are detected, the operating device is preferentially charged. Thereby, even when there are a plurality of charge priority devices, the devices can be automatically charged in an appropriate order.

<Second method>
In the first method, when a plurality of charge priority devices are detected, the charge priority devices in operation are preferentially charged. However, when a plurality of charge priority devices in operation are detected, Electric power is evenly distributed and charged.

  In this method, when a plurality of charging priority devices in operation are detected, the priority of charging is further determined according to the operation content. That is, for example, when a device performing data transfer and a device performing image reproduction are detected, the device performing data transfer is preferentially charged.

  The priority order of charging for each operation is defined in advance, and is recorded as a table in the EEPROM 36 of the charging apparatus 10. When a plurality of charge priority devices are detected, the CPU 30 acquires operation information (operation content information) of each charge priority device and refers to the table to determine the charge priority.

  Since processing other than when a plurality of operating priority charging devices are detected is the same as the first method described above, only processing when a plurality of operating priority charging devices are detected will be described.

  FIG. 10 is a flowchart illustrating a procedure of a process for selecting a charging target when a plurality of charging priority devices in operation are detected.

  When a plurality of charge priority devices are detected, first, the CPU 30 detects the operating state of the charge priority device. That is, it communicates with the charge priority device and requests transmission of information on the operating state (step S50). In response to the operation information transmission request, the charging priority device transmits information on its own operation state (in-operation / stopped information, and information on the contents when in operation) to the charging device 10. To do.

  CPU30 determines the presence or absence of the charge priority apparatus in operation based on the obtained state information (step S51).

  If it is determined that there is no charge priority device in operation, the CPU 30 sets all the charge priority devices as charging targets (step S56) and starts charging (step S44).

  On the other hand, when determining that there is a charge priority device in operation, the CPU 30 determines whether or not there are a plurality of charge priority devices in operation (step S52).

  Here, if it is determined that there are not a plurality of operating priority charging devices (when it is determined that there is only one operating priority charging device), the CPU 30 sets the detected operating priority charging devices as charging targets. Setting is performed (step S55), and charging is started (step S44).

  On the other hand, when determining that there are a plurality of charge priority devices in operation, the CPU 30 detects a charge priority device with the highest priority operation (step S53). That is, referring to the table recorded in the EEPROM 36, the charge priority is obtained from the operation contents of each charge priority device, and the obtained priority is compared to detect the charge priority device having the highest priority (mostly). Detects charge priority devices performing high priority operations.) And the charge priority apparatus with the highest detected priority is set as a charge object (step S54), and charge is started (step S44).

  As described above, in the present method, when a plurality of charging priority devices in operation are detected, the priority of charging is further set according to the operation content. Accordingly, even when a plurality of charging priority devices in operation are detected, the devices can be charged in an appropriate order.

<Third method>
The third method detects the battery remaining amount ratio of each individual charge priority device, and preferentially charges devices whose battery remaining amount ratio is equal to or less than a threshold value.

  Compared to the first method, this method is different only in the process for selecting a charging target when a plurality of priority charging devices are detected. Here, the case where a plurality of priority charging devices are detected is described. Only the processing will be described.

  FIG. 11 is a flowchart illustrating a procedure of a charging target selection process when a plurality of charge priority devices are detected.

  If it is determined in step S37 that there is not only one charging priority device (ie, it is determined that there are a plurality of priority charging devices), the CPU 30 acquires information on the remaining battery ratio from each charging priority device (step S60). ). That is, it communicates with each charging priority device, and requests each charging priority device to transmit information on the battery remaining amount ratio. In response to this request, each charging priority device transmits information on its battery remaining capacity ratio to the charging device 10.

  The information on the battery remaining amount ratio is transmitted only when the device to be charged has a battery remaining amount ratio detecting function and a function for transmitting the information. Therefore, information on the battery remaining ratio is not transmitted from a device not equipped with these functions (including no response). In this case, it is processed as no information on the battery remaining amount ratio.

  When the chargeable device side is equipped with a battery remaining amount ratio detection function and its information transmission function, when the charged device is requested to transmit the battery remaining amount information from the charging device 10, The remaining battery ratio of its own battery is detected, and the detected information is transmitted to the charging device 10.

  CPU30 detects the apparatus in which battery remaining ratio exceeds the threshold value based on the information of the remaining battery remaining ratio of each charge priority apparatus acquired.

  The threshold information is recorded in the EEPROM 36, and the CPU 30 compares the threshold recorded in the EEPROM 36 with the acquired battery remaining ratio, and detects a device whose battery remaining ratio exceeds the threshold. To do.

  In addition, it is determined that the threshold value is uniformly exceeded for devices for which information on the remaining battery ratio cannot be obtained (in addition, it may be determined that the threshold value is uniformly equal to or less than the threshold value, or the setting thereof) (In this example, it is determined that the threshold value is uniformly exceeded.)

  Based on the detection result, the CPU 30 determines whether or not all priority charging devices exceed the threshold (step S61). And if it determines with the battery remaining charge ratio of all the priority charge apparatuses exceeding the threshold value, all the priority charge apparatuses will be set to charge object (step S62), and charge will be started (step S44). In this case, all the devices for which charging is preferentially set are charged equally (the power of the power source is supplied equally).

  On the other hand, when determining that there is a device whose battery remaining amount ratio is equal to or less than the threshold value, the CPU 30 sets a device whose battery remaining amount ratio is equal to or less than the threshold value to be charged (step S63), and starts charging (step S44). In this case, only those with a remaining battery ratio equal to or less than the threshold value are charged.

  Thus, in this method, when a plurality of charge priority devices are detected, the remaining battery ratio of the individual charge priority devices is detected, and those below the threshold are preferentially charged. Thereby, even if it is a case where a some apparatus is charged, it can charge in an appropriate order.

<Fourth method>
In the second method, when a plurality of charging priority devices in operation are detected, the priority order is further determined according to the operation content.

  In this method, when a plurality of charge priority devices in operation are detected, information on the remaining battery ratio of each charge priority device is acquired and the battery remaining ratio is equal to or less than the threshold value, as in the third method. Charge with priority.

  Similar to the second method, the first method differs from the first method only in the process for selecting a charge target when a plurality of charge priority devices are detected. Only will be described.

  FIG. 12 is a flowchart illustrating a procedure of a process for selecting a charging target when a plurality of charging priority devices in operation are detected.

  When a plurality of charge priority devices are detected, first, the CPU 30 detects the operating state of the charge priority device. That is, it communicates with the charge priority device and requests the transmission of the operation state information (step S70). In response to the operation information transmission request, the charging priority device transmits information on its own operation state (in-operation / stopped information, and information on the contents when in operation) to the charging device 10. To do.

  CPU30 determines the presence or absence of the charge priority apparatus in operation based on the obtained state information (step S71).

  If it is determined that there is no charge priority device in operation, the CPU 30 sets all the charge priority devices as charging targets (step S78) and starts charging (step S44).

  On the other hand, when determining that there is a charge priority device in operation, the CPU 30 determines whether or not there are a plurality of charge priority devices in operation (step S72).

  If it is determined that there are not a plurality of priority charging devices in operation, the CPU 30 sets the detected priority charging devices in operation as charging targets (step S77), and starts charging (step S44).

  On the other hand, when determining that there are a plurality of charge priority devices in operation, the CPU 30 acquires information on the remaining battery ratio from each charge priority device (step S73). That is, it communicates with each charging priority device, and requests each charging priority device to transmit information on the battery remaining amount ratio. In response to this request, each charging priority device transmits information on its battery remaining capacity ratio to the charging device 10.

  CPU30 detects the apparatus in which battery remaining ratio exceeds the threshold value based on the information of the remaining battery remaining ratio of each charge priority apparatus acquired.

  The threshold information is recorded in the EEPROM 36, and the CPU 30 compares the threshold recorded in the EEPROM 36 with the acquired battery remaining ratio, and detects a device whose battery remaining ratio exceeds the threshold. To do. Then, based on the detection result, it is determined whether or not all the priority charging devices exceed the threshold value (step S74).

  If it is determined that the remaining battery ratio of all the priority charging devices exceeds the threshold value, the CPU 30 sets all the priority charging devices in operation as charging targets (step S75) and starts charging. (Step S44).

  On the other hand, when determining that there is a device whose battery remaining amount ratio is equal to or less than the threshold value, the CPU 30 sets a device whose battery remaining amount ratio is equal to or less than the threshold value to be charged (step S76), and starts charging (step S44). In this case, only those that are in operation and whose battery remaining ratio is equal to or less than the threshold value are charged.

  Thus, in this method, when a plurality of charging priority devices in operation are detected, the remaining battery ratio of each charging priority device is detected, and those below the threshold are preferentially charged. Thereby, even if it is a case where a some apparatus is charged, it can charge in an appropriate order.

<Other methods>
As a method other than the above, set the priority for each type of device to be charged in advance, and if multiple charging priority devices are detected, acquire model information and give priority to the model with higher priority. You may make it charge.

  For example, when a digital camera, a mobile phone, a portable music player, etc. are assumed as the devices to be charged, the charging priority (priority order) is (1) mobile phone, (2) digital camera, (3) mobile phone A music player is set as (4) other device, and when a plurality of charge priority devices are detected, control is performed so that charging is performed in this order.

  In this case, the set priority information is managed as a table and recorded in the ROM or EEPROM.

  A means for setting the priority of charging may be provided so that the user can arbitrarily set it. Thereby, it can charge more appropriately according to a user's will.

  In addition, when a plurality of charge priority devices are detected, information on the last use date and time (for example, information on the last shooting date and time for a digital camera, information on the last call / email date and time for a mobile phone) is displayed. It is also possible to preferentially charge a battery with a new last use date and time (if the last use date information cannot be obtained, the charging order is lowest).

  Alternatively, the placement timing may be detected, and the one with the early or late placement order may be preferentially charged.

  In this embodiment, it is configured to be able to charge a device that does not have a wireless communication function, a charging priority setting function, etc., but only a device that has a wireless communication function, a charging priority setting function, etc. It can also be configured to charge. In this case, the device is always charged based on the information on the priority setting for charging set for each device.

  Further, the processing method when a plurality of charge priority devices are detected may be arbitrarily selected by the user from the processing methods described above.

[Second Embodiment]
In the charging apparatus according to the first embodiment, the device is charged based on the priority setting for charging set by the user. In the charging device according to the present embodiment, the order of charging is determined based on the type of the device to be charged, and the devices are sequentially charged in the determined order.

  Since the basic apparatus configuration is the same as that of the charging apparatus according to the first embodiment described above, only the procedure of the charging process will be described here.

  FIG. 13 is a flowchart illustrating a charging process performed by the charging device according to the second embodiment.

  When the placement detection unit 42 detects that the device to be charged is placed on the stage 14 (step S80), the charging control process is started.

  First, based on the detection result of the placement detection unit 42, it is determined whether or not a plurality of devices to be charged are placed on the stage 14 (step S81).

  When only one device to be charged is placed on the stage 14, the device is set as a charging target and charging is started (step S86). That is, power is supplied only to the primary coil of the charging point where the placement is detected, and charging is started.

  On the other hand, if it is determined that a plurality of devices to be charged are placed on the stage 14, the CPU 30 communicates with the devices to be charged placed on the stage 14 (step S82), and model information (digital camera). , Information on the type of charged device such as a mobile phone) is acquired (step S83).

  In addition, when communication cannot be established, and when model information cannot be acquired even if communication can be established, it is treated as model unknown.

  When the model information (including model unknown information) of each device is acquired, the CPU 30 refers to a predetermined table, and from the obtained model information, the charging order of the devices to be charged placed on the stage 14 Is determined (step S84).

  In this table, charging priority (priority) for each model is recorded and stored in the EEPROM 36. The CPU 30 refers to this table to determine the charging order.

  As an example, it is assumed that the table is recorded with the mobile phone set as the first place, the digital camera as the second place, the portable music player as the third place, and the other devices as the fourth place. In this case, for example, when a mobile phone and a digital camera are placed at each charging point of the stage 14, the charging order is set so that the mobile phone and the digital camera are charged in this order. Further, for example, when a mobile phone, a portable music player, and a PDA (corresponding to another device) are placed on the stage 14, the charging order is set so that the mobile phone, the portable music player, and the PDA are charged in this order. The

  In this way, the CPU 30 determines the charging order according to the type of device placed on the stage 14 (step S84). And it charges in order according to the determined charge order. That is, first, the charging order with the highest charging order (except for those already charged) is selected from the determined charging order (step S85). Then, charging of the selected device is started (step S86). That is, power is supplied to the primary coil of the charging point on which the selected device is placed, and charging is performed.

  Thereafter, the CPU 30 determines whether or not charging of the device that has been charged is completed (step S87). If it is determined that charging is complete, it is determined whether or not charging of all the devices placed on the stage 14 is complete (step S88). If it is determined that charging of all the devices is complete, the CPU 30 Ends the charging process. On the other hand, if it is determined that charging of all the devices has not been completed, the CPU 30 returns to step S81 and executes the above-described processing again.

  Thus, according to the charging device of the present embodiment, when charging a plurality of devices, charging is performed by automatically setting the charging order according to the type of the device to be charged. Thereby, even if it is a case where a several apparatus is charged at once, it can charge appropriately.

  Note that the setting of the priority order of charging for each device may be specified in advance, or may be arbitrarily set by the user. In other words, charging priority setting means may be provided (for example, setting using the screen of the operation panel) so that the user can arbitrarily set and change the charging priority. Thereby, it can charge by reflecting a user's will appropriately.

  In addition, when the same apparatus is detected, you may make it charge simultaneously, and you may make it charge by setting a charging order further in it.

  Further, when setting the power receiving order, for example, the order of placement on the stage may be detected, and charging may be performed in the order of placement.

  Also, communication with the device may be performed to obtain information on the remaining battery ratio, and the charging order may be set in ascending order of the remaining battery ratio (if the remaining battery ratio information cannot be obtained). , Set the charging order to the bottom).

  In the case of a digital camera, communication with the device may be performed to obtain information on the last shooting date and time, and the charging order may be set in order of the last shooting date and time (the information on the last shooting date and time being updated). If you can't get it, set the charging order to the bottom). In addition, information on the free space of the storage medium is obtained by communicating with the device, and the charging order may be set in the order of the free space (if the free space information cannot be obtained, the charging order is lowest). Set).

[Third Embodiment]
The charging device according to the present embodiment is configured as a device for charging a digital camera (including a device having an imaging function. For example, a mobile phone with a camera), and has a free space in a storage medium built in or loaded in each camera. The charging order is automatically determined based on the above, and charging is performed in the determined order.

  Since the basic apparatus configuration is the same as that of the charging apparatus according to the first embodiment described above, only the procedure of the charging process will be described here.

  FIG. 14 is a flowchart illustrating a charging process performed by the charging device according to the third embodiment.

  When the placement detector 42 detects that the camera is placed on the stage 14 (step S90), the charging control process is started.

  First, based on the detection result of the placement detection unit 42, it is determined whether or not a plurality of cameras are placed on the stage 14 (step S91).

  If only one device to be charged is placed on the stage 14, the camera is set as a charging target and charging is started (step S96). That is, power is supplied only to the primary coil of the charging point where the placement is detected, and charging is started.

  On the other hand, if it is determined that a plurality of cameras are placed on the stage 14, the CPU 30 communicates with each camera placed on the stage 14 (step S92), and is loaded or incorporated in each camera. Information on the free capacity of the storage medium is acquired (step S93).

  When communication cannot be established, and when free space information cannot be acquired even if communication can be established, it is treated as no free space.

  When information on the free capacity of each camera (including information on no free capacity) is acquired, the CPU 30 determines the charging order of the cameras placed on the stage 14 so that the batteries are charged in the order of increasing free capacity. (Step S94).

  Thereafter, the CPU 30 selects the one with the highest charging order (excluding the charged camera) among the determined charging orders (step S95), and starts charging the selected camera (step S96). That is, power is supplied to the primary coil of the charging point on which the selected camera is placed, and charging is performed.

  Thereafter, the CPU 30 determines whether or not charging of the charged camera has been completed (step S97). When it is determined that charging has been completed, charging of all the devices mounted on the stage 14 is completed. It is determined whether or not (step S98).

  As a result of this determination, if it is determined that charging of all the devices has been completed, the CPU 30 ends the charging process. On the other hand, if it is determined that charging of all the devices has not been completed, the CPU 30 returns to step S91 and executes the above-described process again.

  When the placement detection unit 42 detects that the camera is placed on the stage 14 (step S100), the charging control process is started.

  First, based on the detection result of the placement detector 42, it is determined whether or not a plurality of cameras are placed on the stage 14 (step S101).

  When only one camera is placed on the stage 14, the camera is set as a charging target, and charging is started (step S106). That is, power is supplied only to the primary coil of the charging point where the placement is detected, and charging is started.

  On the other hand, if it is determined that a plurality of cameras are placed on the stage 14, the CPU 30 communicates with each camera placed on the stage 14 (step S102), and indicates the last shooting date and time of each camera. Information is acquired (step S103).

  It should be noted that if communication cannot be established, and information on the last shooting date / time cannot be acquired even if communication can be established, it is treated as no information.

  When information (including no information) of the last shooting date / time of each camera is acquired, the CPU 30 determines the charging order of each camera placed on the stage 14 so that the last shooting date / time is newly charged. (Step S104). If there is no information, the charging order is automatically set at the lowest level.

  Thereafter, the CPU 30 selects the one with the highest charging order (excluding the charged camera) among the determined charging orders (step S105), and starts charging the selected camera (step S106). That is, power is supplied to the primary coil of the charging point on which the selected camera is placed, and charging is performed.

  Thereafter, the CPU 30 determines whether or not charging of the camera that has been charged is completed (step S107). If it is determined that charging is completed, charging of all the cameras placed on the stage 14 is completed. It is determined whether or not (step S108).

  If it is determined that charging of all the cameras has been completed as a result of this determination, the CPU 30 ends the charging process. On the other hand, if it is determined that charging of all the cameras has not been completed, the CPU 30 returns to step S101 and executes the above-described process again.

  Thus, according to the charging device of the present embodiment, when charging a digital camera, charging is performed in the order of the latest shooting date and time, that is, the date and time of the last shooting. Thereby, even if it is a case where a several digital camera is charged at once, it can charge in an appropriate order. That is, it is possible to preferentially charge a camera that is assumed to be most frequently used.

  In the above example, information on the last shooting date and time is acquired, and the charging order is set in order of the last shooting date and time. The charging order may be set in the order of date and last reproduction date. The user may arbitrarily select the date and time information to be used.

  FIG. 16 is a flowchart illustrating a charging process performed by the charging device according to the fifth embodiment.

  When the placement detection unit 42 detects that the mobile phone is placed on the stage 14 (step S110), the charging control process is started.

  First, based on the detection result of the placement detection unit 42, it is determined whether a plurality of mobile phones are placed on the stage 14 (step S111).

  When only one mobile phone is placed on the stage 14, the mobile phone is set as a charging target and charging is started (step S116). That is, power is supplied only to the primary coil of the charging point where the placement is detected, and charging is started.

  On the other hand, if it is determined that a plurality of mobile phones are placed on the stage 14, the CPU 30 communicates with each mobile phone placed on the stage 14 (step S112), and the final of each mobile phone. Call / mail date and time information is acquired (step S113).

  Here, the last call date / time refers to the date / time at the end of the call when the last call was made using the mobile phone's call function, and the e-mail date / time is the last call using the mobile phone's mail function. This is the date and time when the mail was sent or received.

  If communication cannot be established, and information on the last call / mail date and time cannot be acquired even if communication can be established, it is treated as no information.

  When information on the last call / email date and time (including no information) of each mobile phone is acquired, the CPU 30 stores each mobile phone placed on the stage 14 so that the last shooting date and time is newly charged. A charging order is determined (step S114). If there is no information, the charging order is automatically set at the lowest level.

  Thereafter, the CPU 30 selects the one with the highest charging order (excluding the charged mobile phone) among the determined charging orders (step S115), and starts charging the selected mobile phone (step S116). That is, power is supplied to the primary coil of the charging point on which the selected mobile phone is placed, and charging is performed.

  Thereafter, the CPU 30 determines whether or not charging of the mobile phone that has been charged is completed (step S117), and if it is determined that charging is complete, charging of all the mobile phones mounted on the stage 14 is performed. It is determined whether or not has been completed (step S108).

  As a result of this determination, if it is determined that charging of all mobile phones has been completed, the CPU 30 ends the charging process. On the other hand, if it is determined that charging of all mobile phones has not yet been completed, the CPU 30 returns to step S111 and executes the above-described process again.

  Thus, according to the charging device of the present embodiment, when charging a mobile phone, charging is performed in the order of the last call / mail date and time, that is, the last call or mail. Thereby, even if it is a case where a some mobile phone is charged at once, it can charge in an appropriate order. That is, it is possible to preferentially charge a mobile phone that is assumed to be used most frequently.

  In the above example, the last call / mail date and time information is acquired, and the charging order is set in the order of the last call / mail date and time. However, it has a Web browsing function using the Internet. If there is, information on the last browsing date (access date) may be acquired, and the charging order may be set in the order of the last call / mail / web browsing date.

  Alternatively, information on the last use date and time (date and time when the last operation was performed) may be acquired, and the charging order may be set in order of the last use date and time.

  Further, the user may arbitrarily select the date and time information to be used.

[Sixth Embodiment]
In the charging device of the present embodiment, the charging order is determined based on the last use date and time of the device to be charged, and the devices are charged in order in the determined order.

  Since the basic apparatus configuration is the same as that of the charging apparatus according to the first embodiment described above, only the procedure of the charging process will be described here.

  FIG. 17 is a flowchart illustrating a charging process performed by the charging device according to the sixth embodiment.

  When the placement detection unit 42 detects that the device to be charged is placed on the stage 14 (step S120), the charging control process is started.

  First, based on the detection result of the placement detection unit 42, it is determined whether or not a plurality of devices to be charged are placed on the stage 14 (step S121).

  If only one device to be charged is placed on the stage 14, the device is set as a charging target and charging is started (step S126). That is, power is supplied only to the primary coil of the charging point where the placement is detected, and charging is started.

  On the other hand, when determining that a plurality of devices to be charged are placed on the stage 14, the CPU 30 communicates with the devices to be charged placed on the stage 14 (step S122), and information on the last use date and time. Is acquired (step S123).

  Here, the last use date and time means the date and time when the device to be charged was last used. In the present embodiment, when the device to be charged is a digital camera, the last shooting date / time is the last use date / time, and when the device is a mobile phone, the last call / mail date / time is the last use date / time.

  The information on the final shooting date and time is acquired by using attached information (for example, tag information of an Exif file) of each image file recorded on the storage medium of the digital camera.

  Further, the information on the date / time of the last call / mail is obtained by using the date / time information of the last call / mail managed by the mobile phone.

  In addition, when communication cannot be established, and when information of the last use date and time cannot be acquired even if communication can be established, it is treated as no date and time information.

  When information on the last use date and time of each device (including no date and time information) is acquired, the CPU 30 determines the charging order of the devices to be charged placed on the stage 14 so that the last use date and time are charged in order from the latest. Determine (step S124). Then, the one having the highest charging order (except for those already charged) is selected from the determined charging orders (step S125), and charging of the selected device is started (step S126). That is, power is supplied to the primary coil of the charging point on which the selected device is placed, and charging is performed.

  Thereafter, the CPU 30 determines whether or not charging of the device that has been charged is completed (step S127). If it is determined that charging is complete, it is determined whether or not charging of all devices mounted on the stage 14 is complete (step S128). If it is determined that charging of all devices is complete, the CPU 30 Ends the charging process. On the other hand, if it is determined that charging of all devices has not yet been completed, the CPU 30 returns to step S121 and executes the above-described process again.

  Thus, according to the charging device of the present embodiment, when charging a plurality of devices, the devices are charged by setting the charging order in the order of the last use date and time of the devices to be charged. Thereby, even if it is a case where a several apparatus is charged at once, it can charge in an appropriate order. In other words, since the latest use date and time is assumed to be higher as the date and time of use last, it can be appropriately charged in the order of higher use frequency.

  In the above example, when the device to be charged is a digital camera, the last shooting date is the last use date, but when the function for detecting and managing the last operation date is provided on the digital camera side, The last operation date / time may be the last use date / time.

  Similarly, when the mobile phone is provided with a function for detecting and managing the last operation date and time, the last operation date and time can be set as the last use date and time.

  In addition, when the device to be charged is a portable music player, the last reproduction date / time and operation date / time may be set as the last use date / time.

[Other embodiments]
The charging device of the above embodiment is configured to detect the placement of the device to be charged at each charging point by the weight sensor, but the detection of the placement of the device to be charged at each charging point is limited to this. It is not something.

  In addition, for example, an IC tag (wireless tag) is attached to a device to be charged by the charging device, while an IC tag reader is provided at each charging point, and the IC tag is detected by the IC tag reader, thereby charging each charging point. You may make it detect mounting of an apparatus.

  In this case, various information such as charging setting information, model information, last use date / time information, last shooting date / time information, and last call / mail date / time information is recorded on the IC tag, and the charging setting information, model information, and last use are recorded from the IC tag. Various information such as date / time information, last shooting date / time information, and last call / mail date / time information may be acquired wirelessly. As a result, the placement detection unit and the wireless communication unit can be used together, and the apparatus configuration can be simplified.

  Similarly, by adopting a configuration for detecting placement on a charging point using other proximity wireless communication, it is possible to use both placement detection means and wireless communication means.

  Further, by using infrared communication, it is possible to adopt a configuration in which both the placement detection means and the wireless communication means are used. In other words, each charging point is provided with infrared communication means (infrared communication port), while the infrared communication means is incorporated on the charged device side, and communication with the infrared communication means is established, so that the charged device is placed at the charging point. It is set as the structure which detects. And it is set as the structure which acquires various information using the infrared communication means with which communication was established.
