Description

[Technical Field]

[0001] The present invention relates to a measurement device, a control program, and a system. [Background technology]

[0002] In recent years, management of measurement information measured by a biological information measuring device has increasingly been performed using a mobile device connected via short-range wireless communication. The management of measurement information is typically linked to measurement date and time information, and the normal operation of the built-in clock unit of the biological information measuring device is required. Therefore, the biological information measuring device is provided with a user interface for checking the status of the clock unit and setting the date and time information. The status of the clock unit can also be checked and the date and time information can be set from the mobile device. In addition, the biological information measuring device itself may recognize that the date and time information recorded by its own clock unit is inaccurate and perform the necessary processing or transmit the necessary information to correct the date and time on its own or the connected mobile device. On the other hand, there are also users who use a biological information measuring device simply as a device for obtaining current biological information and do not require continuous management of their biological information.

[0003] For example, Patent Document 1 describes a measurement device in which a blood pressure monitor connected to a smartphone via short-range wireless communication generates a packet including information indicating that date and time information is required when the battery is removed, and sends the packet to the smartphone. Patent Document 2 describes a medical device in which a pedometer connected to a step count management device via short-range wireless communication sends a time-set flag to the step count management device indicating whether the time of the built-in clock circuit has been set, and the step count management device, upon receiving the time-set flag, performs a time setting process if the flag is off.

[0028] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment according to one aspect of the present invention will now be described with reference to the accompanying drawings.

[0029] §1 Application Examples <Information management system 100 to which the present invention is applied> FIG. 1 is a diagram showing an example of an information management system 100 including a measuring device 1 of the present invention and an information terminal 5 that communicates wirelessly with the measuring device 1.

[0030] The measuring device 1 includes, for example, a weighing scale, a blood pressure monitor, a body composition monitor, and the like, capable of measuring biological information. The measuring device 1 is a measuring device that is used while placed on the ground or a stand. The measuring device 1 may also include an activity measuring device that measures activity amounts such as the number of steps, walking distance, or calories burned. The activity measuring device is a wearable measuring device that is carried by being attached to the user's body. In contrast to wearable measuring devices, non-wearable measuring devices (such as weighing scales and blood pressure monitors) are called non-wearable measuring devices. The measuring device 1 transmits the measured biological information, activity amounts, and the like to the information terminal 5 via wireless communication as user management measurement information. Note that FIG. 1 shows a blood pressure monitor capable of measuring blood pressure as the measuring device 1. However, the blood pressure monitor cuff and other components are not shown.

[0031] The information terminal 5 stores the management measurement information received from the measurement device 1 in a data storage unit within the information terminal 5. The information terminal 5 is also capable of wireless communication with devices other than the measurement device 1, and stores information acquired from external devices in a data storage unit within the information terminal 5. The information terminal 5 is an information processing device that analyzes various information acquired from the measurement device 1 and other external devices. The information terminal 5 is, for example, a terminal with a display, such as a smartphone, tablet terminal, laptop computer, desktop computer, or wearable terminal. The information terminal 5 may be configured to acquire management measurement information from a specific measurement device 1. The specific measurement device 1 from which the management measurement information is to be acquired may be registered in advance in the data storage unit of the information terminal 5.

[0032] Fig. 2 is a diagram showing an example in which an information terminal 5 is connected to a network. As shown in Fig. 2, the information terminal 5 may be connected to a cloud server 90 via a wide area network N such as the Internet. The information terminal 5 may transmit the management measurement information stored therein to the cloud server 90 via the wide area network N, and the cloud server 90 may manage the user's management measurement information as a database. Furthermore, the information terminal 5 may acquire the management measurement information managed in the cloud server 90 via the wide area network N, and use the acquired management measurement information.

[0033] §2 Configuration example <Configuration of Measuring Device 1> FIG. 3 is a block diagram showing the configuration of the measuring device 1. The measuring device 1 includes a display unit 11 that displays various information, an operation unit 12 operated by the user, a measuring unit 13 that measures biometric information, activity levels, etc., a wireless communication unit 14 that communicates wirelessly with external devices, a timer unit 15 that generates time information, and a sensor 16 that can detect whether the measuring device 1 is stationary or tilted. The measuring device 1 also includes a RAM 17 that temporarily stores information, a data storage unit 18 that stores information and programs, and a controller 19 that controls the overall operation of the measuring device 1. The measuring device 1 also includes a battery box 20 for mounting a battery, an external power supply connection unit 21 for connecting an external power supply, and a power management unit 22 that manages the power status of the battery box 20 and the external power supply connection unit 21. The controller 19 is an example of a "processor" in the present invention.

[0034] Display unit 11 is configured with, for example, a liquid crystal display or an organic EL (Electro Luminescence) display. Operation unit 12 is a user interface that accepts user operations, such as buttons or a touch panel. Buttons include buttons that are physically provided on measurement device 1 and virtual buttons displayed on display unit 11.

[0035] The measurement unit 13 measures biological information such as weight, blood pressure, and body composition, or activity levels such as the number of steps, walking distance, and calories burned. What is measured varies depending on the object being measured by the measurement device 1.

[0036] The wireless communication unit 14 is a communication unit that performs short-range wireless communication, for example, a circuit (module) for performing communication according to the BLE (Bluetooth Low Energy (registered trademark)) standard. The wireless communication unit 14 transmits an advertising signal for performing wireless communication to an unspecified number of external devices via broadcast communication at a predetermined transmission cycle. The wireless communication unit 14 transmits the advertising signal including, for example, the name and attribute information of the measurement device 1, or information about the model. The BLE communication performed by the wireless communication unit 14 is communication that uses, for example, a 2.4 GHz frequency. The wireless communication unit 14 transmits management measurement information, such as biological information or activity levels measured by the measurement unit 13, to, for example, the information terminal 5 via BLE communication.

[0037] The timekeeping unit 15 generates time information to be displayed on the display unit 11 of the measuring device 1, for example. "Time information" includes the current time, such as the current date, day of the week, and time. The timekeeping unit 15 can operate using both a battery and an external power source. The external power source is, for example, an AC (Alternating Current) power source. "Operable using both a battery and an external power source" means that the timekeeping unit 15 can operate with either an external power source or a battery (with remaining power). When both the mains power source and an external power source are present, the timekeeping unit 15 operates using at least one of the external power source and the battery (with remaining power) as its power source (for example, it operates using the external power source). When both the mains power source and an external power source are present, the timekeeping unit 15 may operate using at least one of the external power source and the battery (with remaining power) as its power source while charging the battery (assuming it is a secondary battery) using the external power source. Note that not only the timekeeping unit 15 but the entire measuring device 1 may also be able to operate using both a battery and an external power source. The timekeeping unit 15 becomes unable to keep time when there is no power supply from the battery or the external power source. "Becoming unable to keep time" means that the correct current date and time information cannot be obtained.

[0038] The sensor 16 is, for example, an acceleration sensor or an inclination sensor. The sensor 16 detects when the measuring device 1 (the device itself) comes to a standstill due to the cessation of activity when a user wearing the measuring device 1 stops the activity. The sensor 16 also detects when the measuring device 1 comes to a standstill due to the user removing the measuring device 1 from the user's body and placing it on a desk or the like. The sensor 16 also detects when the measuring device 1 is placed on the ground or a stand, or when it is tilted and held up.

[0039] The RAM 17 is configured by a semiconductor device such as a DRAM or an SRAM, and serves as a working area for the controller 19 as well as temporarily storing information.

[0040] The data storage unit 18 is a recording medium that stores parameters, control programs, management measurement information, etc., required to realize predetermined processing. The data storage unit 18 is configured, for example, by a hard disk drive (HDD) or a semiconductor storage device (SSD).

[0041] Controller 19 performs predetermined processing by executing a control program. In this embodiment, for example, health management application software for the measuring device is pre-installed as a control program in data storage unit 18, and controller 19 performs predetermined processing by executing this health management application software.

[0042] For example, controller 19 associates biological information measured by measurement unit 13 (an example of management measurement information) with time information generated by timer unit 15 and transmits the associated information to information terminal 5 via wireless communication unit 14. Controller 19 also determines whether or not there is battery power supply, and if it determines that there is no battery power supply, transmits notification information indicating that there is no battery power supply to information terminal 5 via wireless communication unit 14. "Whether or not there is battery power supply" refers to whether or not a battery with enough remaining power to operate is attached to measurement device 1. For example, if there is no battery, or if there is a battery but no remaining power, it is determined that there is no battery power supply. Whether or not there is battery power supply is determined based on the voltage measurement results of the power supply line from the battery.

[0043] The notification information is information that causes the information terminal 5 to notify the user that there is no battery power supply. "Notification" refers to notification by the information terminal 5, for example, notification by screen display or audio output. An example message is, "There is no battery in the measuring device main body. (In this case, if you remove the AC adapter, the measurement time may not be recorded correctly.)" The notification information is also information that causes the information terminal 5 to notify the user to insert a battery into the measuring device 1 even when using an external power source. An example message in this case is, "In order to record the measurement time correctly, please insert a battery into the measuring device even when using an AC adapter."

[0044] Furthermore, the controller 19 transmits notification information to the information terminal 5 when a wireless connection with the information terminal 5 is established via the wireless communication unit 14. That is, the controller 19 transmits notification information to the communication partner when a one-to-one wireless connection is established, rather than sending (repeatedly distributing) the notification information as a broadcast signal like an advertising signal. Furthermore, after the wireless connection is established, the controller 19 transmits notification information to the information terminal 5 before transmitting the biological information measured by the measuring device 1 to the information terminal 5. In this case, the notification information is information that causes the information terminal 5 to notify the user that valid time information is not attached to the biological information and to accept a selection by the user as to whether or not to transmit the biological information from the measuring device to the information terminal 5. An example of a message is, for example, "There is no battery in the measuring device itself, so the measurement time may not be recorded correctly. Do you want to transfer the measurement data of the biological information?"

[0045] The battery box 20 is a box into which a battery can be attached or detached. The battery box 20 is electrically connected to a power supply management unit 22. The external power supply connection unit 21 is a portion to which, for example, an AC adapter is connected. The AC adapter may be attachable or detachable to the external power supply connection unit 21. The external power supply connection unit 21 is electrically connected to the power supply management unit 22. The power supply management unit 22 determines whether a battery is attached to the battery box 20 by measuring the voltage of the power supply line from the battery. The power supply management unit 22 also determines whether, for example, an AC adapter is connected to the external power supply connection unit 21 and external power is being supplied by measuring the voltage of the power supply line from the external power source. The power supply management unit 22 outputs the determination result to the controller 19. The power supply management unit 22 also supplies operating voltage to each unit.

[0046] <Configuration of information terminal 5> 4 is a block diagram showing the configuration of the information terminal 5. The information terminal 5 includes a display unit 51 that displays various information, an operation unit 52 that is operated by the user, a first wireless communication unit 53 and a second wireless communication unit 54 that are capable of wireless communication with external devices. The information terminal 5 also includes a RAM 55 that temporarily stores information, a data storage unit 56 that stores information and programs, and a controller 57 that controls the overall operation.

[0047] The display unit 51 is configured with, for example, a liquid crystal display or an organic EL display. The operation unit 52 is a user interface that accepts user operations such as buttons or a touch panel. The buttons include buttons that are physically provided on the information terminal 5 and virtual buttons displayed on the display unit 51.

[0048] The first wireless communication unit 53 is a communication unit that performs cellular communication, such as a circuit (module) for communication in accordance with standards such as 4G, 5G, and LTE (Long Term Evolution: registered trademark). The first wireless communication unit 53 is also a communication unit that performs wireless LAN communication, such as a circuit (module) for communication in accordance with standards such as Wi-Fi (registered trademark). The second wireless communication unit 54 is a communication unit that performs short-range wireless communication, such as a circuit (module) for communication in accordance with the BLE standard.

[0049] The second wireless communication unit 54 acquires management measurement information of the user measured by the measurement device 1, for example, by performing BLE communication with the wireless communication unit 14 of the measurement device 1. The second wireless communication unit 54 receives an advertising signal transmitted from the wireless communication unit 14 of the measurement device 1 by scanning. The second wireless communication unit 54 recognizes the measurement device 1 from the received advertising signal, and transmits a connection request to the measurement device 1 when it desires to establish a communication connection. After transmitting the advertising signal, the measurement device 1 waits for a connection request for a predetermined time, and upon receiving a connection request within the predetermined time, stops transmitting the advertising signal and switches to one-to-one connection communication with the other party of the connection request.

[0050] The RAM 55 is configured by a semiconductor device such as a DRAM or an SRAM, and temporarily stores information and also serves as a working area for the controller 57 .

[0051] The data storage unit 56 is a recording medium that stores parameters necessary to realize predetermined processing, control programs, and management measurement information acquired from the measurement device 1. The data storage unit 56 also stores images of, for example, each model of the measurement device 1 that can be connected to the information terminal 5 via wireless communication, along with their names, attributes, model numbers, etc. The data storage unit 56 is configured, for example, by a hard disk drive (HDD) or a semiconductor storage device (SSD).

[0052] Controller 57 performs predetermined processing by executing a control program. In this embodiment, for example, health management application software for an information terminal is pre-installed as a control program in data storage unit 56, and controller 57 performs predetermined processing by executing this health management application software. For example, when the health management application software for the information terminal is launched, controller 57 controls second wireless communication unit 54 to scan and receive an advertising signal. When controller 57 receives an advertising signal from measurement device 1, controller 57 controls second wireless communication unit 54 to send a connection request to measurement device 1 and acquire management measurement information from measurement device 1.

[0053] §3 Example of operation <First Operation Example of Information Management System 100> 5 is a sequence diagram showing a first operation example of the information management system 100. Assume that a user carrying an information terminal 5 (e.g., a smartphone) is about to measure the user's blood pressure using the measurement device 1 (e.g., a sphygmomanometer). The first operation example is an operation performed when a battery is installed in the measurement device 1 and a valid time is set in the measurement device 1.

[0054] First, the user connects the measurement device 1 to an AC power source (step S11) and turns on the power to the measurement device 1. As described above, the measurement device 1 is in a "battery-equipped" state, and the time is set to valid. In the following explanation, this state is referred to as the valid time period VP (the period indicated by the hatched area).

[0055] The measurement device 1 measures blood pressure based on the user's measurement operation (step S12). The measurement device 1 stores the measured blood pressure measurement data in the data storage unit 18 (step S13). The measurement data stored at this time is data (measurement data (with time)) stored in association with time information held by the measurement device 1.

[0056] The health management application on the information terminal 5 is started by the user.

[0057] The information terminal 5 accepts a connection operation by starting the health management application (step S14). Specifically, the information terminal 5 scans to detect an advertising signal from the measurement device 1, and transmits a connection request signal to the measurement device 1 based on the detected advertising signal. In response, the measurement device 1 receives the connection request and switches to one-to-one connection communication with the information terminal 5. This establishes a wireless connection between the information terminal 5 and the measurement device 1 (step S15). The information terminal 5 transmits time information held by the information terminal 5 to the measurement device 1 (step S16). The time information of the information terminal 5 is accurate time information because it is set based on information from the Internet.

[0058] The measuring device 1 sets the time information stored in the measuring device 1 based on the time information received from the information terminal 5 (step S17). This time setting corrects the discrepancy between the time information stored in the measuring device 1 and the time information received from the information terminal 5 in step S16. Next, the measuring device 1 performs a battery check to determine whether a battery is installed in the measuring device 1 (step S18). The measuring device 1 determines the presence or absence of a battery by measuring the voltage of the power supply line from the battery. In this example, the result of this battery check is "battery present." The measuring device 1 transmits the measurement data (with time) saved in step S13 to the information terminal 5 (step S19). The measuring device 1 may also transmit "battery present" information indicating that a battery is installed along with the measurement data (with time).

[0059] The information terminal 5 stores the measurement data (with time stamp) received from the measurement device 1 in the data storage unit 56 (step S20).

[0060] The user turns off the power to the measurement device 1 and unplugs the AC adapter from the outlet (step S21). Even if the AC adapter is unplugged, the time information of the measurement device 1 is still valid because the battery is still installed.

[0061] If a battery is installed in the measuring device 1, the above-described usage is repeated. The timing of the battery determination (step S18) to determine whether a battery is installed in the measuring device 1 is not limited to immediately before transmitting the measurement data to the information terminal 5. The timing of the battery determination may be, for example, when the measuring device 1 is started up, or may be performed periodically while the measuring device 1 is running. The measuring device 1 may also perform the battery determination after transmitting the measurement data to the information terminal 5, and transmit information indicating the result of the battery determination to the information terminal 5. The measuring device 1 may also delete the measurement data stored in the measuring device 1 after transmitting the measurement data to the information terminal 5.

[0062] <Second Operation Example of Information Management System 100> 6 is a sequence diagram showing a second operation example of the information management system 100. The second operation example is an operation when no battery is installed in the measurement device 1 and a valid time is not set in the measurement device 1.

[0063] First, the user connects the measurement device 1 to an AC power source (step S11) and turns on the power to the measurement device 1. As described above, the measurement device 1 is in a "battery-free" state. Therefore, if the measurement device 1 is connected to an AC power source without a battery, the time on the measurement device 1 will not be valid unless it is reset.

[0064] The measurement device 1 measures blood pressure based on the user's measurement operation (step S12). The measurement device 1 stores the measured blood pressure measurement data in the data storage unit 18 (step S13). The measurement data stored at this time is "time-less" data that is not associated with time information.

[0065] The health management application on the information terminal 5 is started by the user.

[0066] The information terminal 5 accepts a connection operation by starting up a health management application (step S14). The specific connection process is the same as the process described in the first operation example of FIG. 5. This establishes a wireless connection between the information terminal 5 and the measurement device 1 (step S15). The information terminal 5 transmits time information held by the information terminal 5 to the measurement device 1 (step S16). The time information of the information terminal 5 is accurate time information based on information from the Internet.

[0067] The measuring device 1 sets the time information stored in the measuring device 1 based on the time information received from the information terminal 5 (step S17). This time setting enters the time valid period VP (the period indicated by the hatched area) during which the time is valid for the measuring device 1. Next, the measuring device 1 performs a battery check to determine whether a battery is installed in the measuring device 1 (step S18). The measuring device 1 determines the presence or absence of a battery by measuring the voltage of the power supply line from the battery. In this example, the result of this battery check is "no battery." The measuring device 1 transmits the measurement data (no time) saved in step S13 and a no-battery notification indicating that no battery is installed in the measuring device 1 to the information terminal 5 (step S19). The measuring device 1 may transmit the measurement data (no time) and the no-battery notification as a single piece of information or as separate pieces of information.

[0068] The information terminal 5 stores the measurement data (without time) received from the measurement device 1 in the data storage unit 56 (step S20).

[0069] The user turns off the power to the measurement device 1 and unplugs the AC adapter from the outlet (step S21). Because the measurement device 1 in this example does not have a battery, unplugging the AC adapter means that the time information of the measurement device 1 set in step S17 is no longer valid (the time information is lost).

[0070] The information terminal 5 displays on the display unit 51 a notification screen informing the user that no battery is installed in the measuring device 1 (step S22).

[0071] If no battery is installed in the measuring device 1, the above-described usage is repeated. Note that in the above example, the measuring device 1 transmits measurement data without a time stamp (no time) to the information terminal 5 (step S19), but this is not limited to this. For example, the measuring device 1 may transmit to the information terminal 5 a false time (e.g., 99:99) that can be determined to be invalid as the time information attached to the measurement data.

[0072] <Example of notification screen displayed on information terminal 5> Fig. 7 is a diagram showing a first notification screen 61 displayed on the information terminal 5 in the second operation example of Fig. 6. The first notification screen 61 is a screen that notifies the user that there is no battery power supply to the measurement device 1. The first notification screen 61 is displayed on the display unit 51, for example, in step S22 of Fig. 6.

[0073] 7, a message 62 such as "There is no battery in the device main body" is displayed on the first notification screen 61. Also, a device image 63 showing the target measurement device (for example, a blood pressure monitor) is displayed on the first notification screen 61.

[0074] Fig. 8 is a diagram showing a second notification screen 64 displayed on information terminal 5 in the second operation example of Fig. 6. Second notification screen 64 is a screen that prompts the user to insert a battery into measuring device 1 even when an external power source is used for measuring device 1. Second notification screen 64 is displayed on display unit 51, for example, in step S22 of Fig. 6.

[0075] 8, the second notification screen 64 displays a message 65 such as "There are no batteries in the device. To correctly record the measurement time, please insert batteries even when using an AC adapter." Also, the second notification screen 64 displays a device image 63 showing the target measurement device (for example, a blood pressure monitor).

[0076] As described above, measurement device 1 can operate using a removable battery and an external power source, and transmits measurement data and time information in association with each other to information terminal 5. It then determines whether or not there is battery power supply, and if it determines that there is no battery power supply, it transmits notification information indicating that there is no battery power supply to the information terminal. With this configuration, by transmitting notification information indicating that there is no battery power supply to information terminal 5, it is possible to prompt the user carrying information terminal 5 to insert a battery into measurement device 1. This allows the user to take action (insert a battery) based on the notification information to record correct measurement information for the measurement data.

[0077] Furthermore, the measurement device 1 transmits notification information to the information terminal 5 in a state where a one-to-one wireless connection between the measurement device 1 and the information terminal 5 is established. With this configuration, the communication resources required by the measurement device 1 can be reduced in wireless communication between the measurement device 1 and the information terminal 5, compared to when communication is performed using a broadcast signal such as an advertising signal.

[0078] <Third Operation Example of Information Management System 100> 9 is a sequence diagram showing a third operation example of the information management system 100. The third operation example is similar to the second operation example described above in that there is no battery in the measuring device 1 and no valid time is set in the measuring device 1, but differs from the second operation example in that the measurement data is transmitted after first notifying that there is no battery. "No battery" also includes the case where there is no remaining battery power (the remaining power is so low that data cannot be measured).

[0079] As shown in FIG. 9, the operations from step S11 to step S18 are the same as the operations from step S11 to step S18 of the second operation example shown in FIG.

[0080] When the measuring device 1 determines that there is no battery in the battery determination (step S18) to determine whether there is a battery in the measuring device 1, it first transmits information that there is no battery to the information terminal 5, notifying that there is no battery in the measuring device 1 (step S19).

[0081] When the information terminal 5 receives a notification from the measurement device 1 that there is no battery, it displays a notification screen on the display unit 51 notifying the user that there is no battery in the measurement device 1 and asking whether or not it is necessary to transfer the data measured by the measurement device 1 to the information terminal 5 (step S20). In response to this notification, the user may perform a selection operation to request the transfer of the measurement data. The information terminal 5 accepts the user's selection of whether or not to transfer the measurement data (step S20). The information terminal 5 sends a transfer request to the measurement device 1 requesting the transfer of the measurement data (step S21).

[0082] In response to a transfer request from the information terminal 5, the measurement device 1 transmits the measurement data (without time) saved in step S13 to the information terminal 5 (step S22). The user turns off the power to the measurement device 1 and unplugs the AC adapter from the outlet (step S23). With the AC adapter unplugged, the time information of the measurement device 1 set in step S17 is no longer valid.

[0083] The information terminal 5 stores the measurement data (without time) received from the measurement device 1 in the data storage unit 56 (step S24).

[0084] In the third operation example when no battery is installed in the measuring device 1, the above-described usage is repeated.

[0085] <Example of notification screen displayed on information terminal 5> Fig. 10 is a diagram showing a third notification screen 66 displayed on the information terminal 5 in the third operation example of Fig. 9. The third notification screen 66 is a screen that notifies the user that valid time information is not attached to the measurement information and whether or not the measurement data needs to be transferred. The third notification screen 66 is displayed on the display unit 51, for example, in step S20 of Fig. 9.

[0086] As shown in FIG. 10, the third notification screen 66 displays a message 67 such as, "Because there is no battery in the device main body, the measurement time may not be recorded correctly. Do you want to transfer the measurement data?" The third notification screen 66 also displays a "Transfer" button 68a to be tapped if the user wishes to transfer the measurement data, and a "Do not transfer" button 68b to be tapped if the user does not wish to transfer the measurement data. The third notification screen 66 also displays a device image 63 indicating the target measurement device (e.g., a blood pressure monitor). When measurement data (without time) is transferred to the information terminal 5, the user may be allowed to manually input the measurement time of the data for that measurement data.

[0087] In this way, the measurement device 1 in the third operation example transmits notification information to the information terminal 5 indicating that there is no battery power supply to the measurement device 1 before transmitting measurement data of biological information to the information terminal 5. With this configuration, it is possible to allow the user to select whether or not they wish to receive measurement data of biological information that is not correctly associated with time information, based on the previously received notification information. This makes it possible to prevent measurement data without attached time information from accumulating in the data storage unit 56.

[0088] §6 Programs The control method of the measuring device 1 described in the above embodiment can be realized by executing a prepared control program on a computer. The control program is recorded on a computer-readable storage medium and executed by being read from the storage medium. The control program may be provided in a form stored on a non-transitory storage medium such as a flash memory, or may be provided via a network such as the Internet.

[0089] Although the embodiments of the present invention have been described in detail above, the above description is merely an example of the present invention in every respect, and various improvements and modifications can be made without departing from the scope of the present invention.
