(Hardware configuration of electronic device 100)
First, a hardware configuration of an electronic device 100 to which the present invention can be applied will be described in detail with reference to FIG. FIG. 1 is a block diagram showing a hardware configuration of an electronic device 100 to which the present invention can be applied.

  As shown in FIG. 1, an electronic device 100 to which the present invention can be applied includes a connection detection unit 110, a mode selection unit 120, and a device connection unit 130.

  The electronic device 100 is not particularly limited as long as it is a device to which the additional device 200 can be connected. The electronic device 100 may be, for example, an audio device, a video recording device, a video display device, a digital camera, a mobile phone, a personal computer, a home game machine, various digital home appliances, or other devices.

  The additional device 200 is not particularly limited as long as it is connected to the electronic device 100 and functions. For example, when the electronic device 100 is an audio device, the additional device 200 includes an audio output device such as a speaker or headphones, a video output device such as a liquid crystal display, or a recording medium on which music data is recorded. May be. Further, the additional device 200 may be configured by a device that can visually notify the user of various types of information, such as a display device such as a lamp.

  Further, the additional device 200 may be a device sold together with an electronic device, or may be a device purchased separately. The additional device 200 may be a dedicated product or a general-purpose product. Further, the additional device 200 connected to the electronic device 100 may be one or two or more devices, or may be configured of one or two or more devices.

  The connection detection unit 110 detects whether or not the additional device 200 is connected to the device connection unit 130, and transmits information about whether or not the additional device 200 is connected to the mode selection unit 120 and / or the storage unit 140. For example, the connection detection unit 110 can detect whether or not the additional device 200 is connected to the device connection unit 130 according to a change in voltage in the device connection unit 130.

  Further, the connection detection unit 110 may operate so as to further detect configuration information such as the type and combination of functions of the connected additional device 200. The connection detection unit 110 may operate so as to acquire the configuration information of the additional device through two-way communication between the connection detection unit 110 and the additional device 200.

  The mode selection unit 120 selects whether the electronic device 100 operates in a special operation mode or a standard operation mode. The mode selection unit 120 selects the standard operation mode when the additional device 200 is not connected to the device connection unit 130. The special operation mode may be selected when the device connection unit 130 is connected.

  Here, the “standard operation mode” is a mode set so that the user performs a normal operation for using the electronic device. The “special operation mode” is a mode set to perform an operation other than the standard operation. The special operation mode is, for example, an operation intended to demonstrate the function of an electronic device automatically, a test operation intended to test the performance of the electronic device before shipment, or other special operation. There are modes that are set to perform. The special operation mode may be, for example, a mode in which the electronic device performs an operation such that two or more operations are performed simultaneously or alternately.

  Further, the mode selection unit 120 may change the operation method of the special operation mode according to the type and combination of functions of the additional device. For example, when the electronic device is an audio device and the additional device is a 5.1 channel audio signal compatible speaker, the mode selection unit performs a demonstration operation of outputting a 5.1 channel audio signal to the speaker as a special operation. You can choose. In addition, when the electronic device is an audio device and a microphone and a speaker are connected as additional devices, a demonstration operation that simultaneously performs a music playback function and a sound collection and sound enhancement function can be selected as a special operation. . In this way, it is possible to select a more effective special operation according to the type and combination of the additional devices.

  The device connection unit 130 can connect the additional device 200. The connection method is not particularly limited, and may be either a wired method or a wireless method. For example, if the electronic device 100 is an audio device, the device connection unit 130 may include an audio output terminal and a video output terminal. Further, the electronic device 100 and the additional device 200 may be configured to perform bidirectional communication.

  In the case of a wired system, for example, connection can be made in a commonly used format such as USB (Universal Serial Bus) or IEEE1394. When the additional device is a video display device, for example, the additional device may be connected by a high-definition multimedia interface (HDMI) cable.

  In the case of a wireless system, connection can be made using various communication forms such as infrared communication, visible light communication, RF communication, Bluetooth, IEEE802.11a / b / g.

  The electronic device 100 may further include a storage unit 140 and a command detection unit 150.

  The storage unit 140 includes a semiconductor memory such as an EEPROM (Electronically Erasable and Programmable Read Only Memory). When the command detection unit 150 detects the input of the start command, the storage unit 140 stores that the start command has been input. When the command detection unit 150 detects an input of a cancel command for canceling the special operation mode, the storage unit 140 resets the state in which the start command is input. In addition, the storage unit 140 can provide information on whether a start command is input to the mode selection unit 120. The storage unit 140 may record information other than command input. The storage unit 140 is preferably configured to keep the storage not only when the electronic device is operating but also when the operation is stopped.

  The command detection unit 150 detects an input of a start command that causes the electronic device 100 to operate in the special operation mode, and an input of a release command that cancels the special operation mode of the electronic device 100. Further, the command detection unit 150 transmits a command input to the storage unit 140. The command detection unit 150 can be operated to detect a start command and a release command input from the input unit 160. The command detection unit 150 may operate to detect a start command and a release command that are input by another method that does not depend on the input unit 160. The command detection unit 150 is preferably configured to continue to operate not only when the electronic device is operating, but also when the operation is stopped.

  The electronic device 100 generally includes an arithmetic device and a storage device such as a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), and an EEPROM. The electronic device 100 is configured to operate the connection detection unit 110, the mode selection unit 120, the device connection unit 130, the storage unit 140, the command detection unit 150, the input unit 160, and the like using these arithmetic devices.

  The electronic device 100 may further include an input unit 160.

  The input unit 160 is an input device for inputting a start command for operating the electronic device 100 in the special operation mode and a release command for canceling the special operation mode of the electronic device 100. If the user inputs a command by mistake, the operation in the special operation mode may start against the user's will, so assign an operation that the user does not normally use to the start command and the release command. It is preferable. When the electronic device 100 is an audio device, for example, a start command is input by simultaneously pressing a power button and a playback button for a predetermined time or more, and a cancel command is determined to be input when the same operation is performed. Also good. Further, a dedicated input device may be provided on the back surface of the audio device.

  The electronic device 100 may further include a sub power source 170.

  The sub power source 170 can operate the storage unit 140 and the command detection unit 150 when the external power source 300 and the electronic device 100 are not connected. The sub power supply 170 can be a rechargeable battery, for example. The secondary battery is preferably a rechargeable battery (secondary battery) that can be driven for 12 hours or more, for example.

  If the sub power supply 170 can be driven for 12 hours or more, the storage unit 140 and the command detection unit 150 can be operated so as to adapt to the actual production line and sales of the store. In actual production line and sales operations, the connection between the external power source 300 and the electronic device 100 is released and the electronic device 100 and the additional device 200 are disconnected and shipped or sold within 12 hours. Is almost. Therefore, even after the connection with the external power supply 300 is released, it can be detected that the connection between the additional device 200 and the electronic device 100 is released, so that the special operation mode is automatically performed without inputting the release command. Can be terminated. Therefore, when setting of the special operation mode becomes unnecessary, the electronic device 100 automatically operates in the standard operation mode.

(Example of hardware configuration of audio device)
Next, a hardware configuration example when the electronic apparatus 100 to which the present invention can be applied is an audio device will be described in detail with reference to FIGS.

  In the audio device shown in FIG. 2, the button 162 is an input device for turning on or off the main power, and the button 164 is an input device for starting or pausing music reproduction. In the audio apparatus of FIG. 2, for example, pressing the button 162 and the button 164 simultaneously for a predetermined time or more can be regarded as a command input. For example, if the button 162 and the button 164 are pressed simultaneously for a predetermined time or more, it can be determined that a start command has been input, and it can be determined that a cancel command has been input when the same operation is performed again.

  The configuration example illustrated in FIG. 3A illustrates a state in which stereo speakers 201 and 202 as additional devices are connected to the audio apparatus 101 and the connection is maintained. The configuration example shown in FIG. 3B shows a state in which the stereo speakers 203 and 204 as additional devices and the microphone 205 as an additional device are connected to the audio apparatus 102 and the connection is maintained. The configuration example shown in FIG. 3C shows a state where the stereo speakers 205 and 206 as additional devices and the cartridge 207 as an additional device are connected to the audio apparatus 103 and the connection is maintained. The additional devices are connected to the audio devices in FIGS. 3A to 3C, and the connection state of the additional devices is maintained. Therefore, in the case of these configuration examples, when the start command is input, the mode selection unit can select the special operation mode unless the cancel command is input.

  In the configuration example shown in FIG. 4D, the stereo speakers 208 and 209 which are additional devices are connected to the audio device 204, but the connection is canceled and the additional devices are not connected to the audio device 204. Indicates the state. In the configuration example shown in FIG. 4E, the stereo speakers 210 and 211 as additional devices and the microphone 212 as an additional device are connected to the audio device 205, but the connection of the microphone 212 is released. Indicates the state. In the configuration example shown in FIG. 4F, the stereo speakers 213 and 214 as additional devices and the cartridge 215 as additional devices are connected to the audio device 206, but the connection of the cartridge 215 is released. Indicates the state. In the case of the configuration examples of FIGS. 4D to 4F, since the connection between the audio device and the additional device is released, the mode selection unit automatically ends the operation in the special operation mode and operates in the standard operation mode. Can be selected. In addition, since the audio apparatus having the configuration example shown in FIGS. 4E and 4F maintains connection with some additional devices, the operation method in the special operation mode is used as described above. It may be configured to change.

(Specific example 1 of mode selection operation)
Next, a mode selection operation in a case where the electronic device 100 includes the connection detection unit 110, the mode selection unit 120, and the device connection unit 130 will be described in detail with reference to FIG. FIG. 5 is a flowchart showing the mode selection operation in this case.

  The electronic device operating as shown in FIG. 5 starts processing when the power is turned on (step S10). The mode selection unit selects the standard operation mode if no special operation mode start command is given to the electronic device, and proceeds to the next step if the special operation mode start command is given (step S11). ). Note that the electronic device is usually designed so that a state in which a special operation mode start command is not given is an initial state. Subsequently, the mode selection unit selects the special operation mode when the additional device is connected to the device connection unit, and selects the standard operation mode when the additional device is not connected to the device connection unit (step S12). ).

  In both cases where the special operation mode is selected (step S13) and the standard operation mode is selected (step S14), the mode selection unit returns to a state where the process can be started. That is, the electronic device is configured so that the mode can be changed not only when the power is turned on but also during operation of the electronic device. The processing of the mode selection unit (step S10) during the operation of the electronic device may be set to start when a command is input or when the connection status of the additional device is changed, or may be performed every predetermined time. May be set.

  For example, an electronic device that operates as shown in FIG. 5 is set to operate in a special operation mode, and is turned off while maintaining the connection of the additional device. Even without this, the operation in the special operation mode can be automatically resumed. Also, if you turn on the electronic device and disconnect the additional device while the connection detector is operable, the operation in the special operation mode will automatically end, so you do not have to enter the release command. It can be operated in the standard operation mode.

  Next, a mode selection operation when the electronic device 100 includes the connection detection unit 110, the mode selection unit 120, and the device connection unit 130 and operates as illustrated in FIG. 5 will be described with reference to FIG. FIG. 6 is an explanatory diagram illustrating mode selection when the electronic device 100 includes a connection detection unit 110, a mode selection unit 120, and a device connection unit 130.

  In FIG. 6, the standard operation mode is selected when the start command for the special operation mode is not given to the electronic device, or when the additional device is not connected to the device connection unit. The special operation mode is selected when a special operation mode start command is given to the electronic device and the additional device is connected to the device connection unit. Note that either the determination as to whether or not a special operation mode start command is given and the determination as to whether or not an additional device is connected to the device connection unit may be performed first. From the viewpoint of enabling quick startup of the electronic device, it may be configured to first determine whether or not a special operation mode start command is given.

  5 and 6, when the connection between the additional device and the electronic device is released when the connection detection unit does not operate, the connection detection unit may detect the connection release of the additional device. Since it is not possible, the operation in the special operation mode cannot be automatically terminated. In this case, there is a possibility that the electronic device may reach the user while operating in the special operation mode. In specific example 2a below, a case will be described in which the electronic device further includes a storage unit and a command detection unit so as to eliminate this possibility.

(Specific example 2a of mode selection operation)
Subsequently, in the case where the electronic device 100 further includes a storage unit 140 and a command detection unit 150 in addition to the connection detection unit 110, the mode selection unit 120, and the device connection unit 130 with reference to FIG. The mode selection operation will be described in detail. FIG. 7 is a flowchart showing the mode selection operation in this case.

  When the electronic device operating as shown in FIG. 7 is powered on, the mode selection unit starts processing (step S20). The mode selection unit selects the standard operation mode when the input of the start command is not stored in the storage unit, and selects the special operation mode when the input of the start command is stored in the storage unit (step S21). .

  In any of the cases where the special operation mode is selected in step S21 (step S22) and the standard operation mode is selected (step S23), the mode selection unit returns to a state where the process can be started. Therefore, the electronic device can change the operation mode not only when the power is turned on, but also during the operation of the electronic device.

(Operation of storage unit)
Next, the operation of the storage unit 140 will be described in detail with reference to FIG. FIG. 8 is a flowchart showing the operation of the storage unit.

  When the storage unit starts operating, first, the recording unit enters an initial state in which no input of a start command is recorded, and waits until the command detection unit detects an input of the start command (step S30). When the input of the start command is detected by the command detection unit (step S31), the recording unit records that the start command is input, and waits until the next command is input (step S32). ). Subsequently, when the input of the release command is detected by the command detection unit or the connection detection unit detects that the connection of the additional device is released, the storage unit records the input of the start command. It returns to the state which does not exist (step S33). Thereafter, the storage unit waits until the command detection unit detects an input of a start command (step S30).

  Subsequently, in the case where the electronic device 100 further includes a storage unit 140 and a command detection unit 150 in addition to the connection detection unit 110, the mode selection unit 120, and the device connection unit 130 with reference to FIG. The mode selection operation will be described. FIG. 9 is an explanatory diagram showing mode selection when the electronic device performs mode selection as shown in the flowchart of FIG. 7 and the storage unit operates as shown in the flowchart of FIG.

  In FIG. 9, when the start command for the special operation mode is input and it is not detected that the additional device is disconnected from the device connection unit, the input of the start command is stored in the storage unit. The special operation mode is selected. If the start command for the special operation mode is not input or the connection of the additional device is detected from the device connection unit, the input of the start command is not stored in the storage unit. Selected.

  For example, if the command detection unit is configured to operate even when the main power is not turned on, the electronic device that operates as shown in FIG. 9 can be used as an additional device even when the main power is not turned on. The disconnection can be detected and the input of the start command of the storage unit can be automatically reset. In addition, the storage unit can store and hold the state where the start command is input and the state where the start command is not input even when the main power of the electronic device is turned off. Therefore, even if the electronic device is sold without entering the command to release the special operation mode when the main power of the electronic device is turned off and the special operation mode is released, the electronic device is automatically The standard operation mode will be shifted to the user without any disadvantage.

  On the other hand, when the electronic device operating as shown in FIG. 9 is disconnected from the external power supply and disconnected from the additional device when the connection detection unit is not operating, the storage unit start command Can not be reset. In this case, there is a possibility that the electronic device may reach the user while operating in the special operation mode. Therefore, the electronic device may further include a sub power source so that the connection detection unit can detect the connection release of the additional device even after the connection with the external power source is released. The electronic device configured in this way can detect the disconnection of the additional device even when the external power supply is not connected, and can reset the start command input of the storage unit, thus automatically operating in the special operation mode. Can be terminated automatically.

  Further, if the electronic device that operates as shown in FIG. 9 is configured so that the input of the start command remains semi-permanently in the recording unit, for example, the connection with the additional device is released when the connection detection unit does not operate. If the cancel command is not input, the input of the start command remains in the storage unit. In this case, since the input of the start command remains in the storage unit, there is a possibility that the electronic device may reach the user while operating in the special operation mode. Therefore, the electronic device may be configured so that the input information of the start command stored in the storage unit is automatically reset after a predetermined time has elapsed. Specific Example 2b below describes a case where the storage unit is configured to be automatically reset after a predetermined time has elapsed.

(Specific example 2b of mode selection operation)
Next, a mode selection operation when the storage unit is configured to reset the start command after a predetermined time has elapsed will be described with reference to FIG. FIG. 10 is an explanatory diagram showing mode selection in this case. Note that FIG. 9 and FIG. 10 differ in whether or not the storage unit operates so as to reset the start command after a lapse of a predetermined time, and otherwise operates in the same manner.

  In FIG. 10, when the start command of the special operation mode is input and it is not detected that the additional device is disconnected from the device connection unit, the input of the start command is stored in the storage unit. The special operation mode is selected. If the special operation mode start command has not been input, the disconnection of the additional device has been detected from the device connection unit, or if the predetermined time has elapsed, the input of the start command is stored in the storage unit. Since there is no standard operating mode is selected. Note that the elapse of the predetermined time can be, for example, an elapsed time after the completion of the special operation performed most recently by the electronic device.

  In the electronic device that operates as shown in FIG. 10, for example, the input of the start command is stored in the storage unit, and the connection with the additional device is released when the connection detection unit does not operate, and the release command is input. Even if not, the storage unit is automatically reset when a predetermined time elapses. Therefore, if a predetermined time elapses from the factory or dealer to the user's hand, the start command input in the storage unit is automatically reset, and the electronic device automatically operates in the standard operation mode. Become. Therefore, it is possible to more reliably prevent the user from reaching the user's hand while being set in the special operation mode.

(Control program to which the present invention is applicable)
A control program to which the present invention is applicable can control an electronic device in the same manner as the electronic device according to the present invention. The control program according to the present invention is stored in a storage unit included in the computer, and is read and executed by a CPU included in the computer, thereby causing the computer to function as the information processing apparatus. A computer-readable recording medium in which a computer program is recorded can also be provided.
