<Information processing apparatus according to an embodiment of the present invention>
(Constitution)
FIG. 1 shows a system example of an information processing apparatus according to an embodiment of the present invention. In FIG. 1, the information processing apparatus 1 has a wireless communication function such as Bluetooth or wireless LAN, and detects an identifier (ID) of a mobile device such as a mobile phone 2 having the same function. As a result, for example, only when an identifier of a mobile phone owned by a registered user is detected, the operation using the remote controller 3 or the like is enabled. As a result, a third party who does not have a portable device whose ID is registered cannot operate the information processing apparatus 1 such as a personal computer or a hard disk recorder without permission, so that security can be ensured. Here, it is assumed that the mobile device such as the mobile phone 2 is owned by the owner of the information processing apparatus 1.

  Next, the configuration of the information processing apparatus 1 according to the embodiment of the present invention will be described with reference to FIG. The information processing apparatus 1 includes a control unit 16 that controls the overall operation, an operation availability determination unit 11 that is connected to the control unit 16, a mobile phone ID storage unit 12 that records IDs, specifications, and the like of mobile devices such as mobile phones. The main power supply unit 13, the switch unit 14 connected to the control unit 16 and the main power supply unit 13, and the sub power supply unit 19 connected to the other end of the switch unit 14. Further, the information processing apparatus 1 includes a remote control signal receiving unit 15 that communicates with an external remote control 3, a timer unit 17 connected to the control unit 16, and a portable phone such as a mobile phone by a wireless communication function such as Bluetooth or wireless LAN. It has the antenna 19 for communicating with an apparatus, the radio | wireless communication part 20 connected to this, the operation part 21 connected to the control part 16, and the display part 22 which displays operation information etc.

  The information processing apparatus 1 having these configurations performs desired information processing by the operation of the control unit 16 or the like when an operation is received via the remote controller 3 or the operation unit 21. However, in the cellular phone control mode to be described later, a restriction function such as enabling control by the remote control signal receiving unit 15 and the operation unit 21 is given only when a portable device such as an owner's cellular phone is detected within the communication range. .

(Operation in mobile phone control mode)
Next, the operation in the mobile phone control mode including the operation availability determination unit 11, the mobile device ID storage unit 12 and the like will be described in detail using a flowchart.

  First, the control unit 16 determines whether or not the mobile phone control mode is selected by a user operation or the like (S11). That is, the mobile phone control mode can be arbitrarily selected by the user and can be disabled. With the mobile phone control mode selected, for example, a Bluetooth 12-digit address is registered as an identifier (ID) of a plurality of mobile devices as shown in FIG. (S12). Here, validity / invalidity may be set according to each address, and it is also preferable to set a control range.

  Here, the control range refers to a directory of operable data and a function range. For example, in the example of FIG. 5, when A is designated as a control range by the user, both functions of “recording / playback” are possible, and recording processing and playback are performed for free areas and contents of “all directories”. Processing can be performed. When B is designated as the control range by the user, both “recording / playback” functions are possible, and recording processing and playback processing can be performed for the free space and contents of “partial directory”. Similarly, when “C” is selected, the “playback” function becomes possible, and playback processing can be performed on the contents of “all directories”. If it is D, the function of “reproduction” becomes possible, and reproduction processing can be performed on the contents of “partial directory”.

  As shown in the timing chart shown in FIG. 6, the information processing apparatus 1 has a periodic timing such as the timing T <b> 1 by the cooperative operation of the wireless communication unit 20, the operation availability determination unit 11, and the portable device ID storage unit 12. An Inquiry signal is issued, and an identifier (ID) of the portable device stored in the portable device ID storage unit 12 is detected (S13). And if an identifier (ID) is detected (S14), the operation availability judgment part 11 judges whether ID is memorize | stored in the portable apparatus ID memory | storage part 12, and produces | generates a detection signal like timing T2. Then, control is enabled as at timing T4. If the ID cannot be detected in step S14, the timer 17 is turned on to start measuring time (S16).

  After step S16, it is determined whether or not the mobile phone ID can be detected at present (S17). If the mobile phone ID is detected thereafter, the timer 17 is turned off (S18), and the process returns to step S13. Further, if the mobile phone ID is timed out without being detected (S19), the control from the remote controller 2 or the operation unit 21 is disabled by the control of the operation availability determination unit 11 and the control unit 16.

  When the ID is not detected four times continuously for a predetermined time T31 as in the timing T31, for example, it is determined that the mobile phone identifier (ID) is not found for the first time, and the operation control is possible because the operation control is possible. The state is changed to impossible (S20).

Other Embodiments In the information processing apparatus 1 described above, as another embodiment, operation control may be performed without necessarily using the timer 17 as the control operation by the operation availability determination unit 11 and the control unit 16. Is preferred.

  Similarly, as another embodiment, not only the operation is enabled / disabled by the control operation by the operation availability determination unit 11 and the control unit 16, but the mobile phone is not in the area by using the switch unit 14. When a predetermined time elapses, it is preferable to automatically turn off the power. As a result, it is possible to avoid a state in which the power supply of the information processing apparatus 1 is unnecessarily turned on even though the owner is absent.

  Also, as one method of use, even when an owner with a registered ID portable device is near the device, the device can be controlled by turning off the wireless communication unit of the portable device that communicates with the device wirelessly. It can be disabled or the device can be turned off automatically.

  Furthermore, the power saving effect can be expected by performing the control for reducing the power consumption to turn off the power in this way.
