  The storage unit 18 is a readable / writable storage device, and includes a related terminal identification information registration area 181, a detection time / related terminal registration area 182, and a setting pattern registration area 183.

  In the related terminal identification information registration area 181, as shown in FIG. 2 (an example of data stored in the related terminal identification information registration area 181), the related terminal and its identification information are registered in advance in association with each other. Yes. The related terminal refers to the external terminal 20 that exists in the vicinity in the user's life pattern, such as a mobile terminal of a family or friend, a home PC (personal computer), a company PC, or the like. The identification information is information for identifying the external terminal 20 and includes, for example, a manufacturing number, a terminal ID, a telephone number, and the like.

  In the detection time / related terminal registration area 182, as shown in FIG. 3 (an example of data stored in the detection time / related terminal registration area 182), related terminals are registered in correspondence with setting patterns and detection times. The setting patterns correspond to user life patterns such as weekdays and holidays, and a plurality of types are registered. The detection time is the time at which the mobile terminal 10 detects the identification information of the external terminal 20 existing in the vicinity. In FIG. 3, for example, the detection time is set every hour from 0:00. The related terminal registered for the detection time means the external terminal 20 that should be present in the vicinity of the user (within the short-range wireless communication range of the mobile terminal 10) at the detection time. For example, in the case of setting pattern 1, since the user is sleeping at home at the detection time of 0:00 am, 1:00 am, 2 pm, 3 pm, 4 pm, 5 pm, and 6 pm The PC is registered. In addition, at the time of detection at 7:00 am and 8:00 am, since the user commute by car, the car car navigator of the car is registered. There may be one or more related terminals. It is desirable to register a plurality of possible external terminals 20 at a detection time that cannot be narrowed down to one external terminal 20. Further, as in setting pattern 3, it is also possible to register all related terminals for all detection times.

  In the setting pattern registration area 183, as shown in FIG. 4 (an example of data stored in the setting pattern registration area 183), which setting pattern is currently applied is registered.

  Next, the operation of the embodiment of the present invention will be described with reference to FIGS. FIG. 5 is a flowchart showing the operation of the embodiment of the present invention.

  Referring to FIG. 5, first, as a preliminary preparation, the user registers in advance identification information of related terminals. Specifically, the user activates the lock registration function provided in the mobile terminal 10 and requests registration by inputting the related terminal and the identification information from the operation unit 15 on the identification information registration screen displayed on the display unit 16. The control unit 17 stores the input related terminal and identification information in association with each other in the related terminal identification information registration area 181 (see FIG. 2) (step A1). Next, the user inputs the detection time and the related terminal corresponding to the detection time from the operation unit 15 on the related terminal registration screen. When there are a plurality of setting patterns, the detected time and the related terminal corresponding to each setting pattern are input. The control unit 17 stores the input information in the detection time / related terminal registration area 182 for each setting pattern (see FIG. 3) and sets the input setting pattern name (setting pattern 1, 2, 3, etc.). Stored in the pattern registration area 183 (step A2). Next, the user selects a setting pattern name (for example, setting pattern 1) to be applied from the operation unit 15 on the setting pattern registration screen. The control unit 17 registers the selected setting pattern 1 as an application pattern (see FIG. 4). This setting pattern is selected as necessary (for example, when changing from a weekday to a holiday or from a holiday to a weekday) (step A3).

  Assuming that the preparations in steps A1 to A3 described above are completed, the operation of the mobile terminal 10 when setting the dial lock will be described.

  The control unit 17 of the mobile terminal 10 refers to the detection time / related terminal registration area 182 periodically (for example, every 10 minutes) to check whether the detection time has come (step A4). When the detection time comes, the control unit 17 acquires identification information of the external terminal 20 existing within the short-range wireless communication range via the short-range wireless communication unit 14 (step A5). If the identification information cannot be acquired in step A5, that is, if the external terminal 20 does not exist within the short-range wireless communication range, the control unit 17 sets the mobile terminal 10 in the dial lock state, Part or all use is restricted (step A6 → step A10).

  When the identification information can be acquired in step A5, the control unit 17 refers to the setting pattern registration area 183 and acquires the currently applied setting pattern (step A6 → step A7). Next, the control unit 17 refers to the detection time / related terminal registration area 182 to acquire the related terminal registered in correspondence with the currently applied setting pattern and detection time, and the acquired identification information of the related terminal Is acquired from the related terminal identification information registration area 181 (step A8). And the control part 17 collates the identification information of the external terminal 20 acquired by step A5, and the identification information of the related terminal acquired by step A8, and discriminate | determines whether it corresponds (step A9). If they match, the control unit 17 does not set the lock and ends the process until the next detection time. If a plurality of related terminals corresponding to the same setting pattern and the same detection time are registered in the detection time / related terminal registration area 182, the lock is set when at least one of the related terminals is detected. Not set (Step A9 → Step A4). If they do not match, that is, if the related terminal registered for the setting pattern and detection time does not exist within the short-range wireless communication range, the control unit 17 sets the mobile terminal 10 in the dial lock state, Limit the use of some or all features. When a plurality of related terminals are registered, the control unit 17 sets the mobile terminal 10 in the dial lock state when all the registered related terminals do not exist within the short-range wireless communication range ( Step A9 → Step A10).

  As described above, in the present embodiment, the external terminal 20 existing in the vicinity is registered for each detection time in consideration of the user's life pattern, and the external terminal 20 registered at each detection time is registered. The dial lock is set when it does not exist in the vicinity. Thereby, since the portable terminal 10 can be automatically locked when the portable terminal 10 is lost or stolen, an effect of preventing unauthorized use of the portable terminal 10 by a third party can be obtained. In the present embodiment, the user only needs to carry the mobile terminal 10, and the above-described effects can be obtained without carrying the unlocking device or the accessory unit described in the background art. ing.

  Further, in the present embodiment, when registering the external terminal 20 at each detection time, a plurality of setting patterns are provided so as to cope with cases where the user's life pattern is different, such as a weekday or a holiday, and the user selects the setting pattern as needed. Like to do. For this reason, the effect that the automatic lock of the portable terminal 10 which followed the user's life pattern finely becomes possible is acquired.

  Next, another embodiment of the present invention will be described.

  In the above-described embodiment, it has been described that the mobile terminal 10 is automatically locked when the related terminal corresponding to the detection time does not exist in the vicinity. That is, it is determined whether or not to lock by one detection at the detection time. On the other hand, in the present embodiment, even if the related terminal cannot be detected at the detection time, the related terminal is continuously detected at a predetermined time interval (for example, every 10 minutes) and continuously for a predetermined number of times (for example, 3 times). The difference is that it locks when it cannot be detected. The configuration of the present embodiment is the same as the configuration of the embodiment (FIG. 1).

  Next, the operation of the present embodiment will be described with reference to FIG. FIG. 6 is a flowchart showing the operation of another embodiment of the present invention.

  Referring to FIG. 6, the operations in steps B1 to B9 are the same as the operations in steps A1 to A9 in FIG. However, in steps A6 and A9 of the embodiment, the dial lock is set in the case of NO, but in steps B6 and B9 of the present embodiment, the process proceeds to step B10 in the case of NO. Yes.

  In step B6, if the control unit 17 of the mobile terminal 10 cannot acquire the identification information of the external terminal 20, that is, if the external terminal 20 does not exist within the short-range wireless communication range, the process proceeds to step B10. In step B9, if the identification information acquired from the external terminal 20 does not match the identification information of the related terminal registered in advance, that is, the related terminal registered in correspondence with the setting pattern and the detection time is short-range wireless. If it does not exist within the communication range, the process proceeds to step B10.

  In step B10, the control unit 17 refers to a clock unit (not shown) and acquires identification information of the external terminal 20 via the short-range wireless communication unit 14 at a predetermined time interval (for example, every 10 minutes).

  When the identification information can be acquired in step B10 (YES in step B11), the control unit 17 refers to the setting pattern registration area 183 and acquires the currently applied setting pattern. Next, the control unit 17 refers to the detection time / related terminal registration area 182 to acquire the related terminal registered in correspondence with the currently applied setting pattern and detection time, and the acquired identification information of the related terminal Is acquired from the related terminal identification information registration area 181. At this time, the acquired related terminal is a related terminal registered in correspondence with the detection time in steps B6 and B9. And the control part 17 collates the identification information of the external terminal 20 acquired by step B10, and the identification information of the registered related terminal, and discriminate | determines whether it corresponds (step B12). If they match, the control unit 17 does not set the lock and ends the process until the next detection time is reached (step B12 → step B4).

  If the identification information could not be acquired in step B10 (NO in step B11), that is, if the external terminal 20 did not exist within the short-range wireless communication range, or if it did not match in step B12, step Proceed to B13. In step B13, the control unit 17 determines whether or not the number of detections at a predetermined time interval (such as a 10 minute interval) has reached a predetermined number (such as 3 times). For example, when the detection in steps B6 and B9 is the detection at the detection time of 13:00 and there is no related terminal, the detection of the external terminal 20 is performed at intervals of 10 minutes of 13:10, 13:20, 13:30. The detection at 13:30 will reach a predetermined number of three times. In step B13, when the predetermined number of times is reached, the control unit 17 sets the mobile terminal 10 in the dial lock state, and restricts the use of some or all of the functions (step B14).

  As described above, in this embodiment, even if the related terminal cannot be detected at the detection time, if it can be detected within a predetermined time (for example, within 30 minutes), the lock is not set and the detection is performed within the predetermined time. The lock was set when it was not possible. As a result, when the user's schedule deviates slightly, for example, when the employee leaves the office a little later than scheduled, the automatic lock is not set. The effect that the lock can be set is obtained.

  Next, application examples and modification examples of the present invention will be described.

However, when automatic unlocking is performed, in addition to a predetermined unlocking operation (such as a password), the identification information match of the external terminal 20 is unlocked. It may be set as a condition. At this time, the control unit 17 stores information indicating whether the lock is based on user operation or automatic lock in a storage area (not shown) of the storage unit 18. In the case of locking by a user operation, the lock is released by a predetermined release operation.

  -In one embodiment mentioned above or other embodiment, although demonstrated that a user inputs identification information from the operation part 15 at the time of registration of identification information of a related terminal, the portable terminal 10 is short-distance wireless from a related terminal. The identification information may be acquired by communication and registered.
