[0005] In the invention according to claim 1 configured as described above, the master unit and the slave unit can transmit and receive a predetermined space transmission medium to and from each other, and the slave unit signal transmission processing means includes the master unit. When the main unit notifying unit transmits its own identification signal to the main unit signal processing unit, the main unit signal receiving unit changes from a state where the main unit signal reception processing unit is receiving the same identification signal to a state where it is not received. It notifies when the state has changed from a state in which the identification signal has not been received to a state in which the identification signal has been received.

That is, the slave unit and the master unit are initially located at a short distance from each other, and the identification signal transmitted by the slave unit is received by the master unit signal reception processing means. The main unit signal reception processing means cannot receive the same identification signal if it is separated by a distance, and the main unit notifying means notifies the user that the user can move to the place without having an object to which the child unit was previously attached. It becomes clear that he is doing what he has forgotten.

[0007] Further, since the slave unit and the master unit are at a long distance from each other and the identification signal transmitted by the slave unit is not received by the master unit signal reception processing means, the master unit and the slave unit are next determined by a predetermined number. When approaching the distance, the master unit signal reception processing unit receives the identification signal, and the master unit notification unit notifies that the master unit and the slave unit are close to each other. In other words, when a friend holds the parent device and the child device together and waits at a certain place, if this notification is issued, it becomes clear that a person who has been waiting is nearby even in crowded places.

[0008] Furthermore, it becomes clear that there is another person other than yourself who has this carrying item management device,
This notification provides a clue to easily communicate with this other person and provides a place where absolutely others can be friends. Also, when incorporated into a portable game or the like that can be played by a plurality of people, it is possible to search for an opponent or a person playing together with strangers.

[0009] When it is clear from the notification from the master unit that the lost item has been lost as described above, there is a case where it is difficult to know where the lost item to which the slave unit is attached is. As a specific example of a configuration for easily specifying a place where a lost item is located in such a case, the invention according to claim 2 is the portable device management device according to claim 1, wherein the master unit transmits its own identification signal. A slave unit signal transmission processing unit for transmitting, the slave unit receiving the identification signal transmitted from the master unit; and a slave unit signal reception processing unit receiving the identification signal of the slave unit signal reception processing unit.

Upon receiving the identification signal, the slave unit notifying unit notifies according to the identification signal.

That is, the above-mentioned slave unit notifies the place according to the identification signal from the master unit, thereby clarifying the place where the slave unit is located, that is, the place where the forgotten article is lost. Here, in the notification according to the identification signal from the master unit, it is sufficient that the notification is issued from the slave unit when the user wants to be notified. The identification signal may be stopped, and the slave unit may be notified when the identification signal is no longer received. Alternatively, the identification signal from the master unit may be transmitted according to a user's instruction. The notification may be made when the device receives the identification signal.

Further, when the personal belongings management device is used to search for a person who has met as described above, the child device can be notified by an instruction from the parent device. Sometimes it becomes clear whether a meeting person is nearby or not.

In addition, various situations can be considered for the notification, such as a case in which the notification has been made to another person's portable item management device as described above, or a case where a notification command has been issued by the parent device of the own portable item management device. . In such a case, if all are notified with the same sound,
It's hard to tell what's going on.

Therefore, as an example suitable for a user to accurately grasp these situations, the invention according to claim 3 is as follows.

Since the master unit 10 cannot receive the ID from the slave unit 20, the notification mode is set and the notification message is output.

When a predetermined time for outputting a message has elapsed, at time t2, master device 10 enters the encounter mode, and slave device 20 returns to the state of transmitting the pair ID. Master device 10 automatically returns to the forgetting prevention mode when receiving the ID common to the pair again (time t).
3).

When the user presses the operation button of master unit 10 once at time t4, for example, when calling for slave unit 20 from master unit 10 in order to search for a lost item after the forgotten item notification, the master unit 10 applies to the pair. It becomes the notification command mode in which the appropriate ID is transmitted. The slave unit 20 enters the notification mode and outputs a notification message.

When a predetermined time for outputting a message has elapsed, at time t5, base unit 10 enters the encounter mode, and child unit 20 returns to the state of transmitting the pair ID. Master device 10 automatically returns to the forgetting prevention mode when receiving the ID common to the pair again (time t).
6).

If the user tries to leave the place at time t7 while leaving the thing to which the slave unit 20 is attached unattended,
Master device 10 cannot receive the ID common to the pair of the master device and the slave device transmitted from slave device 20, so master device 10 enters the notification mode and outputs a notification message.

When a predetermined time for outputting a message has elapsed, at time t 8, master device 10 enters the encounter mode, and continues to be in the encounter mode as long as no pair ID is received from slave device 20. In other words, in this mode, when a common ID is received from the other parent device to the portable item management device of the present embodiment (time t9), it is notified that another person having this portable item management device is nearby, and again waits for the ID. State.

In the above-described embodiment, the following two types of IDs are used: an ID common to the portable item management device of the present embodiment and an ID common to the pair of the master unit and the slave unit. It is possible to provide notification for each of three different situations: the mode, the notification command mode, and the encounter mode.

That is, the base unit 10 receives the ID common to the portable item management device of the present embodiment, thereby notifying the encounter mode, and the base unit 10 transmits the ID common to the pair of the base unit and the child unit. By not receiving the information, notification of the forgetting prevention mode in the base unit 10 and the notification command mode in the base unit 10 is performed, and the ID common to the pair of the base unit and the slave unit is assigned to the slave unit 2.
By receiving 0, notification of the notification instruction mode in the slave unit is performed.

Here, base unit 10 performs notification by not receiving an ID common to the pair of the base unit and the slave unit, and therefore does not receive the ID because master unit 10 and slave unit 20 are separated. Case and the ID by the notification command from the slave unit 20
The two situations when transmission is stopped are indistinguishable. Therefore, in this case, the notification message for the forgetting prevention and the notification command from the child device 20 to the parent device 10 must be a common message.

Therefore, as a second embodiment, it is possible to transmit the ID for each situation to be notified.
That is, the ID transmitted from the slave to the master at any time is forgotten.
Separately, the search ID is transmitted and received between the parent device and the child device when a notification command is issued. By identifying the reception ID, notification according to the situation can be made.

Further, in the above-described first embodiment, after the child device 20 and the parent device 10 are apart from each other and notify the lost item, the parent device 10 receives the ID common to the pair of the parent device and the child device. Is not normal, and once again the I
The mode has been automatically switched, such as returning to the forgetting prevention mode when D is received, or notifying the encounter mode when receiving the common ID again to the portable item management device of this embodiment. As a third embodiment, this mode switching may be performed by switch control.

In such a case, whether the parent device should notify the user of lost item prevention or the notification of the encounter mode is determined in advance by a user's will by a switch. Even if a common ID is not prepared, the master unit can notify the encounter mode when an ID other than a pair, which is an ID from a slave unit that is not dependent on itself, is received.

That is, in the first embodiment,
If the parent device and the child device were not separated, it did not enter the encounter mode, so that the parent device was an ID from the other parent device to determine the approach of another portable item management device, and was different from the notification command. It is necessary to receive an ID, which is an ID common to the portable item management device of the present embodiment. However, if it is determined by switch control that the mode is the encounter mode, it is possible to enter the encounter mode while the parent device and the child device are close as shown in FIG. Therefore, the ID of the pair of the parent device and the child device that the child device transmits from time to time, and the ID from the parent-child pair used by another user is received to notify the encounter mode. You can make it. In this case, there is no need to prepare a common ID for the portable item management device of the present embodiment, and only one kind of common ID is prepared for the pair of the parent device and the child device.

In the above embodiment, separate control is performed for the master unit and the slave unit. That is, the master unit and the slave unit are different from each other. However, as a fourth embodiment, the master unit and the slave unit may be the same. At this time, the main control of the personal belongings management device is as shown in FIG. 4 and the forgetting prevention mode is as shown in FIG. However, the notification instruction is performed by stopping the ID transmission as shown in FIG.

The operation of the portable item management device configured as described above will be described. FIG. 16 shows the transition of the modes of the portable item management device 1 and the portable item management device 2 in chronological order. The horizontal axis indicates the time axis, and the vertical axis indicates the position in each mode. ing. According to the above flow, the portable item management device of the fourth embodiment is the portable item management devices 1 and 2 to be paired with the ID common to the portable item management device.
Is transmitted and received at any time with a common ID.

When the operation button of the portable item management device 2 is pressed once at time t1 when the portable item management device 1 is called from the portable item management device 2, for example, the ID of the ID common to the pair in the portable item management device 2 is displayed. It becomes the notification command mode in which transmission stops. Since the ID from the portable item management device 2 cannot be received in the portable item management device 1, the portable device management device 1 enters the notification mode and outputs a notification message. Then, when a predetermined time for outputting a message elapses, at time t2, portable item management apparatuses 1 and 2 enter the encounter mode, and upon receiving an ID common to the pair again, automatically return to forget prevention mode (time t3). ).

When the operation button of the portable item management device 1 is pressed once at time t4, for example, when the portable item management device 1 is called from the portable item management device 1, the ID of the ID common to the pair in the portable item management device 1 is displayed. It becomes the notification command mode in which transmission stops. Since the ID from the portable item management device 1 cannot be received in the portable item management device 2, the portable item management device 2 enters the notification mode and outputs a notification message. Then, when a predetermined time for outputting the message has elapsed, the portable device management apparatuses 1 and 2 enter the encounter mode at time 5 and automatically return to the forgetting prevention mode when an ID common to the pair is received again (time 6). ).

When the user tries to leave the place with the portable item management device 1 at time t7 while leaving the thing with the portable item management device 2 attached, the portable item management devices 1 and 2 transmit each other. Since it becomes impossible to receive an ID common to the pair, the portable device management apparatuses 1 and 2 enter the notification mode and output a notification message.

Then, when a predetermined time for outputting the message has elapsed, at time t8, the portable item management device 1
And 2 enter the encounter mode, and remain in the encounter mode as long as the pair ID is not received. In other words, in this mode, when a common ID is received from the other parent device to the portable item management device of the present embodiment (time t9), it is notified that another person having this portable item management device is nearby, and again waits for the ID. State. Further, for the fourth embodiment, as in the second and third embodiments, an ID for each situation may be adopted, or mode switching may be performed by a switch.

As described above, the mode for notifying when the master unit and the slave unit are separated from each other and the mode for notifying when approaching are approached are switched automatically or by the switch, and various situations are determined by the ID. By recording a notification message and making it possible to notify the user with his / her own voice, it is possible to reduce the number of mobile phones, improve convenience, improve entertainment and provide fun usage, and furthermore, The notification sound by the management device can be easily identified.
