Since it is sufficient that the alarm is transmitted to the traveler M wearing the, the alarm sound may be small or may not be accompanied by the alarm sound such as blinking of a lamp in some cases.

Contrary to the above, the alarm device 17 of the child device 2 is activated when the bag 3 with the child device 2 is stolen or the like, so that the alarm of the child device 2 sounds especially at the time of theft. There is also a great feature in giving up the stolen property. For this reason, it is desirable that the alarm device of the slave unit 2 be activated with a loud alarm sound.

Reference numeral 19 denotes a sensor, for example, an acceleration sensor, which detects when acceleration is applied to the handset 2 such as when the bag 3 with the handset 2 is lifted, and the detection signal is centrally processed. It is for outputting to the unit 15. Further, reference numeral 18 is a power switch for turning on the operation of the slave unit 2, and 20 is a timer. The parent device 1 and the child device 2 having the above configurations are mounted on the traveler M and the bag 3, respectively, as shown in FIG.

Next, a method of using the apparatus and an operating state according to the method of use will be described with reference to FIGS. 3 and 4, focusing on the operating state of the slave unit 2.

The operation mode of the present apparatus can be selected from several types, but the flow shown in FIG. 3 shows the operation state of the child device 2 in the mode for preventing the misplacement of the bag and the pulling of the bag. It should be noted that even in this operation mode, it is possible to relatively effectively deal with the disposition even though the disposition prevention mode described later is not so.

First, as shown in FIG. 5, the master unit 1 is mounted on the traveler M, and the slave unit 2 is mounted on the bag 3. In this state, the power switch 9 of the master unit 1 and the power switch 18 of the slave unit 2 are mounted.
Is turned on. By turning on the power switch 9 of the parent device 1, the operation modes of the parent device 1 and the child device 2 are automatically set to the misplacement prevention mode.

In FIG. 3, the power switch 18 of the slave unit 2
Is turned on (S1), the child device 2 is set to an operating state corresponding to the misplacement prevention mode of the parent device 1, and the traveler M carries the bag 3 in this state. The alarm device 17 of the slave unit 2 is in an off state (S2), while the master unit 1 periodically outputs a predetermined output at a constant time interval T ₁ (for example, 2 seconds), for example, an output with a communication range of 5 meters. Signal (hereinafter referred to as "normal signal") is emitted automatically. The cordless handset 2 monitors the reception state of this normal state signal, judges whether or not the normal state signal is received from the base unit 1 (S3), and while receiving the normal state signal from the base unit 1, an alarm of the handset 2 The device 17 holds the off state (S2).

On the other hand, when the normal signal from the base unit 1 cannot be received after the time T _{1 has} passed since the last reception of the normal signal, the handset 2 issues an alarm signal to the base unit 1 (S
4). This alarm signal is transmitted with a higher output than the normal signal output from the master unit 1 and covers a wider communication range than the normal signal.

At the same time when the alarm signal is sent to the master unit S4, the timer 20 is activated. The timer 20 sets an alarm device activation standby time T ₂ (for example, 10 seconds) and monitors the elapse of this time (S5). Simultaneously with the elapse of time T _{2, the} alarm device 17 is activated and the slave unit 2 emits a loud alarm sound.

Here, the state in which the normal signal from the master unit 1 cannot be received by the slave unit 2, that is, the distance between the bag 3 to which the slave unit 2 is attached and the traveler M having the master unit 1 is the parent. It is in a state of being separated from the communication range of the signal emitted from the machine 1, and as such a case, the following cases can be considered.

(1) When a traveler has left the bag 3 and moved.

In this case, the alarm signal sent from the child device 2 activates the alarm device 8 of the parent device 1, and the traveler M immediately notices that the bag is left behind by this alarm.
If the traveler presses the alarm stop switch 12 of the base unit 1, the base unit 1
When an alarm stop signal is issued from the slave unit 2 and the slave unit 2 receives this signal, the alarm device 17 of the slave unit 2 does not operate (S6). This is so that the misplaced bag suddenly emits a loud alarm sound so that people around it are not surprised. When the alarm device activation standby time T ₂ has elapsed, the alarm device of the slave unit 2 is activated (S7), but the activation of the alarm device 17 is stopped when the activation stop signal from the master unit 1 is received. If necessary, the alarm device activation standby time T ₂ may not be set, and the alarm device 17 may be programmed (S7) to be activated (S7) at the same time as the alarm signal transmission S4 to the master unit 1.

(2) When the bag is stolen without the traveler's knowledge (for example, keeping the bag).

In this case, the traveler knows the fact of theft for the first time by operating the alarm device 8 of the base unit 1 by transmitting an alarm signal (S4) from the handset unit 2, so immediately at this point the alarm switch 11 of the base unit 1 is turned on. Press to send an alarm signal to the handset 2 (S8). Incidentally, this alarm signal also has a higher output than the normal signal. As a result, the handset 2 can receive the alarm signal even outside the normal signal reception range, and the alarm device 17 of the handset 2 emits a high alarm sound by receiving the alarm signal.

Usually, it is difficult for a thief to escape with a bag that keeps emitting a high alarm sound, and he will abandon his bag and escape. At this time, the abandoned bag emits an alarm sound, so it is easy to find this bag. In addition, even if the user forgets to press the alarm switch 12 of the parent device 1 due to upset feeling, or the bag 3 has already been taken out of the alarm signal reception range at the time of pressing the alarm switch 12, the alarm device Since the alarm device 17 of the child device 2 automatically operates when the operation standby time T ₂ has elapsed, the alarm device 17 of the child device 2 always operates in any case.

Next, when the bag is robbed by the traveler due to a hand pull or the like, if the traveler presses the alarm switch 11 of the base unit 1 at this time, the handset 2 receives this signal (S
8) Immediately, the alarm device 17 is activated (S7), and the robber will abandon the flight with the bag he robbed, as in the case described above.

FIG. 4 shows another operation mode of the slave unit 2.

The power switch 18 of the slave unit 2 is turned on.
On the other hand, when the power switch 9 of the parent device 1 is turned on, the misplacement prevention mode is automatically set.
After the switch is turned on, the operation of the apparatus is changed to the anti-pull-and-hold mode by depressing the anti-pull-and-hold mode switch 10. That is, in FIG. 4, when the slave unit 2 receives the disposition prevention mode signal from the master unit 1 (S9), the sensor (for example, the acceleration sensor) 20 in the slave unit 2 is turned on after a lapse of a certain time (time for the sensor to stabilize). Become. In this state, the alarm device 17 maintains the off state (S2), and the signal from the sensor 20 is monitored (S11).

When the sensor detects acceleration of a certain value or more, the alarm device 17 is activated (S7) by this detection signal and an alarm sound is emitted. At the same time, a signal from the sensor 20 causes the transmitter 13 to issue an alarm signal to the base unit 1 (S4), which activates the alarm device 8 of the base unit 1 (S).
12) Do. That is, in this operation mode, when the bag is lifted or the like, the sensor detects the acceleration and emits an alarm sound, so that the operator can immediately find out the misalignment. Further, even if the person who stole the bag escapes with the bag, the slave unit 2 continues to emit the alarm sound as in the case described above, and therefore the flight with the bag is abandoned.

In addition, when the bag is hit with a foot or the like in the above-mentioned hold-and-hold mode, the shock may cause the alarm device 17 of the slave unit 2 to operate. By pressing the alarm stop switch 12, the operation of the alarm device of the slave unit 2 is immediately stopped.

Although the present invention has been described by taking the case where the child machine is mounted on the bag and the owner of the parent machine is a traveler as an example, the present invention is not limited to this, and the belongings may be stolen. Of course, it is of course widely available.

[0036]

As described above, the present invention comprises a combination of a base unit and a base unit capable of wirelessly communicating with the base unit. The base unit is owned by a traveler or a bag holder, and the base unit is It is configured to be attached to or stored in belongings that may be lost, such as a travel bag, and configured to notify the owner of this fact as an alarm when the parent device and the child device are separated from the normal signal reception range Because of this, you can immediately notice that you have left your bag behind.

Further, since the slave unit issues an alarm when it becomes impossible to receive the normal signal, even if a bag or the like with the slave unit is stolen, the person who stole the bag emits a high alarm sound. It is virtually impossible to escape with a bag, and even a bag suitable for theft can be recovered with a high rate.
