Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to, for example, the prevention of lost or stolen children or the elderly, misplaced or stolen luggage, or misplaced or stolen children or the elderly. The present invention relates to a parent-child distance responsive alarm generator suitable for detecting luggage.

[0002]

2. Description of the Related Art Hitherto, a device (a parent-child distance response type alarm generating device) for preventing a child or an elderly person from getting lost or leaving or stolen luggage has been developed. This device is usually
It consists of a pair of a master unit having a (wireless) receiver and a slave unit having a (wireless) transmitter. For example, the distance between the master unit and the slave unit (hereinafter, sometimes referred to as a parent-child distance) is Utilizing that the reception level of the radio signal from the slave unit at the master unit decreases as the distance increases, the master unit and the slave unit are separated by a certain distance (the reception level at the master unit is higher than a predetermined value). When it becomes smaller, the master unit emits an alarm sound (alarm).

[0003] Therefore, for example, if a child or an elderly person is provided with a child device and a parent device is carried by a companion (administrator), even if the child or the old person tries to leave the companion, the child device or the old person can be separated from the parent device. If the distance from the child device exceeds a certain distance, the parent device will issue an alarm and notify the accompanying person of it, so the child or old man gets lost or missing without the attendant's notice Can be prevented from occurring.

[0004] In addition, if a child device is attached to luggage or the like and the owner carries the parent device, similarly, when the distance between the luggage and the owner is more than a certain distance, the parent device is alarmed. Is issued, it is also possible to prevent theft such as misplacement or luggage of luggage. In addition, such a device includes:
Contrary to the above, when the distance between the parent and the child becomes equal to or less than a certain distance (when the master and the child approach each other within a certain distance), a simple detection function for generating an alarm (by the master) is provided. There are also devices of this type, for example, this type of device is capable of detecting lost or stolen luggage, such as lost children or the elderly.

[0005]

However, such a conventional parent-child distance responsive alarm generating device has an alarm only when the parent-child distance exceeds a certain distance (or below a certain distance). Therefore, there is the following problem.・ When giving a child device to a child or an elderly person A companion with a parent device can recognize that a child or an elderly person has been separated from themselves by a certain distance or more (or approached within a certain distance). However, a child or an old man with a handset may not be aware of the alarm because the handset does not generate an alarm, and eventually becomes lost or missing (or discovers even when approaching a companion). I can't get it)
there is a possibility.

[0006] Since the child device does not generate an alarm, the accompanying person with the parent device can recognize that the child or the old man has left (or has come close to) himself, but the child or the old man can not recognize the child or the old man. It is not possible to recognize in which direction the person has left (or approached from) (that is, the current position of the child or the elderly), for example, in a crowded department store, amusement park, downtown area, etc. Then it is very likely that you will get lost (or not be accompanied by a companion).

[0007] When the child unit is attached to the luggage, since the child unit does not generate an alarm, even if the owner notices that the luggage has been left behind, if the owner forgets where to put the luggage, his / her luggage is immediately obtained. Cannot recognize where is (the current location of the package). Even if the luggage is stolen, the slave unit does not generate an alarm, so even if the owner notices the theft, it is almost impossible to identify the stolen person (the current position of the luggage) in busy traffic,
And cannot track down stolen people.

[0008] Even when a luggage is detected, the child device does not generate an alarm, so that even if the parent device generates an alarm, the luggage cannot be specified immediately. In addition, since the above-described device is provided as a dedicated device for the purpose of preventing lost children (missing), misplaced luggage, theft, etc.,
Companion (or the owner of the luggage) often forgets to carry the parent device or forgets to give the child or elderly person a child device (attach the child device to the luggage), and the original function (Purpose) cannot be fulfilled.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems. By making both a master unit and a slave unit generate an alarm in accordance with the distance from each other, a child or child can be more reliably identified. The purpose of the present invention is to provide an alarm device for detecting the distance between parents and children, which is useful for preventing lost or stolen luggage of old people, luggage, or detecting children, old people, luggage, etc. It is an object of the present invention to provide a parent-child distance response type alarm generation device which is excellent in portability and can exhibit the above.

13, the transceiver 22 includes an antenna 221, an antenna duplexer 222, a receiving unit 223, a transmitting unit 224, and the like. The control unit 23 includes a CPU 231, a ROM 232,
RAM 233, input / output interface unit (I / O I.O.
F) 234, mode switching unit 235, distance response mode setting / change unit 236, distance setting unit 237, direction setting unit 2
38, a spare time setting unit 240 and the like.

Here, in the clock section 21, TB [second
(Fourth, sixth) reference time pulse generating section] 211 is a reference time base signal (reference time pulse signal) necessary for clocking operation as a digital clock [keeping current time (date and time)] similarly to master clock 1. ), And the time counter unit 212 displays seconds and 10 seconds based on the reference time base signal generated by the TB 211 in the same manner as the time counter unit 112 of the master clock 1. ,
The DEC 213 outputs count values for the minute display, the 10 minute display, the hour display, and the 10:00 display. The DEC 213 decodes each count value output from the time counter 212 to display the seconds, LCD displays each value for 10 seconds display, minute display, 10 minutes display, hour display, 10:00 display
4B.

As described above, with respect to the clock section 21 of the slave timepiece 2 as well, the timekeeping counter section 212 performs the counting operation based on the reference time base signal from the TB 211, thereby providing the basic function of the digital timepiece. Timekeeping operation is realized. Next, in the transmitter / receiver 22, the antenna 221 is for transmitting and receiving signals to and from the master clock 1, and the antenna duplexer 222
Is one antenna 2 in the receiving unit 223 and the transmitting unit 224.
In this case, the signal from the master clock 1 received by the antenna 221 is also transmitted to the receiving unit 223.
And the signal from the transmitting unit 224 to the master clock 1 is output to the antenna 221 side so that the received signal does not sneak into the transmitting unit 224 and the transmitted signal does not sneak into the receiving unit 223. ing.

The receiving section 223 is for receiving a signal from the master watch 1 received through the antenna 221, and the received signal is input to the CPU 231 through the input / output interface section 234 of the control section 23. It has become. The transmission unit 224 is for generating a signal (transmission signal) for the master watch 1. Note that the slave clock 2 can determine the clock distance from the master clock 1 as long as the level of the received signal can be obtained. Therefore, there is no need to perform a special modulation process or the like on the transmission signal. It is not necessary to perform a special demodulation process or the like on the received signal.

Further, in the control unit 23, the CPU 23
1 is basically connected to the R connected via the bus 250.
By operating based on various programs, setting data, and the like stored in the OM 232 and the RAM 233, the display state of the LCD 4B of the slave timepiece 2 according to the various modes is controlled, and the output of an alarm is controlled. However, similarly to the master clock 1, in the distance response mode, the watch-to-watch distance between itself (the slave watch 2) and the master watch 1 is determined from the reception level of the signal from the master watch 1, and the determined clock interval is determined. It also has a function of outputting an alarm from the speaker 5B according to the distance.

That is, as shown in FIG.
Determines the distance between the master clock 1 and the slave clock 2 from the signal transmitted through the transceiver 12 (transmitter 124) of the master clock 1 and received through the transceiver 22 (receiver 223). It has a function as a second distance determining means 17B (hereinafter simply referred to as “determining means 17B”), and mainly includes the driver 25 and the speaker 5B, and the clock distance determined by the determining means 17B. Alarm generating means 18B (hereinafter, referred to as an alarm generating means) which generates an alarm in accordance with
It also functions as "alarm generating means 18B").

The alarm generator 18B performs the following functions (modes). In the determining means 17B, the clock distance from the master clock 1 is
A function of generating an alarm when the determination state continues for a predetermined time t1 measured based on the reference time base signal from the TB 211 after it is determined that the distance has become larger than the set distance R1 (separation detection mode).

After the determining means 17B determines that the clock distance to the master watch 1 has become smaller than the set distance R2 of the master watch 1, the determination state is counted based on the reference time base signal from the TB 211. A function of generating an alarm when the predetermined time t2 is continued (detection mode). That is, similarly to the alarm generating means 18A in the master watch 1, the alarm generating means 18B also generates an alarm based on the result obtained by adding the timekeeping information in the TB 211 to the information on the inter-clock distance determined by the determining means 17B. It is supposed to happen.

Various settings such as the clock distance, the reaction direction mode, and the spare time in the slave timepiece 2 can be made independently of the settings in the master timepiece 1. The distance response mode will not operate properly unless it operates under the same setting conditions as the clock distance, the reaction direction mode, the spare time, etc. of the clock 1, so that these clocks 1 and 2 will not operate. It is necessary to make the same setting (coordination) (However, it is better to set the sound quality and output interval of the alarm to be different from those of the master clock 1 so that it can be distinguished from the alarm of the master clock 1. good).

Such setting consistency can be obtained by performing the same setting operation as the setting operation on the master clock 1 also on the slave clock 2, or by modulating the setting data on the master clock 1, for example. It is also possible to use infrared rays or the like to transfer the data to the sub-watch 2. In the present embodiment, an example is described in which the settings are matched by the former method.

The input / output interface unit 234 is
CPU 231, clock unit 21, transceiver 22, mode switching unit 235, various setting units 236 to 238, 24 described above
0 and drivers 24 and 25. In this case, for example, the mode switching unit 23
5 and the various setting units 236 described above.
238 and 240 are output to the CPU 231 and control signals (LCD control signals,
Speaker control signals) are output to the drivers 24 and 25.

Further, the mode switching section 235 issues an instruction to switch between the various modes (current time (date and time) display mode, normal alarm mode, distance response mode, etc.) in response to the mode switching operation using the button 6B. The switching instruction is input to the CPU 231 through the input / output interface unit 234 and the bus 250, and the CPU 231 responds to the switching instruction by the LCD 231.
The display screen of 4B is switched via the driver 24.

The distance response mode setting / change unit 236
Generates a setting / change instruction by a setting / change request operation using the button 8B in the distance response mode (ON by the button 7B). The setting / change instruction is also transmitted through the input / output interface unit 234 and the bus 250. CPU2
In response to the setting / change instruction, the CPU 231 makes various setting items such as a clock distance (set distance R1, R2), a reaction direction mode, and a spare time (set time t1, t2), which serve as a reference for alarm generation. Is set / changeable (acceptable).

At this time, the CPU 231 sets this settable / changeable state to, for example, a setting item display (reference numeral 16) on the display screen of the LCD 4B as in the case of the master clock 1.
B) through the driver 24 to notify the user. Thus, in this case, too, the user
Each setting item can be easily set and changed while visually recognizing the item on the LCD 4B.

Then, the distance setting unit 237 and the direction setting unit 2
38, the spare time setting unit 240 further performs a data input operation for the distance, the reaction direction mode, and the spare time using the button 8B in the setting / changeable state as described above (however, the data input operation on the master clock 1 and the spare time setting operation). Same)
When there is, the input data is
34, output to the CPU 231 via the bus 250. When the CPU 231 receives these data, it accesses the RAM 233 via the bus 250 to rewrite the data of the corresponding setting item and change the setting. ing.

That is, the above-mentioned distance setting section 237 functions as a second timepiece distance setting changing means for changing the set value (set distance R1, R2) of the timepiece distance as a reference for generating an alarm. Spare time setting unit 24
0 functions as the set time changing means for making the spare times t1 and t2 variable similarly to the master timepiece 1. It should be noted that also for the main timepiece 2, the clock distance R1 (R2) and the spare time t1 (t
The setting of 2) may be performed simply by providing a dedicated numeric keypad or the like on the watch main body 3B.

Incidentally, the main timepiece 2 is not provided with an equivalent to the alarm setting section 139 of the main timepiece 1. That is, the slave timepiece 2 cannot turn off the alarm output like the master timepiece 1, and in the distance response alarm mode, the alarm output is always enabled. This is because a child or an old man is assumed as a person who carries the child timepiece 2 so that the child or the old man cannot turn off the alarm without permission.

Hereinafter, the operations of the master clock 1 and the slave clock 2 of the present embodiment configured as described above (the alarm generation device for the distance between parent and child: hereinafter sometimes simply referred to as "alarm generation device") will be described in detail. I do. However, in the following, the operation focusing on the distance response mode, which is a main part of the present embodiment, will be described, and the description of the operation of the function of a normal digital timepiece will be omitted.

(1) Description of Setting Operation First, the setting operation such as distance setting, reaction direction mode setting, and spare time setting in the distance reaction mode of the master watch 1 will be described with reference to the flowchart shown in FIG.
This will be described with reference to 9). In the master clock 1, the control unit 1
3 (CPU 131) monitors which setting (change) operation among the distance setting, the reaction direction mode setting, the spare time setting, and the alarm setting has been performed for itself (steps A1, A3, A5). , A7), for example, when a distance setting operation is performed (YE in step A1).
If determined to be S), the CPU 131 determines reference values (reception levels) Ref1 and Ref2 according to the set distances R1 and R2 for the above-described separation detection mode and detection mode (step A2). Note that the determined reference values Ref1, R
ef2 is stored in the RAM 133.

On the other hand, if a reaction direction mode setting operation is performed [if YES is determined in step A3 (however,
The CPU 131 performs setting of a direction mode according to the input reaction direction mode (including both after step A2 and after determination of NO in step A1) (stores the mode in RAM 133: step). A4).
At this time, when the distance detection mode is set, the CPU 131 displays, for example, “← →” on the LCD 4A, and when the detection mode is set, the CPU 131 displays “→→” on the LCD 4A.
By displaying "←", the set (current) mode is notified to the user (see reference numeral 16A in FIG. 2).

When the spare time setting operation is performed (when YES is determined in step A5 (including both after step A4 and after NO in step A3)), CPU 131 The spare time is set by storing the input data for the spare time [set time t1 (for the separation detection mode), t2 (for the detection mode)] in the RAM 133 (step A).
6).

Further, an alarm setting operation (ON / OFF)
When the operation is performed (after step A6 or NO is determined in step A5), the CPU 131 sets the alarm setting state (ON state, OF state) according to the setting operation.
The alarm setting (alarm output) is controlled to the ON state (from step A7 to step A8) or the OFF state (from step A7 to step A9) by storing the F state) in the RAM 133.

In this way, the master watch 1 can set / change each setting item independently for each setting item. On the other hand, the setting operation in the slave timepiece 2 is performed by the CPU 231 operating according to, for example, a flowchart (steps B1 to B7) shown in FIG. Since the alarm setting cannot be turned off, steps corresponding to steps A7 and A9 shown in FIG. 4 are omitted, and at least in the distance response mode, the alarm setting is always set to the ON state. (That is, the alarm setting of the RAM 233 cannot be rewritten).

However, the alarm setting may be changed (turned off) when, for example, a password or the like known only to the carrier of the master watch 1 is normally input. In addition to the alarm settings, the settings of the clock distance, reaction direction mode, spare time, and the like can be similarly changed only when a password or the like known only by the carrier of the master watch 1 is normally input. It may be. In particular, in the power OFF operation of the distance response mode using the button 7B of the child timepiece 2, such a password input is performed so that the wearer of the child timepiece 2 does not turn off the distance response mode without permission. It is better to enable it only when it is performed normally.

The other setting operations are performed in the same manner as the setting operation of the master timepiece 1 described above, and the reference values Ref1, Ref2 corresponding to the set distances R1, R2, the reaction direction mode, the spare time t1, Setting / change of t2 (storage in RAM 233) is performed. Further, when the setting data of the master watch 1 is received as described above, the received setting data only needs to be stored in the RAM 233, so that the above setting operation is not necessary.

(2) Description of Basic Operation During Operation Next, the basic operation when the above-described setting is completed in each of the master clock 1 and the slave clock 2 and the distance reaction mode is actually operated will be described. 6 (operation of the master watch 1) and FIG. 7 (operation of the slave watch 2) will be described in detail.

First, in the master clock 1, the CPU 131
M133 is accessed to confirm the setting of the reaction direction mode (step A11). As a result, for example, if the separation detection mode (“← →”) is set, the CPU 131
The (determination means 17A) compares the reception level _RL of the signal from the master watch 1 received by the reception section 123 with a reference value Ref1 stored in the RAM 133 and corresponding to the set distance R1 in the separation detection mode. As a result, the reception level _RL is smaller than the reference value Ref1 ( _RL <Ref1), that is, the clock-to-clock distance is larger than (set apart from) the set distance R1.
It is determined whether or not (YES route from step A11 to step A12).

If R _L <Ref1 (YES in step A12), the CPU 131
The timing information in the clock unit 11 is monitored (for example, the reference time base signal from the TB 111 is counted) (step A13), and a predetermined time (first set time) t1 in the separation detection mode set in the RAM 133 is determined. It is monitored whether the time has elapsed (step A14).

As a result, if the predetermined time t1 has not elapsed, the CPU 131 repeats the processing from step A12 (NO route of step A14), but if the predetermined time t1 has elapsed, the CPU 131 The count is cleared (step A15), and it is confirmed whether the alarm setting of the RAM 133 is ON (step A16).

At this time, if the alarm setting is OFF (alarm generation prohibited), the CPU 131 repeats the processing from the beginning (step A11) without generating an alarm (NO route in step A16). If the alarm setting is ON, the speaker 5A is driven via the driver 15 to output an alarm (from the YES route of step A16 to step A1).
7).

Thereafter, the CPU 131 again compares the reception level _RL with the reference value Ref1, and determines that the reception level _RL is equal to or more than the reference value Ref1 (R _L ≧ Re).
f1) That is, it is determined whether or not the inter-clock distance is within the set distance R1 (step A18). If the inter-clock distance is still larger than the set distance R1, an alarm is output unless the alarm setting is turned off. (NO route in step A18), and if the clock distance is within the set distance R1, the output of the alarm is stopped (from the YES route in step A18 to step A1).
9) The process from the beginning (step A11) is repeated.

In the above-mentioned step A12, while the clock distance is within the set distance R1, the clock information is not counted in the clock section 11 (once the clock distance becomes larger than the set distance R1). If the count has been performed, it is cleared: from the NO route of step A12 to step A20), the processing from the beginning (step A11) is repeated.

On the other hand, if the reaction direction mode is set to the detection mode (“→ ←”) in step A11, the CPU 131 (determination means 17A)
Level R _{L according} to the reception level _RL of the signal from the controller 133 and the set distance R2 in the detection mode stored in the RAM 133.
ef2, the reception level _RL becomes equal to the reference value Ref2.
(R _L > Ref2), that is, it is determined whether or not the clock distance to the slave timepiece 2 has become smaller (approached) than the set distance R2 (step A21 from the NO route of step A11).

Then, if R _L > Ref2 (YES in step A21), the CPU 131
In this case as well, the timer unit 11 monitors the timekeeping information (step A22), and monitors whether a predetermined time (second set time) t2 in the detection mode set in the RAM 133 has elapsed (step A23). ). As a result, if the predetermined time t2 has not elapsed, the CPU 131 repeats the processing from step A21 (NO route of step A23). However, if the predetermined time t2 has elapsed, the CPU 131 clears the count of the timing information. (Step A24), RAM
It is checked whether the alarm setting of 133 is ON (step A25).

At this time, if the alarm setting is OFF (alarm generation prohibited), the CPU 131 repeats the processing from the beginning (step A11) without generating an alarm (NO route in step A25). If the alarm setting is ON, the speaker 5A is driven via the driver 15 to output an alarm as in the case of the separation detection mode (YE in step A25).
Step A26 from the S route).

Thereafter, the CPU 131 again compares the reception level _RL of the signal from the slave timepiece 2 with the reference value Ref2, and determines that the reception level _RL is equal to or less than the reference value Ref2 (R _L ≦ Ref2). ) That is, it is determined whether or not the clock distance is equal to or longer than the set distance R2 (step A).
27) If the clock distance is still smaller than the set distance R2, the alarm output is continued (NO route in step A27), and if the clock distance is equal to or longer than the set distance R2, the alarm output is stopped. (Step A19 from the YES route of Step A27) to the beginning (Step A
The processing from 11) is repeated.

In step A21, while the clock distance is equal to or greater than the set distance R2, the clock information is not counted by the clock unit 11 (the clock time is temporarily smaller than the set distance R2). If the count has been performed, it is cleared: from the NO route of step A21 to step A28), the processing from the beginning (step A11) is repeated.

On the other hand, in the slave timepiece 2, the CPU 231 operates according to the flowchart (steps B11 to B26) shown in FIG. The state where it is determined that the clock distance from the master watch 1 is larger (smaller) than the set distance R1 (R2) is a predetermined time t1.
(T2) If continued, an alarm is output from the speaker 5B by the alarm generating means 18B, and thereafter, when the clock distance falls within the set distance R1 (not less than the set distance R2), the output of the alarm is stopped.

However, in the case of the slave timepiece 2, since the alarm setting is fixed to the ON state, as described above, the clock distance is set to the set distance R in the separation detection mode (detection mode).
If the state determined to be larger (smaller) than 1 (R2) continues for a predetermined time t1 (t2), an alarm is output unconditionally. That is, the child timepiece 2 (CPU 231)
(The flowchart shown in FIG. 7) is performed by the master clock 1 (C
The difference is that the ON / OFF state of the alarm setting is not confirmed (the steps corresponding to steps A16 and A25 are omitted) in the operation of the PU 131) (the flowchart shown in FIG. 6).

(3) Description of an Example of Actual Operation (Use) An example of an actual operation (use) of the alarm generator of the present embodiment will be described below based on the basic operation of the master clock 1 and the slave clock 2 as described above. For example, as schematically shown in FIGS. 8 and 9, the child clock 2 is carried by a child 32 (or an elderly person), and the parent clock 1 is carried by a companion (administrator) 31 such as a parent of the child 32. The case will be described.

(3-1) Description when Separation Detection Mode is Set First, the separation detection mode is set as the reaction direction mode for the master clock 1 and the slave clock 2, and the master clock 1 is set to the alarm setting ON state. Suppose that It is assumed that the setting for the master clock 1 and the slave clock 2 is performed by the accompanying person 31 respectively.

Then, for example, as shown in FIG.
FIG. 8 shows the state where the accompanying person 31 and the child 32 are together.
It is assumed that the child 32 moves away from the accompanying person 31 (or the accompanying person 31 from the child 32) as shown in FIG.
As it is, the child 32 moves away from the accompanying person 31 and FIG.
As shown in (c), when the distance between the clocks exceeds the set distance R1, the reception level _{RL of} each of the master clock 1 and the slave clock 2 becomes smaller than the reference value Ref1 (step shown in FIG. 6). A12 and YES are determined in step B12 shown in FIG. 7).
1 and 231 start monitoring the timekeeping information in the clock units 11 and 21.

In this state, if the child 32 does not return within the set distance R1 by the time the set time t1 has elapsed, the CPUs 131 and 231 respectively, as shown in FIG. An alarm is output from the speaker 5A and the speaker 5B of the child timepiece 2 to notify both the accompanying person 31 and the child 32 that the state where the distance between them is larger than the set distance R1 has continued for the set time t1 or more. Notice.

Thus, both the companion 31 and the child 32 can recognize that they are separated from each other by more than the set distance R1 for the set time t1 or more. Missing can be reliably prevented. In addition, by generating an alarm not only for the master clock 1 but also for the slave clock 2 as described above, the accompanying person 31 can easily recognize the alarm sound of the slave clock 2 even in the direction in which the child 32 is away (current position) ( Specified) can be prevented, and the child 32 can be more reliably prevented from getting lost or missing.

Here, the set time t1 can be changed through the spare time setting units 140 and 240, and the set distance R1 is also changed by the distance setting units 137 and 23.
7 can be changed through the setting time t according to the purpose of use of the master clock 1 and the slave clock 2 (alarm generation device).
1. The set distance R1 can be changed as appropriate, which greatly contributes to the improvement of the flexibility in use of the alarm generation device.

For example, in places where children 32 are likely to get lost, such as in a busy street such as a department store, an amusement park, or a downtown area,
If the set distance R1 and the set time t1 are set to be short (several meters and several seconds), the alarm of the clocks 1 and 2 will sound if the child 32 moves away from the accompanying person 31 for a short time. The possibility that the child 31 gets lost during a crowd can be greatly reduced.

In a home or the like, if the above set distance R1 is set to about several tens of meters, for example,
2 or the old man tries to get out of the house with the entrance door or gate open (without eyes)
When the number exceeds 1, each alarm sounds, so that the child or the elderly can be prevented from going missing.

Further, in a place with a small crowd or a place with a relatively good view, the child 32 will be within the range of the companion's eyes. Therefore, the set distance R1 and the set time t1 are set longer ( Tens of meters, tens of seconds)
It is unlikely that the child 32 gets lost. Therefore, in such a case, the number of alarm occurrences will be reduced as compared with the case where the set distance R1 and the set time t1 are set short as described above. Can be respectively reduced. At this time, with respect to the master clock 1, an alarm setting OFF operation is performed, and
The generation of an alarm may be prohibited by the alarm setting unit (alarm generation prohibiting means) 139, whereby the power consumption of the master watch 1 can be further reduced.

That is, in the present embodiment, an alarm is generated based on the result obtained by adding the time information of the digital clock (TB111) to the information of the clock distance, so that the alarm is generated only based on the distance between the clocks. Instead, the alarm is generated in consideration of time (time measurement information), so that various types of alarm generation in consideration of time can be realized. In addition, as for the alarm generation considering such time, there may be another variation in which an alarm is generated, for example, when the clock distance is longer than the set distance R1 at a certain set time.

By the way, as shown in FIG. 8 (c), after the clock-to-clock distance once becomes larger than the set distance R1, and as shown in FIG. 8 (e), until the set time t1 elapses, When the child 32 returns within the set distance R1,
Due to the spare time function, the master clock 1 and the slave clock 2 do not output an alarm. This prevents unnecessary alarm output.

For example, even if the child 32 wanders around the set distance R1 and the clock distance fluctuates near the set distance R1, no alarm is generated unless the set time t1 has elapsed. It is possible to prevent an alarm from occurring frequently every time the distance becomes larger than the set distance R1. Therefore, it is possible to reduce discomfort to the accompanying person 31, the child 32, and the surroundings due to the frequent occurrence of the alarm, and to further reduce the power consumption of the master watch 1 and the slave watch 2.

In the above-described separation detection mode, the alarm volume may be made variable according to the clock distance. For example, once the alarm is generated as described above, if the alarm volume of the slave clock 2 is increased as the clock distance increases, the accompanying person 31 can more reliably change the current position of the child 32. Can be identified,
Further, it is possible to effectively prevent the child 32 from getting lost or missing.

(3-2) Description when the detection mode is set First, the detection mode is set as the reaction direction mode for each of the master clock 1 and the slave clock 2, and the master clock 1 is set to the alarm setting ON state. Suppose you have Then, as shown in FIG. 9A, for example, the accompanying person 31 and the child 32 are separated from each other by a set distance R2 (or R1) or more (for example,
From the lost state), as shown in FIG. 9B, the child 32 approaches the accompanying person 31 (or the accompanying person 31 approaches the child 32), and the clock distance becomes the set distance R2.
6, the reception levels _{RL of} the master clock 1 and the slave clock 2 become larger than the reference value Ref2 (FIG. 6).
Are determined to be YES in step A21 shown in FIG. 7 and in step B20 shown in FIG. 7).
31 and 231 start monitoring the timekeeping information in the clock units 11 and 21.

In this state, if the child 32 stays within the set distance R2 even after the set time t2 (= t1 may have elapsed), the CPUs 131 and 231 respectively execute FIG.
As shown in the figure, an alarm is output from the speaker 5A of the master watch 1 and the speaker 5B of the slave watch 2 so that both the accompanying person 31 and the child 32 are in a state where the distance between them is closer than the set distance R2. It notifies that it has continued for the time t2 or more.

Thus, both the companion 31 and the child 32 can recognize that they are closer than the set distance R2 for the set time t2 or more, and the companion 31 and the child 32 can surely find each other. (Detect). In this way, not only the master clock 1 but also the child clock 2 generates an alarm, so that the accompanying person 31
It is possible to easily recognize even the direction (current position) of the child 32 approaching from the alarm sound of, and the child 32 can be found more reliably.

Also, in this case, the set time t2 can be changed through the spare time setting units 140 and 240, and the set distance R2 is also changed by the distance setting unit 1.
37 and 237, the set time t2 and the set distance R2 can be appropriately changed according to the purpose of use of the master clock 1 and the slave clock 2 (alarm generation device). It greatly contributes to the improvement of the flexibility in use.

For example, if the set distance R2 is set to be long (to several tens of meters), a wide range of detection can be performed, and if the set time t2 is set to be short (to several seconds), a clock can be obtained. Since an alarm is generated within a few seconds after the distance becomes shorter than the set distance R2, highly sensitive detection can be performed. In other words, even in this detection mode, the information on the distance between the clocks is stored in the digital clock (TB11).
By generating an alarm based on the result of adding the timing information of 1), it is possible to generate an alarm in consideration of time (timekeeping information) without generating an alarm merely due to the distance between clocks. Therefore, it is possible to realize various types of alarm generation in consideration of time. In this detection mode, for example, a variation may be considered in which an alarm is generated when the clock distance is shorter than the set distance R2 at a certain set time.

By the way, as shown in FIG. 9 (b), even if the time between clocks once becomes smaller than the set distance R2, as shown in FIG. 9 (d), before the set time t2 elapses, When the child 32 is separated from the set distance R2, the master clock 1 and the slave clock 2 do not output an alarm by the spare time function. Thereby, it is possible to prevent an alarm from being frequently generated every time the clock-to-clock distance becomes smaller than the set distance R2. Therefore, discomfort to the accompanying person 31, the child 32, and the surroundings due to the frequent alarm is generated. And the master clock 1,
The power consumption of the slave timepiece 2 can be further reduced.

Also in this detection mode, the master clock 1 is turned off by setting the alarm setting.
The alarm setting unit (alarm generation prohibiting means) 139 may prohibit the generation of an alarm. For example, when the distance between the clocks is approached to a certain extent, the alarm sounds of the children can be heard in duplicate, and it may be difficult to identify the current position of the child 32. By prohibiting the generation of the alarm 1 (either manual operation or automatic setting according to the clock distance), more reliable detection can be performed while reducing the power consumption of the master clock 1.

Further, also in this detection mode, the alarm volume may be made variable in accordance with the clock distance. For example, once the alarm is generated as described above, if the alarm volume of the child watch 2 is increased as the clock distance is reduced, the accompanying person 31 can more reliably determine the current position of the child 32. Since it can be specified, its detection performance can be further improved.

(A-1) Description of First Modification of First Embodiment In the above-described embodiment, a case has been described where the master timepiece 1 and the slave timepiece 2 are each provided with a spare time function. This spare time function may be omitted. That is, the master clock 1 and the slave clock 2 each generate an alarm when the clock distance becomes larger than the set distance R1 in the separation detection mode, and the clock distance becomes smaller than the set distance R2 in the detection mode. At this point, an alarm may be generated.

More specifically, this operation is performed in steps A13 to A15, A20, A22 to A24, and A28 shown in FIG. 6 and steps B13 to B15, B19, and B21 shown in FIG.
The processing is realized by the operation of the CPUs 131 and 231 in accordance with the flowchart in which the steps B23 and B26 are omitted. In other words, in the separation detection mode, the determining means 17A of the master watch 1 determines that the time between the watches is the (first) set distance R1.
Is determined to be larger than the set time R1, and the alarm generating means 18A of the master watch 1 generates an alarm when the determining means 17A determines that the clock distance is larger than the set distance R1. The determination means 17B determines that the clock distance is greater than the set distance R1, and the alarm generation means 18B of the slave timepiece 2 has determined that the clock distance is greater than the set distance R1. In that case, an alarm will be generated.

On the other hand, in the detection mode, the determination means 17A of the master clock 1 determines that the clock interval is smaller than the (second) set distance R2, and the alarm generation means 18A of the master clock 1 sets the clock interval. When the determining unit 17A determines that the distance is smaller than the set distance R2, an alarm is generated, and the determining unit 17B of the slave timepiece 2 determines that the inter-clock distance is smaller than the set distance R2. ,
The alarm generation means 18B of the slave timepiece 2 generates an alarm when the determination means 18B determines that the distance between the clocks is larger than the set distance R2.

Therefore, also in this case, in the separation detection mode, not only the master clock 1 but also the child clock 2 generates an alarm, so that the child 32 can be reliably prevented from getting lost or missing. In addition, it is possible to easily recognize (specify) even the direction in which the child 32 is away (current position). In the detection mode, not only the master clock 1 but also the child clock 2 generates an alarm, so that the accompanying person 31 can surely detect a lost child or a missing child 32. It is also possible to easily recognize the direction from the alarm sound to the direction in which the child 32 approaches (current position).

(A-2) Description of Second Modification of First Embodiment In the above-described embodiment, the master timepiece 1 (CPU 131) and the slave timepiece 2 (CPU 231) set the distance set in the separation detection mode (detection mode). An alarm is generated in consideration of R1 (R2) and a spare time (set time) t1 (t2). For example, in the distance detection mode (detection mode), two types of set distances R3 and R4 ( However, R3> R
4) [Setting distances R5 and R6 (where R5 <R6 and R5
5 = R4, R6 = R3)] may be taken into account to generate an alarm.

For example, in the separation detection mode, an alarm is generated when the master clock 1 (CPU 131) and the slave clock 2 (CPU 231) are apart from the set distance R3, and an alarm is generated when the master clock becomes shorter than the set distance R4. Stop,
In the detection mode, an alarm is generated when the clock distance is shorter than the set distance R5, and the alarm is stopped when the clock distance is longer than the set distance R6.

More specifically, such a function is provided by the master clock 1.
This is realized when the (CPU 131) operates according to the flowchart shown in FIG. 10 and the slave timepiece 2 (CPU 231) operates according to the flowchart shown in FIG. Hereinafter, the basic operation in operation of the master clock 1 and the slave clock 2 in this case will be described in detail. The setting of the set distances R3, R4 (R5, R6) for the master watch 1 and the slave watch 2 is performed in the same manner as the distance setting operation described above with reference to FIGS. 4 and 5, respectively. Distance R

When _RL > Ref5, it is determined that the clock-to-clock distance is smaller than the set distance R5.
It is checked whether the alarm setting state of M133 is ON (step A38 from the YES route of step A37).

As a result, if the alarm setting state is ON, the CPU 131 causes the speaker 5A to output an alarm (NO route from step A38 to step A39), and then sets the reception level of the signal from the slave timepiece 2 (step A38). R _L monitors whether smaller than the reference value Ref6 (step A40). If the alarm setting status is O
If it is in the FF state (alarm generation prohibited state), C
The PU 131 repeats the processing from the beginning (step A31) without generating an alarm (NO in step A38).
root).

After the occurrence of the alarm, the CPU 131 repeats the processing from step A33 until the reception level _RL of the signal from the slave timepiece 2 becomes smaller than the reference value Ref6. , The alarm continues to be generated (NO route in step A40), and the reception level _RL is changed to the reference value Re.
When the value becomes smaller than f6, the generation of the alarm is stopped (from the YES route of step A40 to step A3).
6).

That is, in the master timepiece 1 of this modification, the distance between the self (master timepiece 1) and the slave timepiece 2 is greater than the (fifth) set distance R3 in the separation detection mode. Is smaller than the set distance R3 (sixth).
It is determined that the distance between the clocks is smaller than the set distance R4, and the alarm generation means 18A generates an alarm when the determination means 17A determines that the distance between the clocks is larger than the set distance R3. Is the set distance R4

On the other hand, in the detection mode, the determination means 17A

Is larger than the (eighth) set distance R6, and the alarm generator 18A generates an alarm when the determiner 17A determines that the clockwise distance is smaller than the set distance R5. When the determining means 17A determines that the clock distance is larger than the set distance R6, the generation of the alarm is stopped.

On the other hand, the slave timepiece 2 is
Is a flowchart (steps B31 to B31) shown in FIG.
38), the same separation detection mode and detection mode as those of the master watch 1 are realized. However, the operation of the slave timepiece 2 (CPU 231) (the flowchart shown in FIG. 11) is different from the operation of the master timepiece 1 (CPU 131) (the flowchart shown in FIG. 10) in that the ON / OFF state of the alarm setting is not confirmed (step A33, A
(The step corresponding to step 38 is omitted).

That is, in the slave timepiece 2, first, the CPU 231
Checks the setting state of the reaction direction mode by accessing the RAM 233 (step B31). If the separation detection mode is set, the reception level R _L of the signal from the master clock 1 is set.
Is smaller than the reference value Ref3 ( _RL <Ref3) (step B32 from the YES route of step B31).

As long as R _L <Ref3, CP

When it is 3, it is determined that the time between clocks is greater than the set distance R3, an alarm is output from the speaker 5B (from the YES route of step B32 to step B).
33) It is monitored whether or not the reception level _RL of the signal from the master watch 1 becomes larger than the reference value Ref4 (step B34).

After the occurrence of the alarm, the CPU 231 continues to generate the alarm until the reception level _RL of the signal from the slave timepiece 2 becomes larger than the reference value Ref4 (NO route in step B34). _{When L} becomes larger than the reference value Ref4, the generation of the alarm is stopped (from the YES route of step B34 to step B3).

On the other hand, when the detection mode is set as the reaction direction mode, the CPU 231 monitors whether the reception level _RL of the signal from the master clock 1 is higher than the reference value Ref5 ( _RL > Ref5). (Step B3

5).

That is, in the slave timepiece 2 of the present modification, the distance between the self (slave timepiece 2) and the master timepiece 1 is greater than the (fifth) set distance R3 in the separation detection mode. Is smaller than the set distance R3 (sixth).
It is determined that the distance between the clocks is smaller than the set distance R4, and the alarm generation means 18B generates an alarm when the determination means 17B determines that the distance between the clocks is larger than the set distance R3. Is the set distance R4

When the determining means 17B determines that the clock-to-clock distance is larger than the set distance R6, the generation of the alarm is stopped.

(2) Description of Actual Operation (Use) Example Next, based on the basic operation of the master timepiece 1 and the slave timepiece 2 in the second modification of the first embodiment as described above, an alarm of this modification is provided. Regarding an actual operation (use) example of the generator, also in this case, the child clock 2 is carried by the child 32 (or the elderly) and the master clock 1 is A case will be described as an example in which a companion 31 such as 32 is carrying.

(2-1) Description when Separation Detection Mode is Set First, the separation detection mode is set as the reaction direction mode for the master clock 1 and the slave clock 2, and the master clock 1 is set to the alarm setting ON state. Suppose that Then, for example, as shown in FIG. 12 (a), from the state where the accompanying person 31 and the child 32 are together, as shown in FIG. 12 (b), the child 32 is moved from the accompanying person 31 (or from the accompanying person 31). Move away from the child 32).

When the child 32 moves away from the accompanying person 31 and the clock distance exceeds the set distance R3 as shown in FIG. 12 (c), the master clock 1 and the child clock 2 Since the reception level _RL becomes smaller than the reference value Ref3 (determined as YES in step A32 shown in FIG. 10 and step B32 shown in FIG. 11), the speaker 5A of the master watch 1 and the speaker 5B of the slave watch 2 An alarm is output to notify both the companion 31 and the child 32 that the distance between them is greater than the set distance R3.

Accordingly, it is assumed that the child 32 comes closer to the accompanying person 31 than the set distance R3 and returns to the accompanying person 31, for example, as shown in FIG. However, in the present modified example, when the inter-clock distance is shorter than the set distance R3, it is determined NO in Step A35 of FIG. 10 and Step B34 of FIG. 11, so that both the master clock 1 and the slave clock 2 Without stopping the generation of the alarm, FIG.
As shown in (2), when the clock distance becomes shorter than the set distance R4, the generation of the alarm is stopped.

That is, in the separation detection mode of this modification,
Once the clock distance between the master clock 1 and the slave clock 2 once exceeds the set distance R3 and an alarm occurs,
The occurrence of the alarm is not stopped between the set distance R3 and the set distance R4 (the dead zone for stopping the alarm is set between the set distance R3 and the set distance R4).

Therefore, after the distance between the master watch 1 and the slave watch 2 becomes greater than (or apart from) the set distance R3, an alarm is generated unless the distance between the master watch 1 and the slave watch 2 is smaller than the set distance R4, which is smaller than the set distance R3. Will continue to do so
According to the first embodiment, the same effects as those in the above-described separation detection mode can be obtained, and furthermore, the lost or missing of the child 32 or the elderly can be prevented.

(2-2) Description when the detection mode is set Also in this case, the detection mode is set as the reaction direction mode for the master clock 1 and the slave clock 2, and the master clock 1 is set to the alarm setting ON state. Suppose that Then, for example, as shown in FIG.
13B are separated from each other by more than a set distance R5 (= R4 may be used) (for example, lost).
As shown in FIG. 13, it is assumed that the child 32 approaches the accompanying person 31 (or the accompanying person 31 approaches the child 32), and as shown in FIG. 13 (c), the clockwise distance becomes closer than the set distance R5.

Then, in master timepiece 1 and slave timepiece 2, the reception level _{RL of} each other becomes larger than reference value Ref5 (YES in step A37 shown in FIG. 10 and step B36 shown in FIG. 11). Therefore, an alarm is output from each of the speakers 5A and 5B to notify both the accompanying person 31 and the child 32 that the distance between them is closer than the set distance R5.

Thereafter, for example, as shown in FIG. 13 (d), it is assumed that the child 32 is separated from the accompanying person 31 again, and the clock-to-clock distance becomes larger than the set distance R5, despite the occurrence of an alarm. . However, at this time point, the master clock 1 and the slave clock 2 do not stop generating an alarm (step A34 in FIG. 10 and step B36 in FIG. 11).
Therefore, as shown in FIG. 13E, the generation of the alarm is stopped when the clock-to-clock distance is further away from the set distance R6.

That is, in the detection mode of this modification, once the clock distance between the master watch 1 and the slave watch 2 once approaches the set distance R5, an alarm is generated, and then the set distance R5 and the set distance R6 are set. In this case, the generation of the alarm is not stopped (the area between the set distance R5 and the set distance R6 is a dead zone for stopping the alarm).

Therefore, after the distance between the master clock 1 and the slave clock 2 becomes smaller than (approaches) the set distance R5,
The alarm will continue to be generated unless the distance from each other is larger than the set distance R6 which is larger than the set distance R5.
According to the first embodiment, the same effects as those of the above-described detection mode can be obtained, and moreover, a lost child, a lost child 32 or an old man can be detected.

(A-3) Others The alarm generation means 18B in the sub-timepiece 2 is
It is also possible to use a reference time base signal from the TB 111 to generate an alarm after a predetermined time from a reference time defined by the master clock 1. In other words, it is possible to set so that the alarms of the master clock 1 and the slave clock 2 sound, for example, several minutes to several tens minutes or several hours after a certain time (reference time).

The alarm generating means 18B is provided with a
It is also possible to use the reference time base signal from 11 to generate an alarm every predetermined time from the reference time specified by the master clock 1. That is, a certain time (reference time)
For example, the alarm of the master clock and the slave clock can be set to sound every several seconds to several minutes or every tens of minutes. If such a setting is made, even if the child 32 or the old man is allowed to play freely in a park or the like for a few minutes to several tens or several hours from a certain time, the child clock is made several minutes to tens of minutes or several hours later. 2
The child's 32 and the elderly are accompanied by the companion 3
The time to return to 1 can be recognized, so that the child 32 and the elderly do not get lost.

Here, in this case, the first
If the alarm generating means 18A generates an alarm in response to the alarm at the slave clock 2, the master clock 1 also generates an alarm at the same timing as the slave clock 2, so that the distance between the clocks is large. Also, for example, the companion 31 can recognize the time to pick up the child 32 or the elderly (as will be described later, when the child watch 2 is attached to luggage or the like, the time to carry the luggage). It is possible to reduce the occurrence of lost or missing (for example, misplaced or stolen luggage) of the elderly or the elderly.

Note that the sub-watch 2 may be attached to luggage or the like, and if the owner of the luggage carries the main watch 1, the above-described alarm generation operation causes the separation watch mode.
Missing or stolen luggage can be reliably prevented, and in the detection mode, luggage can be reliably detected. In particular, in the alarm generation device of the present embodiment, not only the master clock 1 but also the slave clock 2 generates an alarm, so that the owner of the luggage can easily recognize not only the distance to the luggage but also the position of the luggage. Therefore, compared to a case where only the master clock 1 generates an alarm, it is possible to more reliably prevent misplacement or theft of luggage and detect luggage. Further, even if the luggage or the like is stolen, the slave clock 2 generates an alarm, so that the stolen person can be easily tracked.

Furthermore, in the above-described embodiment and each of the modifications, since both the master watch and the slave watch 2 are configured as digital wrist watches (portable watches), they are extremely excellent in portability, and the Is interested and can be carried by an adult without discomfort. For example, a child 32 or an old man forgets to carry (or attaches to) luggage 2 or a companion 31 (or luggage). It is also possible to significantly reduce the case where the owner) forgets to carry the master watch 1 and cannot perform the essential functions as described above.

In the above-described embodiment and each of the modifications, the master timepiece 1 and the slave timepiece 2 have both the separation detection mode and the detection mode, respectively. May be configured. In this case, the operations of the CPUs 131 and 231 are simplified, and the amount of memory required for the ROMs 132 and 232 and the RAMs 133 and 233 can be reduced.
Can be reduced in size.

Furthermore, in the above-described embodiment and each of the modifications, the case has been described in which the master clock 1 and the slave clock 2 are each configured as a digital wristwatch. For example, the watch may be configured as a pocket watch, a small travel watch, or the like, or may be configured as an analog watch as long as it operates at least based on a reference time base signal.

The master timepiece 1 and the slave timepiece 2 may be configured to have the same or similar shape and design as a pair watch or the like, for example, or according to the preference of the user (user). May have different shapes and designs. (B) Description of Second Embodiment FIG. 14 is a schematic diagram showing a configuration of a parent-child distance response type alarm generation device as a second embodiment of the present invention.

Therefore, in the second embodiment, for example, FIG.
As shown in FIG. 4, the frequency of the signal (radio wave) transmitted by the slave clock 2-i is changed for each slave clock 2-i as f _i , and the frequency of the received signal is changed in the master clock 1-1. From f _i , it is possible to identify which slave clock 2-i the signal is from. For this reason, master clock 1-1 of the second embodiment.

However, the CPU 131 according to the present embodiment has a function of identifying the slave clock 2-i from the signals separated and received for each frequency f _{i by} each of the filters 125-i. In the same manner as in the first embodiment, the clock time is determined for the signal from the slave timepiece 2-i, and an alarm is generated through the speaker 5A according to the determined clock distance.

When the distance becomes larger than the set distance R1 (or becomes smaller than a certain set distance R2 in the detection mode), an alarm is not immediately generated, but the state is set for a predetermined time t1 (t2) (for example, several seconds to several tens of seconds). )
If it continues, an alarm is generated.

The other constituent elements (those denoted by the same reference numerals as those shown in FIG. 2) are the same as or similar to those described above with reference to FIG. 2, and a detailed description thereof will be omitted. .

That is, the CPU 23 in each slave clock 2-i
1 also determines the distance between itself (child clock 2) and master clock 1-1 from the signal transmitted through the transceiver 12A of the master clock 1-1 and received through its own transceiver 22 (receiving unit 223). And has a function as a fourth distance determining means 17B '(hereinafter simply referred to as "determining means 17B'"), and is mainly determined by the determining means 17B 'together with the driver 25 and the speaker 5B-i. Fourth alarm generating means 18B 'for generating an alarm according to the set clock distance.

The same operation as the distance response mode (separation detection mode, detection mode) of the embodiment is realized.

As a result, in the separation detection mode, the same operation and effect as in the first embodiment can be obtained in the relationship between the master clock 1-1 and the individual slave clocks 2-i.
-It is possible to reliably prevent a lost person or a missing person from all of the carriers (children and elderly people). On the other hand, in the detection mode, the same operation and effect as in the first embodiment can be obtained in the relationship between the master clock 1-1 and the individual slave clocks 2-i. And the elderly).

Further, when the slave timepieces 2-i are respectively attached to a plurality of luggage or the like, the same operation and effect as those of the first embodiment can be obtained, and the carrier of the master timepiece 1-1 (owner of the luggage).
Can easily recognize which luggage is where, so that all luggage can be prevented from being misplaced or stolen, and luggage can be detected.

Further, also in the present embodiment, the master clock 1-1,

It is also possible to significantly reduce the possibility that the companion (or the owner of the luggage) forgets to carry the master watch 1-1 and loses its original function as described above. .

As in the first embodiment, the CPU 131 performs various settings such as distance setting, reaction direction mode setting, and spare time setting for the master watch 1-1 by the flowchart shown in FIG. 4 (steps A1 to A9).

In this embodiment, for example, the button 6C (6D) is mainly used for power ON / OFF and the button 7C
(7D) is used for setting / changing the distance / direction (reaction direction mode) in the distance response type alarm mode, and the button 8C is used for turning on / off the distance response type alarm (alarm output) and adjusting the alarm volume. Suppose The master unit 1 'and the slave unit 2' of the present embodiment are respectively
Built-in transceiver and generates an alarm according to the reception level of each other's radio waves (signals) (that is, each other's distance) (distance response type alarm mode: hereinafter simply referred to as "distance response mode") Sometimes).
That is, the alarm generation device according to the present embodiment has the first
Instead of being configured as a digital timepiece as in the embodiment, it is configured as a dedicated device for preventing lost children, misplaced luggage, theft, and the like.

For this reason, the master unit 1 'and the slave unit 2' basically have a configuration in which the clocking functions (clock units 11 and 21) are omitted from the configurations shown in FIGS. 2 and 3, respectively. I have. That is, as shown in FIG.
A transceiver (fifth transceiver) for transmitting / receiving signals (radio waves) to / from slave unit 2 '(transmitter / receiver 22D: see FIG. 19)

5 'and the like.

Then, as shown in FIG. 2, for example,
The transmitter / receiver 12C includes an antenna 121 and an antenna duplexer 1 similar to those described in the first embodiment.
The control unit 13 'includes a CPU 131', a ROM 132, a RAM 13

4, distance response mode setting / change unit 136, distance setting unit 1
37, a direction setting unit 138, an alarm setting unit 139, and the like.

That is, the master unit 1 '(control unit 1) of this embodiment
3 ') is dedicated to the distance response mode, so that FIG.
Since the mode switching unit 135 shown in FIG. 1 is not required and the timekeeping function (clock unit 11) is not provided unlike the first embodiment, the spare time setting unit 140 is not required. The other constituent elements (those denoted by the same reference numerals as those shown in FIG. 2) are the same as or similar to those described above with reference to FIG. 2, and a detailed description thereof will be omitted.

Then, in the control section 13 ', the CPU 1
Basically, 31 ′ operates based on various programs and setting data stored in the ROM 132 and the RAM 133 connected via the bus 150, thereby controlling the display state of the LCD 4C and generating an alarm. Although output control is performed, also in the present embodiment, the parent-child distance between itself (the parent device 1 ′) and the child device 2 ′ is determined from the reception level of the signal from the child device 2 ′. It has a function to output an alarm from the speaker 5C according to the parent-child distance.

That is, as shown in FIG.
1 ′ is transmitted from the transmitter / receiver 22D (transmitter 224: see FIG. 19) of the slave unit 2 ′ and received through the own transceiver 12C (receiver unit 123) to receive the signal from the slave unit 2 ′ and the slave unit 1 ′. It has a function as a fifth distance determining means 17C (hereinafter, simply referred to as "determining means 17C") for determining a distance between the driver 15 'and the driver 15'.
Together with the speaker 5C, it functions as a fifth alarm generator 18C (hereinafter simply referred to as "alarm generator 18C") that generates an alarm in accordance with the distance between the parent and child determined by the determiner 17C.

More specifically, also here, the alarm generation means 18C
Performs the following functions (modes). A function of generating an alarm when the determining means 17C determines that the distance between the parent and child with the child device 2 'is greater than a certain set distance R7 (separation detection mode). A function of generating an alarm when the determining means 17C determines that the distance between the parent and child with the child device 2 'is smaller than a certain set distance R8 (detection mode).

These separation detection / detection modes can be arbitrarily selected by a reaction direction mode setting operation. Also,
Also in this case, as the set distances R7 and R8, for example, arbitrary values in the range of several meters to several tens of meters are set, and different values (R7 ≠ R8) may be set, or may be the same. A (common) value (R7 = R8) may be set. Further, the set distances R7 and R8 can be appropriately changed.

On the other hand, as shown in FIG. 19, the slave unit 2 'has substantially the same configuration as the master unit 1' described above.
The same transceivers as those in master unit 1 '(sixth
(Transmitter / receiver) 22D, a control unit 23 ', a driver 24', a driver 25 ', and the like. Further, as shown in FIG. 19, the transmitter / receiver 22D includes an antenna 221, an antenna duplexer 222, a receiver 223, a transmitter 224, etc. similar to those described above with reference to FIG. CPU 231 ', ROM 232,
RAM 233, input / output interface unit (I / O I.O.
F) 234, a distance response mode setting / change unit 236, a distance setting unit 237, a direction setting unit 238, and the like.

That is, the slave unit 2 ′ (control unit 2)
Similarly to the first embodiment, 3 ′) is not provided with an equivalent to the alarm setting unit 139 in the base unit 1 ′ in order to prevent a child or an elderly person from turning off the alarm without permission. The alarm output cannot be turned off. The other constituent elements (those denoted by the same reference numerals as those shown in FIG. 3) are the same as or similar to those described above with reference to FIG. 2, and a detailed description thereof will be omitted.

In the control unit 23 ', the CPU 2
31 'basically controls the display state of the LCD 4D of the slave unit 2' by operating based on various programs and setting data stored in the ROM 232 and the RAM 233 connected via the bus 250. And the output of an alarm is controlled. As in the case of the base unit 1 ', the master (child unit 2') and the base unit 1 ' It also has a function of judging the distance and outputting an alarm from the speaker 5D according to the determined parent-child distance.

That is, as shown in FIG.
1 'is transmitted through the transceiver 12C (transmitting unit 124) of the master unit 1' and transmitted and received by its own transceiver 22D (receiving unit 223).
Distance determining means 17D for determining the distance between itself (slave 2 ') and master 1' from the signal received through
(Hereinafter, simply referred to as "determining means 17D"), and generates an alarm mainly in accordance with the distance between the parent and child determined by the determining means 17D together with the driver 25 'and the speaker 5D. Sixth alarm generating means 18
D (hereinafter simply referred to as “alarm generating means 18D”).

The alarm generating means 18D performs the following functions (modes). In the determining means 17D, the distance between the parent device and the parent device 1 'is
Function to generate an alarm when it is determined that the distance has become larger than the set distance R7 (separation detection mode). In the determining means 17D, the distance between the parent device and the parent device 1 'is
Function to generate an alarm when it is determined that the distance becomes smaller than the set distance R8 (detection mode).

It should be noted that various settings such as the parent-child distance and the reaction direction mode in the child device 2 'can be made independently of the settings in the parent device 1' as in the first embodiment. However, basically, unless the operation is performed under the same setting conditions as the respective settings such as the distance between the parent and child and the reaction direction mode in the parent machine 1 ', the apparatus will not operate normally. It is necessary to make the same setting (matching) in the slave unit 2 '(however, the sound quality and output interval of the alarm are different from those of the master unit 1' so as to be distinguishable from the alarm of the master unit 1 '). It is better to set it differently).

[0194] Such matching of the settings can be performed by performing the same setting operation as that of the master unit 1 'on the slave unit 2', or the master unit 1 '.
The setting data can be obtained by transferring the setting data to the slave unit 2 'by modulating or using infrared rays, for example. Note that the present embodiment also exemplifies a case in which settings are matched by the former method.

The operation of the master unit 1 'and the slave unit 2' (alarm generation device) of the third embodiment configured as described above will be described in detail below. (1) Description of Setting Operation First, operations such as distance setting, reaction direction mode setting, and alarm setting in the base unit 1 'will be described with reference to a flowchart (steps C1 to C7) shown in FIG.

In master unit 1 ', control unit 13' (CPU 13
1 ') monitors which setting (change) operation among the distance setting, the reaction direction mode setting, and the alarm setting has been performed for itself (steps C1, C3, and C).
5) For example, when a distance setting operation is performed (when YES is determined in step C1), the CPU 131 'sets each of the set distances R for the above-described separation detection mode and detection mode.
Reference values (reception levels) Ref7, Re according to R7, R8
f8 is determined (step C2). The determined reference values Ref7 and Ref8 are stored in the RAM 133.

On the other hand, when the reaction direction mode setting operation is performed [if YES is determined in step C3 (however,
The CPU 131 'sets the direction mode according to the input reaction direction mode (including the mode after the step C2 and after the determination of NO in the step C1) (the mode is stored in the RAM 133: Step C4).
At this time, when the distance detection mode is set, the CPU 131 'displays, for example, "← →" on the LCD 4C, and when the detection mode is set, the CPU 131' displays "→" on the LCD 4C.
By displaying "←", the set (current) mode is notified to the user (see reference numeral 16A in FIG. 18).

When an alarm setting operation (ON / OFF operation) is performed (after step C4 or when NO is determined in step C3), the CPU 131 '
Alarm setting status according to the setting operation (ON status, O
By storing the FF state in the RAM 133, the alarm setting (alarm output) is controlled to the ON state (from step C5 to step C6) or the OFF state (from step C5 to step C7).

As described above, in the base unit 1 ', it is possible to set / change each setting item independently for each setting item. On the other hand, the setting operation in the slave unit 2 'is performed by the CPU 231' operating in accordance with, for example, a flowchart (steps D1 to D5) shown in FIG. In FIG. 20, since at least the alarm setting cannot be turned off, the steps corresponding to steps C5 and C7 shown in FIG. 20 are omitted, and in the power-on state, the alarm setting is always on. (That is, the alarm setting of the RAM 233 cannot be rewritten).

However, as in the first embodiment, the alarm setting can be changed (turned off), for example, when a password known only to the carrier of the base unit 1 'is normally input. You may do so. Further, in addition to the alarm setting, the setting of the parent-child distance and the reaction direction mode may be similarly changed only when a password or the like known only by the person carrying the base unit 1 'is normally input. . In particular, when the power supply is turned off using the button 6B of the handset 2 ', such a password is normally input so that the person carrying the handset 2' does not turn off the power without permission. It is better to make it possible only for

The other setting operations are performed in the same manner as the above-described setting operation of the base unit 1 ', and the reference values Ref7 and Ref8 and the setting and changing of the reaction direction mode according to the set distances R7 and R8. (Storage in RAM 233)
Is performed. Further, when the setting data of the master unit 1 'is received as described above, the received setting data only needs to be stored in the RAM 233, so that the above setting operation is not necessary.

(2) Description of Basic Operation in Operation Next, the basic operation in the case where the above-described setting is completed in each of the master unit 1 'and the slave unit 2' and the distance response mode is actually operated. 22 (operation of the master unit 1 ') and FIG. 23 (operation of the slave unit 2') will be described in detail.

First, in master unit 1 ', CPU 131'
By accessing the AM 133, the setting of the reaction direction mode is confirmed (step C11). As a result, for example, if the separation detection mode (“← →”) is set, the CPU 13
1 ′ (determining means 17C) determines the reception level _RL of the signal received from the base unit
Is compared with the reference value Ref7 corresponding to the set distance R7 in the separation detection mode, and the reception level _RL is smaller than the reference value Ref7 ( _RL <Ref7), that is, the parent-child distance is set. It is determined whether or not the distance R7 has become greater than (or away from) the distance R7 (step C12 from the YES route of step C11).

Then, while the distance between the parent and child is within the set distance R7, the CPU 131 'initially (step C11)
From step (NO route of step C12)
Is _RL <Ref7 (YES in step C12)
), The alarm setting of the RAM 133 is ON
Check whether it is in the state (Step C1)
3).

At this time, if the alarm setting is OFF (alarm generation prohibited), the CPU 131 '
The process from the beginning (step C11) is repeated without generating an alarm (NO route of step C13). If the alarm setting is ON, the driver 15 'is set.
The speaker 5C is driven via the CPU to output an alarm (from the YES route of step C13 to step C1).
4).

Thereafter, the CPU 131 'again executes
By comparing the reception level R _L and the reference value Ref7, the reception level R _L is equal to or greater than the reference value Ref7 (R _L ≧ R
ef7) That is, it is determined whether or not the parent-child distance is within the set distance R7 (step C15). If the parent-child distance is still larger than the set distance R7, an alarm is output unless the alarm setting is turned off. (NO route of step C18), and if the parent-child distance is within the set distance R7, the output of the alarm is stopped (YES route of step C15 to step C1).
6) The process from the beginning (step C11) is repeated.

On the other hand, if the reaction direction mode is set to the detection mode ("→ ←") in step C11, the CPU 131 '(determination means 17C) sets the reception level R of the signal from the slave unit 2'. _L and a reference value Ref8 corresponding to the set distance R8 in the detection mode stored in the RAM 133, and the reception level _RL is set to the reference value Re.
It is determined whether the value is larger than f8 (R _L > Ref8), that is, whether the distance between the parent and child with the child device 2 'is smaller than (approached to) the set distance R8 (N in step C11).
Step C17 from the O route).

While the parent-child distance is equal to or longer than the set distance R8, the CPU 131 'initially (step C11)
Is repeated (NO route of step C17)
Is R _L > Ref8 (YES in step C17)
In this case, it is checked whether the alarm setting of the RAM 133 is ON (step C18).

At this time, if the alarm setting is OFF (alarm generation prohibited), the CPU 131 '
The process from the beginning (step C11) is repeated without generating an alarm (NO route of step C18), but if the alarm setting is ON, the driver 15 'is turned on in the same manner as in the separation detection mode. Speaker 5C through
Is driven to output an alarm (YES route from step C18 to step C19).

Thereafter, the CPU 131 'again executes
By comparing the reception level R _L and the reference value Ref8, the reception level R _L is equal to or less than the reference value Ref8 (R _L ≦ R
ef8), that is, it is determined whether or not the parent-child distance is equal to or greater than the set distance R8 (step C20). If the parent-child distance is still smaller than the set distance R8, the output of the alarm is continued (NO route of step C20). If the parent-child distance is equal to or greater than the set distance R8, the output of the alarm is stopped (YES route from step C20 to step C16), and the process from the beginning (step C11) is repeated.

On the other hand, in the slave unit 2 ', the CPU 231'
The flowchart shown in FIG. 23 (steps D11 to D1)
By operating according to 8), similar to the parent device 1 ',
When the determining unit 17D determines that the parent-child distance is larger (smaller) than the set distance R7 (R8) in the separation detection mode (detection mode), the alarm generating unit 18D
Outputs an alarm from the speaker 5D, and then
When the distance between the parent and the child becomes less than the set distance R7 (more than the set distance R8), the output of the alarm is stopped.

However, in the case of the handset 2 ', since the alarm setting is fixed to the ON state, as described above, the distance between the parent and child is set to the set distance R in the separation detection mode (detection mode).
If it is determined to be larger (smaller) than 7 (R8), an alarm is output unconditionally. That is, the above-mentioned slave unit 2 '
The operation of the CPU 231 '(the flowchart shown in FIG. 23) is the same as the operation of the parent device 1' (the CPU 131 ') (the flowchart shown in FIG.
The difference is that the OFF state is not checked (the steps corresponding to steps C13 and C18 are omitted).

As described above, also in the alarm generating device of the third embodiment, according to the parent-child distance between the parent device 1 'and the child device 2',
Since the master unit 1 'and the slave unit 2' each generate an alarm, the same operation and effect as those of the alarm generation device described in the first embodiment can be obtained. That is, the following effects are mainly obtained. Both the carrier (parent or accompanying person) of the base unit 1 'and the carrier (child or elderly person) of the slave unit 2' can recognize each other's distance from each other. It is possible to reliably prevent the user from getting lost or not being able to find it.

Since not only the parent device 1 'but also the child device 2' generates an alarm, the person carrying the parent device 1 'can easily recognize even the current position of the child or the old man, which is more reliable. In addition, it is possible to prevent a child or an old man from getting lost or not being able to find it. When the slave unit 2 'is attached to luggage or the like, an alarm is generated not only for the master unit 1' but also for the slave unit 2 'in accordance with the distance to the luggage. Owner)
Since it is possible to easily recognize not only the distance to the baggage but also the position of the baggage, it is possible to more securely prevent misplacement or theft of the baggage as compared with the case where only the base unit 1 'generates an alarm. , Can detect luggage.

In this embodiment, as described in the second modification of the first embodiment, two different set distances may be set to provide a dead zone for stopping the alarm. Further, the parent device 1 'and the child device 2' of the present embodiment may be configured to have only one of the separation detection mode and the detection mode.
Also in this case, the operations of the CPUs 131 ′ and 231 ′ are simplified, and the ROMs 132 and 232 and the RAM 13
3, 233, it is possible to reduce the size of the master unit 1 'and the slave unit 2'.

Further, the above-mentioned alarm generation device is not limited to the prevention of lost children, misplaced luggage, theft, etc., but may be configured as a device that is shared with other functions such as a game function. In addition, the above-described master unit 1 'and slave unit 2' may be configured as ordinary units without LCDs 4C and 4D, respectively. Further, the parent device 1 'and the child device 2' may be configured as accessories such as a ring, a pendant, a brooch, a bracelet, or a personal accessory such as a hat, a hair band, gloves, and shoes. It may be configured as a unit.

[0217] By constituting as a part of accessories and accessories, the portability is greatly improved as in the case of the above-mentioned digital timepiece, and the parent device 1 'and the child device 2' can be carried without discomfort. Therefore, it is possible to prevent a situation in which the user forgets to carry the parent device 1 ′ and the child device 2 ′ and cannot perform the original functions.

The above-mentioned master unit 1 'and slave unit 2' may have the same or similar shape and design as each other. For example, master unit 1 'is a pendant type, and slave unit 2' is a ring. They may have different shapes and designs, such as a mold (or vice versa). (D) Description of Fourth Embodiment FIG. 24 is a schematic diagram showing the configuration of a parent-child distance response type alarm generation device as a fourth embodiment of the present invention. , 2'-1 to 2'-N (N is 2

In this case, for example, the button 6C (6D-i) is mainly used for turning on / off the power, the button 7C (7D-i) is used for changing the setting of the distance / reaction direction mode, and the button 9C is mainly used for turning on the alarm output. Assume that it is used for / OFF.

That is, the alarm generator of the fourth embodiment is similar to the base unit 1'-
1 and a plurality of slave units 2'-i similar to those described above in the third embodiment. However, in this case, the master unit 1'-
1, the signal received from the child device 2'-i is
-A function is required to identify whether the message comes from i.

In the fourth embodiment, for example, FIG.
As shown in FIG. 4, the frequency of the signal (radio wave) transmitted by the slave unit 2'-i is changed for each slave unit 2'-i as f _i ', and the master unit 1'-1 receives the frequency. The signal frequency f _i ′
Can identify which slave unit 2'-i the signal is from. For this reason, the parent machine 1 'of the fourth embodiment.
For example, as shown in FIG. 25, -1 includes a control unit 13 ', drivers 14' and 15 'similar to those described in the third embodiment, and an antenna 121,

[0238]

As described in detail above, according to the present invention (claim 1), the (first) portable timepiece as the master unit and the (second) portable timepiece as the slave unit are provided. 2) In each of the portable timepieces, a transmitter / receiver is provided, and a distance determining means for determining a clock distance and an alarm generating means for generating an alarm in accordance with the clock distance determined by the distance determining means. Since it is provided, there are the following advantages.

Since both the master unit and the slave unit generate an alarm in accordance with the clock distance between each other, both the master carrier and the slave unit can recognize each other's distance,
On the other hand, it is possible to reliably prevent a child (especially, a child of the child device) from getting lost or not being able to find it. Not only the base unit but also the slave unit generates an alarm, so that the person carrying the base unit can easily recognize even the current position of the person carrying the child unit, and more reliably, Can be prevented from getting lost or not being discovered.

When the slave unit is attached to luggage or the like, an alarm is generated not only for the master unit but also for the slave unit according to the distance to the luggage. It can easily recognize not only the distance to the location but also the position of the luggage, so that it is possible to more securely prevent misplacement or theft of luggage compared to the case where only the base unit issues an alarm,
Luggage can be detected.

Since both the master unit and the slave unit are configured as portable watches, they are excellent in portability and can be carried without discomfort. For example, a child or an elderly person carries the slave unit (or places the slave unit in a luggage). It is possible to significantly reduce the possibility that the above-mentioned functions cannot be performed due to forgetting to attach) or the accompanying person forgetting to carry the parent device.

Here, if the alarm generation means is configured to generate an alarm when the distance determination means determines that the clock-to-clock distance is greater than a certain (first) set distance, the alarm is generated. If the distance is longer than the above (first) set distance, both the master unit and the slave unit generate an alarm, so that
It is possible to prevent a lost child or misplaced luggage or theft (claim 2).

On the other hand, if the alarm generation means is configured to generate an alarm when the distance determination means determines that the clockwise distance is smaller than a certain (second) set distance,
When the clock distance is shorter than the above (second) set distance,
Since both the parent device and the child device generate an alarm, it is possible to surely detect and find the person carrying the child device (which may be a baggage) (claim 3).

In the case where each of the master unit and the slave unit is configured as a digital clock, the above-mentioned alarm generation means
If an alarm is generated based on the result of adding the time information of the digital clock (reference time pulse generation unit) to the information on the clock distance, the alarm can be generated simply without a warning based on the distance between the clocks. Since an alarm can be generated in consideration of (timekeeping information), it is possible to realize various types of alarm generation in consideration of time (claim 4).

For example, if an alarm is issued when the state where the clock-to-clock distance is larger (or smaller) than a certain set distance continues for a certain set time, once the clock-to-clock distance becomes equal to the above-mentioned set distance. Larger (or smaller) than
However, if the clock distance falls within the above set distance (or outside the set distance) within the above set time, no alarm is issued. Alarm can be prevented from being generated, whereby discomfort due to frequent alarm generation can be reduced, and power consumption of the master unit and the slave unit can be reduced. 5, 7).

If the master unit and the slave unit are provided with a set time changing means for varying the set time, the set time can be appropriately changed according to the purpose of use of the present apparatus. Therefore, it greatly contributes to the improvement of flexibility in use of the present apparatus (claims 6 and 8). The alarm generating means generates an alarm when the clock distance becomes larger than a certain (fifth) set distance, and generates an alarm when the clock distance becomes smaller than a certain (sixth) set distance smaller than the set distance. May be stopped. In this case, after the distance between each of the master unit and each of the slave units becomes greater than (or away from) the fifth set distance, the alarm will continue to be generated unless the respective units are closer to each other than the sixth set distance. Therefore, it is possible to more reliably prevent a lost child, misplaced luggage, or theft (claim 9). Conversely, the alarm generation means generates an alarm when the clock-to-clock distance becomes smaller than a certain (seventh) set distance, and a certain (eighth) smaller than the set distance.
The alarm may be stopped when the distance exceeds the set distance. In this case, after the distance between each of the master unit and each of the slave units becomes smaller than (approached to) the seventh set distance, the alarm continues to be generated unless the respective sets are separated from each other by more than the eighth set distance. Therefore, the detection sensitivity of the portable device (including luggage) of the child device is greatly improved (claim 10).

The master unit and the slave unit may each be provided with a clock-distance setting changing means for changing the set value of the clock-distance as a reference for generating an alarm. Since the set value of the clock distance as a reference for generating an alarm can be appropriately changed according to the above, it greatly contributes to improvement in flexibility in use of the present apparatus (claim 11).

Further, the master unit (first portable timepiece) is provided with an alarm generation inhibiting means for inhibiting the generation of an alarm since at least the slave unit (second portable timepiece) generates an alarm. Thereby, it is possible to prevent a warning from being issued for the base unit when it is not necessary, and to reduce power consumption.
2).

Further, the alarm generating means of the slave unit (second portable timepiece) is adapted to generate an alarm after a lapse of a predetermined time from the reference time specified by the master unit, or to set the alarm at the reference time specified by the master unit. The alarm may be generated at predetermined time intervals from, so that, for example, the carrier of the child device can recognize the time to return to the person of the parent device. It is possible to more reliably prevent the child from getting lost or missing. Further, when the slave unit is attached to a luggage or the like, it is possible to recognize the time when the luggage or the like should be carried, so that it is possible to more reliably prevent the luggage from being left or stolen. , 14).

In this case, in this case, the master unit (first portable watch)
If the alarm generating means is configured to generate an alarm in response to an alarm from the slave (second portable watch), the master also generates an alarm at the same timing as the slave, so that the Even if the distance is long, for example, the carrier of the parent device can recognize the time to pick up the carrier of the child device (time to carry the luggage), and more surely get lost or missing (misplaced luggage). And theft) can be reduced (claim 15).

Next, according to the parent-child distance response type alarm generation device of the present invention (claim 16), even when there are a plurality of (fourth) portable watches as child devices, the child device is By providing clock identification means for identifying which slave unit the signal from the unit is from, the slave unit identified by the clock identification unit is connected to the master unit in accordance with the clock distance in the same manner as described above. The following advantages are obtained because both the slave units generate the alarm.

Even when there are a plurality of handset carriers, it is possible to reliably prevent all the handset carriers from getting lost or not being found. Since the slave unit also generates an alarm, the carrier of the master unit can easily recognize which slave unit carrier is currently located where. It is possible to prevent getting lost or being unable to be found.

When the child device is attached to a plurality of luggage or the like, the carrier of the parent device (owner of the luggage) can easily recognize which luggage is where. It can prevent misplacement or theft of all luggage and detect luggage. Also in this case, since both the parent device and the child device are configured as portable watches, they are excellent in portability and can be carried without discomfort. For example, a child or an elderly person carries the child device (or carries the child device Can be greatly reduced.

Further, according to the parent-child distance response type alarm generating device of the present invention (claim 17), even if the parent device and the child device are not each configured as a portable timepiece, the distance determination means and the alarm are respectively provided. Since there is a generating means,
As with the above-described device (claim 1), the following advantages are obtained. Since both the parent device and the child device generate an alarm according to the distance from each other, both the parent device carrier and the child device carrier can recognize each other's distance. It is possible to reliably prevent the person carrying the device from getting lost or not being able to find it.

Since not only the parent device but also the child device generates an alarm, the person carrying the parent device can easily recognize even the current position of the person carrying the child device. Can be prevented from being lost or not found. If the slave unit is attached to luggage, etc., not only the base unit but also the slave unit will generate an alarm according to the distance to the luggage,
The carrier of the parent device (owner of the luggage) can easily recognize not only the distance to the luggage but also the position of the luggage, which is more reliable than when only the parent device issues an alarm. In addition, it is possible to prevent misplaced or stolen luggage and detect luggage.

Further, according to the distance-between-parent-child alarm generating device of the present invention (claim 18), when the master unit and the slave unit are not configured as portable watches, and when there are a plurality of slave units, However, by providing the parent device with a child device identification means for identifying a signal from the child device from which child device, for the child device identified by the child device identification means, as described above, Since both the master unit and the slave unit generate an alarm according to the distance between the clocks, the following advantages can be obtained as in the case of the above-described device (claim 16).

Even when there are a plurality of handset carriers, it is possible to reliably prevent all of the handset carriers from getting lost or not being able to be found. Since the slave unit also generates an alarm, the carrier of the master unit can easily recognize which slave unit carrier is currently located where. It is possible to prevent getting lost or being unable to be found.

When the child device is attached to a plurality of luggage or the like, the carrier of the parent device (owner of the luggage) can easily recognize which luggage is located where. In addition, it is possible to prevent misplacement or theft of all luggage, and to detect luggage.
