Abstract

PROBLEM TO BE SOLVED: To prevent a stolen canceller from being abused without requiring any complicated work by providing a burglar preventing tag equipment with a control means for comparing a canceller abuser preventing ID set in a signal generator with a canceller abuse preventing ID set in the canceller, and when both ID data are not matched with each other, inhibiting the cancel of robbery monitoring for a commodity to which a crime prevention tag is attached by the canceller. SOLUTION: The canceller abuse preventing ID newly selected/set by an antenna controller part 11 is read out from a signal outputted from a ceiling antenna part 9 and the read ID is compared with the canceller abuse preventing ID set on a canceller 7. When both the ID data are not matched with each other, the canceller 7 is turned to a stop mode and can not be functioned. Since the new canceller abuse preventing ID is changed by the antenna controller part 11, non-coincidence of both the ID is normally detected and the canceller 7 is turned to the stop mode. Consequently the abuse of the stolen canceller 7 can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a security tag including a security tag attached to each product, a release device used for removing the security tag from the product, a signal generator for transmitting a signal to the release device, and the like. The present invention relates to a tag device, and more particularly to a device devised so that when a release device is stolen, a measure for preventing its abuse can be easily performed.

[0002]

2. Description of the Related Art Security tag equipment is generally configured as follows. First, a security tag, for example, a self-sounding security tag is attached to each product. And a third party, for example,
If you attempt to steal the product with the self-sounding security tag attached, when you pass through a predetermined entrance of the store, the self-sounding alarm signal output from the separately installed antenna Ring the security tag, thereby notifying the theft. Also, if you want to forcibly remove the self-sounding security tag from the product (specifically, cut or break the string attached to the product with the self-sounding security tag), The self-sounding security tag sounds when the cord is cut or broken, thereby notifying the occurrence of theft.

On the other hand, there is a release device, which is used, for example, when a self-sounding security tag attached to a product is replaced with another product, and is mounted on the product. By inserting the self-sounding security tag into the unlocking device, it is possible to remove the self-sounding security tag from the product without outputting an alarm. Then, the self-sounding security tag once removed from the product is attached to another product.

[0004] In the security tag equipment having such a configuration, for example, it is expected that a third party will steal and abuse the unlocking device. For example, in a plurality of affiliated stores, it is common to employ security tag equipment of the same system, so that a store can be stolen from an arbitrary store and used at another store to abuse it. It is expected that the ring-type security tag is detached from the product and the product is stolen.

[0005] In order to solve such a problem, for example, systems as described in JP-A-9-259368 and JP-A-9-267859 have been proposed. The systems disclosed therein include a plurality of I-type security tags, a release device, and a plurality of I
Hold D. When used, an arbitrary ID is selected and set from the plurality of IDs. In this case, the security tag, the unlocking device, and the antenna are set to the same selected ID.

If the unlocking device is stolen, the ID of the self-sounding security tag and the antenna are changed to different IDs. As a result, even if an attempt is made to release the self-sounding security tag from the product using the stolen unlocking device, the ID cannot be changed because the ID has already been changed, and the product cannot be stolen. That is. or,
In another system, when a third party approaches the gate in an attempt to steal the unlocking device, the unlocking device sounds, thereby preventing theft itself of the unlocking device.

[0007]

According to the above-mentioned conventional configuration, there are the following problems. First, in the case of changing the ID when the unlocking device is stolen, there is a problem that an extremely complicated operation is required. That is, security tags are individually attached to an enormous number of products, and it is necessary to perform processing to change the ID for all of the enormous number of security tags. is there. In addition, in the case of a system in which a ring is sounded when approaching the gate in order to steal the unlocking device, the alarm sounds even when a regular employee carries the unlocking device and approaches the gate. There was a problem that usability was poor in a sense.

The present invention has been made on the basis of the above points, and it is an object of the present invention to provide a security tag capable of preventing an abuse when the unlocking device is stolen without requiring a complicated operation. To provide facilities.

[0009]

To achieve the above object, a security tag device according to claim 1 of the present invention is provided with a security tag detachably attached to a product displayed in a store and monitoring theft of the product. In a security tag equipment comprising a release device for releasing the monitoring of the theft of the security tag for the product and a signal generator for transmitting a signal to the release device, the security tag device is provided on the release device and optionally provided in advance. Canceler abuse prevention ID setting means on the canceler side for setting a canceler abuse prevention ID indicating the ID of the canceller which can be set in the signal generator;
A canceller abuse prevention ID setting means on the transmission side for setting D;
The canceler abuse prevention ID set on the signal generator side provided in the canceller is compared with the canceller abuse prevention ID set on the canceller side. And control means for prohibiting the security tag from being monitored for theft of the product by the security tag. Further, the security tag equipment according to claim 2 is the security tag equipment according to claim 1, wherein the ID for preventing the abuse of the unlocking device, which is provided in the unlocking device and set on the signal generating device side, is set on the unlocking device side. And control means for permitting release of monitoring of the theft of the security tag by the release tag by the release device in the event of a match if the ID is compared with the release device abuse prevention ID. It is. The security tag equipment according to claim 3 is the security tag equipment according to claim 1 or 2, wherein the signal generating device is an antenna that outputs an alarm command signal for outputting an alarm to the security tag. It is a feature.

That is, the security tag equipment according to the present invention comprises:
The canceler compares the canceler abuse prevention ID on the signal generator side with the canceler abuse prevention ID on the canceler side, and when the two canceler abuse prevention IDs do not match, monitors for theft of the security tag by the canceler by the canceller. For example, a person who attempts to abuse the unlocking device can detect theft of the unlocking device or enter another store or notice that the unlocking device is stolen. If a security device is used by invading the place where the setting of the means has been changed and the security device abuse prevention ID does not match, the function to release the monitoring of the security tag for theft is prohibited. When the occurrence of the theft is detected and an alarm or the like is output, the security tag does not function as the unlocking device even if the unlocking device is used, and the security tag continues to output an alarm to prevent theft. Further, the security tag equipment according to the present invention is characterized in that, in the release device, the release device abuse prevention ID on the signal generator side and the release device abuse prevention ID on the release device side
In the case where the two unlocking devices have the same ID, the control device for permitting the unlocking device to cancel the monitoring of theft of the security tag by the product is provided. It can be used, of course, even if you accidentally bring the unlocker to another store where a different unlocker abuse prevention ID is transmitted, the same as the unlocker abuse prevention ID set in the unlocker again When the canceler is brought into the store to which the canceler abuse prevention ID is transmitted, that is, brought back to the own store, the canceler can be used again as the canceler. In addition, since the security tag equipment according to the present invention is an antenna that outputs an alarm command signal for outputting an alarm to the security tag, a signal for transmitting a new canceler abuse prevention ID in addition to the antenna installed for the security tag. There is no need to install a generator, and unauthorized use of the canceller can be prevented.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. FIG. 1 is a diagram showing a schematic configuration of the whole security tag equipment according to the present embodiment. First, there is a self-sounding security tag 1. The self-sounding security tag 1 is individually attached to each product (not shown) via a cord 3. The string body 3 has both ends attached to a case 5. In the case 5, a power supply unit, an alarm unit, a control unit, a switch for issuing an alarm, and the like are provided.

Further, there is a canceller 7. For example, when the self-sounding security tag 1 is replaced with another product, the self-sounding security device can be used without outputting an alarm by using the canceler 7. Unlock the tag 1 for the product. Further, there is a ceiling antenna section 9 as an antenna, and this ceiling antenna section 9 is mounted at a predetermined ceiling position in a store. An antenna controller 11 is connected to the ceiling antenna 9.

Hereinafter, the release unit 7, the ceiling antenna unit 9,
The configuration of the antenna controller 11 will be described in detail.
First, the ceiling antenna section 9 and the antenna controller section 11 are configured as shown in the block diagram of FIG. The ceiling antenna section 9 has a transmission coil 13. Further, the antenna controller 11, a central processing unit 15, transmission output control circuit 17, DIPSW ₁ 1
9, DIPSW ₂ 21 is disposed. When the antenna controller 11 is viewed from the front, the antenna controller 11 is as shown in FIG. 3, in which the DIPSW ₁₁ described above is included.
9, DIPSW ₂ 21 are arranged in a layout as shown. Although other components are shown in FIG. 3, they are not denoted by reference numerals for the sake of explanation.

[0014] The DIPSW ₁ 19 is, "alarm I
D ₁ ”and“ alarm ID ₂ ”. That is, an alarm command signal is output from the ceiling antenna unit 9 within a predetermined communicable area. That is, if the user attempts to steal while the self-sounding security tag 1 is attached to the product, the tag must pass through the communicable area of the ceiling antenna unit 9.
Then, when passing through, the self-sounding security tag 1 outputs an alarm by receiving an alarm command signal of the ceiling antenna unit 9, thereby notifying the occurrence of theft of the product. I have to. The above "Alarm I
D ₁ ”and“ alarm ID ₂ ”are for outputting the alarm command signal. Then, the above-mentioned DIPSW ₁ 19 is,
As shown in Table 1 below, three "on / off switching units" are provided.

[0015]

[Table 1]

Each of the "on / off switching units"
For example, two types of set values can be set by selecting and combining the ON and OFF of. still,
From the ceiling antenna 9, these two “Alarm I
D ₁ ", which is one selected and set among the" Alarm ID ₂ "I
D outputs an alarm command signal. or,
FIG. 10 shows demodulated signals when the self-sounding security tag 1 receives the respective alarm command signals of “Alarm ID ₁ ” and “Alarm ID ₂ ”. The difference between “alarm ID ₁ ” and “alarm ID ₂ ” is that the intervals of the waveforms constituting the signal are different.

Meanwhile, although a DIPSW 2 _21, which is intended to be used to set the de-preventing abuse ID, as shown in the following Table 2, in this embodiment, six By selecting and combining each on / off using the "on / off switching unit" of
Sixty-four types of set values can be set, and these are used as a canceller abuse prevention ID. Specifically, an arbitrary one of the canceller abuse prevention IDs is selected and set from the 64 types of canceler abuse prevention IDs.

[0018]

[Table 2]

The radio wave output from the transmission coil 13 of the ceiling antenna unit 9 will be described. The self-sounding security tag 1 already described is provided with the transmission coil 13 of the ceiling antenna 9.
It is configured to detect the fall and the period of the radio wave output from. Therefore, when outputting the canceller abuse prevention ID by radio wave, only the "ON" time is appropriately changed in each pulse of the radio wave conventionally used, and the cycle is the same. It is shown in FIG. The left side in FIG. 4 is a state of “1” (DIPSW ₂
21 ON / OFF switching section is ON), and the right side is “0”
A state (DIPSW ₂ 21 on and off switching unit is off of).

The transmission coil 1 of the conventional ceiling antenna 9
3 is output in such a manner that ID information for canceling the abuse of the canceller is added to the alarm issuing signal output from 3. This is shown in FIG.

Next, the configuration of the canceller 7 will be described. As shown in the block diagram of FIG. 2, the canceller 7 includes a central processing unit 31, a receiving coil 33, an alarm radio wave receiving circuit 35, a canceling SW 37, a DIPSW 39, a canceling radio wave transmitting circuit 41, and a transmitting coil 43. As shown in FIG. 6, there is a case 45.
5 is inside. In addition, an insertion space 47 for inserting the self-sounding security tag 1 is formed in the case 45 (the self-sounding security tag 1 inserted in FIG. 7 is indicated by a virtual line). Alarm release SW at predetermined position
49 are attached. A battery 51 is provided inside the case 45, and LEDs 53 and 55 are arranged on the surface of the case 45.

The release SW 37 and the alarm release SW 49 will be described briefly. First, the release SW 37 is
By operating this, the self-sounding security tag 1 that is currently outputting an alarm is to stop the alarm output. On the other hand, the alarm release SW 49 is for stopping the alarm output function of the self-sounding security tag 1. For example, when attaching the self-sounding security tag 1 attached to an arbitrary product to another product, the self-sounding security tag 1 is inserted into the insertion space 47 of the unlocking device 7. As a result, the alarm release SW 49 is pressed, whereby the alarm output function of the self-sounding security tag is stopped.
Thereafter, by further inserting the self-sounding security tag 1 into the insertion space 47, the locked state of the product with the self-sounding security tag 1 is released. That is, it is possible to release the locked state of the self-sounding security tag 1 for a product without outputting an alarm, thereby enabling replacement with another product.

DIPSW provided in the canceller 7
39 will be described. As shown in the following Tables 3 and 4, the DIPSW 39 includes eight “on / off switching units”.
It has. Among them, as shown in Table 3, by selecting either ON / OFF of the third “ON / OFF switching unit”, one of “release ID ₁ ” and “release ID ₂ ” is selected. Set. That is, as described above, the canceling device 7 outputs an alarm canceling signal to the self-sounding security tag 1 (the canceling SW 37 described above).
Is output by the operation of the above), and the above-mentioned "cancel ID ₁ " and "cancel ID ₂ " are selected to output this alarm cancel signal.
It is set.

[0024]

[Table 3]

[0025]

[Table 4]

Separately, the canceler abuse prevention ID is set using the fourth "on / off switching section" to the eighth "on / off switching section".
That is, a total of 64 types of canceller abuse prevention IDs are set by appropriately selecting and combining on / off of the fourth “on / off switching unit” to the eighth “on / off switching unit”. Any one of the canceler abuse prevention IDs is selected and set.
As a matter of course, in a normal use condition,
Selection / selection on the antenna controller 11 side already described
The same canceler abuse prevention ID as the set canceler abuse prevention ID
Will be selected and set.

The operation will be described based on the above configuration. First, in use of the security tag equipment, the antenna controller 11 side, "Alarm ID _1" using DIPSW ₁ 19, to select and set one of "Alarm ID _2". At the same time, the DIPSW ₂ 21, to select and set any one decompressor preventing abuse ID from among 64 types of de-preventing abuse ID.

Next, also on the release unit 7 side, the DIPSW
Using 39, the same canceller abuse prevention ID as the canceler abuse prevention ID selected and set by the antenna controller section 11 is selected and set from the 64 types of canceller abuse prevention IDs. In this state, the release unit 7 is brought into the communicable area of the ceiling antenna unit 9, and I
Obtain D information.

At this time, the canceler abuse prevention ID selected and set by the antenna controller 11 and the canceler abuse prevention ID selected and set by the canceler 7 coincide with each other. Enter operation mode. In this operation mode, the canceler 7 can cancel the monitoring of the product by the self-sounding security tag 1, and can stop the alarm output by the cancel SW 37 and the alarm output function by the alarm cancel SW 49. At this time, if the canceler abuse prevention ID selected and set by the antenna controller unit 11 and the canceler abuse prevention ID selected and set by the canceler 7 do not match, the canceler 7 Becomes the stop mode. In this stop mode, the release device 7 is prohibited from releasing the monitoring of the product by the self-sounding security tag 1, and the release SW 37
And the alarm output function by the alarm canceling SW 49 is not stopped. In order to set the canceller 7 from the stop mode to the operation mode again, the DI on the canceler 7 side
This can be achieved by using the PSW 39 to change the canceler abuse prevention ID that is the same as the canceler abuse prevention ID selected and set by the antenna controller section 11 and to obtain the ID information again. Also, D on the side of the antenna controller
Use IPSW 2 _21, change in the same de-preventing abuse ID and de-preventing abuse ID selected and set by de-7 side, decompressor if caused to acquire the ID information to the decompressor 7 again 7
Can be set to the operation mode. When the canceler abuse prevention ID of the antenna controller 11 is changed,
In addition, it is necessary to change the canceler abuse prevention ID of all the cancellers 7 used in plural.

Next, a case where the unlocking device 7 set as described above is stolen will be described. In this case, in the antenna controller 11 and the new canceller 7,
A canceler abuse prevention ID different from the canceler abuse prevention ID previously selected and set from among 63 types of canceller abuse prevention IDs is newly selected and set. The selection / setting operation is as described above. Incidentally, no change work is performed on the self-sounding security tag 1 used in large numbers.

In this state, when a third party carries the stolen unlocking device 7 to steal the merchandise and enters the store, and enters the communicable area of the ceiling antenna section 9, the central processing of the unlocking device 7 is performed. The following processing is executed in the unit 31. That is, the canceler abuse prevention ID newly selected and set by the antenna controller section 11 is read from the signal output from the ceiling antenna section 9, and the read canceller abuse prevention ID and the release of the canceller 7 side are read. It is compared with the device abuse prevention ID to determine the match / mismatch.

The canceler abuse prevention ID output from the ceiling antenna unit 9 and the canceller abuse prevention ID on the canceler 7 side
, The canceler 7 enters the operation mode. On the other hand, when the canceler abuse prevention ID output from the ceiling antenna unit 9 does not match the canceler abuse prevention ID on the canceler 7 side, the canceler 7 enters the stop mode and does not function. In this case, after the release device 7 is stolen, a new release device misuse prevention I
Since D has been changed, it usually becomes inconsistent and enters the stop mode. As a result, the stolen canceller 7 can be prevented from being misused.

Even if a third party who has stolen the releaser 7 changes the releaser abuse prevention ID on the releaser 7 side, as described above, there are 63 types of selection ranges (64). One unlocking device abuse prevention ID initially selected and set from the type
Therefore, the probability of coincidence is extremely low, and in that sense, the abuse of the canceller 7 can be prevented with an extremely high probability.

The above operation will be confirmed with reference to the flowchart of FIG. FIG. 9 shows the processing executed on the canceler 7 side. First, in step S1, the power is turned on, and then the process proceeds to step S2, in which the release function of the self-sounding security tag 1 is temporarily turned off. Next, the process proceeds to step S3, where it is determined whether a warning radio wave from the ceiling antenna unit 9 has been received. If the alarm radio wave has not been received, the determination in step S3 is repeated. On the other hand, if the alarm radio wave has been received, the process proceeds to step S4. In step S4, it is determined whether the canceler abuse prevention ID output from the ceiling antenna unit 9 matches the canceler abuse prevention ID on the canceler 7 side.

The canceler abuse prevention ID output from the ceiling antenna 9 and the canceler abuse prevention ID on the canceler 7 side
If they do not match, the process moves to step S2. That is, the tag release function of the canceller 7 remains off, and the canceler 7 enters the stop mode. On the other hand, if the canceler abuse prevention ID output from the ceiling antenna unit 9 matches the canceler abuse prevention ID on the canceler 7 side, step S
Move to 5. That is, the tag release function is turned on, and the release unit 7 enters the operation mode.

As described above, normally, the unlocking device abuse prevention ID of the stolen unlocking device 7 is initially set, and another new unlocking device abuse prevention ID is set on the antenna controller section 11 side. Since they have been selected and set, the results of the comparison will not match. Also, suppose the stolen unlocker 7
Even if a new canceller abuse prevention ID is selected and set on the side, since it is selected from a total of 63 types, it matches the canceller abuse prevention ID selected and set on the antenna controller unit 11 side The probability of doing this is extremely low. Therefore, the result of the comparison usually becomes inconsistent, and the canceller 7 enters the stop mode.

According to the present embodiment, the following effects can be obtained. First, when the unlocking device 7 is stolen, its abuse can be prevented beforehand, and at that time, complicated work is not required as in the related art. That is, in the antenna controller section 11 and the new unlocking device 7, it is only necessary to newly select and set the unlocking device abuse prevention ID, and the number of the self-sounding security tags 1 is changed without any change. Because it is good. or,
The number of de-preventing abuse ID that can be selected, the DIPSW ₂ 21 and de-7 side of the antenna controller 11 side D
This can be further increased by increasing the number of on / off switching units of the IPSW 39, thereby preventing the abuse of the canceller with a higher probability. Also, since an alarm is not output unnecessarily, the usability in a normal state is good.

The present invention is not limited to the above embodiment. First, in the one embodiment,
If the stolen unlocker is brought into the store and does not match the unlocker abuse prevention ID newly selected and set by the antenna controller unit 11, it is set to the stop mode to prevent the abuse. In this case, an alarm may be output at the same time, so that a user who attempts to abuse the canceler can be notified. In this case, if an alarm is output in addition to the stop mode, it is possible to prevent the abuse and to notify the user of the fact that the abuse is attempted.

Alternatively, a configuration may be used in which the function of the canceler is lost by setting a timer. In this case, a special holder for holding the release unit when not in use is prepared, and the function is automatically lost when a preset time elapses after the release unit is separated from the special holder. Things. Therefore, if the unlocking device is stolen,
For abuse within the set time, canceler abuse prevention I
D can be prevented by changing it. Even if the canceller abuse prevention ID is not changed, the function can be automatically lost by exceeding the preset time. , Thereby preventing abuse. In this case, if a predetermined time elapses after the release device is released by the release device dedicated holder and the function is lost, it is possible to prevent the abuse with a higher probability. .

[0040]

As described in detail above, according to the security tag equipment of the present invention, it is possible to take an abuse prevention measure in the event that the unlocking device is stolen, without requiring a complicated change operation as in the prior art. This is because it is only necessary to change the canceler abuse prevention ID of the signal generator and the canceler abuse prevention ID of the new canceller, and it is not necessary to take any change procedure for the security tag used in large numbers. Also, even if the wrong ID of the canceler is different from the canceler by mistake,
When the same canceller abuse prevention ID as the canceler abuse prevention ID set in the canceler is received again, the canceler can be used as the canceler again, which is very convenient. In addition, no new equipment is required because the canceler abuse prevention ID is transmitted from the antenna that outputs an alarm command signal that causes the security tag to output an alarm. Also, since an alarm is not output unnecessarily, usability in a normal use condition is good.
