DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a self-sounding anti-theft tag attached to an object such as clothing and footwear, and issuing an alarm by itself to prevent the object from being stolen.

[0002]

2. Description of the Related Art FIGS. 8 and 9 are explanatory views for explaining a use state of a conventional self-sounding anti-theft tag.
0 is a strip-shaped anti-theft tag. On the front of the anti-theft tag 100, a button 102 of a button switch which is a normally open contact is provided.
LED protruding from the corner of the anti-theft tag 100
There is provided a light emitting unit 105 having a built-in. Anti-theft tag 100
By pressing the button 102 into the anti-theft tag 100 and closing the front surface by facing the front surface of the object T such as a box and a case which is to be prevented from being stolen, and pressing the button 102 into the anti-theft tag, It is attached to the object T by an attachment material 110 such as a synthetic resin wrap, an adhesive tape or a double-sided tape.

The anti-theft tag 100 also has a receiving circuit for receiving a signal transmitted from a transmitter, a buzzer, a battery, and the like. The transmitter is designed to transmit a signal of a strength that can be received by the anti-theft tag 100 into a predetermined monitoring area, and the transmitter is arranged at a gate installed at the entrance. When the object T with the anti-theft tag 100 approaches the gate and the anti-theft tag 100 receives the signal transmitted from the transmitter, the anti-theft tag 100 activates a buzzer, emits an alarm sound and emits light. The part 105 is blinked to prevent the object T from being stolen.

When the attachment member 110 is removed and the anti-theft tag 100 is removed from the object T, the button 102
The anti-theft tag 100 detects this because it protrudes and opens the circuit, activates the buzzer, emits an alarm sound, and emits light.
Flashes 105.

[0005]

Although the self-sounding anti-theft tag has a structure in which the built-in battery is not replaced, a circuit is designed so that the life of the anti-theft tag is 10 years or more. The predetermined period shorter than the design life is defined as the warranty period. When the warranty period is determined, an advance time for the alarm operation with a large power consumption is assumed in advance, but if the cumulative operation time of the alarm operation of the shipped anti-theft tag becomes longer than the estimated time, the anti-theft operation is performed. The life of the tag comes within the warranty period.

In a conventional anti-theft tag, the light emitting unit 10
It was possible to judge intuitively the consumption of the built-in battery by the decrease in the light emission intensity and the decrease in the volume of the alarm sound. However, since such a determination is inaccurate, the anti-theft tag may be used in spite of the relatively short life expectancy of the anti-theft tag, and the anti-theft tag may reach the end of its life when attached to an object. Was.

FIG. 4 is a schematic partially enlarged side sectional view of the anti-theft tag shown in FIG. The printed wiring board 10 is supported by the housing 1 with the back face facing the front box member 2 and a slight gap between the board 10 and the front box member 2. On the surface of the substrate 10, a microcomputer 11 and a battery 12 are mounted. An inspection terminal 16 protrudes from a portion of the rear surface of the substrate 10 opposite to the detection opening 13 provided in the front box member 2. The inspection terminal 16 is electrically connected to the battery 12. Connected.

In such an anti-theft tag, when the leg 45 of the pin 40 is not inserted into the insertion hole 2e, a probe connected to a detector such as a voltmeter is connected to both detection openings 13, 13.
Then, the battery 12 is inserted into the inspection terminal 16 (16) so as to make contact with the inspection terminal 16 (16), thereby detecting the voltage of the battery 12 and accurately determining the degree of consumption of the battery 12. On the other hand, when the anti-theft tag is attached to the target object by inserting the leg 45 of the pin 40 into the insertion hole 2e, the detection openings 13, 13 are closed by the head 47 of the pin 40 and the target object. Inspection terminal 16
It becomes impossible to operate (16).

(Embodiment 3) FIG. 5 is an external perspective view showing an anti-theft tag according to Embodiment 3 and shows a case where a wire 30 is used as an attachment. FIG. 6 is an enlarged partial rear sectional view of the anti-theft tag shown in FIG. The wire 30 has connecting portions 31, 31 each formed by covering a conductive pin-shaped member with an insulating material except for the tip thereof, with a connecting portion 33 having a conductive wire covered with an insulating material. In the figure, parts corresponding to the parts shown in FIG. 1 are denoted by the same reference numerals, and description thereof is omitted.

Two insertion holes 9, 9 into which both insertion portions 31, 31 of the wire 30 are separately inserted are provided on one end surface of the rectangular casing 1.
And a jack 18 for locking both insertion portions 31, 31 of the wire 30 inserted into the insertion holes 9, 9, is provided at a position in the housing 1 opposite to the insertion holes 9, 9. It is. A knob 7 of a release slider 8 for unlocking the insertion portion 31 inserted into one insertion hole 9 is slidably provided on the side surface of the housing 1.

In order to attach such an anti-theft tag to an object, one insertion part 31 of the wire 30 is inserted into the other insertion hole 9 until it is locked by the jack 18, and the shirt as the object is inserted. After inserting the other insertion part 31 of the wire 30 through the button hole or the stitch of the knit product as the object and hanging the connecting part 33 around the object, the other insertion part 31 is connected to the one insertion hole. Insert it into 9 until it is locked by jack 18.

In the housing 1, there are provided a receiving circuit for receiving a predetermined signal, a battery, a buzzer for generating an alarm sound, a microcomputer for controlling the operation of the buzzer, and the like. The aforementioned wire 30 functions as a normally closed contact, and the microcomputer does not receive the reception signal related to the reset signal from the receiving circuit, and inserts the insertion portions 31 and 31 of the wire 30.
When the connection between the two insertion holes 9 and 9 into which the is inserted becomes non-conductive, the buzzer is activated to prevent the object from being stolen. Also, when an object to which the anti-theft tag is attached approaches the gate, the receiving circuit of the anti-theft tag receives a signal transmitted from a transmitter disposed at the gate, and gives a received signal to the microcomputer. The microcomputer operates a buzzer to generate an alarm sound.
