- the magnetic marker 10 of this embodiment is attached to a product 30 or the like, and the product 30 is monitored for unauthorized removal from a store or the like without completing accounting (payment of money). Used for The magnetic marker 10 is provided with a pair of diaphragms 15 and 16, a low coercivity magnet 20 with a vinyl coating 18, and a release paper 24. It is composed of adhesive tape22.
- a protrusion 12A is provided on the joint surface side of the upper case 12, and a recess 14A is provided on the joint surface side of the lower case 14.
- the protrusion 12A fits into the recess 14A, and the two cases 12 and 14 are joined together.
- the outer corner (top or corner) of the upper case 12 is rounded, the corner of the upper case 12 gets caught and the marker itself falls off the product, or the upper case 12 can be removed from the lower case 14. The inconvenience is avoided.
- Cases 12 and 14 are made of a hard material that does not easily dent when pressed with a finger. For example, PS (PS (PS)
- the low-coercivity magnets 20 with the diaphragm 15 and the 16 and vinyl coating 18 are accommodated, respectively.
- the vibration plates 15 and 16 are arranged in two stages so as to be substantially parallel to the thickness direction of the case 12. Then, when a driving signal is applied from the outside in a state where a bias magnetic field is applied by the low coercive force magnet 20, it is formed to a thickness of, for example, about 100 m from an amorphous material that vibrates magnetostrictively.
- the amorphous material for example, iron, cobalt, copper, niobium, boron, silicon and the like can be used.
- the vibration plate 15 disposed on the upper side has a curved shape, for example, forming a part of a circle having a diameter of about 50 mm, and the vibration plate 16 disposed on the lower side has a flat shape. . If the diaphragm 15 is also planar, it will contact or adhere to the lower diaphragm 16 and prevent good magnetostrictive vibration. By making it curved as shown, such contact It can also prevent adhesion S. On the other hand, the low coercive force magnet 20 is fixed inside the lower case 14 by ultrasonic bonding of the vinyl coating 18.

- the product 30 with the magnetic marker 10 attached is placed on the display shelf of the product. The buyer takes the item 30 from the display shelf and goes to the cashier to pay for it. When the cashier pays for the product 30, the cashier person degausses the low coercivity magnet 20 of the magnetic marker 10 with a demagnetizer (not shown).
- the low coercive force magnet 20 is demagnetized even if it passes through a detection gate (not shown), so that the vibration plates 15 and 16 in the case 12 are magnetostricted. Does not vibrate. Therefore, no alarm is given.
- the product 30 is taken out of the store without paying for the product 30, the product 30 passes through the detection gate without the demagnetization of the low coercive force magnet 20 by the cashier. Will do. Then, the detection signal output from the detection gate causes magnetostrictive vibration in the pair of diaphragms 15 and 16 of the magnetic marker 10, which is detected by the detection gate, generates an alarm sound, and turns on the warning light Will be done. As a result, the unauthorized removal of the product 30 is informed to the surroundings.
- the magnetic element is protected by a hard case. For this reason, Sufficient strength can be obtained, and even if pressed strongly from the outside, magnetostrictive vibration is generated reliably and an alarm is given.
- magnetostriction vibration is surely generated. Therefore, it is possible to use a low coercive force magnet as the magnet 20 for forming the bias magnetic field, and it is possible to sufficiently demagnetize the low coercive force magnet 20 while preventing malfunction.
- the magnetostrictive vibration is surely generated, it is possible to urge the generation of an alarm when illegally taking out.
- the magnetic marker 10 can be easily assembled and attached to the product 30 by using the double-sided adhesive tape 22.
- the magnetic marker 100 of this embodiment is further provided with a case 200 below the case 14 of the first embodiment, and an IC is formed in a space formed between these cases 14 and 200.
- a tag (wireless tag) 202 and its antenna 204 are provided.
- the cases are joined by the protrusions 12A and the recesses 14A, but in this embodiment, the cases are joined by ultrasonic welding.
- the IC tag 202 is accommodated in the magnetic marker 100, both can be attached to the product 30 at the same time.
- an IC tag there are a read-only type, a write-once type, and a rewritable type.
- the shoplifting prevention function similar to that of the magnetic marker of the present invention can be obtained by recording the data indicating that the payment at the cashier is completed on the IC tag.
- the gate for detecting the IC tag data is expensive.
- the gate that has been installed for shoplifting prevention can be used for ⁇ IJ. In other words, product monitoring using magnetic markers and product management using IC tags can be performed simultaneously.
- FIG. Figure 3 (A) shows the process of attaching an adhesive sheet to the magnetic marker case.
- a method of forming an adhesive sheet (adhesive tape and release paper) in a predetermined size in advance and affixing it to the case of the magnetic marker can be considered. Therefore, in this example, Fig. 3 (A ), A perforation 302 having a predetermined size is formed on the adhesive sheet 300 in advance. Then, the magnetic marker body 310 is pasted into each perforation 302.
- the magnetic marker body 310 When the magnetic marker body 310 is affixed in each perforation 302, it is as shown in FIG.
- the adhesive tape 22 When the magnetic marker main body 310 is peeled from the adhesive sheet 300 in this state, the adhesive tape 22 is cut along the perforation 3002, and the adhesive tape 22 is attached to the magnetic marker main body 310.
- the obtained magnetic marker is affixed to the product as shown in FIG. According to such a method, the interval between the perforations 302 can be suppressed to about 1 mm as shown in FIG. 3A, and waste of the adhesive sheet 300 can be eliminated.
- the magnetic marker does not cause magnetostrictive vibration unless it has a certain size in nature. However, if it is made larger than necessary, the material is wasted and the appearance of the product is worsened. Therefore, it is preferable to make it as small as possible under the condition that a desired magnetostrictive vibration is obtained. Under these conditions, in this embodiment, the magnetic marker body 310 has a length of 42 mm, a width of 11.5 mm, and a thickness of 1.4 mm. Since the adhesive sheet 300 is sufficiently thin, the thickness can be ignored.
