Description

  The present invention relates to a packaged product in which an article is packaged, and an unloading inspection system for inspecting an article or packaged product to be carried out.

  As a method for preventing unintentional removal of displayed products and displayed items, a method using an IC tag or a method using an LC oscillation circuit that resonates with a radio wave of a specific frequency Various security systems using these are proposed and implemented.

  On the other hand, since an IC tag and an LC resonance circuit are relatively conspicuous, a coil is formed on one surface of a transparent film, and a capacitor is formed by a pair of electrodes sandwiching the transparent film, so that an inconspicuous LC A proposal has been made to form an oscillation circuit (see, for example, Patent Document 1).

  In addition, a proposal has been made to prevent the shoplifting prevention wire from being conspicuous and prevent it from being removed from the product by winding the magnetic wire as the shoplifting prevention wire into the paper at regular intervals. (For example, refer to Patent Document 2).

  On the other hand, POS (Point of Sales) system has become common in merchandise sales, and by reading the bar code for merchandise identification affixed to merchandise with a bar code reader, it is possible to collect merchandise price as well as merchandise management. Clearing is made easy.

  As an automatic settlement system corresponding to such a POS system, a magnetic thin wire and a magnetic material for control are embedded in a barcode label, and a magnetic field generator for magnetizing the magnetic material for control is attached to a barcode reader. Thus, a proposal has been made to detect a product that has not been cleared at the exit gate (see Patent Document 3).

However, if the magnetic material for control is magnetized at the time of reading the barcode, the security function attached to the barcode will be damaged even if trying to return the product during the checkout, There arises a problem that the product cannot be returned. In other words, when the product whose barcode is read by the barcode reader is returned, the product that cannot be detected by the security gate will be displayed, and the possibility that it will be taken out unintentionally increases. Products that should be returned can be taken out.

  The present invention has been made in view of the above facts, and is a packaged product in which an article that can be surely prevented from being taken out unintentionally, and an operation that is easy and can ensure high security. The purpose is to propose a carry-out inspection system.

  In order to achieve the above object, a packaged product of the present invention packages an article with a packaging material in which a first magnetic material that emits a pulse-like response signal when an alternating magnetic field is applied is embedded in a predetermined portion. It is characterized by being.

  According to this invention, the first magnetic material is embedded in the packaging material, so that the first magnetic material cannot be removed from the packaged product.

  In the present invention, it is preferable that the first magnetic material is coated with a second magnetic material having a coercive force higher than that of the first magnetic material and embedded in the packaging material. It is more preferable that a code for specifying the article is formed at a site on the packaging material in which the first magnetic material is embedded.

  Furthermore, in the present invention, since a paper having a paper thickness of about 80 μm to 100 μm is usually used, it is more preferable that the first magnetic material is formed into a thin wire having a predetermined length with an outer diameter of 30 μm or less. In addition to preventing the first magnetic material embedded in the packaging material from conspicuous and not causing irregularities on the surface of the packaging material, not only the formation of a barcode etc. is facilitated, but also this outer diameter If the following magnetic materials are used, the magnetic material is incorporated in the paper pulp or base paper in advance in the paper production process, so that it can be produced at a low cost and in large quantities in terms of cost compared to other methods. When the paper thickness is more than the above, a thicker magnetic material can be used, but mass production is difficult, and extra steps such as inserting the magnetic material after the paper is produced and the associated costs are incurred. However, detection is easy.

  Further, the carry-out inspection system of the present invention is a packaging in which a first magnetic body having a low coercive force among two types of magnetic bodies having different coercive forces is covered and embedded with a second magnetic body having a high coercive force. A packaged product in which an article is packaged by a material, or an unloading inspection system for an article in which the first and second magnetic materials are embedded in an exterior, provided at an outlet of the packaged article or the article, Detection means for applying an alternating magnetic field when the packaged article or article passes, detecting a response signal generated by the first magnetic material with respect to the alternating magnetic field, and notification for notifying that the detection means has detected the response signal And a demagnetizing means for erasing a response signal of the first magnetic material with respect to the alternating magnetic field by magnetizing the second magnetic material, and the demagnetizing means. Demagnetizing the second magnetic material magnetized by the magnetizing means to enable the first magnetic material to respond to the alternating magnetic field, and to switch the operation of the demagnetizing means and the magnetizing means. And switching means.

  According to the present invention, when preventing the packaged article or the article from being taken out illegally depending on whether or not the first magnetic material is demagnetized, the magnetizing means is provided integrally with the demagnetizing means. In addition to demagnetization that prevents the magnetic material from being detected by the detection means, both magnetization that enables the detection means to detect the first magnetic material can be performed.

  Thereby, operation which returns the packaged goods and goods which were going to carry out can be performed easily.

  In the present invention, a code for identifying the packaged product or article is recorded on the first and second magnetic materials, and the code reading means is used when the packaged product or article is unloaded. When the code is read, the demagnetizing means, the magnetizing means, and the switching means are provided integrally with the code reading means.

  According to the present invention, demagnetization is possible when reading a barcode, and magnetization is possible. Thereby, the operation | work when returning the demagnetized packaged goods and articles | goods can be performed smoothly.

  In the present invention, it is preferable that the demagnetizing means operates when the code is read by the code reading means, and the first magnetic field is applied to the first magnetic field by applying an alternating magnetic field integrally with the demagnetizing means. It can include a detection means for confirmation that detects a response signal generated by the magnetic material and confirms whether or not the demagnetization means is demagnetized.

  As described above, according to the present invention, according to the present invention, it is possible to reliably prevent the packaged goods and articles from being taken out illegally, and it is very easy to process returned goods and the like. Effect.

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a schematic configuration of a carry-out inspection system 10 according to the present embodiment. The carry-out inspection system 10 includes an operation unit 12, a gate antenna 14, a warning light 16, and a controller 18 that controls the operation thereof. In addition, although the operation part 12, the gate antenna 14, and the warning light 16 can be provided in arbitrary numbers, here, one unit is shown as an example.

  In the present embodiment, as an example of carry-out inspection, when a customer purchases and takes out a product displayed in a store such as a supermarket, the presence or absence of illegal take-out is inspected. That is, it is a crime prevention system that prevents so-called shoplifting, etc., in which products that have not been paid for products are illegally taken out.

  FIG. 2 shows a main part of the store 20 such as a supermarket in which the carry-out inspection system 10 is provided. In the store 20, a checkout terminal 26 of the POS system 24 is provided at the checkout counter 22, so that the customer brings the desired product in the store 20 to the checkout counter 22 and clears the product price. It has become.

  The cashier terminal 26 is provided with a handy type bar code reader 28, and the store clerk reads the bar code attached to the product brought to the cashier counter 22 by the customer by the bar code reader 28. Aggregate product prices. Further, the customer can take out (take out) by paying the total price of the commodities.

  The register counter 22 is provided with an embedded bar code reader 28A, and the bar code reader 28A can read bar codes of products. Hereinafter, these bar codes are collectively referred to as bar code readers. This will be described as 28. Moreover, a conventionally well-known structure can be applied to such a POS system 24, and description of this embodiment will be omitted.

  In the store 20, a security gate 30 is provided at a customer exit serving as a carry-out exit, and the customer can pass through the security gate 30 and go out of the store. The security gate 30 can be applied with any configuration such as not providing a gate as long as the customer always passes when the customer goes out of the store. However, for the sake of clarity, a gate is formed here. Yes.

  In the carry-out inspection system 10, the gate antenna 14 and the warning light 16 are provided in the security gate 30, and in the carry-out inspection system 10, when a product that is likely to be taken out illegally is detected by the gate antenna 14, the warning light 16 is displayed. Lights up or flashes to inform the store clerk. Note that the notification method is not limited to this, and it may be performed by an alarm or voice, or may be displayed on a display provided in a preset place. A combination of notification means may be used.

  Here, first, the in-store merchandise to be inspected by the carry-out inspection system 10 in this embodiment will be described. FIG. 3A schematically shows a packaged product 32 as an example of a product. The packaged product 32 is formed with a packaging material 34 in a box shape, and an article is accommodated therein.

  In the packaged product 32, a barcode 36 for specifying an internal product is formed at a predetermined position on the outer surface, and the barcode 36 is read by a barcode reader 28.

  On the other hand, as shown in FIG. 3B, in the packaging material 34, a magnetic wire 38 serving as a first magnetic material and a strip-shaped magnetic strip 40 serving as a second magnetic material are embedded at predetermined positions. It is. The embedded position of the magnetic wire 38 and the magnetic band 40 is a position where the barcode 36 is formed. That is, in the packaging material 34, the bar code 36 is formed by being printed over the magnetic wire 38 and the magnetic band 40.

  The magnetic wire 38 is made of, for example, a magnetic material, and can be formed with an arbitrary wire diameter and length. When embedding in the packaging material 34 using paper, although depending on the paper thickness, When the thickness is about 80 μm, it is preferably 30 μm or less. This prevents the magnetic wire 38 from causing unevenness on the surface of the packaging material 34, and the magnetic wire 38 is embedded. Can be made unrecognizable.

  Further, the magnetic wire 38 only needs to have an outer diameter and a length that can be detected using the Barkhausen effect, and any length can be applied as long as it does not protrude greatly from the barcode 36. The required length can be shortened when the outer diameter is large compared to when the outer diameter is small, depending on the outer diameter of the magnetic wire 38.

  Furthermore, since the magnetic wire 38 is detected using the Barkhausen effect, any magnetic material having a relatively low coercive force, such as amorphous silicon made of Co—Fe—Ni—B—Si, can be used.

  The magnetic band 40 may be of a size that covers the magnetic wire 38, may be formed of a magnetic material in a band plate shape, and is formed in a substantially cylindrical shape so as to wrap the magnetic wire 38. May be.

  The magnetic band 40 is formed using a magnetic material having a higher coercive force than the magnetic wire 38. That is, the magnetic wire 38 and the magnetic band 40 are formed using magnetic materials having different coercive forces.

  Such a magnetic wire 38 and a magnetic band 40 can be formed, for example, by placing or covering a powdery magnetic material having a high coercive force on a magnetic linear material having a low coercive force.

  The magnetic wire 38 having a low coercive force has a substantially rectangular hysteresis loop. For example, when an alternating magnetic field as shown in FIG. 4A is applied, steep and sharp magnetization reversal occurs. The magnetic wire 38 generates a pulse-like response signal when magnetization reversal occurs at the magnetization reversal point HP as shown in FIG.

  By detecting this response signal, it can be determined that the magnetic wire 38 is embedded in the packing material 34.

  On the other hand, the magnetic band 40 having a high coercive force is magnetized by applying a strong magnetic field, and applies a bias magnetic field to the magnetic wire 38. When an alternating magnetic field is applied in a state where the magnetic band 40 is magnetized and a predetermined bias magnetic field is applied to the magnetic wire 38, the magnetization reversal of the magnetic wire 38 due to the alternating magnetic field can be prevented from occurring.

  That is, since the alternating magnetic field is shifted by the bias magnetic field, the alternating magnetic field applied to the magnetic wire 38 deviates from the magnetization reversal point HP or -HP of the magnetic wire, so that no magnetization reversal occurs in the magnetic wire 38 and magnetization is performed. A response signal due to inversion is not generated (hereinafter, this is referred to as demagnetization of the magnetic wire 38).

  Thereby, when an alternating magnetic field is applied, the magnetic wire 38 embedded in the packaging material 34 is not detected.

  Further, the magnetic band 40 is demagnetized by applying a predetermined magnetic field, for example, applying a strong magnetic field in the opposite direction to the magnetized magnetism. Thereby, by removing the bias magnetic field of the magnetic wire 38, the magnetic wire 38 generates a response signal to the alternating magnetic field (hereinafter, this is referred to as magnetization of the magnetic wire 38).

  Thus, by applying an alternating magnetic field to the packaging material 34 in which the magnetic wire 38 is embedded, the magnetic wire 38 generates a response signal in response to the alternating magnetic field, and the magnetic wire 38 embedded in the packaging material 34 is detected. Is possible.

  On the other hand, as the packaging material 34, paper, polyamide-based synthetic fibers, resin materials such as vinyl and polypropylene, and metal materials such as aluminum foil can be used. Further, it may be a wrapping of an article, and further may be a bottling, a can or the like.

  When paper is used as the packaging material 34, the magnetic wire 38 and the magnetic band 40 may be inserted into the packaging material 34. In addition, the packaging material 34 may be a stack of metal sheets such as paper, resin sheets, and aluminum foil. In this case, the magnetic wire 38 and the magnetic body 40 are sandwiched between the two sheets. It can be embedded by sticking two sheets.

  When a metal can such as an aluminum can is used as the package 32, a packaging material 34 (for example, aluminum) having a low melting point of the magnetic wire 38 and the magnetic strip 40 is used, and the magnetic wire 38 and the magnetic strip 40 are placed in a mold. What is necessary is just to pour and shape | mold aluminum in the state left.

  Furthermore, for PET bottles or the like, the magnetic wire 38 and the magnetic band 40 may be embedded in the PET bottle itself, but the magnetic wire 38 and the magnetic band 40 are embedded in a resinous sheet or film surrounding the PET bottle. It is more preferable to embed.

  Further, the thickness (outer diameter) of the magnetic wire 38 and the magnetic band 40 can be regarded substantially as the outer diameter of the magnetic wire 38 by using powder as the magnetic band 40, so that the surface of the packaging material 34 can be formed. Unevenness does not occur. Therefore, the barcode 36 or the like can be easily printed on the packaging material 34 by using a printing apparatus such as a printer.

  In the following description, articles such as packaged articles 32 in which the barcode 36 is formed on the magnetic wire 38 and the magnetic band 40 are collectively referred to as the commodity 32.

  On the other hand, as shown in FIG. 1, the gate antenna 14 is provided as a detecting means, and is generated by an excitation coil 42 that generates an alternating magnetic field by the power (AC power) supplied from the controller 18 and the excitation coil 42. A detection coil 44 that detects a pulse-like response signal generated by the magnetic wire 38 with respect to the alternating magnetic field generated is included. That is, a current corresponding to an alternating magnetic field is induced in the detection coil 44 and a current corresponding to a pulse-like response signal generated by the magnetic wire 38 is induced.

  The controller 18 determines the presence / absence of a response signal generated by the magnetic wire 38 by removing a low-frequency component corresponding to the period of the alternating magnetic field from the current induced in the detection coil 44.

  The controller 18 operates the gate antenna 14 at a predetermined timing. At this time, the controller 18 supplies power with the exciting coil 42 and confirms whether or not the detection coil 44 has detected a response signal. The operating timing of the gate antenna 14 may always be in an operating state when the security gate 30 is open, and is operated by detecting the passing timing of a customer or the like using an optical sensor or the like. There may be.

  When the detection coil 44 detects a response signal while the gate antenna 14 is operating, the controller 18 lights or blinks the warning 16 or the like, and the product 32 passes through the security gate 30 in an unintended state. This is reported.

  On the other hand, the operation unit 12 includes a demagnetizing coil 46, a magnetizing coil 48, an antenna unit 50, and a selection switch 52.

  The antenna unit 50 is provided with an excitation coil 54 that generates an alternating magnetic field by the electric power supplied from the controller 18 and a detection coil 56 that induces a current corresponding to a response signal generated by the magnetic wire 38 by the alternating magnetic field. 18 can detect whether or not the magnetic wire 38 is magnetized by using the antenna unit 50 provided in the operation unit 12. The detection result may be displayed by providing display means such as an LCD on the operation unit 12.

  The degaussing coil 46 and the magnetizing coil 48 emit an electric field having a predetermined strength. The magnetic field generated by the degaussing coil 46 and the magnetic field generated by the magnetizing coil 48 are in opposite directions.

  As a result, the operation unit 12 magnetizes the magnetic band 40 by operating the demagnetizing coil 146 when the magnetic band 40, that is, the bar code 36 of the product 32 is facing, so that a bias magnetic field is applied to the magnetic wire 38. The magnetic wire 38 is demagnetized as given.

  Further, the operation unit 12 demagnetizes the magnetic band 40 by operating the magnetizing coil 48 in a state where the magnetized magnetic bands 40 face each other, and the magnetic wire 38 responds by an alternating magnetic field. It is possible to return to a magnetized state where a signal can be emitted.

  The operations of the demagnetizing coil 46, the magnetizing coil 48, and the antenna unit 50 are switched by the operation of the selection switch 52. Normally, the demagnetizing coil 46 is operable.

  On the other hand, the operation unit 12 is provided integrally with the barcode reader 28 of the POS system 24. FIG. 5 shows a schematic configuration of a main part of the barcode reader 28.

  The bar code reader 28 is provided with a measuring unit 58 in which a light projecting unit that emits light of a predetermined wavelength and a light receiving unit that receives reflected light of light emitted from the light projecting unit are integrated. By facing the part 58 to the barcode 36 (not shown in FIG. 5), the barcode 36 can be read.

  In the barcode reader 28, a coil unit 60 is disposed around the measurement unit 58. By making the measurement unit 58 face the barcode 36, the coil unit 60 can also face the barcode 38. ing.

  Although not shown, the coil unit 60 is provided with an antenna unit 50 (an excitation coil 54 and a detection coil 56) together with the demagnetizing coil 46 and the magnetizing coil 48 described above. In addition, although arrangement | positioning of each coil may be arbitrary and FIG. 5 has illustrated the handy type barcode reader 28, also in the barcode reader 28A provided in the register counter 22, the coil unit 60 is It is provided so as to face the barcode 36 when the barcode 36 is read.

  In the carry-out inspection system 10, as described above, the degaussing coil 46 is normally operable by the selection switch 52, and the degaussing coil 46 is operated in conjunction with the reading of the bar code 36 by the bar code reader 28. It is supposed to be.

  Thereby, in the carry-out inspection system 10, when the barcode 36 of the product 32 is read, the magnetic wire 38 on which the barcode 36 is superimposed is demagnetized.

  In the carry-out inspection system 10, the operation of the magnetizing coil 48 is selected by operating the selection switch 52 in a state where the measuring unit 58 of the barcode reader 28 is opposed to the barcode 36. Magnetization can be performed, and whether or not the magnetic wire 38 is magnetized can be confirmed by selecting the operation of the antenna unit 50.

  In the store (store 20) where the carry-out inspection system 10 configured in this way is provided, packaging is performed by the embedded magnetic wire 38 and the packaging material 34 in which the bar code 36 is formed on the magnetic strip 40. The products 32 such as the packaged goods displayed are displayed in the store 22, and the customer using the store moves to the checkout counter 22 with the desired product 32 and performs settlement.

  In the cashier counter 22, the store clerk reads the barcode 36 formed on the product 32 by the barcode reader 28, thereby inputting the purchased product to the POS system 24 and summing up the purchase price. By liquidating, the product is delivered to the customer.

  By the way, in the product 32 in the store 22, the magnetic wire 38 and the magnetic band 40 are embedded in the packaging material 34 or the exterior, and the barcode 36 is formed so as to overlap the magnetic wire 38 and the magnetic band 40. The bar code reader 28 is provided with the operation unit 12 of the carry-out inspection system 10.

  In the operation unit 12, when the barcode 36 is read by the barcode reader 28, the demagnetizing coil 46 is activated. Thereby, the packaging material 34 of the product 32 and the magnetic wire 38 embedded in the exterior are demagnetized.

  At this time, since the barcode reader 28 is operated with respect to the product 32 at a predetermined interval, the degaussing coil 48 and the like can be arranged at an appropriate interval with respect to the magnetic wire 38, and an accurate operation can be performed. It is possible.

  On the other hand, in the store, a security gate 30 is provided at a customer exit, and the gate antenna 14 is provided in the security gate 30. In the carry-out inspection system 10, an alternating magnetic field is generated from the exciting coil 42 of the gate antenna 14, and a response signal generated by the magnetic wire 38 provided on the product 32 is detected with respect to the alternating magnetic field.

  Here, in the product 32 in which the barcode 36 is read by the barcode reader 28, the magnetic wire 38 is demagnetized by the operation of the demagnetizing coil 46. For this reason, the magnetic wire 38 is not detected by the gate antenna 14 when the finished product 32 passes through the security gate 30.

  On the other hand, the magnetic wire 38 is not demagnetized in the product 32 that does not pass through the register counter 22 and has not been cleared. For this reason, when the product 32 passes through the security gate 30, the magnetic wire 38 in the product 32 generates a response signal to the alternating magnetic field generated by the excitation coil 42 of the gate antenna 14, and this response signal is detected. It is detected by the coil 44.

  Thereby, it is notified that the unsettled product 32 is about to be taken out by the lighting of the warning lamp 16 or the like. Therefore, it is possible to reliably prevent the unchecked product 32 from being taken out of the store 22.

  Further, by removing the magnetic wire 38 from the product 32, the product 32 can pass through without being detected by the gate antenna 14 of the security gate 30, but in this product 32, the magnetic wire 38 is placed in the packaging material 34. In order to remove the magnetic wire 38, the product 32 must be opened or the packaging material 34 must be broken.

  This makes it substantially difficult to remove the magnetic wire 38 from the product 32. Therefore, by using the product 32 in which the magnetic wire 38 is embedded in the packaging material 34 or the exterior and the carry-out inspection system 10, it is possible to reliably prevent the unchecked product 32 from being illegally taken out of the store 22. it can.

  On the other hand, after the barcode 38 is read by the barcode reader 28, the product 32 that has not been liquidated or the product 32 that has been liquidated may be returned from the customer. At this time, since the magnetic wire 38 is demagnetized, the corresponding product 32 can be taken out without being detected by the gate antenna 14 if it is returned to the store 22 as it is.

  From here, the barcode reader 28 is provided with a magnetizing coil 48, and the selector switch 52 is operated in a state where the barcode reader 28 faces the barcode 38 of the product 32 to be returned, The magnetizing coil 48 is activated.

  The demagnetization of the magnetic wire 38 is performed by magnetizing the magnetic band 40 to form a bias magnetic field, and the magnetizing coil 48 demagnetizes the magnetic band 40. As a result, the bias magnetic field disappears, and the magnetic wire 38 enters a magnetized state in which a response signal to the alternating magnetic field is generated.

  In this way, by magnetizing the magnetic wire 38, even the returned product 32 is detected by the gate antenna 14 when it is illegally taken out.

  In this way, in the carry-out inspection system 10, the magnetizing coil 48 is provided in the bar code reader 28 so that the magnetic wire 38 can be simply made effective. Therefore, even if the product 32 demagnetized from the magnetic wire 38 is returned, You can easily accept returns.

  In the carry-out inspection system 10, the barcode reader 28 is provided with the antenna unit 50, and the antenna unit 50 can be operated by operating the selection switch 52.

  Thereby, since it is possible to confirm whether the magnetic wire 38 is in a magnetized state or a demagnetized state by the barcode reader 28, it is possible to prevent the product 32 magnetized from the magnetic wire 38 from being delivered to the customer. Thus, it is possible to reliably prevent the demagnetized product 32 from being returned to the store 22.

  As described above, in the carry-out inspection system 10, it is possible to perform an accurate process on the returned merchandise 32 with a simple operation while reliably preventing the merchandise 32 in the store 22 from being illegally taken out.

  In addition, although the carrying-out inspection system 10 was provided in the store and demonstrated here, the utilization method of the carrying-out inspection system of this invention is not restricted to this. For example, it can be used to prevent unauthorized take-out of packaged goods stored in a warehouse.

  Further, the present invention can be applied not only to warehouses but also to carrying out inspections for books in libraries.

  At this time, for example, as shown in FIG. 6, the magnetic material 38 and the magnetic band 40 are embedded in the exterior paper such as the back cover, the front cover, and the back cover of the book 62 so as to overlap the magnetic material. A book code 64 or the like is formed. That is, the magnetic wire 38 and the magnetic band 40 are embedded in a predetermined position of the exterior paper of the book 62, and the book code 64 is formed so as to overlap the magnetic wire 38 and the magnetic band 40, so that the book 62 can be borrowed or returned. Sometimes, the book code 64 is read by a code reader such as a barcode reader.

  In the code reader at this time, similarly to the above-described barcode reader 28, the operation unit 12 is provided integrally, and at the time of lending, the magnetic wire 38 is demagnetized in accordance with the code reading, and at the time of return, When the book code 64 of the book 62 returned by the code reader is read, the magnetic wire 38 is magnetized.

  As a result, when the book 62 that has not been approved for lending passes through the carry-out port provided with the gate antenna 14, this book 62 can be accurately detected. Further, since the magnetic wire 38 is embedded in the exterior of the book 62, the magnetic wire 38 is not removed from the book 62.

  Therefore, it is possible to reliably prevent the book 62 from being taken out illegally.

  In the present embodiment described above, the configuration of the present invention is not limited. For example, in this embodiment, the operation unit 12 is provided in the barcode reader 28 of the POS system 24, but only the operation unit 12 may be provided as a dedicated portable operation terminal for the carry-out management system 10. .

  In the present embodiment, the antenna unit 50 including the excitation coil 54 and the detection coil 56 is provided in the operation unit 12 to detect whether the magnetic wire 38 of the product 32 is magnetized or demagnetized. However, the operation 12 only needs to be provided with at least the demagnetizing coil 46 and the magnetizing coil 48. Thus, even if a return request for the corresponding product is made after demagnetizing the magnetic wire 38, It is possible to respond quickly to requests.

  Furthermore, the carry-out inspection system of the present invention is not limited to the carry-out inspection system 10, and any configuration can be applied.
