  Embodiments of the present invention will be described below with reference to the drawings. In the drawings attached to the present specification, for the sake of illustration and ease of understanding, the scale, the vertical / horizontal dimension ratio, and the like are appropriately changed and exaggerated from those of the actual product.

(Container)
First, a description will be given of a container 30 in which articles are stored, which is a target for performing a verification method using the verification system 10 according to the present embodiment. FIG. 3 is a cross-sectional view showing the storage body 30.

As shown in FIG. 3, the storage body 30 is configured in a box shape, and inside the storage body 30, a storage section 40 in which an article 41 is stored, and an attached document disposed on the storage section 40. 35 are accommodated. In the claims attached to the present application, an article stored in the storage body 30 is also referred to as a stored article. In the present embodiment, the case where the article 41 accommodated in the accommodating portion 40 is a medicine 41 manufactured by a pharmaceutical manufacturer will be described. In the following description, the medicine stored in the storage body 30 is also referred to as a stored medicine 41.
In addition, the articles accommodated in the accommodation unit 40 are not limited to medicines, and various items that require a corresponding supplementary document such as health food can be accommodated in the accommodation unit 40.

  The container 30 is configured such that the stored medicine 41 and the attached document 35 are not visually recognized from the outside. For example, the storage body 30 includes an opaque layer 31 made of paper or opaque resin. Here, “opaque” means that the transmittance of visible light in the opaque layer 31 is so small that objects such as the stored medicine 41 and the attached document 35 on the other side of the opaque layer 31 cannot be visually recognized. Means. As the paper for constituting the opaque layer 31, paper generally used for forming a box for storing a commercially available medicine can be used, and for example, paperboard board can be used. Among them, white paperboard such as high-grade whiteboard paper, special whiteboard paper, Manila ball, and white ball is often used. As the opaque resin for constituting the opaque layer 31, for example, styrene foam, polyethylene, polypropylene, polyethylene terephthalate, or the like can be used.

  In FIG. 3, there are gaps between the opaque layer 31 of the container 30 and the container 40 and between the container 40 and the attached document 35 in order to make the drawing easy to see. Such a gap may not exist.

  As long as an electromagnetic wave having a frequency range of 0.1 THz to 3 THz can pass through the opaque layer 31, the thickness of the opaque layer 31 is not particularly limited. For example, the thickness of the paper or opaque resin constituting the opaque layer 31 is appropriately set in consideration of the light shielding properties and strength required for the storage body 30. In the present embodiment, an example in which the opaque layer 31 is formed thick enough to reflect or absorb infrared rays will be described. Note that “reflect or absorb infrared rays” means that when the storage body 30 is irradiated with infrared rays, the infrared rays do not pass through the storage body 30 at all, and even though infrared rays pass through the storage body 30 It means that the amount is so small that it cannot be detected by the sensor.

(Container)
Next, the accommodating part 40 is demonstrated. In this Embodiment, the accommodating part 40 is for hold | maintaining the stored pharmaceutical 41 formed as a tablet. As shown in FIG. 3, the accommodating portion 40 is formed with an accommodating space 43 for accommodating the medicinal product 41 and has a translucent member 42 having translucency and a translucency so as to seal the accommodating space 43. And a metal foil 44 attached to the member 42. Here, “translucent” means that the transmittance of visible light in the translucent member 42 is so large that the stored medicine 41 accommodated in the accommodating space 43 can be visually recognized through the translucent member 42. It means that The metal foil 44 is configured such that when the stored medicine 41 is strongly pressed from the translucent member 42 side, the metal foil 44 is broken and the stored medicine 41 jumps out of the storage space 43. Thus, the accommodating part 40 is comprised as what is called a PTP (press through package) package.

  As long as electromagnetic waves such as terahertz waves and infrared rays can be transmitted, the material constituting the translucent member 42 is not particularly limited. As a material of the translucent member 42, for example, a polypropylene resin or a polyvinyl chloride resin can be used. As a metal material constituting the metal foil 44, a metal material having a barrier property against a gas such as water vapor can be used. For example, aluminum can be used. Since the metal foil 44 contains a metal material, electromagnetic waves such as terahertz waves and infrared rays that reach the metal foil 44 through the translucent member 42 and the stored medicine 41 are transmitted by the metal foil 44 as described later. Reflected.

(Attached document)
Next, the attached document 35 bundled with the stored medicine 41 will be described with reference to FIGS. FIG. 4 is an enlarged plan view showing the attachment document 35 shown in FIG.

  As shown in FIG. 3 and FIG. 4, necessary items 36 are described in the attached document 35, and an identification image 37 is provided in the attached document 35. The necessary items 36 are printed on the medium 39, and the identification image 37 is provided on the medium 39. As the medium 39, general-purpose paper such as plain paper can be used. The thickness of the medium 39 made of paper is, for example, about 100 μm. In this case, the terahertz wave can be transmitted through the medium 39 while maintaining high intensity, but the infrared ray is absorbed to some extent by the medium 39 and attenuates.

  The necessary items 36 described in the attachment document 35 include items defined by the Pharmaceutical Affairs Law, for example, items related to pharmaceutical usage, dosage and other necessary precautions in handling and handling. Such a necessary item 36 is appropriately created according to the type of the medicine. That is, the necessary item 36 is intended for a specific drug and cannot be used for all drugs. In the following description, the medicine targeted by the necessary item 36 described in the attached document 35 housed in the container 30 is also referred to as a target medicine. In order to ship a medicine, it is necessary that the target medicine corresponding to the attached document 35 and the housed medicine 41 bundled with the attached document 35 coincide with each other.

  The identification image 37 provided in the attachment document 35 is for representing the target medicine corresponding to the attachment document 35. For example, when the target drug is a drug called A, the identification image 37 includes information for indicating that the target drug is drug A. The specific form of the identification image 37 is not particularly limited. For example, as the form of the identification image 37, a one-dimensional barcode or a two-dimensional barcode can be adopted. The identification image 37 may be an image showing OCR numbers, numbers, characters, designs, symbols, and the like. In the present embodiment, an example in which the identification image 37 is a one-dimensional barcode will be described.

  The identification image 37 includes a conductor 38 that can reflect infrared rays, terahertz waves, and the like. For example, as shown in FIG. 4, the identification image 37 includes a plurality of linear conductors 38 extending in one direction and arranged in a direction orthogonal to the one direction. In FIG. 4, the width of the conductor 38 is represented by a symbol w, and the interval between two adjacent conductors 38 is represented by a symbol s. The width w and the interval s are appropriately set so that what the target drug is can be read from the width w and the interval s. As the conductor 38, granular carbon black or granular metal can be used.

(Verification system)
Next, referring to FIG. 1 and FIG. 2, the stored medicine 41 stored in the storage body 30 corresponds to the requirement 36 described in the attached document 35 stored in the storage body 30. A collation system 10 for collating will be described.

  The collation system 10 can sequentially perform the collation method according to the present embodiment on a plurality of storage bodies 30 that are placed on a conveying device 18 such as a belt conveyor and are conveyed in the direction of arrow T. It is configured to be able to. As shown in FIG. 1, such a collation system 10 includes an irradiation device 12 that irradiates the storage body 30 with the electromagnetic wave L <b> 1 and an information acquisition device 14 that includes a detector 15 that detects the electromagnetic wave L <b> 2 reflected from the storage body 30. And a computer 20. Although FIG. 1 shows an example in which the electromagnetic wave L1 is incident on the storage body 30 from a direction inclined with respect to the normal direction of the upper surface of the storage body 30, the present invention is not limited to this. As long as the electromagnetic wave L2 obtained by reflection from the storage body 30 can be appropriately detected, the incident angle of the electromagnetic wave L1 and the positions of the irradiation device 12 and the detector 15 are not particularly limited. Each storage body 30 is preferably configured so that the arrangement direction of the plurality of linear conductors 38 constituting the identification image 37 of the attachment document 35 stored in the storage body 30 matches the transport direction of the transport device 18. It is placed on the transport device 18.

[Irradiation device]
In the present embodiment, the irradiation device 12 is configured to generate a terahertz wave having a frequency range of 0.1 THz to 3 THz as an electromagnetic wave and radiate it toward the storage body 30. The electromagnetic wave has a beam diameter that irradiates a part of the housing 30. The irradiation device 12 may include an optical system in order to adjust the traveling direction of the electromagnetic wave and the beam diameter.

  The frequency range of the electromagnetic wave generated in the irradiation device 12 may be 1 THz to 2 THz. This makes it easier for electromagnetic waves to pass through the housing 30.

  As a generation system of electromagnetic waves composed of terahertz waves, a generation system using a photoconductive antenna or a semiconductor can be used. In addition, as a generation system, a generation system that generates an electromagnetic wave using a nonlinear optical effect such as optical parametric or difference frequency mixing generated by irradiating a nonlinear optical crystal with laser light can be used. In addition, examples of the generation system include a quantum cascade laser (QCL), a resonant tunnel diode (RTD), a gyrotron, and a free electron laser (FEL).

Among these, a generation system that generates electromagnetic waves composed of terahertz waves using nonlinear optical effects such as optical parametric and difference frequency mixing can generate terahertz waves having high intensity. For example, a terahertz wave having an intensity of 300 mW or more or an intensity of 1 W or more can be generated. For this reason, even when the opaque layer 31 of the container 30 and the medium 39 of the attachment document 35 have a large thickness, the electromagnetic wave L2 returned from the container 30 can be detected with sufficient accuracy. it can. For example, when a generation system that generates electromagnetic waves using nonlinear optical effects such as optical parametric and difference frequency mixing is used, the paper constituting the opaque layer 31 should have a thickness in the range of 100 μm to 1 cm. Can do. As a result, the collation system 10 and the collation method implemented by the collation system 10 can be used over a wider field.
The nonlinear optical crystal is a crystal that responds nonlinearly, that is, not proportional to the electromagnetic field of light when intense light such as laser light is incident. The nonlinear optical effect is a nonlinear response, that is, a response that is not proportional to the electromagnetic field of light. The optical parametric and difference frequency mixing described above are a kind of nonlinear optical effect.

[Information acquisition device]
Next, the information acquisition device 14 will be described. The information acquisition device 14 is for acquiring identification image information based on the electromagnetic wave L <b> 2 reflected by the conductor 38 of the identification image 37 and stored medicine information based on the electromagnetic wave transmitted through the stored medicine 41. As described above, the information acquisition device 14 includes the detector 15 that detects the intensity of the electromagnetic wave L <b> 2 reflected from the storage body 30. In addition, as shown in FIG. 2, the information acquisition device 14 further includes an information processing unit 16 that derives the identification image information and the stored medicine information described above based on the intensity of the electromagnetic wave L2 detected by the detector 15. Also good. Details of the identification image information and the stored medicine information will be described later.

〔calculator〕
As shown in FIG. 2, the computer 20 includes an indexing device 21 and a verification device 22. Of these, the indexing device 21 is for determining the type of the target medicine targeted by the necessary item 36 described in the attached document 35 based on the identification image information described above. The collation device 22 is for collating whether or not the stored medicine 41 matches the target medicine targeted by the necessary item 36 based on the above-mentioned stored medicine information. The collation device 22 includes a determination reference generation unit 23 and a determination unit 24. Detailed functions of the determination criterion generation unit 23 and the determination unit 24 will be described later.

  Next, the operation and effect of the present embodiment having such a configuration will be described. Here, the stored medicine 41 stored in the container 30, which is implemented by using the above-described verification system 10, corresponds to the necessary item 36 described in the attached document 35 stored in the container 30. A collation method for collating whether or not it is an object will be described with reference to FIGS.

(Package preparation process)
First, the storage body 30 in which the attachment document 35 and the storage unit 40 in which the stored medicine 41 is stored is prepared. In addition, the positional relationship between the storage unit 40 and the attached document 35 in the storage body 30 may be determined in advance. In this case, the electromagnetic wave L2 detected by the detector 15 is transmitted through which of the plurality of elements stored in the storage body 30 is the irradiation position of the electromagnetic wave L1 on the storage body 30. Accordingly, it becomes predictable to some extent.

(Irradiation process)
Next, an irradiation step of irradiating the storage body 30 with the electromagnetic wave L1 using the irradiation device 12 is performed. As the electromagnetic wave L1, an electromagnetic wave having a first frequency is used. Here, the electromagnetic wave having the first frequency is an electromagnetic wave belonging to a frequency range sufficiently narrower than the frequency range of the electromagnetic wave classified as a terahertz wave. For example, when the spectrum of the first electromagnetic wave is observed, the half width of the spectrum of the first electromagnetic wave is in the range of 0.05 THz to 0.2 THz.

  The electromagnetic wave L <b> 1 is irradiated from the light transmissive member 42 side of the housing portion 40. At this time, the electromagnetic wave L <b> 2 reflected by the conductor 38 of the identification image 37 or the metal foil 44 of the housing portion 40 is detected by the detector 15.

FIGS. 5A to 5D respectively show typical paths among paths where the electromagnetic wave L1 irradiated to the storage body 30 is reflected and returned as the electromagnetic wave L2. 5A to 5D, the electromagnetic waves L2 that are reflected and reach the detector 15 are indicated by reference numerals L21, L22, L23, and L24, respectively.
FIG. 5A shows a path through which the electromagnetic wave L1 transmitted through the opaque layer 31 of the housing 30 is reflected by the conductor 38 of the identification image 37 and reaches the detector 15.
FIG. 5B shows a path through which the electromagnetic wave L1 transmitted through the opaque layer 31 of the container 30, the gap between the conductors 38 of the identification image 37 and the medium 39 is reflected by the metal foil 44 of the container 40 and reaches the detector 15. Is shown.
FIG. 5C shows an electromagnetic wave L1 transmitted through the opaque layer 31 of the container 30, the medium 39 of the identification image 37, the translucent member 42 of the container 40 and the stored medicine 41 by the metal foil 44 of the container 40. A path that is reflected and reaches the detector 15 is shown.
FIG. 5D shows that the electromagnetic wave L1 transmitted through the opaque layer 31 of the container 30, the medium 39 of the identification image 37, and the translucent member 42 of the container 40 is reflected by the metal foil 44 of the container 40 and detected. The path to the vessel 15 is shown.

  In the graph shown in FIG. 6, the intensity of the electromagnetic wave L2 detected by the detector 15 while the container 30 is irradiated with the electromagnetic wave L1 while moving the container 30 at a predetermined speed using the transport device 18. The horizontal axis is plotted as time. The unit of intensity on the vertical axis is an arbitrary unit. In FIG. 6, the intensity | strength of the electromagnetic waves L21-L24 shown to Fig.5 (a)-(d) is each represented with code | symbol P21-P24.

(Information acquisition process)
Hereinafter, based on the measurement results of the intensity of the electromagnetic waves L21 to L24, the identification image information based on the electromagnetic wave reflected by the conductor 38 of the identification image 37 and the stored medicine information based on the electromagnetic wave transmitted through the stored medicine 41 are acquired. The information acquisition process will be described.

  As is clear from FIG. 5C, the electromagnetic wave L23 reaches the detector 15 after passing through more components than other electromagnetic waves. For this reason, as shown in FIG. 6, the intensity P23 of the electromagnetic wave L23 is smaller than the intensity of other electromagnetic waves. When the stored medicine 41 is formed as a tablet as in the present embodiment, the intensity P23 of the electromagnetic wave L23 that has passed through the stored medicine 41 changes according to the shape of the stored medicine 41, as shown in FIG. Sometimes. Here, the minimum intensity corresponding to the electromagnetic wave L23 is defined as intensity P23.

  As is apparent from FIG. 5A, the electromagnetic wave L21 has fewer components to transmit than the other electromagnetic waves. For this reason, as shown in FIG. 6, the intensity P21 of the electromagnetic wave L21 is larger than the intensity of other electromagnetic waves.

  In the electromagnetic wave L22 and the electromagnetic wave L24, compared with the electromagnetic wave L21, attenuation amount becomes large by the amount which permeate | transmits the medium 39 of the attachment document 35. FIG. On the other hand, the amount of attenuation of the electromagnetic wave L22 and the electromagnetic wave L24 is smaller than the electromagnetic wave L21 by the amount that does not pass through the stored medicine 41. Therefore, as shown in FIG. 6, the intensity P22 and the intensity P24 of the electromagnetic wave L22 and the electromagnetic wave L24 are located between the intensity P21 of the electromagnetic wave L21 and the intensity P23 of the electromagnetic wave L23.

  As described above, the strength P21 and the strength P22 are repeatedly measured according to the presence or absence of the conductor 38 in the identification image 37. Accordingly, the strength P21 and the strength P22 include information on the shape of the identification image 37. From this, it can be said that the information on the intensity P21 and the intensity P22 is information on the identification image 37, that is, identification image information I1, as shown in FIG.

  Further, as described above, the strength P23 and the strength P24 are measured according to the presence or absence of the stored medicine 41. Further, the difference between the strength P23 and the strength P24 includes information on the degree to which the stored medicine 41 absorbs the electromagnetic wave L1, that is, information on the absorption rate of the electromagnetic wave L1 in the stored medicine 41. From this, it can be said that the information on the strength P23 and the strength P24 is information on the stored medicine 41, that is, stored medicine information I2, as shown in FIG.

(Indexing process)
Next, based on the identification image information I1 obtained in the information acquisition process described above, an indexing process is performed for determining the type of the target medicine targeted by the necessary item 36 described in the attached document 35. As described above, the identification image information I1 is obtained by irradiating the storage body 30 moving at a predetermined speed with the electromagnetic wave L1. In this case, the identification image information I1 indicates the position of the attached document 35 on the medium 39 in consideration of the moving speed of the container 30 on the transport device 18 and the arrangement of the irradiation device 12 and the detector 15. It can be converted into information on the shape of the identification image 37 by converting into coordinates. Therefore, based on the identification image information I1, information regarding the width w and the interval s of the conductor 38 of the identification image 37 can be acquired. As described above, the identification image 37 is formed as a one-dimensional barcode. For this reason, based on the information regarding the width w and the interval s of the conductor 38 of the identification image 37, the type of the target medicine targeted by the necessary item 36 described in the attached document 35 can be determined. Here, it is determined that the target medicine is medicine A.

(Verification process)
Next, based on the stored medicine information I2, a matching step is performed to check whether the stored medicine 41 matches the target medicine for which the necessary items 36 are targeted.

[Criteria generation process]
First, based on the type of the target drug targeted by the necessary items 36 determined by the above-described indexing process, data on the absorption rate of electromagnetic waves in the target drug is acquired. FIG. 7 is a diagram illustrating an example of an absorption spectrum of the pharmaceutical A. In FIG. 7, the horizontal axis is frequency, and the vertical axis is electromagnetic wave absorption rate at which a pharmaceutical absorbs electromagnetic waves. Here, the absorption rate on the vertical axis is an arbitrary unit. Here, the value of the absorption rate DA is acquired as the electromagnetic wave absorption rate of the pharmaceutical A at the first frequency.

  Next, the drug A targeted by the necessary item 36 is stored in the storage space 43 of the storage unit 40, and the drug A stored in the storage space 43 is irradiated with the electromagnetic wave L1 having the first frequency. Assuming that the range R of the electromagnetic wave of the first frequency that can be detected in that case is calculated. Hereinafter, an example of a method for calculating the range R will be described.

  As is apparent from FIGS. 5C and 5D, the intensity P23 of the electromagnetic wave L23 is smaller than the intensity P24 of the electromagnetic wave L24 by the amount that passes through the stored medicine 41. For this reason, when the stored medicine 41 is the medicine A, the expected intensity P23 can be calculated by multiplying the intensity P24 by the absorption rate DA of the stored medicine 41 at the first frequency. Therefore, based on the absorption rate DA and the intensity P24 of the electromagnetic wave L24, the range R of the electromagnetic wave intensity that can be measured when the medicine A is stored in the storage space 43 can be calculated. Note that the range R is set to have a certain width in order to suppress erroneous determination due to the measurement error.

[Judgment process]
Then, the determination process which determines whether the intensity | strength P23 of the electromagnetic wave L23 of the 1st frequency which permeate | transmitted the accommodation pharmaceutical 41 enters into the range R calculated supposing the pharmaceutical A is implemented. When the strength P23 falls within the range R, the stored medicine 41 bundled with the attachment document 35 matches the target medicine, that is, the medicine A targeted by the necessary item 36 described in the attachment document 35. It is determined that On the other hand, when the strength P23 does not fall within the range R, it is determined that the stored medicine 41 bundled with the attachment document 35 does not match the medicine A. As described above, according to the present embodiment, it can be easily confirmed from the outside of the storage body 30 whether the appropriate attachment document 35 is stored in the storage body 30.

  By the way, it is known that the absorption spectrum of electromagnetic waves in pharmaceuticals varies greatly depending on the type of pharmaceutical. FIG. 7 shows, as an example, an absorption spectrum of the medicine B in addition to the absorption spectrum of the medicine A. As shown in FIG. 7, the absorption rate DA at which the drug A absorbs the electromagnetic waves of the first frequency is significantly larger than the absorption rate DB at which the drug B absorbs the electromagnetic waves of the first frequency. Therefore, there is a large difference between the intensity of the electromagnetic wave detected after passing through the medicine A and the intensity of the electromagnetic wave detected after passing through the medicine B.

  Here, consider a case where the drugs that can be manufactured on the same line of the drug manufacturer are limited to the drugs A and B shown in FIG. In this case, the role of the above-described range R is to discriminate between the medicine A and the medicine B. Here, as described above, there is a large difference between the intensity of the electromagnetic wave transmitted through the medicine A and the intensity of the electromagnetic wave transmitted through the medicine B. Therefore, as shown in FIG. 6, even when the range R has a certain width, it is possible to accurately determine whether the medicine corresponding to the strength P23 is the medicine A or the medicine B. it can. Therefore, even if the measurement results of the strengths P23 and P24 include a measurement error based on the measurement device and a measurement error based on the shape and orientation of the stored medicine 41, the medicine A is erroneously identified as the medicine B. And the probability of making the reverse determination can be reduced. Thereby, the collation method using the collation system 10 can be implemented with a high yield.

  Note that various modifications can be made to the above-described embodiment. Hereinafter, modified examples will be described with reference to the drawings. In the following description and the drawings used in the following description, the same reference numerals as those used for the corresponding parts in the above embodiment are used for the parts that can be configured in the same manner as in the above embodiment. A duplicate description is omitted. In addition, when it is clear that the operational effects obtained in the above-described embodiment can be obtained in the modified example, the description thereof may be omitted.

(Example using transmitted electromagnetic waves)
In the above-described embodiment, the example in which the electromagnetic wave L <b> 2 reflected by the component housed in the housing body 30 is detected has been shown. However, the present invention is not limited to this, and as shown in FIG. 8, the electromagnetic wave L <b> 3 that has passed through the components housed in the housing 30 may be detected by the detector 15. In the present modification, the accommodating portion 40 for accommodating the stored medicine 41 is made of a material having translucency.

  In the present modification, a part of the electromagnetic wave L <b> 1 irradiated to the identification image 37 passes through the gap of the conductor 38 and reaches the detector 15. The other electromagnetic waves L1 cannot reach the detector 15 because they are reflected by the conductor 38. In this case, the detector 15 detects electromagnetic waves at a period corresponding to the arrangement of the conductors 38 of the identification image 37. Therefore, even when the electromagnetic wave L3 transmitted through the storage body 30 is detected, the identification image information I1 including information regarding the shape of the identification image 37 can be obtained.

  In the present modification, a part of the stored medicine 41 and the electromagnetic wave L1 irradiated to the periphery thereof passes through the stored medicine 41 and reaches the detector 15. Other electromagnetic waves L1 reach the detector 15 without passing through the stored medicine 41. In this case, the detector 15 detects the electromagnetic wave reflecting the intensity according to the absorption rate of the electromagnetic wave L1 in the stored medicine 41. That is, even when the electromagnetic wave L3 transmitted through the storage body 30 is detected, the stored medicine information I2 including information on the presence / absence of the stored medicine 41 and the electromagnetic wave absorption rate of the stored medicine 41 can be obtained.

  According to this modification, based on the identification image information I1 and the stored medicine information I2 obtained as described above, by performing the above-described indexing step and collating step as in the case of the present embodiment, Whether or not the stored medicine 41 stored in the storage body 30 corresponds to the necessary item 36 described in the attached document 35 stored in the storage body 30 can be verified.

(Modification of storage body)
In the above-described embodiment, an example in which the attachment document 35 is disposed on the storage unit 40 inside the storage body 30 has been described. That is, the example in which the attachment document 35 and the accommodating portion 40 are arranged so as to overlap along the incident direction of the electromagnetic wave L1 is shown. However, the present invention is not limited to this, and as shown in FIG. 9, the accommodating portion 40 and the attached document 35 may be arranged so as not to overlap each other along the incident direction of the electromagnetic wave L1.

(Modification of attached document)
In the above-described embodiment, an example is shown in which the medium 39 of the attachment document 35 is composed of one layer. However, the present invention is not limited to this, and as shown in FIG. 10, the attachment document 35 may include a medium 39 that has been multilayered by being folded. In this case, the intensity of the electromagnetic wave reflected by the conductor 38 of the identification image 37 and detected by the detector 15 and the light reflected by the metal foil 44 of the housing portion 40 after passing through the sensing medium 39 and detected by the detector 15. The difference between the intensity of the electromagnetic wave becomes more remarkable. For this reason, the identification image information I1 regarding the shape of the identification image 37 can be acquired more accurately.

(Other variations)
In the above-described embodiment, an example in which the storage body 30 is configured in a box shape is shown. However, as long as the inside of the storage body 30 cannot be visually recognized, the shape and structure of the storage body 30 are not particularly limited.

  In the above-described embodiment, an example in which terahertz waves are used as electromagnetic waves has been described. However, the present invention is not limited to this, and infrared rays may be used as electromagnetic waves as long as they can pass through the opaque layer 31 of the container 30 and the medium 39 of the attached document 35.

  In the above-described embodiment, the necessary items 36 are described in the attached document 35 stored in the storage body 30, and the identification image 37 is provided in the attached document 35. However, as long as the correspondence between the necessary item 36 and the identification image 37 is clear, the place where the necessary item 36 and the identification image 37 are provided is not particularly limited. For example, the necessary items 36 may be described on the inner surface of the storage body 30, and the identification image 37 may be provided on the inner surface of the storage body 30. Alternatively, the necessary items 36 may be described on the surface of the storage unit 40, and the identification image 37 may be provided on the surface of the storage unit 40.

  In the above-described embodiment, the stored medicine 41 is illustrated as a tablet. However, the form of the stored medicine 41 is not particularly limited as long as it shows a specific absorption spectrum. For example, the form of the stored medicine 41 may be powder or liquid.

  In the above-described embodiment, the example in which the electromagnetic wave having the first frequency is applied to the housing 30 has been described. However, the present invention is not limited to this, and the container 30 may be irradiated with electromagnetic waves over a wide frequency range. In this case, the detector 15 can detect the frequency spectrum of the electromagnetic wave reflected by the storage body 30 or the frequency spectrum of the electromagnetic wave transmitted through the storage body 30. Therefore, the detection result includes information on the absorption spectrum unique to the pharmaceutical product. For this reason, the kind of stored medicine stored in the storage unit 40 can be determined with higher accuracy. Therefore, the stored medicine and the target medicine can be more accurately collated.

  In the above-described embodiment, the information acquisition unit 14 is provided with the information processing unit 16 that derives the identification image information I1 and the stored medicine information I2 based on the intensity of the electromagnetic wave L2 detected by the detector 15. An example is shown. However, FIG. 2 is merely an example of the configuration of the verification system 10, and the specific configuration of each device is not particularly limited. For example, the information processing unit 16 may be a component of the computer 20. Moreover, the information acquisition apparatus 14 and the computer 20 may be comprised integrally.
