Description

  The present invention relates to an identification system and an opal composite for the identification system.

  In order to identify each of a plurality of articles that are similar in appearance, for example, there is a method of giving a characteristic to the appearance of the article by adding different patterns to the article. By such a method, a person who sees the article can identify the article based on the subjective feeling of the person, using an external feature based on a pattern or the like as a determination material. Further, for example, a wireless communication chip called an IC tag as described in Patent Document 1 described below is embedded in an article without depending on the appearance, and the appearance is similar based on identification information (ID) stored in the chip. Technology that identifies multiple items is also being used

JP 2002-183893 A

  However, in the case of the above-mentioned method of applying a pattern etc., there is a limit to the variations of patterns that humans can subjectively identify, so when the number of objects to be identified increases, It is difficult to make a judgment based on the subjectivity of the subject matter, and there is a problem that much time is required for identification. Although there is a method of clearly specifying an identification code consisting of a character string such as a number or an alphabetic character instead of a pattern, this method may impair the aesthetic appearance of the article. Further, in the method using the above-described IC tag technology, it is basically necessary to embed the IC tag in the article during the manufacturing process of the article, and the cost becomes relatively high. Although an IC tag can be attached to the surface of an article after the article is manufactured, this impairs the aesthetics of the article. The present invention also aims to solve these problems.

Based on the first identification information, whether the first identification information is obtained by irradiating the light transmitting member assembly portion composed of any combination of the plurality of types of the light with the light. Identifying the second light output from the second light receiving means Identification means for identifying, based on other information, whether the second identification information is obtained by irradiating the light transmissive body aggregate part with the light. The translucent body comprises an opal composite in which a plurality of aggregates composed of a plurality of silica particles are dispersed in a resin.

  Also provided is an opal composite for identification system, which is an opal composite for use in an identification system and can be attached to the identification object.

  According to the present invention, an object to be identified can be identified with high accuracy at a relatively low cost without impairing the aesthetic appearance of the identifier. According to the present invention, it is also possible to improve the aesthetic appearance of the identifier.

  The identification system 100 shown in FIG. 1 has a light transmitting member assembly 10 (transparent member collecting portions 10a to 10n) composed of a combination of a plurality of types of light transmitting members 13α to 13γ (see FIG. 3) each having different light transmission characteristics. And a light irradiating means 102 for irradiating light to the light transmitting body collecting portion, and a first identification light R1 composed of the transmitted light of the light transmitted through the light transmitting body collecting portion 10, and the received first identification light R1 The first light receiving means 104a for outputting the first identification information corresponding to the light and the second identification light R2 made up of the reflected light of the light transmitting body gathering part 10 are received, and the received second identification light R2 is received. Based on the second light receiving means 104b for outputting the second identification information and the first identification information output from the first light receiving means 104a, the first identification information is composed of any combination of a plurality of combinations. By irradiating light to the transparent body assembly In addition to discriminating whether the light is obtained, based on the second identification information output from the second light receiving means 104b, the second identification information is one of the plurality of transmission body aggregation portions. And identifying means 108 for identifying whether or not it is obtained by irradiating light. The identification system 100 also includes a storage unit 106 in which condition information used by the identification unit 108 is stored in advance.

The light irradiating means 102 has first irradiating means 102a that irradiates the entire light transmitting body assembly portion 10 with white light L1, and the first light receiving means 104a receives the first identification light R1 and receives the first identification light. Information representing the spatial distribution of the intensity of each of the light of a plurality of types included in R1 is output as first identification information. For example, the first identification information is represented as information representing the spatial distribution of the light C1 in the red wavelength band, information representing the spatial distribution of the light C2 in the yellow wavelength band, and the spatial distribution of the light C3 in the blue wavelength band. Information (see FIG. 4).

Each of the translucent bodies 13α to 13γ is made of an opal composite in which a plurality of aggregates 2 composed of a plurality of silica particles 1 are dispersed in a resin 4 and arranged. The plurality of types of translucent bodies 13α to 13γ have different light transmission characteristics by including different types of dyes in the resin 4, respectively. For example, the translucent body 13α is characterized in that the transmitted white light is reddish, the translucent body 13β is yellowed in transmitted white light, and the translucent body 13γ is characterized in that the transmitted white light is bluish. Have. Each of the light-transmitting member aggregate portions 10a to 10n is a combination of the same type of light-transmitting members 13α to 13γ. For example, information represented as the spatial distribution of light in the red wavelength band, information represented as the spatial distribution of light in the yellow wavelength band, and information represented as the spatial distribution of light in the blue wavelength band, which are obtained as the first identification information Have almost the same characteristics, and the transmitted light when the light transmitting body assembly 10n is irradiated with white light is reddish, yellowish, and bluish. It is a combination of light. The first irradiation unit 102a is, for example, an LED irradiation device that can emit white light. The first light receiving means 104a is a device that can measure the spatial distribution of light, such as a CCD element.

  The light irradiating means 102 also has second irradiating means 102b that scans and irradiates light L2 with respect to the light transmitting member assembly 10, and the second light receiving means 104b is a second identification that changes as the light is scanned. The time series information corresponding to the light R2 is output as the second identification information. As the light L2, for example, laser light having a specific peak wavelength can be used. The second irradiation means 102b is, for example, an LED irradiation device having an LED element or a laser light emitting device that emits laser light. The second light receiving means 104b is a light receiving device including a photodiode element, for example, and outputs an electrical signal corresponding to the intensity of the received light in time series as second identification information.

  The storage unit 106 and the identification unit 108 are provided in the information processing unit 120. The information processing unit 120 is also provided with a control unit 110 that is connected to each unit and controls the operation of each unit. The information processing unit 120 is a computer in which each means (storage means 106, identification means 108, control means 110, etc.) functions when a CPU (not shown) executes a program stored in the memory 106, for example. Note that the information processing unit 120 may be a dedicated device configured by combining, for example, an electronic circuit having a specific function, and the configuration of the light irradiation unit 102, the light receiving unit 104, and the information processing unit 120 is as follows. There is no particular limitation.

  In the identification system 100, each of the plurality of transparent body aggregates 10a to 10n is attached to each of the plurality of identification objects 11a to 11n (n is not particularly limited by an arbitrary number). The storage means 106 has a feature of spatial distribution of the intensity of each of the light of a plurality of wavelengths included in the first identification light R1 obtained when the entire light transmitting body aggregates 10a to 10n are irradiated with the white light L1. Is stored. In the present embodiment, as described above, the information representing the characteristics of the spatial distribution of the intensity of each of the light of a plurality of types of wavelengths is substantially the same for all of the light-transmitter assemblies 10a to 10n. The identification unit 108 refers to the condition information stored in the storage unit 106, and based on the first identification information output from the first light receiving unit 104a, the first identification information is any combination among a plurality of combinations. It is identified whether it was obtained by irradiating light to the transparent body assembly portion. More specifically, in the present embodiment, it is determined whether or not each of the light transmitting body aggregate portions 10a to 10n has a feature of spatial distribution of the intensity of each of a plurality of types of wavelengths. The storage means 106 also has a correspondence relationship between each of the plurality of light transmitting body aggregates 10a to 10n and each of the attached identification objects 11a to 11n (for example, the opal composite 10a is attached to the identification object 11a, Information such as the fact that the light aggregate unit 10b is attached to the identification object 11b is stored in advance. Further, the identification unit 108 refers to the condition information and the correspondence relationship stored in the storage unit 106, and the second identification information is attached to any of the plurality of identification target bodies 11 a to 11 n attached to the translucent body assembly unit. Whether it is obtained by irradiating with light L is identified.

All the translucent bodies 13α to 13γ used in the translucent aggregate sections 10a to 10n of the present embodiment are arranged in such a manner that aggregates 2 made of a plurality of silica particles 1 are dispersed in the resin 4. . In the aggregate 2, the silica particles 1 have a structure in which a plurality of layers arranged with a certain degree of regularity are stacked. When the surface composed of the silica particles 1 arranged in a layer form is the main surface 3, the direction and position of the main surface 3, the interval between the main surfaces 3 formed in a layer, and the like are different for each aggregate 2. Each of them is randomly arranged in the resin 4. When such opal composite 10 is irradiated with, for example, white light, the white light is reflected on each main surface 3 in the aggregate 2 and strengthens light of a specific wavelength, but the position and angle of the main surface 3 Depending on the difference, these intensifying wavelengths change.

  Since the aggregates 2 are dispersed in the light transmitting bodies 13α to 13γ in this way, the color of each aggregate 2 changes according to the viewing angle (that is, according to the viewing angle, the observer's The increasing wavelength of the light that reaches the eye changes). The effect of changing the wavelength (color) of light having a high intensity according to the viewing angle is called a play color effect and has an excellent aesthetic appearance. Moreover, since the arrangement positions of the aggregates 2 are randomly distributed, the intensity of light reflected by the aggregates 2 differs from place to place. It is virtually impossible to completely control the position (dispersion state) of the aggregates 2 in these translucent bodies 13α to 13γ, the orientation of the main surface 3 in each aggregate 2 and the spacing between layers. If there are a plurality of light bodies 13α to 13γ, it can be said that the states of the reflected light and the transmitted light are all different for each opal composite 10.

  On the other hand, each of the light transmitting body aggregates 10a to 10n is a combination of the same types of light transmitting bodies 13α to 13γ. For example, the spatial distribution of light in the red wavelength band obtained as the first identification information. , Information representing the spatial distribution of light in the yellow wavelength band, and information representing the spatial distribution of light in the blue wavelength band all have substantially the same characteristics. That is, the first identification information obtained from each of the light transmitting member aggregation portions 10a to 10n has a common feature that, for example, all are arranged in order of red, yellow, and blue from the left side.

  In addition, since the play effect itself is shared by the plurality of light transmitting body aggregate portions 10, the appearance characteristics of each of the plurality of light transmitting body aggregate portions 10 can be subjectively identified by humans. Not so big. In this way, the translucent member assembly 10 has a unified design feeling that the features on the appearance are not so large that humans can identify subjectively, while the reflected light is reflected with higher accuracy than humans can identify subjectively. When the states of transmitted light and light are compared, the states of reflected light and transmitted light are all different in each of the plurality of light transmitting body aggregate portions 10.

In the identification system 100, as shown in FIG. 3, each of the plurality of light transmitting body aggregates 10a to 10n is attached to the plurality of identification objects 11a to 11n, respectively. The identification objects 11a to 11n of the present embodiment are, for example, badges, and have the same basic design made up of the texture and shape of the material, the marked character string (indicated by ● ▲ ■ in FIG. 3), etc. The difference in appearance is not so large that each of the plurality of identification bodies 11a to 11n can be subjectively identified by humans). In this way, badges having the same basic design are used to indicate that a person wearing these badges, such as a company emblem, belongs to one specific organization (such as a specific company). Hereinafter, a usage example of the identification system 100 will be described.

<< First identification >>
First, any one of the identification objects 11a to 11n is fixed to, for example, a holder (not shown). The 1st irradiation means 102a is set so that the light L1 may be irradiated to the specific position in this holder at a specific angle, and the 1st irradiation means 102a is this identification target body 11 (one of identification target bodies 11a-11n) The light L1 is irradiated at a predetermined angle to a predetermined position of the light transmitting member assembly 10 (any one of the light transmitting member assembly units 10a to 10n) attached to the device.

The light receiving surface of the first light receiving means 104a is also set at a specific position and a specific angle with respect to the holder. The first light receiving means 104a is the identification object 11 (any one of the identification objects 11a to 11n). The first identification light R1 composed of the transmitted light of the light L1 of the light transmitting body assembly 10 (any one of the light transmitting body assembly 10a to 10n) attached to the light is received, and according to the received first identification light R1 The first identification information is output.

  FIG. 4 shows an example of the first identification information output from the first light receiving means 104a. In the storage means 106, as condition information representing the characteristics of the first identification information obtained when the light transmitting body assembly 10 is irradiated with the light L1, information representing the spatial distribution of the light in the red wavelength band C1, Information representing the spatial distribution of the light C2 in the yellow wavelength band, information representing the spatial distribution of the light in the blue wavelength band C3, and the like are stored in advance. Each of the light-transmitting member aggregate portions 10a to 10n is a combination of the same type of light-transmitting members 13α to 13γ. The identification unit 108 refers to the above-described condition information stored in the storage unit 106, and determines whether or not the acquired first identification information is obtained by irradiating the light transmitting body aggregates 10a to 10n with the light L1. Identify According to such an identification system 100, for example, it is possible to identify whether or not the badge placed on the holder has a feature representing the same tissue.

<< second identification >>
FIG. 5 is a schematic side view for explaining a state in which light L <b> 2 is applied to the transparent body aggregate 10 of the identification target body 11 in the identification system 100. In the identification system 100, any one of the identification objects 11a to 11n is fixed to, for example, a holder (not shown).

  The 2nd irradiation means 102b is set so that the light L2 may be irradiated to the specific position in this holder at a specific angle, and the 2nd irradiation means 102b is this identification target body 11 (any one of the identification target bodies 11a-11n). The light L2 is irradiated at a predetermined angle to a predetermined position of the light transmitting member assembly 10 (any one of the light transmitting member assembly portions 10a to 10n) attached to the device. The light L2 is not particularly limited as long as it is set according to the characteristics according to the system such as the type of the light receiving means 104b. For example, the wavelength range such as ultraviolet light and visible light is not particularly limited, and laser light may be used.

  The light receiving surface of the light receiving unit 104b is also set at a specific position and a specific angle with respect to the holder, and the light receiving unit 104b is attached to the identification target body 11 (any one of the identification target bodies 11a to 11n). The discriminating light R2 made of the reflected light of the light L2 is received by the translucent aggregate portion 10 (any of the translucent aggregate portions 10a to 10n), and the second identification information corresponding to the received identification light R2 Output.

  More specifically, in the present embodiment, the second irradiating unit 102b irradiates the light transmitting body assembly unit 10 with the light L2, and the second light receiving unit 104b changes with the scanning of the light L2. Identification information corresponding to the identification light R2 is output in time series.

  FIG. 6 shows an example of the second identification information output from the second light receiving means 104b. As shown in FIG. 6, in this embodiment, the light intensity (wavelength-dependent intensity) of each of a plurality of different specific wavelengths W1 and W2 (wavelength-dependent intensity) in the second identification light R2 is output in time series. The series information is used as identification information.

  When the light L2 is irradiated to the light transmitting body assembly 10, the identification light L2 formed by the reflected light from the light transmitting body assembly 10 is the position of the assembly 2 randomly arranged in the light transmitting body assembly 10. It depends on the state of the main surface 3 in the assembly 2 and the like. When the light L2 is scanned and applied to the light transmitting body assembly 10, the wavelength-dependent intensity of the identification light R2 changes in time series, and information of the identification light R2 (time series information in this embodiment) is Each of the plurality of light transmitting body assembly portions 10 is different.

In the storage means 106, information indicating the wavelength-dependent intensity as shown in FIG. 6 is stored in advance as condition information indicating the characteristics of the second identification information obtained when the light transmitting body assembly 10 is irradiated with the light L2. It is remembered. Prior to the use of the identification system 100, such condition information is obtained by using the second light irradiating means 102b and the light receiving means 104b. Time series change information of the second identification light L2 is acquired for all of the provided identification objects 11 (all of the identification objects 11a to 11n), and these time series change information can be stored in the memory 106 as condition information. That's fine.

  Further, in the memory 106 according to the present embodiment, in addition to the condition information stored for each of the light transmitting body assembly units 10 (transparent body assembly units 10a to 10n), a plurality of light transmitting body assembly units 10 ( Correspondences between the condition information of each of the light transmitting body aggregation portions 10a to 10n) and the attached identification objects 11a to 11n are stored in advance. For example, for each piece of condition information for each of the plurality of light transmitting body assembly portions 10 (transmission body assembly portions 10a to 10n) as shown in FIG. 5, the light transmitting body assembly portion 10 corresponding to the condition information is Information such as which person the attached identification object 11 is owned by is stored in the memory 106.

  The identification unit 108 refers to the above-described condition information stored in the storage unit 106, and the acquired second identification information is transmitted to any translucent body decoding unit (any one of the translucent body aggregation units 10a to 10n). Is obtained by irradiating and the correspondence relation is referred to. The identification means 108 by reference indicates that the acquired second identification information corresponds to any of the plurality of identification objects 11a to 11n, and the acquired identification information corresponds to which person (which person owns) Identification).

  According to such an identification system 100, for example, a person placed on a holder can identify which person owns the badge. The identification system 100 includes information output means such as a monitor (not shown). By checking the information output by the output means, an operator handling the identification system 100 selects the identification object 11 placed on the holder. It is possible to check whether a person owns it.

  If this identification system is used, an identification object can be identified with high accuracy at a relatively low cost without using an IC tag or the like. In addition, the opal composite has an excellent aesthetic appearance with a play color effect, and not only does not impair the aesthetic appearance, but also can improve the aesthetic appearance of the identification object such as a badge.

  For example, when using the translucent decoding part of the present embodiment made of an opal composite for a part of a badge such as a company emblem, the opal composite constitutes a part of a unified design having an excellent aesthetic, It is also possible to identify each badge or the like one by one with the identification system 100 in a state where personal information such as a person name and organization ID is hidden (not marked).

For example, the first irradiating means 102a and the first light receiving means 104a are arranged at the entrance of a building such as a company, and the translucent aggregate portions 10 irradiated with the first irradiating light L1 are all the same type of translucent light. By determining whether or not it is a combination of the bodies 13α to 13γ, it is possible to determine whether or not the person who owns the light transmitting body assembly unit 10 belongs to a specific organization permitted to enter. . In addition, for the specific place in the hall, the second irradiation means 102b and the second light receiving means 104b are arranged, and only a specific person identified based on the second identification information enters the room. It can also be used.

  The usage example of this system is not limited to such an example, but can be used in various other forms. For example, the condition information is not stored in the storage unit 106, but is input from the outside by an input unit (keyboard, mouse, etc.) (not shown) provided in the system 100, and the identification unit 108 receives the input. You may identify using the condition information. Thus, the configuration of the system 100 is not limited to the above embodiment.

  Next, an embodiment of a method for manufacturing the light transmitting body 13 used for the light transmitting body assembly 10 will be described. The manufacturing method of the light transmitting body 13 of the present embodiment includes a first step of obtaining a plurality of aggregates by pulverizing a thin film-like opal, a second step of dispersing the plurality of aggregates in a resin, A third step of solidifying the resin in which the body is dispersed to obtain a solidified product.

  In the first step, the thin film-like opal is pulverized to obtain a plurality of aggregates 2. First, the silica particles 1 are mixed little by little with the dispersion medium, and finally, the dispersion medium is stirred for 1 to 3 minutes so that the dispersion medium is about 1 to 5 times the silica particles 1 by mass ratio. The dispersion medium is not particularly limited as long as it is a liquid having polarity. For example, water, alcohol, a mixture thereof and the like can be mentioned. A highly polar liquid such as water is particularly preferable, and a highly volatile liquid such as alcohol can be used as the dispersion medium. Next, the dispersion liquid of the silica particles 1 is put in a burette and coated on a flat plate to form a sheet-like opal precursor. Here, it is preferable that the flat plate is hydrophilic.

  Next, the precursor on the flat plate is moved to the drying chamber so as not to break down, and the dispersion medium of the dispersion of silica particles 1 is gradually evaporated, so that the silica particles 1 precipitate and the silica particles 1 aggregate. Furthermore, it is preferable that the dispersion medium of the dispersion of silica particles 1 is gradually evaporated. The drying temperature and time may satisfy the time required for the silica particles 1 to precipitate and the silica particles 1 to aggregate, and are approximately 30 to 40 ° C. and 1 to 10 minutes.

  Next, the aggregate 2 is obtained by a pulverization method such as rubbing the dried thin film-shaped opal with a rim bar or the like from the flat plate. Alternatively, the aggregate 2 may be obtained by washing the thin film-like opal with a dispersion medium such as water or alcohol and filtering to separate the dispersion medium and the silica particles 1. Alternatively, a thin film-like opal may be put into the mill.

  Thus, if the thin film-like opal is pulverized, the aggregate 2 having a major surface can be obtained. In addition, when the opal on the thin film formed on the flat plate is preliminarily added and impregnated, the aggregate 2 is broken and the main surface 3 is damaged when the opal is rubbed off with a rim bar or the like. be able to.

  As a result, the assembly 2 can be stably manufactured with good reproducibility and efficiency, and thus mass production is possible.

  The thin film-shaped opal impregnated with the resin can maintain the main surface 3 without losing the plate shape even in the subsequent pulverization.

  When the aggregate 2 that is not impregnated with the resin is included in the opal composite 10, an idle color effect having more various colors can be obtained.

  Such a pulverized aggregate 2 may be classified so that the particle diameters are uniform. As a classification method, since the aggregates 2 stick to each other when filtered with a filter, it is preferable to classify the dispersion in which the aggregates 2 are dispersed in water by centrifugation and then store them in a stirred dispersion medium. .

  In the second step and the third step, the plurality of aggregates 2 are impregnated with a dye exhibiting a specific color such as red, yellow, or blue, and are dispersed in the resin 4 and solidified. In the dispersion step, when the two are not mixed due to the difference in specific gravity between the aggregate 2 and the resin 4, the aggregate 2 is dispersed while stirring or convection of the resin 4, or further, the resin 4 is solidified by gradually heating. The solidified product may be used. Through such a dispersion step, the translucent bodies 10 whose main surfaces 3 face in different directions are obtained.

  The obtained opal composite may use buffing as the final surface finish, but the presence or absence of polishing and the type of polishing are not limited thereto. Alternatively, the surface can be smoothed by applying varnish or the like without polishing. Such an opal composite can be used as the translucent body 13 by subjecting such an opal composite to a process of slicing with a wire saw or the like to form a sheet.

  FIG. 7 is an electron micrograph of the translucent body 13 obtained through such steps. In FIG. 7, the portion that appears white is the assembly 2, and the portion that appears black is resin. Thus, it can be seen that the aggregate 2 is dispersed in the resin. The arrangement and the like of the assembly 2 in the translucent body 13 are random, and the identification information obtained by the identification system 100 is different, although there is a sense of unity in appearance.

  While the embodiments and examples of the present invention have been described above, the present invention is not limited to the above-described embodiments and examples. It goes without saying that various improvements and modifications may be made to the present invention without departing from the gist of the present invention.
