  2. Description of the Related Art Conventionally, position indication plates that are attached to outdoor or indoor installations such as boundary sign explicit sign boards and meter reading meter sign boards are known. For example, in Patent Document 1, a white plastic plate is bonded to one side of a pressure-sensitive adhesive sheet in which a pressure-sensitive adhesive layer is formed on both sides of a plastic mat, and the position and An outdoor position display plate having a display surface on which management data is displayed with a two-dimensional digital data code having a dot-like light and dark pattern is disclosed.

  By the way, such a two-dimensional code pattern is formed at a position that is easy for humans to visually recognize, such as the ground such as a road or the wall surface of a building, and by encoding position information in this two-dimensional code pattern, It is possible to provide position information regarding the current position to a person who travels by car or a pedestrian. For example, it provides position information with position accuracy of several tens of centimeters that cannot be provided by the GPS system, and accurate position information even in underground and buildings where radio waves from satellites do not reach. It becomes possible.

  Since the two-dimensional code pattern needs to be decoded after being read by the CCD, it is necessary to form the pattern with a certain degree of accuracy. As a result, even when the two-dimensional code pattern is formed on the ground surface, the wall surface, etc., the two-dimensional code pattern is formed by an accurate method such as printing.

  However, when a two-dimensional code pattern is formed on the ground, wall surface, etc. by printing, the two-dimensional code pattern is relatively simple because the heels of automobile tires and pedestrian shoes directly hit the two-dimensional code pattern. Will be hurt. If the two-dimensional code pattern is damaged, the position information encoded on the two-dimensional code pattern cannot be decoded.

  As a result, the two-dimensional code pattern cannot be expected to be used for a long time.

Embodiment 1 FIG.
FIG. 1 is an explanatory view of an embedded state showing an embedded member according to Embodiment 1 of the present invention. The embedded member includes a rock 1 as a plate-like member, a transparent member 2, a reflecting member 3, and a protective frame member 4.

  FIG. 2 is a top view showing the stone 1 in FIG. The stone 1 is made of concrete in a substantially square flat plate shape. A cross-shaped reference point mark (auxiliary point) 5 is formed at the center of the upper surface of the stone 1. A tile 6 is disposed in a portion adjacent to the reference point mark 5.

  The tile 6 has a tile base 7 having a substantially square plate shape. The tile base 7 is made of ceramic. Note that the tile base 7 may be formed in other shapes, for example, a regular polygonal shape such as a substantially hexagonal shape, or other shapes. A seal 8 is attached to the surface of the tile base 7. A two-dimensional code pattern portion is printed on the sticker 8.

  The two-dimensional code constituting the two-dimensional code pattern part includes a stack type two-dimensional code such as Code 49 and PDF 417, and a matrix type two code such as Veri code, data matrix, QR (Quick Response) code, and micro QR code. There is a dimension code. The QR code has a feature that data can be restored even if 30% of the pattern is dirty or missing, and is suitable as a two-dimensional code used for the tile 6 of the present invention.

  In the first embodiment, a two-dimensional code pattern portion in which two colors of white and black are combined is printed on the seal 8. Note that only one of the two colors for constituting the two-dimensional code pattern is printed on the sticker 8 as a two-dimensional code pattern portion, and the other color constituting the two-dimensional code pattern is substituted with the color of the sticker 8. Thus, a two-dimensional code pattern may be formed on the tile 6. Further, only one of the two colors for forming the two-dimensional code pattern is printed on the sticker 8 as a two-dimensional code pattern portion, and the sticker 8 is made colorless and transparent, and the other color constituting the two-dimensional code pattern is printed. A two-dimensional code pattern may be formed on the tile 6 by substituting the color of the tile base 7.

  The two-dimensional code pattern formed on the tile 6 according to the first embodiment includes two pieces of data including position information indicating the place where the embedded member is installed (more precisely, position information where the reference point described later is installed). Dimension coded. The position information includes, for example, position information in the horizontal direction, position information in the vertical direction, and information related to a reference for the position information. As the position information in the horizontal direction, for example, information such as a latitude / longitude value, an address or a lot number exists. As the position information in the vertical direction, there are information such as altitude, the number of floors (including the basement), and the height from the reference plane. In addition, as information on the standard of the position information, for example, when latitude and longitude are horizontal position information, whether it is the value of latitude and longitude in the world geodetic system, or latitude in other geodetic systems There are information indicating whether the value is a longitude value, information on a measurement reference point, and the like.

  Note that when an address or the like is used as horizontal position information, there is little risk of misinterpretation of the horizontal or vertical position information reference, and information regarding the position information reference may be omitted. Further, the position information is not limited to the one having both the position information in the horizontal direction and the position information in the vertical direction, and has only the position information in the horizontal direction or only the position information in the vertical direction. There may be.

  In addition, a larger amount of information can be coded into the two-dimensional code pattern than, for example, a barcode pattern. Therefore, for example, the survey information of the area where the embedded member is installed, the information about the area where the embedded member is installed, the peripheral equipment and the facility information of the place where the embedded member is installed, and the position information are encoded into a two-dimensional code pattern. May be. The survey information of the area where the buried member is installed includes, for example, the boundary of the area, the topography, the area, the survey date, the plot number, and the point name.

  FIG. 3 is a perspective view showing the reflecting member 3 and the transparent member 2 in FIG.

  The transparent member 2 is formed by forming a transparent material such as glass, acrylic resin, polycarbonate resin or the like into a substantially quadrangular prism shape. The transparent member 2 may be formed of a translucent material such as vinyl chloride resin. Further, a reference point mark 9 (reference point) having the same cross shape as the reference point mark 5 of the rock stone 1 is formed on the upper surface of the transparent member 2.

  The reflecting member 3 is formed of a metal material in a substantially quadrangular prism shape, and a substantially quadrangular prism-shaped through hole 3a is formed along the column axis direction. Further, the inner surface 3b of the reflecting member 3 formed by the through hole 3a is subjected to mirror finishing or plating finishing.

  The protective frame member 4 shown in FIG. 1 is made of concrete in a substantially square flat plate shape. A rectangular through-hole 4 a larger than the reflecting member 3 is formed at the center of the protective frame member 4. The protective frame member 4 is cut obliquely from the center of the upper surface to the side surface.

  And the stone 1, the transparent member 2, the reflection member 3, and the protective frame member 4 of these embedded members are embedded in the ground as shown in FIG. That is, the stone 1 is embedded substantially horizontally in the ground with the top surface on which the tiles 6 are disposed on the ground surface side. Underneath the stone 1 is gravel for leveling and draining the stone 1. Further, as shown in FIG. 3, the reflecting member 3 in which the transparent member 2 is inserted into the through hole 3 a is placed on the stone 1 so that the reference point mark 9 of the transparent member 2 overlaps the reference point mark 5 of the stone 1. It is buried in the state of being placed. Thereby, the transparent member 2 overlaps the range shown by the dotted line frame 10 of FIG. In this placement state, the upper ends of the transparent member 2 and the reflecting member 3 are substantially the same height as the ground. The protective frame member 4 is embedded near the ground surface so that the reflecting member 3 is in the through hole 4 a and the upper surface is higher than the upper ends of the transparent member 2 and the reflecting member 3.

  FIG. 4 is a block diagram showing the mobile phone terminal 16 that captures a two-dimensional code pattern.

  The mobile phone terminal 16 includes a CCD (Charge Coupled Device) camera 11, a decoding unit 12, a liquid crystal monitor 13, a telephone unit 14, and a control unit 15. The CCD camera 11 has a plurality of light receiving elements arranged two-dimensionally, and generates luminance distribution data based on the arrangement of the plurality of light receiving elements. The decoding unit 12 extracts a two-dimensional code pattern included in the luminance distribution data, decodes the two-dimensional code from the extracted two-dimensional code pattern, and restores the data. The liquid crystal monitor 13 displays the data restored by the decoding unit 12.

  Then, as shown in FIG. 5, the user of the mobile phone terminal 16 photographs the transparent member 2 with the CCD camera 11 of the mobile phone terminal 16 from directly above. Note that the user aligns the CCD camera 11 of the mobile phone terminal 16 so that the reference point mark 9 on the upper surface of the transparent member 2 overlaps the reference point mark 5 of the rock stone 1 in the image displayed on the liquid crystal monitor 13. You can take a picture.

  The CCD camera 11 generates luminance distribution data including a two-dimensional code pattern of the rock 1 observed through the transparent member 2. The decoding unit 12 extracts a two-dimensional code pattern from the luminance distribution data, and restores data encoded in the extracted two-dimensional code pattern. The liquid crystal monitor 13 displays the restored data.

  Thereby, the user of the mobile phone terminal 16 can know the position information of the embedded member encoded in the two-dimensional code pattern of the embedded member, that is, the current position information where the pedestrian has photographed the embedded member. . For example, when the two-dimensional code pattern shown in FIG. 6 is formed on the tile 6 of the rock stone 1 and this two-dimensional code pattern is photographed, as shown in FIG. (Direction) coordinates, information on the coordinate system, image number, and measurement date can be obtained.

  As described above, in the first embodiment, the two-dimensional code pattern and the reference point mark 5 in which the position information is encoded are formed on the stone 1 embedded in the ground, and the two-dimensional code pattern and the reference point mark 5 are formed. A transparent member 2 made of a transparent material is embedded between the ground and the ground. Thereby, the two-dimensional code pattern and the reference point mark 5 embedded in the ground can be observed from the ground via the transparent member 2 and can be used.

  Moreover, since the two-dimensional code pattern and the reference point mark 5 itself are embedded in the ground, the tires of automobiles, the heels of human shoes, and the like do not come into direct contact with them. Therefore, the two-dimensional code pattern and the reference point mark 5 can be used over a long period of time compared to the case where the two-dimensional code pattern and the reference point mark 5 are formed on the ground.

  In the first embodiment, the transparent member 2 is inserted into the reflecting member 3 having the inner surface 3b that has been subjected to mirror finishing or plating finishing. As a result, external light and the like are reflected by the inner side surface 3b of the reflecting member 3, so that even if the transparent member 2 is long and the stone 1 is buried to a depth of about 60 cm, for example, The two-dimensional code pattern and the reference point mark 5 are brightly illuminated. Further, since the stone 1 is buried deeply, it is less affected by the load and vibration of an automobile passing through the ground, and the stone 1 is less than the case where the stone 1 is buried shallow near the ground surface. It is buried in a stable state for a longer period. Instead of applying a mirror finish or plating finish to the inner surface 3b of the reflecting member 3, a fluorescent paint or the like may be applied to the inner surface 3b of the reflecting member 3. Alternatively, an optical fiber or the like may be embedded separately from the transparent member 2 from the ground surface to the stone 1 and the two-dimensional code pattern and the reference point mark 5 may be illuminated with light introduced from the optical fiber.

  In the first embodiment, the embedded member is embedded in the ground. However, the embedded member may be embedded in, for example, a wall or a ceiling of a building.

  As a system for knowing the current position, GPS (Global Positioning System) is widely used. However, if GPS cannot capture four satellites, it cannot know the exact position. Even if four satellites can be captured, a position error of about 10 m remains. In contrast, by providing the embedded member with position information encoded in two dimensions, it is possible to provide accurate position information even in places where satellites cannot be supplemented, such as in buildings or underground shopping streets. Can do. In addition, for example, the tiles 6 are installed at intervals of 1 m, or the tiles 6 are continuously arranged and arranged to provide positional information with a positional accuracy of several centimeters to several tens of centimeters.

Embodiment 2. FIG.
FIG. 8 is an explanatory diagram of an embedded state showing the embedded member according to Embodiment 2 of the present invention. The burying member includes a rock 1 as a plate-like member, a cylindrical member 21, and a protective frame member 4. The stone 1 and the protective frame member 4 have the same configuration as the components of the same name according to the first embodiment, and the same reference numerals as those of the same name of the first embodiment are attached and description thereof is omitted.

  FIG. 9 is an exploded perspective view showing the cylindrical member 21 in FIG. The cylindrical member 21 includes a cylindrical portion 21a, an upper lens 21b, and a lower lens 21c.

  The cylindrical portion 21a is formed by forming a metal material into a substantially cylindrical shape, and a substantially cylindrical through hole 21d is formed along the axial direction of the cylinder. The inner surface 21e of the cylindrical portion 21a is subjected to mirror finishing or plating finishing.

  The upper lens 21b is a lens fitted to one end side of the through hole 21d of the cylindrical portion 21a, and is formed of a transparent material such as glass, acrylic resin, polycarbonate resin, or a translucent material such as vinyl chloride resin. A reference point mark (reference point) 22 having the same cross shape as the reference point mark 5 of the rock stone 1 is formed on the upper lens 21b.

  The lower lens 21c is a lens fitted to the other end side of the through hole 21d of the cylindrical portion 21a, and is formed of a transparent material such as glass, acrylic resin, or polycarbonate resin, or a translucent material such as vinyl chloride resin. The

  As shown in FIG. 8, the stone 1 is embedded substantially horizontally in the ground with the upper surface on which the tiles 6 are disposed being on the ground surface side. Underneath the stone 1 is gravel for leveling and draining. The cylindrical member 21 is placed on the stone 1 so that the reference point mark 22 overlaps the reference point mark 5 of the stone 1 and the lower lens 21c is on the stone 1 side. Buried. Thereby, the through-hole 21d of the cylindrical member 21 overlaps the range shown in the dotted frame 23 of the drawing showing the rock 1 of FIG. In this placement state, the upper end of the cylindrical member 21 on which the upper lens 21b is provided is substantially the same height as the ground. The protective frame member 4 is embedded near the ground surface so that the cylindrical member 21 is in the through hole 4 a and the upper surface thereof is higher than the upper end of the cylindrical member 21.

  When the CCD camera 11 of the mobile phone terminal 16 shown in FIG. 4 is placed and photographed directly above the cylindrical member 21, the CCD camera 11 is observed two-dimensionally through the upper lens 21b and the lower lens 21c. Brightness distribution data including a code pattern is generated. The decoding unit 1212 extracts a two-dimensional code pattern from the luminance distribution data, and restores data encoded in the extracted two-dimensional code pattern. The liquid crystal monitor 13 displays the restored data. Thereby, the user of the mobile phone terminal 16 shown in FIG. 4 can know the position information of the embedded member encoded in the two-dimensional code pattern of the embedded member, that is, the current position information of the pedestrian.

  As described above, in the second embodiment, the two-dimensional code pattern and the reference point mark 5 in which the position information is encoded are formed on the stone 1 embedded in the ground, and the two-dimensional code pattern and the reference point mark 5 are formed. The cylindrical member 21 is embedded between the ground and the ground. Thereby, the two-dimensional code pattern and the reference point mark 5 embedded in the ground can be observed from the ground via the upper lens 21b and the lower lens 21c of the cylindrical member 21, and can be used.

  Moreover, since the two-dimensional code pattern and the reference point mark 5 itself are embedded in the ground, the tires of automobiles, the heels of human shoes, etc. do not come into direct contact. Therefore, compared to the case where the two-dimensional code pattern and the reference point mark 5 are formed on the ground, the two-dimensional code pattern and the reference point mark 5 can be installed so as to be usable over a long period of time.

  In the second embodiment, the inner surface 21e of the cylindrical member 21 is formed with a reflecting surface that reflects light. Thereby, since the inner surface 21e of the cylindrical member 21 reflects external light or the like, the cylindrical member 21 becomes long and the rock 1 is buried at a depth of about 60 cm in the ground, for example. The two-dimensional code pattern and the reference point mark 5 are brightly illuminated. Further, since the rock 1 is buried deeply, it is less affected by the load or vibration of an automobile passing through the ground, and is stable for a longer period than when the rock 1 is buried near the surface. Can be embedded in A fluorescent paint may be applied to the inner side surface 21e of the cylindrical member 21. Alternatively, an optical fiber or the like may be embedded separately from the cylindrical member 21 from the ground surface to the stone 1 and the two-dimensional code pattern and the reference point mark 5 may be illuminated with light introduced from the optical fiber.

The lid member 32 includes a circular lid portion 32a having substantially the same size as the opening 31c of the cylindrical portion 31a, and a bearing portion 32b attached to the lid portion 32a. A bearing portion 32b is attached to be rotatable around the rotation shaft 31d. Since the lid portion 32a of the lid member 32 overlaps the opening 31c of the cylindrical portion 31a, the opening 31c of the cylindrical portion 31a is closed by the lid member 32, and the cavity 31b of the cylindrical portion 31a is sealed. The lid member 32 may be attached to the cylindrical member 31 so as to be openable and closable by a screw method by forming a screw thread on the lid portion 32a and forming a thread groove on the inner surface 31e of the cylindrical portion 31a.

  FIG. 13 is a bottom view showing the back surface of the lid portion 32a in FIG. A seal 36 is attached to the back surface of the lid portion 32a. On the seal 36, a two-dimensional code pattern portion 36b in which two colors of white and black are combined is printed. In the two-dimensional code pattern portion 36b, data including position information indicating the place where the embedded member is installed (more precisely, information on the installation position of the reference point) is converted into a two-dimensional code.

  FIG. 14 is an exploded view showing the configuration of the internal unit 33 in FIG. 11. The internal unit 33 includes a cap member 37 as a part of the upper cylindrical part, a cup member 38 as a part of the upper cylindrical part, and a leg member 39 as the lower cylindrical part. The cap member 37, the cup member 38, and the leg member 39 may be formed of a material such as vinyl chloride.

  The cup member 38 is formed on the inner side surface 31e of the cup body 38a near the opening 31c of the cavity 31b, the columnar cavity 38b formed from the upper surface of the cup body 38a to the inside, and the cup body 38a formed in a cylindrical shape. And a screw thread 38d formed on the outer peripheral bottom of the cup body 38a.

  The cap member 37 includes a cap main body 37a formed in a disk shape having substantially the same outer periphery as the cup main body 38a, a convex portion 37b protruding from the back surface of the cap main body 37a, and a thread 37c formed on the outer periphery of the convex portion 37b. And having. FIG. 15 is a top view showing the surface of the cap member 37 in FIG. On the upper surface of the cap body 37a, the same coordinate point mark (auxiliary point) 40 as the coordinate point mark 35 formed on the surface of the lid portion 32a is formed, and the seal 36 adhered to the back surface of the lid portion 32a; The same seal 41 is pasted. On the seal 41, the same two-dimensional code pattern portion 41a as the two-dimensional code pattern portion 36b formed on the back surface of the lid portion 32a is printed. A handle member 42 having a half-ring shape is attached to the upper surface of the cap body 37a.

  The leg member 39 has a leg main body 39a formed in a hollow cylindrical shape, and a screw groove 39b formed in the inner peripheral surface of the leg main body 39a.

  In the cavity 31b of the cup member 38, a transmitter 43 having information encoded in the two-dimensional code pattern of the lid member 32 is disposed. In addition, for example, in the cavity 31b of the cup member 38, a plate-like member having the same two-dimensional code pattern as the two-dimensional code pattern of the lid member 32 is disposed, or the two-dimensional code pattern of the lid member 32 is provided. A semiconductor recording device having encoded information may be provided.

  The rock stone 34 is buried substantially horizontally in the ground. Further, the cylindrical member 31 is embedded on the stone 34 so that the opening 31c of the cylindrical member 31 is substantially the same height as the ground surface.

  After the transmitter 43 is placed in the cavity 31b, the cup member 38 and the cap member 37 are connected by a screw method, and the cup member 38 and the leg member 39 are connected by a screw method. Thereby, the cylindrical internal unit 33 is formed. The internal unit 33 is inserted into the cavity 31 b of the cylindrical member 31 in such a posture that the cap member 37 is on the opening 31 c side of the cylindrical member 31. After the internal unit 33 is inserted into the tubular member 31, the lid member 32 is tilted to close the cavity 31 b of the tubular member 31 with the lid member 32. In this state, since the opening 31 c is blocked by the lid member 32, it is difficult for water or mud to enter the cavity 31 b of the tubular member 31. In addition, a hole may be formed in the bottom of the cylindrical member 31 and gravel may be laid under the rock stone 34 or a drain pipe may be provided so that water or the like does not accumulate in the cavity 31b of the cylindrical member 31.

  Then, when the lid member 32 is opened and the two-dimensional code pattern portion 36b formed on the back surface of the lid member 32 or the upper surface of the internal unit 33 is photographed by the CCD camera 11 of the mobile phone terminal 16 shown in FIG. 11 generates luminance distribution data including a two-dimensional code pattern. The decoding unit 12 extracts a two-dimensional code pattern from the luminance distribution data, and restores data encoded in the extracted two-dimensional code pattern. The liquid crystal monitor 13 displays the restored data. Thereby, the user of the mobile phone terminal 16 shown in FIG. 4 can know the position information of the embedded member encoded in the two-dimensional code pattern of the embedded member, that is, the current position information of the pedestrian.

  As described above, according to the third embodiment, the reference point mark 35 is formed on the front surface of the lid member 32, and the two-dimensional code pattern in which the position information is encoded is formed on the back surface of the lid member 32. . Further, the internal unit 33 disposed in the cavity 31b of the cylindrical member 31 has the same reference point mark 40 on the front surface of the lid member 32 as the reference point mark 40 and the same two-dimensional code pattern on the back surface of the lid member 32. A two-dimensional code pattern is formed. Therefore, even if the two-dimensional code pattern and the reference point mark 35 of the lid member 32 are damaged by a car tire or a person's shoes, the two-dimensional code pattern and the reference point mark 40 of the internal unit 33 remain. Therefore, it is possible to install the two-dimensional code pattern and the reference point mark so that they can be used over a long period of time, compared to the case where the two-dimensional code pattern and the reference point mark are formed only on the ground or the wall surface.

  According to the third embodiment, the two-dimensional code pattern and the reference point mark 40 of the internal unit 33 are on the opening 31c side of the cylindrical member 31, and the inner surface 31e of the cylindrical member 31 reflects light. Is formed. Accordingly, the two-dimensional code pattern and the reference point mark 40 of the internal unit 33 are brightly illuminated by the light reflected by the inner side surface 31e of the cylindrical member 31. As a result, the two-dimensional code pattern and the reference point mark 40 formed in the internal unit 33 can be observed and used while the internal unit 33 is disposed in the cavity 31b.

  According to the third embodiment, the hollow 31b of the cylindrical member 31 is formed in a columnar shape, and the internal unit 33 is connected to the cap member 37, the cup member 38, and the leg member 39 by a screw method so as to be divided. 37, the two-dimensional code pattern of the internal unit 33 and the reference point mark 40 are formed. Thereby, for example, the depth from the opening 31c of the cylindrical member 31 to the two-dimensional code pattern of the internal unit 33 and the reference point mark 40 can be easily adjusted by replacing the leg member 39 with a different length. Can do. As a result, for example, the length of the cylindrical member 31 is increased to increase the depth of the embedded cylindrical member 31, and the embedded member is stably embedded for a longer period of time, while the two-dimensional structure of the internal unit 33 is increased. The code pattern and the reference point mark can be easily adjusted to the height that is brightly illuminated according to the installation environment of the embedded member.

  According to the third embodiment, the hollow 31 b of the cylindrical member 31 is formed in a columnar shape, and the internal unit 33 has the handle member 42. Therefore, the internal unit 33 inserted into the tubular member 31 can be easily pulled out from the tubular member 31 by turning the internal unit 33 while pulling the handle member 42.

  According to the third embodiment, the internal unit 33 is formed so as to be capable of being divided into a cap member 37 and a cup member 38, and is encoded in the two-dimensional code pattern of the lid member 32 in the cavity 31 b of the cup member 38. A transmitter 43 having information is arranged. As a result, even if the two-dimensional code pattern of the lid member 32 and the two-dimensional code pattern of the internal unit 33 are both damaged, the information encoded in the two-dimensional code pattern is stored in the internal unit 33. It can be obtained from the transmitter 43 arranged. Therefore, the embedded member can be used over a longer period.

Embodiment 4 FIG.
FIG. 16 is an embedded state explanatory view showing an embedded member according to Embodiment 4 of the present invention. The embedded member includes a tile 51 and a protection plate 52.

  FIG. 17 is a front view showing the tile 51 in FIG. The tile 51 is made of earthenware and is formed in a substantially square flat plate shape. Note that the tile 51 may be made of plastic or metal. A seal 51 a is stuck on the surface of the tile 51. A two-dimensional code pattern portion 51b in which two colors of white and black are combined is printed on the seal 51a. In the two-dimensional code pattern portion 51b, data including position information indicating a place where the embedded member is installed is converted into a two-dimensional code.

The protection plate 52 is formed of rubber, metal, concrete, or the like, and has a substantially flat plate portion 52a, an opening portion 52b formed at the center of the flat plate portion 52a, and a flat plate portion 52a around the periphery of the opening portion 52b. A projecting portion 52c erected on the surface of the flat plate portion 52a, and an anchor member 52d erected on the back surface of the flat plate portion 52a around the periphery of the opening 52b. The opening 52 b is formed to be slightly smaller than the tile 51. The protrusion 52c is formed so that its cross section has a trapezoidal shape.

  The tile 51 is embedded so that the two-dimensional code pattern portion 51b is exposed to the ground. The protection plate 52 is embedded by piercing the anchor member 52d into the ground so that the opening 52b overlaps the two-dimensional code pattern portion 51b. Accordingly, the range of the dotted frame 53 in FIG. 17 including the two-dimensional code pattern portion 51b of the tile 51 can be observed from the opening portion 52b of the protection plate 52.

  When the two-dimensional code pattern portion 51b that can be observed from the opening 52b of the protective plate 52 is photographed by the CCD camera 11 of the mobile phone terminal 16 shown in FIG. 4, the CCD camera 11 has a luminance distribution including the two-dimensional code pattern. Generate data. The decoding unit 12 extracts a two-dimensional code pattern from the luminance distribution data, and restores data encoded in the extracted two-dimensional code pattern. The liquid crystal monitor 13 displays the restored data. Thereby, the user of the mobile phone terminal 16 shown in FIG. 4 can know the position information of the embedded member encoded in the two-dimensional code pattern of the embedded member, that is, the current position information of the pedestrian.

  As described above, in the fourth embodiment, a two-dimensional code pattern in which data including position information indicating a place where an embedded member is installed is two-dimensionally encoded is formed on the tile 51, and the two-dimensional code pattern is formed in the opening 52b. A protective plate 52 is placed on the tile 51 so that it can be observed from above. Therefore, the two-dimensional code pattern of the tile 51 is surrounded by the protection plate 52, and the protruding portion 52c of the protection plate 52 is erected around the two-dimensional code pattern. Therefore, it becomes difficult for a car tire or a heel of a person's shoes to directly contact the two-dimensional code pattern. Therefore, it is possible to install the two-dimensional code pattern so that it can be used over a long period of time, compared to the case where the two-dimensional code pattern is simply formed only on the ground or the wall surface.

  In the fourth embodiment, an anchor member 52d is provided on the protective plate 52, and the protective plate 52 is fixed alone by the anchor member 52d. Therefore, the protection plate 52 and the tile 51 on which the two-dimensional code pattern is formed are independently embedded in the ground, and even if force is applied to the protection plate 52 by a car tire or a person's shoes, The force hardly acts on the tile 51. As a result, the two-dimensional code pattern can be installed to be usable for a longer period of time.

Therefore, it is possible to install the two-dimensional code pattern so that it can be used over a long period of time, compared to the case where the two-dimensional code pattern is simply formed only on the ground or the wall surface.

  In the fifth embodiment, the thickness of the tile 63 is thinner than the depth of the recess 62 b of the frame-like member 62. Accordingly, the tile 63 on which the two-dimensional code pattern is formed is embedded with the surface thereof being retracted into the recess 62b. Therefore, it becomes difficult for a car tire or a heel of a person's shoes to directly contact the two-dimensional code pattern. Therefore, it is possible to install the two-dimensional code pattern so that it can be used over a long period of time, compared to the case where the two-dimensional code pattern is simply formed only on the ground or the wall surface.

Further, when the tile 176 and the protection plate 181 can be integrated with the cover member 186 by the caulking material or the clay-like material, the bottom plate 171 may not be used.

  Next, the nail 196 is passed through the two second through holes 190 of the cover member 186 and the two through holes 173 of the bottom plate 171 in this way, and the cover member 186 is fixed to a wall surface or the like with the nails 196. Instead of the nail 196, screws or the like may be passed through the two second through holes 190 of the cover member 186 and the two through holes 173 of the bottom plate 171. Further, the number of points to be stopped by the nail 196 may be one or three or more.

  Then, by photographing the two-dimensional code pattern portion 179 of the tile 176 with the CCD camera 11 of the mobile phone terminal 16 shown in FIG. 4, the user can embed it in the two-dimensional code pattern of the embedded member. The position information of the member, that is, the current position information of the pedestrian can be known.

  As described above, in the thirteenth embodiment, the two-dimensional code pattern can be formed on the floor surface or the like in a state where the two-dimensional code pattern of the tile 176 is covered with the protective plate 181 and the cover member 186. Therefore, it is possible to install the two-dimensional code pattern so that it can be used over a long period of time, compared to the case where the two-dimensional code pattern is simply formed only on the ground or the wall surface.

  Moreover, in the thirteenth embodiment, the tile 176 having the two-dimensional code pattern portion 179 can be easily obtained simply by fixing the cover member 186 to the wall surface or the like using the second through-hole 190 formed in the cover member 186 itself. Can be installed.

  In addition, the tile 176, the protection plate 181 and the cover member 186 are stopped by the nail 196 or the like in this way, so that existing tiles 176, the protection plate 181 and the nail 196 can be used. This can greatly reduce the cost of creating the embedded member.

  In the twelfth embodiment, cross reference position marks 201 and 202 are formed on one of the two nails 196 and the cover member main body 187 around the nail 196. In the two-dimensional code pattern of the two-dimensional code pattern unit 179, data including the position information of the reference position marks 201 and 202 is converted into a two-dimensional code. Even if the reference position mark is formed as an arrow mark 203 at another corner of the cover member main body 187 where the second through-hole 190 is not formed as shown in FIG. As shown in B), it may be formed as an arrow mark 204 toward one side of the cover member main body 187. FIG. 44 is a front view showing two modified examples of the cover member 186 in FIG.

  The embedded member according to the present invention can be embedded in a road, a building or the like to provide position information.
