  FIG. 1 is a diagram for explaining a card usage state and a card game apparatus according to the present invention.

  As shown in the figure, the card is used when a game is played on a card game device. In this card game apparatus, the entire lower surface of the card arrangement panel is imaged by one sensor unit (imaging means). In the space on the lower surface of the card placement panel, an IRLED that irradiates the dot pattern on the card surface on the panel surface with irradiation light at a position that avoids imaging light from the panel surface of the sensor unit, and this irradiation light on the lower surface of the panel A diffusion filter for diffusing is provided.

  The diffusion filter is provided in a frame plate shape so as to protrude from the side wall portion constituting the apparatus housing to the lower surface space of the card placement panel. This diffusion filter is made of a transparent or translucent glass plate or a synthetic resin plate, and has a satin finish on one surface thereof. The irradiation light of the IRLED is diffused through this diffusion filter, so that the entire lower surface of the card arrangement panel can be irradiated with the irradiation light. And when this card | curd is mounted on the card | curd arrangement | positioning panel, this irradiation light is irradiated to this card | curd surface, and the reflected light is imaged with a sensor unit.

  Although not shown, the sensor unit is connected to a central processing unit (MPU) having a frame buffer via a cable. This central processing unit (MPU) is connected to a game central processing unit, and a display and a speaker are connected to the game central processing unit. When the sensor unit and the central processing unit (MPU) read the dot pattern printed on the card, the dot pattern is converted into a code value, and an image / moving image corresponding to the code value is displayed on the display device.

  Next, the dot pattern used for the card of this embodiment will be described.

  The dot pattern used for the card in the present embodiment is the dot pattern shown in FIGS. 10 to 11. First, the basic principle on which the dot pattern is based will be described with reference to FIGS. 2 to 9.

  FIG. 2 is an explanatory diagram showing GRID1, which is an example of the dot pattern of the present invention.

  In these drawings, vertical and horizontal grid lines are provided for convenience of explanation, and are not present on the actual print surface. The key dots 2, information dots 3, reference grid point dots 4 and the like constituting the dot pattern 1 are made of invisible ink or carbon ink that absorbs infrared light when the scanner as imaging means has infrared irradiation means. It is desirable that it is printed.

  FIG. 3 is an enlarged view showing an example of a dot pattern information dot and a bit display of data defined therein. FIGS. 4A and 4B are explanatory diagrams showing information dots arranged around key dots.

  The information input / output method using a dot pattern according to the present invention includes generation of a dot pattern 1, recognition of the dot pattern 1, and means for outputting information and a program from the dot pattern 1. That is, the dot pattern 1 is captured as image data by the camera, the reference grid point dot 4 is extracted first, and then the key dot 2 is extracted because the dot is not originally placed at the position where the reference grid point dot 4 is located. Next, the information dot 3 is extracted and digitized to extract an information area to digitize the information, and information and a program are output from the dot pattern 1 based on the numerical information. For example, information or a program such as voice is output from the dot pattern 1 to an information processing apparatus, personal computer, PDA, mobile phone or the like.

  The dot pattern 1 according to the present invention is generated in accordance with a predetermined rule for fine dots, that is, key dots 2, information dots 3, and reference lattice point dots 4, in order to recognize information such as voice by a dot code generation algorithm. Arrange. As shown in FIG. 2, the block of the dot pattern 1 representing information has a 5 × 5 reference grid point dot 4 on the basis of the key dot 2, and the center of the center surrounded by the four reference grid point dots 4. Information dots 3 are arranged around the virtual grid point 5. Arbitrary numerical information is defined in this block. In the illustrated example of FIG. 2, a state is shown in which four blocks (inside the thick line frame) of the dot pattern 1 are arranged in parallel. Of course, the dot pattern 1 is not limited to four blocks.

  One corresponding information and program can be output to one block, or one corresponding information and program can be output to a plurality of blocks.

When the dot pattern 1 is captured by the camera as the image data, the reference grid point dot 4 corrects distortion of the lens of the camera, imaging from an oblique direction, expansion / contraction of the paper surface, curvature of the medium surface, and distortion during printing. Can do. Specifically, a correction function (X _n , Y _n ) = f (X _n ′, Y _n ′) for converting the distorted four reference grid point dots 4 into the original square is obtained, and the same function is obtained. Then, the information dot 3 is corrected to obtain a correct information dot 3 vector.

  If the reference grid dot 4 is arranged in the dot pattern 1, the image data obtained by capturing the dot pattern 1 with the camera corrects the distortion caused by the camera. Even when the image data of the dot pattern 1 is captured by the camera, it can be accurately recognized. Even if the camera is tilted and read with respect to the surface of the dot pattern 1, the dot pattern 1 can be accurately recognized.

  As shown in FIG. 2, the key dot 2 is a dot in which four reference grid point dots 4 at the corners of the four corners of the block are shifted in a certain direction. The key dot 2 is a representative point of the dot pattern 1 for one block representing the information dot 3. For example, the reference grid point dots 4 at the corners of the four corners of the block of the dot pattern 1 are shifted upward by 0.1 mm. When the information dot 3 represents the X and Y coordinate values, the coordinate point is a position where the key dot 2 is shifted downward by 0.1 mm. However, this numerical value is not limited to this, and can be changed according to the size of the block of the dot pattern 1.

  The information dot 3 is a dot for recognizing various information. The information dot 3 is arranged around the key dot 2 as a representative point, and the center surrounded by the four reference grid point dots 4 is set as a virtual grid point 5 and expressed as a vector using this as a starting point. Arranged at the end point. For example, the information dot 3 is surrounded by the reference grid point dot 4, and as shown in FIG. 3A, a dot 0.1 mm away from the virtual grid point 5 has a direction and length expressed by a vector. Therefore, it is rotated 45 degrees clockwise and arranged in 8 directions to represent 3 bits. Accordingly, 3 bits × 16 pieces = 48 bits can be expressed by one block of dot pattern 1.

FIG. 3B is a method of defining information dots 3 having 2 bits for each grid in the dot pattern of FIG. 2, and each 2-bit information is shifted by shifting the dots in the + direction and the x direction. Defined. Thus, although 48-bit information can be originally defined, data can be given every 32 bits by dividing according to usage. A maximum of 2 ¹⁶ (about 65000) dot pattern formats can be realized by combining the + direction and the X direction.

  Note that the present invention is not limited to this, and it is possible to represent 4 bits by arranging in 16 directions, and it is needless to say that various changes can be made.

  The diameter of the key dot 2, the information dot 3 or the reference grid point dot 4 is preferably about 0.05 mm in consideration of appearance, printing accuracy with respect to paper quality, camera resolution, and optimal digitization.

  Further, in consideration of a necessary amount of information with respect to the imaging area and misidentification of the various dots 2, 3, and 4, it is desirable that the interval between the reference grid point dots 4 is about 0.5 mm vertically and horizontally. In consideration of misrecognition of the reference grid point dot 4 and the information dot 3, the shift of the key dot 2 is preferably about 20% of the grid interval.

  The distance between the information dot 3 and the virtual grid point surrounded by the four reference grid point dots 4 is preferably about 15 to 30% of the distance between the adjacent virtual grid points 5. This is because if the distance between the information dot 3 and the virtual lattice point 5 is closer than this distance, the dots are easily recognized as a large lump and become unsightly as the dot pattern 1. On the contrary, if the distance between the information dot 3 and the virtual grid point 5 is longer than this distance, it is difficult to identify which of the adjacent virtual grid points 5 is the information dot 3 having the vector directivity. Because it becomes.

For example, as shown in FIG. 4A, in the information dot 3, the lattice interval in which I ₁ to I ₁₆ are arranged clockwise from the block center is 0.5 mm, and 2 bits × 2 mm and 3 bits × 16 = 48. Represents a bit.

In addition, it is possible to further provide sub-blocks having independent information contents in the block and not affected by other information contents. FIG. 4B illustrates this, and sub-blocks [I ₁ , I ₂ , I ₃ , I ₄ ], [I ₅ , I ₆ , I ₇ , I, which are composed of four information dots 3. ₈ ], [I ₉ , I ₁₀ , I ₁₁ , I ₁₂ ], [I ₁₃ , I ₁₄ , I ₁₅ , I ₁₆ ] are independent data (3 bits × 4 = 12 bits) developed into information dot 3 It has come to be. By providing sub-blocks in this way, error checking can be easily performed on a sub-block basis.

  It is desirable that the vector direction (rotation direction) of the information dots 3 is uniformly determined every 30 to 90 degrees.

  FIG. 5 shows an example of the information dot 3 and the bit display of the data defined therein, and shows another form.

  In addition, using two types of information dots 3 that are long and short from the virtual lattice point 5 surrounded by the reference lattice point dot 4 and eight vector directions, 4 bits can be expressed. At this time, it is desirable that the longer one is about 25 to 30% of the distance between adjacent virtual lattice points 5, and the shorter one is about 15 to 20%. However, it is desirable that the center interval between the long and short information dots 3 is longer than the diameter of these dots.

The information dot 3 surrounded by the four reference lattice point dots 4 is preferably one dot in consideration of appearance. However, if it is desired to ignore the appearance and increase the amount of information, one bit is assigned to each vector, and the information dot 3 is expressed by a plurality of dots, so that a large amount of information can be provided. For example, the vector of concentric eight directions, an information dot 3 surrounded by four points lattice dots 4 can represent information of 2 ^8, and 16 pieces of information dots of one block 2 ^128.

  FIG. 6 is an example of information dot and bit display of data defined therein, where (a) shows two dots, (b) shows four dots, and (c) shows five dots arranged. It is shown.

  FIG. 7 shows a modification of the dot pattern, where (a) is a six information dot arrangement type, (b) is a nine information dot arrangement type, (c) is a 12 information dot arrangement type, and (d). Is a schematic diagram of a 36 information dot arrangement type.

  The dot pattern 1 shown in FIGS. 2 and 4 shows an example in which 16 (4 × 4) information dots 3 are arranged in one block. However, the information dots 3 are not limited to 16 pieces arranged in one block, and can be variously changed. For example, according to the amount of information required or the resolution of the camera, six information dots 3 (2 × 3) are arranged in one block (a), and nine information dots 3 in one block (3 × 3) Arranged (b), 12 (3 × 4) information dots 3 arranged in one block (c), or 36 (d) arranged 36 information dots 3 in one block.

  Next, the dot pattern used for the card in this embodiment will be described. FIGS. 8A and 8B show a specific lattice area (direction area) in the dot pattern of the block composed of 3 × 3 = 9 lattice areas in the dot pattern described in FIGS. Only by changing the arrangement direction of the information dots 3 from other lattice areas (direction areas), the direction of the block is defined.

  That is, in FIG. 8A, information dots 3 are arranged in the vertical and horizontal directions from the center in the lower left lattice region 34a, the central lattice region 34b, and the lower left lattice region 34c, and in the other lattice regions, the information is obliquely directed from the center. Dot 3 is arranged. By arranging the lattice areas 34a, 34b, and 34c in this way, it can be recognized that the block is upward from the shape of the triangle connecting the lattice areas, that is, the relationship of the vertex 34b with respect to the bases 34a and 34c.

  As described above, the direction of the block is defined by the arrangement relationship (here, a triangle) of the lattice areas 34a, 34b, and 34c in which the arrangement direction of the information dots 3 in the block is changed (information dots are arranged in the vertical and horizontal directions from the center). be able to. As a result, since the information dots 3 can be arranged in all the lattice areas in the block, the information dots 3 can be arranged in all the lattice areas without sacrificing the lattice area for the key dots. it can.

  Note that FIG. 8B is obtained by connecting two blocks shown in FIG. 8A in the vertical and horizontal directions.

  FIGS. 9A and 9B are diagrams showing the arrangement state of the information dots 3 corresponding to FIGS. 8A and 8B.

  10 to 11 are explanatory diagrams showing the relationship among the dot pattern, the code value, and the identifier.

As shown in FIG. 10, the dot pattern is a dot pattern composed of 3 × 3 block areas, and is divided into C _{1-0 to} C _17-16 within this block. FIG. 11 shows the dot code format of each area.

As shown in FIG. 11, C _{0 to} C ₅ mean character code, C _{6 to} C ₁₅ mean content / application code, and C _{16 to} C ₁₇ mean parity.

  When the dot pattern is printed on the back side of the card, it is desirable that the distance between the lattices is about 15 mm and the dot size is about 15% of the distance between the dots. Therefore, 2 mm to 2.5 mm is desirable, but not limited thereto. The resolution of the inter-dot distance at the time of imaging is desirably 14 pixels or more.

  In the present invention, a dot pattern is also used for a seal described later. FIG. 12 illustrates a dot pattern used for this seal.

  In FIG. 12A, values from 0 to 15 are expressed by the number of information dots and their arrangement. When there is no information dot, it means 0, and when there is one information dot, it means one of 1-4 depending on the arrangement. Further, in the case of two, 5 to 10, and in the case of 3, 11 to 14, and in the case of four, 15 respectively.

  In FIG. 12B, 4-bit values from 0000 to 1111 are represented. When the + y direction is the 1st place, the + x direction is the 2nd place, the -y direction is the 4th place, and the -x direction is the 8th place with respect to the virtual lattice point 5, and information dots are arranged respectively. 1 and 0 when no information dot is arranged. For example, when the information dot is not arranged at any position, it is 0000. Further, in the case of being arranged only in the + y direction and the + x direction, the 1st place and the 2nd place are 1, and the 4th place and the 8th place are 0.

  FIG. 13 is a diagram for explaining a card used in the present embodiment and another member attached to the card.

  The card according to the present invention is provided with a first dot pattern in which coordinate values or code values are patterned on the at least one surface by the above-described algorithm and can be recognized by predetermined irradiation light, and overlaps with an area where the first dot pattern is provided. A second dot pattern patterned by a predetermined algorithm is provided in a region or a different region. Both the first dot pattern and the second dot pattern may be printed on the card, and as will be described later, the first dot pattern is printed on the card, and the second dot pattern is attached and detached. It may be formed in another possible member. Alternatively, the first dot pattern and the second dot pattern may be printed on a card, and the third dot pattern may be formed on another detachable member.

  Further, it is desirable that the dots constituting these dot patterns are provided with a material that absorbs irradiation light such as infrared rays.

  As shown in FIG. 13A, the dot pattern described above is printed on the back surface (or front surface) of the card. In this dot pattern, a code value meaning a character is registered. FIG. 2B shows another member used in this embodiment. The separate member is formed as a seal. A dot pattern is printed on the surface of the seal. In the dot pattern, a code value as a parameter indicating power on the game is registered. For example, the type of technique and its strength, such as strong standing technique and strong sleeping technique, are registered as numerical code values. FIG. 4C is a diagram for explaining how to use the card and the seal. As shown in the figure, the sticker shown in FIG. The sensor unit inside the card game apparatus reads both the dot pattern of the card and the dot pattern of the sticker. Then, the character and power corresponding to the dot pattern are output, and the game is played.

  In the present invention, the dot used for the card and the dot used for the seal may be different in size. For example, as shown in FIG. 14, the dots used for the card can be large dots and the dots used for the seal can be small dots. Of course, the reverse is also possible.

  15-17 is a figure for demonstrating the sticker stuck on the lower part of a card | curd.

  FIG. 15 shows a seal formed in a planar shape. That is, the adhesive material is applied to the back surface (front surface) of the surface substrate on which the dot pattern is printed, and a silicone oil is applied to the surface to attach a backing that is easy to peel off. As the adhesive material, a material having a relatively weak adhesive force and capable of re-adhesion is used. As a result, the seal can be repeatedly attached to and detached from the card.

  FIG. 16 shows a seal that is used by being folded. This sticker is attached in a state that it can be folded along both sides of the card along the edge of the card. (A) is a bent state, and (b) shows a specific example of a dot pattern printed on a sticker. A mount is affixed to the back side of the seal, and a vertical cut is provided in the center of the mount. Thereby, it is comprised so that it may be easy to affix one side at a time. In this embodiment, as shown in (b), a dot pattern meaning 8 and a dot pattern meaning 1 are printed. When sticking a sticker so that the dot pattern meaning 8 is located on the back side of the card (the surface on which the dot pattern is printed) and when sticking so that the dot pattern meaning 1 is located on the back side of the card And the power of the character is different.

  Thereby, it is possible to output two kinds of parameters with one sticker, and it is possible to give the game flexibility.

  FIG. 17 shows a modified example of the seal used after being bent. This seal has a structure in which the seal is closed at the time of provision as shown in FIG.

  As shown in (c), an adhesive layer is formed on one surface of the seal, and the adhesive layer is divided into a strong adhesive region and a weak adhesive region with a folding line as a boundary. Before the card is mounted, one release sheet is interposed in each adhesive region in a folded state. As shown in (b), when the seal is peeled from the release sheet, the single-sided release of the release sheet is completed with the release sheet remaining only in the strong adhesion region of the seal. The weak adhesive region exposed in the single-sided peeled state is pasted on the front or back surface of the card. And after peeling the release sheet of a strong adhesion area | region, a seal | sticker is folded along the edge of a card | curd and a strong adhesion area | region is affixed on the back surface or surface of a card | curd.

  Thus, when the seal is folded, the seal can be provided with a smaller area. Therefore, it is possible to save the space of the vending machine. Further, by making the adhesive force in each adhesive region of the seal different, the user can surely peel off the seal in order on each side of the card.

  Moreover, you may make it set it as the structure which closed the seal | sticker at the time of provision by making the peeling force of a peeling sheet differ in front and back as follows.

  An adhesive layer having the same adhesive force is formed on one surface of the seal with the folding line as a boundary. Before the card is mounted, one release sheet is interposed in each adhesive region in a folded state. The release sheets have different peel forces on the front and back surfaces. When peeling the seal from the release sheet, the single-sided release of the release sheet is completed with the release sheet remaining only on the weak release force (strong adhesive) surface of the release sheet. The adhesive area exposed in this single-sided peeled state is affixed to the front or back surface of the card. Next, after the release sheet is peeled off from the remaining weak peel force surface, the seal is folded along the edge surface of the card, and the exposed adhesive region is attached to the back surface or the surface of the card.

  As shown in FIG. 17, a seal provided with a strong adhesion region and a weak adhesion region has a complicated manufacturing process. By making the adhesive strength of the seals the same and making the peel strength of the release sheets different between the front and back surfaces, it is possible to provide a seal that improves the convenience of sticking and peeling to the user with a simple manufacturing process.

  18-19 is a figure for demonstrating other embodiment of a seal | sticker.

  In the present embodiment, a plurality of seals each provided with a dot pattern are stacked. The layered seal has dots on each layer's seal so that the dot pattern imaged in the layered state and the dot pattern imaged with at least one of them peeled and removed have different values. A pattern is formed. The seal is made of a material that reflects the irradiation light for reading the dot pattern at the layer, and each of the seals constituting each layer is provided with a dot pattern having a different value by a material that absorbs the irradiation light. Yes. As a result, the dot pattern printed on the second and subsequent stickers cannot be recognized until the stickers are turned. Therefore, an independent dot pattern is printed for each sticker, and information dots printed on the sticker do not affect the dot patterns of other stickers. 18A is a view showing a state before the seal is turned, FIG. 18B is a view showing a state in which one seal is turned, and FIG. 18C is a view in which another seal is turned. It is the figure which showed the state.

  FIG. 19 is a perspective view showing a state in which the seals are overlapped.

  Thus, a different dot pattern appears each time the seal is turned. That is, when the seal is turned, the power of the character is different. Therefore, this sticker gives the user a sense of expectation as to what kind of power he will have when the sticker is turned over, and makes it possible to further show interest in the game.

  FIG. 20 is a diagram illustrating a vinyl case on which a dot pattern is printed. (A) is the figure shown about the external appearance of the vinyl case, and its usage, (b) is the figure which showed the state with which the card | curd was mounted | worn in the vinyl case. A dot pattern is printed on the vinyl case with invisible ink. On the other hand, no dot pattern is printed on the card. As shown in (b), the user plays the game with the card inserted into the vinyl case.

  According to this, since it becomes possible to change the parameter of a card | curd by changing to a vinyl case from which a dot pattern differs, a user can obtain various parameters with one card | curd.

  In addition, as shown in FIG. 21, the dot pattern may be printed on both surfaces of the vinyl case. By printing on both sides, it is possible to provide more parameters with a single vinyl sheet.

  In addition, although the present Example demonstrated the vinyl case which printed the dot pattern, this invention is not restricted to this, The transparent body in which the card | curd body, such as a plastic case, can be accommodated and the dot pattern was formed in the one surface or both surfaces Any other member may be used. Moreover, the 1st dot pattern may be printed on the card | curd, and the 2nd or 3rd dot pattern may be printed on the transparent body.

  FIG. 22 shows another member attached to the card as a clip capable of holding the edge of the card body. This clip is made of a thin resin. A dot pattern is printed on one side or both sides of the clip. Or the sticker which printed the dot pattern may be stuck on the one surface or both surfaces of a clip. The user attaches the clip to the card. Then, the game is played in that state.

  If the seal is a separate member, there is a problem that the adhesive strength of the seal is weakened if peeling and sticking are repeated many times. Further, depending on the adhesive material, the adhesive material may remain on the card, which may impair the beauty of the card. However, by using another member as a clip, the attachment force does not weaken even when the attachment and removal of the separate member are repeated, and thus it can be used repeatedly more freely.

  When the dot pattern of the clip is formed on the sticker, the sticker may be formed by laminating a plurality of stickers each provided with a dot pattern as shown in FIG.

  Next, an embodiment will be described in which the dot pattern is changed by peeling off or sticking a sticker on which a dot pattern is printed on a transparent material.

  The seal is made of a material that can transmit the irradiation light for reading the dot pattern, and is obtained from an image of the irradiation light that is transmitted through each layer when the dot pattern is imaged in a stacked state of at least two sheets. The dots are arranged in each layer so as to mean different values between the dot pattern and the dot pattern obtained from the captured image of the irradiated light when at least one of them is peeled and removed and transmitted through each layer.

  Alternatively, as described in FIGS. 23 to 24, when one or two or more seals are laminated and further pasted with a seal, the dot patterns may mean different values. .

  FIG. 23A shows an example in which the dot pattern is changed by increasing the number of dots. (1) shows the base seal, that is, the first seal. The base seal is made of an opaque material or a transparent material. (2) is a transparent seal. The transparent seal has a property of transmitting infrared rays. A reference grid dot and an information dot are printed on the base seal and the transparent seal, respectively. The reference grid dot and the information dot are printed with ink that absorbs infrared rays. (3) is the figure which showed the state which stuck the transparent seal | sticker on the base seal | sticker. By superimposing the seals, the value that the dot pattern means changes. Specifically, the value that the dot pattern means is 4 in (1), 2 in (2), but 9 in (3).

  In addition, when printing a dot with invisible ink, it is necessary to print the marker for affixing position on a base seal and a transparent seal. When printing dots with visible ink, the user puts both reference grid point dots and attaches a transparent seal. Further, the reference grid dot may be printed with visible ink, and the information dot may be printed with invisible ink.

  FIG. 23B is an example in which the dot pattern is changed by reducing the number of dots. In this embodiment, in order to prevent imaging of dots arranged in the lower layer when any one of the layers is irradiated with irradiation light, a mask portion provided with a material that reflects the irradiation light on the layer. (Mask dot).

  (1) is a base seal, (2) is a transparent seal, and (3) is a view showing a state where a transparent seal is stuck on the base seal. The transparent seal is printed with dots (mask dots) printed with infrared blocking (reflective) ink. When the mask dot is arranged on the dot printed with the infrared absorbing ink, the dot printed with the infrared absorbing ink is hidden and is not picked up by the image pickup means. Therefore, since only the dots printed with the infrared absorbing ink are imaged, the recognized dot pattern changes. Specifically, in (1), the value that the dot pattern means is 5. In (2), mask dots are printed in the + x direction. In (3), since dots printed with infrared absorbing ink are hidden in the + x direction, the information dots to be imaged are only dots in the + y direction, and the value that the dot pattern means is 1.

  FIG. 23 (c) is an example in which the example of (a) and the example of (b) are combined. That is, the dot pattern is changed by both increasing and decreasing the number of dots. As shown in (1), the meaning value of the information dot of the base seal is 5. In (2), dots are printed with infrared absorbing ink in the -y direction, and mask dots are printed with infrared blocking (reflective) ink in the + x direction. When the transparent sticker (2) is pasted on the base sticker (1), the dots in the + y direction and the −y direction are imaged, and the value that the dot pattern means is 6.

  FIG. 24 is a perspective view showing a state in which the seals are overlapped in the examples of FIGS.

  According to this, each time the seal is peeled off or applied, a different dot pattern appears. That is, when the seal is peeled off or pasted, the power of the character changes. Therefore, this sticker gives the user a sense of expectation of what kind of power it will have when the sticker is peeled off or pasted, and makes it possible to make the game more interesting.

  FIG. 25 is a view showing another embodiment of the card according to the present invention. In this embodiment, a notch for positioning at the time of attaching a seal is provided at the edge of the card. This card is mainly used when the seal shown in FIGS. 16 and 17 is used. By providing such a notch, it is possible to prevent the sticker from being shifted and stuck when the folded sticker is attached to the card, and to stick the sticker at an appropriate position.

  There may be only one notch as shown in FIG. 25 (a), or two may be provided as shown in FIG. 25 (b). When the sticker shown in FIG. 5 is affixed to a card having two notches, the dot pattern combinations of the two stickers are 256 × 256 = 65536.
