Description

  The present invention relates to a code-type card system, for example, a code-type card system suitable for play and education, and more particularly to a card toy.

  As a card-type toy, an information display unit consisting of colors and numbers is placed near one side of the surface of multiple cards, a question is drawn on the remaining parts, and these cards are distributed to two players. There is a case in which the two players share each other and decide to win or lose by the magnitude of the card number, and the losing person has an obligation to answer the question text of the winning card (Patent Document 1).

  Also, a bar code for recording numerical data is displayed on the game card, and by using this numerical data, the card used by the attacking player and the card used by the defense player are played against each other. A card system that competes for superiority and inferiority is also known (Patent Document 2).

In addition, it is a collection card that depicts the characters of characters such as people and monsters on the surface of the card, and a data storage unit corresponding to the character is formed on a part of the card, and a pattern display unit is formed on the remaining part. There is also known a card system configured to read the data with a game device with a reading means and make a voice corresponding to the character or generate a mini game (Patent Document 3).
JP2003-205061 No. 5-30475 JP 2002-336399 A JP 08-299602 A JP-A-11-227367 "Knowledge of barcodes and two-dimensional codes to know" P3 Junya Hiramoto, Nihon Kogyo Publishing, published on November 10, 1991

  Since the card systems of Patent Document 2 and Patent Document 3 play using specific information recorded on a card for a specific pattern drawn on one card, only information corresponding to the number of cards is available. It was not available and was poorly changed.

  On the other hand, although it does not use a code, it consists of a first sheet-like object depicting a person and a plurality of second sheet-like objects having the design and shape of the person's costume, and the second sheet-like object A dress-up toy in which an object is detachably formed on a first sheet-like object is also known (Patent Document 4).

  A first object of the present invention is a state in which at least a specific part of a plurality of cards has a code display area formed of a light-transmitting material, a partial code is described in the area of each card, and the cards are overlapped It is possible to read an entire code obtained by synthesizing partial cards, and to provide a code type card system capable of expanding a variety of information by combining the cards.

  A second object of the present invention is to provide a code-type card system capable of matching pictures by adopting the above-described dressing play technique by making the design display area of each card transparent.

  A third object of the present invention is to provide a code-type card system provided with means for aligning cards in order to accurately perform such code alignment or picture alignment.

  A fourth object of the present invention is to provide a card system having a code system having a large tolerance with respect to a reading error due to misalignment between cards.

In a code-type card system including a plurality of cards, a corresponding portion of each card is a code display area in which information is coded, and a remaining card portion is a design display area.
At least the code display area 6 of each card is allowed to transmit light, and the partial code 12 displayed in this area is synthesized as a whole code 14 within the visual field in the overlapping direction when a set of cards are stacked at the normal position. Each of the partial codes 12 is arranged.

  In this means, code information (entire code) that has been recorded on a single card in the past can be distributed and stored in a plurality of cards, and the partial information (partial code) of each card can be synthesized by overlapping the cards. I am doing so. It is desirable that these partial codes constitute certain information used for play regardless of which card is combined. In order to be able to synthesize the partial code with the cards superimposed, at least the code display area is formed of a light transmitting material. The phrase “transparent” rather than “transparent” means not only transmitting visible light but also transmitting non-visible light. For example, although it is not a transmissive card | curd, storing code | cord | chord information in a card | curd using infrared rays absorption ink is conventionally well-known (patent document 5).

  The “code type card system” includes a plurality of cards. “Plural” means a set of cards that constitute a code-type card system. Normally, a plurality of types of cards corresponding to the required number of parts for picture matching are included, and one or two or more of the same type of cards are included for each type. On the other hand, the term “a set of cards” refers to a set of cards selected for a single card play operation (for example, an operation for creating a single design) from a set of cards. The code-type card system may include a card holder described later in addition to the card itself, and may be a game system that wraps a game device with card reading means.

  The “card” includes a design display area and a code display area suitable for playing games. It can be used for a variety of card games, such as a type to enjoy picture matching such as dress-up games, and a battle type that competes for superiority or inferiority of the score recorded as code information. Such cards generally have the same shape, but it is sufficient that at least each card has a shape or a structure that can be superimposed on a correct position where code information can be read. In addition, it is desirable to provide such alignment means in a part of the card. For example, it is possible to form alignment marks (dots or patterns) on the transparent portion of the card or to make alignment holes, but each side or each corner of the card as described later. It is recommended to align the positions so that the positions match.

  In this specification, “alignment” refers to the positional relationship in accordance with the intention of the manufacturer when the display items in the card design display area and code display area are observed from the stacking direction with the cards stacked. It means to make. In addition, such a relationship means that the card is in the “normal position”.

  The “design display area” has a function of representing a picture / character / symbol for playing. This area is provided so that the colored portion of the picture transmits visible light when performing picture matching play. However, it is not always necessary to do so. For example, in the case of using only for collecting points recorded as code information on collected cards, light may not be transmitted.

  The “code display area” is a part for displaying code information, and when the cards are the same shape, it corresponds to the same place and when the cards are not completely the same shape so that the information can be synthesized by superimposing the cards. It is good to form in place. The code display area is formed in a solid area except for the code. This is because if there is a pattern other than the code, a reading error occurs.

  The “partial code” means a part of the information of the entire code and constituting the entire code by synthesizing each partial code. Here, “synthesizing” means synthesizing with information of other partial codes without damaging the information held by the partial codes. For example, for dress-up games, cards representing people, clothes, hats, belongings, etc. are prepared. For the battle type, cards representing people, combat clothes, weapons, etc. are prepared. It can be stored as information, and when the cards are overlapped, the points represented by each part of the entire code can be summed up to compete for points. A game or other actions may be generated in the game device by synthesizing all or some of the partial codes of the set of cards and causing the game device as in Patent Document 3 to read them.

  “Code” refers to information that represents information by a set of dots and lines in this specification, and includes so-called bar codes and two-dimensional codes. However, in the present invention, the partial codes of the cards are synthesized and read, so that some degree of misalignment between the cards tends to occur. In the present invention, a code system with a small reading error due to the deviation is proposed. As a method for reading the code, either a transmission type in which light is irradiated to measure transmitted light or a reflection type in which reflected light is measured may be used.

The second means has the first means, and the card 4 is formed of a transparent material, and a new design can be synthesized by overlapping or continuing the parts 10 of the design display area 8 of each card. It is configured as follows.

  In this means, a code-type card system is proposed in which the cards are transparent, the designs are superimposed, and the pictures can be matched. It is preferable to record code information corresponding to the contents of the design.

The third means includes the second means, and each card 4 is a rectangular card having substantially the same shape and the same size, and by aligning at least two sides of the cards, each card 4 overlaps with the normal position. ing.

  This means proposes one of preferable positioning means. Keeping the cards in the same size and aligning and stacking the cards is natural in card play, and it is important that the partial codes of each card are correctly superimposed in the normal operation. . This is because the player can concentrate on the play.

  The 4th means has the 3rd means, and draws the part 10 of the design according to the partial code 12 in the design display area 8 of each card | curd 4, and is normal by overlapping a set of cards in a normal position. New designs are synthesized, and when these cards are stacked out of the normal position, the synthesized designs are in an abnormal state.

  This means is means for adjusting the position of the card together with the picture matching operation to prevent the right / left / up / down inversion. For example, when you synthesize the design of a person wearing costumes, hats, and shoes by overlaying design parts such as people, costumes, hats, and shoes as shown in Figure 2, for example, if you stack one card upside down, When the hat is placed upside down on the side of the person's head as shown in FIG. 3, the hat is shifted toward the foot of the object as shown in FIG. It will be unnatural to the child's eyes and will try to replace the card correctly. This picture matching operation also serves to align each partial code. A condition for adopting this alignment method is that each part is uncontrastable in the horizontal direction or vertical direction of the card. This will be described later.

The fifth means includes any one of the first means to the fourth means, and extends the code display area 6 along one side of each card having the same shape and the same size as a rectangle,
In each code display area 6, at least two or more bars 16 encoded with information thickness are arranged perpendicularly to the side direction, and the partial codes 12 of each card 4 are arranged at intervals. Is forming.

  This means proposes a method in which a series of barcodes are synthesized by providing each bar, which is a so-called bar code component, distributed on each card and overlapping the cards.

  In general, a “bar code” generally refers to “information encoded by an array of parallel and rectangular bars or spaces of varying width” (Non-Patent Document 1). Since the cards tend to be misaligned in the direction (perpendicular to the bar), the information coded by the distance between the bars has a large error. Therefore, information is coded only by thickness.

  In general barcodes, in addition to the start character, data character, and stop character, a blank space (quiet zone) is placed before the start character and after the stop character to distinguish the series of characters from the other elements of the product. It arranges (nonpatent literature 1). In the case of the present invention, the chord zone is replaced with a quiet zone by making the code display area plain. The stop character can be omitted. In the preferred embodiment described later, the start character is formed at the same position on all the bars, the data character having information is divided as a partial code corresponding to each design, and is distributed to the corresponding position on each card. .

  One of the important things in this means is that when distributing each part of the bar code to a plurality of cards, the two or more bars adjacent to each other in the original code are distributed to each card as one block. . This is because reading errors due to card misalignment can be reduced.

The sixth means is the code type card system of the fifth means,
Instead of the bar 16 of the fifth means, a linear code element 18 configured as a line segment or a combination of line segments or dots connected in the line direction is arranged with a gap between each code area. ,
Each linear code element is formed so as to represent information by the length of the line segment and the arrangement of dots.

  This means is similar to a so-called bar code, but proposes a code system more suitable for the use of the present invention than a bar code. As described above, in the present invention, there is a possibility that the cards are shifted in the side direction, so a method for storing information as a line segment or a combination of line segments or dots in the length direction of the line segment perpendicular to the side is proposed. Yes. The use of the term “linear code element” with respect to the “bar” in the previous means means that it also includes, for example, a dot-sequence of dots. In the case of a bar code, the information is represented by the thickness of the bar or the gap between the bars, and all the bars are the same in the longitudinal direction (that is, they have no information), whereas the linear code of this means is used. The element encodes information by the dot appearing in the longitudinal direction, the arrangement of the line segment, the length of the line segment, and the like. “Linear” means that information is arranged in the line direction, and actually includes a certain width similar to “bar”.

The seventh means includes sixth means, and the linear code element 18 has a reference length or an equal multiple of the reference length when the entire code 14 is synthesized by overlapping the cards in the normal position. Are regularly arranged,
Each linear code element 18 is configured by a reference unit 20 indicating the timing of reading information, or by the reference unit and a data unit 22 indicating information, and the reference unit is equidistant from one side of the card 4. positioned.

  This means proposes a code system suitable for reading information obtained by running the code display area on one side of the card with respect to the card reading means. In the above configuration, the “reference unit” corresponds to the reference clock of the digital circuit. It is common practice to use a reference clock to synchronize devices. In the case of the present invention, a reference portion corresponding to a reference clock is printed on the card itself, and each reference portion and a data portion representing information are combined to notify the machine of timing for reading the data. .

The invention according to the first means has the following effects.
○ Because the information of the entire code is distributed as a partial code on multiple cards, for example, in a competitive game where you compete for the superiority or inferiority of points with your opponent, compared to conventional card games where you can only set points for the number of cards By combining a plurality of cards, a very large number of points can be set.
○ By making the card 4 light transmissive, the partial codes of each card are superimposed and combined, so the combining method is simple and the entire code 14 can be read easily.

  According to the second aspect of the invention, since the card is made transparent, it can be applied to various game methods such as changing clothes and playing games.

  According to the third aspect of the invention, it is possible to align the cards only by aligning the cards, and the code information can be read accurately, which is convenient.

  According to the fourth aspect of the invention, when at least one of the set of cards is replaced from the correct position, the synthesized design is in an abnormal state. It is convenient because the position of the partial code is aligned correctly by the act of trying to complete the design correctly.

The invention according to the fifth means has the following effects.
Since the code display area 6 is taken along each side of the rectangular card 4 and the partial code 12 orthogonal to the side direction is formed, the code information can be easily read by the card reader.
○ At least two or more partial codes 12 are displayed in a row for each card, and there is no possibility of misalignment between the partial codes on the same card. Can be reduced.

  According to the invention relating to the sixth means, the partial code 12 in the configuration of the fifth means is replaced with the linear code element 18, so that the effect of the invention of the fifth means is achieved and each linear element is Since information can be stored as the length of a line segment or the position of a dot in the longitudinal direction, there is an effect that it is hardly affected by a shift in the side direction of the card.

The invention according to the seventh means has the following effects.
The linear code elements 18 are regularly arranged with a reference length or an equal interval when the entire code 14 is synthesized by overlapping each card in the normal position. Even if there is an error, the code information can be read accurately.
Each linear code element 18 is constituted by a reference portion 20 indicating the timing of reading information, or a reference portion and a data portion 22 indicating information, and the reference portion is equidistant from one side of the card 4. Therefore, when the code information is read by the card reader, more accurate reading can be performed using this reference portion.

  1 to 9 are used in the corded card system according to the first embodiment of the present invention.

  The corded card system 2 is composed of a plurality of cards 4. These cards are formed in the same shape and size so that the sides are aligned when superimposed. FIG. 1 shows a state in which the cards are superimposed, and FIG. 2 shows each card individually. The illustrated card is rectangular, but its shape can be changed as appropriate.

  A part of each card 4 is formed in the code display area 6 and the remaining part is formed in the design display area 8. Each area is formed with the same size and shape at the same place on all cards. In the illustrated example, the code display area is formed in a strip shape along the long side of the card, but may be provided on the short side of the card. Each card 4 is formed of a transparent material so that the display objects in the display areas 6 and 8 appear to overlap each other when superimposed. Specifically, it can be formed of PP material, PVC material, PET material, and styrene resin.

  As shown in the lower part of FIG. 2, design parts 10 such as a person, a hat, clothes, and shoes are drawn in the design display area 8 of each card 4. These parts are combined by superimposing cards as shown in the upper part of Fig. 2, resulting in a design that is a human figure wearing a hat, costume, and shoes. In the example shown in the figure, a set of code-type card systems is configured with four types of cards of persons, hats, clothes, and shoes, and there are one or more different parts of cards for each type of card.

    A partial code 12 is displayed in the code display area of each card. The code desirably includes information corresponding to the design display area of the card. Of course, merchandise management information or other useful information may be recorded together with such information or instead of the information. When a plurality of cards are stacked, the partial codes 12 of these cards are combined to form an overall code 14. The code format will be described later.

  These partial codes are misaligned and cause a reading error when the cards are overlapped incompletely. In the present invention, the card is positioned by the following means.

    First, misalignment in the direction of each side of the card is prevented by aligning the side adjacent to that side. For example, when the codes are arranged in the long side direction as in the illustrated example, the short sides of the cards may be aligned. It is possible for even younger children to align the sides with a small error range (for example, less than 1 mm) by putting the end face of each short side of the card against the top surface of the deck of the desk. Therefore, in a code composed of a bar and a linear code element, which will be described later, a gap such as a bar may be set larger than an expected error range.

Secondly, a case where a card is inserted in the left-right direction and the up-down direction will be described. As already described with reference to FIGS. 3 and 4, it is possible to determine whether or not alignment is appropriate in a state where the parts 10 in the design display area are combined. The condition for enabling this alignment is that the parts 10 in the design display area of each card are not contrasted in the horizontal direction of the card with respect to the horizontal alignment. For example, in the illustrated example, since the form code display area 6 on the left side of the card, left and right center line L ₂ of the design display area 8 is shifted to the right than the left and right center line L ₁ of the card. Thus it may draw each part 10 about the lateral center line L ₂ of the design display area. Further, the appearance of the person may be left and right uncontrasted, and the positions of clothes and shoes may be made to correspond thereto. Also, regarding the vertical alignment, each part is uncontrastable. Parts for dress-up games such as people, clothes, and shoes are not very vertically symmetrical, and no special device is required for such objects.

  Next, the code format of the present invention will be described with reference to FIGS. First, FIG. 7 shows a bar code system using a general bar 16, and FIGS. 5 and 6 show a code system using the linear code element 18 of the present invention. The bar 16 encodes information that a thin bar is 0 and a thick bar is 1. The linear code element 18 represents information by the length in the line direction. The bar 16 and the linear code element are binary types. In the case of a bar, the thin bar is 0, the thick bar is 1, and the linear code element is 0 for the short and 1 for the long. The information is coded in The bar or linear code element drawn at the bottom of the code display area of each figure is a start character that represents the beginning of a series of codes, and is provided on all cards. The first reason for this is that if a start character is provided only on a specific card, information cannot be read in a combination of cards that do not include the specific card, and the degree of freedom of the combination is impaired. is there. The second reason is that the code can be read by each card alone as will be described later. Above that, data obtained by encoding data relating to each card is displayed. In the example of FIG. 5, three types of cards (1) to (3) are used. Excluding the above start character, the card (1) has four (4 bits) linear code elements 18 at the bottom of the code display area 6, and the card (2) has eight lines at the middle of the code display area 6. In the card (3), four linear code elements are displayed in the upper part of the code display area 6 respectively. Thus, the linear code elements of the same card are adjacent to each other, and the distance between these elements is unchanged. The lower part of FIG. 5 shows the state of the synthesized overall code when two or three of the three types of cards are overlapped. Here, the interval between the linear code elements is constant.

In the above configuration, a specific example of playing using this code type card system will be described.
[Embodiment 1] When there are relatively few types of cards as shown in FIG. 5, one of the three types of cards is used alone, any two are combined, or all three are combined. Different actions can be generated by causing the card data reading means of the apparatus to read the data. For example, the present invention can be applied to a conventionally known Janken-type battle-type card game. 6 and 7 use six types of cards, and only when all types of cards are stacked, a significant overall code is synthesized and a predetermined action is generated by the game device. 6 and 7 differ only in the type of code.
[Embodiment 2] Further, in a battle-type play (so-called card battle), strength and win / loss can be determined by a combination of weapons and cards of protective means. Its strength is not just uniform, but by coding a complex strength rule such as Janken stones, scissors, paper and other items that are strong but weak to other items, a battle that flew into change It becomes possible.
[Embodiment 3] In the dress-up game, the code changes depending on the difference in clothes, hats, accessories, etc., so it is possible to determine the fashion level. The fashionability is not the sum of the fashionability of each simple item, but this clothes and hat look good, but you can respond to more complex play by evaluating that it does not fit another hat. In addition, it is good to memorize | store the strength of the weapon of Example 2, the relationship of the fashionability of the item of Example 3, etc. in the below-mentioned game machine.
[Embodiment 4] A correct answer sound is generated when the codes are correct combinations, and an incorrect buzzer sound is generated in an after-mentioned game device when the codes are not correct combinations, which can be used for children's education.
[Embodiment 5] Each partial code can have a design that is pleasant to the child's eyes by making the front surface various colors and making the back surface difficult to transmit light.

  FIG. 8 is an explanatory diagram of the linear code element of the present application. In the illustrated example, two types of long and short linear code elements are used in the upper half of the figure, and the lower half of the long element is the reference portion 20 and the upper half is the data portion 22. In the lower half of the figure, these upper and lower halves are drawn separately for explanation. The reference unit 20 is arranged so that the machine can read the card when the card runs along the same virtual line in the line direction. This reference portion is for informing the card data reading means of the timing for reading data in the data portion. The data part 22 represents data. In the case of the illustrated example, a long linear code element has a data part, so “1” is indicated, and a short linear code element does not have a data part, so “0” may be indicated. . This is of the binary type, but it can also be of the multi-value type in which the length of the data part changes as 0, 1, 2,. Further, the reference portion and the data portion do not need to be continuous, and may be separated as shown in the lower part of FIG. Further, since each linear code in the illustrated example has a constant width (thickness), the margin for deviation when the cards are stacked is large, and thus the reading accuracy is high. Further, since the reference portion has the number of all bits, it is easy to check the reading error. Furthermore, it is resistant to fluctuations in the feeding speed when cards are sent manually.

  FIG. 9 is a modification of the example shown in FIG. 1, and uses a two-dimensional code in the code display area. As in FIG. 1, a strip-like code display area is formed on the long side of the card, and a two-dimensional code corresponding to the number of design parts is arranged in the longitudinal direction of the strip. However, the position of each two-dimensional code can be changed as appropriate. In the drawing, the fine shape of the two-dimensional code is omitted.

  FIG. 10 shows a corded card system according to the second embodiment of the present invention. The code type card system includes a set of cards according to the first embodiment, a card holder 24, and a card data reading means 30.

    The card holder 24 accommodates the card therein and reads the data together with the holder through card data reading means. Therefore, the card holder is formed of a light transmitting material (preferably a transparent material). The card holder has a rectangular shape, and has a card insertion slot 26 formed on one surface thereof, and a lid for closing the card insertion slot. In the illustrated example, the card holder is drawn slightly larger than the card for convenience of drawing, but in order to prevent misalignment between the cards, the inner surface of the card holder is fitted to fit the vertical and horizontal widths of the card. It is desirable to design the corresponding dimensions.

  The card data reading means 30 is configured to read data by inserting an opening 32. As shown in FIG. 11, the principle of the card data reading means is that a light shielding plate 34 with slits 36 is arranged on both sides of a card traveling path, and a light emitting section 38 such as an LED and a light are provided on both sides of the light shielding plate. A light receiving unit 40 as a sensor is installed. The light emitted from the light emitting section 38 enters the light receiving section 40 through the first slit 36, the card code display area 6, and the second slit 36, thereby reading data.

  The slit is provided narrower than the width of the bar or linear code element constituting the cord. Further, the LED and the optical sensor use either a visible light type or an infrared light type depending on the code printing conditions.

    The illustrated light receiving section includes a first light receiving body 40a and a second light receiving body 40b. When the optical path from the light emitting section to the first light receiving body 40a is blocked by the reference section 20, the second light receiving body. The light received by 40b is sent as data to a control unit (main circuit) (not shown). As a result, accurate reading is possible without being affected by dirt on the card. The entire apparatus shown in the figure can be a game machine for card games, and the card data reading means can be a part of the apparatus. In that case, the game device may include a control unit and a storage unit, and store the play rules described in the first to third embodiments.

    In addition to the transmissive code reading means in the illustrated example, a conventionally known reflective type may be used. In this case, the light emitting unit and the light receiving unit are grounded on one side of the card, and the presence or absence of light reflection is read. However, the number of transparent cards that can be read is considered to be smaller than that of the transparent type. Furthermore, a conventionally known image sensor method may be adopted. In this method, a plurality of light emitting elements and light receiving elements are arranged in a line and all bits of the code are read at once.
