EXAMPLES The present invention will now be described in more detail with reference to examples. Needless to say, the scope of the present invention is not limited to such examples. Here, a battle-type card game is exemplified. First, a card having a layer structure shown in FIG. 2 is prepared as a card used in a card game. The card substrate was a sheet of polyethylene terephthalate (PET), a color tone change type was used as the reversible recording layer, and an ultraviolet curable resin was used as the protective layer.

As shown in FIG. 3, the reversible display portion 47 on the surface of the card has visible information on the attack power, defense power, and experience value of the character, as well as weapons, armor, and other items currently owned by the character. Visible information such as special weapons and armor is displayed. As shown in FIG. 4, a pattern of a character is printed on the print layer 41 on the back surface of the card. A reversible display unit may be provided on the back surface, and the character design may be reversibly displayed. Alternatively, a part of the design may be printed and the remaining part may be displayed reversibly.

Information that is not displayed on the reversible display area includes terrain effects (advantages and disadvantages of randomly set battle places for each character), compatibility (pros and cons for each character), and good luck (randomly). Other necessary information items are set according to the set value), the game system, the operating method, the progress status, etc., and these invisible information are recorded in the information recording unit.

The method of using the card game system will be described below with reference to FIGS. 5 and 6. 5 and 6
3 is a flowchart showing a method of using the card game system of the present invention. First, the card game system is turned on to start the card game. In step S1, cards are set in the card transport section of the card game system and n cards are inserted into predetermined positions of the card game system. Here, each of the n cards is specified by a character. In step S2, the count is set to X = 1, and in step S3, the information recorded in the information recording unit such as the magnetic recording layer of the Xth card is read via the data reading unit,
Store in RAM. In step S4, count X
If is smaller than n, 1 is added to the count X in step S5, and then step S3 is repeated. In step S4, it is confirmed whether the count X has reached n,
When the count X is n or more, information recording of all X cards (information recording of X characters) is completed, so next, in step S6, there is communication data of the card desired to participate in the game. If there is no communication data, the process proceeds to step S12. If there is communication data, all communication data (m pieces of communication data) are received via the communication interface in step S7. Here, the communication data of the m cards is specified by the character. By using the communication interface in this manner, it is possible to compete with an opponent located at a geographically distant place and enjoy the game together. Next, in step S8, the count is set to Y = 1, and in step S9, the information of the Yth communication data is stored. Step S10
If the count Y is smaller than m in step S11, 1 is added to the count Y in step S11, and then steps S9 and S10 are repeated. In step S10, it is confirmed whether or not the count Y has reached m. If the count Y is m or more, the reading of m communication data (information of m characters) is completed, and thus the battle is started. It should be noted that here, although the configuration is such that n cards are inserted into the card game system,
It is also possible to adopt a configuration in which after reading the information by inserting the cards one by one and inserting the nth card, that is, when the card to be inserted is exhausted, an instruction for no card is sent to proceed to the next step.

At the start of battle, first, step S12.
The count Z is set to 0 at. In step S13, n cards (n characters) and m communication data (m characters) are distributed to either the attacking side or the defending side, and the attacking character members and the defending character Determine members. In step S14, the total offensive power is obtained in consideration of the attack value of the offensive character, such as experience value, terrain effect, and compatibility with the opponent character. In addition, step S15
In the defense power of the defending character, the total defense power is calculated in consideration of experience value, terrain effect, compatibility with the opponent character, and the like. In the calculation of the total attack power and the total defense power, the fortune may be randomly determined using a random number table or the like, and the fortune may be added. As described above, in calculating the total attack power and the total defense power, the compatibility and holding ability of each character greatly influences the development of the game. Therefore, selection of the character becomes important, and a heated battle can be expected.

In step S16, the total attack power and the total defense power are compared, and if the total attack power is greater than the total defense power, that is, if the numerical value is large, the attacking side wins, and the attack in step S17. The difference is given to the side as a point and stored. If the total attack power is less than or equal to the total defense power, the attack has failed,
No points are given to the attacking side, and the process proceeds to step S18. It should be noted that, although the calculation configuration for giving the negative points to the loser side is not made here, it is also possible to have a configuration for giving the negative points to the loser side. Step S
At 18, it is confirmed whether or not the count Z is 1, and if Z is not 1, that is, if Z is zero, step S1.
At 9 the attack and defense are changed, and the defending team starts the attack. First, after adding 1 to the count Z in step S20, steps S14 to S18 are repeated. In step S18, it is confirmed whether or not the count Z is 1, and when the count Z is 1, the attack ends one by one and the battle ends.
At, the "battle result" is displayed on a display device such as a liquid crystal display. Here, the team with the most points will be the winner.

Information is updated for each character of the winning team and each character of the losing team according to the battle result. The character who wins has increased attack power and defense power according to the battle result. The losing character has a reduced attack power and defense power, but at the same time, the experience value increases, and the character is carried over to the next match. That is, the battle result is calculated for each character in step S32, the count X is set to 1 in step S33, and the information recorded in the information recording medium of the Xth card is calculated in step S34. Based on the updated information displayed on the reversible display unit of the Xth card in step S35, the rewriting is performed using the rewrite rewriting unit. Next, in step S36, it is confirmed whether or not the count X has reached n. If X is smaller than n, 1 is added to the count X in step S37, and then steps S34 to S36 are repeated, and all cards are processed. Update the invisible information record and rewrite the visible information display. In step S38, it is confirmed whether or not the game has participated in the game based on the communication data.
Move to and eject the card. When the game participates in the game using the communication data, the count Y is set to 1 in step S39, and the update information is sent to the Yth communication data in step S40. Next, step S41
In step S43, it is confirmed whether or not the count Y has reached m. If the count Y is smaller than m, 1 is added to the count Y in step S43, and then steps S40 to S41 are repeated. When the count Y becomes m or more in step S41, the correction data transmission to all the characters participating in the game is completed by communication, so the card is ejected from the card game system in step S42, and the game is executed. finish. Note that cards that have participated in the game via the communication interface may be set to be ejected from the card game system after the game is over. In addition, the calculation conditions and calculation settings applied to the card game system are
It can be appropriately set according to the design of the card game system.

Although the information recorded in the information recording portion such as the magnetic recording layer of the card for the card game system is updated, two or more different characters are recorded so that each character can be updated. May be. The card for which the battle has ended and the character information has been updated is
It is a card that has different information from before the battle, and if visible information is displayed on the reversible display section by the rewrite rewriting section,
You will be satisfied with the numerical information and textual information, and will be excited to fight for the next game. Further, in the case of a card game in which the character grows, it is possible to enjoy the growth stage of the character displayed on the reversible display unit. In a card in which a plurality of characters can be stored, a plurality of characters can be displayed on the reversible display unit as needed, so that the need for a card collection can be satisfied.

In the embodiment, the battle-type card game has been described, but other than this, the present invention can be applied to a game in which images change such as a role-playing game and a breeding game.
