FIG. 5 is a flowchart for explaining the flow of the entire game.
This flowchart is a flow from a state where a game is started and a screen for organizing a party is displayed on the liquid crystal monitor 28.
(1) The process starts by selecting a character to be used in this battle game and organizing a party (step (hereinafter referred to as “S”) 001).
The player places three of the character cards on hand on the scanner (card placement unit 36), and the placed RFID reader / color electronic paper writer reader recognizes the character card (the player has four areas). You can place it in any area).
-When the player places a character card and presses the enter button or times out after a certain time, the game machine ends the party organization.
・ If there are more than 3 cards at the end of the party organization, the game machine will automatically select 3 cards at random.
・ When the number of cards is less than 3 at the end of the party organization, the game machine adds a shortage of CPU cards (CPU cards fight automatically).
・ From now on, game machines will treat these cards as invalid cards.
When the party organization is completed, the game machine downloads data corresponding to the ID of each character card stored in the server device.

表１はメインテーブルの例を、表２はキャラクタタイプ別特性テーブルの例を、表３は武器タイプ別特性テーブルの例を、表４は防具タイプ別特性テーブルの例を、表５にアイテムタイプ別特性テーブルの例をそれぞれ示す。
上記各表に示す内容の各キャラクタのデータがダウンロードされ、その能力を示すデータを用いて各キャラクタはバトルを行うこととなる。 Tables 1 to 5 show data on the server.

Table 1 shows an example of a main table, Table 2 shows an example of a characteristic table by character type, Table 3 shows an example of a characteristic table by weapon type, Table 4 shows an example of a characteristic table by armor type, and Table 5 shows item types. The example of another characteristic table is shown, respectively.
The data of each character having the contents shown in the above tables is downloaded, and each character performs a battle using the data indicating the ability.

(2) When the data preparation is completed, the game machine starts a battle (S002).
The battle system is as follows.
A direct attack possible range and a magic attack possible range are set for the character, and an attack is performed by capturing an enemy character in these ranges.
FIG. 6 shows an example of the game screen of the liquid crystal monitor 28 and shows an example of a battle method.
In the normal attack state, a possible attack range is displayed around the player character 70 with a red ring 60. When the enemy character 61 is captured within the directly attackable range 60a, the ring 60 is filled and attacked with a weapon.
In the Magical Attack state, the magic attack possible range is displayed around the player character 71 with a purple ring 62.
When the enemy character 72 is captured within the magic attack possible range 62a, the ring is filled and attacks with magic.
Rings are not displayed in Guard and Magical Heal states.

The operation by the player is performed as follows.
Each character is operated by reading a character card corresponding to each character with a card reader provided in a card placement unit on which the character card is placed. As described above, the area where the character card is placed is divided into four areas, Normal Attack, Magical Attack, Guard and Magical Heal, and each area corresponds to the following operations.
1) When a card is placed in the Normal Attack area • The corresponding character enters the Normal Attack state and moves (towards the nearest enemy) to capture the enemy character directly within the attackable range. At this time, the attack range of the enemy character moves without concern.
・ If the enemy character is captured within the attackable range, it will attack directly.
・ When attacked by enemy characters, the damage is large.
The character card placed in this area has a red 65 on the liquid crystal display as shown in FIG.

2) When a card is placed in the Magical Attack area • The corresponding character enters the Magical Attack state and moves to capture the enemy character within the possible magic attack range (towards the nearest enemy). However, the enemy character tries to escape from the direct attack range.
・ When the enemy character is captured within the possible range of magic attack, it will magically attack.
・ When attacked by enemy characters, the damage is large.
-Consume 1 MP per second. When MP is lost, it becomes Normal Attack state.
The character card placed in this area has a yellow 66 on the liquid crystal display as shown in FIG.
3) When a card is placed in the Guard area • The corresponding character enters the Guard state and moves to escape from the attack range of the enemy character. Direct attack range, about to be both or we escape of magic attack range.
・ Even if an enemy character is captured within the attackable range, it will not attack.
・ There is little damage even when attacked by enemy characters.
The character card placed in this area has a blue 67 as shown in FIG.

4) When a card is placed in the Magical Heal area • The corresponding character enters the Magical Heal state and moves to escape from the attack range of the enemy character. Direct attack range, about to be both or we escape of magic attack range.
・ Even if an enemy character is captured within the attackable range, it will not attack.
・ There is little damage even when attacked by enemy characters. Consumes MP. Restores 2 HP per second and consumes 1 MP.
・ When MP is lost, it becomes Guard state.
The character card placed in this area has a green 68 on the liquid crystal display as shown in FIG.

Next, details of the operation will be described.
-Character movement The movement distance when the character chases the enemy or escapes from the enemy is movement distance per frame = 1 m / (delay by character type + armor delay).
・ Time required for attack action
When a Normal Attack or Magical Attack character captures an enemy within the attackable range, a certain amount of time is required before the attack is actually activated.
Number of frames required before the attack is activated = Delay by character type + Weapon delay
* Even when attacking consecutively, the same time is required until the next attack.
・ Determining whether or not the attack is successful When the attack activation time is reached, it is determined whether or not the attack is successful.
First, the avoidance rate is obtained from the armor of the attacked character.
Avoidance rate = Against Attack Base + PerLv * Level of character on attack side Next, random number A is obtained in the range of 0-100.
here,
If the random number A> avoidance rate, the attack is successful.
If random number A <= avoidance rate, the attack fails.

・ Damage to be dealt when attack is successful Find damage to enemy character when attack is successful.
First, the maximum damage is calculated from the weapon of the character on the attack side.
Maximum damage = Attack * Character level of the attacking character Next, reduce the HP of the attacking character.
HP = HP-Maximum damage * (Random number A-Avoidance rate)
-Uncombatable state When damage accumulates and HP becomes zero, the character becomes uncombatable.
-Winning or losing The party loses the battle.

  (3) If the battle is won or lost in this manner, the party-organized battle game ends, and the game machine causes the player to select whether or not to continue the game by displaying the screen (S003). If the player selects continuation, the process returns to S001, where the party is organized again and a battle is performed. If you do not choose to continue, the game ends.

Next, the details of the party organization step of FIG. 5 will be described using the flowchart of FIG. The game control unit 47a determines whether or not a timeout has occurred after the game is started. If not timed out, control is passed to the party organization unit 47b. The party organization unit 47b reads (scans) the ID of the character card using the RFID reader / color electronic paper writer 24, 25, 26 and 27 (S101, S102). Then, only valid character card IDs are listed in the ID list (S103). The ID list is created in the RAM 51. Then, it is determined whether or not the number of ID-in lists in the ID list has become 3 (S104), and if it has become 3, it is determined whether or not the user has pressed the enter button (S105). The party organization is confirmed by pressing the enter button.
The party organization unit 47b downloads character data corresponding to each ID listed in the “ID list” from the server device (S110), and each character card is read by the RFID reader / color electronic paper writer 24, 25, 26 and 27. The design of the color electronic paper is updated (S111). For example, in the case of a Normal Attack area, a red 65 frame is displayed around the character as shown in FIG.

  On the other hand, if it is timed out in S101, the party organization unit 47b determines whether or not the number of “ID list” listings is greater than three (S106). If there are three or more, three are randomly selected from those listed in the “ID list” and the remaining are listed (S107). If the number of lists is less than 3, it is determined whether or not the number of “ID list” list-ins is less than 3 (S108). If the number is less than three, CPU card IDs corresponding to the number of the missing items are added (S109). Thereafter, the character data corresponding to each ID listed in S110 and S111 is downloaded from the server device, and the design of the color electronic paper is updated.

Next, details of the battle steps of FIG. 5 will be described using the flowchart of FIG.
When the party organization is completed, control is passed to the battle execution unit 47c. The battle execution unit 47c executes a scan (S201), and when it is detected in the Normal Attack area in this scan, it is determined whether or not the card is a character card detected in another area at the previous scan. (S202). If so, the target character card is set to the Normal Attack state (S203). Otherwise, the state corresponding to the area detected at the previous scan is maintained.
Next, when it is detected in the Magical Attack area in this scan, it is determined whether or not the card is a character card detected in another area at the previous scan (S204). If so, the target character card is put into a Magical Attack state (S205). Otherwise, the state corresponding to the area detected at the previous scan is maintained.

Further, if it is detected in the Guard area in this scan, it is determined whether or not the card is a character card detected in another area at the previous scan (S206). If so, the target character card is set to the Guard state (S207). Otherwise, the state corresponding to the area detected at the previous scan is maintained.
Furthermore, if the current scan detects in the Magical Heal area, it is determined whether or not the card is a character card detected in another area during the previous scan (S208). If so, the target character card is set in the Magical Heal state (S209). Otherwise, the state corresponding to the area detected at the previous scan is maintained.
When the state of the character card in each area is determined in this way, the battle execution unit 47c causes each character to perform an action corresponding to the area, that is, a normal attack, magic attack, defense, and magic recovery action (S210). The behavior at this time is displayed on the liquid crystal monitor 28.

As a result of the action, it is determined whether there is a character card whose display content needs to be updated (S211). That is, is there a character card that has moved the area? Has the equipment changed? Has HP and MP increased or decreased? Make a decision.
When the area is moved, the color of the edge of the character card is changed to the color corresponding to the moved area. When the equipment is changed, the character picture is changed. When HP and MP are increased or decreased, the state display is changed. Then, the design of the color electronic paper is updated (S212).
After performing the battle in this way, the battle execution unit 47c determines whether the allies have been annihilated or the other party has been annihilated (S213). The process returns to step S4 to perform scanning again, and executes S202 to S212.
If any one of them is annihilated, the character data reflecting the game result is uploaded to the server device (S214). Then, the design of the color electronic paper is updated so as to be in the state of each character of the game result (S215), and the game ends.
If the character card is removed from the card placement unit after the game is over, the power is not supplied, but the display of the color electronic paper pattern updated with the game result is maintained.

In the above embodiments, the drive control of the character card liquid crystal display unit and the ID read / write control are performed by a common RFID circuit. However, the drive control and ID of the character card liquid crystal display unit are described. It is also possible to adopt a configuration in which an RFID circuit is separately incorporated in order to control the reading and writing of each.
Although an example in which four RFID reader / writer devices are provided as card game machines corresponding to the four areas of the mounting table is shown, one RFID reader / writer device may be provided, or four or more RFID reader / writer devices may be provided. In this card game, the area can be specified by reading from any RFID reader / writer device. However, when one RFID reader / writer device covers the entire area of the mounting table, the card game is loaded. Detecting means for detecting whether it is placed in each area of the mounting table (filtering means that enables transmission / reception of radio waves only in a specific area of the mounting table and temporarily reduces transmission / reception of radio waves in other areas) It may be provided and specified.

  As shown in FIGS. 1A and 1B, a QR code is also displayed, and the state of each character card can be confirmed by reading with a portable terminal or the like. However, the present invention is implemented without displaying the QR code. Can do.
