FIG. 1 is a schematic diagram showing a configuration of an electronic card, FIG. 2 is a schematic diagram showing a configuration of a variable display area, and FIG. 3 is a block diagram showing a configuration of a data rewriting device. 4 to 8 are plan views showing variations of the electronic card.

(Electronic card)
As shown in FIG. 1, an electronic card 10 is physically separated from a data rewriting device 20 terminal for rewriting data, and stores and displays the rewritten data. It is a possible medium.
The electronic card 10 includes a data receiving terminal 11 that receives various data including card data that is rewritten and displayed from the data rewriting device 20 terminal, and a non-volatile memory that additionally records the data received by the data receiving terminal 11 12 and the variable display area 14 for displaying the card data to be displayed among the data additionally recorded in the nonvolatile memory 12 by the rewriting operation of the data rewriting device 20, and the variable display area in the electronic card 10 14 is provided with an invariant display area 13 for displaying invariant data in which displayed data cannot be rewritten.

For example, when the electronic card 10 is a card used for a traffic service, the card data is data composed of usage section data, amount data, and the like indicating a used section on board. On the other hand, the invariant data is data that is displayed in the invariant display area 13 and is not changed by an electrical signal.
Note that the card data is configured in association with the invariant data. For example, if the invariant data is an entire map showing railroad routes, the card data is related to each other so that position data indicating the current position is displayed.

The data receiving terminal 11 is arranged on the card side surface 10a of the electronic card 10 and receives various data including card data by contacting a device side terminal 25 of the data rewriting device 20 described later.
The non-volatile memory 12 is a semiconductor memory that can freely erase and write data and can maintain a record regardless of whether the power is turned on or off. The invariant display area 13 displays data that cannot be rewritten, such as card data. For example, a medium such as preprinted paper is pasted, or character data, image data, or the like is printed in advance. In addition, a handwritten area is provided, and the handwritten area is a column for writing the name of the owner, a serial number, and the like.

Note that an electronic card that does not include a nonvolatile memory can be provided in order to reduce the manufacturing unit price. In the case of such an electronic card, when the variable display area 14 is rewritten, the data before rewriting is lost from the electronic card.
On the other hand, if a non-volatile memory is omitted and an electronic card is provided with an IC chip (ROM chip that cannot rewrite data) for individual identification of the electronic card, and at the same time a storage means is provided on the data rewriting device 20 side, It is also possible to leave data to be stored in the nonvolatile memory of individual electronic cards by creating a database for each electronic card in the storage means.

The variable display area 14 is called a rewritable paper or a paper-like display, and is a medium for rewriting the display using an electric field, light, heat, magnetic field, or the like. In this embodiment, electrophoretic ink is used. As shown in FIG. 2, this is configured by providing a display layer called a microrib structure 14b between two plastic films 14a. The microrib structure 14b is disposed on two electrodes 14c disposed on the inner side of the plastic film 14a, and a blue liquid and titanium oxide particles (white electrophoretic particles and black electrophoretic particles) are placed inside the structure. Stored.

As a display principle, an electrophoresis method is adopted in which charged particles dispersed in a liquid move in the liquid in response to an external electric field. That is, when the white electrophoretic particles are on the front side of the microrib structure 14b, the variable display region 14 looks white. Here, when a negative voltage is applied to the electrode 14c disposed on the back side of the microrib structure 14b, the white electrophoretic particles are attracted to the back side, so that a blue liquid is displayed. This appears black in the variable display area 14.
In other words, when the card data is rewritten by receiving a constant voltage from the data rewriting device 20, the variable display area 14 displays the rewritten data as the latest data. The card data that has been displayed in the past is recorded in the nonvolatile memory 12 as history data, and only the latest card data is displayed in the variable display area 14.
In addition to the above electrophoretic ink, types such as a twist ball, a memory type liquid crystal, a powder transfer, and an electrochromy may be used. Further, the variable display area 14 has a memory property without rewriting and can hold a data display.

(Data rewriting device)

The device-side terminal 25 may exchange data in a non-contact manner in addition to a form in which data is exchanged by contacting the data reception terminal 11 of the inserted electronic card 10. The types of the data rewriting device 20 include a reader / writer built in a general-purpose PC used in a general home, a reader / writer externally connected to the general-purpose PC, and the like.

Next, with reference to FIG. 4 to FIG. 8, variations of the invariant display area 13 and the variable display area 14 and the positional relationship of the data receiving terminal 11 will be described.
FIG. 4A shows an example in which when the electronic card 10 is viewed from the front, the invariant display area 13 and the variable display area 14 are arranged above and below, and the display ratio of each display area is formed equal. FIG. 4B is an example in which the ratio of the variable display area 14 to the constant display area 13 is increased. The data receiving terminal 11 is arranged near the upper end portion on the back surface of the electronic card 10.
FIG. 5A shows an example in which the invariant display area 13 and the variable display area 14 are arranged on the left and right, and the display ratio of each display area is formed to be equal. FIG. 5B is an example in which the ratio of the variable display area 14 to the constant display area 13 is increased. The data receiving terminal 11 is disposed near the center of the back surface of the electronic card 10.
FIG. 6A shows an example in which the variable display area 14 is arranged above and below the invariable display area 13 and divided into three. FIG. 6B is an example in which the invariable display area 13 is arranged above and below the variable display area 14 as a reference and is divided into three. The data receiving terminal 11 is arranged near the upper end portion on the back surface of the electronic card 10.

In such a case, the data receiving terminal 11 can be arranged on the back surface of the electronic card 10 in addition to the form arranged on the card side surface 10a as shown in FIG. By arranging the data receiving terminal 11 on the back side of the card, the data receiving terminal 11 can be hidden when the electronic card 10 is viewed, which is suitable for improving the aesthetic appearance of the entire card.

  FIG. 7 shows an example in which the invariant display area 13 is arranged on the front surface of the electronic card 10 and the variable display area 14 is arranged on the back surface. FIG. 8 shows an example in which the invariant display area 13 and the second variable display area 19 are arranged on the front surface of the electronic card 10 and the variable display area 14 is arranged on the back surface. These are provided with display areas on both sides of the electronic card 10. For this reason, it is preferable to arrange the data receiving terminal 11 on the side surface of the card.

FIG. 9 is an example in which only the variable display area 14 is arranged on both the front and back surfaces of the electronic card 10. That is, the electronic card 10 of FIG. 9 does not include the invariant display area 13, but if only the variable display area 14 is arranged, more rewritable data can be displayed.

Although not shown, there are other forms as follows. A form in which the display areas arranged on the front and back sides of the electronic card 10 shown in FIGS. 7 and 8 are reversed, and the invariable display area 13 and the variable display area 14 of the electronic card 10 shown in FIG. There are forms such as the display areas shown in FIGS.
In other words, the above configuration is preferable because the location and size of the variable display area 14 can be adjusted according to the usage pattern of the electronic card 10, which is excellent in convenience.

The operation when the card data is displayed in the variable display area 14 is as follows.
First, when the electronic card 10 is inserted into the card insertion slot 21 of the data rewriting device 20, the data receiving terminal 11 contacts the device side terminal 25 of the data rewriting device 20, so that the electrode 14 c of the electronic card 10 is positive. Or a negative voltage is loaded. Then, the charged particles (white particles, titanium oxide particles) are attracted to one electrode 14 c to rewrite the card data, and the card data is displayed in the variable display area 14.

Further, in order to record the card data in the nonvolatile memory 12, the control unit 22 of the data rewriting device 20 expands the card data in the storage unit 23, and the nonvolatile data is transmitted from the device side terminal 25 through the data receiving terminal 11. Card data is recorded in the memory 12. In the nonvolatile memory 12, a history before being rewritten is recorded as history data. The recorded history data can be browsed by using the data rewriting device 20.

The electronic card of the present invention is a medium capable of rewriting data in the variable display area 14 unlike a method of adding data on the back side of the card like a magnetic card. Even in the limited display area of the variable display area 14, the data is rewritten without being additionally written, so that data having a higher degree of freedom than the magnetic card can be displayed and updated. In addition, since the data is rewritten by the data rewriting device 20, the electronic card 10 does not require a power supply alone and can rewrite the data in the variable display area 14, so that it is lightweight and convenient to carry.
The card data displayed in the variable display area 14 is associated with the invariant data in the invariant display area 13. For this reason, information combining invariant data and card data can be created, such as “map” and “current position”.

(Electronic card with folder)
FIG. 10 is a diagram illustrating an example of the electronic card 100 with a folder.
The folder-attached electronic card 100 includes a folder main body 60 that can be folded in half with respect to a center line. It has. The card storage sheet 61 is composed of a left sheet 61a positioned on the left side and a right sheet 61b positioned on the right side as viewed from the front in FIG. 10. Although not shown, the card storage sheet 61 is provided when the card storage sheet 61 is turned in a predetermined direction. Sheets similar to 61 are provided in an overlapping manner.

The terminal cover 62 is formed of an insulator that does not transmit electrical energy to the data receiving terminal 11. As shown in FIG. 11, when the electronic card 10 is accommodated in the terminal cover 62, the lower end of the electronic card 10 to the data receiving terminal 11 are covered, and a part of the upper end of the electronic card 10 is exposed to the outside. It has become a form. For this reason, the terminal cover part 62 can protect the data receiving terminal 11 reliably, and prevents the loss of the card | curd data recorded on the electronic card 10. FIG. Further, since the upper end of the electronic card 10 is exposed, when the electronic card 10 is taken out, it can be easily taken out by grasping a part of the upper end.

Further, as shown in FIG. 12, a polarizing film 63 is provided in a part of the terminal cover portion 62. The polarizing film 63 is made of a transparent or translucent material, and the card data displayed in the variable display area 14 becomes invisible when viewed from a certain angle. Specifically, when the user using the folder main body 60 looks at the electronic card 10 from the front, the card data can be visually recognized as usual, but from an angle deviated from the front, for example, about 30 degrees from top to bottom, left and right. When viewed, the card data cannot be viewed.
That is, the card data of the electronic card 10 accommodated in the folder main body 60 cannot be read from other users. As a usage form of the electronic card with folder 100, for example, a battle-type card game is performed in a state where the electronic card is accommodated in the folder main body 60. In this case, since the card data is not visible to the other party, it is possible to enjoy a battle-type card game with other users.

It is also possible to provide only a folder alone. This is configured to include a terminal cover portion 62 of an insulator that accommodates part or all of the electronic card 10 and protects the position where the data receiving terminal 11 reaches when the electronic card 10 is properly stored. . In addition, when there are a plurality of standardized sizes of electronic cards, a plurality of types of folders can be provided according to the standards. In addition, a notebook with a filing structure capable of storing a plurality of electronic cards one by one can be provided.

(Online card game system)
Next, an online card game using the electronic card 10 described above will be described with reference to FIGS.
In the online card game system according to the embodiment of the present invention, a plurality of characters called a “card battle” are competing against a plurality of users online using the Internet under a predetermined rule. In a turn-based competitive card game, in order to perform a “card battle”, a readable / writable electronic card 10 is inserted into a terminal that can be connected to the Internet, and the card data necessary for the “card battle” is stored. It is done by reading.

The overall flow will be described with reference to FIG. 13. In order to perform “card battle” with the user B who is another user online, the user A terminal 40 (sender terminal) according to the user A Is used to transmit a battle request to the server 50. When the server 50 receives the battle request, the server 50 transmits the battle request to the terminal 40b (match candidate terminal) related to the user B. When the user B accepts the battle with the user A, the electronic card 10 is inserted into the terminal 40 and the terminal 40b, the card data is read, updated to the latest data, and setting is performed. When the preparation is completed, a “card battle” by the user A and the user B is started under a predetermined rule.

When the “card battle” ends, the server 50 records the battle result as a battle history in the battle history database 51. When the card data of the electronic card 10 is updated by the “card battle”, the update data is recorded in the update database 52, the recorded update data is transmitted to the electronic card 10, and the card data Rewrite.

  The card data in this system indicates various data necessary for the “card battle” composed of the ability value, feature points, and battle history of the character of the electronic card 10. As shown in FIG. 14, the ability value consists of [level], [physical strength], [speed], [magic power], and [power], and the characteristic points include [deadly skill] and [skills] specific to the character. ] And various data such as [weapons] already installed. The battle history is data in which detailed results of “card battles” played against past users are recorded as history, and this battle history can be viewed using a terminal.

  In the invariant display area 13 in this system, data such as a predetermined character image and character name related to the card game are displayed. That is, data that does not change like card data is displayed even if a “card battle” is performed.

The variable display area 14 in this system displays card data such as [level], [physical strength], [speed], etc. displayed in the variable display area 14, and the card data is updated by "card battle". Then, the displayed data is rewritten to the latest card data.
Further description will be made with reference to FIG. 14. The left side of FIG. 14 is the state of the ability value before the start of the “card battle”, and the right side is the state of the ability value after the end of the “card battle”. [Power] is “80” before the start of “Card Battle”, but it is assumed that power has increased by 20 points because certain conditions such as victory have been achieved from other users in “Card Battle”. As a result, in the variable display area 14 after the completion of the “card battle”, it is understood that the “power” is increased from “80” to “100”.

As shown in FIG. 15A, the terminal 40 used in this system is installed in a user's house or the like and installed in a home PC, a home game machine, a retail store, or the like with a built-in card slot. A retail terminal that is always connected to the server 50 via the Internet, a portable terminal that is connected to a home PC (home game machine) via a predetermined interface (for example, a USB port), and can be carried by removing the terminal 40 There is.
As shown in FIG. 15B, when a portable terminal is used, the portable terminal may be connected to the retail store terminal. If the terminal 40 is of a portable type, the game is not limited to an online game, and an offline card game in which users play by bringing cards together can be performed, and the selection range of play conditions can be expanded.

Next, each process of the server 50, the terminal 40, and the terminal 40b according to the present system will be described with reference to FIGS. In the present embodiment, it is assumed that the terminal 40 and the terminal 40b are installed in the user's house, and the “card battle” is performed in a state where the terminal 40 and the terminal 40b are connected to the server 50 through the Internet line from the user's house. To do.

(User authentication process)
In order to use this system, first, user authentication processing is performed by either a method of accessing a website dedicated to this system using a WWW browser or the like, or a method of accessing the server 50 using dedicated software. As shown in FIG. 16, when the user A turns on the power of the terminal 40, an Internet line connection check is performed (S101). If the line connection is OK, an authentication request for user authentication is transmitted to the server 50 (S102). In the authentication, authentication data necessary for authentication such as a user ID and a password is transmitted. The server 50 performs user authentication processing based on the transmitted authentication data (S103). If the line connection is in error, the error is displayed on the terminal 40 and error processing is performed (S104).

After the authentication process, the terminal 40 determines whether or not the user is logged in (S105). If the user is logged in, the terminal 40 transmits a user data synchronization request to the server 50 (S106). If it is a login error, an error is displayed on the terminal 20 and error processing is performed (S107).
The server 50 synchronizes user data and server data, and transmits server update information updated by the synchronization to the terminal 40 (S108). The terminal 40 receives the data and determines whether the data has been confirmed (S109). If the confirmation has been made, the connection is completed. If the data has not been confirmed, an error is displayed on the terminal 40 and error processing is performed (S110).

(Matching process)
When the terminal 40 is normally authenticated by the user authentication process, a battle process by “card battle” is performed. As shown in FIG. 17, the user A transmits a battle content selection and a battle request from the terminal 40 (S201). The selection of battle content is a rule of “card battle”. For example, in the case of victory conditions, a rule may be considered in which a three-turn system is used and a user who has won two wins wins.

Upon receiving the battle request from the terminal 40, the server 50 transmits a battle candidate list of other users who can compete online in the online state to the terminal 40 (S202). When the user A selects a desired opponent from the competition candidate list (S203), the server 50 confirms and calls the terminal 40b of the selected opponent (here, user B) (S204). It is determined whether there is a call from the terminal 40b (S205), and if there is a response, a notification of the opponent and the battle content is transmitted to the terminal 40b (S206). If there is no response, the terminal 40 is displayed with no response, and a selection is made as to whether it is a standby process or an end process (S207).

  If the response corresponds to the response, the terminal 40b performs the user authentication and data synchronization processing shown in FIG. 16 (S208), and receives the application for “card battle” from the user A based on the opponent and the content of the battle. Whether or not is selected (S209). The server 50 determines whether or not the user B has received the application (S210), and if accepted, registers and initializes the battle content (S211). If the “card battle” is rejected, the terminal 40 displays a battle rejection message and ends the cancel process (S212).

  If the setting of “card battle” is set by registering and initializing the battle content, the fact is transmitted to the terminal 40 and the terminal 40b (S213). Each user inserts the electronic card 10 into the terminal 40 (40b). Card data is read by the terminal 40 (40b), and the read card data is transmitted to the server 50. The server 50 performs battle processing from the received card data (S214). In the battle process, situation data that is a battle situation is transmitted to the terminal 40 and the terminal 40b in real time (S215). The situation data is displayed on the terminal 40 and the terminal 40b and written to the electronic card 10 as a battle history (S216). For example, in the first turn, the user A has won using a OO card.

  The server 50 determines whether or not the “card battle” between the user A and the user B is determined based on the content of the battle (S217). If the result is determined, the card data is recorded in the update database 52. And register (S218). If no win or loss is found, a “card battle” is repeated until the battle end condition (S219). After registering the card data, the connection with the terminal 40 and the terminal 40b is released, and the process ends (S220). The terminal 40 and the terminal 40b are terminated when the connection with the server 50 is released and the end of the “card battle” is displayed on the terminal 40 (S221).

  Next, another embodiment of the present system will be described. FIG. 18 is a flowchart for explaining processing in a form in which a plurality of retail stores in each region hold a “card battle tournament” and the retail store terminals installed in each retail store are always connected to the server 50. Here, it is assumed that user A and user B are in different retail stores, and a user who participates in the “card battle tournament” purchases a portable terminal and an electronic card 10 as needed at a retail store, and other users And “card battle”. In addition, as a rule of the “card battle tournament”, it is assumed that the battle content is set to a 3-turn system. The user authentication process is the same as that shown in FIG.

  When the portable terminal 30 associated with the user A makes a battle application to the server 50 via the retail store terminal, the battle candidate list participating in the tournament is transmitted from the server 50. This battle candidate list is created by listing the terminals that can be played by the battle candidate list creation means. For this reason, it is possible to select the opponent desired by the user himself. When the user A selects the user B and applies for a battle, the server 10 calls the portable terminal 30b related to the user B and transmits a battle request from the user A. If the user B approves, the card data is updated to the latest data and the data is initialized (S301).

(First turn)
The portable terminal 30 (30b) reads the card data of the first electronic card 10 selected by the user A and the user B (S302), and battle processing is performed via the retail store terminal. When winning or losing is determined from the read card data, if the card data of the electronic card 10 is changed from the result, the changed data is written in the electronic card 10 as update data (S303). Here, it is assumed that the user B has won.

(2nd turn)
The portable terminal 30 (30b) reads the data for the card of the second electronic card 10 selected by the user A and the user B (S304), and battle processing is performed via the retail store terminal. When the ten card data is changed, the changed data is written in the electronic card 10 as update data (S305). It is assumed that user A has won in the second turn.

(Third turn)
The portable terminal 30 (30b) reads the data for the card of the third electronic card 10 selected by the user A and the user B (S306), and battle processing is performed via the retail store terminal. When the data for 10 cards is changed, the changed data is written in the electronic card 10 as update data (S307). Since the user A won even in the third turn, the user A will remain victorious according to the rules of the “card battle tournament”, and the user A can fight other users.

The system can also be processed as software. In this case, a battle request reception procedure for receiving a battle request from the terminal 40 that desires an online battle, a battle request transmission procedure for transmitting the battle request received by the battle request reception procedure to the terminal 40b that can be a battle candidate, When receiving a battle request from the terminal 40b, a card data receiving procedure for receiving the card data of the electronic card 10 inserted into each of the terminal 40b and the terminal 40, and the received card data and terminal of the terminal 40b 40 card data are compared based on a predetermined rule, a battle processing procedure for determining a winner and a loser and calculating a battle result data, and the battle processing procedure changes the card data for the winner or loser. The changed data is written in the electronic card 10 as update data, and the update data can be displayed in the variable display area 14. It is processed by a program to be executed and the data rewriting procedure for de, to the computer.

In addition, the above program detects a terminal capable of online battle as a battle candidate terminal, sends a battle candidate list creation procedure for listing the detected battle candidate terminals, and an online battle request for the battle candidate list. And a battle candidate list transmission procedure for transmitting to the transmission side terminal.

In addition, a battle request data receiving procedure for receiving the battle request data that the transmitting terminal desires to battle from the battle candidate list, and an online battle with the transmitting terminal for the battle candidate terminal related to the battle request data. A battle permission transmission procedure for inquiring whether or not to accept, and a setting procedure for setting a battle preparation between the battle candidate terminal and the transmission side terminal when the battle candidate terminal accepts the battle permission.

Further, the above computer program can be provided by being stored in a recording medium. Here, the “recording medium” is a medium that can carry a program that cannot occupy space by itself, such as a flexible disk, a hard disk, a CD-R, an MO (magneto-optical disk), a DVD- R and the like. It is also possible to transmit from a computer storing a program according to these inventions to another computer through a communication line.
