  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a block diagram showing a configuration example of a communication system 100 to which the present invention is applied. In the figure, an IC card 101 is configured as a non-contact IC card, for example, and configured to be able to perform wireless communication with the reader / writer 102.

  The IC card 101 receives, for example, an electromagnetic wave having a predetermined frequency radiated from a reader / writer 102 disposed in the vicinity by a loop (coil) antenna 121.

  Further, in the IC card 101, power supply power is supplied from the power supply unit 125 to the control unit 122 that controls the execution of various processes performed with the reader / writer and controls the storage of data accompanying the process. It is made so that.

  For example, the power generation unit 123 resonates with an electromagnetic wave received by an LC circuit including an antenna 121 and a capacitor (not shown), rectifies an AC magnetic field excited in the antenna 121, and stabilizes it with a voltage regulator or the like. And output to the power supply unit 125 as DC power.

  The solar cell unit 124 is configured to be able to obtain power supply power by photoelectric conversion by sunlight received by a light receiving unit (not shown) or light emitted from another light source. Output to the power supply unit 125.

  Then, the power supply unit 125 supplies the power supply power output from the power generation unit 123 or the solar cell unit 124 to the control unit 122. In addition, the power supply unit 125 outputs information indicating whether the power supply power is output from the power generation unit 123 or the solar cell unit 124 to the control unit 122 as necessary.

  The electromagnetic wave received via the antenna 121 is supplied to the modulation / demodulation unit 142 via the transmission / reception unit 141 of the control unit 122. For example, the modulation / demodulation unit 142 detects and demodulates a modulated wave (ASK modulated wave) received via the antenna 121 by performing envelope detection, performs BPSK (Binary Phase Shift Keying) on the demodulated data, and outputs the data to the CPU 144.

  When transmitting predetermined information to the reader / writer 102, the transmission / reception unit 141 performs ASK modulation on the data supplied from the CPU 144 by the modulation / demodulation unit 142, and the modulation component is transmitted to the reader / writer 102 via the antenna 121. Send.

  The CPU 144 executes a control program stored in the ROM 143 and controls the entire operation of the IC card 101. For example, when the electromagnetic wave radiated from the reader / writer 102 is received by the antenna 121, the CPU 144 notifies the reader / writer 102 of information including the card identification number set in the IC card 101 or the like accordingly. In response to a request from the reader / writer, information necessary for transaction processing is supplied to the reader / writer 102.

  The data memory 145 stores data generated in accordance with the execution of processing by the CPU 144, data transmitted from the reader / writer 102, and the like. The CPU 144 writes (including erases) or reads data to the data memory 145. Control.

  The display switching unit 146 reads data from the data memory 145 via the CPU 144 and causes the display unit 147 to display the read data.

  The display unit 147 is configured as a display such as an LCD (Liquid Crystal Display), for example, and displays an image based on a control signal supplied from the display switching unit 146.

  The display unit 147 may be configured by electronic paper. In this way, the IC card 101 can be configured to be thinner and smaller.

  As described above, the antenna 220 of the reader / writer 102 radiates electromagnetic waves of a predetermined frequency to the nearby IC card 101 and receives the electromagnetic waves transmitted from the antenna 121 of the IC card 101 to the transmitting / receiving unit 221. Supply.

  The transmission / reception unit 221 transmits a signal obtained by modulating the data output from the CPU 223 via the modulation / demodulation unit 222 to the IC card 101 via the antenna 220. Also, the transmission / reception unit 221 supplies a signal acquired via the antenna 220 to the modulation / demodulation unit 222, and the modulation / demodulation unit 222 demodulates the signal and supplies it to the CPU 223 as data.

  The CPU 223 executes a control program stored in the ROM 224 and controls the overall operation of the reader / writer 102. For example, when the electromagnetic wave transmitted from the IC card 101 is received by the antenna 220, the CPU 223 executes a transaction process or the like accordingly, and transmits information regarding the process to the IC card 101 as necessary.

  The data memory 225 stores data generated in accordance with the execution of processing by the CPU 223, data transmitted from the IC card 101, and the like. The CPU 223 writes (including erases) or reads data to and from the data memory 225. Control.

  The external control unit 226 controls the operation of the external device 227 connected to the reader / writer 102 based on a command from the CPU 223.

  The external device 227 is a device configured to operate based on the control of the reader / writer 102. For example, when the IC card 101 is used as a train ticket, the external device 227 is configured as an automatic ticket gate. The The reader / writer 102 is incorporated in the automatic ticket checker, and controls the opening / closing operation of the automatic ticket checker based on the information stored in the IC card 101, for example. In addition, the reader / writer 102 is configured to be incorporated into various devices according to the use of the IC card 101, such as terminals such as various gates and store registers.

  Next, processing (operation) of the IC card 101 will be described with reference to the flowchart of FIG.

  In step S <b> 101, the power supply unit 125 determines whether there is communication from the reader / writer 102 by determining whether power is supplied from the power generation unit 123, for example. If it is determined in step S101 that there is no communication from the reader / writer 102, the process proceeds to step S102.

  In step S102, the power supply unit 125 determines whether power is supplied from the solar cell unit 124. If it is determined that power is not supplied from the solar cell unit 124, the process returns to step S101. If it is determined in step S102 that power is supplied by the solar cell unit 124, the process proceeds to step S103.

  In step S103, the display switching unit 146 reads data to be displayed from the data memory 145 via the CPU 144.

  In step S104, the display switching unit 146 causes the display unit 147 to display the data read out in the process of step S103.

  After the process of step S104, the process returns to step S101.

  On the other hand, if it is determined in step S101 that there is communication from the reader / writer 102, the process proceeds to step S105, and a card type handling process is executed. Details of the card type handling process will be described later.

  In step S <b> 106, the CPU 144 determines whether or not a reset associated with the execution of the card type handling process has been performed, and waits until it is determined that the reset has been performed. If it is determined in step S106 that the reset has been made, the process returns to step S101.

  As described above, only when it is determined that there is no communication from the reader / writer 102 (no power source power is output from the power generation unit 123) and the power source power is output from the solar cell unit 124, data display is performed. Will be done. As described above, the power generation unit 123 generates power when it is brought close to the reader / writer 102. For example, power cannot be supplied at a location away from the reader / writer. In addition, since the power generation unit 123 generates power by rectifying the AC magnetic field excited in the antenna 121, the power supplied thereby is weak, and processing such as communication with the reader / writer 102 is performed. It should be provided to.

  In the present invention, information is displayed on the display unit 147 only when no power source power is output from the power generation unit 123 and power source power is output from the solar cell unit 124. It is possible to display predetermined information corresponding to the data from the data memory 145 on the display unit 147 without hindering the processing such as the communication. Since the solar cell unit 124 generates electric power by photoelectrically converting the received light, information cannot be displayed on the display unit 147 unless it is a bright place, but the user is originally displayed on the display unit 147. When confirming the information, it is considered that the information is confirmed in a bright place. Therefore, when the solar cell unit 124 cannot generate power, even if the information cannot be displayed, the convenience for the user is not impaired.

  Moreover, since the data updated by the process of step S105 is read from the data memory 145 and displayed on the display unit 147, it is possible to always present appropriate information to the user.

  In this example, in step S101, it is determined whether or not there is communication from the reader / writer 102. However, as described above, whether the power supply unit 125 has supplied power from the power generation unit 123 or not. A determination of whether or not may be made. Similarly, in the process of step S106, it may be determined whether the supply of power from the power supply unit is stopped in the same meaning as the determination of whether the reset has been performed. That is, the processes in steps S101 and S106 can be executed independently even when the CPU 144 is executing other processes.

  Therefore, actually, even if the IC card 101 is brought close to the reader / writer 102 and receives power supply via the antenna 121 even during the processing of steps S102 to S104, the currently executed step S102 is performed. In other words, the process of S104 to S104 is forcibly terminated, and the execution of the process of step S105 is started.

  In step S105, a card type handling process is executed as described later. This process is a process of writing data stored in the IC card 101 based on communication with the reader / writer 102. The process differs depending on the usage mode (card type) of the IC card 101. Become.

  First, an example in which the IC card 101 is used as a train ticket will be described. When the IC card 101 is used as a train ticket, the card type correspondence process 1 shown in FIG. 3 is executed in step S105 of FIG. When the IC card 101 is used as a train ticket, the reader / writer 102 is incorporated in, for example, an automatic ticket gate or a terminal installed at a store in a station.

  Here, the details of the card type correspondence processing 1 will be described with reference to the flowchart of FIG.

  In step S201, the CPU 144 determines whether communication with the reader / writer 102 is possible, and waits until it is determined that communication with the reader / writer 102 is possible. If it is determined in step S201 that communication with the reader / writer 102 is possible, the process proceeds to step S202.

  In step S202, the CPU 144 performs communication with the reader / writer 102. Thus, transaction processing or the like is executed in response to a request from the reader / writer 102.

  In step S203, the CPU 144 determines the type of processing such as a transaction to be executed based on communication with the reader / writer 102 in step S202. In this case, since the IC card 101 is used as a train ticket, it is assumed that there are three types (types) of processing: ticket gate entry, ticket gate exit, or prepaid card.

  Here, the ticket gate entry is a process executed when the user who has the IC card 101 passes through the automatic ticket gate and enters the station (home), for example. This is a process executed when the possessed user leaves the station (home) through the automatic ticket gate. The prepaid card is a process executed when the IC card 101 is used as a prepaid card and a small amount is purchased at a store in a station.

  If it is determined in step S203 that the process type is ticket gate entry, the process proceeds to step S204.

  In step S204, the CPU 144 determines whether or not the balance is sufficient. Here, the balance is, for example, a prepaid balance that is charged to the IC card 101 when the user inserts a predetermined amount into a dedicated device or the like, and is a small amount at a train fare or at a station shop, etc. It is assumed that the purchase price or the like is settled by reducing the prepaid balance.

  If it is determined in step S204 that the balance is sufficient, the process proceeds to step S205. In step S205, the CPU 144 writes information such as the entrance station code, the current date and time, the updated balance, and history information in the data memory 145.

  Here, the entrance station code is a code composed of information for specifying the station name and information indicating that the station has entered from the station. Further, since the minimum necessary amount is collected at the entrance to the ticket gate, the amount is reduced from the balance and written as updated balance information. The history information is predetermined information written as needed, such as information on the automatic ticket gates that have passed.

  FIG. 4 is a diagram showing a display example of the display unit 147 at this time. In the figure, the display unit 147 displays “On: Shinjuku”. This is information displayed by specifying that the user has entered from “Shinjuku Station” based on the entrance station code written in the process of step S205 described above.

  The display unit 147 displays “Balance: ¥ 12,345”. This is information displayed by specifying that the balance currently charged in the IC card is 12,345 yen based on the updated balance written in the process of step S205 described above.

  The display unit 147 displays “06/06/14 10:12”. This is specified and displayed based on the date and time information written in the process of step S205 described above, that the process was executed at 10:12 on June 14, 2006 (that is, entered). Information.

  On the other hand, if it is determined in step S204 that the balance is insufficient, the process proceeds to step S210, and a predetermined error process is executed.

  If it is determined in step S203 that the process type is ticket gate exit, the process proceeds to step S206.

  In step S206, the CPU 144 determines whether or not the balance is sufficient.

  If it is determined in step S206 that the balance is sufficient, the process proceeds to step S207. In step S207, the CPU 144 writes information such as the exit station code, the current date and time, the updated balance, and history information in the data memory 145.

  Here, the exit station code is a code composed of information for specifying a station name and information indicating that the station has exited. Further, since the difference between the balance reduced at the entrance of the ticket gate and the actual fare is further collected with the exit of the ticket gate, the amount is further reduced from the balance and written as updated balance information.

  FIG. 5 is a diagram showing a display example of the display unit 147 at this time. In the figure, the display unit 147 displays “Exit: Gotanda”. This is information that is identified and displayed based on the exit station code written in the process of step S207 described above and that it has exited at “Gotanda Station”.

  The display unit 147 displays “Balance: ¥ 10,000”. This is information displayed by specifying that the balance currently charged in the IC card is 10,000 yen based on the updated balance written in the process of step S207 described above.

  Further, “06/06/14 10:27” is displayed on the display unit 147. This is specified and displayed based on the date and time information written in the process of step S207 described above, that the process was executed at 10:27 on June 14, 2006 (ie, exited). Information.

  On the other hand, when it is determined in step S206 that the balance is insufficient, the process proceeds to step S210, and a predetermined error process is executed.

  If it is determined in step S203 that the process type is prepaid (card), the process proceeds to step S208.

  In step S208, the CPU 144 determines whether or not the balance is sufficient when paying for the purchase.

  If it is determined in step S208 that the balance is sufficient, the process proceeds to step S209. In step S209, the CPU 144 writes information such as the updated balance and history information in the data memory 145.

  For example, after shopping at the ticket gate (step S204) and before leaving the ticket gate (step S206), if you shop at a store in the station, the balance is reduced and written for the purchase price. However, the entrance station code and the information on the date and time of entry are not updated.

  FIG. 6 is a diagram showing a display example of the display unit 147 at this time. In the figure, the display unit 147 displays “On: Shinjuku”. This is information that is specified and displayed as having entered from “Shinjuku Station” based on the entrance station code written in step S205 described above.

  The display unit 147 displays “Balance: ¥ 10,000”. This is information displayed by specifying that the balance currently charged in the IC card is 10,000 yen based on the updated balance written in the process of step S209 described above.

  The display unit 147 displays “06/06/14 10:12”. This is specified and displayed based on the date and time information written in the process of step S205 described above, that the process was executed at 10:12 on June 14, 2006 (that is, entered). Information.

  On the other hand, when it is determined in step S208 that the balance is insufficient, the process proceeds to step S211 and a predetermined error process is executed.

  After the process of step S205, S207, S209, S210, or S211, the process proceeds to step S212, and the IC card 101 is reset.

  In this way, ticket gate entry, ticket gate exit, or prepaid processing is executed on the IC card 101 used as a boarding ticket, and information based on the stored data is displayed on the display unit 147 according to the processing result.

  Next, an example in which the IC card 101 is used as a train commuter pass will be described. When the IC card 101 is used as a commuter pass, the card type corresponding process 2 shown in FIG. 7 is executed in step S105 of FIG. When the IC card 101 is used as a commuter pass, the reader / writer 102 is also incorporated into an automatic ticket gate or a terminal installed at a store in a station.

  Here, details of the card type correspondence processing 2 will be described with reference to the flowchart of FIG.

  Since the processes in steps S241 and S242 are the same as the processes in steps S201 and S202 in FIG. 3, detailed description thereof will be omitted.

  In step S243, the CPU 144 determines the type of processing such as a transaction to be executed based on communication with the reader / writer 102 in step S242. In this case, since the IC card 101 is used as a commuter pass, it is assumed that there are three types (types) of processing: ticket gate entry, ticket gate exit, or prepaid card.

  If it is determined in step S243 that the process type is ticket gate entry, the process proceeds to step S244.

  In step S244, the CPU 144 determines whether or not entry is possible. Specifically, for example, the information stored in the IC card 101 is transmitted to the reader / writer 102 in the process of step S242, and the reader / writer 102 can get on the commuter pass (IC card 101), the valid period, Etc., and information indicating admission permission is transmitted to the IC card 101. In step S244, it is determined whether or not admission is possible based on information indicating whether or not admission is transmitted from the reader / writer 102.

  If it is determined in step S244 that admission is possible, the process proceeds to step S245. In step S245, the CPU 144 writes information such as an entrance station code, the current date and time, the number of remaining days, operation information, and history information in the data memory 145.

  Here, the entrance station code is a code composed of information for specifying the station name and information indicating that the station is entered from the station as described above. The remaining number of days is the number of remaining days until the date when the commuter pass is valid. The operation information is information relating to the operation status of the route used by the commuter pass, and is information indicating, for example, how much delay is currently occurring. Note that the operation information is acquired by the reader / writer 102 communicating with a server or the like used in an operation monitoring system of a railway company, for example, and transmitted to the IC card 101 by the process of step S242.

  FIG. 8 is a diagram showing a display example of the display unit 147 at this time. In the figure, the display unit 147 displays “On: Shinjuku”. This is information displayed by specifying that the user has entered from “Shinjuku Station” based on the entrance station code written in the process of step S245 described above.

  The display unit 147 displays “Balance: ¥ 12,345”. This is information that is displayed based on the data read from the data memory 145, specifying that the balance currently charged in the IC card is 12,345 yen.

  Further, the display unit 147 displays “Number of remaining days: 10 days”. This is information that is specified and displayed based on the information on the number of remaining days written in the process of step S245 described above that the number of remaining days until the expiration date of the commuter pass is 10 days.

  The display unit 147 displays “xxx line: delay”. This is information that is displayed based on the operation information written in the process of step S245 described above, specifying that there is a delay (delay) in “XXX line”.

  On the other hand, if it is determined in step S244 that admission is not possible, the process proceeds to step S250, and a predetermined error process is executed.

  In addition, in the case of entrance from a station other than the section where the commuter pass (IC card 101) can be boarded, an error may be made in the process of step S250, but the process of step S204 in FIG. It may be executed to allow entry to the ticket gate.

  If it is determined in step S243 that the process type is ticket gate exit, the process proceeds to step S246.

  In step S246, the CPU 144 determines whether it is possible to leave. Specifically, for example, the information stored in the IC card 101 is transmitted to the reader / writer 102 in the process of step S242, and the reader / writer 102 can get on the commuter pass (IC card 101), the valid period, The information indicating whether or not to leave is transmitted to the IC card 101. In step S246, it is determined whether or not leaving is possible based on the information indicating whether or not leaving is transmitted from the reader / writer 102.

  If it is determined in step S246 that leaving is possible, the process proceeds to step S247. In step S247, the CPU 144 writes information such as the exit station code, the current date and time, the number of remaining days, transfer information, and history information in the data memory 145.

  Here, the exit station code is a code composed of information for specifying the station name and information indicating that the station has exited as described above. The remaining number of days is the number of remaining days until the date when the commuter pass is valid. The transfer information is, for example, information related to a route to be transferred when there are a plurality of routes used in the commuter pass.

  FIG. 9 is a diagram showing a display example of the display unit 147 at this time. In the figure, the display unit 147 displays “Exit: Gotanda”. This is information that is identified and displayed based on the exit station code written in the process of step S247 described above and that it has exited at “Gotanda Station”.

  The display unit 147 displays “Balance: ¥ 10,000”. This is information that is displayed based on the data read from the data memory 145, specifying that the balance currently charged in the IC card is 10,000 yen.

  Further, the display unit 147 displays “Number of remaining days: 10 days”. This is information displayed by specifying that the remaining number of days until the expiration date of the commuter pass is 10 days based on the information on the number of remaining days written in the process of step S247 described above.

  The display unit 147 displays “XXX line transfer”. This is information that is displayed based on the transfer information written in the process of step S247 described above, after which it is specified to change to the “XXX line”.

  On the other hand, if it is determined in step S246 that it is not possible to leave, the process proceeds to step S250, and a predetermined error process is executed.

  In the case of leaving from a station other than the boarding area with the commuter pass (IC card 101), an error may be made in the process of step S250, but the process of step S206 in FIG. It may be executed to permit exit of the ticket gate.

  If it is determined in step S243 that the process type is prepaid (card), the process proceeds to step S248.

  In step S248, the CPU 144 determines whether or not the balance is sufficient when paying for the purchase.

  If it is determined in step S248 that the balance is sufficient, the process proceeds to step S249. In step S249, the CPU 144 writes information such as the updated balance, the number of remaining days, history information, and operation information in the data memory 145.

  For example, after shopping at the ticket gate (step S244) and before leaving the ticket gate (step S246), if you shop at a store in the station, etc., the balance will be reduced and written for the purchase price. The entrance station code will not be updated.

  FIG. 10 is a diagram showing a display example of the display unit 147 at this time. In the figure, the display unit 147 displays “On: Shinjuku”. This is information displayed by specifying that the user has entered from “Shinjuku Station” based on the entrance station code written in the process of step S245 described above.

  The display unit 147 displays “Balance: ¥ 10,000”. This is information displayed by specifying that the balance currently charged in the IC card is 10,000 yen based on the updated balance written in the process of step S249 described above.

  Further, the display unit 147 displays “Number of remaining days: 10 days”. This is information that is specified and displayed based on the information on the number of remaining days written in the process of step S245 described above that the number of remaining days until the expiration date of the commuter pass is 10 days.

  The display unit 147 displays “xxx line: recovery”. This is information displayed by specifying that the delay (delay) of “xxx line” has been recovered based on the operation information written in the process of step S249 described above.

  On the other hand, if it is determined in step S248 that the balance is insufficient, the process proceeds to step S251, and a predetermined error process is executed.

  After the process of step S245, S247, S249, S250, or S251, the process proceeds to step S252, and the IC card 101 is reset.

  In this way, ticket gate entry, ticket gate exit, or prepaid processing is executed in the IC card 101 used as a commuter pass, and information based on the stored data is displayed on the display unit 147 according to the processing result.

  Next, an example in which the IC card 101 is a reserved seat ticket used together with a train ticket and used as a reserved seat ticket used on an express train or the like will be described. Here, for example, a reserved seat ticket is purchased by a user who uses a reserved seat on an express train or the like by placing a price in a dedicated ticket machine in advance, and the purchased reserved seat ticket is an IC It is assumed that data is stored in the card 101. When the IC card 101 is used as a reserved seat ticket, the card type corresponding process 3 shown in FIG. 11 is executed in step S105 of FIG.

  Here, the details of the card type correspondence processing 3 will be described with reference to the flowchart of FIG.

  Since the processes of steps S301 and S302 are the same as the processes of steps S201 and S202 of FIG. 3, detailed description thereof will be omitted.

  In step S303, the CPU 144 determines whether or not the process such as a transaction executed based on the communication with the reader / writer 102 in step S302 is a ticketing process. Here, the ticketing is a process executed in conjunction with the purchase of the reserved seat ticket. If it is determined in step S303 that the ticket is issued, the process proceeds to step S304. In this case, the reader / writer 102 is incorporated in a dedicated ticket vending machine.

  In step S304, the CPU 144 writes information such as a boarding section, a train number, a departure date and time, a seat number, a home number, an updated balance, and operation information in the data memory 145.

  Here, the boarding section is the information indicating the section where the train can be boarded with the designated seat ticket, such as the station name, the train number is the number identifying the train that can be boarded with the designated seat ticket, etc. The date and time when the train is scheduled to depart. The seat number is the number that identifies the seat reserved by the designated seat ticket, and the home number is the number that identifies the platform of the station where the train that can be boarded by the designated seat ticket arrives at the boarding station. It is said. Furthermore, the updated balance is the balance updated by subtracting the price of the reserved seat ticket from the prepaid balance charged in the IC card 101, and the operation information includes the operation status of the train that can be boarded by the reserved seat ticket, etc. It is information about.

  In addition, it may replace with the home number mentioned above and may be made to write the information of a train number (for example, (circle) car etc.).

  FIG. 12 is a diagram showing a display example of the display unit 147 at this time. In the figure, the display unit 147 displays “Tokyo-Osaka”. This is based on the information on the boarding section written in the processing of step S304 described above, and it is specified and displayed that the section where the reserved seat ticket can board the train is from "Tokyo Station" to "Osaka Station". Information.

  The display unit 147 displays “10: 00-16: 00”. This is because, based on the departure date / time information written in the process of step S304 described above, a train that can be boarded with the reserved seat ticket departs (departs) “Tokyo Station” at 10:00, and arrives at “Osaka Station” at 16:00. It is the information that has been identified and displayed to arrive. Note that the arrival time is automatically calculated by the CPU 144 based on the departure time and the boarding section, for example.

  Further, the display unit 147 displays “7th line A17 seat”. This is because, based on the information of the home number written in the processing of step S304 described above, the train that can be boarded by the reserved seat ticket is the platform of the station that arrives at the boarding station is No. 7, and the train of step S304 Based on the seat number information written in the process, the seat reserved by the designated seat ticket is identified and displayed as A17 seat.

  The display unit 147 displays “Normal operation”. This is information that is displayed on the basis of the operation information written in the process of step S304 described above, specifying that the train that can be boarded by the designated seat ticket is operating normally.

  After the process of step S304, or when it is determined in step S303 that the process is not ticketing, the process proceeds to step S305.

  In step S305, the CPU 144 determines the type of processing such as a transaction to be executed based on communication with the reader / writer 102 in step S302. In this case, since the IC card 101 is used as a reserved seat ticket, it is assumed that there are three types (types) of processing such as ticket gate entry, ticket gate exit, or ticket check as processing types. Here, the reader / writer 102 is incorporated in an automatic ticket checker or a terminal for ticket check used in a train.

  If it is determined in step S305 that the process type is ticket gate entrance, the process proceeds to step S306.

  In step S306, the CPU 144 determines whether or not entry is possible. Specifically, for example, in the process of step S302, the information stored in the IC card 101 is transmitted to the reader / writer 102, and the reader / writer 102 determines a section where the boarding is possible with the designated seat ticket (IC card 101). The information indicating whether or not admission is permitted is transmitted to the IC card 101. In step S306, it is determined whether or not admission is possible based on information indicating whether or not admission is transmitted from the reader / writer 102.

  If it is determined in step S306 that admission is possible, the process proceeds to step S307. In step S307, the CPU 144 writes information such as an entrance flag ON and operation information in the data memory 145.

  Here, the admission flag is a flag indicating that the admission is made using the designated seat ticket. The operation information is the latest operation information at the time when the process of step S307 is performed.

  FIG. 13 is a diagram showing a display example of the display unit 147 at this time. In the figure, the display unit 147 displays “Tokyo-Osaka”, “10: 00-16: 00”, and “7th line A17 seat”. That is, at the time of entry, the information written in the process of step S304 described above is not updated and is displayed as it is.

  The display unit 147 displays “Normal operation”. This is information that is specified and displayed based on the latest operation information written in the process of step S307 described above and that a train that can be boarded by the designated seat ticket is operating as usual.

  FIG. 14 is a diagram illustrating another display example of the display unit 147 when the process of step S307 ends. In the figure, the display unit 147 displays “Balance: ¥ 12,345”. This is information that is displayed based on the data read from the data memory 145, specifying that the balance currently charged in the IC card is 12,345 yen.

  The display unit 147 displays “Normal operation”. This is information that is specified and displayed based on the latest operation information written in the process of step S307 described above and that a train that can be boarded by the designated seat ticket is operating as usual.

  When the processing of step S307 is completed, for example, the display screen as shown in FIG. 13 and the display screen as shown in FIG. 14 may be displayed alternately and continuously on the display unit 147. Good.

  On the other hand, if it is determined in step S306 that admission is not possible, the process proceeds to step S312 and a predetermined error process is executed.

  If it is determined in step S305 that the process type is ticket gate exit, the process proceeds to step S308.

  In step S308, the CPU 144 determines whether it is possible to leave. Specifically, for example, in the process of step S302, the information stored in the IC card 101 is transmitted to the reader / writer 102, and the reader / writer 102 can get on the designated seat ticket (IC card 101), the above-mentioned section The information indicating whether or not the entrance flag and the inspection flag (to be described later) are turned on is transmitted to the IC card 101. In step S308, it is determined whether or not it is possible to leave based on information indicating whether or not entry is possible transmitted from the reader / writer 102.

  If it is determined in step S308 that the exit is possible, the process proceeds to step S309. In step S309, the CPU 144 writes information such as history information and transfer information in the data memory 145 together with information (for example, a flag) for making the designated seat ticket used.

  Here, the transfer information is, for example, information on routes near the arrival station in the boarding section of the designated ticket.

  FIG. 15 is a diagram showing a display example of the display unit 147 at this time. In the figure, the display unit 147 displays “Balance: ¥ 12,345”. This is displayed as it is without updating the information written in the process of step S304 described above.

  The display unit 147 displays “Transfer guidance: xxxxxx...”. This is information in which the information on the route near the arrival station in the boarding section of the designated seat ticket is specified and displayed based on the transfer information written in the process of step S309 described above.

  The display screen as shown in FIG. 15 is meaningless even if it is displayed for a long time, so it is displayed temporarily (only for a predetermined time), and thereafter, simply “Balance: ¥ 12,345” is displayed on the display unit 147. May be displayed.

  On the other hand, if it is determined in step S308 that it is not possible to leave, the process proceeds to step S312 and a predetermined error process is executed.

  If it is determined in step S305 that the process type is ticket check, the process proceeds to step S310.

  In step S310, the CPU 144 determines whether or not the ticket has been legitimately checked (checking is OK). Specifically, for example, in step S302, the information stored in the IC card 101 is transmitted to the reader / writer 102 configured as a station ticket checking terminal or the like, and the reader / writer 102 receives the designated seat ticket ( It is checked whether the IC card 101) can be boarded, the seat number, the entrance flag is ON, and the like, and information indicating whether or not the ticket check is OK is transmitted to the IC card 101. In step S310, it is determined whether or not admission is possible based on information indicating whether or not admission is transmitted from the reader / writer 102.

  Alternatively, the reader / writer 102 may be incorporated in a seat in a train, for example, and when a user holding the IC card 101 is seated in the seat, the check processing is automatically executed.

  If it is determined in step S310 that the ticket check is OK, the process proceeds to step S311. In step S311, the CPU 144 writes information such as a ticket checking flag ON and arrival station information in the data memory 145.

  Here, the ticket check flag is a flag indicating that the ticket check has been made for the designated seat ticket. The arrival station information is, for example, weather information around the arrival station at the time when the process of step S307 is performed.

  FIG. 16 is a diagram showing a display example of the display unit 147 at this time. In the figure, the display unit 147 displays “To Osaka” and “Scheduled to arrive at 16:00”. That is, although the information written in the process of step S304 described above has not been updated, the departure station and departure time are not displayed at the time of entry (after the entry flag is turned on), and the arrival station Only the estimated time of arrival is displayed.

  The display unit 147 displays “Osaka: Fine”. This is displayed on the basis of the arrival station information written in the process of step S311 described above, indicating that the weather around the arrival station (Osaka Station) in the boarding section of the reserved seat ticket is clear. Information.

  FIG. 17 is a diagram illustrating another display example of the display unit 147 when the process of step S311 is completed. In the drawing, “7th line A17 seat” is displayed on the display unit 147, and “balance: ¥ 12,345” is displayed. This is information displayed by reading the data written in the process of step S304 described above from the data memory 145.

  When the processing of step S311 is completed, for example, a display screen as shown in FIG. 16 and a display screen as shown in FIG. Good.

  On the other hand, if it is determined in step S310 that the ticket check is not OK, the process proceeds to step S313, and a predetermined error process is executed.

  After the process of step S307, S309, S311, S312, or S313, the process proceeds to step S314, and the IC card 101 is reset.

  In this way, ticket gate entry, ticket gate exit, or ticket check processing is executed in the IC card 101 used as the designated seat ticket, and information based on the stored data is displayed on the display unit 147 according to the processing result.

  Next, an example in which the IC card 101 is used as a ticket for a play or concert performed in a theater or the like will be described. Here, for example, a user who is a spectator of a theater or a concert purchases a ticket by operating the PC connected to the Internet in advance and paying the price of the ticket from the prepaid balance of the IC card 101. It is assumed that the ticket obtained is stored as data in the IC card 101. When the IC card 101 is used as a ticket, the card type corresponding process 4 shown in FIG. 18 is executed in step S105 of FIG.

  Here, the details of the card type correspondence processing 4 will be described with reference to the flowchart of FIG.

  Since the processes of steps S341 and S342 are the same as the processes of steps S201 and S202 of FIG. 3, detailed description thereof is omitted.

  In step S343, the CPU 144 determines whether or not a process such as a transaction executed based on communication with the reader / writer 102 in step S302 is a ticketing process. Here, the ticketing is a process executed with the purchase of the ticket. If it is determined in step S343 that the ticket is issued, the process proceeds to step S344. In this case, the reader / writer 102 is incorporated in a PC connected to the Internet.

  In step S344, the CPU 144 writes information such as a name code, start date / time, performance place, seat number, updated balance, and guide information in the data memory 145.

  Here, the name code is, for example, a code for identifying the name of a theater or concert that can be viewed with the ticket, and the start date, performance location, and seat number are respectively the theater or concert that can be viewed with the ticket. The date and time of the performance, the venue, and the seat number reserved by the ticket. Information about the performance end time may be stored as necessary. The updated balance is a balance updated by subtracting the price of the ticket from the prepaid balance charged in the IC card 101, and the guidance information relates to, for example, a play or concert that can be played with the ticket. Information.

  FIG. 19 is a diagram showing a display example of the display unit 147 at this time. In the figure, the display unit 147 displays “XYZ play”. This is information that is specified and displayed based on the name code written in the process of step S344 described above that the name of the theater that can be played by the ticket is “XYZ play”.

  The display unit 147 displays “06/10/01 18:00”. This is displayed based on the start date and time information written in the process of step S344 described above, and the start date and time of the play that can be played with the ticket is identified as 1st October 2006 18:00. Information.

  Further, “ABC hole” is displayed on the display unit 147. This is information that is displayed based on the information on the performance place written in the process of step S344 described above, with the theater performance place that can be played by the ticket specified as an ABC hall.

  Further, “A17 seat” is displayed on the display unit 147. This is information displayed by specifying that the seat number reserved by the ticket is “A17” based on the seat number information written in the process of step S344 described above.

  After the process of step S344, or when it is determined in step S343 that the process is not ticketing, the process proceeds to step S345.

  In step S345, the CPU 144 determines the type of processing such as a transaction to be executed based on communication with the reader / writer 102 in step S342. In this case, since the IC card 101 is used as a ticket, it is assumed that there are three types (types) of processing such as entry, seating, or exit as processing types. Here, the reader / writer 102 is incorporated in an entrance gate, an exit gate, or a seat.

  Here, for example, the entry is a process that is performed when a user holding the IC card 101 passes through a gate incorporating a reader / writer 102 installed at an entrance of a performance place or the like. In addition, the seating is a process that is performed when, for example, a user who has the IC card 101 sits in a predetermined seat inside the performance place and in which the reader / writer 102 is incorporated. Further, the exit is a process performed when, for example, a user who has the IC card 101 passes through a gate in which a reader / writer 102 installed at an exit of a performance place or the like is incorporated.

  If it is determined in step S345 that the process type is entrance, the process proceeds to step S346.

  In step S346, the CPU 144 determines whether or not entry is possible. Specifically, for example, in step S302, the information stored in the IC card 101 is transmitted to the reader / writer 102, and the reader / writer 102 displays the name code of the theater that can be played with the ticket (IC card 101). The information indicating whether or not admission is permitted is transmitted to the IC card 101. In step S346, it is determined whether or not admission is possible based on information indicating whether or not admission is transmitted from the reader / writer 102.

  If it is determined in step S346 that admission is possible, the process proceeds to step S347. In step S347, the CPU 144 writes information such as an entrance flag ON and a seat image in the data memory 145.

  Here, the entrance flag is a flag indicating that the entrance has been made using the ticket. The seat image is data such as an image for informing the user of the position of the seat reserved by the ticket.

  FIG. 20 is a diagram illustrating a display example of the display unit 147 at this time. In the drawing, “A17 seat” is displayed on the display unit 147, and “18:00 performance” is displayed. In these, the information written in the process of step S344 described above is displayed as it is without being updated.

  The display unit 147 displays a seat image as an image based on the seat image data written in step S347 described above. If it is difficult to send and receive image data between the reader / writer 102 and the IC card 101, or if it is difficult to display a seat image on the display unit 147 of the IC card 101, the seat Instead of the image, for example, character information indicating the position of the seat such as “Oth row from the front, xth from the left” may be displayed.

  On the other hand, if it is determined in step S346 that entry is not possible, the process proceeds to step S352, and a predetermined error process is executed.

  If it is determined in step S345 that the process type is seated, the process proceeds to step S348.

  In step S348, the CPU 144 determines whether seating is possible. Specifically, for example, in the process of step S342, the information stored in the IC card 101 is transmitted to the reader / writer 102, and the seat number reserved with the ticket (IC card 101) in the reader / writer 102 is the seat number. The information indicating whether or not seating is possible is transmitted to the IC card 101. In step S348, it is determined whether or not admission is possible based on information indicating whether or not admission is transmitted from the reader / writer 102.

  If it is determined in step S348 that the exit is possible, the process proceeds to step S349. In step S349, the CPU 144 writes information such as the seating flag ON in the data memory 145. Here, the seating flag is a flag indicating that the user has seated in the seat reserved with the ticket.

  FIG. 21 is a diagram showing a display example of the display unit 147 at this time. In the figure, the display unit 147 displays “XYZ play”, “21:00 end”, and “A17 seat”. That is, the information written in the process of step S344 described above has not been updated, but at the time of entry (after the admission flag is turned on), the start time and the performance place are not displayed, and the name of the play In addition, an end time and a seat number are displayed.

  The display unit 147 displays “next schedule: xxx”. This is information that is specified and displayed based on the guidance information written in the process of step S344 described above, such as the name of the theater to be performed next time at the performance location (in this case, ABC Hall). .

  On the other hand, if it is determined in step S348 that seating is not possible, the process proceeds to step S352, and a predetermined error process is executed.

  If it is determined in step S345 that the process type is exit, the process proceeds to step S350.

  In step S350, the CPU 144 determines whether it is possible to leave. Specifically, for example, in the process of step S342, information stored in the IC card 101 is transmitted to the reader / writer 102, and the reader / writer 102 sets the above-described entrance flag and seating flag of the ticket (IC card 101). It is checked whether it is ON or the like, and information indicating whether or not to leave is transmitted to the IC card 101. In step S350, it is determined whether or not leaving can be performed based on information indicating whether or not leaving can be transmitted from the reader / writer 102.

  If it is determined in step S350 that the exit is possible, the process proceeds to step S351. In step S351, the CPU 144 writes information such as history information and guidance information in the data memory 145 together with information (for example, a flag) for treating the ticket as used.

  Here, the guidance information is, for example, detailed information about the theater to be performed next time at the performance place (in this case, ABC Hall).

  FIG. 22 is a diagram showing a display example of the display unit 147 at this time. In the drawing, “next schedule: (detailed information)” is displayed on the display unit 147. This is information in which detailed information about the play to be performed next time is specified and displayed based on the guidance information written in the process of step S351 described above. The actual detailed information is, for example, information such as the performer of the theater to be performed next time and the start date and time at the performance place.

  Also, the display screen as shown in FIG. 22 is meaningless even if displayed for a long time, so it is displayed temporarily (only for a predetermined time), and then the prepaid balance and the like are displayed on the display unit 147. You may make it do.

  On the other hand, if it is determined in step S350 that it is not possible to leave, the process proceeds to step S353, and a predetermined error process is executed.

  After the process of step S347, S349, S351, S352, or S353, the process proceeds to step S354, and the IC card 101 is reset.

  In this manner, the entry, exit, or seating process is performed on the IC card 101 used as a ticket, and information based on the data stored with the processing result is displayed on the display unit 147.

  Alternatively, the IC card 101 may be used as a ticket used in an amusement park or the like. In such a case, the display unit 147 appropriately displays, for example, a so-called stamp rally, a map or park map to which information such as rides and attractions experienced by the user, a mark of a use facility, and the like are added. Become.

  In the above, various examples in which data stored in the IC card 101 is read out and displayed on the display unit 147 according to processing, usage, and the like have been described. However, prepaid balance information among the displayed information. Is particularly important information. For example, in the case where the IC card 101 is used as a ticket, it is inconvenient if the balance is not known when it is desired to purchase with a prepaid card such as food and drink after admission. In addition, for example, if the IC card 101 is used to accidentally purchase more than the balance, an error occurs due to insufficient balance, and as a result, processing takes longer than paying with cash. The convenience of the IC card 101 may be lost.

  However, in the small IC card 101, it is considered difficult to make the display unit 147 sufficiently large.

  Therefore, for example, when an area for displaying the balance cannot be secured on the display unit 147, the balance may be switched to a display using a bar instead of a number. That is, the display switching unit 146 determines whether or not an area for displaying the balance can be secured based on the amount of information to be displayed on the display unit 147. What is necessary is just to make it display a balance by the bar display on the screen lower part of the part 147, etc.

  FIG. 23 is a diagram illustrating an example of a display screen of the display unit 147 when the balance is displayed as a bar. This figure shows an example in which the balance is further displayed on the display screen of FIG. 13 described above. The same information as in the case of FIG. 13 is displayed, and the balance is displayed as a bar 301 on the lower side in the figure. ing. In other words, the bar 301 represents the balance corresponding to the position on the scale described below, and in the figure, the balance charged to the IC card 101 is “12,345 yen”. A display example of the bar 301 is shown. The scale on the lower side of the bar 301 can be displayed with the scale unit, interval, etc. changed according to the amount of the balance.

  By doing so, the limited area of the display unit 147 can be used effectively.

  Note that the steps of executing the series of processes described above in this specification are performed in parallel or individually even if they are not necessarily processed in time series, as well as processes performed in time series in the order described. The processing to be performed is also included.
