Next, a configuration example of the IC sheet 60 will be described.
Since the IC sheets 60a and 60b have the same configuration, they will be described as the IC sheet 60.

FIG. 2 is a block diagram schematically showing a configuration example of the IC sheet 60 according to the embodiment. As shown in FIG. 2, the IC sheet 60 has a card-shaped main body S made of paper, plastic, vinyl, or the like. The IC sheet 60 has an IC module M built in the main body S. The IC module M is integrally formed with the IC chip C and the communication unit 25 connected to each other, and is embedded in the main body S of the IC sheet 60.

As shown in FIG. 2, the IC sheet 60 includes an IC module M and the like. The IC module M includes an IC chip C, a communication unit 25, and the like. The IC chip C includes a processor 21, a ROM 22, a RAM 23, an NVM 24, and the like. The processor 21 connects to the ROM 22, the RAM 23, the NVM 24, and the communication unit 25 via a data bus or the like.

The IC sheet 60 may have a configuration as required in addition to the configuration shown in FIG. 3, or a specific configuration may be excluded from the IC sheet 60.

The processor 21 functions as a control unit that controls the entire IC sheet 60. The processor 21 performs various processes based on the control program and control data stored in the ROM 22 or the NVM 24. For example, the processor 21 executes various processes according to the operation control of the IC sheet 60 or the operation mode of the IC sheet 60 by executing the program stored in the ROM 22.

It should be noted that some of the various functions realized by the processor 21 executing the program may be realized by the hardware circuit. In this case, the processor 21 controls the functions performed by the hardware circuits.

The ROM 22 is a non-volatile memory that stores a control program, control data, and the like in advance. The ROM 22 is incorporated in the IC sheet 60 in a state where the control program, control data, and the like are stored in the manufacturing stage. That is, the control program and control data stored in the ROM 22 are incorporated in advance according to the specifications of the IC sheet 60 and the like.

The RAM 23 is a volatile memory. The RAM 23 temporarily stores data and the like being processed by the processor 21. For example, the RAM 23 functions as a calculation buffer, a reception buffer, and a transmission buffer.

The NVM 24 is composed of, for example, a non-volatile memory such as a flash ROM capable of writing and rewriting data. The NVM 24 stores a control program, an application, and various data according to the operational use of the IC sheet 60. For example, in NVM24, a program file, a data file, and the like are created. A control program and various data are written in each created file.

The communication unit 25 is an interface for transmitting and receiving data to and from the reader / writer 20. That is, the communication unit 25 is an interface for transmitting and receiving data to and from the information processing device 10.

When the IC sheet 60 is a contact type IC sheet, the communication unit 25 is composed of a communication control unit and a contact unit for physically and electrically contacting the reader / writer 20 to transmit and receive signals. For example, the IC sheet 60 is activated by receiving an operating power supply and an operating clock from the reader / writer 20 via the contact portion.

When the IC sheet 60 is a non-contact type IC sheet, the communication unit 25 is composed of a communication control unit such as a modulation / demodulation circuit for performing wireless communication with the reader / writer 20 and an antenna. For example, the IC sheet 60 receives radio waves from the reader / writer 20 via an antenna, a modulation / demodulation circuit, and the like. The IC sheet 60 is activated by generating an operating power supply and an operating clock from the radio wave by a power supply unit (not shown).

Next, the functions realized by the IC module M will be described. The function realized by the IC module M is realized by the processor 21 executing a program stored in the ROM 22 or the NVM 24 or the like.

The processor 21 has a function of storing predetermined data according to a command from the reader / writer 20.

The processor 21 receives a write command for writing predetermined data from the reader / writer 20 through the communication unit 25. For example, a write command is a command for writing a key related to cryptographic processing.

The processor 21 stores the data in the NVM 24 or the like according to the write command. When the data is stored in the NVM 24 or the like, the processor 21 transmits a response indicating that the writing is completed to the reader / writer 20 through the communication unit 25.

Further, when the data storage fails, the processor 21 transmits a response indicating that the writing has failed to the reader / writer 20 through the communication unit 25.

Next, the functions realized by the PLC 30 will be described. The functions realized by the PLC 30 are realized by the internal processor executing a program stored in an internal memory or the like.

First, the PLC 30 has a function of transporting the IC sheet 60 before writing data to a predetermined position by using the transport unit 40.

The PLC 30 conveys the mount 50 that supports the IC sheet 60 before writing data to a position where the IC module M and the reader / writer 20 can communicate with each other. For example, the PLC 30 takes out the mount 50 from the container that stores the mount 50 and conveys it. When the PLC 30 detects that the mount 50 has reached the position through a predetermined sensor, the PLC 30 stops the mount 50.
For example, the PLC 30 transports the mount 50 by supplying electric power to the motor of the transport unit 40.

Further, the PLC 30 has a function of transmitting a signal (processing execution signal) for starting the data writing process to the information processing device 10.

When the mount 50 supporting the IC sheet 60 before writing data is conveyed to a position where the IC module M and the reader / writer 20 can communicate with each other, the PLC 30 transmits a processing execution signal to the information processing device 10.

Further, the PLC 30 has a function of receiving a signal (completion signal) indicating that the data writing is completed or a signal (error signal) indicating that the data writing has failed from the information processing device 10.

When the PLC 30 transmits the processing execution signal to the information processing device 10, the PLC 30 receives a completion signal or an error signal from the information processing device 10.

Further, when the PLC 30 does not receive the completion signal or the error signal even after a predetermined time (timeout time) has elapsed since the processing execution signal is transmitted, the PLC30 informs the signal (inquiry signal) asking whether to extend the timeout time. It is transmitted to the processing device 10.

For example, when the PLC 30 transmits a processing execution signal, the PLC 30 starts an internal timer. The PLC 30 determines whether the time clocked by the timer has reached the timeout time. When it is determined that the time measured by the timer has reached the timeout time, the PLC 30 transmits an inquiry signal to the information processing device 10.

The time-out time is based on the time (writing time) required for the data writing system 1 to write data to the IC sheet 60. For example, the time-out time is shorter than the time required to write data to a predetermined IC sheet 60 in the assumed IC sheet 60. For example, some of the assumed IC sheets 60 have a relatively long writing time and some have a relatively short writing time, but the timeout time is the IC sheet having the longest writing time. It is a time shorter than the time required to write data to 60.

Further, the time-out time may be the time required to write data to the IC sheet 60, which has the fastest writing time among the assumed IC sheets 60.
The method for determining the timeout time is not limited to a specific method.

For example, the timeout time is about several seconds (for example, 4 to 6 seconds).

Further, the PLC 30 has a function of extending the timeout time when receiving a signal (extension request signal) requesting the extension of the timeout time for the inquiry from the information processing apparatus.

Upon receiving the extension request signal, the PLC 30 extends the timeout time by a predetermined time (for example, about 0.1 second to 1 second).

The PLC 30 has a function of discarding the IC sheet 60 when the extension request signal is not received.

When the PLC 30 does not receive the extension request signal from the information processing apparatus 10 even after waiting for a predetermined time after transmitting the inquiry signal, the PLC 30 discards the IC sheet 60 by using the transport unit 40. For example, the PLC 30 uses the transport unit 40 to transport the mount 50 of the IC sheet 60 to a predetermined disposal location.

Further, when the PLC 30 receives a signal from the information processing device 10 indicating that the timeout time is not extended with respect to the inquiry signal, the IC sheet 60 may be discarded.

Further, the PLC 30 may discard the IC sheet 60 when an error signal is received from the information processing device 10 within the timeout time. In this case, the PLC 30 may discard the IC sheet 60 after the timeout time has elapsed from the transmission of the processing execution signal.

Further, the PLC 30 has a function of transporting the IC sheet 60 to a predetermined place by using the transport unit when the completion signal is received from the information processing device 10 within the timeout time.

For example, when the PLC 30 receives the completion signal, the PLC 30 transports the IC sheet 60 to a predetermined place after the timeout time has elapsed. For example, the PLC 30 conveys the mount 50 that supports the IC sheet 60 to a predetermined container that stores the IC sheet 60 for which data has been written. Further, the PLC 30 may discharge the mount 50 supporting the IC sheet 60 to the outside of the data writing system 1.

Further, when the PLC 30 receives the completion signal, the IC sheet 60 may be conveyed to a predetermined place even if the timeout time does not elapse.

Next, the functions realized by the information processing apparatus 10 will be described. The function realized by the information processing device 10 is realized by the processor 11 executing a program stored in the ROM 12 or the NVM 14.

First, the processor 11 has a function (writing processing function) of writing predetermined data to the IC module M through the reader / writer 20.

The processor 11 receives the processing execution signal through the PLC interface 16. Upon receiving the processing execution signal, the processor 11 writes predetermined data to the IC module M through the reader / writer 20.

For example, the processor 11 transmits a write command for writing predetermined data to the IC module Ma through the reader / writer 20a. Here, the IC module Ma stores predetermined data according to a write command, and transmits a response indicating that the writing is completed to the reader / writer 20a.

The processor 11 receives the response through the reader / writer 20a. Upon receiving the response, the processor 11 transmits a write command for writing predetermined data to the IC module Mb through the reader / writer 20b. Here, the IC module Mb stores predetermined data according to a write command, and transmits a response indicating that the writing is completed to the reader / writer 20b.
The processor 11 receives the response through the reader / writer 20b.

Upon receiving the response, the processor 11 transmits a completion signal to the PLC 30 through the PLC interface 16.

When the processor 11 receives the response indicating that the writing has failed from the IC module Ma or Mb, the processor 11 transmits an error signal to the PLC 30 through the PLC interface 16. When the processor 11 receives a response indicating that the writing has failed from the IC module Ma or Mb, the processor 11 may transmit the writing command to the IC module Ma or Mb again. The processor 11 may transmit an error signal to the PLC 30 when it receives a response indicating that writing has failed a predetermined number of times from the IC module Ma or Mb.

Further, the processor 11 may generate predetermined data, or may acquire it from the NVM 14 or an external device. For example, the predetermined data is a key for cryptographic processing.

Further, the processor 11 has a function of transmitting an extension request signal in response to the inquiry signal from the PLC 30.

The processor 11 receives an inquiry signal from the PLC 30 through the PLC interface 16. Upon receiving the inquiry signal, the processor 11 determines whether the number of times the extension request signal is transmitted to the PLC is equal to or less than a predetermined threshold value (for example, 2). To do.

When it is determined that the number of times the extension request signal is transmitted to the PLC is equal to or less than a predetermined threshold value, the processor 11 transmits the extension request signal to the PLC 30 through the PLC interface 16.

If it is determined that the number of times the extension request signal is transmitted to the PLC is not equal to or less than a predetermined threshold value, the processor 11 may transmit a signal to the PLC 30 indicating that the timeout time is not extended. Further, in this case, the processor 11 does not have to respond to the inquiry signal.

Further, if there is an IC sheet 60 before writing the data, the data writing system 1 continuously writes the data to the IC sheet 60.

Next, an operation example of the PLC 30 will be described.
FIG. 5 is a flowchart for explaining an operation example of the PLC 30.

First, the PLC 30 requests the information processing device 10 for an initial response, and receives the initial response from the information processing device 10 (S41). Upon receiving the initial response, the PLC 30 uses the transport unit 40 to transport the IC sheet 60 before writing data to a predetermined position (S42).

When the IC sheet 60 is conveyed, the PLC 30 transmits a processing execution signal to the information processing device 10 (S43). Upon receiving the processing execution signal, the PLC 30 determines whether or not a response has been received from the information processing device 10 (S44).

When it is determined that the response has not been received from the information processing apparatus 10 (S44, NO), the PLC 30 determines whether the timeout time has elapsed since the processing execution signal was transmitted (S45). If it is determined that the timeout time has not elapsed since the processing execution signal was transmitted (S45, NO), the PLC 30 returns to S44.

When it is determined that the data writing operation is finished (S52, YES), the PLC 30 ends the operation.

Next, an operation example of the information processing device 10 will be described.
FIG. 6 is a flowchart for explaining an operation example of the information processing apparatus 10.

First, the processor 11 of the information processing device 10 transmits an initial response to the PLC 30 through the PLC interface 16 (S61). As described above, when the processor 11 receives the request for the initial response from the PLC 30, the processor 11 requests the reader / writer 20 for the initial response. When the processor 11 receives the initial response from the reader / writer 20, the processor 11 transmits the initial response to the PLC 30.

When the initial response is transmitted to the PLC 30, the processor 11 resets (n = 0) n for counting the number of extensions (S62). When n for counting the number of extensions is reset, the processor 11 determines whether or not the processing execution signal has been received from the PLC 30 through the PLC interface 16 (S63).

If it is determined that the processing execution signal has not been received from the PLC 30 (S63, NO), the processor 11 returns to S63.

When it is determined that the processing execution signal has been received from the PLC 30 (S63, YES), the processor 11 starts the writing process to the IC module M through the reader / writer 20 (S64).

When the writing process is started, the processor 11 determines whether the writing process is completed (S65). When it is determined that the writing process is not completed (S65, NO), the processor 11 determines whether the inquiry signal has been received from the PLC 30 through the PLC interface 16 (S66).

When it is determined that the inquiry signal has been received from the PLC 30 (S66, YES), the processor 11 determines whether n is 2 or less (S67). If it is determined that n is 2 or less (S67, YES), the processor 11 transmits an extension request signal to the PLC 30 through the PLC interface 16 (S68).

When the extension request signal is transmitted to the PLC 30, the processor 11 increments n (S69).
When it is determined that the inquiry signal has not been received from the PLC 30 (S66, NO) or when n is incremented (S69), the processor 11 returns to S65.

When it is determined that the writing process is completed (S65, NO), the processor 11 determines whether or not a response indicating that the writing is completed has been received through the reader / writer 20 (S70).

When it is determined that n is not 2 or less (S67, NO), or when it is determined that the response indicating that the writing is completed has not been received (S70, NO), the processor 11 makes an error through the PLC interface 16. The signal is transmitted to the PLC 30 (S71).

When it is determined that the response indicating that the writing is completed is received (S70, YES), the processor 11 transmits the completion signal to the PLC 30 through the PLC interface 16 (S71).

When the error signal is transmitted to the PLC 30 (S71) or the completion signal is transmitted to the PLC 30 (S72), the processor 11 determines whether to end the data writing operation (S73).

If it is determined that the data writing operation is not completed (S73, NO), the processor 11 returns to S62.
When it is determined that the data writing operation is finished (S73, YES), the processor 11 ends the operation.

The reader / writer 20 may be composed of three or more reader / writers. In this case, the mount 50 may include three or more IC sheets.
Further, the reader / writer 20 may be composed of one reader / writer. In this case, the mount 50 may include one IC sheet.

Further, the processor 11 may realize the function of the PLC 30. That is, the processor 11 may be able to control ON / OFF of the operation of the transport means, or may be able to determine whether or not the IC module M has been transported to a predetermined position by referring to the signal from the sensor. .. The reader / writer 20 may be integrally formed with the information processing device 10.
Further, the data writing system 1 may write data to the IC module M included in the IC card.

When the data writing is completed, the information processing apparatus configured as described above performs the writing process on the next IC sheet when the timeout time elapses. Further, when the data writing is not completed within the timeout time, the information processing apparatus extends the timeout time and completes the data writing. Further, the information processing apparatus described in the above embodiment does not process based on the sheet having a slow write processing time, but determines whether or not the writing is completed in a time shorter than the time required for the writing process (default). It is characterized in that it is set as the reference time).

As a result, when the writing is completed quickly, the sheet can be transported to the next step without waiting for the conventional time, so that the takt time is shortened. In addition, even if the writing processing time becomes long, the yield of the IC sheet can be improved by extending it each time and not making an error easily, and the sheet that can be processed quickly and the sheet that cannot be processed quickly. The total tact time including the time of use can be kept within a desired range. In other words, the information processing apparatus in this embodiment can write data to the IC sheet, which takes a long time to write, without discarding it, while maintaining the overall takt time.
