  Further, the processing unit 112 can start the service process based on the determination result of the transmission completion determination unit 110 by reading the information of the determination result held by the transmission completion determination unit 110. For example, the processing unit 112 starts a service process when the determination result information of each update target data stored in the storage unit 104 is “01” (not transmission target) or “11” (transmission complete). Can be, but is not limited to the above.

Here, the communication between the reader / writer 100 (information processing apparatus) and the IC chip mounting apparatus 150 shown in FIG. 4 is performed using, for example, a 13.56 MHz carrier wave.

  When communication is started between the reader / writer 100 and the IC chip mounting apparatus 150 (S100), the reader / writer 100 requests the IC chip mounting apparatus 150 to obtain a service code (S102). Here, the start of communication in step S100 can be performed, for example, when the reader / writer 100 continues to transmit a carrier wave to perform polling constantly or periodically and detect the IC chip mounting device 150. it can. Further, the target required in the process of step S102 is not limited to the service code, but is information for identifying the service and IC chip mounting device 150 corresponding to the IC chip mounting device 150, such as a system code and an IC chip ID.

  The reader / writer 100 that has received the service code transmitted in step S104 can specify the service to which the IC chip mounting apparatus 150 corresponds based on the received service code. Then, the reader / writer 100 transmits a rewrite process start request (update process start request) for transmitting the start of the software rewrite process to the IC chip mounting apparatus 150 (S106).

  The IC chip mounting apparatus 150 that has received the rewrite processing start request transmitted in step S106 makes a response to the request (S108). Here, the response in step S108 can be, for example, 1-bit data indicating whether or not the rewriting process is ready (for example, “0” is not ready and “1” is ready). It is not restricted to the above.

  The reader / writer 100 that has received the response transmitted in step S108 starts the rewriting process and transmits a version number acquisition request (request for information on the version of the update target data) (S110).

Here, the processing result transmitted in step S120 includes, for example, predetermined bit data for specifying each update target data and 1-bit data indicating whether rewriting has succeeded (for example, “0” is rewriting failure). , “1” is successful rewriting), and can be data for each update target data for which data writing processing has been performed, but is not limited thereto.

  The reader / writer 100 that has received the processing result transmitted in step S120 determines transmission completion for each update target data stored in the storage unit 104 (S122; transmission completion determination processing). Here, for example, the reader / writer 100 can exclude update target data stored in the storage unit 104 but not stored in the IC chip mounting device 150 from the determination target in step S122.

  If there is update target data for which it has been determined in step S122 that the processing has not been completed, the reader / writer 100 again displays the difference block information and the difference data corresponding to the update target data for which it has been determined that the processing has not been completed. Transmit (S116).

Here, the response in step S126 can be, for example, 1-bit data indicating whether or not the rewriting process is finished (for example, “0” is not finished and “1” is finished). It is not restricted to the above.

  The reader / writer 100 that has received the response transmitted in step S126 ends the rewriting process and performs data processing (service processing) with the IC chip mounting apparatus 150 (S128). When the data processing in step S128 is completed, the reader / writer 100 ends communication with the IC chip mounting device 150 (S130).

When the reader / writer 100 receives the service code transmitted in step S204, the reader / writer 100 can specify the service to which the IC chip mounting apparatus 150 corresponds. Then, as in the first example shown in FIG. 4, the reader / writer 100 transmits a rewrite process start request (update process start request) to notify the IC chip mounting device 150 of the start of the software rewrite process ( S206). Then, the IC chip mounting apparatus 150 that has received the rewrite processing start request transmitted in step S206 makes a response to the request (S208).

Then, the specified update target data is rewritten using the difference data (S218; data writing process). Then, when the data writing process in step S218 is performed, the IC chip mounting apparatus 150 transmits the processing result (S220).

  The reader / writer 100 that has received the processing result transmitted in step S220 determines transmission completion for each update target data stored in the storage unit 104, as in the first example shown in FIG. S222: transmission completion determination process). If there is update target data for which it has been determined in step S222 that the processing has not been completed, the reader / writer 100 again displays the difference block information and the difference data corresponding to the update target data for which it has been determined that the processing has not been completed. Transmit (S216).

  If it is determined in step S222 that the processing has been completed, the reader / writer 100 rewrites to notify the IC chip mounting device 150 of the end of the software rewrite processing, as in the first example shown in FIG. A processing end request (update processing end request) is transmitted (S224). Then, the IC chip mounting apparatus 150 that has received the rewrite processing end request transmitted in step S224 makes a response to the request in the same manner as in the first example shown in FIG. 4 (S226).

  The reader / writer 100 that has received the response transmitted in step S226 ends the rewriting process and performs data processing (service processing) with the IC chip mounting apparatus 150 (S228). When the data processing in step S228 is completed, the reader / writer 100 ends communication with the IC chip mounting device 150 (S230).

  As shown in FIG. 5, the second example of the software update control method according to the embodiment of the present invention uses the update target data stored in the IC chip mounting apparatus 150 using the block information of the update target data, the reader / The difference from the update target data stored in the storage unit 104 of the writer 100 is different from the first example of the software update control method according to the embodiment of the present invention shown in FIG. However, since the difference can be determined even if the block information of the update target data is used, the reader / writer 100 using the second example of the software update control method according to the embodiment of the present invention is shown in FIG.

They have similar functions and can have the same configuration.

  The communication target determination unit 202 defines the device type for the IC card 250 when there is a response from the IC card 250 to polling (that is, when the IC card 250 as a communication target is detected).
