- the revision of the program data stored in is “Rev.a”
- an initialization command is issued.
- step ST4 the download control unit 21 issues an initialization command to the card reader 30.
- the download control unit 21 determines whether the card reader 30 is in a download mode in which the program data 231 can be downloaded from the response of the card reader 30 to the initialization command (step ST5). ). If the card reader 30 is not in the download mode in step ST5 (if “No” in step ST5), the download control unit 21 issues a mode switching command to the card reader 30 (step ST6). After changing the card reader 30 to the download mode, the process returns to step ST4.
- step ST5 if the card reader 30 is in the download mode in step ST5 (if “Yes” in step ST5), the download control unit 21 reads the second and subsequent lines of the download file 23 line by line (step ST7) It is determined whether or not the read one line is the last line (EOF235) (step ST8).
- the download control unit 21 uses the read line 23 of the read download file 23 as a command to the card reader 30. Issue. For example, if the read one line is the second line of the download file 23, an erase command 233 is issued to the card reader 30. If the read line is the third line or later of the download file 23, the download command 234 is issued to the card reader 30 together with the shaped program data 231.
- the download control unit 21 determines whether or not the command has been normally executed based on the response of the card reader 30 (step ST10). If the response of the card reader 30 is a normal response (in the case of “Yes” in step ST10), the process returns to step ST7, and the next line of the download file 23 is read. On the other hand, if the response of the card reader 30 is an abnormal response (in the case of “No” in step ST10), the download control unit 21 determines that the download of the program data 231 has failed and ends the download process. In this case, the download system 10 may go down (the operation of the download system 10 stops).
- step ST8 when one line read from the download file 23 is the last line (in the case of “Yes” in step ST8), the download of the program data 231 is normally completed.
- step ST3 if the revision of the program data 231 stored in the host device 20 matches the revision of the program data stored in the firmware storage unit 311 (A, B) (step ST3).
- the download control unit 21 determines that the download of the program data 231 is unnecessary and ends the download process.
- the download control unit 21 ends the download process.

Even in this case, the second card reader 30B performs the same processing as that of a normal card reader (for example, described in Patent Document 1 described above) when downloading the firmware.
- a normal card reader for example, described in Patent Document 1 described above
- the card reader control unit 31B executes the erase command 233 based on the erase command 233 issued in step ST9. . Specifically, the rewrite control unit 312B erases the designated area in the firmware storage unit 311B. More specifically, the rewrite control unit 312B erases the program data in the firmware storage unit 311B corresponding to the program data 231. Further, the card reader control unit 31B returns a normal response to the download control unit 21 that the erase command 233 has been executed normally.
- the card reader control unit 31B executes the download command 234 based on the download command 234 issued in step ST9. Specifically, the rewrite control unit 312B stores (stores) the program data 231 transmitted from the host device 20 in a designated area in the firmware storage unit 311B. That is, the rewrite control unit 312B writes the program data 231 sent from the host device 20 to the firmware storage unit 311B. Further, the rewrite control unit 312B returns a normal response to the download control unit 21 that the download command 234 has been normally executed.

- the rewrite control unit 312A does not execute the erase command 233 in the second row, and returns a normal response indicating that the erase command 233 has been normally executed to the download control unit 21 (step ST22). That is, in step ST22, the rewrite control unit 312A returns a normal response that the erase command 233 has been normally executed to the download control unit 21 without deleting the program data stored in the firmware storage unit 311A.
- the rewrite control unit 312A receives the third line of the download file 23 issued in step ST9, that is, the download command 234 and the program data 231 (step ST23).
- the rewrite control unit 312A determines whether or not the rewrite permission data 236 is described in the program data 231 on the third line (step ST24). That is, in step ST24, the rewrite control unit 312A determines whether or not the program data 231 stored in the host device 20 is the program data 231 corresponding to the first card reader 30A.
- the card reader The control unit 31A and the rewrite control unit 312A perform the following processing. That is, when the rewrite permission data 236 is included in the download file 23A (in the case of “Yes” in step ST24), the rewrite control unit 312A of the card reader control unit 31A is an identification information storage unit that is a non-volatile memory. The storage area of the identification information (identification ID) of 32A is erased (step ST25).
- the card reader control unit 31A or the rewrite control unit 312A is configured to delete when the identification information (identification ID) is actually stored in the identification information storage unit 32A, or unconditionally.
- Various modes such as a configuration in which the storage area of the identification information in the identification information storage unit 32A is erased are possible.
- the rewrite control unit 312A receives the second and third line commands of the download file 23A, that is, the erase command 233 and the download command 234. Execute. Then, the rewrite control unit 312A returns a normal response that the download command 234 has been normally executed to the download control unit 21 (step ST26). Specifically, in step ST26, the rewrite control unit 312A erases the program data stored in the firmware storage unit 311A, and the program data 231 sent from the host device 20 is stored in the firmware storage unit 311A. Is stored (stored) in the designated area, and a normal response is returned to the download control unit 21.

- the rewrite control unit 312A sequentially receives the fourth and subsequent lines of the download file 23A (step ST27), and sequentially executes the download command 234 of the received line (step ST28). That is, the rewrite control unit 312A stores (stores) the program data 231 sent from the higher-level device 20 in a specified area in the firmware storage unit 311A, and the download command 234 is normally executed. A response is returned to the download control unit 21 (step ST28).
- the card reader The control unit 31A and the rewrite control unit 312A perform the following processing. That is, when the rewrite permission data 236 is not included in the download file 23B (in the case of “No” in step ST24), the rewrite control unit 312A performs the command on the third line of the download file 23B, that is, the download command 234. Is returned to the download control unit 21 as a normal response indicating that the download command 234 has been executed normally (step ST29). Specifically, in step ST29, the rewrite control unit 312A returns a normal response to the download control unit 21 without storing (storing) the program data 231 sent from the host device 20 in the firmware storage unit 311A.
- the rewrite control unit 312A sequentially receives the fourth and subsequent lines of the download file 23B (step ST30).
- the rewrite control unit 312A determines whether the received download file 23B has the identification information 237 (is included) (step ST31).
- the rewrite control unit 312A sets the identification information (identification ID) 237 from the received program data 231. Extracted and acquired (step ST32), and temporarily stored in an internal memory or register (step ST33).
- the identification information 237 of the download file 23B acquired and held here is identification information of the download file 23B treated as invalid for the first card reader 30A.
- step ST33 After the process of step ST33 or when the identification information 237 is not included in the download file 23B (“No” in step ST31), the rewrite control unit 312A does not execute the download command 234 for the received line. Then, a pseudo rewrite process is performed, and a normal response (pseudo response) that the download command 234 has been normally executed is returned to the download control unit 21 (step ST34).
- the rewrite control unit 312A returns the normal response (pseudo response) that the download command 234 is normally executed to the download control unit 21 by performing the pseudo rewrite process up to the last line of the download file 23B in step ST34. Then, the invalid identification information 237 temporarily stored in step ST33 is stored (stored) in the identification information storage unit 32A (step ST35).

In other words, the rewrite control unit 312A determines whether or not rewrite collation can be obtained in step ST42.
- step ST42 If the download file 23A is stored in the host device 20 and rewriting verification can be obtained in step ST42 (“Yes” in step ST42), the card reader control unit 31A and the rewriting control unit 312A perform rewriting verification. A normal response indicating that it has been taken is returned to the download control unit 21 (step ST43). Then, the card reader control unit 31A and the rewrite control unit 312A perform the following process as the rewrite collation is taken and a normal response is returned. That is, the rewrite control unit 312A of the card reader control unit 31A erases the storage area for the identification information (identification ID) of the identification information storage unit 32A, which is a nonvolatile memory (step ST44).

- the rewrite control unit 312A sequentially receives the fifth and subsequent lines of the download file 23A (step ST45), and sequentially executes the download command 234 of the received line (step ST46). That is, the rewrite control unit 312A stores (stores) the program data 231 sent from the higher-level device 20 in a specified area in the firmware storage unit 311A, and the download command 234 is normally executed. A response is returned to the download control unit 21 (step ST46).
- the rewriting control unit 312A performs the following process.
- the rewrite control unit 312A determines whether the rewrite permission data attached to the rewrite collation command 238 is the rewrite permission data attached to the rewrite collation command 238 of the download file 23B, or a download file such as a card reader of a different model. It is determined whether the data is the rewrite permission data attached to the rewrite collation command (step ST47). That is, in step ST47, the rewrite control unit 312A determines whether the program data stored in the host device 20 corresponds to the old second card reader 30B, or corresponds to a card reader of a different model. It is judged whether it is.
- step ST47 If the program data stored in the host device 20 corresponds to the second card reader 30B in step ST47, that is, if the download file 23B is stored in the host device 20 (“Yes” in step ST47). In this case, the rewrite control unit 312A returns a normal response to the download control unit 21 that the rewrite collation is obtained even though the rewrite collation is not obtained (step ST48). Thereafter, the rewrite control unit 312A sequentially receives the third and subsequent lines of the download file 23B (step ST49).

- the download file 23B includes the identification information 237 (in the case of “Yes” in step ST50)
- the rewrite control unit 312A obtains the identification information (identification ID) 237 from the received program data 231. Extracted and acquired (step ST51), and temporarily stored in an internal memory or register (step ST52).
- the identification information 237 of the download file 23B acquired and held here is identification information of the download file 23B treated as invalid for the first card reader 30A.
- step ST52 After the process of step ST52 or when the identification information 237 is not included in the download file 23B (“No” in step ST50), the rewrite control unit 312A does not execute the download command 234 for the received line. Then, a pseudo rewrite process is performed, and a normal response (pseudo response) that the download command 234 has been executed normally is returned to the download control unit 21 (step ST53).
- step S54 After the rewrite control unit 312A returns the normal response (pseudo response) that the download command 234 has been normally executed to the download control unit 21 by performing the pseudo rewrite process up to the last line of the download file 23B in step ST53.
- the invalid treated identification information 237 temporarily stored in step ST52 is stored (stored) in the identification information storage unit 32A (step S54).
- step ST47 when the program data stored in the host device 20 corresponds to a different type of card reader or the like (in the case of “No” in step ST47), the rewrite control unit 312A displays an error. A response is returned to the download control unit 21 (step ST55). The download control unit 21 that has received the abnormal response determines that the download of the program data 231 has failed and ends the download process.

If there is no transmission request from the higher-level device 20 in step ST58 (if “No” in step ST58), the processing of step ST59 is not executed and the next step from the higher-level device 20 is waited for.
- the same effect as that of the above-described embodiment can be obtained.
- the rewrite permission data 236 is included in the program data 231, even if the rewrite verification command 238 is not included in the download file 23 or the card reader 30 does not accept the rewrite verification command 238. It becomes possible to determine whether or not the download file 23 includes rewrite permission data.
- the same effect as that of the above-described embodiment can be obtained by performing the download process using the rewrite collation command and the identification information. That is, even if the host device is not replaced with a download file for new specifications, not only the pseudo-rewrite is performed on the sent download file but also a transmission request for identification information (identification ID) from the host device 20. Is received, the identification information (identification ID) of the invalid download file that has been pseudo-rewritten is returned, so that the subsequent download processing is not started and the processing can be shortened.
- the identification information (identification ID) of the downloaded file that has been pseudo-rewritten is returned even immediately after the download, so that a system stop can be avoided. Since an instruction to apply an inapplicable download file is excluded from the host device, its own operating environment is protected and it can be used continuously.

Abstract
Description
図1は、本発明の実施形態に係るファームウェアのダウンロードシステム10の概略構成を示すブロック図である。図2は、図1に示す上位装置20に記憶されるダウンロードファイルのデータ構造の一例を示す概念図である。図3は、図1に示す上位装置20に接続されるカードリーダ30と上位装置20に記憶されるダウンロードファイルとの組合せパターンを説明するための概念図である。
上位装置20は、ダウンロード制御部21、およびハードディスクドライブ等の外部記憶部22を含んで構成されている。ダウンロード制御部21は、上位装置20内の通信機能部や制御用プログラム等を含んで構成されている。ダウンロード制御部21は、カードリーダ30にプログラムデータ231(図2)をダウンロードするための制御を行う。
ここで、本実施形態に係るダウンロードファイル23の構造例について図2に関連付けて説明する。
カードリーダ30は、たとえば、カードを手動で移動させながらカードに記録された磁気データの読取り等を行う手動式のカードリーダ、あるいは、カードの搬送機構によってカードを搬送させながらカードに記録された磁気データの読取り等を行うカード搬送式のカードリーダにより構成される。
(1)ダウンロードの可能性がある、旧仕様用(旧型)のダウンロードファイルを受信した場合、正常にコマンドを受信したと上位装置20に疑似的にレスポンス(応答)を返すだけでなく、受信データの中から、その無効扱いの識別情報237を抽出(取得)し、周辺装置であるカードリーダ30内の不揮発性メモリ等の識別情報格納部32内に保持する。そして、識別情報格納部32に無効扱いの識別情報が記憶されているときには、要求に応じて識別情報として返す。
(2)新仕様用のダウンロードファイルを正常受信時は、まず、識別情報格納部32の無効扱いの識別情報の格納場所を消去する。すなわち、起動時に無効扱いの識別情報の格納場所が消去されていれば、要求に応じて、通常の識別情報を返す。
(3)また、受信するダウンロードファイル23の所定位置に識別情報がない場合は、上述したように、上位装置20が認識可能なダウンロードファイル23の識別情報を、新送付コマンドを用いて周辺装置であるカードリーダ30に送付する。カードリーダ30は、たとえば新コマンドで受信した識別情報を不揮発性メモリ等の識別情報格納部32内に格納(記憶)し、保持する。
[本実施形態ではない通常処理の場合]
通常は、まず「イレース」コマンド受信でファームウェア格納部311のプログラムデータが格納されている書き換え領域(エリア)を消去し、「ダウンロード」コマンド受信で書き込みを行う。
本実施形態では、以下の(1)~(5)に示すような処理が行われる。
ところで、本実施形態においては、上述のように、上位装置20には、第1カードリーダ30Aと第2カードリーダ30Bとが接続可能となっている。また、外部記憶部22には、第1カードリーダ30Aに対応するプログラムデータ231を含むダウンロードファイル23A、または、第2カードリーダ30Bに対応するプログラムデータ231を含むダウンロードファイル23Bが記憶されている。そのため、上位装置20に接続されるカードリーダ30と上位装置20に記憶されるダウンロードファイル23との組合せとして、図3に示す4つのパターンが考えられる。
まず、上位装置20におけるダウンロード処理を図4に関連付けて説明する。
図4は、図1に示す上位装置20における、ファームウェアのダウンロード時の処理フローの一例を示すフローチャートである。
次に、本実施形態に係る周辺装置であるカードリーダ30におけるダウンロード処理を図5に関連付けて説明する。図5は、図1に示すカードリーダ30における、ファームウェアのダウンロード時の処理フローの一例を示すフローチャートである。
以上説明したように、本実施形態によれば、ダウンロードファイル23に書き換え許可データ236が含まれている場合には、カードリーダ30に記憶されているプログラムデータが上位装置20から送られてくるプログラムデータ231に書き換えられる。一方、ダウンロードファイル23に書き換え許可データ236が含まれていない場合には、カードリーダ30に記憶されているプログラムデータが上位装置20から送られてくるプログラムデータ231に書き換えられない。すなわち、本実施形態によれば、基本的に、第1カードリーダ30Aに対応するプログラムデータ231が上位装置20に記憶されている場合には、第1カードリーダ30Aに記憶されているプログラムデータが上位装置20から送られてくるプログラムデータ231に書き換えられる。一方、第2カードリーダ30Bに対応するプログラムデータ231が上位装置20に記憶されている場合には、第1カードリーダ30Aに記憶されているプログラムデータが上位装置20から送られてくるプログラムデータ231に書き換えられない。そのため、本実施形態によれば、旧型の第2カードリーダ30Bに対応するプログラムデータ231が上位装置20から新型の第1カードリーダ30Aにダウンロードされることを防止することができる。したがって、本実施形態によれば、旧型の第2カードリーダ30Bに対応するプログラムデータ231が第1カードリーダ30Aにダウンロードされて、第1カードリーダ30Aが正常に動作しなくなるといった不具合を回避することが可能になる。
次に、他の実施形態として、ダウンロードファイルおよびダウンロード方法の変形例について説明する。図6は、本発明の他の実施形態に係るダウンロードファイル23のデータ構造の一例を示す概念図である。
[他の実施形態ではない通常処理の場合]
通常は、まず「照合」コマンドで書き換え(書き込み)照合を行い、照合がとれれば「イレース」コマンド受信でファームウェア格納部311のプログラムデータが格納されている書き換え領域(エリア)を消去し、「ダウンロード」コマンド受信で書き込みを行う。
本実施形態では、以下の(1)~(6)に示すような処理が行われる。
次に、本他の実施形態に係る周辺装置であるカードリーダ30におけるダウンロード処理を図7に関連付けて説明する。図7は、本発明の他の実施形態に係るカードリーダ30における、ファームウェアのダウンロード時の処理フローの一例を示すフローチャートである。
上述した実施形態および変形例は、本発明の好適な実施形態の一例ではあるが、これに限定されるものではなく本発明の要旨を変更しない範囲において種々変形実施が可能である。
