  Next, the operation of the MFP 20 will be described.

  A user of the MFP 20, such as a service person, transmits an installation package file from the computer 40 to the MFP 20 by using a tool (not shown) of the computer 40, and the Java application based on the installation package file transmitted from the computer 40 to the MFP 20. It is possible to instruct the MFP 20 to install the execution file.

  FIG. 8 is a flowchart of the operation of the MFP 20 when installing an execution file of a Java application.

  As shown in FIG. 8, the installation unit 28c decompresses the compressed application file included in the installation package file (S101). Therefore, in the case of the installation package file 50, the application file 53 is generated. In the case of the installation package file 60, an application file 63, version correspondence information 64, and a compressed new version application file 65 are generated.

  After the process of S101, the installation unit 28c installs the execution file in the application file generated by the process of S101 as the execution file 27b in the MFP 20 itself (S102), and ends the operation shown in FIG.

  In the above, installation of the execution file of the Java application by the installation package file transmitted from the computer 40 to the MFP 20 has been described. However, the MFP 20 operates in the same manner when the user of the MFP 20 instructs the MFP 20 via the operation unit 21 of the MFP 20 to install the execution file of the Java application using the installation package file stored in the storage medium 70.

  Next, the operation of the MFP 30 will be described.

  A user of the MFP 30, such as a service person, transmits an installation package file from the computer 40 to the MFP 30 by using a tool (not shown) of the computer 40, and the Java application based on the installation package file transmitted from the computer 40 to the MFP 30. It is possible to instruct the MFP 30 to install the execution file.

  FIG. 9 is a flowchart of the operation of the MFP 30 when installing an execution file of a Java application.

  As shown in FIG. 9, the installation unit 38d decompresses the compressed application file included in the installation package file (S131). Therefore, in the case of the installation package file 50, the application file 53 is generated. In the case of the installation package file 60, an application file 63, version correspondence information 64, and a compressed new version application file 65 are generated.

  The optimum version determination unit 38c determines whether version correspondence information has been generated by the process of S131 after the process of S131 (S132).

  If it is determined in S132 that the version correspondence information has not been generated, the installation unit 38d installs the execution file in the application file generated by the processing of S131 as the execution file 37b in the MFP 30 itself (S133), and FIG. End the indicated operation.

  When it is determined in S132 that the version correspondence information has been generated, the optimal version determination unit 38c determines whether or not the optimal compressed new version application file for the MFP 30 exists in the compressed new version application file generated by the process in S131. The determination is made based on the version correspondence information generated by the process of S131 (S134).

  If it is determined in S134 that the optimum compressed new version application file exists, the installation unit 38d deletes data other than the optimum compressed new version application file from the data generated by the process of S131 (S135). That is, the installation unit 38d deletes the application file and version correspondence information generated by the process of S131, and among the compressed new version application files generated by the process of S131, the compressed new version other than the optimal compressed new version application file Delete app files.

  After the process of S135, the installation unit 38d decompresses the remaining compressed new version application file (S136). Therefore, when the installation package file 60 is used, the application file 66 included in the optimum compressed new version application file is generated.

  After the process of S136, the installation unit 38d installs the execution file in the application file generated by the process of S136 as the execution file 37b in the MFP 30 itself (S137), and ends the operation shown in FIG.

  If it is determined in S134 that the optimum compressed new version application file does not exist, the installing unit 38d compresses the new version application file (hereinafter referred to as "latest compressed file") of the latest version of the Java application among the data generated by the process of S131. Data other than “new version application file” is deleted (S138). That is, the installation unit 38d deletes the application file and the version correspondence information generated by the process of S131, and among the compressed new version application files generated by the process of S131, the compressed new version other than the latest compressed new version application file Delete app files.

  After the process of S138, the installation unit 38d decompresses the remaining compressed new version application file (S139). Therefore, when the installation package file 60 is used, the application file 66 included in the latest compressed new version application file is generated.

  After the process of S139, the installation unit 38d installs the execution file in the application file generated by the process of S139 as the execution file 37b in the MFP 30 itself (S140), and ends the operation illustrated in FIG.

  In the above, installation of the execution file of the Java application by the installation package file transmitted from the computer 40 to the MFP 30 has been described. However, the MFP 30 operates in the same manner when the user of the MFP 30 instructs the MFP 30 via the operation unit 31 of the MFP 30 to install the execution file of the Java application using the installation package file stored in the storage medium 70.

  As described above, the installation package file 60 includes the optimum compressed new version application file for the MFP when the MFP has the optimum version determination function (YES in S134). Is extracted (S136), and the acquired Java application executable file 66a is installed in the MFP itself (S137). In addition, when the MFP does not have the optimum version determination function, the Java application included in the application file 63 is included. Since the MFP installs the execution file 63a in the MFP itself (S102), the MFP can install the execution file of the Java application in the MFP itself even if the MFP does not have the optimum version determination function. Therefore, the installation package file 60 can increase the number of MFPs that can install the execution file of the Java application.

  Further, when the MFP has an optimum version determination function, the installation package file 60 does not include the optimum compressed new version application file for the MFP (NO in S134), and the compressed new version application file included in the installation package file 60 65, the latest compressed new version application file is decompressed by the MFP (S139), and the acquired Java application execution file 66a is installed in the MFP itself (S140), so even if the optimum compressed new version application file for the MFP is not included. The MFP can install the execution file of the Java application in the MFP itself. Therefore, the installation package file 60 can increase the number of MFPs that can install the execution file of the Java application.

  Note that when a Java application is optimally created for a certain version of JavaVM, it may not operate properly on a version of JavaVM prior to that version. Therefore, when an installation package file such as the installation package file 50 is created for each version of the Java application, the user who installs the execution file of the Java application in the MFP using the installation package file can install the Java VM version of the MFP, The installation package file to be used must be selected based on the Java application version of the package file. However, since the installation package file 60 does not allow the user to select an appropriate version, it is possible to suppress the occurrence of a mistake in the version of the executable file of the Java application to be installed and to reduce the burden on the user. it can.

  The application of the present invention is a Java application in the present embodiment, but may be an application other than the Java application.

  The electronic apparatus according to the present invention is an MFP in the present embodiment, but may be an image forming apparatus other than the MFP, such as a printer dedicated machine or a copy dedicated machine, or an electronic apparatus other than the image forming apparatus such as a PC.
