For example, control is performed so that a copy function, a printer function, a scan function, a facsimile function, and the like can be executed, and a process of setting a set value of an operation condition of a designated job by receiving an operation input of the operation panel 135 by a user is performed. Further, in this embodiment, when the application is installed, or when the application including the library is installed or after the installation, the library included in the application is extracted, and the same name and the same version as the extracted library are used. Is determined to be stored in the storage device 110, and if a library having the same name and the same version as the extracted library is stored, the library is compared with the extracted library by a difference. A process such as determining whether the contents (contents) are the same is performed, but details will be described later.

  The authentication unit 180 obtains authentication information of a user who logs in, and performs authentication by comparing and comparing the authentication information with verification information stored in advance in the fixed storage device 110 or the like. The comparison between the user authentication information and the verification information may be performed by an external authentication server, and the authentication may be performed by the authentication unit 180 receiving the authentication result from the authentication server.

  Next, the operation of the MFP 1 shown in FIG. 1 will be described.

  As shown in FIG. 2A, a storage device 110 which is a storage area (storage means) of the MFP 1 stores a library A (corresponding to a first library) which is a program used by one or a plurality of applications. It is assumed that 200 is stored.

  Next, in a state where the library A200 is stored, as shown in the figure, a new application B300 including the library A'210 (corresponding to the second library) having the same name and version as the library A200 is created. It is assumed that the MFP 1 is installed in the MFP 1.

  When the MFP 1 starts installation of the application B300 from the user's terminal device 2 or server (circled numeral 1), the application B300 is expanded on the S-RAM 103 and included in the library A ′ (hereinafter, also referred to as an included library). ) 210 is extracted, and the contents (contents) of the included library 210 and the library A 200 already stored in the storage device 110 are compared with each other on the RAM 103 to determine whether or not the contents are the same (circled numeral 2).

  The method for comparing the difference between the contents of the included library 210 and the library A200 is not limited. An example is a size comparison method for comparing the file sizes of both libraries. If the file sizes of both libraries are the same, it is determined that the contents are the same.

  Another example of the difference comparison method is a binary comparison method in which the binary data files of both libraries are compared. If the binary data files of both libraries are the same, it is determined that the contents are the same.

  Still another example of the difference comparison method is a checksum comparison method in which the checksums of both libraries are calculated and compared. If the checksums of both libraries are the same, the contents are determined to be the same.

  Another example of the difference comparison method is a source code comparison method in which the source code is compared when both libraries include the source code. Judge the same.

  By using such a difference comparison method, it is possible to accurately check whether there is a difference between the contents of the included library 210 and the library A 200 already stored in the storage device 110.

  If it is determined that there is a difference (not identical) between the contents of the included library 210 and the library A200 already stored in the storage device 110, the included library 210 may be a library customized from the library A200. The application B300 is installed while retaining 210 without deleting it from the application B300 (circled numeral 3).

  Therefore, as shown in FIG. 2B, the application B300 holding the included library 210 is stored in the storage device 110 of the MFP 1 in which the library A200 is already stored.

  After the application B300 is installed, when using the application B300, the CPU 101 of the MFP 1 preferentially uses the included application 210 of the application B300. That is, since the application B300 uses its own included application 210, it operates normally.

  In this manner, in this embodiment, when the application B300 including the library 210 is installed, the library 210 included in the application B300 is extracted, and the extracted included library 210 and the storage device 110 are already stored. It is determined whether the contents of the library A 200 are the same by comparing the differences. If there is a difference between the extracted included library 210 and the library A200 stored in the storage device 110, the application B300 is installed while the included library 210 is retained without being deleted. Further, since the application B 300 uses the inclusion library 210, the application B 300 operates properly according to the inclusion library 210.

  In the above embodiment, the inclusion library 210 is extracted when the application B 300 is installed, and the difference between the inclusion library 210 and the library A 200 already stored in the storage device 110 is compared. However, after the application B300 is installed, in other words, after the application B300 and the inclusion library 210 are stored in the storage device 110, the inclusion library 210 is extracted, and the inclusion library 210 and the library already stored in the storage device 110 are extracted. The difference of A200 may be compared.

  If there is no difference between the included library 210 and the library A200 already stored in the storage device 110, the included library may be deleted in order to effectively use the resources of the MFP 1.

  Next, another embodiment of the present invention will be described. In the above embodiment, even if the included library 210 included in the application 300 has the same name and version as the library A 200 stored in the storage device 110, if there is a difference in the contents, the included library 210 is left as it is. It was assumed to be retained.

  However, in this embodiment, if the included library 210 is a library relating to the unique function of the MFP 1, even if there is a difference in the contents, the application 300 is stored in the storage device 110 instead of the included library 210. The library A 200 is used preferentially.

  Libraries relating to functions unique to the MFP 1 are preset, and examples thereof include libraries relating to a printing operation and libraries relating to a scanning function of reading an original by the image reading apparatus 120 and converting the original into image data.

  As shown in FIG. 3, the storage device 110 of the MFP 1 has already stored libraries A200 to E204. In this example, the library A200 and the library B201 are customization libraries for printing, the library C202 is a security library, the library D203 is a communication library, and the library E204 is a scanning customization library. Libraries relating to functions unique to the MFP 1 are a library A200, a library B201, and a library E204.

  Next, when the library A200 is stored and a new application N300 including the library A'210 having the same name and version as the library A200 is installed in the MFP 1, as shown in FIG. think of.

  When the MFP 1 starts installing the application N300 from the user's terminal device 2 or server (circled number 1), the MFP 1 expands the application N300 on the S-RAM 103 and extracts the inclusion library 210. Then, after detecting the library A200 having the same name and version as the included library 210 from among the libraries, the contents (contents) of the included library 210 and the library A200 are compared with each other on the RAM 103 to determine whether or not they are the same ( Circle number 2).

  Here, even if it is determined that there is a difference (not the same) in the contents of the included library 210 and the library A200, the included library 210 is deleted because the library A200 is a print customization library that is a function unique to the MFP 1 ( Circle number 3). Thus, as shown in FIG. 4B, the library A 200 is used when the application N installed in the MFP 1 and stored in the storage device 110 operates. In FIG. 4B, other libraries B201 to E204 are omitted.

  In addition, instead of deleting the included library 210, the application N keeps the same as it is. However, when the application N operates, control may be performed such that use of the included library 210 is prohibited and the library A200 is used.

  As described above, by using the library A 200 preferentially during the operation of the application N due to the use prohibition including the deletion of the included library 210, it is possible to minimize the possibility of affecting the print operation which is a unique function of the MFP 1. Can be.

  The same applies to the case where the included library 210 has the same name and version as the library E204 which is a scan customization library.

  FIG. 5 is a flowchart illustrating an operation of MFP 1 when application 300 including library 210 is installed. The operation shown in this flowchart is executed when CPU 101 of MFP 1 operates according to an operation program stored in a recording medium such as ROM 102.

  In step S01, the installation of the application 300 is started. In step S02, it is checked whether or not the library holding state in the application 300, in other words, the included library 210 exists.

  Next, in step S03, the presence or absence of the inclusion library 210 is determined. If the included library 210 does not exist (NO in step S03), the installation of the application 300 is continued and completed in step S10. If the inclusive library 210 exists (YES in step S03), the inclusive library 210 is extracted in step S04, and in step S05, the library having the same name and the same version as the extracted inclusive library 210 is stored in the storage device 110 of the MFP 1 in step S05. It is determined whether A200 exists.

  If there is no library A200 having the same name and the same version as the extracted included library 210 (NO in step S05), the process proceeds to step S10, where the installation of the application 300 is continued and completed. If there is a library A200 having the same name and the same version as the included library 210 (YES in step S05), in step S06, after comparing the corresponding library A200 in the storage device 110 with the extracted included library 210, the difference is compared. In S07, it is determined whether there is a difference.

  If there is no difference (NO in step S07), the contents of the two libraries are the same. Therefore, after deleting the included library 210 in step S09, only the application 300 is installed in step S10.

  If there is a difference in step S07 (YES in step S07), in step S08, library A200 determines whether or not the library is a library related to a function unique to MFP1. If the library is not a library related to the unique function of the MFP 1 (NO in step S08), the application 300 holding the included application 210 is installed in step S10. If it is a library related to the unique function of the MFP 1 (YES in step S08), after deleting the included library 210 in step S9, only the application 300 is installed in step S10.
