The PC 10 can download the package 120 and the single installer corresponding to the model of the target device from the server 200.

  FIG. 2 is a schematic diagram showing an example of an overall user interface (hereinafter referred to as “overall UI”) 50 displayed on the LCD 18 by the user interface function of the main body program 122. More specifically, FIG. 2A shows a state in which only the initial installation is performed, that is, a state in which the basic function execution unit 123 is installed but a single function execution unit 141 is not installed at all. An overall UI 50 is shown. On the other hand, FIG. 2B shows the entire UI 50 when the function button 51b is operated from the state shown in FIG.

  The overall UI 50 displays various function buttons for inputting each function and an execution instruction for the function realized by the information processing apparatus using each function for each function realized by the device. Specifically, in the present embodiment, the MFP 30 is configured to be able to implement a scan function, a print function, a copy function, and a facsimile function, so that function buttons are respectively displayed in areas 51 to 54 corresponding to these functions. 51a to 51d, function buttons 52a and 52b, function button 53a, and function buttons 54a and 54b are displayed.

  A state in which a cursor (not shown) is positioned on any one of the function buttons 51a to 51d, 52a, 52b, 53a, 54a, and 54b based on the first operation on the input device 17 Thus, by performing the second operation on the input device 17, an execution instruction for the function corresponding to the function button indicated by the cursor is input. When the input device 17 is a mouse, for example, the first operation is, for example, an operation of moving the mouse, and the second operation is, for example, a left click operation.

  According to the device usage application 100 of the present embodiment, only the function buttons corresponding to the installed basic function execution unit 123 or the single function execution unit 141 are displayed in the original color of the button, and other function buttons, that is, Function buttons corresponding to single functions that are not installed are displayed in gray out. In the example shown in FIGS. 2A and 2B, the gray-out display is represented by hatched hatching.

  Therefore, at the stage where the initial installation is performed, only the function buttons 51a, 52a, and 52b corresponding to the basic functions realized by the basic function execution unit 123 already installed at this stage are displayed in the original color of the buttons. The other function buttons, that is, the function buttons 51c, 51d, 53a, 54a, and 54b corresponding to the single functions that have not been installed are displayed in gray out. In the present embodiment, it is possible to input an execution instruction to the function button regardless of whether the function button is displayed in the original color of the button or in a grayout display.

  As described above, when an instruction to execute a single function that has not been installed by the corresponding single function execution unit 141 is input, the corresponding single function execution unit 141 is installed in the information processing apparatus. Therefore, for example, when an execution instruction is input to the function button 51b grayed out in the overall UI 50 shown in FIG. 2A, the single function execution unit 141 corresponding to the function button 51b is described in more detail. The text conversion program 141a is installed in the information processing apparatus. As the text conversion program 141a is installed, the function button 51b that is the target of the execution instruction changes from grayout display to display in the original color of the button. As described above, whether or not the basic function execution unit 123 or the single function execution unit 141 is installed can be distinguished by the display color of the function button in the entire UI 50, so that the user can determine the function execution unit from the display color of the function button. 123 and 141 can be grasped.

  The entire UI 50 is provided with a pull-down button 55. Based on the first operation on the input device 17, a model list display instruction can be input by performing a predetermined operation on the input device 17 with the cursor positioned on the pull-down button 55. . When a model list display instruction is input, the model list is displayed as a pull-down list. The model list is a list of models that can correspond to the device utilization application 100, that is, the main body program 122. The model list is included in the main body installer 121 as one of various setting information necessary for device control, and a specific location in the HDD 14 that is managed by the OS via the entire UI 50 when the main body program 122 is installed. (For example, a system folder).

  With reference to FIG. 3 and FIG. 4, each process executed by the CPU 11 according to the main body installer 121 or the main body program 122 installed in the PC 10 that is the information processing apparatus will be described. FIG. 3A is a flowchart showing the initial installation process executed by the CPU 11 in accordance with the main body installer 121. This process is started when the main body installer 121 included in the initial installation package 120 downloaded by the PC 10 from the server 200 is started. The package 120 downloaded from the server 200 is a package corresponding to the model of the target device (MFP 30 in this embodiment).

  The CPU 11 installs the main body program 122 included in the package 120 (S301). As the main body program 122 is installed, a user interface function and an information acquisition function included in the main body program 122 can be used. Next, the CPU 11 installs the basic function execution unit 123 included in the package 120 (S302). In the present embodiment, the CPU 11 installs a scanner driver 123a and a printer driver 123b. Since the package 120 downloaded from the server 200 corresponds to the model of the target device (hereinafter referred to as “target model”), the basic function execution unit 123 installed in the PC 10 by the process of S302 is performed. The basic function execution unit 123 corresponding to the target model.

  The CPU 11 creates an installation status list in the storage area of the HDD 14 associated with the main body program 122 (S303), and ends this process. The installation status list is a list of models in which the basic function execution unit 123 or the single function execution unit is installed among devices that can support the device utilization application 100. Therefore, in S303, the CPU 11 creates an installation status list in which the current target model is listed as a model in which the basic function execution unit 123 has been installed. In the installation status list, the last use date of the device is stored in association with each model in which the basic function execution unit 123 or the single function execution unit 141 is installed.

  FIG. 3B is a flowchart showing a single installation thread executed by the CPU 11 in accordance with the main body program 122 installed in the PC 10. In this thread, among the function buttons 51a to 51d, 52a, 52b, 53a, 54a, 54b, the CPU 11 inputs an execution instruction for a function button of a single function in which the corresponding single function execution unit 141 is not installed. It is created when accepted (see S410 in FIG. 4).

  Based on the performance information acquired from the target device, the CPU 11 downloads a single function single installer corresponding to the function button to be executed from the server 200 (S321). That is, for example, when the function button that is the target of the execution instruction is the function button 53a corresponding to the copy function, and the performance information indicates that the target device is not a color-compatible model, the CPU 11 The download instruction of the copy processing program 141d configured only by the server is transmitted to the server 200, and the single installer corresponding to the copy processing program 141d configured by only the monochrome copy processing program is downloaded from the server 200.

  Next, the CPU 11 activates the downloaded standalone installer, installs the standalone function execution unit 141 included in the standalone installer (S322), and ends this process. As described above, when an execution instruction for a single function depending on the performance of the device is input, a single installer corresponding to the performance of the device is downloaded, so that the single function execution unit 141 not suitable for the performance of the device It can be prevented from being installed. Further, for example, when the target device is not a color compatible model, a single function execution unit 141 that does not include a color compatible program such as a copy processing program 141d configured only by a monochrome copy processing program is installed, which is unnecessary. The program can be prevented from being installed.

  FIG. 3C is a flowchart showing model switching processing (S419, S421) executed by the CPU 11 in accordance with the main body program 122 installed in the PC 10. This process is a process executed in a process described later with reference to FIG. 4 and is a process for switching from the current target device to a device of another model.

  First, the CPU 11 displays a model list, which is a pull-down list, on the entire UI 50 (S341). The CPU 11 waits for one model to be selected from the displayed model list in accordance with a predetermined operation on the input device 17 (S342: No). When one model is selected (S342: Yes), the CPU 11 refers to the installation status list and determines whether the basic function execution unit 123 of the selected model has been installed (S344).

  When the CPU 11 determines that the basic function execution unit 123 of the selected model has not been installed (S344: No), the CPU 11 executes the installation of the basic function execution unit 123 of the selected model (S345). Specifically, the CPU 11 transmits a download instruction of the basic function execution unit 123 of the selected model to the server 200, and installs the corresponding basic function execution unit 123 and the basic function execution unit 123 from the server 200. Download the installer including the installation program. Then, the downloaded installer is activated, and the basic function execution unit 123 included in the installer is installed.

  The CPU 11 updates the installation status list by adding the model selected from the model list as a model already installed by the basic function execution unit 123 (S346). The CPU 11 switches the target device to the selected model (S347) and ends this process. On the other hand, when the CPU 11 determines in S344 that the basic function execution unit 123 of the selected model has been installed (S344: Yes), the CPU 11 skips the processes of S345 and S346 and executes the process of S347. To do.

  FIG. 4 is a flowchart showing main body program processing executed by the CPU 11 in accordance with the main body program 122 installed in the PC 10. This process is started when the main body program 10 installed in the PC 10 is activated. The CPU 11 refers to the installation status list, and creates a list of models that have passed a predetermined period or more from the last use date, in this embodiment, one month or more (S401). If the created list is not empty (S402: No), the CPU 11 uninstalls the single function execution unit 141 of a model in the list, that is, a model that has passed one month or more from the last use date (S403).

  Therefore, since a model that is not used for a certain period of time is less likely to be used in the future, it is possible to effectively use the storage capacity of the HDD 14 by uninstalling the single function execution unit 141 from the device of the model. On the other hand, the basic function execution unit 123 is left installed. Even if the model is not used for a certain period of time, the basic function is relatively likely to be used. Therefore, by not uninstalling the basic function execution unit 123, it is immediately possible to use the basic function in the model. Available. In S403, not only the single function execution unit 141 but also the basic function execution unit 123 may be uninstalled. In such a case, the storage capacity of the HDD 14 can be used more effectively as much as the basic function execution unit 123 is uninstalled.

  In the present embodiment, the CPU 11 uninstalls the single function execution unit 141 in S403, but the single installer corresponding to the single function execution unit 141 to be uninstalled is not deleted from the HDD 14 and remains stored in the HDD 14. . By leaving the stand-alone installer, when reinstalling the uninstalled stand-alone function execution unit 141, it is not necessary to install the stand-alone installer again, so that the reinstallation can be easily performed and the time required for the reinstallation can be reduced. Can be shortened. Note that the corresponding single installer may be deleted from the HDD 14 when the single function execution unit 141 is uninstalled. In such a case, the storage capacity of the HDD 14 can be effectively used as much as the single installer is deleted.

  Next, the CPU 11 updates the installation status list by deleting the information related to the uninstalled single function execution unit 141 (S404), and the process proceeds to S405. On the other hand, when the list created in S401 is empty (S402: Yes), the CPU 11 skips the processes of S403 and S404, and moves the process to S405.

  In S405, the CPU 11 refers to the installation status list and selects one model from the models in which the basic function execution unit 123 or the single function execution unit 141 has been installed (S405). In the present embodiment, the CPU 11 selects the model used last time in S405. Alternatively, it may be configured to select a model specified when the main body program 122 is started or a model specified as a default.

  The CPU 11 displays the entire UI 50 on the LCD 18 (S406). The CPU 11 waits for an execution instruction for a function button, a model list display instruction, or an end instruction to be input (S407: No, S419: No, S422: No).

  When the CPU 11 accepts an execution instruction input to the function button (S407: Yes), the CPU 11 has installed the function execution unit of the function that is the target of the execution instruction, that is, the basic function execution unit 122 or the single function execution unit 141. Is determined from the installation status list (S408). When the CPU 11 determines that the function execution unit of the function that is the target of the execution instruction is not installed (S408: No), the CPU 11 acquires performance information from the target device using the information acquisition function (S409). The CPU 11 creates a single installation thread (S410). As a result of the processing of S410, the CPU 11 executes the above-described single installation thread (FIG. 3B) in parallel with this processing.

  After the processing of S410, the CPU 11 displays a function setting user interface (not shown) (hereinafter referred to as “function setting UI”) on the LCD 18 (S411). The function setting UI is a user interface for setting a setting value for a function that is an execution instruction target. For example, when the function that is the target of the execution instruction is a function that uses the scan function of the device, setting values such as resolution and document size can be set to appropriate values in the function setting UI. In the present embodiment, when the function that is the target of the execution instruction uses the copy function or facsimile transmission function of the device, or when the target device is a color-compatible model, the function corresponding to color processing is performed in the function setting UI. Or monochrome processing is selectable via the function setting UI. When the CPU 11 determines that the function execution unit of the function that is the target of the execution instruction is installed (S408: Yes), the CPU 11 skips the processes of S409 and S410 and executes the process of S411.

  After displaying the function setting UI, the CPU 11 waits for the setting by the function setting UI to end (S412: No). When the setting by the function setting UI is finished (S412: Yes), when the created single installation thread is finished (S413: Yes, S414: Yes), the CPU 11 is currently installed on the target device. The installation status list is updated by adding the single function execution unit 141 as already installed (S415). After the process of S415, the CPU 11 executes the process of the function that is the target of the execution instruction (S416).

  On the other hand, if the created single installation thread has not ended, the CPU 11 waits for processing until the single installation thread ends (S414: No). If a single installation thread has not been created (S413: No), the CPU 11 moves the process to S416 and executes the process of the function that is the target of the execution instruction.

  The CPU 11 determines whether or not the process executed in S416 is successful (S417). Specifically, when the CPU 11 detects a signal indicating the completion of the process from the device within a predetermined time from the start of the process, the CPU 11 determines that the process is successful. On the other hand, when the CPU 11 cannot detect a signal indicating the completion of processing from the device within a predetermined time from the start of the processing, or when the CPU 11 detects an error signal input from the device, The CPU 11 determines that the process has not been successful.

  When the CPU 11 determines that the process executed in S416 is successful (S417: Yes), the CPU 11 currently counts the last use date corresponding to the model indicating the target device in the installation status list by an RTC (not shown). The date is updated (S418), and the process proceeds to S407. On the other hand, if the CPU 11 determines that the process executed in S416 has not been successful (S417: No), the above-described model switching process in FIG. 3C is executed (S419), and the process proceeds to S408. If it is determined No in S417, the model list is automatically displayed in S341 of the model switching process regardless of the operation on the pull-down button 55. Therefore, when the function that is the target of the execution instruction is unsuccessful in the selected device, the function can be realized by using another model device.

  When the CPU 11 receives an input of a model list display instruction, that is, an operation on the pull-down button 55 (S407: No, S420: Yes), the CPU 11 executes the above-described model switching process of FIG. S421), the process proceeds to S416. In addition, when the CPU 11 receives an input of an end instruction, for example, an operation for an end button provided on the entire UI 50 (S420: No, S422: Yes), the CPU 11 ends the present process.

  According to the first embodiment, at the time of initial installation, only the main body program 122 and the basic function execution unit 123 included in the package 120 are installed in the PC 10. Therefore, since the single function execution unit 141 is not downloaded and installed during the initial installation, the time required for the initial installation can be shortened accordingly. On the other hand, since the basic function execution unit 123 is installed at the time of initial installation, the basic function can be used immediately after the initial installation.

  Moreover, since the function setting UI is displayed while the single function execution unit 141 can be installed in the PC 10 using the execution instruction input to the function button as a trigger, the single function execution unit to be installed is displayed via the function setting UI. The set value can be set to an appropriate value for the single function corresponding to 141. Therefore, immediately after the single function execution unit 141 is installed, the function corresponding to the installed single function execution unit 141 can be used with a suitable setting value. In particular, since the installation of the single function execution unit 141 is executed in parallel with the display of the function setting UI, the single function execution unit 141 can be efficiently installed using the input period of the set value.

  In addition, if the setting by the function setting UI is completed before the installation of the single installer is completed, the completion of the installation is waited, and the single function that is the target of execution is executed on the condition that the installation is completed. Therefore, it is possible to minimize the period from when the execution instruction for the single function is given until the single function is executed with a suitable set value.

  Further, even if the model is different from the model corresponding to the package 120 used at the time of initial installation, if the device is compatible with the device use application 100, the main program 122 installed at the time of initial installation is used. Since the basic function execution unit 123 can be installed on the PC 10, it is not necessary to separately download an installer corresponding to the basic function execution unit 123 corresponding to another model, and the basic function execution unit 123 corresponding to another model can be easily installed. it can.

  Next, a second embodiment of the present invention will be described with reference to FIG. In the first embodiment described above, the single installer is downloaded from the server 200, but in the second embodiment, the single installer can be downloaded from the device. In the second embodiment, the device acquires a single installer including a single function execution unit 141 corresponding to a single function of the device from the server 200 and stores the acquired single installer in a flash memory or the like. It is a premise. In the second embodiment, the same parts as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted. Hereinafter, the configuration unique to the second embodiment will be mainly described.

  FIG. 5 is a flowchart showing the main body program processing of the second embodiment. This process is a process executed by the CPU 11 in accordance with the main body program 122 of the second embodiment. This process is started when the main body program 122 of the second embodiment installed in the PC 10 is started.

  In S408, when the CPU 11 determines that the function execution unit of the function that is the target of the execution instruction is not installed (S408: No), the CPU 11 acquires performance information from the target device (S409), and the target device is The version of the single installer of the single function corresponding to the function button that is the target of the execution instruction is acquired (S501). Next, the CPU 11 acquires the version of the single installer of the single function corresponding to the function button that is the target of the execution instruction and is disclosed on the server 200 (S502).

  The CPU 11 determines which version of the single installer is newer in the target device and the server 200 (S503). When the CPU 11 determines that the device is newer (S503: device), the CPU 11 selects a single installer for the single function corresponding to the function button that is the target of the execution instruction based on the performance information acquired in S409. (S506).

  On the other hand, when the CPU 11 determines that the server 200 is newer (S503: server), the CPU 11 installs a single installer for the single function corresponding to the function button that is the target of the execution instruction based on the performance information acquired in S409. Download from the server 200 (S504). After the processing of S504 or S506, the CPU 11 activates the downloaded single installer, executes the installation of the single function execution unit 141 included in the single installer (S505), and shifts the processing to S415.

  According to the second embodiment, since the single installer can be downloaded from the device, the time required for acquiring the single installer can be shortened as compared with the case where the single installer is acquired from the server 200 on the Internet 500. Also, if the version of the single installer published on the server 200 is newer than that held in the device, the new single installer is downloaded from the server 200, so the old version single function execution unit 141 is downloaded. Can be prevented from being installed.

  Next, a third embodiment of the present invention will be described with reference to FIGS. In the above-described first embodiment, when an execution instruction is input to a function button, the non-installed single function execution unit 141 corresponding to the function button is installed. In the embodiment, all the single function execution units 141 are configured to be installed in a batch regardless of the input of the execution instruction to the function buttons as necessary. In the third embodiment, the same portions as those in the first embodiment and the second embodiment are denoted by the same reference numerals, and the description thereof is omitted. Hereinafter, the processing unique to the third embodiment will be mainly described. Hereinafter, the configuration unique to the third embodiment will be mainly described.

  FIG. 6A is a flowchart showing the initial installation process of the third embodiment. This process is a process executed by the CPU 11 according to the main body installer 121 of the third embodiment. This process is started when the main body installer 121 of the third embodiment included in the initial installation package 120 is started.

After installing the main body program and the basic function execution unit 123 (S301, S302), the CPU 11 causes the LCD 18 to display an installation method selection screen of the single function execution unit 141 (S601). The selection screen installs the target device, that is, the single function execution unit 141 that can be used by the device corresponding to the main body installer 121 that executes this process, one by one with an input of an execution instruction for the function button as a trigger, This is a screen for selecting whether to install all at once regardless of the execution instruction input to the function buttons. In the latter installation method, it is possible to select whether to install all the single function execution units 141 continuously or sequentially using the free time of the PC 10. The “free time of the PC 10” is a period in which a predetermined situation in which it is considered that the PC 10 cannot be controlled is high. In this embodiment, the PC 10 can realize a function using a device, that is, a basic function. This is a period in which neither a function nor a single function is being executed.

  On the selection screen, when it is selected that all the single function execution units 141 are to be installed collectively and they are selected to be installed sequentially using the free time of the PC 10 (S602: Yes, S603: Yes) The CPU 11 sequentially sets the installation flag to ON (S604), and the process proceeds to S303. The sequential installation flag is a flag indicating whether or not the sequential installation using the free time (hereinafter referred to as “sequential installation”) is being performed, and is provided in the storage area of the HDD 14 associated with the main body program 122. It is done. When the sequential installation flag is set to ON, it indicates that the sequential installation is being executed. The sequential installation flag is set to OFF with the start of this process.

  On the other hand, when it is selected that all the single function execution units 141 are installed in a batch, and all the single function execution units 141 are selected to be installed in a batch instead of using free time ( (S602: Yes, S603: No), the CPU 11 acquires performance information from the target device in the same manner as in S409 (S605). Based on the performance information acquired in S605, the CPU 11 downloads all the single installers corresponding to all the single functions available in the target device from the server 200 (S606). The CPU 11 installs all the single function execution units 141 using all the downloaded single installers (S607), and shifts the processing to S303.

  FIG. 6B is a flowchart showing a single installation thread executed by the CPU 11 in accordance with the main body program 122 of the third embodiment installed in the PC 10. This thread is created on the condition that it is an install flag sequentially when the main body program process of the third embodiment described later is started (see S702 in FIG. 7).

  For the target device, the CPU 11 creates a list of unit function execution units 141 that are not installed among the unit function execution units 141 that can use the device (S621). If the created list is not empty (S622: No), the CPU 11 acquires performance information from the target device in the same manner as in S409 (S623). The CPU 11 downloads a single installer corresponding to the single function execution unit 141 corresponding to the performance information acquired in S623 from the server 200, which is the single function execution unit 141 at the top of the list (S624).

  The CPU 11 activates the downloaded single installer, installs the single function execution unit 141 included in the single installer (S625), and updates the installation status list in the same manner as S415 (S626). The CPU 11 deletes the installed single function execution unit 141 from the list (S627), and the process proceeds to S622. If the list is empty (S622: Yes), the CPU 11 sequentially sets the installation flag to OFF (S628), and ends this process.

  FIG. 7 is a flowchart showing the main body program processing of the third embodiment. This process is a process executed by the CPU 11 according to the main body program 122 of the third embodiment. This process is started when the main body program 122 of the third embodiment installed in the PC 10 is started.

  After the entire UI 50 is displayed (S406), if the sequential installation flag is set to ON (S701: Yes), the CPU 11 sequentially creates installation threads (S702), and the process proceeds to S407. As a result of the processing in S702, the CPU 11 executes the above-described sequential installation thread (FIG. 6B) in parallel with this processing. On the other hand, when the install flag is not sequentially set to ON (S701: No), the CPU 11 skips the process of S702 and shifts the process to S407.

  When the CPU 11 accepts an execution instruction input to the function button (S407: Yes), if the sequential installation flag is set to ON (S703: Yes), the sequential installation thread being executed is temporarily suspended (S704). The process proceeds to S408. In step S704, the processing of the installation flag may be stopped in a state at the execution timing of the processing in step S704, or one unit of processing such as download or installation executed at that time may end. It is good also as a structure which waits and stops. Or it is good also as a structure which waits for completion | finish of a series of processes (S623-S627) for installing the single function execution part 141, and stops an installation thread | sled sequentially. On the other hand, if the install flag is not sequentially set to ON in S703 (S703: No), the CPU 11 skips the process of S704 and shifts the process to S408.

  After the process of S416, when the sequential installation flag is set to ON (S705: Yes), the CPU 11 resumes the execution of the sequential installation thread suspended in S704 (S706), and the process proceeds to S407. . On the other hand, if the install flag is not sequentially set to ON in S705 (S705: No), the CPU 11 skips the process of S706 and shifts the process to S407.

  According to the third embodiment, if necessary, all the single function execution units 141 can be installed together regardless of the execution instruction input to the function buttons, so that the single function execution unit 141 can be installed. You can install it according to your convenience. In particular, when all the unit function execution units 141 are installed at a time, it is possible to select whether to perform the installation continuously or sequentially using the free time of the PC 10. When the latter method is selected, the control load on the PC 10 is suppressed, so that delays in download time and installation time can be suppressed.

  Next, a fourth embodiment of the present invention will be described with reference to FIG. In the first embodiment described above, when the execution instruction is input to the function button, only the single function execution unit 141 corresponding to the function button is installed. However, in the fourth embodiment, other Is configured so that it can be installed if necessary. In the fourth embodiment, the same portions as those in the first to third embodiments are denoted by the same reference numerals, and the description thereof is omitted. Hereinafter, the processing unique to the fourth embodiment will be mainly described. Hereinafter, the configuration unique to the fourth embodiment will be mainly described.

  FIG. 8 is a flowchart showing the main body program processing of the fourth embodiment. This process is a process executed by the CPU 11 according to the main body program 122 of the fourth embodiment. This process is started when the main body program 122 of the fourth embodiment installed in the PC 10 is started.

  When the CPU 11 determines in S408 that the function execution unit of the function that is the target of the execution instruction has not been installed (S408: No), the CPU 11 executes the processing of S409 and S410, and then performs the function-specific installation status screen. Is displayed (S801). The function-specific installation status screen is a screen showing the installation status of the basic function and the single function of the target device. On the screen, a check box is displayed for each of the basic function and the single function of the target device. When the function-specific installation status screen is displayed in the process of S801, the CPU 11 refers to the installation status list and displays a check in a check box corresponding to the installed function. An empty check box displayed on the function-specific installation status screen can be checked as necessary based on a predetermined operation on the input device 17.

  If all the single installation threads have not ended after the processing of S801 (S802: No), the CPU 11 determines whether a check box for a single function that has not been installed is checked on the function-specific installation status screen. (S804). When the CPU 11 determines that the check box is not checked (S804: No), the CPU 1 shifts the process to S802. On the other hand, when the CPU 11 determines that the check is entered (S804: Yes), the CPU 11 creates a single installation thread corresponding to the single function that is checked (S805). As a result of the processing in S805, the above-described single installation thread (FIG. 3B) is executed in parallel with this processing, as in S410. However, in the single installation thread created in S805, in S321, the CPU 11 downloads a single installation thread corresponding to the checked single function based on the performance information acquired in S409.

  After the process of S805, the CPU 11 moves the process to S802. If all the single installation threads are completed (S802: Yes), the CPU 11 deletes the function-specific installation status screen (S803), and the process proceeds to S415.

  According to the fourth embodiment, when an execution instruction is input to a function button, not only the single function execution unit 141 that is the target of the execution instruction but also an installation target via the function-specific installation status screen. Since the selected single function execution unit 141 can be installed, the single function execution unit 141 can be installed as much as necessary at one time.

  Although the present invention has been described based on the embodiments, the present invention is not limited to the above-described embodiments, and various improvements and modifications can be easily made without departing from the spirit of the present invention. Can be inferred.

  For example, in the above-described embodiment, the MFP 30 that is a multi-function peripheral device is illustrated as a device corresponding to the device use application 100. However, an apparatus having only a single function such as a scanner or a printer may be employed. In the above-described embodiment, the PC 10 is exemplified as the information processing apparatus to which the device usage application 100 is applied. However, a mobile terminal such as a smartphone, a tablet terminal, or the like may be employed.

  In the above embodiment, the single installer is configured to be downloaded from the server 200 on the Internet 500 or a device on the LAN 40. However, it is acquired from another storage location, for example, a management server of a device installed on the LAN 40. It is good also as composition to do. In the above embodiment, the performance information is acquired from the device on the LAN 40. However, the performance information is acquired from another storage location, for example, the management server of the device installed on the LAN 40 or the Internet 500. Also good. A management server that stores a program such as a standalone installer is a type of storage medium that can be read by a computer.

  In the above embodiment, the initial installation package 120 includes the basic function execution unit 123 corresponding to one model. However, the basic execution unit 123 corresponding to all models compatible with the device use application 100 is used. In the first installation, the basic function execution unit 123 corresponding to the specified one model may be installed. However, it is preferable that the initial installation package 120 includes only the basic function execution unit 123 corresponding to one model because the time required for downloading the package 120 is shortened as in the above embodiment.

  According to the main body program processing (FIG. 4) of the first embodiment, the unit function execution unit 141 corresponding to the model that has passed one month or more from the last use date is uninstalled. A basic function or a single function that has not been used for a period of time may be uninstalled. In this modified example, the last use date is managed for each function in the installation status list, and in S401, in the model in which one month or more has passed since the last use date, the CPU 11 has passed one month or more from the last use date. A configuration that creates a list of functions may be used. Also in the case of such a modification, the storage capacity of the HDD 14 can be effectively used as much as the single function execution unit 141 is uninstalled as in the first embodiment.

  In the fourth embodiment, the installation target is selected from the unit function execution units 141 that are not installed via the function-specific installation status screen. It is good also as a structure which can be selected as an installation object. According to this modification, when the version of the installed single function execution unit 141 is updated in the server 200, the latest version of the single function execution unit 141 can be installed.

  In the above embodiment, when an execution instruction for a function button is input, the performance information is acquired regardless of the single function that is the target of the execution instruction. Instead, the performance information is acquired only for a function whose function is dependent on performance information, for example, a function that depends on whether the device is color-compatible, such as a copy function. It is good also as a structure. Moreover, it is good also as a structure which does not acquire performance information. In such a modification, a copy processing program 141 composed of a color copy processing program and a monochrome copy processing program may be installed even for a device that does not support color.

  Alternatively, when the model list included in the main body installer 121 includes the performance information of each model, and the target device is a color-compatible model, a function button for color and a function button for monochrome are displayed on the entire UI 50. It is good also as a structure which displays. For example, as a function button corresponding to the copy function, a function button for color copy and a function button for monochrome copy may be displayed on the entire UI 50. In such a modification, the color copy processing program and the monochrome copy processing program are downloaded and installed independently of each other.

  In the above embodiment, the performance information is acquired when an execution instruction for the function button is input. However, after the main body program processing is started, the performance information is acquired and stored in the RAM 13 or the like. When the execution instruction is input, the stored performance information may be used.

  In the third embodiment, the method of continuously installing all the single function execution units 141 and the method of sequentially installing them can be selected, but either one may be used. In addition, when all the single function execution units 141 are installed continuously, the single function execution unit 141 is installed after the basic function execution unit 123 is installed, but before the basic function execution unit 123 is installed. Alternatively, all the single function execution units 141 may be installed continuously before the selection screen is displayed and the basic function execution unit 123 is installed.
