The setting acquiring unit 18b acquires the software key setting 17c. The software key display 18c displays the soft numeric keypad 40 on the touch panel 11 corresponding to the software key setting 17c acquired by the setting acquiring unit 18b.

Next, a description will be given of the performance of the MFP 10.

First, a description will be given of the performance of the MFP 10 when the soft numeric keypad 40 is displayed.

FIG. 6 illustrates a performance of the MFP 10 in a case where the soft numeric keypad 40 is displayed.

When a user instructs the activation of the Java application 17b via the touch panel 11, the control unit 18 activates the Java application 17b to start the performance illustrated in FIG. 6.

After the Java application 17b is activated, the Java application 17b displays a specific screen such as the server setting screen 30 illustrated in FIG. 3 to FIG. 5 for the Java application 17b itself on the touch panel 11. Then, the setting acquiring unit 18b of the Java application 17b requests the Java Platform 17a to acquire the software key setting 17c as illustrated in FIG. 6 (Step S101).

When the Java Platform 17a receives the request to acquire the software key setting 17c from the setting acquiring unit 18b in Step S101, the Java Platform 17a requests the panel control unit 18a to acquire the software key setting 17c (Step S102).

When the panel control unit 18a receives the request to acquire the software key setting 17c from the Java Platform 17a in Step S102, the panel control unit 18a acquires the software key setting 17c from the storage unit 17. Then, the panel control unit 18a notifies the Java Platform 17a of the software key setting 17c acquired from the storage unit 17 (Step S103).

When the Java Platform 17a receives the notification of the software key setting 17c from the panel control unit 18a in Step S103, the Java Platform 17a notifies the setting acquiring unit 18b of the Java application 17b of the notified software key setting 17c (Step S104).

When the set values of the “initial display setting” and the “hardware key setting,” which are the items of the software key setting 17c notified from the Java Platform 17a to the setting acquiring unit 18b in Step S104, are “On” and “Off” respectively, the software key display 18c of the Java application 17b requests the Java Platform 17a to display the soft numeric keypad 40 on the touch panel 11 (Step S111). Here, the software key display 18c includes the set values of the “arrangement type setting” and the “display position setting,” which are the items of the software key setting 17c notified from the Java Platform 17a to the setting acquiring unit 18b in Step S104, and an application ID as identification information of the Java application 17b itself in the request in Step S111.

When the set value of the “initial display setting,” which is the item of the software key setting 17c notified from the Java Platform 17a to the setting acquiring unit 18b in Step S104, is “Off,” the software key display 18c does not immediately execute the process of Step S111. The software key display 18c executes the process of Step S111 at a specific timing. Here, the specific timing includes a timing when operations that specifies the text box such as the text boxes 31 and 32 on the server setting screen 30 illustrated in FIG. 3 to FIG. 5, that is, dedicated operations to display the soft numeric keypad 40 on the touch panel 11 are input to the touch panel 11, and a timing when the soft numeric keypad 40 is preferred to be displayed on the touch panel 11, for example, a timing when a specific screen including the text box is displayed on the touch panel 11. The software key display 18c may determine the timing when the soft numeric keypad 40 is preferred to be displayed on the touch panel 11 corresponding to the operation input to the touch panel 11.

When the set value of the “hardware key setting,” which is the item of the software key setting 17c notified from the Java Platform 17a to the setting acquiring unit 18b in Step S104, is “On,” the software key display 18c does not execute the process of Step S111.

When the Java Platform 17a receives the request to display the soft numeric keypad 40 on the touch panel 11 from the software key display 18c in Step S111, the Java Platform 17a requests the panel control unit 18a to display the soft numeric keypad 40 on the touch panel 11 (Step S112). Here, the Java Platform 17a includes the set values and the application ID that are notified from the software key display 18c in Step S111 in the request in Step S112.

When the panel control unit 18a receives the request to display the soft numeric keypad 40 on the touch panel 11 from the Java Platform 17a in Step S112, the panel control unit 18a displays the soft numeric keypad 40 on the touch panel 11 corresponding to the set values notified from the Java Platform 17a in Step S112 (Step S113). Then, the panel control unit 18a notifies the Java Platform 17a of the display of the soft numeric keypad 40 on the touch panel 11 (Step S114).

When the Java Platform 17a receives the notification of the display of the soft numeric keypad 40 on the touch panel 11 from the panel control unit 18a in Step S114, the Java Platform 17a notifies the software key display 18c of the Java application 17b of the display of the soft numeric keypad 40 on the touch panel 11 (Step S115).

Next, a description will be given of a performance of the MFP 10 when the MFP 10 executes a performance corresponding to an operation to the soft numeric keypad 40 displayed on the touch panel 11.

FIG. 7 illustrates a performance of the MFP 10 in a case where the MFP 10 executes a performance corresponding to an operation to the soft numeric keypad displayed 40 on the touch panel 11.

When an operation to the soft numeric keypad displayed 40 on the touch panel 11 is input on the touch panel 11, as illustrated in FIG. 7, the software key display 18c of the Java application 17b requests the Java Platform 17a to execute the performance corresponding to the operation to the soft numeric keypad 40 (Step S121). Here, the software key display 18c includes an application ID of the Java application 17b itself in the request in Step S121.

The performance corresponding to the operation to the soft numeric keypad 40 includes a performance that accepts the input corresponding to the operated key 41 by the operation to the various keys 41 of the soft numeric keypad 40, a performance that terminates the display of the soft numeric keypad 40 by the operation to the button 42 of the soft numeric keypad 40, and a performance that moves the position of the soft numeric keypad 40 on the touch panel 11 corresponding to the operation to the soft numeric keypad 40. Relating to the performance to move the position of the soft numeric keypad 40 on the touch panel 11, the software key display 18c executes the process of Step S121 only when the set value of the “arrangement type setting” as the item of the software key setting 17c is the “Floating layout.”

When the Java Platform 17a receives the request to execute the performance corresponding to the operation to the soft numeric keypad 40 from the software key display 18c in Step S121, the Java Platform 17a requests the panel control unit 18a to execute the performance corresponding to the operation to the soft numeric keypad 40 (Step S122). Here, the Java Platform 17a includes the application ID notified from the software key display 18c in Step S121 in the request in Step S122.

When the panel control unit 18a receives the request to execute the performance corresponding to the operation to the soft numeric keypad 40 from the Java Platform 17a in Step S122, the panel control unit 18a executes the performance required from the Java Platform 17a in Step S122 to the soft numeric keypad 40 that is associated with the application ID notified from the Java Platform 17a in Step S122 (Step S123). Here, the panel control unit 18a executes the process in Step S123 only to the soft numeric keypad 40 specified by the application ID. Accordingly, the panel control unit 18a can prevent the soft numeric keypad 40 associated with the application ID from performed by the software key display 18c of the Java application 17b other than the Java application 17b specified by the application ID that is included in the request to execute the performance corresponding to the operation to the soft numeric keypad 40.

When the panel control unit 18a terminates the display of the soft numeric keypad 40, the panel control unit 18a stores the final display position of the soft numeric keypad 40.

After the process of Step S123, the panel control unit 18a notifies the Java Platform 17a of the execution of the performance corresponding to the operation to the soft numeric keypad 40 (Step S124).

When the Java Platform 17a receives the notification of the execution of the performance corresponding to the operation to the soft numeric keypad 40 from the panel control unit 18a in Step S124, the Java Platform 17a notifies the software key display 18c of the Java application 17b of the execution of the performance corresponding to the operation to the soft numeric keypad 40 (Step S125).

As described above, the MFP 10 displays the soft numeric keypad 40 on the touch panel 11 at the timing corresponding to the set value of the “initial display setting” as the item of the software key setting 17c (Step S113). This eliminates the necessity of a dedicated operation for only displaying the soft numeric keypad 40 on the touch panel 11 to improve the operability of the soft numeric keypad 40.

When the set value of the “initial display setting” as the item of the software key setting 17c is “On,” the MFP 10 displays the soft numeric keypad 40 on the touch panel 11 at the timing of the activation of the Java application 17b. This eliminates the necessity of a dedicated operation for only displaying the soft numeric keypad 40 on the touch panel 11 to improve the operability of the soft numeric keypad 40.

When the set value of the “initial display setting” as the item of the software key setting 17c is “Off,” the MFP 10 displays the soft numeric keypad 40 on the touch panel 11 at the specific timing other than the timing of the activation of the Java application 17b. This eliminates the necessity of a dedicated operation for only displaying the soft numeric keypad 40 on the touch panel 11 to improve the operability of the soft numeric keypad 40.

The MFP 10 displays the soft numeric keypad 40 on the touch panel 11 in the arrangement corresponding to the set values of the “arrangement type setting” and the “display position setting” as the item of the software key setting 17c. This ensures to improve the operability of the soft numeric keypad 40.

The MFP 10 does not display the soft numeric keypad 40 on the touch panel 11 when the numeric keypad 19 as the hardware keyboard is installed on the interface 16, and displays the soft numeric keypad 40 on the touch panel 11 only when the set value of the “hardware key setting” as the item of the software key setting 17c indicates the numeric keypad 19 not to be installed. This ensures to improve the operability.

While the MFP 10 employs the numeric keypad as a keyboard according to the disclosure in the embodiment, a keyboard other than the numeric keypad may be employed.

While the electronic device of the disclosure is the MFP in the embodiment, it may be an image forming apparatus other than the MFP, such as a printer-only machine, a scanner-only machine, a copy-only machine, and a FAX-only machine, and may be an electronic device other than the image forming apparatus, such as a Personal Computer (PC).
