The image forming apparatus 10 may be a multi-function peripheral (MFP) that may perform functions such as copying, printing, scanning, fax sending/receiving, or e-mail transmitting in one apparatus. Hereinafter, a case where the image forming apparatus 1 is an MFP will be described for the convenience of description; however, the present embodiment is not limited thereto.
The image forming apparatus 1 performs image forming operations such as a scanning operation by using the scanning unit 40, a printing operation by using the printing unit 50, a copying operation by using the copying unit 60, a fax operation by using the fax unit 70, or an e-mail transmission operation by using the network interface unit 30. In addition, in order to perform such image forming operations, operation options corresponding to each of the image forming operations have to be set.
The operation options according to the present embodiment denote detailed operation operations that may be directly applied to perform the image forming functions, for example, the number of sheets to be copied, magnification/reduction ratio, scanning path, e-mail address, and fax number.
The process of setting the operation options as described above are performed by displaying the operation operations to the user through the user interface unit 10, and by inputting setting values of the displayed operation options through the user interface unit 10.
That is, the user interface unit 10 receives information input by the user, or outputs information processed in the image forming apparatus 1 to the user. For example, the user interface unit 10 may include a display unit (not shown) and an input unit (not shown).
In more detail, the user interface unit 10 acquires information from the user via the input unit (not shown) such as a keyboard, a mouse, a touch screen, and a voice recognition. Moreover, the user interface unit 10 includes the display unit (not shown), for example, a display, a liquid crystal display (LCD), or a light emitting diode (LED), displaying visible information in order to report the information to the user.
In the present embodiment, a case where the user inputs the information by using the input unit (not shown) such as a touch screen in the user interface unit 10, will be described as an example for the convenience of description. However, one of ordinary skill in the art would appreciate that the user may input the information by using hardware buttons disposed on the image forming apparatus 1 according to the user interface unit 10 of the present embodiment.
The image forming apparatus 1 may display operation options about the image forming operations through the user interface unit 10. In addition, the image forming apparatus 1 receives the input of the user via the user interface unit 10 such that the operation operations about the image forming functions may be set.
Hierarchical class menus are only displayed on one screen of the user interface unit 10. In addition, detailed operation options for one image forming function are only displayed on one screen of the user interface unit 10 conventionally, and thus detailed operation options for various image forming functions may not be displayed on one screen.
FIGS. 2A and 2B are diagrams showing option screens displayed on the user interface unit 10 according to the conventional art.
Referring to FIG. 2A, menus corresponding to kinds of the image forming functions, for example, copy, fax, scan, etc., are displayed on one screen in the user interface unit 10, and detailed operation options for various image forming functions are not displayed at the same time. In addition, referring to FIG. 2B, in a case of the copying function, for example, operation options for the copying function are only disposed on the user interface unit 10, and thus the user has to transfer or move to other option screens in order to set operation options for other image forming functions such as the scanning, and printing operations.
However, according to the image forming apparatus 1 of the present embodiment, the operation options for various kinds of image forming functions may be set at once while minimizing transferring or moving of the screen in the user interface unit 10. That is, an all-in-one screen, in which operation options for the image forming functions may be displayed together, is provided, and thus the user may easily and rapidly input the operation options in one screen. Hereinafter, operations of the image forming apparatus 1 providing the option screen in which the operation options for various kinds of image forming functions are displayed will be described as follows.

Referring to FIG. 3, the processor 20 includes an option determination unit 210 and a screen generation unit 220. The processor 20 may be realized by an array of a plurality of logic gates, or may be realized by a combination of a universal microprocessor and a memory storing a program that is executed in the microprocessor. Otherwise, the processor 20 may be realized as another type of hardware.
The option determination unit 210 determines at least one operation option corresponding to each of the two or more image forming functions supported by the image forming apparatus 1. For example, the image forming functions of the image forming apparatus 1 of the present embodiment include at least two or more among the printing function, the scanning function, the copying function, the fax function, and the e-mail transmission.
For example, the option determination unit 210 determines at least one operation option among the operation options for the printing function, for example, the number of sheets to be printed, a size of a printing medium, a printing ratio, and a printing page setting. In addition, the option determination unit 210 determines at least one operation option among the operation options for the copying function, for example, the number of sheets to be printed and a size of the medium. Moreover, the option determination unit 210 determines at least one operation option among the operation options for the scanning function, for example, fax number and a size of fax medium.
That is, the option determination unit 210 determines at least one operation option corresponding to each of the two or more image forming functions, that is, the printing, the copying, and the scanning functions.
According to an embodiment, the option determination unit 210 may determine at least one operation option based on the kinds of operation options that have to be input by the user in order to perform the image forming functions.
In more detail, if fax number of a counterpart, to which a fax is to be transmitted through the fax unit 70, is not input through the user interface unit 10, the image forming apparatus 1 may not perform the fax function. In addition, if a path for storing or transmitting a result of scanning operation by the scanning unit 40 is not input through the user interface unit 10, the image forming apparatus 1 may not perform the scanning function.
Therefore, the option determination unit 210 may determine the operation options in consideration of the options that are essential for performing the each of the image forming functions.
According to an embodiment, the option determination unit 210 may determine at least one operation option in consideration of a size of one screen of the user interface unit 10. If too many operation options for each of the two or more image forming functions are determined, the operation options may not be displayed in the same screen, or may be displayed too small to be recognized.
The screen generation unit 220 generates an option screen, in which regions for setting the operation operations determined with respect to each of the two or more image forming functions are displayed. This will be described in more detail with reference to FIG. 4.
FIG. 4 is a diagram showing an example of the option screen generated by the screen generation unit 220 according to the embodiment of the present invention. When the operation options with respect to the copying function, the fax function, and the scanning function are determined in the option determination unit 210, the screen generation unit 220 generates the option screen shown in FIG. 4, in which a region 401 for setting the operation options determined with respect to the copying function, a region 402 for setting the operation options determined with respect to the fax function, and a region 403 for setting the operation options determined with respect to the scanning function are displayed in the same screen.

In operation S602, when the user requests to operate the all-in-one application program, the processor 20 controls the user interface 10 to display the option screen of FIG. 4.
In operation S603, the user interface unit 10 receives fax number from the user in a case where the region 402 regarding the fax function is activated.
In operation S604, the user interface unit 10 receives the number of sheets to be copied from the user in a case where the region 401 regarding the copying function is activated.
As described above, according to the image forming apparatus 1 of the present embodiment, the operation options with respect to various kinds of image forming functions may be set in the same screen of the user interface unit 10 without moving or changing the screen.
FIG. 7 is a detailed block diagram of the user interface unit 10 and the processor 20 according to the present embodiment. Referring to FIG. 7, the processor 20 further includes an option edit unit 230 and a controller 240 in addition to the structure of the processor 20 shown in FIG. 3.
The option edit unit 230 edits the operation options that will be arranged in the option screen according to the input of the user. That is, when the user directly selects the operation options that will be displayed in the option screen through the user interface unit 10, the option edit unit 230 edits the operation options based on the input of the user. In addition, the option determination unit 210 determines at least one operation option based on the edition result.
FIG. 8 is a diagram showing an option edit screen according to the embodiment of the present invention. The user may edits the operation options with respect to each of the copying, fax, and the scanning functions through the option edit screen shown in FIG. 8. The option edit unit 230 edits the operation options that will be arranged in the option screen according to the operation options selected by the user.
Referring to FIG. 7 again, when the input of the user about the operation options is received through the option screen displayed on the user interface unit 10, the controller 240 controls the image forming functions to be performed based on the input of the user with respect to the operation options. That is, the controller 240 controls the printing function, the copying function, the scanning function, the fax function, or the e-mail transmission function to be performed according to the set operation options.
When the controller 240 is asked to perform the image forming function in a state where the essential operation options are not set, the user interface unit 10 displays an error message notifying the user that the essential operation options are not set yet.
For example, if the fax number is two-digits or less, the user interface unit 10 displays a message such as “Enter a Fax No with Minimum 2 digits[0-9, * or #]”.
When the operation options about the plurality of image forming functions are input and the plurality of image forming functions are controlled to be performed, if one image forming function is not performed, the controller 240 may control another image forming function to be performed first.
If a cause making one of the image forming functions not to be performed is that the essential operation options are not input, the controller 240 controls so that the essential operation options are set by showing a pop-up window or changing the option screen and the image forming functions are performed.
FIG. 9 is a diagram showing a pop-up window 901 relating to the essential operation options displayed on the user interface unit 10 according to the embodiment of the present invention. Referring to FIG. 9, when the controller 240 performs the scanning function of a document, for example, the user interface unit 10 displays a pop-up window for asking the user whether dual surfaces are to be scanned.
As described above, according to the present embodiment, the user interface unit 10 may set the operation operations relating to various kinds of image forming functions at the same time without changing the screen. On the other hand, the image forming apparatus 1 may execute a work flow operation for performing the various kinds of image forming functions at the same time.
In the option screen of FIG. 4, the button 405 for selecting the activation of each of the two or more image forming functions, and the button 406 for executing the work flow operation are displayed.
If the user pushes the button 405 for activating the copying function and the scanning function and the button 406 for executing the work flow operation in the option screen of FIG. 4, the copying function and the scanning function are performed in the work flow operation.
In more detail, when the button 406 for executing the work flow operation is input after setting all the operation options in the region 401 regarding the copying function and the region 403 regarding the scanning function, the controller 240 controls the copying function and the scanning function in the work flow operation.
At this time, the controller 240 controls overlapping image forming operations to be performed once in the two or more image forming functions, during the work-flow operation is performed. That is, in a case where an operation of converting the document into an image file is performed in both of the copying function and the scanning function, the controller 240 controls the operation of converting the document into the image file to be performed once.
FIG. 10 is a flowchart illustrating a method of performing the copying function and the scanning function in the work flow operation based on the operation options input through the user interface unit 10 according to the embodiment of the present invention.
