In order to display, with good visibility, meta-information related to an icon selected by the user, out of a plurality of icons list-displayed on the display screen while effectively utilizing resources related to the display screen, the main control section 11 is constructed so as to include: a selected-information obtaining section 71 obtaining selected information when an icon that fits an intent of a user, out of a plurality of icons list-displayed on the display screen, is selected; a meta-information storing section 76 storing each meta-information related to each icon, said meta-information being associated with each of a plurality of icons; and a display control section 77 reading out the meta-information related to the selected icon based on the selected information obtained in the selected-information obtaining section 71 and a stored content of the meta-information storing section 76, and also controlling to display, instead of unselected icons other than the selected icon, the meta-information related to the read-out icon in an area on the display screen on which the unselected icons have been displayed. The meta-information related to the icon is a concept that encompasses attribute information 73 and function information 75 related to the icon. Of the two, the attribute information 73 related to the icon is bibliographic information of a data file corresponding to the icon, for example, and in the embodiment of the present invention, examples thereof may include a title name of the relevant data file, a creator name thereof, an administrator name thereof, a company (department) name of a user thereof, and other comments thereof (for example, meta-information whether this information is classified information, and if so, what level of confidentiality?, etc.). On the other hand, the function information 75 related to the icon is operation or setting information for utilizing a function of a data file corresponding to the icon, for example, and in the embodiment of the present invention, examples thereof may include items related to print, transmit, copy, move, or delete, etc.

Subsequently, an operation of the image forming apparatus mounted thereon with the information display device according to the embodiment of the present invention is described with reference to FIG. 3 and FIG. 4.

As an assumption, it should be noted that the image forming apparatus is placed in a state that a certain user uses a document box function to list-display images of a plurality of icons on the display screen.

At this time, when the icon that fits the intent of a user, out of a plurality of icons list-displayed on the display screen, is touched by a user's finger, the selected information is directed at the selected-information obtaining section 71 via the touch panel section 53 (step S11).

In response thereto, the display control section 77 highlights an icon 79 selected at step S11 (see FIG. 4a) in a color different from those of the other icons, for example, so that the icon can be distinguished from the other icons (step S12). Along with this highlight or instead of this highlight, the display control section 77 may adopt a configuration to impart a checkbox corresponding to the selected icon with a checkmark (see FIG. 4a).

Subsequently, when the icon 79 selected at step S11 is touched again by the user's finger, the selected information is directed at the selected-information obtaining section 71 via the touch panel section 53 (step S13).

In response thereto, based on the selected information related to the icon 79 touched again at step S13 (see FIG. 4b) and the stored content of the meta-information storing section 76, the display control section 77 reads out each of the meta-information (the attribute information 73 and the function information 75) related to the selected icon (step S14), and also controls to display, instead of the unselected icons other than the selected icon 79, the attribute information 73 and the function information 75 (see FIG. 4c) related to the icons read out at step S14 in a space 81 (see FIG. 4c) equivalent to two icons which have been a display area on the display screen and in which the unselected icons have been displayed until immediately therebefore (see FIG. 4c) (step S15).

Subsequently, the display control section 77 sets a predetermined time period (a time period that can be appropriately set and changed by the user, such as for three seconds, for example) as a set value for a count down timer (not shown) housed in the main control section 11, and also monitors whether the timer is timed up (step S16). When it is determined that the count down timer is timed up during this monitoring (see “YES” at step S16), the display control section 77 restores an information display content on the display screen to the original state (step S17). More specifically, the display control section 77 list-displays the unselected icons that have been displayed until immediately before the meta-information has been displayed, instead of a parallel display of the meta-information related to step S15 (see FIG. 4a), and thereafter, ends a series of processes.

As described above, along with selecting the icon that fits the intent of a user, in the space 81 equivalent to two icons, i.e., the display area of the unselected icons, said display area not being required to display thereof any longer, the meta-information (the attribute information 73 and the function information 75) related to the icon 79 read out at step S14 is dynamically switching-displayed. Therefore, according to the information display device according to the embodiment of the present invention, out of a plurality of icons list-displayed on the display screen, the meta-information (attribute information 73 and the function information 75) related to the icon 79 selected by the user can be displayed with good visibility while utilizing effectively the resources related to the display screen.

The user who visually recognizes the attribute information 73 out of the meta-information related to the icon 79 becomes able to grasp the overview of the data file related to the icon 79 through, as bibliographical information of the data file corresponding to the icon 79, for example, a title name (in the embodiment, “document_—1234”), a creator name (in the embodiment, “Taro Osaka”), an administer name (in the embodiment, “Hanako Mita”), a company (department) name of a user (in the embodiment, “ABC Corporation”), and other comments (for example, attribute information whether this information is classified information, and if so, what level of confidentiality?, etc). As a result, upon searching a document that fits the intent of a user out of the document box, the user can significantly improve the workability.

Further, the user who visually recognizes the function information 75 out of the meta-information related to the icon 79 becomes able to improve an information processing efficiency of the data file related to the icon 79 through selective utilization of the function items related to print, transmit, copy, move, or delete, and so on, for example, as the operation or setting information for utilizing a function of the data file corresponding to the icon 79. As a result, upon searching a document that fits the intent of a user out of the document box so as to apply a required information process to the searched document, the user can significantly improve the workability.

Moreover, according to the information display device according to the embodiment of the present invention, it is possible to expect chained synergy resulting from an effective utilization such as a display screen space generated as a result of implementing the effective utilization of resources related to the display screen being assigned to an extension function, used to increase the number of icons that can be list-displayed, and so on.

According to the information display device according to the embodiment of the present invention, as an operation for dynamically switching-displaying the attribute information 73 and the function information 75 related to the icon 79, a very simple operation that is to select the icon is adopted. Thereby, any person can operate intuitively and an excellent information display function can be immediately enjoyed.

According to the image forming apparatus mounted thereon with the information display device according to the present invention, at the user's operation instruction applied via the information display device, the information processing operation according to the operation instruction is executed. Thus, the user can apply the operation instruction while enjoying an excellent information display function with intuitiveness and high operability.

The present invention may adopt a configuration to impart the display control section with a function of scroll-displaying (see step S15-1 in FIG. 5), according to the intent of a user, the meta-information (the attribute information or the function information) related to the read-out icon, instead of the unselected icons other than the selected icon, in the area on the display screen on which the unselected icons have been displayed.

The present invention may also adopt a configuration to impart the display control section with a function of sequentially next-page displaying (see step S15-2 in FIG. 5), according to the intent of a user, the meta-information (the attribute information or the function information) related to the read-out icon, instead of the unselected icons other than the selected icon, in the area on the display screen on which the unselected icons have been displayed.

Further, along with the touching again of the icon at step S13, the display control section 77 may adopt a configuration in which a display manner of the attribute information 73 or the function information 75 related to the icon read out at step S14 is changed step by step and displayed. In this case, it may be possible to configure to change the displayed content step by step such that at the time of touching again the icon at step S13, the attribute information 73 related to the icon is displayed, and further, at the time of touching once again the icon, the function information 75 is displayed instead of the attribute information 73 related to the icon or along with the attribute information 73 related to the icon, for example.

The present invention should not be restricted to the aforementioned embodiment and can be modified appropriately without departing from the gist or technical idea of the present invention understood entirely from the claims and the specification. Information display devices or image forming apparatuses with such modifications are also to fall within the technical scope of the present invention.

That is, for example, an example in which the attribute information 73 and the function information 75 related to the icon 79 read out at step S14 are dynamically switching-displayed in the space 81 equivalent to the two icons, i.e., the display area of the unselected icons, said display area not being required to display thereof, along with the touching of the icon that fits the intent of a user is described in the embodiment of the present invention. However, the present invention is not restricted to the embodiment. That is, the “selection of the icon” for use in the present invention is a concept that encompasses not only touching the icon that fits the intent of a user but also an operation for placing a cursor over an area corresponding to the icon that fits the intent of a user via an appropriate operation section such as a mouse, a slide pad, and a track ball, for example. Therefore, an implementation in which along with the operation for placing a cursor over an area corresponding to the icon that fits the intent of a user, the information display manner is dynamically switching-displayed is also included in the technological range of the present invention.

Finally, as a matter of course, the information display device according to the present invention is not restricted to the application to the image forming apparatus, and can be applied to and incorporated in any information apparatus having a user interface of a mode in which a required icon, out of a plurality of icons list-displayed on the display screen, is selected by the user.
