摘要

The operating panel unit of the MFP modifies the screen layout by adjusting the spacing between the groups of key images of the size variable key, basic keys and application keys when the size of the key image of the size variable key is modified. If it is impossible to display all the key images simultaneously on the screen, the size of the key image is reduced to modify the screen layout. As an alternative, the mode for the application keys is changed from the mode of displaying all the constitutional keys to the mode of the scroll display to change the screen layout. Consequently, the size of a specific operating key can be arbitrarily modified and the layout of other operating keys is automatically modified in a data input device where a touch panel is provided on its display.
