Information input/output apparatus.

摘要

There is an information input/output apparatus for displaying information to a display such as a LCD by instructing and operating an input device such as a transparent flat touch panel arranged on the display. The apparatus has a display controller for allowing the display to display a display area pattern for instructing that information which was input from the input device is displayed by the display on a page unit basis. A first pattern to roughly instruct a page, a second pattern to instruct the pages before and after the present page position, and a third pattern to instruct a page by directly inputting a page number are displayed in the display area pattern. The display controller discriminates which one of the first, second, and third patterns is indicated by the instruction operating position of the input device and displays the information of the corresponding page to the display. The document information can be displayed on a display screen on a page unit basis and the operator can freely instruct and display an arbitrary page through the input device.
