Page turning apparatus for use with computer system

Abstract

Symbols of a plurality of page turning buttons and one guide display button are displayed on a screen of a computer system. A page turning apparatus for use with a computer system has a screen data table that stores information of page turning buttons for individual pages to be turned and information of pages displayed by the page turning buttons. When one of the page turning buttons is selected by an input unit such as a mouse, the page turning apparatus obtains page information corresponding to the selected page turning button from the screen data table and replaces the current screen page of the computer system with a page corresponding to the obtained page information. In addition, the page turning apparatus has a screen page hierarchical data table corresponding to functions of pages that can be displayed. When a guide display button is selected by the input unit such as the mouse, the page turning apparatus generates a screen page hierarchical chart that hierarchically represents the relation of individual pages based on the screen hierarchical data table, changes the color of a part of the screen page hierarchical chart so as to distinguish the current screen page in the screen page hierarchical chart, and displays the screen page hierarchical chart as a window on the screen of the computer system.
