Abstract
An electronic bookmark device that can perform multiple functions. The device has a display housing and a thin keypad. The display housing and keypad are sized and connected so that the display housing can rest on the edges of the pages of a book while the keypad is placed between two pages of a closed book. The keys of the keypad are incorporated onto the surface of the keypad such that they do not raise above the general surface of the keypad. The keys of the keypad include multiple function keys that select among dictionary, clock, calculator, schedule/alarm and help features. Additional keys are used for data input including cursor keys, a QWERTY arrangement of alphanumeric keys, and auxiliary keys. Several keys serve dual purposes for use with the various functions of the device.
