- a casing having a planar display unit with at least one planar display screen disposed on a first side of the casing;
at least one manipulation region for operation by a user, said manipulation region being provided at a border zone of the display unit in such a way that the user can perform operating actions with one or more fingers of one hand; and
at least one actuatable operating element that is arranged within the manipulation region on a second side of the casing that faces in a direction different than the first side, wherein actuation of the at least one operating element individually or in combination initiates at least one of leafing-through functions to navigate document content displayed on the display screen, scrolling functions to navigate document content displayed on the display screen, and providing functions for selection menus;
wherein at least one said operating element is adapted to actuate, on selection in an initial state, a specific first functionality, and, immediately after actuating the first functionality, is automatically re-programmed to be adapted to actuate, in a next state, a selected second functionality;
wherein the first side of the casing is a front side and the second side of the casing is a rear side;
wherein at least a portion of the display screen within the manipulation region includes a touch-sensitive touchscreen;

Abstract
A digital book comprising a casing which is adapted to be folded open and shut like a book and which has at least one folding axis (A), a main part (1) and at least one secondary part (2), said parts together forming a book back part (BR). A display unit consists of at least two parts and is arranged in such a way that when the casing is folded out, the main part (1) and the at least one secondary part (2) are each presented to the user with at least one screen each, like pages of a book, for looking at or optionally, for working on as required. The digital book contains a control unit with means for receiving, storing, processing and reproducing information, and at least one operating unit (6) with operating elements for using the digital book as a device for receiving/processing/reproducing information. Furthermore, there is provided a supply unit (VE) which is designed such that it has a receiving opening (VE′) and a guide and supply pin (7), by means of which the digital book can be plugged in when the casing is folded shut, for inputting and outputting information, for supplying energy and for storing the digital book.
