(1) ABSTRACT A portable device for the electronic display of reading and reference material to allow for an alternative to books and other paper based presentation formats. Provides the capability to access and retrieve text, data and graphics from previously encoded units of computer addressable storage media, and transmit these data to an integrated monochrome and/or colour video screen. The data resides on small pre-prepared units of high volume data storage media (eg. 3 1/2 inch computer diskettes), which are individually loaded into the device as required. User controlled functions allow pre-defined groups of data, i.e. pages, to be accessed and displayed sequentially forward or reverse, by page number, or by the specific page which was last displayed on individual data storage units through an electronic placemark function. Display functions include a capability to increase the size of the data characters on the viewscreen, to allow the device to be used by the visually impaired, and controls for adjustment of the visibility attributes (eg. resolution, contrast, tint, etc.). Protection and support is provided by acombination cover and adjustable stand. The device also incorporates a carryinghandle to enhance portability. This invention is distinguished from and improves upon desktop or larger computers by: read only, non-programmable and non-programming functionality; simplicity of controls and operation; and portability. It is distinguished from and improves upon portable computers by: read only, non-programmable and non-programming functionality; simplicity of controls and operation; and lower cost. This invention is distinguished from and improves upon print and paper, or other non-electronic text and data output methods by: providing the capability of access to data residing on storage mediawhich has far less volume and weight per unit of data durability; text and data size adjustment capability; internal illumination; user convenience; and potential for the reduction of environmentally hazardous pulp and paper requirements.
