Abstract
Abstract Combined computer and communications apparatus is described which is constructed with a two-part casing, the parts ( 1, 2 ) being hinged together. When folded together, the entire unit can act like a mobile phone (FIG. 1 ) and when unfolded (FIG. 2 ) a keyboard ( 5 ) is exposed enabling it to act as a palmtop computer. In accordance with the invention, the keyboard ( 5 ) is folded about a line running substantially perpendicular to the direction of the rows of keys. One casing portion ( 1 ) may have a window ( 4 ) through which a screen ( 3 ) mounted on the other casing portion ( 2 ) may be viewed when the unit is folded.
