Abstract
Abstract The invention relates to a hand-held computer comprising a peripheral frame (10) which contains all the connections and in which cards are removably plugged. A flat display (21), mounted on said frame, is topped by a transparent plate (22) which forms a matrix of touch-sensitive areas or points. The matrix is also mounted on the frame (10). The screen and the plate occupy the maximum of the upper surface of the casing and are electrically connected to the other circuits of the computer by contact with the frame on which they are mounted. The computer may be provided with phoneme recognition means, with hand-writing recognition means or with TV or radio receiving means by insertion of appropriate cards.
