ABSTRACT:
A protective cover for keyboard machines consisting of a transparent hood affixable to the machine housing and open at one side to admit the operator's hand, including a panel generally parallel to the keyboard face and spaced apart therefrom by a distance sufficient to allow normal hand and finger movements by the operator, but too close to permit any appreciable whole-hand movements normally to the keyboard whereby the operator cannot strike the keyboard buttons with excessive force which can damage the machine. The hood prevents access of spilled liquids, paper clips, coins, bits of metal or the like to the keyboard. Such foreign matter may find its way to the interior of the machine through slots and other openings of the keyboard, and cause malfunctioning thereof.
