PREVENTION OF UNDESIRED RADIATION

摘要

PURPOSE:To reduce the undesired radiation by using a conductive cloth obtained by applying a metallic treatment onto the surface of a cloth woven with fibers as a conductor which secures the connection between two blocks where a high frequency impedance is produced to cause the undesired radiation. CONSTITUTION:A conductive cloth 7 means a wide thin film sheet having high flexibility, and the surface of this sheet undergoes an electrical conduction treatment with metallic plating. Then the cloth 7 is electrically connected to a ground 1a of a display part 1 and a ground part 3b of a main body part 3. The width (b) of the cloth 7 is important for prevention of the undesired radiation and can be satisfactorily increased. Thus the grounds of both parts 1 and 3 are electrically connected to each other via a conductor having the large width. Then a high frequency impedance can be reduced between blocks and the undesired radiation can be effectively prevented. Furthermore the conductive sheet has high flexibility and therefore can be put into a small gap. Then the equipment of the sheet can also be miniaturized.
