Abstract

IN A CUTOUT PORTION (3C,3D) OF A SIDE PLATE (3,4,5,6) OF A SHIELDING CASE (1), A PORTION OF THE SIDE PLATE IS CUT AND RAISED IN PARALLEL WITH AN END FACE TO FORM EARTH TERMINALS (7A,7B). ACCORDINGLY, FLAT SURFACES OF THE EARTH TERMINALS (19) AND FLAT SURFACES OF CIRCUIT TERMINALS FORMED ON A PRINTED CIRCUIT BOARD (18) CAN BE POSITIONED OPPOSEDLY IN PARALLEL WITH EACH OTHER AND AT A SHORT DISTANCE, AND CAPACITORS (21) CAN BE CONNECTED TO THE CIRCUIT TERMINALS (19) AT POSITIONS OF THE SHORTEST DISTANCE FROM THOSE CIRCUIT TERMINALS THROUGH CIRCUIT PATTERNS (10b) FORMED ON A MOTHER BOARD (10) OF A SET SYSTEM. THEREFORE, EVEN IF AN UNNECESSARY SIGNAL IS CONTAINED IN A CIRCUIT OF A HIGH-FREQUENCY DEVICE, THE SIGNAL CAN BE SURELY CONDUCTED TO GROUND THROUGH THE CAPACITORS (21).(FIG. 1)
