Abstract: In a display device, attached to a plate-type chassis (2) is a PDP (1) having a display screen on which videos are displayed and a circuit board (9) on which a circuit driving the PDP (1) is arranged. The circuit board (9) is shielded with respect to the PDP (1) thanks to the chassis (2), and thus does not receive any unwanted radiation noise radiated by the PDP (1). The display device further includes a back cover (6) and a cabinet (7) each having conductivity. The back cover (6) and the cabinet (7) house therein the PDP (1) and the circuit board (9) attached to the chassis (2). The back cover (6) and the cabinet (7) are both electrically insulated from the chassis (2). Therefore, any unwanted radiation noise from the PDP (1) and the circuit on the circuit board (9) is stopped leaking to the outside.

Abstract: A crushing apparatus is provided for crushing a printed circuit board on which electronic components are mounted into pieces of a size ranging from a few to ten centimeters square and separating some of the components and sheathed wires from the printed circuit board. The crushing apparatus comprises a rotor 3 having a substantially conical or truncated conical projected center 6 mounted at the center of rotation thereof, a plurality of extensions 3a thereof extending from the conical projected center 6 radially and horizontally, and studs 3 and 4 mounted on the extensions 3a thereof. A drive motor 8 is provided for rotating the rotor 3, a cylindrical case 1 accommodates the rotor 3 therein, and a plurality of studs 2 mounted are on the inner side of the cylindrical case 1.
