構造。[Scope of Claim for Utility Model Registration] (1) A circuit block that requires electromagnetic shielding and a circuit block that requires heat dissipation on a printed wiring board installed in the frame of a chassis used for electronic equipment. A first metal plate is formed adjacent to each other and has a length extending from one end to the other end of the printed wiring board, and the first metal plate passes between the circuit blocks and extends from one end to the other end of the printed wiring board. A metal plate is placed upright on the board, and a substantially U-shaped second metal plate and a third metal plate are respectively provided, and the side surface of the second metal plate is aligned with the side surface of the first metal plate. The third metal plate is attached to one side of the frame body, the side surface of the third metal plate is attached to the opposite side of the first metal plate, and a metal top plate is provided that covers the entire top surface of the frame body. The first and second boards are erected on the printed wiring board.
and a chassis structure that is attached to cover the upper end surface of the third metal plate. (2) The chassis structure according to claim (1), wherein the second metal plate and the third metal plate are each substantially L-shaped.
