ールド構造。 The tuner is a double conversion type tuner in which the printed circuit board containing the circuit that converts the frequency and voltage so that it can receive broadcast radio waves and send them to the amplifier is shielded by a chassis shield case, a shield plate, a front shield lid, and a back shield lid. In the shield lid, the projections provided on one side of each of the front shield lid and the back shield lid are inserted into the holes provided in the chassis shield case, and the other side of each shield lid is inserted into the chassis shield case. Either it is screwed to the case, or a raised cut provided on the side of the chassis shield case is inserted into the through hole of the shield.
The shield structure of the double convergence unit is characterized by being fixed by twisting.
