ABSTRACT:
The chassis of an information recording disk player, carrying various mechanisms is made of a noncontractive synthetic resin. The chassis comprises a flat body and peripheral walls integrally formed with the flat body so that the flat body is reinforced providing sufficient rigidity comparable to a conventional diecasting-made chassis. A casing which encloses the chassis comprises front, rear, top and bottom plates. The front and rear plates function as stands of an intermediate product for holding horizontally the chassis so that assembly and adjustment are readily performed. The casing is made of a conductive material to prevent spurious irradiation of electromagnetic waves from the pickup assembly of the player.
