ABSTRACT:
A playing field board for pinball game machines which is assembled with a playing surface thereof inclined, and along the inclined playing surface of which a round ball rolls downwardly by gravity and is driven upwardly by means of kicker apparatus, is made of a steel sheet and a transparent plastic layer of synthetic resin, e.g. urethane, disposed on the surface of the steel sheet. Between the steel sheet and the plastic layer of synthetic resin comprising the playing field, a buffer such as paper sheeting is interposed to dampen the noises made by a ball rolling along the playing surface of the playing field. Such paper sheeting can be in the form of a sandwich of metal foil between two paper sheets. The steel sheet contains a hole which is located beneath the transparent layer of plastic, and the hole is filled by a transparent plug. A metal hole is welded to the underside of the steel sheet. The holder supports an electric light bulb which shines upward through the transparent layer of plastic.
