  • Patent number: 4235438
    Abstract: The present invention provides a spinning target which is accurately responsive to the force of impact of a pinball on the target. A generally flat target element is suspended above the playfield so that it is rotatable about an axis parallel to the playfield and sufficiently above the field so that the pinball can pass below when the target element is in a horizontal configuration. The target element has a principal axis of inertia generally coincident with the axis of rotation of the target element. The target element is biased so that it is maintained in a vertical configuration until impacted by the pinball. A pair of weights which have a mass density relatively greater than the mass density of the target element are embedded in the target element in its respective extremities. The weights are symmetrically disposed relative to and remote from the principal axis of the target element.
