Belt Patents (Class 235/71R)
  • Patent number: 4651998
    Abstract: The invention relates to a projectile target game of the dart type which has individual player score keeping apparatus that includes a pair of nonrotatable shafts around which are loosely carried continuous belts which have an opaque background through which transparent numbers have been formed. Each digit of a number has a width substantially greater than the digits height. The continuous belt passes between a light source and a unidirectional magnifying lens which magnifies only the height dimension of the number's digits. The continuous belt is provided with score advance openings that are exposed via a slot in the face of the game that supports the target. The score advance openings are adjacent the transparent numbers such that a score may be made to appear in the magnifying lens. The target of the dart game is a dart board which has a unique bullseye target deflection detection mechanism.
