  • Patent number: 5931731
    Abstract: Disclosed is an optical coin counting system for use in gaming machines such as video poker machines and slot machines. One disclosed system includes an optical detector including a light source and a light detector, a deflection arm which deflects when a coin passes over it, a shaft attached to the deflection arm such that the shaft rotates when the deflection arm deflects, an optic flag attached to the shaft at a location remote from the deflection arm such that when the coin causes the deflection arm to deflect, the optic flag moves with respect to the light detector to cause a change in light intensity detected by the detector, and an opaque barrier disposed substantially about the optic flag such that substantially all light proximate the deflection arm is blocked from reaching the optical detector. The shaft may pass through the opaque barrier.
