Abstract
The optical ball sensor consists of an optical sensor consisting of a light emitter and light detector mounted on a printed circuit board. Light from the emitter is transmitted through a light pipe across the path of travel of the ball and through another light pipe back to the detector. When a rolling pinball interrupts the light beam, a signal is delivered to the game microprocessor. The microprocessor can be programmed to respond to the signal in any number of ways, for example, the microprocessor can score points, initiate other play features and the like.
