ABSTRACT:
A system for detecting pins of ten pin bowling apparatus including a lens for receiving light reflected from standing pins and a linear light sensitive array for receiving light from the lens. A microcontroller is provided for controlling operation of the system and serves to provide a serial output corresponding to the level of light reflected from said pins. A housing is mounted between a pair of lanes, the housing carrying the lens and array which is adjustably mounted relative to the lens. A visual display may be provided to enable the array to be set up to receive similar light signals from each lane.
