Abstract
The present invention relates to a solid state bowling pin counter which is designed to replace existing mechanical pin counters. The solid state pin counter uses infrared technology and electro-optics to reliably detect the presence of a bowling pin as the pin travels towards the bowling pin table via the distributor assembly. The solid state pin counter can detect all colors of bowling pins and it works reliably in all ambient light conditions including flashing lights. If power is turned off during the time bowling pins are being fed into the bowling pin table, the memory in the pin counter remembers the pin counter's condition no matter where the bowling pin is on the distributor belt. Thus, when power is turned back on, the bowling pin table is filled with bowling pins as if the power was never turned off.
