摘要: A bar code scanning system for a conveyor in which first and second are disposed apart from each other by small gap region. light emitting device is positioned the underneath top surface of conveyors, shines onto labels on bottom side objects as traverse to conveyor. receiving also gap, receives reflected due being shined device. The covered glass or plastic plate, so allow pass substantially therethrough.
