A bar code scanning system for a conveyor system in which a first conveyor (610) and a second conveyor (620) are disposed apart from each other by a small gap region (635). A light emitting device is positioned in the gap (635) underneath a top surface of the first and second conveyors (610, 620), and the light emitting device shines light onto bar code labels on a bottom side of objects as the objects traverse from the first conveyor (610) to the second conveyor (620). A light receiving device is also positioned in the gap (635), and the light receiving device recieves reflected light from the bottom side of the objects due to the light being shined on the objects by the light emitting device. The gap (635) is covered by a glass or plastic plate, so as to allow light to pass substantially therethrough.
