A switch conveyor including a modular conveyor belt or mat divided into longitudinal lanes of rollers. All the rollers in a lane are arranged to rotate about axes oriented in a common direction. The rollers in an adjacent lane are arranged to rotate about axes oriented in a different direction. A switch mechanism underlying the conveyor belt along a carryway selectably contacts the bottom side of the belt or mat with bearing surfaces that rotate the rollers in selected lanes along the carryway to propel conveyed articles in one direction or another.

The pulley unit of claim 12 further comprising, a cam portion having a rounded cam surface, wherein the cam portion is located within a wedge-like space. 14. The pulley unit of claim 13, wherein the plurality of spaces are formed in an outer peripheral surface of the inner ring, the spaces being defined by the cam portion, a spring, and the outer ring, and wherein a radial distance between the cam surface and an inner surface of the outer ring decreases in the biasing direction of the spring in order to secure the roller between the cam surface and the inner surface of the outer ring when the one-way clutch is in a locked position. 15. The pulley unit of claim 13, wherein the plurality of spaces are formed in an inner peripheral surface of the outer ring, the spaces being defined by the cam portion, a spring, and the inner ring, and wherein a radial distance between the cam surface and an outer surface of the inner ring decreases in the biasing direction of the spring to secure the roller between the cam surface and the outer surface of the inner ring when the one-way clutch is in a locked position. 16. The pulley unit of claim 12 further comprising, a bearing located between the pulley and the outer ring, the bearing providing additional support for the pulley.
