The present invention relates to an automobile road center line indicating device by using optical transfer including: a light condensing device installed at road center line or border line for condensing light emitted from headlights of an automobile; an optical cable for transferring the light condensed by the light condensing device to a predetermined position ahead from the automobile; and a luminous device for transforming the light transferred along the optical cable into straight-advancing parallel light to notify a driver. having a first end and a second end and including a pair of side rails, each of said side rails having an upper surface, said track defining a plurality of sequential load unit positions, a first of said load unit positions being a loading position proximate said track first end and a last of said load unit positions being an unloading position proximate said track second end; b) a plurality of interconnected carts moveable along said track, said plurality of carts being at least one fewer in number than the number of said load positions, a first of said carts being proximate said track first end and a last of said carts being proximate said track second end, each of said carts being adapted to receive a respective load unit and including a lifting platform and an air bladder positioned beneath said lifting platform, said air bladder being selectively inflatable and deflatable for moving the load unit between a lowered position wherein the load unit rests on said side rail upper surfaces and a raised position wherein the load unit is lifted clear of said side rail upper surfaces; c) a pneumatic cylinder connected between said track and said carts for reciprocally moving said carts along said track between a home position wherein said first cart is in said loading position and a forward position wherein said last cart is in said unloading position; and d) a pneumatic system connected to said cylinder and each said bladder and operable to advance a load unit from said loading position toward said unloading position by cyclically moving the load unit into said raised position, moving said carts into said forward position, moving said load unit into said lowered position, and moving said carts back into said home position beneath the load unit. 9. The conveyor as in claim 8 wherein each of said track side rails includes an inwardly extending flange and each of said carts includes a plurality of wheels, each of said wheels riding on one of said flanges. 10. The conveyor as in claim 8 wherein said pneumatic system includes a sensor mounted on each of said carts, each said sensor being operable in response to a load unit being positioned on the respective cart to actuate a respective cart sensor valve. 11. The conveyor as in claim 10 wherein said pneumatic system further includes an unloading position sensor mounted on said track at said unloading position, said unloading position sensor being operable in response to a load unit being positioned in said unloading position to actuate a respective unloading position sensor valve. 12. The conveyor as in claim 10 wherein said pneumatic system includes a bladder inflation circuit for selectively inflating said air bladders, airflow into said bladder inflation circuit being controlled by a bladder inflation valve which is actuated upon said carts arriving in said home position. 13. The conveyor as in claim 12 wherein said bladder inflation circuit includes a first branch, airflow into said first branch being controlled by said unloading position sensor valve, said first branch being connected to all of said air bladders such that all of said air bladders may be inflated when no load unit is positioned on said track at said unloading position. 14. The conveyor as in claim 13 wherein the one of said cart sensor valves actuated by the one of said sensors on said first cart is a normally closed valve and said bladder inflation circuit further includes a second branch in parallel to said first branch, airflow into said second branch being controlled by said normally closed valve such that no air will flow into said second branch unless a load unit is positioned on said first cart. 15. The conveyor as in claim 14 wherein the rest of said cart sensor valves are normally open valves and said second branch further includes a plurality of parallel legs, airflow through each of said legs being controlled by a respective one of said normally open cart sensor valves, each of said legs being conne
