         3 . The IC package feeder as claimed in  claim 2 , wherein said platform comprises a bottom board, said bottom board having a first sliding groove and a second sliding groove arranged in parallel on a top side near a rear side thereof and transversely extended two opposite lateral sides of said bottom board, two sliding rails respectively slidably mounted in said first sliding groove and said second sliding groove, a top board mounted on said bottom board above the sliding rails in the first sliding groove and second sliding groove of said bottom board, said top board having a plurality of transverse slots corresponding to the first and second sliding grooves of said bottom board; said movable rails of said material delivery tube path unit each have two ends respectively connected to the first and second sliding rails in said first sliding groove and said second sliding groove by screws being inserted through the transverse slots of said top board; said fixed rails mounted on the top board.  
     
     
         4 . The IC package feeder as claimed in  claim 1 , wherein the first rod members of said IC package path unit are longitudinally fixedly mounted on said top board and movable comb plate; the second rod members of said IC package path unit are perpendicularly to a transversely extended base bar of said IC package path unit and arranged in parallel for synchronous movement with said base bar relative to the first rod members of said IC package path unit to adjust the pitch of said IC package passages.  
     
     
         5 . The IC package feeder as claimed in claimed  4 , wherein said platform comprises said platform comprises a bottom board, said bottom board having two sliding grooves arranged in parallel on a top side near a front side thereof and transversely extended two opposite lateral sides of said bottom board, two sliding rails respectively slidably mounted in said sliding grooves, a top board mounted on said bottom board above the sliding rails in said sliding grooves, said top board having a plurality of transverse slots corresponding to the sliding grooves of said bottom board; the second rod members and base bar of said IC package path unit are respectively fastened to the sliding rails in the sliding grooves of said bottom board by screws being inserted through the transverse slots of said top board.  
     
     
         6 . The IC package feeder as claimed in  claim 1 , wherein said cover is mounted on two side blocks at two opposite lateral sides of said platform, said side blocks each having a vertical mounting slots and a screw respectively inserted through said vertical mounting slots and fastened to said platform to vertically adjustably fasten the corresponding side block to said platform.  
     
     
         7 . The IC package feeder as claimed in  claim 6 , wherein said cover is fastened to said side blocks and horizontally adjustable in longitudinal direction.  
     
     
         8 . The IC package feeder as claimed in  claim 7 , wherein said cover comprises two longitudinal slots arranged in parallel near two opposite lateral sides thereof, and two screws respectively inserted through said longitudinal slots threaded into the topmost edges of said side blocks.  
     
     
         9 . The IC package feeder as claimed in  claim 1 , wherein said cover is a transparent plate.  
     
     
         10 . The IC package feeder as claimed in  claim 1 , further comprising sideboards bilaterally fastened to a rear side of said platform and arranged in parallel, said sideboards each having a plurality of vertical slots, a plurality of transverse rods connected between said sideboards, and a plurality of screws respectively inserted through the vertical slots of said sideboards and threaded into two opposite ends of each of said transverse rods to vertically adjustably secure said transverse rods to said sideboards in horizontal at different elevations.
