A polyhedron inspection apparatus 10 includes a polyhedron inspection feeder 12 having a passage forming member 22 for inspecting a surface of cubic chip W. The polyhedron inspection feeder 12 is formed with a V-letter groove, and includes two rotating feed sections 25 A and 25 B arranged on the midway of the passage forming member 22 . The rotating feed sections 25 A and 25 B are individually formed with grooves having V-letter type, U-letter type and V-letter type sectional shapes in succession. The passage forming member 22 is provided with a shooter 18 for moving the chip W one by one in a state of being estranged from each other, and further, is provided with cameras 13 A to 13 D for inspecting the surface of the chip W, and retrieve element 30 for retrieving the chip W in accordance with the inspection result.

1. A polyhedron inspection feeder, comprising a passage forming member for moving an object to be inspected in a predetermined moving direction, whereinthe passage forming member includes a groove that has first and second opposite side walls having first and second inclined angles, respectively, said first and second inclined angles varying along the moving direction of the object so that the object is rotated by a predetermined angle while being moved in said moving direction; andsaid groove comprises segments having V-shaped, U-shaped and V-shaped cross sections, respectively. 2. The polyhedron inspection feeder of claim 1, further comprising another passage forming member for moving, together with said passage forming member, said object in said moving direction, whereinsaid another passage forming member includes another groove that has third and fourth opposite side walls having third and fourth inclined angles, respectively, said third and fourth inclined angles varying along the moving direction of the object so that the object is rotated by another predetermined angle while being moved in said moving direction; andsaid another groove comprises segments having U-shaped, V-shaped and U-shaped cross sections, respectively. 3. The polyhedron inspection feeder of claim 2, wherein, in said another passage forming member, said segments having U-shaped, V-shaped and U-shaped cross sections, respectively, are arranged in the recited order along the moving direction of the object. 4. The polyhedron inspection feeder of claim 2, wherein the grooves of said passage forming members are successively arranged along the moving direction of the object. 5. The polyhedron inspection feeder of claim 2, wherein, in said another passage forming member, the third and fourth side walls define therebetween a constant angle in the segment of V-shaped cross section, and the third side wall and a bottom of said another groove define therebetween said constant angle in the segments of U-shaped cross section. 6. The polyhedron inspection feeder of claim 1, comprising two said passage forming members which are continuously combined with each other. 7. The polyhedron inspection feeder of claim 6, wherein the grooves of said passage forming members are successively arranged along the moving direction of the object. 8. The polyhedron inspection feeder of claim 1, wherein said segments having V-shaped, U-shaped and V-shaped cross sections, respectively, are arranged in the recited order along the moving direction of the object. 9. The polyhedron inspection feeder of claim 8, comprising two said passage forming members the grooves of which are successively arranged along the moving direction of the object. 10. The polyhedron inspection feeder of claim 1, wherein the first and second side walls define therebetween a constant angle in the segments of V-shaped cross section, and the first side wall and a bottom of said groove define therebetween said constant angle in the segment of U-shaped cross section.
