Patent ID: 7108582

Claim:
A polishing machine that uses a polishing tape, said polishing machine comprising: a polishing head for contacting said polishing tape to a disk-shaped target object to be polished; a pad that is movably provided to said polishing head and serves to press said polishing tape onto said target object; a rotary shaft that is connected to said polishing head in a direction of contact surface between said polishing tape and said target object; a rotary-and-reciprocating motion device adapted to rotate said polishing head around the axial line of said rotary shaft and to move said polishing head reciprocatingly along said axial line; and a moving device adapted to undergo a reciprocating motion perpendicularly to said target object while supporting said target object; wherein said moving device includes a rotating device for rotating said target object around the center thereof, said rotating device having a rotary shaft part that is rotated by a driving part and a rotary support part that contains said rotary shaft part inside and has a support surface for supporting said target object, said rotary support part rotating with said rotary shaft part and engaging said rotary shaft so as to be movable axially, said rotary-and-reciprocating motion device rotating said polishing head and said moving device moving said target object when said contact surface of said target object is polished such that said pad is moved outward to cause said polishing tape to protrude and to thereby come to contact said target object over said contact surface.
