TURNTABLE, A METHOD FOR MANUFACTURING THE SAME, AND A OPTICAL DISC DRIVE SYSTEM USING THE TURNTABLE, ESPECIALLY CONCERNED WITH UNIFYING A MAGNET AND THE BODY OF THE TURNTABLE AND ATTACHING RIBS FOR TENSION AND A RUBBER FOR SLIP PREVENTION

摘要

PURPOSE: A turntable, its manufacturing method, and an optical disc drive system using the turntable are provided to manufacture a turntable by using an insert-injection process in order to reduce the number of parts and the manufacturing cost and prevent separation of a magnet. CONSTITUTION: The turntable comprises a body(20), a magnet(30), and a buffering member(40). The body(20) includes a disc combination unit(22) and a bracket(23). The disc combination unit(22) is integratedly formed with the bracket(23) and positioned over an axis portion having an axial combination hole. The backet(23) makes the optical disc be safely seated thereon. The magnet(30) is integratedly formed on the body(20). The buffering member(40) is adhered to the brink of the bracket(23). The body(20) is formed via an injection molding process while the magnet(30) is formed via an insert-injection molding process. The disc combination unit(22) has tension ribs(22a) equidistantly arranged.
