Abstract

PURPOSE:To achieve a turn table having shortened rising time and falling time, by fixing a drive section at the inside of the turn table. CONSTITUTION:A.C. current having predetermined frequency is provided to the coil of a drive source 13 thus to provide the magnetic force of N and S polarity alternatively to the core. A turn table 11 is rotated by the attraction and the repulsion between a ring magnet 12 where N and S poles are magnetized alternatively and the magnetic force of the core. Consequently the rising and the falling times can be shortened.
