PURPOSE:To drive plural necessary driving devices with one motor by executing the rotational direction driving of the first and second turntables and the shaft direction sliding driving of the second turntable with one motor. CONSTITUTION:When energizing is executed from a driving control circuit to a driving coil 7 in the condition to stop the rotation of a rotary shaft 1 by a stopper 11 to form a rack for gearing to a gear 1c formed at one edge of the rotating shaft 1, a driving magnet 5 is rotated. Simultaneously, the projecting part 2b of a turntable 2 for an optical type video disk is shifted in the lower direction along the sending groove 1b of the rotary shaft 1, and the projecting part 2b fitted at the sending groove 1b of the rotary shaft 1 is shifted and stopped up to the terminal of the groove 1b. Here, when the engagement of the gear 1c formed at one edge of the rotary shaft 1 and the stopper 11 is released, the rotary shaft 1 and a turntable 1a for a compact disk can be rated and rotated.
