The piezoelectric vibrator includes the piezoelectric bar having a plurality of piezoelectric plates alternately stacked and a plurality of vibration sectors divided vertically and horizontally with respect to the direction in which the piezoelectric plates are stacked. By employing flip-flops on the path from the logic element to the elastic store and on the path from the elastic store to the logic element, data is transmitted faster, resulting in the ability for both the previous data state and the next data state to be transmitted simultaneously, in one clock cycle, requiring half of the transmission time required by prior art. The drive mechanism is configured to rotationally drive the rotating member.
