A rotary portion(600) and a servo-motor(100) are combined with each other on the same vertical rotary shaft in an accepting space of the rotary body pieces. The servo-motor includes a rotary shaft combined with the rotary portion. The rotary portion is rotated by the rotational force of the servo-motor. The shaft rotation of each rotary body piece is performed by the rotation of the rotary portion.
