The second piezoelectric body 14 of a rotation-detecting element 15 which is brought into contact with the irregularities of the moving body 15 generates induced charges, corresponding to the irregularities 12 due to the elastic deformation of a second elastic body 13 which is caused by the rotation of the moving body 5 and controls the rotating speed and rotational angle of the moving body 5, by using pulse signals obtained from the induced charges. Therefore, the information on the stoppage of rotation and the accuracy of rotating speed for the moving body 5 can be improved. In addition, the counting accuracy can also be improved.
