PURPOSE:To eliminate the mutual interference of magnetic distortion vibrating waves, by giving a short circuit to a Y-direction energizing winding when an X- direction energizing winding is energized and then to the X-direction energizing winding when the Y-direction energizing winding is energized respectively. CONSTITUTION:A short-circuited coil 6 is provided at the edge parts excluding the edges where an X-direction energizing winding 2 and a Y-direction energizing winding 3 are set in order to eliminate the undesired magnetic distortion vibrating waves. Then a short circuit is given to the winding 3 when the winding 2 is generating the electromotive power and the X-direction magnetic distortion vibrating wave. While a short circuit is given to the winding 2 while the winding 3 is generating the electromotive power and the Y-direction magnetic distortion vibrating wave. Thus the undesired magnetic distortion vibrating waves are absorbed by short-circuited coils 2 and 6 or 3 and 6. |
