<p><P>PROBLEM TO BE SOLVED: To individually stop surfaces of a rotator accurately at a displaying position. <P>SOLUTION: A die 10, a motion converting mechanism 40 and a pulse motor 30 are incorporated in a housing 20 in such a manner that the die 10 accurately displays an origin surface and the other surfaces under a state wherein the step value of an excitation pattern of the pulse motor 30 is m. In a control section 70, when the die 10 is stopped and the other surface is displayed, a pulse is continuously output until an angle of the other surface is sensed by a surface sensing sensor 60. When the angle of the other surface is sensed, the pulse is output by a quantity of remaining steps being equivalent to a difference between a step value commanded by the pulse motor 30 at the time of sensing and the step value m. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
