PURPOSE:To synchronize the rotation of a rotating shaft and that of a step motor, by driving the step motor with a pulse signal in accordance with the rotating angle and rotating direction of the rotating shaft when the motor is rotated. CONSTITUTION:An angle setter 26 has a rotating shaft 34 to set up the rotating angle of a step motor 18. When the rotating shaft 34 is rotated counterclockwise as viewed from the rotating shaft side, a pulse signal is outputted to a line 36 in order to rotate the step motor 18 clockwise as viewed from its shaft 20 side. When a rotating shaft 30 is rotated clockwise, a pulse signal is outputted to a line 38 in order to rotate the step motor 18 counterclockwise. |
