PURPOSE:To prevent a misoperation where a spindle is revolved while fixing an actuator with a clamp by permitting the revolution of the spindle only when detecting that the fixed state of the actuator is released. CONSTITUTION:When an actuator clamp fixing part 7 is turned to an ON display position, the actuator is fixed and it is released at an OFF display position. Then a microswitch 9 is operated by a plate 8. A spindle is revolved with operation of a start switch for revolution of the spindle only when the switch 9 is operated. Therefore the revolution of the spindle is inhibited when the part 7 is set at the ON display position and despite the operation of the start switch. |
