Abstract

PURPOSE:To find out the troubles of a proximity switch beforehand by providing a function sensor to check the proximity switch, checking the action of the proximity switch beforehand synchronously with opening and closing a door and providing a safety device not to rotate a motor unless acting synchronously. CONSTITUTION:A proximity switch 7 to sense the vibration of a motor 1 generated by unbalanced quantity inside a rotor 5 is provided on the driving motor 1. Further, a function sensor to sense the function of the proximity switch 7. A switch 11 at the lower section of a door 6 is off when the door 6 is opened at the time of setting or removing a sample, and also a solenoid 8 of the function sensor is off to locate an actuator 10 between the motor 1 and the proximity switch 7. Also, the solenoid 8 is sucked when the door 6 is closed to secure a given distance between the motor 1 and the proximity switch 7. In other words, the on and off action of the proximity switch 7 is checked every time the door 6 is opened and closed, and the action is judged abnormal if not acting synchronously not to rotate the rotor 5.
