<p>PURPOSE: An automatic stop motion is provided to prevent a second malfunction linked to a motor unit and overload of the motor unit by secluding power supplied to the motor unit through a controller. CONSTITUTION: An automatic stop motion comprises a stop unit(100). The stop unit comprises a power transmission shaft(110), a first flange(130), a second flange(140), an elastic member(150), a power security unit(170), and a sensor. The power transmission shaft is connected to an operation unit with power. The first flange is connected to the power transmission shaft to be moved and transfers torque to the power transmission shaft. The second flange is connected to a shaft of the operation unit and contacted with the first flange. The elastic member applies elastic force so that the first flange adheres closely to the second flange. The power security unit is formed on a surface, in which the first flange and the second flange are contacted and separates the first flange from the second flange when the power operation unit is stopped. The sensor is next to the first flange and applies signals to the controller to stop the power when the first flange is separated from the second flange.</p> |
