<P>PROBLEM TO BE SOLVED: To keep a door as is by instantly applying a brake force when the door starts opening while an operation inhibition condition is detected, and allow an operator to close the door by a handle operation based on the operator's will. <P>SOLUTION: A control circuit 121 includes a brake circuit 24 capable of braking revolution of a motor 8 by short-circuiting an electric circuit between two terminals of the motor 8. While the operation inhibition condition is being detected, if opening of the door from a totally closed state by a door opening operation of a handle is detected, the detection triggers ON-control of the brake circuit 24 to stop the door, and further only when an operation detection switch detects a door closing operation of the handle while the ON-control of the brake circuit 24 is being executed, OFF-control of the brake circuit 24 is executed. <P>COPYRIGHT: (C)2010,JPO&INPIT |
