PURPOSE: To prevent unnecessary motions by conducting judgement of including of any foreign matter even while the instruction is being given from a manual switch for a door glass to elevate.
CONSTITUTION: In case a full close switch 60 is on and the motor drive current exceeds a threshold, a transistor 58 is turned on with signal from the second OP amplifier 48, and an emergency relay circuit 30 is energized to be changed over into the second contact 30B. Thereby current feed to the first coil 22 is shut off while current is fed to the second coil 24 irrespective of the position of a manual rise switch 28, and a motor 12 is rotated reversely (door glass sinking). If including of any foreign matter occurs even while the door glass is rising with manual operation, the door glass can be sunk irrespective of the position of the manual rise switch 28, i.e. its being on, which allows preventing crush of the included foreign matter or damage of door glass, etc.
