<p>PURPOSE:To lock a door at a closing position without using a detection switch by locking a trailing pulley through an automatic door controller, electromagnetic lock controller, and a pulse output means by using a locking mechanism. CONSTITUTION:An automatic door controller 30 consisting of a main control circuit 31, speed control circuit 32, speed judging circuit 33, and a direction judging circuit 34, and an electromagnetic lock controller 41 are installed, and a locking mechanism 8 consisting of an electromagnet 15, armature, leaf spring, etc., is installed on the fixed side. The pulse P proportional to the shift of a door 6 is inputted from a DC brushless motor 1, and the controller 30 judges the stop of the door 6 at a closing position, and the electric conduction to the electromagnet 15 is controlled by the controller 41, and the locking mechanism 8 is locking-operated to lock a trailing pulley 4 onto the fixed side, and the door 6 is locked at the closing position.</p> |
