DOOR CONTROLLER FOR ELEVATOR

PURPOSE:To improve the safety of a door by preventing the engagement element of a door and an engaging roller from being released by installing a means for detecting the stop of a cage and allowing the door to be opened when the cage is set within a door zone range and the detecting means operates. CONSTITUTION:A detecting means for detecting the stop of a cage 1, i.e., speed detector 20 and a means for opening a door according to the operation of the detecting means, i.e., contact point DZ, contact point 23b, and a relay 37 are installed. During the traveling of the cage 1, an output is generated on the speed detector 20, and a relay 23 is energized, and since the contact point 23b is in opened state, the relay 37 for applying an opening instruction to the cage door is made independent. When the cage 1 stops in the door zone range, the contact point DZ and the contact point 23b are in closed state, and the relay is energized by a circuit P-34b-DZ-36b-OLS-37-N, and a door motor 35 is driven by a circuit P-37a-35-37a-N, and when the cage door 5 is opened, also the getting-on field door can be opened simultaneously.
