Abstract
PURPOSE: To ensure the safety of passengers standing close to a doorway of a car by delaying a door opening and closing speed by a door control circuit when it is detected by a signal of a load detector that passengers almost reaching a capacity of the car get on the car. CONSTITUTION: When a load in a car is small, an output of an inversion amplifier 3 for an output from a load detector 1 becomes larger than a reference voltage Vo , an output VS of a comparator 7 becomes L to turn on a switching element 16 in a door control circuit 12 through an inverter 11, a normal output of a door pattern generator 13 is input in a door opening and closing circuit 15, and a door is opened and closed at a normal speed by a motor 18. On the other hand, when a load in the car almost reaches its capacity, an output VS from the comparator 7 of a load setting device 2 becomes H, a switching element 17 is turned on, an output of a low speed pattern generator 14 is input in the door opening and closing circuit 15, and a door speed becomes a low speed. Consequently, it is possible to ensure the safety of passengers without reducing the quality of service.
