    摘要: An apparatus for detecting people waiting for an elevator. A detecting unit detects the number of people waiting on the basis of an image from an image pickup unit and delivers that number to a corresponding second people waiting detecting unit. The apparatus includes a unit which generates a coefficient depending on a percentage of overlap of the field of view of a reference image pickup unit, which is one of several image pickup units, with the field of view of a different image pickup unit on the basis of data on the allocation of an elevator, and calculates the number of waiting people in the overall hall from the respective numbers of waiting people output from the plurality of image pickup units and those coefficients. The coefficient generating unit generates a maximum coefficient for the reference image pickup unit and a smaller coefficient for any remaining image pickup unit based on the of overlap of the field of view of the respective image pickup units. Thus, even if the fields of view of the plurality of image pickup units overlap, an accurate number of people waiting in the elevator hall, and free from an error in detection, is detected.

    摘要: An elevator in which the sheave diameter is reduced and the attendant lowering of the rope life and strength is suppressed to secure safety and reliability. To this end, a rope is used in which a plurality of element wires constituting the wire rope are each covered with resin material and the whole wire rope is covered with resin material, thereby reducing the wear due to slippage between the element wires and the wear due to contact with the sheave, which wear occurs when the rope is entrained around the sheave. When the elevator sheave diameter is reduced, a worried lowering of the rope life can be suppressed or the rope life can be improved. Thus, it is possible to achieve reduction of size and weight of equipment including motors and hoists, installation space saving for elevators, improved safety and reliability of the system by virtue of the increased rope life.
