<p><P>PROBLEM TO BE SOLVED: To provide an elevator control device capable of accurately landing a car on a floor, and capable of detecting a variation quantity of car inside weight simultaneously with landing floor detection of the car. <P>SOLUTION: In a wall surface part of a hoistway 2, reflecting members 8a-8c having a reflecting surface of the light are projected in a position corresponding to a door openable-closable position of the car 1 in respective stopping story floors 7a-7c. Each of the reflecting members 8a-8c is a substantially trapezoidal shape in a cross-sectional shape in the vertical direction, and has an oblique upward turning reflecting surface, an oblique downward turning reflecting surface and a vertical reflecting surface arranged between them. A front upper part of the car 1 opposed to the reflecting members 8a-8c is provided with a light generating-light receiving device 9 having a first light sender-receiver 9a for receiving the reflected light by irradiating the light to the oblique upward turning reflecting surface of the reflecting members 8a-8c, a second light sender-receiver 9b for receiving the reflected light by irradiating the light to the oblique downward turning reflecting surface of the reflecting members 8a-8c and a third light sender-receiver 9c for receiving the reflected light by irradiating the light to the vertical reflecting surface of the reflecting members 8a-8c. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
