ELEVATOR POSITION DETECTION DEVICE

WIPO Patent Application WO/2015/159455

A1

A detected body (11) is provided inside of an elevator shaft (1), and a detector (21) is provided on an elevating body. The detected body comprises a first detected plate (12) on which an ID column (15) is provided, and a second detected plate on which a clock column (16) is provided. The detector (21) is provided with: a first detection unit (22) which, when the ID column (15) passes through a first detection region (224), outputs, as the ID signal, the time-series signal which switches states at boundary positions between first characteristic portions (low-resistivity portions (15a)) and second characteristic portions (high-resistivity portions (15b)) of the ID column (15), and a second detection unit (23) which, when the clock column (16) passes through a second detection region (234), outputs, as the clock signal, the time-series signal which switches states at boundary positions between first characteristic portions (low-resistivity portions (16a)) and second characteristic portions (high-resistivity portions (16b)) of the clock column (16). A processing unit (31) specifies the position of the elevating body within the elevator shaft by reading the state of the ID signal at positions where the clock signal switches states.
