PROBLEM TO BE SOLVED: To provide a positional information acquiring device in an elevator shaft acquiring exact positional information in the elevator shaft even if an obstacle blocking a laser beam exists in the elevator shaft, and to provide a guide device for the positional information acquiring device. SOLUTION: The device for acquiring the positional information of a measured object in the elevator shaft 1 includes: a laser scanner 10 scanning the measured object in the elevator shaft 1 by the use of the laser beam, measuring a distance to the measured object receiving the reflected light of the scanning laser beam from the measured object, and measuring the positional information of the measured object based on the measured distance to the measured object and the irradiation angle of the laser beam toward the measured object; and a storage section 53 storing the positional information of the measured object measured by the laser scanner 10. The laser scanner 10 is movably supported by guide members 30a, 41, 42, 43 arranged on a car 30 ascending and descending in the elevator shaft 1. COPYRIGHT: (C)2011,JPO&INPIT
