Title:
LASER SURVEY APPARATUS
Document Type and Number:
Japanese Patent JP3908297
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To improve operability and setting accuracy by adapting so that a direction of a laser survey apparatus is set automatically when an elevation angle of the laser survey apparatus is to be set.
SOLUTION: The laser survey apparatus is provided at least with a reflecting body-detecting device 3 for projecting detection laser beams, a rotating device 151 for rotating the detecting device, and a reflecting body for reflecting the detection laser beams to the detecting device 3. The reflecting body-detecting device 3 includes a light-emitting part for generating detection laser beams, a rotary part for reciprocating and scanning laser beams, a reflecting light- detecting part for detecting laser beams reflected from the reflecting body and a scanning control part for controlling the rotary part. The detecting device 3 detects the reflecting body to be measured and the rotating device determines a direction of the detecting device 3, whereby a direction of the laser survey apparatus is automatically set.
