Abstract

PURPOSE: To arrange so that a laser beam may be catched correctly by fixing an angle formed by a light-receiving instrument and a laser palne all the time and making a laser beam incident from the front of a light-receiving face of a light- receiving instrument.
CONSTITUTION: With regard to a light-receiving device arranged on an arm 2 of an operating machine equipped with a boom 1, an arm 2 and a bucket 3 and which receives a reference laser beam spread on a finished face in parallel, a device for varying the angle of a light-receiving instrument which changes an angle (angle of light-receiving instrument) formed by a straight line connecting an arm drive point P with a bucket drive point Q and the light-receiving face of a light-receiving instrument 4 for the light-receiving device is controlled with the assistance of a controller in such manner that the formula α+β+θ+ϕ=π, when a boom angle is represented by α, an arm angle β, a finished face inclination angle θ and a light- receiving instrument angle ϕ.
