Abstract

PURPOSE:To provide a measuring device for inclining amount which has a high reliability and a hih endurance, by a method wherein a laser, emitting a laser light in an axial direction of a long post, is supported in a given direction by means of a gimbal structure, and a photo transducer, which spins within a plane crossing an axial line at right angles, is installed at the other end of the long post. CONSTITUTION:A laser device 2 is supported at a gimbal gyro system perpendicular supporter 3, secured at one end and at the inside of a post for depth processing device, which is of an enclosure hollow pipe structure, and 30 CdS transmission elements are arranged in a row around a center shaft Z-Z at intervals of 10mm. on a rotary light-receiving arm 4, turning around the center shaft Z-Z of the other end within a horizontal plane by means of a turning device 5. When a laser beam is incident upon one of the light transmission elements resulting from the inclination of the post 1, an element number signal is outputted from a binary transducer 10, and simultaneously, the angle signal of the rotary light-receiving arm 4 is outputted. Thus, the inclining amount of the post 1 can be found by means of a CPU15. The device is housed in the post 1, and as a result, it has a high endurance against an external influence.
