PURPOSE:To set an azimuth angle accurately and quickly, by mounting a gyrocompass, which is attached to a laser light emitting device, on a slide table, and fixing the slide table on a circular table. CONSTITUTION:A laser light emitting device 5 has a laser light emitting part, which can be rotated in a vertical plane. and slit shaped laser light is emitted in the vertical direction from the light emitting part. The light emitting device 5 is attached to a gyrocompass 6. The gyrocompass 6 is mounted on a slide table 7. The slide table 7 is fixed to a circular table 9. |
