    摘要: A laser surveying equipment includes a laser beam luminous section, a suspending reflection member suspended in such a manner as to reflect laser beam radiated from the laser beam luminous section upward and always to direct the optical axis of such reflected light in the perpendicular direction, and a projection lens system adapted to project the laser beam after forming it into a generally parallel flux of light. A rotary reflection member can be rotatably arranged in order to displace by approximately 90 degree an optical path of parallel flux of light obtained from the projection lens system and to scan the parallel flux of light toward a surveying object within a horizontal plane.

    摘要: Angle measuring apparatus such as a transit has a pair of superimposed discs which are rotatable with respect to each other. One of the discs is rotatable with a viewing telescope support which has a vertically extending rotatable shaft received in a stationary shaft. A commercially available bearing is used between the shafts with the inner race fitted to the rotatable shaft and the outer race to the stationary shaft. The outer race of the bearing further carries the other of the disc.
