Abstract
A rotating and driving system for a survey instrument, wherein a driven wheel is mounted on a shaft of a movable unit and a slide baseplate is disposed on the shaft so as to be movable in a direction perpendicular to the axis of the shaft. A gear, driven by a motor, is mounted on the slide baseplate in such a position that the gear can be engaged with the driven wheel when the slide baseplate is pushed in the proper direction. By providing engaging force between the driven wheel and the gear, backlash is suppressed, and positioning can be achieved at higher accuracy.
Claims5
