Abstract: The invention is directed to an angle-measuring instrument such as a theodolite, tacheometer or the like having a coarse-fine drive arrangement for presetting a circle part of a graduated circle to a predetermined read-out value. In a preferred embodiment, a coaxial coarse-fine drive arrangement is actuated by a single control knob which is part of an adjustable drive which can be operated in two positions. In the first position, the adjustable drive functions as a coarse drive and includes a spur gear that meshes with a gear on the carrier of the graduated circle to permit adjusting the circle part to obtain a coarse setting thereof. When the control knob and adjustable drive are moved into the second position, the drive becomes completely disengaged from the carrier and functions as a fine drive that operates on a plane-parallel plate pivotally mounted in the read-out optical transmission path of the instrument to finely adjust the light rays passing therealong.
